RISK FACTOR SUMMARY

Our  business  is  subject  to  significant  risks  and  uncertainties  that  make  an  investment  in  us  speculative  and  risky.  Below  we  summarize  what  we
believe are the principal risk factors but these risks are not the only ones we face, and you should carefully review and consider the full discussion of our
risk  factors  in  the  section  titled  “Risk  Factors,”  together  with  the  other  information  in  this  Annual  Report  on  Form  10-K.  If  any  of  the  following  risks
actually  occurs  (or  if  any  of  those  listed  elsewhere  in  this  Annual  Report  on  Form  10-K  occur),  our  business,  reputation,  financial  condition,  results  of
operations, revenue, and future prospects could be seriously harmed. Additional risks and uncertainties that we are unaware of, or that we currently believe
are not material, may also become important factors that adversely affect our business.

• Our quarterly and annual operating results may vary from period to period, which could result in our failure to meet expectations with

•

•

•

respect to operating results and cause the trading price of our stock to decline.
If we do not successfully anticipate market needs and opportunities or are unable to enhance our solutions and develop new solutions that
meet those needs and opportunities on a timely or cost-effective basis, we may not be able to compete effectively and our business and
financial condition may be harmed.
If we fail to continue to effectively scale and adapt our platform to meet the performance and other requirements of our customers, our
operating results and our business would be harmed.
If  we  are  unable  to  renew  existing  subscriptions  for  our  IT,  security  and  compliance  solutions,  sell  additional  subscriptions  for  our
solutions and attract new customers, our operating results would be harmed.

• Our  current  research  and  development  efforts  may  not  produce  successful  products  or  enhancements  to  our  platform  that  result  in

significant revenue, cost savings or other benefits in the near future.

• Our platform, website and internal systems may be subject to intentional disruption or other security incidents that could result in liability

and adversely impact our reputation and future sales.

• Our sales cycle can be long and unpredictable, and our sales efforts require considerable time and expense. As a result, revenues may

vary from period to period, which may cause our operating results to fluctuate and could harm our business.

• Adverse economic conditions or reduced IT spending may adversely impact our business.
• Our IT, security and compliance solutions are delivered from 14 shared cloud platforms, and any disruption of service at these facilities
would interrupt or delay our ability to deliver our solutions to our customers which could reduce our revenues and harm our operating
results.

• We  face  competition  in  our  markets,  and  we  may  lack  sufficient  financial  or  other  resources  to  maintain  or  improve  our  competitive

•

position.
If our solutions fail to detect vulnerabilities or incorrectly detect vulnerabilities, our brand and reputation could be harmed, which could
have an adverse effect on our business and results of operations.
•
If we are unable to continue the expansion of our sales force, sales of our solutions and the growth of our business would be harmed.
• We  rely  on  third-party  channel  partners  to  generate  a  substantial  amount  of  our  revenues,  and  if  we  fail  to  expand  and  manage  our

distribution channels, our revenues could decline and our growth prospects could suffer.

• A significant portion of our customers, channel partners and employees are located outside of the United States, which subjects us to a
number of risks associated with conducting international operations, and if we are unable to successfully manage these risks, our business
and operating results could be harmed.
If the market for cloud solutions for IT, security and compliance does not evolve as we anticipate, our revenues may not grow and our
operating results would be harmed.

•

• Our business and operations have continued to grow since inception, and if we do not appropriately manage any future growth, or are

unable to improve our systems and processes, our operating results may be negatively affected.

• A portion of our revenues are generated by sales to government entities, which are subject to a number of challenges and risks.
• Undetected software errors or flaws in our solutions could harm our reputation, decrease market acceptance of our solutions or result in

liability.

• Our solutions could be used to collect and store personal information of our customers’ employees or customers, and therefore privacy

and other data handling concerns could result in additional cost and liability to us or inhibit sales of our solutions.

• Our  solutions  contain  third-party  open  source  software  components,  and  our  failure  to  comply  with  the  terms  of  the  underlying  open

source software licenses could restrict our ability to sell our solutions.

• We use third-party software and data that may be difficult to replace or cause errors or failures of our solutions that could lead to lost

customers or harm to our reputation and our operating results.

Table of Contents

Failure to protect our proprietary technology and intellectual property rights could substantially harm our business and operating results.

•
• Assertions by third parties of infringement or other violations by us of their intellectual property rights could result in significant costs

and harm our business and operating results.

Item 1.     Business

Overview

PART I

We  are  a  pioneer  and  leading  provider  of  a  cloud-based  platform  delivering  information  technology  (IT),  security  and  compliance  solutions.  Our
integrated  suite  of  IT,  security  and  compliance  solutions  delivered  on  Qualys'  Enterprise  TruRisk  Platform  enables  our  customers  to:  1)  identify  and
manage their internal and external IT and operational technology (OT) assets across on-premises, endpoints, cloud, containers, and mobile environments;
2)  collect  and  analyze  large  amounts  of  IT  security  data;  3)  discover  and  prioritize  vulnerabilities;  4)  quantify  cyber  risk  exposure;  5)  recommend  and
implement remediation actions; and 6) verify the implementation of such actions. This helps organizations protect their systems and applications from ever-
evolving cyber-attacks and helps achieve compliance with internal policies and external regulations.

Our  cloud  platform  addresses  the  growing  IT,  security  and  compliance  complexities  and  risks  that  are  amplified  by  the  dissolving  boundaries
between  IT  infrastructures  and  web  environments,  the  rapid  adoption  of  cloud  computing,  containers  and  serverless  IT  models,  and  the  proliferation  of
geographically dispersed IT assets. Organizations use our integrated suite of solutions to cost-effectively obtain a unified view of their internal and external
IT and OT asset inventory as well as security and compliance posture across globally-distributed IT infrastructures as our solution offers a single platform
for information technology, information security, application security, endpoint, developer security and cloud teams.

IT infrastructures are more complex and globally-distributed today than ever before, as organizations of all sizes increasingly rely upon a myriad of
interconnected information systems and related assets, such as servers, databases, web applications, routers, switches, desktops, laptops, other physical and
virtual infrastructure, and numerous external networks and cloud services. In this environment, new and evolving digital technologies intended to improve
organizations’  operations  can  also  increase  vulnerability  to  cyber-attacks,  which  can  expose  sensitive  data,  damage  IT  and  physical  infrastructures,  and
result in serious financial or reputational consequences. In addition, the rapidly increasing amount of data and devices in IT environments makes it more
difficult to identify and remediate vulnerabilities in a timely manner. The predominant approach to IT security has been to implement multiple disparate
security products that can be costly and difficult to deploy, integrate and manage and may not adequately protect organizations. As a result, we believe
there is a large and growing opportunity for comprehensive cloud-based IT, security and compliance solutions that detect, measure, prioritize and remediate
cyber risk delivered in a single platform.

We designed our cloud platform to transform the way organizations secure and protect their IT infrastructures and applications. Our cloud platform
offers  an  integrated  suite  of  solutions  that  automates  the  lifecycle  of  asset  discovery  and  management,  security  and  compliance  assessments,  and
remediation  for  an  organization’s  IT  infrastructure  and  assets,  whether  such  infrastructure  and  assets  reside  inside  the  organization,  on  their  network
perimeter, on endpoints or in the cloud. Since inception, our solutions have been designed to be delivered through the cloud and to be easily and rapidly
deployed on a global scale, enabling faster implementation and lower total cost of ownership than traditional on-premise enterprise software products. Our
customers, ranging from some of the largest global organizations to small businesses, are served from our globally-distributed cloud platform, enabling us
to rapidly deliver new solutions, enhancements and security updates.

We believe that our cloud platform provides our customers with unique advantages, including:

•

•

•

•

No hardware to buy or manage. There is no infrastructure or software to buy and maintain thus reducing our customers’ operating costs; all
services are accessible in the cloud via web interface. Qualys operates and maintains the platform.
Real-time visibility in one place, anytime and anywhere.  Our  customers  can  conveniently  see  their  security  and  compliance  posture  across
their global IT and OT asset inventory in one browser window, without plugins or a virtual private network (VPN), whenever and wherever
Internet access is available.
Easy global scanning. Our customers can easily perform scans on geographically distributed and segmented networks at the perimeter, behind
the firewall, on dynamic cloud environments and on endpoints.
Seamless scaling. Our cloud platform is a scalable, comprehensive, and end-to-end solution for the IT, security and compliance needs of our
customers. Our customers can seamlessly add new coverage, users and services after they have deployed our platform.

• Up to date resources. Qualys has one of the largest knowledge bases of vulnerability signatures in the industry. All security updates are made

in real-time.

• Data stored securely. Data is securely stored and processed in a multi-tiered architecture of load-balanced servers. Our encrypted databases

are physically and logically secured.

Table of Contents

We were founded and incorporated in December 1999 with a vision of transforming the way organizations secure and protect their IT infrastructure
and  applications  and  initially  launched  our  first  cloud  solution,  Vulnerability  Management  (VM),  in  2000.  As  VM  gained  acceptance,  we  introduced
additional solutions to help customers manage increasing IT, security and compliance requirements. Today, the suite of solutions that we offer on our cloud
platform and refer to as the Qualys Cloud Apps help our customers detect, measure, prioritize and remediate cyber risk spanning a range of assets across
on-premises, endpoints, cloud, containers, and mobile environments.

We  provide  our  solutions  through  a  software-as-a-service  model,  primarily  with  renewable  annual  subscriptions.  These  subscriptions  require
customers to pay a fee in order to access each of our cloud solutions. We generally invoice our customers for the entire subscription amount at the start of
the subscription term, and the invoiced amounts are treated as deferred revenues and are recognized ratably over the term of each subscription. We continue
to  experience  revenue  growth  from  our  existing  customers  as  they  renew  and  purchase  additional  subscriptions,  as  well  as  from  the  addition  of  new
customers to our cloud platform.

Our cloud platform is currently used by over 10,000 customers worldwide, including a majority of the Forbes Global 100. Our revenues increased to

$554.5 million in 2023 from $489.7 million in 2022 and $411.2 million in 2021.

Our Platform

Our cloud platform consists of a suite of IT security, compliance, web application security, asset management and cloud security solutions, which we
refer to as the Qualys Cloud Apps, that leverage our shared and extensible core services and our highly scalable multi-tenant cloud infrastructure. We also
provide open application program interfaces, or APIs, and other developer tools that allow third parties to embed our technology into their solutions and
build applications on our platform.

Our cloud platform utilizes physical and virtual sensors, and cloud agents that provide our customers with continuous visibility enabling customers
to respond to threats immediately. Customers can extend visibility to all known IT infrastructure using our Out-of-Band Configuration Assessment sensor
for systems that are air-gapped or otherwise difficult to assess.

Our  cloud  platform  automatically  gathers  and  analyzes  security  and  compliance  data  in  a  scalable,  state-of-the-art  backend.  The  technology
underlying our cloud infrastructure enables us to ingest, process, analyze and store a high volume of sensor data coming from our agents, scanners and
passive analyzers, and correlate information at very high speeds in a distributed manner for millions of devices.

Table of Contents

Our cloud platform is delivered to our customers via our 14 global shared cloud platforms, or via our private platform offering, Qualys Private Cloud
Platform (PCP), for customers or partners that want the platform to reside within the customer's shared cloud platform. The PCP is a standalone version of
our multi-layer, multi-tenant services architecture and is a fully integrated turnkey solution, making it more scalable, cost effective and faster to deploy
within a customer's shared cloud platform. Solutions delivered through our PCP are typically on the same subscription basis as solutions delivered through
our  shared  platform.  Our  PCP  utilizes  hardware  and  software  owned  by  us  and  is  physically  located  on  the  customer's  premises.  The  customer  is  not
permitted to take possession of the software or access the software code. We also offer our PCP as a subscription-based platform services to the customer
using a virtual version of our software. This virtualized PCP allows us to extend our security and compliance solutions without the complexity and cost
associated with deploying traditional enterprise software.

Qualys Core Services

Our core services enable our customers to detect vulnerabilities, measure and remediate cyber risk through integrated workflows, management and

real-time analysis and reporting inside their organizations, on the perimeter, on endpoints or in the cloud.

Our core services constitute dynamic and customizable dashboards and centrally managed, self-updating integrated Cloud Apps, through a natively
integrated unified platform. Our interactive, dynamic dashboards and cloud platform allow our customers to aggregate and correlate all of their IT, security
and  compliance  data  in  one  place,  drill  down  into  details,  and  generate  reports  customized  for  different  audiences.  Our  cloud  platform’s  powerful
Elasticsearch clusters enable customers to instantly find detailed data on any asset.

Our core services include:

•

•

Asset Tagging and Management. Enables customers to easily identify, categorize and manage large numbers of assets in highly dynamic IT
and OT environments and automates the process of inventory management and hierarchical organization of all internal and external assets.
Built on top of this core service is the Qualys GAV framework, which is a global asset inventory service enabling our customers to search for
information  on  any  asset,  scaling  to  millions  of  assets  for  customers  of  all  sizes,  helping  IT  and  security  personnel  to  search  assets  and
maintain an up-to-date inventory on a continuous basis.
Reporting and Dashboards. A highly configurable reporting engine that provides customers with reports and dashboards based on their roles
and access privileges.

• Questionnaires and Collaboration. A configurable workflow engine that enables customers to easily build questionnaires and capture existing

•

•

•

business processes and workflows to evaluate controls and gather evidence to validate and document compliance.
Remediation and Workflow. An integrated workflow engine that allows customers to automatically generate helpdesk tickets for remediation
to manage compliance exceptions based on customer-defined policies, enabling subsequent review, commentary, tracking and escalation. This
engine automatically distributes remediation tasks to IT administrators upon scan completion, tracks remediation progress and closes open
tickets once patches are applied and remediation is verified in subsequent scans.
Big  Data  Correlation  and  Analytics  Engine.  Provides  Elasticsearch  capabilities  for  indexing,  searching  and  correlating  large  amounts  of
security and compliance data with other security incidents and third-party security intelligence data. Embedded workflows enable customers
to quickly assess risk and access information for remediation, incident analysis and forensic investigations.
Alerts  and  Notifications.  Creates  email  notifications  to  alert  customers  of  new  vulnerabilities,  malware  infections,  scan  completion,  open
trouble tickets and system updates.

Qualys Cloud Apps

Many organizations have an array of heterogeneous point tools that do not interoperate well and are difficult and costly to maintain and integrate,
making  it  difficult  for  Chief  Information  Officers  (CIOs)  and  Chief  Information  Security  Officers  (CISOs)  to  obtain  a  single,  unified  view  of  their
organization’s security and compliance posture. Qualys’ Enterprise TruRisk Platform and its Cloud Apps help organizations escape this tool-fragmentation
dilemma  by  drastically  simplifying  their  security  stacks  and  regaining  unimpeded  visibility  across  their  on-premises,  endpoints,  cloud,  container,  and
mobile environments.

The  Cloud  Apps  are  self-updating,  centrally  managed  and  tightly  integrated,  and  cover  a  broad  range  of  functionality  in  areas  such  as  asset

management, vulnerability management, risk mitigation, threat detection and response, compliance and cloud security solutions.

8

Table of Contents

We  believe  that  our  applications  are  easy  to  use  and  provide  our  customers  with  a  high  level  of  control  because  our  applications  are  part  of  one

platform, share a common user interface, utilize the same scanners and agents, access the same collected data, and leverage the same user permissions.

Our customers can subscribe to one or more of our 20+ Cloud Apps based on their initial needs and expand their subscriptions over time to new
areas within their organization or to additional Qualys solutions to develop a more complete understanding of their respective environment's IT, security
and compliance posture and remediate cybersecurity risk. Many of our customers use multiple Cloud Apps, some of which are noted below:

Asset Management

Cybersecurity Asset Management (CSAM): CSAM is an all-in-one solution that leverages the power of our cloud platform with its multiple native
sensors and CMDB synchronization to continuously inventory known and unknown assets, discover installed applications, and overlay business and risk
context  to  establish  asset  criticality.  It  identifies  unauthorized  or  end-of-life  and  end-of-service  software  and  the  absence  of  required  security  tools,  and
assesses the health of the attack surface. Further, CSAM enables response options with threat alerts and software removal and delivers regulatory reporting
in  support  of  the  Federal  Risk  and  Authorization  Management  Program  ("FedRAMP"),  PCI-DSS  and  other  mandates.  CSAM  includes  External  Attack
Surface Management (EASM), which allows discovery of internet facing unknown assets.

Vulnerability Management

Vulnerability  Management,  Detection  and  Response  (VMDR):  VMDR  enables  organizations  to  automatically  discover  every  asset  in  their
environment,  including  unmanaged  assets  appearing  on  the  network,  inventory  all  hardware  and  software,  and  classify  and  tag  critical  assets.  VMDR
continuously assesses these assets for the latest vulnerabilities and applies the latest threat intel analysis to prioritize actively exploitable vulnerabilities.
VMDR  automatically  detects  the  latest  superseding  patch  for  the  vulnerable  asset  and  easily  deploys  it  for  remediation.  Finally,  VMDR  quantifies  risk
across vulnerabilities, assets and groups of assets helping organizations proactively reduce cyber risk exposure and track cyber risk reduction over time. By
delivering all this in a single app workflow, VMDR automates the entire process and significantly accelerates an organization’s ability to respond to threats,
thus preventing possible exploitation across on-premises, endpoints, cloud, containers, and mobile environments.

Web Application Scanning (WAS): WAS continuously discovers and catalogs web applications – including new and unknown ones – and detects
vulnerabilities and misconfigurations in web apps and APIs. Scaling to thousands of scans, it conducts incisive, thorough and precise testing of browser-
based web apps, mobile app backends, and Internet of things (IoT) services. WAS' powerful API enables integration with other systems and allows teams to
detect  issues  within  DevOps  environments  early  in  the  application  development  process.  Bundled  malware  detection  capability  with  WAS  uses
reputational,  behavioral,  antivirus,  and  heuristic  analyses  to  identify  and  alert  on  malware  infecting  a  user's  websites.  By  Integrating  WAS  with  manual
testing tools and bug bounty solutions, customers can build a comprehensive web application vulnerability testing program.

Risk Mitigation

Patch Management (PM): PM provides automated patch deployment capabilities for Windows, Linux, Mac and third party software by correlating
vulnerabilities  and  the  right  set  of  remediation  including  patches  and  configuration  fixes.  It  continuously  gathers  and  uploads  telemetry  about  installed
software, open vulnerabilities and missing patches to our cloud platform. The resulting shared visibility of assets and their posture enables IT and security
teams to collaborate using common vulnerability-centric terminology and provides a consistent data set to analyze, prioritize, deploy and verify patches
more efficiently.

Custom Assessment and Remediation (CAR): CAR enables security architects to create custom scripts in popular scripting languages, user-defined
controls  and  automation,  all  seamlessly  integrated  within  existing  programs  to  quickly  assess,  respond  to  and  remediate  threats  across  global  hybrid
environments.

Threat Detection and Response

Multi-Vector  Endpoint  Detection  and  Response  (EDR):  Traditional  endpoint  detection  and  response  solutions  focus  only  on  endpoint  activity  to
detect attacks. As a result, they lack the full context to analyze attacks accurately. This leads to an incomplete picture and a high rate of false positives and
negatives, requiring organizations to use multiple point solutions and large incident response teams. Our highly scalable platform fills the gaps by bringing
a  new  multi-vector  approach  and  the  unifying  power  to  EDR,  providing  vital  context  and  comprehensive  visibility  to  the  entire  attack  chain,  from
prevention to detection to response. EDR unifies different context vectors like asset discovery, rich normalized software inventory, end-of-life visibility,
vulnerabilities

and exploits, misconfigurations, in-depth endpoint telemetry, and network reachability with a powerful backend to correlate it all for accurate assessment,
detection and response.

Context Extended Detection and Response (XDR): XDR provides context and clarity to enterprise security operations through risk-focused, single
pane of glass visibility and control to improve enterprise-wide threat detection and incident response. It leverages our cloud platform's response capabilities
-  patching,  fixing  misconfigurations,  killing  processes  and  network  connections,  and  quarantining  hosts  -  to  comprehensively  remediate  cyber  security
threats identified by Qualys’ XDR.

Compliance

Policy Compliance (PC): PC performs automated security configuration assessments on IT systems throughout a network, helping to reduce risk and
continuously  ensure  compliance  with  internal  policies  and  external  regulations.  PC  leverages  out-of-the-box  library  content  to  fast-track  compliance
assessments using industry-recommended best practices. PC also provides a centralized, interactive console for specifying baseline standards for different
hosts.  By  automating  requirement  evaluation  against  multiple  standards  for  operating  systems,  network  devices,  databases  and  server  applications,  PC
enables the quick identification of security issues and works to prevent configuration drift. PC works to prioritize and track remediation and exceptions,
while demonstrating a repeatable auditable process for compliance management

File Integrity Monitoring (FIM): FIM logs and centrally tracks file change events on common enterprise operating systems in organizations of all
sizes. FIM provides customers with a simple way to achieve centralized cloud-based visibility of activity resulting from normal patching and administrative
tasks, change control exceptions or violations, or malicious activity - then reports on that system activity as part of compliance mandates. FIM collects the
critical details needed to quickly identify changes and root out activity that violates policy or is potentially malicious. FIM helps customers to comply with
change control policy enforcement and change monitoring requirements.

Cloud Security

Qualys TotalCloud is a Cloud-Native Application Protection Platform (CNAPP), which provides an integrated suite of security capabilities designed
for multi-cloud environments. It provides complete visibility and cyber-risk exposure assessment across cloud assets, enabling continuous discovery and
monitoring of the cloud landscape to identify risks and maintain compliance. With its FlexScan technology, TotalCloud offers comprehensive assessment
features  that  include  no-touch,  agentless,  API,  and  snapshot-based  scanning,  along  with  agent  and  network-based  scanning  for  thorough  vulnerability
detection. The TruRisk component allows for a unified risk view, correlating vulnerabilities, security controls, and compliance across resources to prioritize
and  reduce  cyber  risks  effectively.  For  real-time  defense,  TotalCloud's  InstaProtect  continuously  monitors  all  cloud  assets  to  detect  and  protect  against
evolving and unknown threats. Remediation is streamlined through our QFlow technology, which provides no-code, drag-and-drop workflows for efficient
vulnerability  management.  TotalCloud  provides  organizations  with  an  all-encompassing  solution,  delivering  fast,  agentless,  real-time  security  and
compliance  across  a  variety  of  use  cases,  including  Cloud  Workload  Protection  (CWP),  Cloud  Detection  and  Response  (CDR),  Cloud  Security  Posture
Management  (CSPM),  Infrastructure  as  Code  (IaC),  and  Container  Security  (CS)  to  offer  organizations  a  single  unified  solution  for  comprehensively
securing their cloud and multi-cloud environments.

Free Services

We also offer organizations of all sizes free security and compliance services based on our cloud platform:
• Qualys Global AssetView app automatically creates a continuous, real-time inventory of known and unknown assets throughout a user's global
IT footprint across on-premises, endpoints, cloud, containers, and mobile environments. The app also automatically normalizes and categorizes
assets  to  ensure  clean,  reliable,  and  consistent  data.  In-depth  asset  details  provide  fine-grained  visibility  on  the  system,  services,  installed
software, network, and users. It also detects any device that connects to a user's networks, via passive scanning technology. Upon an unknown
device  detection,  users  can  install  a  light-weight  Qualys  self-updating  agent  (3MB)  to  turn  the  device  into  a  managed  device  or  launch  a
vulnerability scan.

• Qualys Certificate Inventory inventories and assesses all Internet-facing certificates to generate SSL/TLS configuration grades, identifies the
certificate issuer and tracks certificate expirations to help stop expired and expiring certificates from interrupting critical business functions.

Our Growth Strategy

We intend to strengthen our leadership position as a trusted provider of cloud-based IT, security and compliance solutions. The key elements of our

growth strategy are:

•

•

Continue  to  innovate  and  enhance  our  cloud  platform  and  suite  of  solutions.  We  intend  to  continue  to  make  significant  investments  in
research  and  development  to  extend  our  cloud  platform’s  functionality  by  developing  new  security  solutions  and  capabilities  and  further
enhancing our existing suite of solutions.

Expand the use of our suite of solutions by our large and diverse customer base. With more than 10,000 customers, across many industries
and geographies, we believe we have a significant opportunity to sell additional solutions to our customers and expand their use of our suite of
solutions. Because our customers typically initially deploy one or two of our solutions in select parts of their IT infrastructures, our existing
customers  serve  as  a  strong  source  of  new  sales  as  they  expand  their  scope  and  increase  their  subscriptions  or  choose  to  adopt  additional
solutions  from  our  integrated  suite  of  IT,  security  and  compliance  offerings.  In  this  regard,  we  continue  to  expand  our  sales  execution  and
marketing functions to increase adoption of our newly developed solutions among our existing customers.

• Drive  new  customer  growth  and  broaden  our  global  reach.  We  are  pursuing  new  customers  by  targeting  key  accounts,  releasing  free  IT,
security and compliance services and expanding both our sales and marketing organization and network of channel partners. We will continue
to  seek  to  make  significant  investments  to  encourage  organizations  to  replace  their  existing  security  products  with  our  cloud  solutions.  We
intend  to  expand  our  relationships  with  key  security  consulting  organizations,  leading  cloud  service  providers,  managed  security  service
providers and value-added resellers to accelerate the adoption of our cloud platform. We seek to strengthen existing relationships as well as
establish new relationships to increase the distribution and market awareness of our cloud platform and target new geographic regions. We also
plan to partner with such security providers that can host our private cloud offering within their shared cloud platforms, helping us expand our
reach in new markets and new geographies.

•

Selectively  pursue  technology  acquisitions  to  bolster  our  capabilities  and  leadership  position.  We  may  explore  acquisitions  that  are
complementary to and can expand the functionality of our cloud platform. We may also seek to acquire development teams to supplement our
own personnel and acquire technology to increase the breadth of our cloud-based IT, security and compliance solutions. In 2022, we acquired
certain intangible assets of Blue Hexagon Inc., enabling us to leverage our cloud platform with deep learning AI and machine learning (ML)
technologies to uncover behavior patterns including active vulnerability exploitation, identification of advanced network threats, and adaptive
risk mitigation across all assets and applications. In 2021, we acquired certain intangible assets of Kandor Soft Labs Private Ltd. (TotalCloud),
strengthening  our  cloud  security  solution  by  allowing  customers  to  build  user-defined  workflows  for  custom  policies  and  execute  them  on-
demand for simplified security and compliance.

Our Customers

We  market  and  sell  our  solutions  to  enterprises,  government  entities  and  small  and  medium-sized  businesses  across  a  broad  range  of  industries,
including education, financial services, government, healthcare, insurance, manufacturing, media, retail, technology and utilities. As of December 31, 2023,
we had over 10,000 customers worldwide, including a majority of the Forbes Global 100. In each of 2023, 2022 and 2021, no one customer accounted for
more than 10% of our revenues. In 2023, 2022 and 2021, 60%, 60% and 61%, respectively, of our revenues were derived from customers in the United
States based on our customers' billing addresses. We sell our solutions to enterprises and government entities primarily through our field sales force and to
small  and  medium-sized  businesses  through  our  inside  sales  force.  We  generate  a  significant  portion  of  sales  through  our  channel  partners,  including
managed security service providers, value-added resellers and consulting firms in the United States and internationally.

Sales and Marketing

Sales

We market and sell our IT, security and compliance solutions to customers directly through our sales teams as well as indirectly through our network

of channel partners.

Our global sales force is organized into a field sales team, which focuses on enterprises, generally including organizations with more than 5,000
employees,  and  an  inside  sales  team,  which  focuses  on  small  to  medium-sized  businesses,  which  generally  include  organizations  with  less  than  5,000
employees.  Both  our  field  and  inside  sales  teams  are  divided  into  three  geographic  regions,  the  Americas;  Europe,  Middle  East  and  Africa;  and  Asia-
Pacific. We also further assign each of our sales teams into groups that focus on adding new customers or managing relationships with existing customers.

11

Table of Contents

Our channel partners maintain relationships with their customers throughout the territories in which they operate and provide their customers with
services  and  third-party  solutions  to  help  meet  those  customers’  evolving  security  and  compliance  requirements.  As  such,  these  partners  offer  our  IT,
security and compliance solutions in conjunction with one or more of their own products or services and act as a conduit through which we can connect
with these prospective customers to offer our solutions. Our channel partners include security consulting organizations, leading cloud providers, managed
service providers and resellers.

For sales involving a channel partner, the channel partner engages with the prospective customer directly and involves our sales team as needed to
assist in developing and closing an order. When a channel partner secures a sale, we sell the associated subscription to the channel partner who in turn
resells  the  subscription  to  the  customer,  with  the  channel  partner  earning  a  fee  based  on  the  total  value  of  the  order.  Once  the  order  is  completed,  we
provide these customers with direct access to our solutions and other associated back-office applications, enabling us to establish a direct relationship as
part of ensuring customer satisfaction with our solutions. At the end of the subscription term, the channel partner engages with the customer to execute a
renewal  order,  with  our  sales  team  providing  assistance  as  required.  In  2023,  2022  and  2021,  43%,  42%  and  41%,  respectively,  of  our  revenues  were
generated by channel partners.

Marketing

Our marketing programs include a variety of online marketing, advertising, conferences, events, public relations activities and web-based seminar

campaigns targeted at key decision makers within our prospective customers.

We have a number of marketing initiatives to build awareness and encourage customer adoption of our solutions. We offer free trials and services to
allow prospective customers to experience the quality of our solutions, to learn in detail about the features and functionality of our cloud platform, and to
quantify the potential benefits of our solutions.

Customer Support

Qualys Support delivers 24x7x365 day customer technical support from global centers located in Foster City, California; Raleigh, North Carolina;
and Pune, India. We recruit senior level technical personnel and trained subject matter experts who work closely with engineering and operations personnel
to resolve issues quickly. Our IT, security and compliance solutions can be deployed easily and are designed to be implemented and operated without the
need  for  significant  professional  services.  We  also  offer  various  training  programs  as  part  of  our  subscriptions  to  all  of  our  customers.  In  addition,  we
leverage the insights drawn from our customers to further improve the functionality of our IT, security and compliance solutions. Our mission is to ensure
customer satisfaction and play a critical role in retaining and expanding our customer base.

Research and Development and Operations

We devote significant resources to maintain, enhance and add new functionality to our cloud platform and the integrated suite of solutions that we
offer. Our development organization consists of agile engineering teams with substantial security expertise in specific areas of our solutions. In addition to
our  development  teams,  we  also  built  a  sophisticated  research  team  focused  on  identifying  threats  and  developing  signatures  for  vulnerabilities  and
compliance  checks  so  that  we  can  provide  our  customers  with  daily  updates  and  enable  them  to  scan  their  assets  for  the  latest  threats.  We  conduct  our
research and development in the United States, France and India, which gives us access to some of the best research and engineering talent in the world.
Our focus remains to attract engineering talent as we continue to add new solutions and improve existing ones.

Our  development  team  works  closely  with  our  customers  and  partners  to  gain  valuable  insights  into  their  environments  and  gather  feedback  for
threat research, product development and innovations. We typically release updates to our solutions, including enhancements and new features multiple
times a year, and we measure the quality of our scan results on a frequent basis in an effort to maintain the highest level of scan accuracy.

The modular architecture of our cloud platform enables our engineering teams to simultaneously work on different features, accelerating the delivery
of new functionalities to customers. Our research and development team also works collaboratively with our technical support team to ensure customer
satisfaction and with our sales team to accelerate the adoption of our solutions.

Shared Cloud Platform Agreements

Our  shared  cloud  platform  operations  are  provided  by  large  third-party  vendors  and  are  located  in  the  United  States,  Canada,  Switzerland,  the
Netherlands, United Arab Emirates, Australia, United Kingdom, Italy, the Kingdom of Saudi Arabia and India. Our shared cloud platform agreements have
varying terms through 2027.

Table of Contents

Competition

The expanding capabilities of our IT, security and compliance solutions have enabled us to address a growing array of opportunities in the cloud IT,
security  and  compliance  market.  We  compete  with  a  large  and  broad  array  of  established  and  emerging  vulnerability  management  vendors,  compliance
vendors and data security vendors in a highly fragmented and competitive environment.

We compete with large and small public companies, such as Broadcom (Symantec Enterprise Security), CrowdStrike, Palo Alto Networks, Rapid7,
and  Tenable  Holdings,  as  well  as  privately  held  security  providers  including  Axonius,  Checkmarx,  Flexera,  Invicti,  Ivanti,  Tanium,  HelpSystems
(Tripwire),  Trustwave  Holdings,  Veracode  and  Wiz.  We  also  seek  to  replace  IT,  security  and  compliance  solutions  that  organizations  have  developed
internally. As we continue to extend our cloud platform’s functionality by further developing IT, security and compliance solutions, such as Cybersecurity
Asset Management and Patch Management, we expect to face additional competition in these new markets. Our competitors may also attempt to further
expand their presence in the IT, security and compliance market and compete more directly against one or more of our solutions.

We  believe  that  the  principal  competitive  factors  affecting  our  markets  include  product  functionality,  breadth  of  offerings,  flexibility  of  delivery
models,  ease  of  deployment  and  use,  total  cost  of  ownership,  scalability  and  performance,  customer  support  and  the  extensibility  of  our  platform.  We
believe that our suite of solutions generally competes favorably with respect to these factors. However, many of our primary competitors have greater name
recognition, longer operating histories, more established customer relationships, larger marketing budgets and significantly greater resources than we do.

Intellectual Property

We  rely  on  a  combination  of  trade  secrets,  copyrights,  patents  and  trademarks,  as  well  as  contractual  protections,  to  establish  and  protect  our
intellectual property rights and protect our proprietary technology. As of December 31, 2023, we have thirty-six issued patents, which expire from 2029 to
2042, several pending U.S. patent applications and an exclusive license to four U.S. patents. The inbound license remains in effect until the licensed patents
are no longer enforceable, unless the applicable license agreement is first terminated by us or terminated by the licensor for a breach of the agreement or if
we undergo certain bankruptcy events. The licenses are currently exclusive and will remain exclusive so long as we make an appropriately-timed written
election and pay an annual fixed royalty for ten years thereafter. These exclusive licenses are subject to the licensor’s reservation of certain rights in the
patents and subject to the U.S. government’s reserved rights in the technology. We have a number of registered and unregistered trademarks. We require our
employees, consultants and other third parties to enter into confidentiality and proprietary rights agreements and control access to software, documentation
and other proprietary information. We view our trade secrets and know-how as a significant component of our intellectual property assets, as we have spent
years designing and developing our cloud platform, which we believe differentiates us from our competitors.

We expect that software and other solutions in our industry may be subject to third-party infringement claims as the number of competitors grows
and the functionality of products in different industry segments overlaps. Any of these third parties might make a claim of infringement against us at any
time.

Human Capital Resources

We take a holistic approach to our human capital management strategy, striving to create a culture where talented people want to come to work,
develop  their  careers,  become  leaders,  and  make  a  difference  for  all  our  stakeholders  and  communities.  Doing  the  right  thing  for  our  people,  our
communities and our environment upholds the trust of our customers, partners, employees, and stockholders, enabling us to grow our business profitably
and meet the diverse needs of our constituents. As of December 31, 2023, we had 2,188 full-time employees, including 1,016 in research and development,
438 in sales and marketing, 504 in operations and customer support, and 230 in general and administrative. As of December 31, 2023, approximately 75%
of our employees were located outside of the United States, with 66% of our employees located in Pune, India. None of our U.S. employees are covered by
collective bargaining agreements. Employees in certain European countries and Brazil have collective bargaining arrangements at the national level. We
believe our employee relations are good, and we have not experienced any work stoppages.

Compensation and Benefits

Our  Competitive  Compensation  and  Benefits  Policy.  We  understand  that  providing  competitive  compensation  and  benefits  plays  a  critical  role  in
attracting and retaining the best available personnel. That is why we offer robust compensation and benefits to our employees, including competitive base
salaries,  variable  pay  and  equity  awards,  and  generous  benefits  packages.  To  support  the  health  and  wellness  of  our  workforce,  Qualys  offers  premium
health coverage with minimal out-of-pocket contributions for our employees.

Corporate Governance. Qualys maintains a Compensation and Talent Committee of the Board of Directors to oversee the company’s compensation
policies, plans and benefits programs, and overall compensation philosophy. The Committee approves CEO and executive officers’ compensation plans,
and reviews, approves, and administers various employee benefit plans, among other duties. As part of its ongoing review of the performance criteria and
compensation of designated key executives, the Compensation and Talent Committee also meets annually with the CEO, the Company’s principal human
resources executive, and any other corporate officers as it deems appropriate.

Supporting our Team and Community

Talent Development and Safety. We take a holistic approach to our social strategy, striving to create a culture where talented people want to come to
work,  develop  their  careers,  become  leaders,  and  make  a  difference  for  all  our  stakeholders  and  communities.  We  believe  every  employee  makes  a
difference, so we empower them in their roles and support them for professional growth. We assist employees in achieving their career goals by helping
them improve their skillsets and transition to increasingly challenging roles.

Diversity and Inclusion. We are proud to be a leader in the promotion and practice of diversity and inclusion. We take pride in our cultural diversity
with  offices  and  employees  all  over  the  world.  Our  objective  is  to  continue  to  improve  our  hiring,  development,  advancement,  and  retention  of  diverse
talent and to foster an inclusive environment. In addition to having more than 50% of the executive team from underrepresented communities, we are also
continuing to improve diversity among our growing workforce, with steady increases in recent years in the percentage of women employed among our
global workforce and with over half of our US-based employees from underrepresented communities.

Qualys is focused on building a pipeline of diverse candidates across all our job functions. We define diversity as underrepresented job seekers, like

women, minorities, people with disabilities, older workers, and LGBTQIA+ community members.

Qualys searches the globe for top talent in an effort to recruit and hire diverse individuals with a variety of skills, experiences, and backgrounds. Our
company holiday calendar includes events and festivals from many regions and religions, and we include diverse cultural initiatives throughout the year to
ensure employees feel represented.

Promoting a Healthy Work-life Balance. Qualys aims to maintain a healthy work-life balance and provide resources to support our employees’ mental
and  physical  well-being.  During  2022,  our  workforce  gradually  transitioned  into  a  hybrid  work  schedule,  which  resulted  in  a  significant  portion  of  our
workforce working either in-person on a part-time basis, or remotely on a permanent basis. During 2023, we continued to offer this hybrid work schedule
to our workforce. Our top priority remains providing support for our employees, partners, and customers. We are fortunate that the nature of our business
allows us to successfully operate in this dynamic hybrid environment. We believe that our hybrid policy will be a key enabler to support the broad needs of
critical on-site to remote employees.

Community Engagement. We value the communities that support our operations and have several company and employee-led initiatives to support the

communities in which we operate. In 2023, our efforts were centered on advancing education, gender equality, and environmental initiatives.

Training and Development

Employee Training. We  require  our  employees  and  managers  to  participate  in  myriad  training  programs  directed  at  maintaining  a  harassment-free,
diverse, and secure workplace. With our diverse employee population, we uphold the rights to work in an environment that promotes equal opportunity and
prohibits discriminatory practices against race, color, national origin, ancestry, medical condition, religious creed (including religious dress and grooming
practices), marital status, registered domestic partner status, sex, sexual orientation, gender identity and expression, genetic characteristics and information,
age, veteran status,

14

Table of Contents

or any other protected characteristic. Creating a respectful workplace and preventing harassment to our employees remain our on-going commitment.

Employee Development. Investing in employees is critical to our success. Qualys employees participate in an onboarding program to integrate new
hires into role-specific functions and company culture. Qualys offers managers and employees various training courses as needed. To support career growth
inside  and  outside  Qualys,  we  offer  free  self-paced  and  instructor-led  certified  training  on  core  Qualys  topics,  giving  employees  and  non-employees  an
opportunity to achieve certifications and job-related courses free of charge.

To allow for open dialogue between employees and managers, we conduct formal employee reviews each year. Corrective action plans are developed
for  employees  who  may  be  struggling  to  meet  his  or  her  job  responsibilities.  Employee  performance  is  considered  during  compensation  reviews.  In
addition to formal reviews, our Human Resources team regularly meets with managers to check in with teams and conducts exit interviews globally. Qualys
India also conducts an assimilation program for new employees, through which feedback is collected as employees join the company.

Sustainable Business Operations

Our  Sustainable  Solutions.  Qualys  products,  delivered  via  our  multi-tenant  cloud  platform,  enable  improved  environmental  sustainability  for  our
customers. In particular, our cloud-based solutions minimize the number of physical servers our customers have to deploy within their own environments,
reducing  energy  consumption  on  their  end.  Qualys  Cloud  Apps,  delivering  rich  content  and  dashboards  visible  on  any  device,  also  reduce  paper  and
printing costs for our customers.

Our Eco-Friendly Operations. Our environmental, health and safety systems, processes and tools in place across our footprint enable Qualys to meet
or exceed governmental and industry requirements. We strive to consistently improve how we operate our platforms in energy-efficient networks and data
centers  as  well  as  pursue  sustainability  initiatives  that  reduce  energy,  waste  and  materials  consumption.  We  have  14  multi-tenant  platforms  across  the
world, eight of which are in collocated facilities. The others are hosted in public cloud environments. Though data centers are inherently energy-intensive,
utilizing collocated facilities allows us to leverage economies of scale for power and cooling. In addition, most of our third-party providers continue to
advance their own sustainability programs to reduce their environmental impact.

Environmental Standards Within Supply Chain. We are committed to advancing supply chain responsibility and strive to enhance transparency and
promote  greater  accountability  in  our  own  operations  and  with  our  suppliers.  Qualys  outsources  product  manufacturing  and  recycling  to  suppliers  and
vendors that follow the highest environmental standards in the industry, such as ISO 14001. We also seek to prohibit our suppliers from profiting from the
sale  of  tantalum,  tin,  tungsten,  and  gold  (also  known  as  “conflict  minerals”)  that  funds  conflict  in  the  Democratic  Republic  of  the  Congo  (DRC)  and
adjoining countries, and we seek to require that our suppliers source these minerals from socially responsible suppliers.

our  ability  to  integrate  any  products  or  services  that  we  have  acquired  or  may  acquire  in  the  future  into  our  product  suite  or  migrate  existing
customers of any companies that we have acquired or may acquire in the future to our products and services;

future accounting pronouncements or changes in our accounting policies;

our effective tax rate, changes in tax rules, tax effects of infrequent or unusual transactions, and tax audit settlements;

the amount and timing of income tax that we recognize resulting from stock-based compensation;

the timing of expenses related to the development or acquisition of technologies, services or businesses; and

potential goodwill and intangible asset impairment charges associated with acquired businesses.

Further, the interpretation and application of international laws and regulations in many cases is uncertain, and our legal and regulatory obligations in
foreign jurisdictions are subject to frequent and unexpected changes, including the potential for various regulatory or other governmental bodies to enact
new or additional laws or regulations or to issue rulings that invalidate prior laws or regulations.

Each  factor  above  or  discussed  elsewhere  in  this  Annual  Report  on  Form  10-K  or  the  cumulative  effect  of  some  of  these  factors  may  result  in
fluctuations in our operating results. This variability and unpredictability could result in our failure to meet expectations with respect to operating results, or
those of securities analysts or investors, for a particular period. In addition, a significant percentage of our operating expenses are fixed in nature and based
on forecasted trends in revenues. Accordingly, in the event of shortfalls in revenues, we are generally unable to mitigate the negative impact on margins in
the short term by reducing our operating expenses. If we fail to meet or exceed expectations for our operating results for these or any other reasons, the
trading price of our common stock could fall and we could face costly lawsuits, including securities class action suits.

If we do not successfully anticipate market needs and opportunities or are unable to enhance our solutions and develop new solutions that meet those
needs and opportunities on a timely or cost-effective basis, we may not be able to compete effectively and our business and financial condition may be
harmed.

The IT, security and compliance market is characterized by rapid technological advances, customer price sensitivity, short product and service life
cycles, intense competition, changes in customer requirements, frequent new product introductions and enhancements and evolving industry standards and
regulatory mandates. Any of these factors could create downward pressure on pricing and gross margins, and could adversely affect our renewal rates, as
well as our ability to attract new customers. Our future success will depend on our ability to enhance existing solutions, introduce new solutions on a timely
and  cost-effective  basis,  meet  changing  customer  needs,  extend  our  core  technology  into  new  applications,  and  anticipate  and  respond  to  emerging
standards  and  business  models.  We  must  also  continually  change  and  improve  our  solutions  in  response  to  changes  in  operating  systems,  application
software, computer and communications hardware, networking software, shared cloud platform infrastructures, programming tools and computer language
technology.

We  may  not  be  able  to  anticipate  future  market  needs  and  opportunities  or  develop  enhancements  or  new  solutions  to  meet  such  needs  or
opportunities in a timely manner or at all. The market for cloud solutions for IT, security and compliance continues to evolve, and it is uncertain whether
our new solutions will gain market acceptance.

Our solution enhancements or new solutions could fail to attain sufficient market acceptance for many reasons, including:

•

•

•

•

•

•

•

•

•

•

failure to timely meet market demand for product functionality;

inability to identify and provide intelligence regarding the attacks or techniques used by cyber-attackers;

inability to inter-operate effectively with the database technologies, file systems or web applications of our prospective customers;

defects, errors or failures;

delays in releasing our enhancements or new solutions;

negative publicity about their performance or effectiveness;

introduction or anticipated introduction of products by our competitors;

poor business conditions, causing customers to delay IT, security and compliance purchases;

easing or changing of external regulations related to IT, security and compliance; and

reluctance of customers to purchase cloud solutions for IT, security and compliance.

Furthermore, diversifying our solutions and expanding into new IT, security and compliance markets will require significant investment and planning,
require  that  our  research  and  development  and  sales  and  marketing  organizations  develop  expertise  in  these  new  markets,  bring  us  more  directly  into
competition with IT, security compliance providers that may be better established or have greater resources than we do, require additional investment of
time and resources in the development and training of our channel partners and entail significant risk of failure.

If we fail to anticipate market requirements or fail to develop and introduce solution enhancements or new solutions to satisfy those requirements in a

timely manner, such failure could substantially decrease or delay market acceptance and sales of our

17

Table of Contents

present and future solutions and cause us to lose existing customers or fail to gain new customers, which would significantly harm our business, financial
condition and results of operations.

If  we  fail  to  continue  to  effectively  scale  and  adapt  our  platform  to  meet  the  performance  and  other  requirements  of  our  customers,  our  operating
results and our business would be harmed.

Our future growth depends to a significant extent on our ability to continue to meet the expanding needs of our customers as their use of our cloud
platform grows. As these customers gain more experience with our solutions, the number of users and the number of locations where our solutions are
being accessed may expand rapidly in the future. In order to ensure that we meet the performance and other requirements of our customers, we intend to
continue to make significant investments to develop and implement new proprietary and third-party technologies at all levels of our cloud platform. These
technologies, which include databases, applications and server optimizations, and network and hosting strategies, are often complex, new and unproven.
We  may  not  be  successful  in  developing  or  implementing  these  technologies.  To  the  extent  that  we  do  not  effectively  scale  our  platform  to  maintain
performance as our customers expand their use of our platform, our operating results and our business may be harmed.

If we are unable to renew existing subscriptions for our IT, security and compliance solutions, sell additional subscriptions for our solutions and attract
new customers, our operating results would be harmed.

We offer our cloud platform and integrated suite of solutions pursuant to a software-as-a-service model, and our customers purchase subscriptions
from us that are generally one year in length. Our customers have no obligation to renew their subscriptions after their subscription period expires, and they
may not renew their subscriptions at the same or higher levels or at all. As a result, our ability to grow depends in part on customers renewing their existing
subscriptions  and  purchasing  additional  subscriptions  and  solutions.  Our  customers  may  choose  not  to  renew  their  subscriptions  to  our  solutions  or
purchase additional solutions due to a number of factors, including their satisfaction or dissatisfaction with our solutions, the prices of our solutions, the
prices of products or services offered by our competitors, reductions in our customers’ spending levels due to the macroeconomic environment or other
factors.  If  our  customers  do  not  renew  their  subscriptions  to  our  solutions,  renew  on  less  favorable  terms,  or  do  not  purchase  additional  solutions  or
subscriptions, our revenues may grow more slowly than expected or decline and our operating results would be harmed.

In addition, our future growth depends in part upon increasing our customer base. Our ability to achieve significant growth in revenues in the future
will depend, in large part, upon continually attracting new customers and obtaining subscription renewals to our solutions from those customers. If we fail
to attract new customers, our revenues may grow more slowly than expected and our operating results would be harmed.

Our current research and development efforts may not produce successful products or enhancements to our platform that result in significant revenue,
cost savings or other benefits in the near future.

We must continue to dedicate significant financial and other resources to our research and development efforts if we are to maintain our competitive
position. However, developing products and enhancements to our platform is expensive and time consuming, and there is no assurance that such activities
will result in significant new marketable products or enhancements to our platform, design improvements, cost savings, revenue or other expected benefits.
If we spend significant resources on research and development and are unable to generate an adequate return on our investment, our business and results of
operations may be materially and adversely affected.

Our  platform,  website  and  internal  systems  may  be  subject  to  intentional  disruption  or  other  security  incidents  that  could  result  in  liability  and
adversely impact our reputation and future sales.

We and our service providers face threats from a variety of sources, including attacks on our networks and systems from numerous sources, including
traditional  “hackers,”  sophisticated  nation-state  and  nation-state  supported  actors,  other  sources  of  malicious  code  (such  as  viruses  and  worms),
ransomware, social engineering, denial of service attacks, and phishing attempts. We and our service providers could be a target of cyber-attacks or other
malfeasance  designed  to  impede  the  performance  of  our  solutions,  penetrate  our  network  security  or  the  security  of  our  cloud  platform  or  our  internal
systems,  misappropriate  proprietary  information  and/or  cause  interruptions  to  our  services.  We  and  our  service  providers  have  experienced  and  may
continue to experience security incidents and attacks of varying degrees from time to time. We have incurred costs to respond to such incidents and may
continue to incur costs to support our efforts to enhance our security measures. Additionally, due to political uncertainty and military actions in parts of
Eastern Europe and the Middle East, we and our service providers are vulnerable to heightened

18

Table of Contents

risks of cybersecurity incidents and security and privacy breaches from or affiliated with nation-state actors, including attacks that could materially disrupt
our systems, operations and services.

Our  solutions,  platforms,  and  system,  and  those  of  our  service  providers,  may  also  suffer  security  incidents  as  a  result  of  non-technical  issues,
including intentional or inadvertent acts or omissions by our employees or service providers. With the increase in personnel working remotely, we and our
service providers are at increased risk for security breaches and incidents. We have taken and intend to continue to take steps to monitor and enhance the
security of our solutions, cloud platform, and other relevant systems, IT infrastructure, networks, and data; however, the unprecedented scale of remote
work may require additional personnel and resources, which nevertheless cannot be guaranteed to fully safeguard our solutions, our cloud platform, or any
systems, IT infrastructure networks, or data upon which we rely. Further, because our operations involve providing IT security solutions to our customers,
we  may  be  targeted  for  cyber-attacks  and  other  security  incidents.  A  breach  in  or  incident  impacting  our  data  security,  an  attack  against  our  service
availability, or any breach, incident, or attack impacting our third-party service providers, could impact our networks or networks secured by our solutions,
creating system disruptions or slowdowns and exploiting security vulnerabilities of our solutions, and the information stored on our networks or those of
our  third-party  service  providers  could  be  accessed,  used,  publicly  disclosed,  altered,  lost,  or  stolen,  which  could  subject  us  to  liability  and  cause  us
financial harm. If an actual or perceived disruption in the availability of our solutions or the breach or other compromise of our security measures or those
of our service providers occurs, it could adversely affect the market perception of our solutions, result in a loss of competitive advantage, have a negative
impact  on  our  reputation,  or  result  in  the  loss  of  customers,  channel  partners  and  sales,  and  it  may  expose  us  to  the  loss,  unavailability  or  alteration  of
information, claims, demands and litigation, regulatory investigations, actions and other proceedings and possible liability. Any such actual or perceived
security breach or incident or disruption could also divert the efforts of our technical and management personnel. We and our service providers may face
difficulties or delays in identifying and responding to any security breach or incident. We also may incur significant costs and operational consequences of
investigating, remediating, eliminating and putting in place additional tools and devices designed to prevent actual or perceived security incidents, as well
as costs to respond to and otherwise address any breach or incident, including any to comply with any notification obligations resulting from any security
incidents. In addition, any such actual or perceived security breach or incident could impair our ability to operate our business and provide solutions to our
customers. If this happens, our reputation could be harmed, our revenues could decline and our business could suffer.

Although we maintain insurance coverage that may be applicable to certain liabilities in the event of a security breach or other security incident, we
cannot be certain that our insurance coverage will be adequate for liabilities that actually are incurred, that insurance will continue to be available to us on
economically reasonable terms, or at all, or that any insurer will not deny coverage as to any future claim. The successful assertion of one or more large
claims  against  us  that  exceed  available  insurance  coverage  or  the  occurrence  of  changes  in  our  insurance  policies,  including  premium  increases  or  the
imposition of large deductible or co-insurance requirements, could have a material and adverse effect on our business, including our financial condition,
operating results and reputation.

Our sales cycle can be long and unpredictable, and our sales efforts require considerable time and expense. As a result, revenues may vary from period
to period, which may cause our operating results to fluctuate and could harm our business.

The  timing  of  sales  of  subscriptions  for  our  solutions  can  be  difficult  to  forecast  because  of  the  length  and  unpredictability  of  our  sales  cycle,
particularly  with  large  transactions  and  in  the  current  macroeconomic  environment.  We  sell  subscriptions  to  our  IT,  security  and  compliance  solutions
primarily  to  IT  departments  that  are  managing  a  growing  set  of  user  and  compliance  demands,  which  has  increased  the  complexity  of  customer
requirements to be met and confirmed during the sales cycle and prolonged our sales cycle. Further, the length of time that potential customers devote to
their testing and evaluation, contract negotiation and budgeting processes varies significantly, which has also made our sales cycle long and unpredictable.
The length of the sales cycle for our solutions typically ranges from six to twelve months but can be more than eighteen months. In addition, we might
devote substantial time and effort to a particular unsuccessful sales effort, and as a result we could lose other sales opportunities or incur expenses that are
not offset by an increase in revenues, which could harm our business.

Adverse economic conditions or reduced IT spending may adversely impact our business.

Our  business  depends  to  a  significant  extent  on  the  overall  demand  for  IT  and  on  the  economic  health  of  our  current  and  prospective  customers.
Economic weakness, customer financial difficulties, supply chain constraints, change in interest rates, inflationary pressures and potential for a recession,
and constrained spending on IT security, as well as longer sales cycles, which factors we have experienced in 2023, have resulted and may in the future
result in decreased revenue and earnings. Such factors have made and could in the future make it difficult to accurately forecast our sales and operating
results and could negatively affect our ability to provide accurate forecasts to our contract manufacturers. In addition, continued governmental budgetary
challenges in the United States and Europe, inflationary pressures and potential for a recession, and geopolitical turmoil in many parts of the

19

Table of Contents

world, including the ongoing military conflicts in parts of Eastern Europe and the Middle East, and other disruptions to global and regional economies and
markets in many parts of the world, as well as uncertainties related to changes in public policies such as domestic and international regulations, taxes or
international trade agreements, have and may continue to put pressure on global economic conditions and overall spending on IT security and may further
increase inflation, both in the U.S. and globally, which could increase our operating costs in the future and reduce overall spending on IT security. General
economic  weakness  may  also  lead  to  longer  collection  cycles  for  payments  due  from  our  customers,  an  increase  in  customer  bad  debt,  restructuring
initiatives  and  associated  expenses,  and  impairment  of  investments.  Furthermore,  the  continued  weakness  and  uncertainty  in  worldwide  credit  markets,
including the sovereign debt situation in certain countries in the European Union, may adversely impact our European operations, as well as our current and
potential customers' available budgetary spending, which could lead to delays or reductions in planned purchases of our solutions.

Uncertainty  about  future  economic  conditions  also  makes  it  difficult  to  forecast  operating  results  and  to  make  decisions  about  future  investments.
Future or continued economic weakness for us or our customers, failure of our customers and markets to recover from such weakness, customer financial
difficulties, and reductions in spending on IT security could have a material adverse effect on demand for our platform and consequently on our business,
financial condition and results of operations.

Our IT, security and compliance solutions are delivered from 14 shared cloud platforms, and any disruption of service at these facilities would interrupt
or delay our ability to deliver our solutions to our customers which could reduce our revenues and harm our operating results.

We  currently  host  substantially  all  of  our  solutions  from  third-party  shared  cloud  platforms  located  in  the  United  States,  Canada,  Switzerland,  the
Netherlands, United Arab Emirates, Australia, United Kingdom, Italy, the Kingdom of Saudi Arabia and India. These facilities are vulnerable to damage or
interruption  from  earthquakes,  hurricanes,  floods,  fires,  cybersecurity  attacks,  terrorist  attacks,  employee  negligence,  power  losses,  telecommunications
failures and similar events. The facilities also could be subject to break-ins, sabotage, intentional acts of vandalism and other misconduct. The occurrence
of a natural disaster, an act of terrorism or misconduct, a decision to close the facilities without adequate notice or other unanticipated problems could result
in interruptions in our services.

Some  of  our  shared  cloud  platforms  are  not  currently  redundant  and  we  may  not  be  able  to  rapidly  move  our  customers  from  one  shared  cloud
platform to another, which may increase delays in the restoration of our service for our customers if an adverse event occurs. We have added shared cloud
platforms to provide additional capacity and to enable disaster recovery. We continue to build out these facilities; however, these additional facilities may
not be operational in the anticipated time-frame and we may incur unplanned expenses.

Additionally, our existing shared cloud platform providers have no obligations to renew their agreements with us on commercially reasonable terms,
or  at  all.  If  we  are  unable  to  renew  our  agreements  with  the  facilities  providers  on  commercially  reasonable  terms  or  if  in  the  future  we  add  additional
shared cloud platform providers, we may experience costs or downtime in connection with the loss of an existing facility or the transfer to, or addition of,
new facilities.

Any  disruptions  or  other  performance  problems  with  our  solutions  could  harm  our  reputation  and  business  and  may  damage  our  customers’
businesses. Interruptions in our service delivery might reduce our revenues, cause us to issue credits to customers, subject us to potential liability and cause
customers to terminate their subscriptions or not renew their subscriptions.

We face competition in our markets, and we may lack sufficient financial or other resources to maintain or improve our competitive position.

We compete with a large range of established and emerging vulnerability management vendors, compliance vendors and data security vendors in a
highly fragmented and competitive environment. We face significant competition for each of our solutions from companies with broad product suites and
greater name recognition and resources than we have, as well as from small companies focused on specialized security solutions.

We compete with large and small public companies, such as Broadcom (Symantec Enterprise Security), CrowdStrike, Palo Alto Networks, Rapid7,
Tenable Holdings, as well as privately held security providers including Axonius, Checkmarx, Flexera, Invicti, Ivanti, Tanium, HelpSystems (Tripwire),
Trustwave Holdings, Veracode and Wiz. We also seek to replace IT, security and compliance solutions that organizations have developed internally. As we
continue  to  extend  our  cloud  platform’s  functionality  by  further  developing  IT,  security  and  compliance  solutions,  such  as  Cybersecurity  Asset
Management and Patch Management, we expect to face additional competition in these new markets. Our competitors may also attempt to further expand
their presence in the IT, security and compliance market and compete more directly against one or more of our solutions.

20

Table of Contents

We  believe  that  the  principal  competitive  factors  affecting  our  markets  include  product  functionality,  breadth  of  offerings,  flexibility  of  delivery
models, ease of deployment and use, total cost of ownership, scalability and performance, customer support and the extensibility of our platform. Many of
our existing and potential competitors have competitive advantages, including:

•

•

•

•

•

•

•

•

•

greater brand name recognition;

larger sales and marketing budgets and resources;

broader distribution networks and more established relationships with distributors and customers;

access to larger customer bases;

greater customer support resources;

greater resources to make acquisitions;

greater resources to develop and introduce products that compete with our solutions;

greater resources to meet relevant regulatory requirements; and

substantially greater financial, technical and other resources.

As  a  result,  our  competitors  may  be  able  to  respond  more  quickly  and  effectively  than  we  can  to  new  or  changing  opportunities,  technologies,
standards  or  customer  requirements.  With  the  introduction  of  new  technologies,  the  evolution  of  our  service  and  new  market  entrants,  we  expect
competition to intensify in the future.

In addition, some of our larger competitors have substantially broader product offerings and can bundle competing products and services with other
software  offerings.  As  a  result,  customers  may  choose  a  bundled  product  offering  from  our  competitors,  even  if  individual  products  have  more  limited
functionality than our solutions. These competitors may also offer their products at a lower price as part of this larger sale, which could increase pricing
pressure  on  our  solutions  and  cause  the  average  sales  price  for  our  solutions  to  decline.  These  larger  competitors  are  also  often  in  a  better  position  to
withstand any significant reduction in capital spending and will therefore not be as susceptible to economic downturns.

Furthermore, our current and potential competitors may establish cooperative relationships among themselves or with third parties that may further
enhance their resources and product and services offerings in the markets we address. In addition, current or potential competitors may be acquired by third
parties with greater available resources. As a result of such relationships and acquisitions, our current or potential competitors might be able to adapt more
quickly  to  new  technologies  and  customer  needs,  devote  greater  resources  to  the  promotion  or  sale  of  their  products  and  services,  initiate  or  withstand
substantial price competition, take advantage of other opportunities more readily or develop and expand their product and service offerings more quickly
than we do. For all of these reasons, we may not be able to compete successfully against our current or future competitors.

The sales prices of our solutions are subject to competitive pressures and may decrease, which may reduce our gross profits and adversely impact our
financial results.

The sales prices for our solutions may decline for a variety of reasons, including competitive pricing pressures, discounts, a change in our mix of
solutions and subscriptions, anticipation of the introduction of new solutions or subscriptions, or promotional programs. Competition continues to increase
in the market segments in which we participate, and we expect competition to further increase in the future, thereby leading to increased pricing pressures.
Larger competitors with more diverse product and service offerings may reduce the price of products or subscriptions that compete with ours or may bundle
them  with  other  products  and  subscriptions.  Additionally,  although  we  price  our  products  and  subscriptions  worldwide  in  U.S.  Dollars,  Euro,  British
Pounds, Canadian Dollars, Japanese Yen and Indian Rupee, currency fluctuations in certain countries and regions may negatively impact actual prices that
partners and customers are willing to pay in those countries and regions, or the effective prices we realize in our reporting currency. We cannot assure you
that  we  will  be  successful  in  developing  and  introducing  new  offerings  with  enhanced  functionality  on  a  timely  basis,  or  that  our  new  product  and
subscription offerings, if introduced, will enable us to maintain our prices and gross profits at levels that will allow us to maintain positive gross margins
and profitability.

If  our  solutions  fail  to  help  our  customers  achieve  and  maintain  compliance  with  regulations  and  industry  standards,  our  revenues  and  operating
results could be harmed.

We  generate  a  portion  of  our  revenues  from  solutions  that  help  organizations  achieve  and  maintain  compliance  with  regulations  and  industry
standards. For example, many of our customers subscribe to our IT, security and compliance solutions to help them comply with the security standards
developed and maintained by the Payment Card Industry Security Standards Council,

21

Table of Contents

or  the  PCI  Council,  which  apply  to  companies  that  store  cardholder  data.  Industry  organizations  like  the  PCI  Council  may  significantly  change  their
security standards with little or no notice, including changes that could make their standards more or less onerous for businesses. Governments may also
adopt new laws or regulations, or make changes to existing laws or regulations, which could impact the demand for or value of our solutions.

If  we  are  unable  to  adapt  our  solutions  to  changing  regulatory  standards  in  a  timely  manner,  or  if  our  solutions  fail  to  assist  with  or  expedite  our
customers’ compliance initiatives, our customers may lose confidence in our solutions and could switch to products offered by our competitors. In addition,
if  regulations  and  standards  related  to  data  security,  vulnerability  management  and  other  IT,  security  and  compliance  requirements  are  relaxed  or  the
penalties  for  non-compliance  are  changed  in  a  manner  that  makes  them  less  onerous,  our  customers  may  view  government  and  industry  regulatory
compliance as less critical to their businesses, and our customers may be less willing to purchase our solutions. In any of these cases, our revenues and
operating results could be harmed.

If  our  solutions  fail  to  detect  vulnerabilities  or  incorrectly  detect  vulnerabilities,  our  brand  and  reputation  could  be  harmed,  which  could  have  an
adverse effect on our business and results of operations.

If  our  solutions  fail  to  detect  vulnerabilities  in  our  customers’  IT  infrastructures,  or  if  our  solutions  fail  to  identify  and  respond  to  new  and
increasingly complex methods of attacks, our business and reputation may suffer. There is no guarantee that our solutions will detect all vulnerabilities.
Additionally, our IT, security and compliance solutions may falsely detect vulnerabilities or threats that do not actually exist. For example, some of our
solutions rely on information on attack sources aggregated from third-party data providers who monitor global malicious activity originating from a variety
of sources, including anonymous proxies, specific IP addresses, botnets and phishing sites. If the information from these data providers is inaccurate, the
potential for false indications of security vulnerabilities increases. These false positives, while typical in the industry, may impair the perceived reliability
or usability of our solutions and may therefore adversely impact market acceptance of our solutions and could result in negative publicity, loss of customers
and sales, increased costs to remedy any incorrect information or problem, or claims by aggrieved parties. Similar issues may be generated by the misuse of
our tools to identify and exploit vulnerabilities.

Further, our solutions sometimes are tested against other security products, and may fail to perform as effectively, or to be perceived as performing as
effectively, as competitive products for any number of reasons, including misconfiguration. To the extent current or potential customers, channel partners,
or  others  believe  there  has  been  an  occurrence  of  an  actual  or  perceived  failure  of  our  solutions  to  detect  a  vulnerability  or  otherwise  to  function  as
effectively as competitive products in any particular test, or indicates our solutions do not provide significant value, our business, competitive position, and
reputation could be harmed.

In addition, our solutions do not currently extend to cover all mobile and personal devices that employees may bring into an organization. As such,
our solutions would not identify or address vulnerabilities in all mobile and personal devices, and our customers’ IT infrastructures may be compromised
by attacks that infiltrate their networks through such devices.

An actual or perceived security breach or incident or loss, theft, unavailability or other compromise of the sensitive data of one of our customers,

regardless of whether the breach is attributable to the failure of our solutions, could adversely affect the market’s perception of our security solutions.

If we are unable to continue the expansion of our sales force, sales of our solutions and the growth of our business would be harmed.

We  believe  that  our  growth  will  depend,  to  a  significant  extent,  on  our  success  in  recruiting  and  retaining  a  sufficient  number  of  qualified  sales
personnel and their ability to obtain new customers, manage our existing customer base and expand the sales of our newer solutions. We plan to continue to
expand our sales force and invest in our sales and marketing activities. Our recent hires and planned hires may not become as productive as quickly as we
would  like,  and  we  may  be  unable  to  hire  or  retain  sufficient  numbers  of  qualified  individuals  in  the  future  in  the  competitive  markets  where  we  do
business. Competition for highly skilled personnel is frequently intense and we may not be able to compete for these employees. If we are unable to recruit
and retain a sufficient number of productive sales personnel, sales of our solutions and the growth of our business may be harmed. Additionally, if our
efforts  do  not  result  in  increased  revenues,  our  operating  results  could  be  negatively  impacted  due  to  the  upfront  operating  expenses  associated  with
expanding our sales force.

22

Table of Contents

We  rely  on  third-party  channel  partners  to  generate  a  substantial  amount  of  our  revenues,  and  if  we  fail  to  expand  and  manage  our  distribution
channels, our revenues could decline and our growth prospects could suffer.

Our  success  significantly  depends  to  a  significant  extent  on  establishing  and  maintaining  relationships  with  a  variety  of  channel  partners  and  we
anticipate that we will continue to depend on these partners in order to grow our business. For the years ended December 31, 2023, 2022 and 2021, we
derived approximately 43%, 42% and 41% of our revenues from sales of subscriptions for our solutions through channel partners, and the percentage of
revenues derived from channel partners may increase in future periods. Our agreements with our channel partners are generally non-exclusive and do not
prohibit them from working with our competitors or offering competing solutions, and many of our channel partners have more established relationships
with  our  competitors.  If  our  channel  partners  choose  to  place  greater  emphasis  on  products  of  their  own  or  those  offered  by  our  competitors,  do  not
effectively market and sell our solutions, or fail to meet the needs of our customers, then our ability to grow our business and sell our solutions may be
adversely affected. In addition, the loss of one or more of our larger channel partners, who may cease marketing our solutions with limited or no notice, and
our possible inability to replace them, could adversely affect our sales. Moreover, our ability to expand our distribution channels depends in part on our
ability to educate our channel partners about our solutions, which can be complex. Our failure to recruit additional channel partners, or any reduction or
delay in their sales of our solutions or conflicts between channel sales and our direct sales and marketing activities may harm our results of operations.
Even if we are successful, these relationships may not result in greater customer usage of our solutions or increased revenues.

In  addition,  the  financial  health  of  our  channel  partners  and  our  continuing  relationships  with  them  are  important  to  our  success.  Some  of  these
channel  partners  may  be  unable  to  withstand  adverse  changes  in  economic  conditions,  which  could  result  in  insolvency  and/or  the  inability  of  such
distributors to obtain credit to finance purchases of our products and services. In addition, weakness in the end-user market could negatively affect the cash
flows of our channel partners who could, in turn, delay paying their obligations to us, which would increase our credit risk exposure. Our business could be
harmed  if  the  financial  condition  of  some  of  these  channel  partners  substantially  weakened  and  we  were  unable  to  timely  secure  replacement  channel
partners.

A significant portion of our customers, channel partners and employees are located outside of the United States, which subjects us to a number of risks
associated with conducting international operations, and if we are unable to successfully manage these risks, our business and operating results could
be harmed.

We market and sell subscriptions to our solutions throughout the world and have personnel in many parts of the world. In addition, we have sales
offices and research and development facilities outside the United States and we conduct, and expect to continue to conduct, a significant amount of our
business with organizations that are located outside the United States, particularly in Europe and Asia. Therefore, we are subject to risks associated with
having international sales and worldwide operations, including:

•

•

•

•

•

•

•

•

•

•

•

•

foreign currency exchange fluctuations;

trade and foreign exchange restrictions;

economic or political instability in foreign markets, including as a result of increasing tensions between India and China;

greater difficulty in enforcing contracts, accounts receivable collection and longer collection periods;

changes in regulatory requirements;

tax laws (including U.S. taxes on foreign subsidiaries);

difficulties and costs of staffing and managing foreign operations;

the uncertainty and limitation of protection for intellectual property rights in some countries;

costs of compliance with foreign laws and regulations and the risks and costs of non-compliance with such laws and regulations;

costs of complying with U.S. laws and regulations for foreign operations, including the Foreign Corrupt Practices Act, import and export control
laws,  tariffs,  trade  barriers,  economic  sanctions  and  other  regulatory  or  contractual  limitations  on  our  ability  to  sell  our  solutions  in  certain
foreign markets, and the risks and costs of non-compliance;

heightened risks of unfair or corrupt business practices in certain geographies and of improper or fraudulent sales arrangements that may impact
financial results and result in restatements of, and irregularities in, financial statements;

the potential for political unrest, acts of terrorism, hostilities or war;

• management communication and integration problems resulting from cultural differences and geographic dispersion; and

• multiple and possibly overlapping tax structures.

Some  of  our  business  partners  also  have  international  operations  and  are  subject  to  the  risks  described  above.  Even  if  we  are  able  to  successfully
manage the risks of international operations, our business may be adversely affected if our business partners are not able to successfully manage these risks.

Our business, including the sales of subscriptions of our solutions, may be subject to foreign governmental regulations, which vary substantially from
country to country and change from time to time. Failure to comply with these regulations could adversely affect our business. Further, in many foreign
countries it is common for others to engage in business practices that are prohibited by our internal policies and procedures or U.S. regulations applicable
to us. Although we have implemented policies and procedures designed to ensure compliance with these laws and policies, there can be no assurance that
all of our employees, contractors, channel partners and agents have complied or will comply with these laws and policies. Violations of laws or key control
policies by our employees, contractors, channel partners or agents could result in delays in revenue recognition, financial reporting misstatements, fines,
penalties  or  the  prohibition  of  the  importation  or  exportation  of  our  solutions  and  could  have  a  material  adverse  effect  on  our  business  and  results  of
operations.  If  we  are  unable  to  successfully  manage  the  challenges  of  international  operations,  our  business  and  operating  results  could  be  adversely
affected.

In addition, as of December 31, 2023, approximately 75% of our employees were located outside of the United States, with 66% of our employees
located in Pune, India. Accordingly, we are exposed to changes in laws governing our employee relationships in various U.S. and foreign jurisdictions,
including  laws  and  regulations  regarding  wage  and  hour  requirements,  fair  labor  standards,  employee  data  privacy,  unemployment  tax  rates,  workers’
compensation  rates,  citizenship  requirements  and  payroll  and  other  taxes  which  may  have  a  direct  impact  on  our  operating  costs.  We  may  continue  to
expand our international operations and international sales and marketing activities. Expansion in international markets has required, and will continue to
require, significant management attention and resources. We may be unable to scale our infrastructure effectively or as quickly as our competitors in these
markets and our revenues may not increase to offset any increased costs and operating expenses, which would cause our results to suffer.

We are exposed to fluctuations in currency exchange rates, which could negatively affect our financial condition and results of operations.

Our reporting currency is the U.S. dollar and we generate a majority of our revenues in U.S. dollars. However, for the year ended December 31, 2023,
we  incurred  approximately  29%  of  our  expenses  in  foreign  currencies,  primarily  Euro,  British  Pounds,  and  Indian  Rupee,  principally  with  respect  to
salaries  and  related  personnel  expenses  associated  with  our  European  and  Indian  operations.  Additionally,  for  the  year  ended  December  31,  2023,
approximately 23% of our revenues were generated in foreign currencies. Accordingly, changes in exchange rates may have a material adverse effect on
our business, operating results and financial condition. The exchange rate between the U.S. dollar and foreign currencies has fluctuated substantially in
recent  years  and  may  continue  to  fluctuate  substantially  in  the  future.  We  expect  that  a  majority  of  our  revenues  will  continue  to  be  generated  in  U.S.
dollars for the foreseeable future and that a significant portion of our expenses, including personnel costs, as well as capital and operating expenditures, will
continue  to  be  denominated  in  the  Euro,  British  Pound  and  Indian  Rupee.  The  result  of  our  operations  may  be  adversely  affected  by  foreign  exchange
fluctuations.

We  use  derivative  financial  instruments  to  reduce  our  foreign  currency  exchange  risks.  We  use  foreign  currency  forward  contracts  to  mitigate  the
impact of foreign currency fluctuations of certain non-U.S. dollar denominated net asset positions, to date primarily cash, accounts receivable and operating
lease liabilities (non-designated), as well as to manage foreign currency fluctuation risk related to forecasted transactions (designated). However, we may
not  be  able  to  purchase  derivative  instruments  that  are  adequate  to  insulate  ourselves  from  foreign  currency  exchange  risks.  Additionally,  our  hedging
activities may contribute to increased losses as a result of volatility in foreign currency markets.

If the market for cloud solutions for IT, security and compliance does not evolve as we anticipate, our revenues may not grow and our operating results
would be harmed.

Our  success  depends  to  a  significant  extent  on  the  willingness  of  organizations  to  increase  their  use  of  cloud  solutions  for  their  IT,  security  and
compliance. Some organizations may be reluctant to use cloud solutions because they have concerns regarding the risks associated with the reliability or
security of the technology delivery model associated with these solutions. If other cloud service providers experience security incidents, loss of customer
data, disruptions in service delivery or other problems, the market for cloud solutions as a whole, including our solutions, may be negatively impacted.
Moreover,  organizations  that  have  invested  substantial  personnel  and  financial  resources  to  integrate  on-premise  software  into  their  businesses  may  be
reluctant or unwilling to migrate to a cloud solution. Organizations that use on-premise security products, such as network firewalls, security information
and  event  management  products  or  data  loss  prevention  solutions,  may  also  believe  that  these  products  sufficiently  protect  their  IT  infrastructure  and
deliver  adequate  security.  Therefore,  they  may  continue  spending  their  IT  security  budgets  on  these  products  and  may  not  adopt  our  IT,  security  and
compliance solutions in addition to or as a replacement for such products.

If  customers  do  not  recognize  the  benefits  of  our  cloud  solutions  over  traditional  on-premise  enterprise  software  products,  and  as  a  result  we  are

unable to increase sales of subscriptions to our solutions, then our revenues may not grow or may decline, and our operating results would be harmed.

Our  business  and  operations  have  continued  to  grow  since  inception,  and  if  we  do  not  appropriately  manage  any  future  growth,  or  are  unable  to
improve our systems and processes, our operating results may be negatively affected.

We  have  continued  to  grow  over  the  last  several  years,  with  revenues  increasing  from  $411.2  million  in  2021  to  $554.5  million  in  2023,  and
headcount increasing from 1,498 employees at the beginning of 2021 to 2,188 employees as of December 31, 2023. We rely on information technology
systems to help manage critical functions such as order processing, revenue recognition and financial forecasts. To manage any future growth effectively
we must continue to improve and expand our IT systems, financial infrastructure, and operating and administrative systems and controls, and continue to
manage  headcount,  capital  and  processes  in  an  efficient  manner.  We  may  not  be  able  to  successfully  implement  improvements  to  these  systems  and
processes in a timely or efficient manner.

Our failure to improve our systems and processes, or their failure to operate in the intended manner, may result in our inability to manage the growth
of  our  business  and  to  accurately  forecast  our  revenues,  expenses  and  earnings,  or  to  prevent  certain  losses.  In  addition,  as  we  continue  to  grow,  our
productivity and the quality of our solutions may also be adversely affected if we do not integrate and train our new employees quickly and effectively. Any
future growth would add complexity to our organization and require effective coordination across our organization. Failure to manage any future growth
effectively could result in increased costs, harm our results of operations and lead to investors losing confidence in our internal systems and processes.

We depend on the continued services and performance of our senior management and other key employees, the loss of any of whom could adversely
affect our business, operating results and financial condition.

Our future performance depends to a significant extent on the continued services and continuing contributions of our senior management and other
key  employees,  to  execute  on  our  business  plan  and  to  identify  and  pursue  new  opportunities  and  product  innovations.  We  do  not  maintain  key-man
insurance for any member of our senior management team. Our senior management and key employees are generally employed on an at-will basis, which
means that they could terminate their employment with us at any time. From time to time, there may be changes in our senior management team resulting
from  the  termination  or  departure  of  executives.  The  loss  of  the  services  of  our  senior  management  or  other  key  employees  for  any  reason  could
significantly  delay  or  prevent  the  achievement  of  our  development  and  strategic  objectives  and  harm  our  business,  financial  condition  and  results  of
operations.

If we are unable to hire, retain and motivate qualified personnel, our business may suffer.

Our future success depends, in part, on our ability to continue to attract and retain highly skilled personnel. The loss of the services of any of our key
personnel, the inability to attract or retain qualified personnel or delays in hiring required personnel, particularly in engineering and sales, may seriously
harm  our  business,  financial  condition  and  results  of  operations.  Any  of  our  employees  may  terminate  their  employment  at  any  time.  Competition  for
highly skilled personnel is frequently intense, especially within our industry, and we may not be able to compete for such personnel.

We  are  required  under  accounting  principles  generally  accepted  in  the  United  States  (U.S.  GAAP)  to  recognize  compensation  expense  in  our
operating results for employee stock-based compensation under our equity grant programs, which may negatively impact our operating results and may
increase the pressure to limit stock-based compensation that we might otherwise offer to current or potential employees, thereby potentially harming our
ability to attract or retain highly skilled personnel. In addition, to the extent we hire personnel from competitors, we may be subject to allegations that they
have been improperly solicited or divulged proprietary or other confidential information, which could result in a diversion of management's time and our
resources.

A portion of our revenues are generated by sales to government entities, which are subject to a number of challenges and risks.

Government  entities  have  historically  been  particularly  concerned  about  adopting  cloud-based  solutions  for  their  operations,  including  security
solutions, and increasing sales of subscriptions for our solutions to government entities may be more challenging than selling to commercial organizations.
Selling to government entities can be highly competitive, expensive and time-consuming, often requiring significant upfront time and expense without any
assurance that we will win a sale. We have invested in the creation of a cloud offering certified under the Federal Information Security Management Act for
government usage but we cannot be sure that we will continue to sustain or renew this certification, that the government will continue to mandate such
certification or that other government agencies or entities will use this cloud offering. Government demand and payment for our solutions may be impacted
by public sector budgetary cycles and funding authorizations, with funding reductions or delays adversely affecting public sector demand for our solutions.
Government entities may have contractual or other legal rights to terminate contracts with our channel partners for convenience or due to a default, and any
such  termination  may  adversely  impact  our  future  results  of  operations.  Governments  routinely  investigate  and  audit  government  contractors’
administrative processes, and any unfavorable audit could result in the government refusing to continue buying our solutions, a reduction of revenues or
fines or civil or criminal liability if the audit uncovers improper or illegal activities. Any such penalties could adversely impact our results of operations in
a material way.

Our success in acquiring and integrating other businesses, products or technologies could impact our financial position.

In order to remain competitive, we have in the past and may in the future seek to acquire additional businesses, products, services or technologies. For
example,  we  acquired  certain  intellectual  property  of  TotalCloud  on  August  19,  2021  and  certain  assets  of  Blue  Hexagon  on  October  4,  2022.  The
environment  for  acquisitions  in  our  industry  is  very  competitive  and  acquisition  candidate  purchase  prices  may  exceed  what  we  would  prefer  to  pay.
Moreover,  achieving  the  anticipated  benefits  of  past  and  future  acquisitions  will  depend  in  part  upon  whether  we  can  integrate  acquired  operations,
products and technology in a timely and cost-effective manner, and even if we achieve benefits from acquisitions, such acquisitions may still be viewed
negatively by customers, financial markets or investors. The acquisition and integration process is complex, expensive and time-consuming, and may cause
an interruption of, or loss of momentum in, product development and sales activities and operations of both companies, as well as divert the attention of
management, and we may incur substantial cost and expense. We may issue equity securities which could dilute current stockholders’ ownership, incur
debt, assume contingent or other liabilities and expend cash in acquisitions, which could negatively impact our financial position, stockholder equity and
stock price. We may not find suitable acquisition candidates, and acquisitions we complete may be unsuccessful. If we consummate a transaction, we may
be unable to integrate and manage acquired products and businesses effectively or retain key personnel. If we are unable to effectively execute acquisitions,
our business, financial condition and operating results could be adversely affected.

We rely on software-as-a-service vendors to operate certain functions of our business and any failure of such vendors to provide services to us could
adversely impact our business and operations.

We rely on third-party software-as-a-service vendors to operate certain critical functions of our business, including financial management and human
resource  management.  If  these  services  become  unavailable  due  to  extended  outages  or  interruptions  or  because  they  are  no  longer  available  on
commercially  reasonable  terms  or  prices,  our  expenses  could  increase,  our  ability  to  manage  our  finances  could  be  interrupted  and  our  processes  for
managing  sales  of  our  solutions  and  supporting  our  customers  could  be  impaired  until  equivalent  services,  if  available,  are  identified,  obtained  and
integrated, all of which could harm our business.

Incorrect or improper implementation or use of our solutions could result in customer dissatisfaction and harm our business and reputation.

If  our  customers  are  unable  to  implement  our  solutions  successfully,  customer  perceptions  of  our  platform  and  solutions  may  be  impaired  or  our
reputation  and  brand  may  suffer.  Our  customers  have  in  the  past  inadvertently  misused  our  solutions,  which  triggered  downtime  in  their  internal
infrastructure  until  the  problem  was  resolved.  Additionally,  any  failure  to  implement  and  configure  our  solutions  correctly  may  result  in  our  solutions
failing to detect vulnerabilities or compliance issues, or otherwise to perform effectively, and may result in disruptions to our customers’ IT environments
and  businesses.  Any  misuse  of  our  solutions,  including  any  failure  to  implement  and  configure  them  appropriately,  could  result  in  disruption  to  our
customers’ businesses, customer dissatisfaction, negative impacts on the perceived reliability or effectiveness of our solutions, and claims and litigation,
and may result in negative press coverage, negative effects on our reputation and competitive position, a loss of sales, customers, and channel partners, and
harm our financial results.

We recognize revenues from subscriptions over the term of the relevant service period, and therefore any decreases or increases in bookings are not
immediately reflected in our operating results.

We recognize revenues from subscriptions over the term of the relevant service period, which is typically one year. As a result, most of our reported
revenues  in  each  quarter  are  derived  from  the  recognition  of  deferred  revenues  relating  to  subscriptions  entered  into  during  previous  quarters.
Consequently, a shortfall in demand for our solutions in any period may not significantly reduce our revenues for that period, but could negatively affect
revenues in future periods. Accordingly, the effect of significant downturns in bookings may not be fully reflected in our results of operations until future
periods. We may be unable to adjust our costs and expenses to compensate for such a potential shortfall in revenues. Our subscription model also makes it
difficult for us to rapidly increase our revenues through additional bookings in any period, as revenues are recognized ratably over the subscription period.

Our  business  is  subject  to  the  risks  of  earthquakes,  fire,  power  outages,  floods  and  other  catastrophic  events,  and  to  interruption  by  man-made
problems such as terrorism.

A  significant  natural  disaster,  such  as  an  earthquake,  fire  or  a  flood,  or  a  significant  power  outage  could  have  a  material  adverse  impact  on  our
business, operating results and financial condition. Our corporate headquarters and a significant portion of our operations are located in the San Francisco
Bay Area, a region known for seismic activity. In addition, natural disasters could affect our business partners’ ability to perform services for us on a timely
basis. In the event we or our business partners are hindered by any of the events discussed above, our ability to provide our solutions to customers could be
delayed, resulting in our missing financial targets, such as revenues and net income, for a particular quarter. Further, if a natural disaster occurs in a region
from  which  we  derive  a  significant  portion  of  our  revenues,  customers  in  that  region  may  delay  or  forego  subscriptions  of  our  solutions,  which  may
materially and adversely impact our results of operations for a particular period. In addition, war, acts of terrorism, pandemics or other health emergencies,
or responses to these events could cause disruptions in our business or the business of our business partners, customers or the economy as a whole. All of
the aforementioned risks may be exacerbated if the disaster recovery plans for us and our suppliers prove to be inadequate. To the extent that any of the
above results in delays of customer subscriptions or commercialization of our solutions, our business, financial condition and results of operations could be
adversely affected.

Risks Related to Intellectual Property, Legal, Tax and Regulatory Matters

Undetected software errors or flaws in our solutions could harm our reputation, decrease market acceptance of our solutions or result in liability.

Our solutions may contain undetected errors or defects when first introduced or as new versions are released. We have experienced these errors or
defects in the past in connection with new solutions and solution upgrades and we expect that these errors or defects will be found from time to time in the
future  in  new  or  enhanced  solutions  after  commercial  release  of  these  solutions.  Since  our  customers  use  our  solutions  for  IT,  security  and  compliance
reasons,  any  errors,  defects,  disruptions  in  service  or  other  performance  problems  with  our  solutions,  or  any  other  failure  of  our  solutions  to  detect
vulnerabilities or compliance problems or otherwise to perform effectively, may result in disruptions or damage to the business of our customers, including
security breaches or compliance failures. Additionally, any such issues, or the perception that they have occurred, whether or not relating to any actual or
perceived  error  or  defect  in  our  solutions,  could  hurt  our  reputation  and  competitive  position  and  we  may  incur  significant  costs,  the  attention  of  key
personnel  could  be  diverted,  our  customers  may  delay  or  withhold  payment  to  us  or  elect  not  to  renew,  we  could  face  a  loss  of  sales,  customers,  and
channel partners, and other significant problems with our relationships with customers and channel partners may arise. We may also be subject to liability
claims for damages related to actual or perceived errors or defects in our solutions. A material liability claim or other occurrence that harms our reputation
or decreases market acceptance of our solutions may harm our business, competitive and financial position, and operating results.

Although we maintain insurance coverage that may be applicable to certain liabilities in connection with these matters, we cannot be certain that our
insurance coverage will be adequate for liabilities that actually are incurred, that insurance will continue to be available to us on economically reasonable
terms, or at all, or that any insurer will not deny coverage as to any future claim. The successful assertion of one or more large claims against us that exceed
available insurance coverage or the occurrence of changes in our insurance policies, including premium increases or the imposition of large deductible or
co-insurance requirements, could have a material and adverse effect on our business, including our financial condition, operating results and reputation.

Our solutions could be used to collect and store personal information of our customers’ employees or customers, and therefore privacy and other data
handling concerns could result in additional cost and liability to us or inhibit sales of our solutions.

We collect the names and email addresses of our customers in connection with subscriptions to our solutions. Additionally, the data that our solutions
collect  to  help  secure  and  protect  the  IT  infrastructure  of  our  customers  may  include  additional  personal  or  confidential  information  of  our  customers’
employees and their customers, and we may collect, store and otherwise process personal or confidential information more generally in connection with our
business and operations. Personal privacy has become a significant issue in the United States and in many other countries where we offer our solutions. The
regulatory framework for privacy issues worldwide is currently evolving and is likely to remain uncertain for the foreseeable future. Many federal, state
and foreign government bodies and agencies have adopted or are considering adopting laws and regulations regarding the collection, use, disclosure and
retention of personal information. In the United States, these include, for example, rules and regulations promulgated under the authority of the Federal
Trade  Commission,  the  Health  Insurance  Portability  and  Accountability  Act  of  1996,  the  Gramm-Leach-Bliley  Act,  and  state  breach  notification  laws.
Internationally, virtually every jurisdiction in which we operate has established its own data security and privacy legal framework with which we or our
customers must comply.

28

Table of Contents

These  privacy,  data  protection  and  information  security  laws  and  regulations  may  result  in  ever-increasing  regulatory  and  public  scrutiny  and
escalating levels of enforcement and sanctions. Additionally, new laws and regulations relating to privacy and data protection continue to be proposed and
enacted. For example, the European Union has adopted the Global Data Protection Regulation (“GDPR”). This regulation, which took effect in May of
2018, provides for substantial obligations relating to the handling, storage and other processing of data relating to individuals and administrative fines for
violations, which can be up to four percent of the previous year’s annual revenue or €20 million, whichever is higher. The GDPR may be subject to new or
changing interpretations by courts, and our interpretation of the law and efforts to comply with the rules and regulations of the law may be ruled invalid.
Similarly,  the  California  Consumer  Privacy  Act  (“CCPA”)  requires  covered  companies  to,  among  other  things,  provide  new  disclosures  to  California
consumers and affords such consumers new rights to opt-out of certain sales of personal information. The CCPA also creates a private right of action for
statutory damages for certain breaches of information. Additionally, the California Privacy Rights Act (“CPRA”), was approved by voters in the November
3,  2020  election.  The  CPRA  modified  the  CCPA  significantly,  creating  obligations  relating  to  consumer  data  beginning  on  January  1,  2022,  with
enforcement  authorized  as  of  July  1,  2023.  In  addition,  other  states  have  enacted  or  proposed  legislation  that  regulates  the  collection,  use,  and  sale  of
personal information, including, for example, Washington's My Health, My Data Act and legislation similar to the CCPA adopted in Virginia, Colorado,
Utah,  Connecticut,  Iowa,  Indiana,  Montana,  Tennessee,  Oregon,  Florida,  Delaware,  and  Texas.  Aspects  of  the  CCPA,  CPRA,  and  these  other  new  and
evolving state laws, as well their interpretation and enforcement, remain uncertain. We cannot predict the impact of the CCPA, CPRA, or other evolving
privacy and data protection obligations on our business or operations, but they may require us to modify our data processing practices and policies and
incur substantial costs and expenses in an effort to comply.

The privacy, data protection, and information security laws and regulations we must comply with also are subject to change. For example, the United
Kingdom has enacted a Data Protection Act, and has implemented legislation referred to as the “UK GDPR,” that substantially implement the GDPR in the
United Kingdom following the United Kingdom’s exit from the European Union. This legislation provides for substantial penalties for noncompliance of
up to the greater of £17.5 million or four percent of the previous year’s annual revenues. While the European Union has deemed the United Kingdom an
“adequate country” to which personal data could be exported from the European Economic Area (“EEA”), this decision is required to be renewed after four
years of being in effect and may be modified, revoked, or challenged in the interim, creating uncertainty regarding transfers of personal data to the United
Kingdom from the EEA. It remains unclear how United Kingdom data protection laws or regulations will develop in the medium to longer term and how
data transfers to and from the United Kingdom will be regulated. Additionally, we have self-certified under the EU-U.S. Data Privacy Framework and a
related program, the Swiss-U.S. Data Privacy Framework, and have adopted certain standard contractual clauses approved by the European Commission
(“SCCs”)  as  part  of  our  data  processing  agreements  with  regard  to  certain  transfers  of  personal  data  from  the  EEA  to  the  U.S.  Both  the  EU-U.S.  Data
Privacy Framework and SCCs have, however, been subject to legal challenge. In its July 16, 2020 opinion, the CJEU imposed additional obligations on
companies when relying on SCCs to transfer personal data. The European Commission has published revised SCCs addressing the CJEU concerns on June
4, 2021, that are required to be implemented. The United Kingdom has adopted new standard contractual clauses (“UK SCCs”), that became effective as of
March  21,  2022,  and  which  also  are  required  to  be  implemented.  The  EU-U.S.  Data  Privacy  Framework,  Swiss-U.S.  Data  Privacy  Framework  revised
SCCs  and  UK  SCCs,  guidance  and  opinions  of  regulators,  and  other  developments  relating  to  cross-border  data  transfer  may  require  us  to  implement
additional contractual and technical safeguards for any personal data transferred out of Europe, which may increase compliance costs, lead to increased
regulatory  scrutiny  or  liability,  and  which  may  adversely  impact  our  business,  financial  condition  and  operating  results.  We  may  be  unsuccessful  in
maintaining  legitimate  means  for  our  transfer  and  receipt  of  personal  data  from  the  EEA  or  Switzerland.  We  may  experience  reluctance  or  refusal  by
current  or  prospective  European  customers  to  use  our  products,  and  we  and  our  customers  may  face  a  risk  of  enforcement  actions  by  data  protection
authorities in the EEA relating to personal data transfers to us and by us from the EEA. Any such enforcement actions could result in substantial costs and
diversion  of  resources,  distract  management  and  technical  personnel  and  negatively  affect  our  business,  operating  results  and  financial  condition.  Some
countries also are considering or have passed legislation requiring local storage and processing of data, or similar requirements, which could increase the
cost and complexity of delivering our services.

29

Table of Contents

In addition to laws and regulations, privacy advocacy and industry groups or other private parties may propose new and different privacy standards
that either legally or contractually apply to us. Because the interpretation and application of privacy and data protection laws, regulations, standards and
contractual obligations are uncertain, it is possible that they may be interpreted and applied in a manner that is, or perceived to be, inconsistent with our
data management practices or the features of our solutions. If so, in addition to the possibility of regulatory investigations and enforcement actions, fines,
lawsuits and other claims, other forms of injunctive or operations-limiting relief, and damage to our reputations and loss of goodwill, we could be required
to fundamentally change our business activities and practices or modify our solutions and may face limitations in our ability to develop new solutions and
features, any of which could have an adverse effect on our business. Any inability to adequately address privacy concerns, even if unfounded, or any actual
or perceived inability to comply with applicable privacy or data protection laws, regulations and privacy standards, could result in cost and liability to us,
damage our reputation, inhibit sales of subscriptions and harm our business.

Furthermore,  the  costs  of  compliance  with,  and  other  burdens  imposed  by,  the  laws,  regulations,  and  privacy  standards  that  are  applicable  to  the
businesses of our customers may limit the use and adoption of, and reduce the overall demand for, our solutions. Privacy concerns, whether valid or not
valid, may inhibit market adoption of our solutions particularly in certain industries and foreign countries.

We use AI/machine learning technologies in our solutions that could result in harm to our business and operating results.

We have incorporated and may continue to incorporate additional AI/machine learning solutions and features into our solutions, and these solutions
and  features  may  become  more  important  to  our  operations  or  to  our  future  growth  over  time.  We  expect  to  rely  on  AI/machine  learning  solutions  and
features to help drive future growth in our business, but there can be no assurance that we will realize the desired or anticipated benefits from AI/machine
learning or at all. We may also fail to properly implement or market our AI/machine learning solutions and features. Our competitors or other third parties
may incorporate AI/machine learning into their products, offerings, and solutions more quickly or more successfully than us, which could impair our ability
to compete effectively and adversely affect our results of operations. Additionally, our offerings based on AI/machine learning may expose us to additional
claims, demands and proceedings by private parties and regulatory authorities and subject us to legal liability as well as brand and reputational harm. The
legal, regulatory, and policy environments around AI/machine learning are evolving rapidly, and we may become subject to new and evolving legal and
other obligations. These and other developments may require us to make significant changes to our use of AI/machine learning, including by limiting or
restricting  our  use  of  AI/machine  learning,  and  which  may  require  us  to  make  significant  changes  to  our  policies  and  practices,  which  may  necessitate
expenditure of significant time, expense, and other resources, AI/machine learning also presents emerging ethical issues that could harm our reputation and
business if our use of AI/machine learning becomes controversial.

Our solutions contain third-party open source software components, and our failure to comply with the terms of the underlying open source software
licenses could restrict our ability to sell our solutions.

Our solutions contain software licensed to us by third-parties under so-called “open source” licenses, including the GNU General Public License, the
GNU Lesser General Public License, the BSD License, the Apache License and others. From time to time, there have been claims against companies that
distribute or use open source software in their products and services, asserting that such open source software infringes the claimants’ intellectual property
rights. We could be subject to suits by parties claiming that what we believe to be licensed open source software infringes their intellectual property rights.
Use and distribution of open source software may entail greater risks than use of third-party commercial software, as open source licensors generally do not
provide  warranties  or  other  contractual  protections  regarding  infringement  claims  or  the  quality  of  the  code.  In  addition,  certain  open  source  licenses
require that source code for software programs that are subject to the license be made available to the public and that any modifications or derivative works
to such open source software continue to be licensed under the same terms. If we combine our proprietary software with open source software in certain
ways, we could, in some circumstances, be required to release the source code of our proprietary software to the public. Disclosing the source code of our
proprietary  software  could  make  it  easier  for  cyber  attackers  and  other  third  parties  to  discover  vulnerabilities  in  or  to  defeat  the  protections  of  our
solutions, which could result in our solutions failing to provide our customers with the security they expect from our services. This could harm our business
and reputation. Disclosing our proprietary source code also could allow our competitors to create similar products with lower development effort and time
and ultimately could result in a loss of sales for us. Any of these events could have a material adverse effect on our business, operating results and financial
condition.

Although we monitor our use of open source software in an effort both to comply with the terms of the applicable open source licenses and to avoid
subjecting our solutions to conditions we do not intend, the terms of many open source licenses have not been interpreted by U.S. courts, and there is a risk
that these licenses could be construed in a way that could impose unanticipated conditions or restrictions on our ability to commercialize our solutions. In
this event, we could be required to seek

30

Table of Contents

licenses  from  third  parties  to  continue  offering  our  solutions,  to  make  our  proprietary  code  generally  available  in  source  code  form,  to  re-engineer  our
solutions or to discontinue the sale of our solutions if re-engineering could not be accomplished on a timely basis, any of which could adversely affect our
business, operating results and financial condition.

We use third-party software and data that may be difficult to replace or cause errors or failures of our solutions that could lead to lost customers or
harm to our reputation and our operating results.

We license third-party software as well as security and compliance data from various third parties to deliver our solutions. In the future, this software
or data may not be available to us on commercially reasonable terms, or at all. Any loss of the right to use any of this software or data could result in delays
in the provisioning of our solutions until equivalent technology or data is either developed by us, or, if available, is identified, obtained and integrated,
which could harm our business. In addition, any errors or defects in or failures of this third-party software or data could result in errors or defects in our
solutions or cause our solutions to fail, which could harm our business and be costly to correct. Many of these providers attempt to impose limitations on
their liability for such errors, defects or failures, and if enforceable, we may have additional liability to our customers or third-party providers that could
harm our reputation and increase our operating costs.

We will need to maintain our relationships with third-party software and data providers, and to obtain software and data from such providers that do
not contain any errors or defects. Any failure to do so could adversely impact our ability to deliver effective solutions to our customers and could harm our
operating results.

Failure to protect our proprietary technology and intellectual property rights could substantially harm our business and operating results.

The  success  of  our  business  depends  in  part  on  our  ability  to  protect  and  enforce  our  trade  secrets,  trademarks,  copyrights,  patents  and  other
intellectual  property  rights.  We  attempt  to  protect  our  intellectual  property  under  copyright,  trade  secret,  patent  and  trademark  laws,  and  through  a
combination of confidentiality procedures, contractual provisions and other methods, all of which offer only limited protection.

We  primarily  rely  on  our  unpatented  proprietary  technology  and  trade  secrets.  Despite  our  efforts  to  protect  our  proprietary  technology  and  trade
secrets, unauthorized parties may attempt to misappropriate, reverse engineer or otherwise obtain and use them. The contractual provisions that we enter
into  with  employees,  consultants,  partners,  vendors  and  customers  may  not  prevent  unauthorized  use  or  disclosure  of  our  proprietary  technology  or
intellectual  property  rights  and  may  not  provide  an  adequate  remedy  in  the  event  of  unauthorized  use  or  disclosure  of  our  proprietary  technology  or
intellectual property rights. Moreover, policing unauthorized use of our technologies, solutions and intellectual property is difficult, expensive and time-
consuming, particularly in foreign countries where the laws may not be as protective of intellectual property rights as those in the United States and where
mechanisms  for  enforcement  of  intellectual  property  rights  may  be  weak.  We  may  be  unable  to  determine  the  extent  of  any  unauthorized  use  or
infringement of our solutions, technologies or intellectual property rights.

The process of obtaining patent protection is expensive and time-consuming, and we may not be able to prosecute all necessary or desirable patent
applications at a reasonable cost or in a timely manner, if at all. We may choose not to seek patent protection for certain innovations and may choose not to
pursue patent protection in certain jurisdictions.

Furthermore, it is possible that our patent applications may not result in granted patents, that the scope of our issued patents will be limited or not
provide  the  coverage  originally  sought,  that  our  issued  patents  will  not  provide  us  with  any  competitive  advantages,  or  that  our  patents  and  other
intellectual property rights may be challenged by others or invalidated through administrative processes or litigation. In addition, issuance of a patent does
not guarantee that we have an absolute right to practice the patented invention. As a result, we may not be able to obtain adequate patent protection or to
enforce our issued patents effectively.

From time to time, legal action by us may be necessary to enforce our patents and other intellectual property rights, to protect our trade secrets, to
determine the validity and scope of the intellectual property rights of others or to defend against claims of infringement or invalidity. Such litigation could
result in substantial costs and diversion of resources and could negatively affect our business, operating results and financial condition. If we are unable to
protect our intellectual property rights, we may find ourselves at a competitive disadvantage to others who need not incur the additional expense, time and
effort required to create the innovative solutions that have enabled us to be successful to date.

Assertions by third parties of infringement or other violations by us of their intellectual property rights could result in significant costs and harm our
business and operating results.

Patent and other intellectual property disputes are common in our industry. Some companies, including some of our competitors, own large numbers
of  patents,  copyrights  and  trademarks,  which  they  may  use  to  assert  claims  against  us.  Third  parties  may  in  the  future  assert  claims  of  infringement,
misappropriation or other violations of intellectual property rights against us. They may also assert such claims against our customers or channel partners
whom we typically indemnify against claims that our solutions infringe, misappropriate or otherwise violate the intellectual property rights of third parties.
As the numbers of products and competitors in our market increase and overlaps occur, claims of infringement, misappropriation and other violations of
intellectual  property  rights  may  increase.  Any  claim  of  infringement,  misappropriation  or  other  violation  of  intellectual  property  rights  by  a  third  party,
even those without merit, could cause us to incur substantial costs defending against the claim and could distract our management from our business.

The patent portfolios of our most significant competitors are larger than ours. This disparity may increase the risk that they may sue us for patent
infringement and may limit our ability to counterclaim for patent infringement or settle through patent cross-licenses. In addition, future assertions of patent
rights by third parties, and any resulting litigation, may involve patent holding companies or other adverse patent owners who have no relevant product
revenues and against whom our own patents may therefore provide little or no deterrence or protection. There can be no assurance that we will not be found
to infringe or otherwise violate any third-party intellectual property rights or to have done so in the past.

An adverse outcome of a dispute may require us to:

•

•

•

•

•

pay substantial damages, including treble damages, if we are found to have willfully infringed a third party’s patents or copyrights;

cease making, licensing or using solutions that are alleged to infringe or misappropriate the intellectual property of others;

expend additional development resources to attempt to redesign our solutions or otherwise develop non-infringing technology, which may
not be successful;

enter  into  potentially  unfavorable  royalty  or  license  agreements  in  order  to  obtain  the  right  to  use  necessary  technologies  or  intellectual
property rights; and

indemnify our partners and other third parties.

In  addition,  royalty  or  licensing  agreements,  if  required  or  desirable,  may  be  unavailable  on  terms  acceptable  to  us,  or  at  all,  and  may  require
significant royalty payments and other expenditures. Some licenses may also be non-exclusive, and therefore our competitors may have access to the same
technology licensed to us. Any of the foregoing events could seriously harm our business, financial condition and results of operations.

Governmental export or import controls could subject us to liability if we violate them or limit our ability to compete in foreign markets.

Our solutions are subject to U.S. export controls, specifically, the Export Administration Regulations and economic sanctions enforced by the Office
of Foreign Assets Control. We incorporate encryption technology into certain of our solutions. These encryption solutions and the underlying technology
may be exported only with the required export authorizations, including by license, a license exception or other appropriate government authorizations.
U.S.  export  controls  may  require  submission  of  an  encryption  registration,  product  classification  and/or  annual  or  semi-annual  reports.  Governmental
regulation  of  encryption  technology  and  regulation  of  imports  or  exports  of  encryption  products,  or  our  failure  to  obtain  required  import  or  export
authorization  for  our  solutions,  when  applicable,  could  harm  our  international  sales  and  adversely  affect  our  revenues.  Compliance  with  applicable
regulatory requirements regarding the export of our solutions, including with respect to new releases of our solutions, may create delays in the introduction
of  our  solutions  in  international  markets,  prevent  our  customers  with  international  operations  from  deploying  our  solutions  throughout  their  globally-
distributed systems or, in some cases, prevent the export of our solutions to some countries altogether. In addition, various countries regulate the import of
our appliance-based solutions and have enacted laws that could limit our ability to distribute solutions or could limit our customers’ ability to implement
our  solutions  in  those  countries.  Any  new  export  or  import  restrictions,  new  legislation  or  shifting  approaches  in  the  enforcement  or  scope  of  existing
regulations, or in the countries, persons or technologies targeted by such regulations, could result in decreased use of our solutions by existing customers
with  international  operations,  declining  adoption  of  our  solutions  by  new  customers  with  international  operations  and  decreased  revenues.  If  we  fail  to
comply with export and import regulations, we may be fined or other penalties could be imposed, including denial of certain export privileges.

If we are required to collect higher sales and use or other taxes on the solutions we sell, we may be subject to liability for past sales and our future sales
may decrease.

Taxing jurisdictions, including state and local entities, have differing rules and regulations governing sales and use or other taxes, and these rules and
regulations are subject to varying interpretations that may change over time. In particular, the applicability of sales taxes to our subscription services in
various  jurisdictions  is  unclear.  It  is  possible  that  we  could  face  sales  tax  audits  and  that  our  liability  for  these  taxes  could  exceed  our  estimates  as  tax
authorities could still assert that we are obligated to collect additional amounts as taxes from our customers and remit those taxes to those authorities. We
could also be subject to audits with respect to state and international jurisdictions for which we may not have accrued tax liabilities. A successful assertion
that we should be collecting additional sales or other taxes on our services in jurisdictions where we have not historically done so and do not accrue for
sales taxes could result in substantial tax liabilities for past sales, discourage customers from purchasing our solutions or otherwise harm our business and
operating results.

Changes in our income tax provision or adverse outcomes resulting from examination of our income tax returns could adversely affect our operating
results. We could be subject to additional taxes.

We are subject to income taxes in the United States and various foreign jurisdictions, and our domestic and international tax liabilities are subject to
the  allocation  of  expenses  in  differing  jurisdictions.  Our  tax  rate  is  affected  by  changes  in  the  mix  of  earnings  and  losses  in  countries  with  differing
statutory  tax  rates,  certain  non-deductible  expenses,  excess  tax  benefits  arising  from  stock-based  compensation,  other  tax  benefits  and  credits,  and  the
valuation of deferred tax assets and liabilities. Increases in our effective tax rate could harm our operating results.

Additionally,  significant  judgment  is  required  in  evaluating  our  tax  positions  and  our  worldwide  tax  provisions.  During  the  ordinary  course  of
business, there are many activities and transactions for which the ultimate tax determination is uncertain. In addition, our tax obligations and effective tax
rates  could  be  adversely  affected  by  changes  in  the  relevant  tax,  accounting  and  other  laws,  regulations,  principles  and  interpretations,  including  those
relating to income tax nexus, by recognizing tax losses or lower than anticipated earnings in jurisdictions where we have lower statutory rates and higher
than  anticipated  earnings  in  jurisdictions  where  we  have  higher  statutory  rates,  by  changes  in  foreign  currency  exchange  rates,  or  by  changes  in  the
valuation of our deferred tax assets and liabilities. The Tax Cuts and Jobs Act of 2017 introduced a Base Erosion and Anti-Abuse Tax which imposes a
minimum  tax  on  adjusted  income  of  corporations  with  average  applicable  gross  receipt  of  at  least  $500  million  for  prior  three  tax  years  and  that  make
certain payments to related foreign persons. While these rules do not impact our results of operations in the current year, these could impact our financial
results in future periods. The Organization for Economic Cooperation and Development has issued model rules in connection with the Base Erosion and
Profit Shifting integrated framework that determine multi-jurisdictional taxing rights (Pillar One) and the minimum rate of tax applicable to certain types of
income (Pillar Two). Many countries have enacted legislation to apply the Pillar Two directive for tax years beginning in January 2024, which generally
provides for a minimum effective tax rate of 15% on the income arising in each jurisdiction where the Company operates. We do not anticipate these rules
to have an impact on our current year’s financial results. If applicable in the future, these could have an impact on our financial results, the extent of which
is currently uncertain. We may be audited in various jurisdictions, and such jurisdictions may assess additional taxes, sales taxes and value-added taxes
against us. Although we believe our tax estimates are reasonable, the final determination of any tax audits or litigation could be materially different from
our historical tax provisions and accruals, which could have a material adverse effect on our operating results or cash flows in the period or periods for
which a determination is made.

Risks Related to Ownership of Our Common Stock

Market volatility may affect our stock price and the value of an investment in our common stock and could subject us to litigation.

The trading price of our common stock has been, and may continue to be, subject to significant fluctuations in response to a number of factors, most

of which we cannot predict or control, including:

•

•

•

•

•

announcements of new solutions, services or technologies, commercial relationships, acquisitions or other events by us or our competitors;

fluctuations in stock market prices and trading volumes of securities of similar companies;

general market conditions and overall fluctuations in U.S. equity markets;

variations in our operating results, or the operating results of our competitors;

changes in our financial guidance or securities analysts’ estimates of our financial performance;

33

Table of Contents

•

•

•

•

•

•

changes in accounting principles;

sales of large blocks of our common stock, including sales by our executive officers, directors and significant stockholders;

additions or departures of any of our key personnel;

announcements related to litigation;

changing legal or regulatory developments in the United States and other countries; and

discussion of us or our stock price by the financial press and in online investor communities.

In addition, the stock market in general, and the stocks of technology companies such as ours in particular, have experienced substantial price and
volume volatility that is often seemingly unrelated to the operating performance of particular companies. These broad market fluctuations may cause the
trading  price  of  our  common  stock  to  decline.  In  the  past,  securities  class  action  litigation  has  often  been  brought  against  a  company  after  a  period  of
volatility in the trading price of its common stock. We may become involved in this type of litigation in the future. Any securities litigation claims brought
against us could result in substantial expenses and the diversion of our management’s attention from our business.

Our actual operating results may differ significantly from our guidance.

From time to time, we have released, and may continue to release, guidance in our quarterly earnings conference calls, quarterly earnings releases, or
otherwise, regarding our future performance that represents our management's estimates as of the date of release. This guidance, which includes forward-
looking  statements,  has  been  and  will  be  based  on  projections  prepared  by  our  management.  These  projections  are  not  prepared  with  a  view  toward
compliance with published guidelines of the American Institute of Certified Public Accountants, and neither our registered public accountants nor any other
independent  expert  or  outside  party  compiles  or  examines  the  projections.  Accordingly,  no  such  person  expresses  any  opinion  or  any  other  form  of
assurance with respect to the projections.

Projections  are  based  upon  a  number  of  assumptions  and  estimates  that,  while  presented  with  numerical  specificity,  are  inherently  subject  to
significant  business,  economic  and  competitive  uncertainties  and  contingencies,  many  of  which  are  beyond  our  control  and  are  based  upon  specific
assumptions with respect to future business decisions, some of which will change. We intend to state possible outcomes as high and low ranges which are
intended to provide a sensitivity analysis as variables are changed but are not intended to imply that actual results could not fall outside of the suggested
ranges. The principal reason that we release guidance is to provide a basis for our management to discuss our business outlook with analysts and investors.
We do not accept any responsibility for any projections or reports published by any such third parties.

Guidance is necessarily speculative in nature, and it can be expected that some or all of the assumptions underlying the guidance furnished by us will
not materialize or will vary significantly from actual results. Accordingly, our guidance is only an estimate of what management believes is realizable as of
the date of release. Actual results may vary from our guidance and the variations may be material. In light of the foregoing, investors are urged not to rely
upon our guidance in making an investment decision regarding our common stock.

Any failure to successfully implement our operating strategy or the occurrence of any of the events or circumstances set forth in this “Risk Factors”
section  in  this  Annual  Report  on  Form  10-K  could  result  in  our  actual  operating  results  being  different  from  our  guidance,  and  the  differences  may  be
adverse and material.

Future sales of shares by existing stockholders could cause our stock price to decline.

The market price of shares of our common stock could decline as a result of substantial sales of our common stock, particularly sales by our directors,
executive officers, employees and significant stockholders, a large number of shares of our common stock becoming available for sale, or the perception in
the market that holders of a large number of shares intend to sell their shares. As of December 31, 2023, we had approximately 36.9 million shares of our
common stock outstanding.

In addition, as of December 31, 2023, there were approximately 1.4 million options and 1.1 million restricted stock units outstanding. If such options
are exercised and restricted stock units are released, these additional shares will become available for sale. As of December 31, 2023, we had an aggregate
of 1.8 million shares of our common stock reserved for future issuance under our Restated 2012 Equity Incentive Plan and 0.5 million shares reserved for
future purchase under our 2021 Employee Stock Purchase Plan, which can be freely sold in the public market upon issuance. If a large number of these
shares are sold in the public market, the sales could reduce the trading price of our common stock.

We  cannot  guarantee  that  our  share  repurchase  program  will  be  fully  consummated  or  that  it  will  enhance  stockholder  value,  and  any  share
repurchases we make could affect the price of our common stock.

On February 12, 2018, we announced that our board of directors had authorized a $100.0 million repurchase program. On each of October 30, 2018,
October 30, 2019, May 7, 2020, February 10, 2021 and February 9, 2023, we announced that our board of directors had authorized an increase of $100.0
million, and on each of November 3, 2021 and May 4, 2022, we announced that our board of directors had authorized an increase of $200.0 million to the
share  repurchase  program.  On  February  7,  2024  we  announced  that  our  board  of  directors  had  authorized  an  increase  of  $200.0  million  to  the  share
repurchase program, resulting in an aggregate authorization of $1.2 billion to date ($1.0 billion as of December 31, 2023). Although our board of directors
authorized the share repurchase program, we are not obligated to repurchase any specific dollar amount or to acquire any specific number of shares. The
share repurchase program could affect the price of our common stock, increase volatility and diminish our cash reserves. In addition, it may be suspended
or terminated at any time, which may result in a decrease in the price of our common stock. Finally, our share repurchases in 2023 were subject to a new
1% excise tax introduced in the Inflation Reduction Act. The amount of share repurchases subject to the excise tax are reduced by the fair market value of
any shares issued during the taxable year. This provision does not currently, nor do we expect it to in the future, have a material impact to our results of
operations. During the year ended December 31, 2023, we repurchased 1.3 million shares of our common stock for approximately $170.8 million. As of
December 31, 2023, approximately $83.7 million remained available for share repurchases pursuant to our share repurchase program.

We do not intend to pay dividends on our common stock and therefore any returns will be limited to the value of our stock.

We  have  never  declared  or  paid  any  cash  dividend  on  our  common  stock.  We  currently  anticipate  that  we  will  retain  future  earnings  for  the
development, operation and expansion of our business and do not anticipate declaring or paying any cash dividends for the foreseeable future. Any return
to stockholders will therefore be limited to the value of their stock.

Anti-takeover  provisions  in  our  charter  documents  and  under  Delaware  law  could  make  an  acquisition  of  us,  which  may  be  beneficial  to  our
stockholders, more difficult and may prevent attempts by our stockholders to replace or remove our current management.

Our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that may delay or prevent an acquisition of

us or a change in our management. These provisions include:

•

•

•

•

•

•

authorizing “blank check” preferred stock, which could be issued by our board of directors without stockholder approval and may contain
voting, liquidation, dividend and other rights superior to our common stock, which would increase the number of outstanding shares and
could thwart a takeover attempt;

a classified board of directors whose members can only be dismissed for cause;

the prohibition on actions by written consent of our stockholders;

the limitation on who may call a special meeting of stockholders;

the establishment of advance notice requirements for nominations for election to our board of directors or for proposing matters that can be
acted upon at stockholder meetings; and

the requirement of at least two-thirds of the outstanding capital stock to amend any of the foregoing second through fifth provisions.

In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law,
which limits the ability of stockholders owning in excess of 15% of our outstanding voting stock to merge or combine with us. Although we believe these
provisions collectively provide for an opportunity to obtain greater value for stockholders by requiring potential acquirers to negotiate with our board of
directors,  they  would  apply  even  if  an  offer  rejected  by  our  board  of  directors  were  considered  beneficial  by  some  stockholders.  In  addition,  these
provisions  may  frustrate  or  prevent  any  attempts  by  our  stockholders  to  replace  or  remove  our  current  management  by  making  it  more  difficult  for
stockholders to replace members of our board of directors, which is responsible for appointing the members of our management.

General Risk Factors

Disruptive technologies could gain wide adoption and supplant our cloud-based IT, security and compliance solutions, thereby weakening our sales
and harming our results of operations.

The introduction of products and services embodying new technologies could render our existing solutions obsolete or less attractive to customers.
Our business could be harmed if new IT, security and compliance technologies are widely adopted. We may not be able to successfully anticipate or adapt
to changing technology or customer requirements on a timely basis, or at all. If we fail to keep up with technological changes or to convince our customers
and potential customers of the value of our solutions even in light of new technologies, our business could be harmed and our revenues may decline.

We may not maintain profitability in the future.

We may not be able to sustain or increase our growth or maintain profitability in the future. We plan to continue to invest in our infrastructure, new
solutions, research and development and sales and marketing, and as a result, we cannot assure you that we will maintain profitability. We may incur losses
in  the  future  for  a  number  of  reasons,  including  without  limitation,  the  other  risks  and  uncertainties  described  in  this  Annual  Report  on  Form  10-K.
Additionally, we may encounter unforeseen operating expenses, difficulties, complications, delays and other unknown factors that may result in losses in
future periods. If our revenue growth does not meet our expectations in future periods, our financial performance may be harmed and we may not again
achieve or maintain profitability in the future.

Forecasts of market growth may prove to be inaccurate, and even if the markets in which we compete achieve the forecasted growth, there can be no
assurance that our business will grow at similar rates, or at all.

Growth forecasts relating to the expected growth in the market for IT, security and compliance and other markets are subject to significant uncertainty
and are based on assumptions and estimates which may prove to be inaccurate. Even if these markets experience the forecasted growth, we may not grow
our business at similar rates, or at all. Our growth is subject to many factors, including our success in implementing our business strategy, which is subject
to many risks and uncertainties. Accordingly, forecasts of market growth should not be taken as indicative of our future growth.

Our financial results are based in part on our estimates or judgments relating to our critical accounting policies. These estimates or judgments may
prove to be incorrect, which could harm our operating results and result in a decline in our stock price.

The  preparation  of  financial  statements  in  conformity  with  U.S.  GAAP  requires  management  to  make  estimates  and  assumptions  that  affect  the
amounts reported in the consolidated financial statements and accompanying notes. We base our estimates on historical experience and on various other
assumptions that we believe to be reasonable under the circumstances, as provided in the section titled “Part II, Item 7 - Management’s Discussion and
Analysis of Financial Condition and Results of Operations,” the results of which form the basis for making judgments about the carrying values of assets,
liabilities,  equity,  revenues  and  expenses  that  are  not  readily  apparent  from  other  sources.  Our  operating  results  may  be  adversely  affected  if  our
assumptions change or if actual circumstances differ from those in our assumptions, which could cause our operating results to fall below the expectations
of  securities  analysts  and  investors,  resulting  in  a  decline  in  our  stock  price.  Significant  assumptions  and  estimates  used  in  preparing  our  consolidated
financial statements include those related to revenue recognition, accounting for income taxes and stock-based compensation.

Changes in financial accounting standards may cause adverse and unexpected revenue fluctuations and impact our reported results of operations.

We  prepare  our  financial  statements  in  accordance  with  U.S.  GAAP.  These  principles  are  subject  to  interpretation  by  the  SEC  and  various  bodies
formed to interpret and create appropriate accounting principles. A change in these accounting standards or practices could harm our operating results and
could have a significant effect on our reporting of transactions and reported results and may even retroactively affect previously reported transactions. New
accounting  pronouncements  and  varying  interpretations  of  accounting  pronouncements  have  occurred  and  may  occur  in  the  future.  Changes  to  existing
rules  or  the  questioning  of  current  practices  may  harm  our  operating  results  or  require  that  we  make  significant  changes  to  our  systems,  processes  and
controls or the way we conduct our business.

Table of Contents

If we fail to maintain an effective system of internal control over financial reporting, our ability to produce timely and accurate financial statements or
comply with applicable regulations could be impaired.

As a public company, we are subject to the reporting requirements of the Securities Exchange Act of 1934, or the Exchange Act, the Sarbanes-Oxley
Act of 2002, or the Sarbanes-Oxley Act, and the rules and regulations of the NASDAQ Stock Market. To continue to comply with the requirements of
being a public company, we may need to undertake various actions, such as implementing additional internal controls and procedures and hiring additional
accounting or internal audit staff.

Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and
the preparation of financial statements in accordance with U.S. GAAP. Our current controls and any new controls that we develop may become inadequate
because of changes in conditions in our business. Any failure to maintain effective controls, or any difficulties encountered in their improvement, could
harm our operating results or cause us to fail to meet our reporting obligations. Any failure to maintain effective internal control over financial reporting
also could adversely affect the results of periodic management evaluations regarding the effectiveness of our internal control over financial reporting that
we are required to include in our periodic reports we file with the SEC under Section 404 of the Sarbanes-Oxley Act. While we were able to assert in our
Annual Report on Form 10-K that our internal control over financial reporting was effective as of December 31, 2023, we cannot predict the outcome of
our testing in future periods. If we are unable to assert in any future reporting period that our internal control over financial reporting is effective (or if our
independent registered public accounting firm is unable to express an opinion on the effectiveness of our internal controls), investors may lose confidence
in  our  operating  results  and  our  stock  price  could  decline.  In  addition,  if  we  are  unable  to  continue  to  meet  these  requirements,  we  may  not  be  able  to
remain listed on the NASDAQ Stock Market.

Risk Management and Strategy

We  have  established  an  Information  Security  Management  System  (“ISMS”)  comprised  of  policies,  procedures,  and  processes  for  assessing,
identifying,  and  managing  material  risks  from  cybersecurity  threats,  and  have  integrated  these  processes  into  our  overall  enterprise  risk  management
systems and processes. Our ISMS is aligned to generally accepted security standards and is certified by third-party auditors according to ISO/IEC 27001
standards. We routinely assess cybersecurity risks for materiality, including assessing any potential unauthorized occurrence on or conducted through our
information  systems  that  may  result  in  adverse  effects  on  the  confidentiality,  integrity,  or  availability  of  our  information  systems  or  any  information
residing therein.

We routinely conduct risk assessments to identify cybersecurity threats and weaknesses, as well as risk assessments of events that could potentially
materially change our business practices and affect our information systems that could be impacted by cybersecurity threats and vulnerabilities. These risk
assessments include identification of reasonably foreseeable internal and external risks, the likelihood and potential damage that could result from such
risks, and the sufficiency of existing policies, procedures, systems, and safeguards in place to manage such risks.

Following these risk assessments, we re-design, implement, and maintain reasonable safeguards to minimize identified risks; reasonably address any
identified gaps in existing safeguards; and regularly monitor the effectiveness of our safeguards. We devote significant resources and designate high-level
personnel,  including  our  Chief  Information  Security  Officer  (“CISO”)  who  reports  to  our  Chief  Executive  Officer,  to  manage  the  risk  assessment  and
mitigation process.

As part of our overall risk management system, we monitor and test our safeguards and train our employees on these safeguards, in collaboration with

human resources, IT, and management. Personnel at all levels and departments are made aware of our cybersecurity policies through periodic trainings.

We have established a Computer Security Incident Response Team (“CSIRT”) that identifies security incidents, characterizes the nature and severity of
incidents,  and  provides  diagnostic  and  corrective  actions  when  appropriate.  The  security  measures  the  CSIRT  employs  are  consistent  with  relevant
requirements  of  the  National  Institute  of  Standards  and  Technology  (“NIST”),  Federal  Risk  and  Authorization  Management  Program  (“FedRAMP”),
International  Organization  for  Standardization  (“ISO”),  and  Federal  Information  Security  Management  Act  (“FISMA”).  We  have  also  adopted  certain
guidelines from NIST and the United States Computer Emergency Readiness Team.

Our Incident Response Program and Plan describes the major phases of an incident management lifecycle which includes the preparation, detection
and analysis, containment, eradication and recovery, and post-incident activity. Qualys' 24x7 Security Operations Center (“QSOC”) and CSIRT conduct
Incident Response Plan testing and training on a periodic basis through tabletop exercises or simulated attack scenarios. This testing appraises our readiness
to respond to such scenarios and tests the completeness and accuracy of the incident response plan. The QSOC and CSIRT teams drive these exercises to
participants via various cyber security incident scenarios in the form of multiple injects. Exercise participants primarily consist of members from various
Qualys departments such as security operations, IT operations, network operations, and other departments depending on the selected scenario.

We routinely evaluate the risks posed by third-party providers and engage with those whom fail to comply with our relevant contract requirements, or

when we feel further action is needed to keep our risk levels within approved tolerance levels.

We engage assessors, consultants, auditors, and other third parties in order to obtain external validation for effectiveness and adequacy of our security
posture in compliance with regulatory requirements. These service providers attest to our organization-wide design and implementation of cybersecurity
policies and procedures, and annually monitor such policies and procedures from a safety perspective.

For additional information regarding whether any risks from cybersecurity threats have materially affected or are reasonably likely to materially affect
our company, including our business strategy, results of operations, or financial condition, please refer to Item 1A, “Risk Factors,” in this annual report on
Form  10-K,  including  the  risk  factor  entitled  “Our  platform,  website  and  internal  systems  may  be  subject  to  intentional  disruption  or  other  security
incidents that could result in liability and adversely impact our reputation and future sales.” We have not currently encountered any cybersecurity threats
that have materially impaired our operations or financial standing.

Governance

Our board of directors, with assistance from management, monitors and assesses strategic risk exposure, and our management team is responsible for
the day-to-day management of the material risks we face. Our board of directors administers its cybersecurity risk oversight function directly as a whole, as
well as through the Audit and Risk Committee of our board of directors (“Audit and Risk Committee”).

Our CISO and our Security Steering Committee, which includes members from management across all company functions such as security, IT, human
resources, sales and marketing, engineering, legal, and finance, are primarily responsible for assessing and managing cybersecurity threats. Our CISO is a
cybersecurity industry expert with over two decades of experience in cybersecurity, including work at multi-national technology companies and for a U.S.
state  government.  He  holds  several  industry  certifications  including  CISSP,  OSCP,  CCSP,  and  GCFA  and  is  also  a  graduate  of  the  Carnegie  Mellon
University’s Chief Information Security Officer Executive Program. Our CEO is also a cybersecurity industry expert who has deep insight and over two
decades of experience in cybersecurity, technology and information security.

Our CISO and our Security Steering Committee, along with other senior executives including the CEO and CTO, review and manage our cybersecurity
policies  and  processes,  including  those  described  in  “Risk  Management  and  Strategy”  above.  The  processes  by  which  our  CISO  is  informed  about  and
monitors the prevention, detection, mitigation, and remediation of cybersecurity incidents, include prompt communication from the CSIRT describing the
severity and impact of the incident and status throughout the incident handling lifecycle and routine monitoring of key risk indicators.

Our CISO provides briefings to the Audit and Risk Committee along with our CEO and other members of our senior management team, both on a
quarterly basis via the Qualys Security Steering Committee and as needed, regarding our cybersecurity risks and activities, including, if any, critical and
high impact cybersecurity incidents and related responses, cybersecurity systems testing, activities of third parties, and the emerging threat landscape. Our
Audit and Risk Committee provides regular updates to the board of directors on such reports. In addition, our CISO and management team provide periodic
briefings to the board of directors on cybersecurity risks and activities. Management is committed to notifying the Audit and Risk Committee, and the full
Board in the event of a cyber incident that is confirmed to have a material effect on Qualys, or in the event that Qualys has identified a cyber risk that is
likely to have a high probability of having a material impact on Qualys if not mitigated.

Item 3.     Legal Proceedings

From  time  to  time  we  may  become  involved  in  legal  proceedings  or  be  subject  to  claims  arising  in  the  ordinary  course  of  our  business.  As  of
December  31,  2023,  there  has  not  been  at  least  a  reasonable  possibility  that  we  have  incurred  a  material  loss  from  any  ongoing  legal  proceedings,
individually  or  taken  together.  However,  litigation  is  inherently  unpredictable  and  is  subject  to  significant  uncertainties,  some  of  which  are  beyond  our
control. Should any of these estimates and assumptions change or prove to have been incorrect, we could incur significant charges related to legal matters
which  could  have  a  material  impact  on  its  results  of  operations,  financial  position  and  cash  flows.  For  more  information,  please  refer  to  Note  9  in  the
accompanying notes to the consolidated financial statements, which is hereby incorporated by reference.

Item 7.     Management's Discussion and Analysis of Financial Condition and Results of Operations

You should read the following discussion in conjunction with our consolidated financial statements and the related notes included elsewhere in this
Annual Report on Form 10-K. You should carefully review and consider the information regarding our financial condition and results of operations set
forth under Part II-Item 7 (Management’s Discussion and Analysis of Financial Condition and Results of Operations) in our Annual Report on Form 10-K
for the fiscal year ended December 31, 2022, filed with the SEC on February 23, 2023, for an understanding of our results of operations and liquidity
discussions and analysis comparing fiscal year 2022 to fiscal year 2021, which information is hereby incorporated by reference. In addition to historical
information, this discussion contains forward-looking statements that involve risks and uncertainties that could cause our actual results to differ materially
from  our  expectations,  as  discussed  in  "Forward-Looking  Statements"  in  Part  I  of  this  Annual  Report  on  Form  10-K.  Factors  that  could  cause  such
differences include, but are not limited to, those described in the section titled "Risk Factors" and elsewhere in this Annual Report on Form 10-K.

Overview

We  are  a  pioneer  and  leading  provider  of  a  cloud-based  platform  delivering  information  technology  (IT),  security  and  compliance  solutions  that
enable organizations to identify security risks to their IT infrastructures, help protect their IT systems and applications from ever-evolving cyber-attacks
and achieve compliance with internal policies and external regulations. Our cloud platform address the growing security and compliance complexities and
risks that are amplified by the dissolving boundaries between IT infrastructures and web environments, the rapid adoption of cloud computing, containers
and serverless IT models, and the proliferation of geographically dispersed IT assets. Our integrated suite of IT, security and compliance solutions delivered
on Qualys' Enterprise TruRisk Platform enables our customers to identify and manage their IT and operational technology (OT) assets, collect and analyze
large amounts of IT security data, discover and prioritize vulnerabilities, quantify cyber risk exposure, recommend and implement remediation actions and
verify the implementation of such actions. Organizations use our integrated suite of solutions to cost-effectively obtain a unified view of their internal and
external IT and OT asset inventory as well as security and compliance posture across globally-distributed IT infrastructures as our solution offers a single
platform for information technology, information security, application security, endpoint, developer security and cloud teams.

We were founded and incorporated in December 1999 with a vision of transforming the way organizations secure and protect their IT infrastructure
and  applications  and  initially  launched  our  first  cloud  solution,  Vulnerability  Management  (VM),  in  2000.  As  VM  gained  acceptance,  we  introduced
additional solutions to help customers manage increasing IT, security and compliance requirements. Today, the suite of solutions that we offer on our cloud
platform and refer to as the Qualys Cloud Apps help our customers detect, measure, prioritize and remediate cyber risk spanning a range of assets across
on-premises, endpoints, cloud, containers, and mobile environments.

We  provide  our  solutions  through  a  software-as-a-service  model,  primarily  with  renewable  annual  subscriptions.  These  subscriptions  require
customers to pay a fee in order to access each of our cloud solutions. We generally invoice our customers for the entire subscription amount at the start of
the subscription term, and the invoiced amounts are treated as deferred revenues and are recognized ratably over the term of each subscription. We continue
to  experience  revenue  growth  from  our  existing  customers  as  they  renew  and  purchase  additional  subscriptions,  as  well  as  from  the  addition  of  new
customers to our cloud platform.

We  market  and  sell  our  solutions  to  enterprises,  government  entities  and  small  and  medium-sized  businesses  across  a  broad  range  of  industries,
including education, financial services, government, healthcare, insurance, manufacturing, media, retail, technology and utilities. In 2023, 2022 and 2021,
60%, 60% and 61%, respectively, of our revenues were derived from customers in the United States based on our customers' billing addresses. We sell our
solutions to enterprises and government entities primarily through our field sales force and to small and medium-sized businesses through our inside sales
force.  We  generate  a  significant  portion  of  sales  through  our  channel  partners,  including  managed  security  service  providers,  leading  cloud  providers,
value-added resellers and consulting firms in the United States and internationally.

Impacts of Current Macroeconomic Environment

The uncertainty surrounding macroeconomic factors in the U.S. and globally characterized by the supply chain environment, inflationary pressure,
rising interest rates, financial institution failures and associated uncertainty, labor shortages, significant volatility of global markets, reduced spending and
extended  sales  cycles,  and  geopolitical  conflicts  could  have  a  material  adverse  effect  on  our  long-term  business  and  could  lead  to  further  economic
disruption  and  expose  us  to  greater  risk  as  our  current  and  potential  customers  may  reduce  or  eliminate  their  overall  spending  on  IT  security.  We  will
continue to evaluate the nature and extent of the impact to our business, financial position, results of operations and cash flows.

43

Table of Contents

Key Components of Results of Operations

Revenues

We  derive  revenues  from  the  sale  of  subscriptions  to  our  IT,  security  and  compliance  solutions,  which  are  delivered  on  our  cloud  platform.
Subscriptions  to  our  solutions  allow  customers  to  access  our  cloud-based  IT,  security  and  compliance  solutions  through  a  unified,  web-based  interface.
Customers generally enter into one-year renewable subscriptions. The subscription fee entitles the customer to an unlimited number of scans for a specified
number  of  devices  or  web  applications  and,  if  requested  by  a  customer  as  part  of  their  subscription,  a  specified  number  of  physical  or  virtual  scanner
appliances. Our physical and virtual scanner appliances are requested by certain customers as part of their subscriptions in order to scan IT infrastructures
within their firewalls and do not function without, and are not sold separately from, subscriptions for our solutions. In some cases, we also provide certain
computer equipment used to extend our cloud platform into our customers' private cloud environment. Customers are required to return physical scanner
appliances and computer equipment if they do not renew their subscriptions.

We  typically  invoice  our  customers  for  the  entire  subscription  amount  at  the  start  of  the  subscription  term.  Invoiced  amounts  are  reflected  on  our
consolidated  balance  sheets  as  accounts  receivable  or  as  cash  when  collected,  and  as  deferred  revenues  until  earned  and  recognized  ratably  over  the
subscription  period.  Accordingly,  deferred  revenues  represent  the  amount  billed  to  customers  that  has  not  yet  been  earned  or  recognized  as  revenues,
pursuant to subscriptions entered into in current and prior periods.

Cost of Revenues

Cost  of  revenues  consists  primarily  of  personnel  expenses,  comprised  of  salaries,  benefits,  performance-based  compensation  and  stock-based
compensation, for employees who operate our shared cloud platforms and provide support services to our customers. Other expenses include depreciation
of  shared  cloud  platform  equipment,  physical  scanner  appliances  and  computer  hardware  provided  to  certain  customers  as  part  of  their  subscriptions,
expenses  related  to  the  use  of  shared  cloud  platforms,  amortization  of  software  and  license  fees,  amortization  of  intangibles  related  to  acquisitions,
maintenance support, fees paid to contractors who supplement or support our operations center personnel and overhead allocations. We expect to continue
to expand our shared cloud platform infrastructures and hire additional employees to support our operations, which will increase the cost of revenues in
absolute dollars.

Operating Expenses

Research and Development

Research and development expenses consist primarily of personnel expenses, comprised of salaries, benefits, performance-based compensation and
stock-based  compensation,  for  our  research  and  development  teams.  Other  expenses  include  third-party  contractor  fees,  software  and  license  fees,
amortization of intangibles related to acquisitions and overhead allocations. We expect to continue to devote resources to research and development in an
effort to continuously improve our existing solutions as well as develop new solutions and capabilities and expect that research and development expenses
will increase in absolute dollars.

Sales and Marketing

Sales  and  marketing  expenses  consist  primarily  of  personnel  expenses,  comprised  of  salaries,  benefits,  sales  commissions,  performance-based
compensation  and  stock-based  compensation  for  our  worldwide  sales  and  marketing  teams.  Other  expenses  include  marketing  and  promotional  events,
lead-generation marketing programs, public relations, travel, software licenses and overhead allocations. Sales commissions related to new business and
upsells are capitalized as an asset. We amortize the capitalized commission cost as a selling expense on a straight-line basis over a period of five years. We
expense sales commissions related to contract renewals as incurred. Our new sales personnel are typically not immediately productive, and the resulting
increase in sales and marketing expenses we incur when we add new personnel may not result in increased revenues if these new sales personnel fail to
become  productive.  The  timing  of  our  hiring  of  sales  personnel,  or  the  participation  in  new  marketing  events  or  programs,  and  the  rate  at  which  these
generate incremental revenues, may affect our future operating results. We expect to continue to invest in additional sales personnel worldwide and also in
more marketing programs to support new solutions on our platform, which will increase sales and marketing expenses in absolute dollars.

44

Table of Contents

General and Administrative

General and administrative expenses consist primarily of personnel expenses, comprised of salaries, benefits, performance-based compensation and
stock-based compensation for our executive, finance and accounting, IT, legal and human resources teams, as well as professional services, fees, software
licenses and overhead allocations. We expect that general and administrative expenses will increase in absolute dollars, as we continue to add personnel and
incur professional services to support our growth and compliance with legal requirements.

Other Income (Expense), Net

Our other income (expense), net consists primarily of interest and returns from our short-term and long-term marketable securities, non-marketable

securities gains and losses, and foreign exchange gains and losses.

Income Tax Provision

We are subject to federal, state and foreign income taxes for jurisdictions in which we operate, and we use estimates in determining our income tax
provision  and  deferred  tax  assets.  Earnings  from  our  non-U.S.  activities  are  subject  to  income  taxes  in  the  local  countries  at  rates  which  are  generally
similar to the U.S. statutory tax rate. We regularly assess the realizability of our net deferred tax assets. As of December 31, 2023, valuation allowances
remain in certain jurisdictions where we believe it is necessary to see further positive evidence, such as sustained achievement of sufficient profits to meet a
more likely than not stance that the valuation allowance should be reversed. If additional positive evidence becomes available in the foreseeable future, we
may release all or a portion of the valuation allowance. The exact timing and amount of the valuation allowance release is subject to change based on the
level  of  profitability  achieved  in  future  periods.  Release  of  the  valuation  allowance  would  result  in  the  recognition  of  deferred  tax  assets  and  a
corresponding decrease to income tax expense in the period the release is recorded.

General and administrative expenses increased by $3.8 million in 2023 compared to 2022, due to an increase in personnel costs, including stock-
based compensation of $5.7 million, driven by increased headcount, annual merit increases for eligible employees and refresh grants to eligible employees
and executives, and an increase in subscribed license and software cost of $0.8 million, partially offset by a decrease in professional service expense of $1.4
million, and a decrease in legal expense of $1.3 million.

On July 21, 2023, the IRS issued a rule change allowing taxpayers to temporarily apply the regulations in effect prior to 2022 related to U.S. federal
foreign tax credits to foreign taxes paid or accrued in years 2022 and 2023. Additionally, on September 8, 2023, the IRS issued interim guidance on the
capitalization  and  amortization  of  research  and  development  expenses.  A  cumulative  tax  benefit  applicable  to  prior  periods  for  the  rule  change  and  the
guidance was recorded in 2023, which reduced the effective tax rate in 2023 compared to 2022. On December 11, 2023, the IRS extended the temporary
relief for U.S. Federal foreign tax credit until further guidance, which is expected to provide similar tax benefits in future tax years.

Income tax provision increased by $1.3 million in 2023 compared to 2022, primarily due to an increase in pretax income and a decrease in excess
tax benefits arising from stock-based compensation compared to the same period in 2022. The increase was partially offset by higher foreign tax credits and
lower net capitalization of research and development expenses for tax purposes than previously estimated, reflecting the rule change and the guidance.

Key Operating and Non-GAAP Financial Performance Metrics

In addition to measures of financial performance presented in our consolidated financial statements, we monitor the key metrics set forth below to

help us evaluate growth trends, establish budgets, measure the effectiveness of our sales and marketing efforts and assess operational efficiencies.

Net Dollar Expansion Rate

We evaluate our ability to retain and grow existing customers by assessing our net dollar expansion rate on a last twelve months, or LTM, basis. This
metric is used to appropriately manage resources and customer retention and expansion. We calculate the net dollar expansion rate on a foreign exchange
neutral basis by dividing a numerator by a denominator, each defined as follows:

Denominator: To calculate our net dollar expansion rate as of the end of a reporting period, we first determine the annual recurring revenue, or ARR,
from all active subscriptions as of the last day of the same reporting period in the prior year. This represents recurring payments that we expect to receive in
the next 12-month period from the cohort of customers that existed on the last day of the same reporting period in the prior year.

Numerator: We measure the ARR for that same cohort of customers representing all active subscriptions as of the end of the reporting period, using

the same foreign exchange rate from the prior year.

Our net dollar expansion rates were 105% and 109% for the years ended December 31, 2023 and 2022, respectively.

Adjusted EBITDA

We  monitor  Adjusted  EBITDA,  a  non-GAAP  financial  measure,  to  analyze  our  financial  results  and  believe  that  it  is  useful  to  investors,  as  a
supplement  to  U.S.  GAAP  measures,  in  evaluating  our  ongoing  operational  performance  and  enhancing  an  overall  understanding  of  our  past  financial
performance.  We  believe  that  Adjusted  EBITDA  helps  illustrate  underlying  trends  in  our  business  that  could  otherwise  be  masked  by  the  effect  of  the
income or expenses that we exclude in Adjusted EBITDA. Furthermore, we use this measure to establish budgets and operational goals for managing our
business  and  evaluating  our  performance.  We  also  believe  that  Adjusted  EBITDA  provides  an  additional  tool  for  investors  to  use  in  comparing  our
recurring core business operating results over multiple periods with other companies in our industry.

48

Table of Contents

Adjusted EBITDA should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with U.S. GAAP.
We calculate Adjusted EBITDA as net income before (1) other (income) expense, net, which includes interest income, interest expense and other income
and  expense,  (2)  income  tax  provision  (benefit),  (3)  depreciation  and  amortization  of  property  and  equipment,  (4)  amortization  of  intangible  assets,  (5)
stock-based compensation and (6) non-recurring expenses that do not reflect ongoing costs of operating the business.

Adjusted EBITDA has limitations as an analytical tool and should not be considered in isolation from or as a substitute for the measures presented in

accordance with U.S. GAAP. Some of these limitations are:

• Adjusted EBITDA does not reflect certain cash and non-cash charges that are recurring;

• Adjusted EBITDA does not reflect income tax payments that reduce cash available to us;

• Adjusted EBITDA excludes depreciation and amortization of property and equipment and amortization of intangible assets, although these are

non-cash charges, the assets being depreciated and amortized may have to be replaced in the future; and

• Other companies, including companies in our industry, may calculate Adjusted EBITDA differently or not at all, which reduces its usefulness as

a comparative measure.

Because  of  these  limitations,  Adjusted  EBITDA  should  be  considered  alongside  other  financial  performance  measures,  including  revenues,  net

income, cash flows from operating activities and our financial results presented in accordance with U.S. GAAP.

The following unaudited table presents the reconciliation of net income to Adjusted EBITDA for the years ended December 31, 2023 and 2022.

Operating Activities

In  2023,  we  generated  $226.4 million  of  cash  from  our  net  income,  as  adjusted  for  non-cash  items  mainly  related  to  stock-based  compensation
expense, depreciation and amortization expense and deferred taxes, as compared to $177.2 million in 2022. In addition, we also generated $18.2 million of
cash from working capital change in 2023, of which $22.7 million was related to a net increase in deferred revenue and accounts receivable due to the
growth in billing and the timing of collections, partially offset by a $1.1 million decrease in payables and accrued liabilities and a $3.4 million increase in
prepaid expenses primarily driven by the timing of payments. In 2022, we generated $177.2 million of cash from our net income, as adjusted for non-cash
items mainly related to stock-based compensation expense, depreciation and amortization expense and deferred taxes, as compared to $169.6 million in
2021. In addition, we also generated $21.7 million of cash from working capital change in 2022, of which $11.8 million was related to a net increase in
deferred revenue and accounts receivable as a result of our continued growth in billing and the timing of collections, and $9.9 million was due to lower
prepaid expenses and an increase in payables and accrued liabilities primarily due to timing of payments.

Investing Activities

In 2023, we used $64.4 million of cash for purchases of marketable securities net of sales and maturities, and used $8.8 million of cash in capital
expenditures mainly related to computer equipment to support our growth and development, as compared to $169.0 million of cash generated from net
sales and maturities of our marketable securities, $15.4 million of cash used in capital expenditures mainly related to computer equipment to support our
growth and development and $8.6 million of cash used to acquire certain technology assets in 2022.

Financing Activities

In 2023, we used $170.8 million of cash for share repurchase and $22.3 million of cash in payment of employee withholding taxes upon vesting of
restricted stock units, partially offset by $45.6 million of proceeds from employee exercise of stock options and $6.1 million of proceeds from issuance of
common stock through our employee stock purchase plan ("ESPP"), as compared to $317.3 million of cash used for share repurchase and $17.6 million of
cash in payment of employee withholding taxes upon vesting of restricted stock units, partially offset by $24.5 million of proceeds from employee exercise
of stock options and $4.4 million of proceeds from issuance of common stock through our ESPP in 2022.

Material Cash Requirements

We believe our existing cash and cash equivalents, marketable securities and our expected cash flow generated from operations will be sufficient to
fund our operations for the next twelve months and beyond. If we repatriate funds from our foreign subsidiaries, we could be subject to foreign withholding
taxes.

Our material cash requirements mainly include the following contractual and other obligations:

• Our operating lease obligations to make payments under our non-cancelable lease agreements for our facilities and shared cloud platforms.
We had fixed operating lease payment obligations of $31.1 million as of December 31, 2023, with $13.1 million expected to be paid within
the next 12 months.
Cash outflow for capital expenditures in 2024 is expected to be in a range of $15.0 million to $20.0 million. Our future capital requirements
will depend on many factors, including our rate of revenue growth, the expansion of our sales and marketing activities, the timing, type and
extent of our spending on research and development efforts, international expansion and investment in shared cloud platforms and cloud
infrastructures. We may also seek to invest in or acquire complementary businesses or technologies.

•

• Other non-cancelable purchase obligations related to cloud infrastructures and other service providers totaled $70.6 million, of which $29.7

million is expected to be paid within the next 12 months.

Share Repurchases

We expect to continue to use cash to repurchase shares in 2024 under our share repurchase program authorized by our board of directors on February
5, 2018. As of December 31, 2023, our board of directors had authorized an aggregate amount of $1.0 billion for repurchases under our share repurchase
program, of which approximately $83.7 million remained available. Shares will be repurchased from time to time in the open market in accordance with
Rule 10b-18 of the Exchange Act of 1934, including pursuant to a pre-set trading plan adopted in accordance with Rule 10b5-1 under the Exchange Act.

50

Table of Contents

On  February  7,  2024,  we  announced  that  our  Board  of  Directors  authorized  an  additional  $200.0  million  under  the  share  repurchase  program,

increasing the total amount of authorized repurchase to $1.2 billion.

Critical Accounting Estimates

The preparation of our consolidated financial statements in accordance with U.S. GAAP requires us to make estimates and assumptions that affect
the reported amounts of assets, liabilities, revenues, expenses and related disclosures. Our significant accounting policies are described in Note 1 - The
Company and Summary of Significant Accounting Policies in the accompanying notes to the consolidated financial statements included in Part II, Item 8,
"Financial Statements and Supplementary Data" of this Annual Report on Form 10-K. On an ongoing basis, we evaluate our estimates and assumptions
based on historical and anticipated results and trends that we believe represent our best estimate under the circumstances. However, as accounting estimates
are subject to inherent uncertainty, our actual results may differ from these estimates under different assumptions or conditions.

Income Taxes

Significant assumptions, judgments and estimates are involved in determining our provision for (benefit from) income taxes, our deferred tax assets
and liabilities, and any valuation allowance to be recorded against our deferred tax assets. Our judgments, assumptions and estimates relating to the current
provision for income taxes include the geographic mix and amount of income (loss), expectations of future income, our interpretation of current tax laws,
our business, and possible outcomes of current and future audits conducted by foreign and domestic tax authorities. Our judgments also include anticipating
the tax positions we will record in the financial statements before preparing and filing the tax returns. Our estimates and assumptions may differ from the
actual results as reflected in our income tax returns and we record the required adjustments when they are identified or resolved. Changes in our business
and tax laws or our interpretation of those, and developments in current and future tax audits, could significantly impact the amounts provided for income
taxes in our results of operations, financial position, or cash flows.

The assessment of tax effects of our uncertain tax positions in our financial statements involves significant judgment in interpreting complex and
ambiguous tax laws, regulations, and administrative practices, determining the probability of various possible settlement outcomes, evaluating the litigation
process  based  on  tax  authority  behaviors  in  similar  cases,  and  estimating  the  likelihood  that  another  taxing  authority  could  review  the  respective  tax
position.  These  judgments  are  inherently  challenging  and  subjective  because  a  taxing  authority  may  change  its  behavior  at  any  time.  We  must  also
determine when it is reasonably possible that the amount of unrecognized tax benefits will significantly increase or decrease in the 12 months after each
fiscal year-end. We reevaluate our income tax positions on a quarterly basis to consider factors such as changes in facts or circumstances, changes in tax
laws, effectively settled issues under audit, the potential for interest and penalties, and new audit activity. Such a change in recognition or measurement
would result in recognition of a tax benefit or an additional charge to the tax provision that could be material in the future.

Stock-Based Compensation

We recognize the fair value of our employee stock options and restricted stock units, including performance-based restricted stock units, over the
requisite  service  period.  The  fair  value  of  each  stock  option  is  estimated  on  date  of  grant  using  the  Black-Scholes-Merton  option  pricing  model.
Determining the appropriate fair value model and calculating the fair value of employee stock options requires the use of subjective assumptions, including
the  expected  life  of  the  stock  option  and  stock  price  volatility.  The  recognition  of  expenses  for  performance  based  restricted  stock  units  requires  us  to
estimate the probability that the performance condition will be achieved and the number of awards that will vest are adjusted accordingly at each reporting
period. The assumptions used in calculating the fair value of employee stock options and estimating the probability of achievement of performance metrics
represent  management’s  best  estimates,  which  require  significant  judgment  and  involve  inherent  uncertainties.  If  factors  change  and  we  use  different
assumptions, our stock-based compensation expense could be materially different in the future.

Item 7A.     Quantitative and Qualitative Disclosures about Market Risk

We  have  domestic  and  international  operations  and  we  are  exposed  to  market  risks  in  the  ordinary  course  of  our  business.  These  risks  primarily
include interest rate, foreign exchange and inflation risks, as well as risks relating to changes in the general economic conditions in the countries where we
conduct  business.  To  reduce  certain  of  these  risks,  we  monitor  the  financial  condition  of  our  large  customers  and  limit  credit  exposure  by  collecting
subscription fees in advance.

51

Table of Contents

Foreign Currency Risk

Our results of operations and cash flows have been and will continue to be subject to fluctuations because of changes in foreign currency exchange
rates, particularly changes in exchange rates between the U.S. Dollar and the EUR, GBP, INR and Canadian Dollar ("C$" or "CAD"), the currencies of
countries where we currently have our most significant international operations. We enter into foreign currency forward contracts to reduce our exposure to
foreign  currency  exchange  rate  fluctuations  related  to  forecasted  subscription  revenue,  operating  expenses  and  foreign  currency  denominated  assets  or
liabilities. As  of  December  31,  2023,  we  had  designated  cash  flow  hedge  forward  contracts  with  notional  amounts  of  €48.5  million, £14.6  million  and
Rs.4,042.0 million and non-designated forward contracts with notional amounts of €19.2 million, £6.0 million, Rs.440.0 million and C$1.0 million. With
our hedging strategy applied, the effect of an immediate 10% adverse change in foreign exchange rates would not be material to our financial condition,
operating results or cash flows.

Interest Rate Sensitivity

We  had  $482.2 million  in  cash,  cash  equivalents  and  short-term  and  long-term  marketable  securities  as  of  December  31,  2023.  Our  exposure  to
market risk for changes in interest rates primarily relates to our cash and cash equivalents and marketable securities. Our cash equivalents and marketable
securities are held in money market funds, fixed-income U.S. Treasury and government agency securities, commercial paper, corporate bonds and asset-
backed securities. The primary objectives of our investment activities are the preservation of principal and support of our liquidity requirements. We do not
invest for trading or speculative purposes. Our marketable securities are subject to market risk due to changes in interest rates, which may affect the interest
income we earn and the fair market value. As of December 31, 2023, a hypothetical 100 basis point increase in interest rate would result in a decrease in
the fair value of our marketable securities by $1.4 million.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders

Qualys, Inc.

Opinion on the financial statements
We  have  audited  the  accompanying  consolidated  balance  sheets  of  Qualys,  Inc.  (a  Delaware  corporation)  and  subsidiaries  (the  “Company”)  as  of
December 31, 2023 and 2022, the related consolidated statements of operations, comprehensive income, stockholders’ equity, and cash flows for each of
the three years in the period ended December 31, 2023, and the related notes (collectively referred to as the “financial statements”). In our opinion, the
financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its
operations  and  its  cash  flows  for  each  of  the  three  years  in  the  period  ended  December  31,  2023,  in  conformity  with  accounting  principles  generally
accepted in the United States of America.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the Company’s
internal control over financial reporting as of December 31, 2023, based on criteria established in the 2013 Internal Control—Integrated Framework issued
by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”), and our report dated February 22, 2024, expressed an unqualified
opinion.

Basis for opinion
These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial
statements  based  on  our  audits.  We  are  a  public  accounting  firm  registered  with  the  PCAOB  and  are  required  to  be  independent  with  respect  to  the
Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the
PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable
assurance  about  whether  the  financial  statements  are  free  of  material  misstatement,  whether  due  to  error  or  fraud.  Our  audits  included  performing
procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to
those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits
also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the
financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical audit matters
Critical audit matters are matters arising from the current period audit of the financial statements that were communicated or required to be communicated
to  the  audit  committee  and  that:  (1)  relate  to  accounts  or  disclosures  that  are  material  to  the  financial  statements  and  (2)  involved  our  especially
challenging, subjective, or complex judgments. We determined that there are no critical audit matters.

Report of Independent Registered Public Accounting Firm

Opinion on internal control over financial reporting
We  have  audited  the  internal  control  over  financial  reporting  of  Qualys,  Inc.  (a  Delaware  corporation)  and  subsidiaries  (the  “Company”)  as  of
December  31,  2023,  based  on  criteria  established  in  the  2013  Internal  Control—Integrated  Framework  issued  by  the  Committee  of  Sponsoring
Organizations of the Treadway Commission (“COSO”). In our opinion, the Company maintained, in all material respects, effective internal control over
financial reporting as of December 31, 2023, based on criteria established in the 2013 Internal Control—Integrated Framework issued by COSO.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the consolidated
financial statements of the Company as of and for the year ended December 31, 2023, and our report dated February 22, 2024 expressed an unqualified
opinion on those financial statements.

Basis for opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of
internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our
responsibility  is  to  express  an  opinion  on  the  Company’s  internal  control  over  financial  reporting  based  on  our  audit.  We  are  a  public  accounting  firm
registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable
assurance  about  whether  effective  internal  control  over  financial  reporting  was  maintained  in  all  material  respects.  Our  audit  included  obtaining  an
understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating
effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We
believe that our audit provides a reasonable basis for our opinion.

Definition and limitations of internal control over financial reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting
and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control
over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly
reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit
preparation  of  financial  statements  in  accordance  with  generally  accepted  accounting  principles,  and  that  receipts  and  expenditures  of  the  company  are
being  made  only  in  accordance  with  authorizations  of  management  and  directors  of  the  company;  and  (3)  provide  reasonable  assurance  regarding
prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial
statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of
effectiveness  to  future  periods  are  subject  to  the  risk  that  controls  may  become  inadequate  because  of  changes  in  conditions,  or  that  the  degree  of
compliance with the policies or procedures may deteriorate.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1.     The Company and Summary of Significant Accounting Policies

Description of Business

Qualys, Inc. (the “Company”, "we", "us", "our") was incorporated in the state of Delaware on December 30, 1999. The Company is headquartered in
Foster  City,  California  and  has  wholly-owned  subsidiaries  throughout  the  world.  The  Company  is  a  leading  provider  of  cloud-based  IT,  security  and
compliance solutions that enable organizations to identify security risks to their IT infrastructures, help protect their IT systems and applications from ever-
evolving cyber-attacks and achieve compliance with internal policies and external regulations. The Company’s cloud solutions address the growing security
and  compliance  complexities  and  risks  that  are  amplified  by  the  dissolving  boundaries  between  internal  and  external  IT  infrastructures  and  web
environments,  the  rapid  adoption  of  cloud  computing  and  the  proliferation  of  geographically  dispersed  IT  assets.  Organizations  can  use  the  Company’s
integrated suite of solutions delivered on Qualys' Enterprise TruRisk Platform to cost-effectively obtain a unified view of their security and compliance
posture across globally-distributed IT infrastructures.

Basis of Presentation

The accompanying consolidated financial statements and footnotes have been prepared in accordance with U.S. GAAP as well as the instructions to
Form 10-K and the rules and regulations of the SEC. Certain prior year amounts have been reclassified to conform with the current year presentation. In the
opinion  of  management,  the  accompanying  consolidated  financial  statements  reflect  all  adjustments,  which  include  only  normal  recurring  adjustments,
necessary for the fair presentation of the Company’s consolidated financial position, results of operations and cash flows for the periods presented. The
accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions
and balances have been eliminated upon consolidation.

Use of Estimates

The  preparation  of  the  consolidated  financial  statements  in  conformity  with  U.S.  GAAP  requires  management  to  make  certain  estimates  and
assumptions  that  affect  the  reported  amounts  of  assets  and  liabilities  and  disclosure  of  assets  and  liabilities  at  the  date  of  the  consolidated  financial
statements  and  the  reported  results  of  operations  during  the  reporting  period.  The  Company’s  management  regularly  assesses  these  estimates,  which
primarily  affect  revenue  recognition,  allowance  for  credit  loss,  the  valuation  of  goodwill  and  intangible  assets,  leases,  stock-based  compensation  and
income tax provision. Actual results could differ from those estimates and such differences may be material to the accompanying consolidated financial
statements.

Concentration of Credit Risk

The  Company  invests  its  cash  and  cash  equivalents  with  major  financial  institutions.  Cash  balances  with  any  one  institution  at  times  may  be  in
excess of federally insured limits. Cash equivalents are invested in high-quality investment grade financial instruments and are diversified. The Company
has not experienced any losses in such accounts and believes it is not exposed to any significant credit risk.

Credit risk with respect to accounts receivable is dispersed due to the large number of customers. Collateral is not required for accounts receivable.
As of December 31, 2023 and 2022, no customer or channel partner accounted for more than 10% of the Company's revenues and accounts receivable
balance.

Cash, Cash Equivalents, Restricted cash and Short-Term and Long-Term Marketable Securities

Cash and cash equivalents include cash held in banks, highly liquid money market funds, and fixed-income U.S. Treasury and government agencies,
all with original maturities of three months or less when acquired. The Company’s short-term and long-term marketable securities consist of fixed-income
U.S. and foreign government agency securities, corporate bonds, asset-backed securities and commercial paper. Management determines the appropriate
classification of the Company's investments at the time of purchase and reevaluates such designation at each balance sheet date. The Company classifies its
marketable securities as either short-term or long-term based on each instrument's underlying remaining contractual maturity date.

61

Table of Contents

As of December 31, 2023 and 2022, the Company had a restricted cash balance of $2.7 million, of which $1.5 million is related to cash held in
escrow  as  part  of  the  Blue  Hexagon  acquisition  and  $1.2  million  in  the  form  of  a  letter  of  credit  issued  to  the  landlord  of  the  Company's  California
headquarter office lease as security deposit.

Cash equivalents are stated at cost, which approximates fair market value. Short-term and long-term marketable securities are classified as available-
for-sale debt securities (AFS debt securities) and are carried at fair value. Unrealized gains and losses in fair value of the AFS debt securities are reported in
other comprehensive income (loss). When the AFS debt securities are sold, cost is based on the specific identification method, and the realized gains and
losses are included in other income (expense), net in the consolidated statements of operations. AFS debt securities are reviewed quarterly for impairment.
An investment is considered impaired when its fair value is below its amortized cost. Declines in fair value from amortized cost for AFS debt securities that
the company intends to sell or will more likely than not be required to sell before the expected recovery of the amortized cost basis are charged to other
income (expense), net in the period in which the loss occurs. Otherwise, the credit loss component of the impairment is recorded as allowance for credit
losses with an offsetting entry charged to other income (expense), net, while the remaining loss is recognized in other comprehensive income (loss).

Accounts Receivable

Accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for credit losses is determined on a collective basis
where similar risk characteristics exist and on an individual basis when the Company identifies significant customers or invoices with collectability issues.
The  estimate  for  credit  losses  considers  historical  write-offs  by  aging  category,  that  are  adjusted  for  current  conditions  and  reasonable  and  supportable
forecasts of future losses. Any change in the assumptions used in analyzing credit losses may result in additional allowances being recognized in the period
in which the change occurs. When the Company ultimately concludes that a receivable is uncollectible, the balance is written off against the allowance for
credit losses. Payments subsequently received on such receivables are recognized in the period received. The allowance for credit losses recognized and
write-offs charged against the allowance were not significant for the years ended December 31, 2023 and 2022. The balance of accounts receivable, net of
allowance for credit losses was $146.2 million, $121.8 million and $109.0 million as of December 31, 2023, December 31, 2022 and December 31, 2021,
respectively.

Non-marketable securities

In 2018, the Company invested $2.5 million in preferred stock of a privately-held company (the “Investee”). The fair value of the investment is not
readily available, and there are no quoted market prices for the investment. The Company elected the measurement alternative to account for the investment
at cost less impairment and will measure the investment at fair value when the Company identifies observable price changes. The investment is assessed for
impairment  annually  or  whenever  events  or  changes  in  circumstances  indicate  that  the  fair  value  of  the  investment  is  less  than  carrying  value.  The
investment is included in other noncurrent assets in the consolidated balance sheets. The Company has not received any dividends from the investment.
During the second quarter of 2023, the Company identified an observable price change in the investment and recognized an immaterial unrealized loss in
other income (expense), net of the consolidated statement of operations.

In  2019,  the  Company  made  an  advance  payment  of  $0.6  million  to  the  Investee  for  it  to  perform  certain  technology  development  work,  which
should either be settled in the form of royalty fee charges when the technology materializes and is licensed to the Company or, otherwise, should be repaid
to the Company in cash. The advance payment was recorded in other non-current assets in the consolidated balance sheet. During the fourth quarter ended
December  31,  2021,  the  technology  has  not  been  developed  and  the  Company  decided  to  no  longer  pursue  the  development  of  the  technology  or  the
collection of the advanced amount. Accordingly, the entire amount of the advance payment was written off and recorded in the general and administrative
expense during the year ended December 31, 2021.

Property and Equipment, net

Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is computed using the straight-line method
over the estimated useful lives of the assets, which range from three to five years. Leasehold improvements are amortized on a straight-line basis over the
lesser of the estimated useful life of the asset or the remaining lease term.

The Company purchases physical scanner appliances and other computer equipment that are provided to some customers on a subscription basis.

This equipment is recorded within property and equipment and the depreciation is recorded in cost of revenues over an estimated useful life of three years.

62

Table of Contents

Upon retirement or disposal, the cost of assets and the related accumulated depreciation are removed from the accounts and any resulting gain or loss
is reflected in the consolidated statements of operations. Repairs and maintenance that do not extend the life of an asset are expensed as incurred and major
improvements are capitalized as property and equipment.

Leases

The Company leases certain offices, computer equipment and its shared cloud platform facilities under finance leases and non-cancelable operating
leases. For both operating and finance leases, the Company recognizes a right-of-use asset, which represents the Company's right to use the underlying
asset for the lease term, and a lease liability, which represents the present value of the Company's obligation to make payments arising over the lease term.
Many  of  the  Company's  leases  include  rental  escalation  clauses,  renewal  options  and/or  termination  options  that  are  factored  into  the  Company's
determination of lease payments and lease terms when appropriate. The present value of the lease payments is calculated using the incremental borrowing
rate of the underlying leases determined at lease commencement. As most of the Company's leases do not provide a readily determinable implicit rate, the
Company determines an incremental borrowing rate using a portfolio approach based on the rate of interest that the Company would have to pay to borrow
an amount equal to the lease payments on a collateralized basis over a similar term as the leases.

Where  the  Company  is  the  lessee,  the  Company  elects  to  account  for  non-lease  components  associated  with  its  leases  (e.g.,  common  area
maintenance costs) and lease components separately for substantially all of its asset classes, except for shared cloud platforms, for which the Company
elected to combine lease and non-lease components. For leases with a term of one year or less, the Company has elected not to record the right-of-use asset
or liability.

In  arrangements  where  the  Company  is  the  lessor,  the  Company  elected  to  apply  the  practical  expedient  to  account  for  lease  components  (e.g.,
customer premise equipment) and non-lease components (e.g., service revenue) as combined components as revenue under ASC 606 as service revenues
are the predominant components in the arrangements.

Impairment of Long-Lived Assets

The Company evaluates its long-lived assets, which consist of property and equipment, and intangible assets subject to amortization, for indicators
of possible impairment when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Impairment exists if the
carrying amounts of such assets exceed the estimates of future undiscounted cash flows expected to be generated by such assets. Should an impairment
exist, the impairment loss would be measured based on the excess carrying value of the asset over the asset’s estimated fair value. For the years ended
December 31, 2023, 2022 and 2021, there was no impairment of long-lived assets.

Goodwill and Intangible Assets

Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in a business
combination.  Goodwill  and  indefinite-lived  intangible  assets  are  not  amortized  but  tested  for  impairment  at  least  annually  or  more  frequently  if  certain
circumstances  indicate  a  possible  impairment  may  exist.  The  goodwill  impairment  tests  are  performed  at  the  reporting  unit  level.  The  Company’s
operations are organized as one reporting unit.

In testing for a potential impairment of goodwill and the indefinite-lived intangible assets, the Company first performs a qualitative assessment to
determine if it is more likely than not (a more than 50% likelihood) that the fair value of the reporting unit or the indefinite-lived intangible assets is less
than  their  carrying  amount.  If  the  fair  value  is  not  considered  to  be  less  than  the  carrying  amount,  no  further  evaluation  is  necessary.  Otherwise,  the
Company  will  perform  a  quantitative  test.  Goodwill  impairment  is  measured  as  the  amount  by  which  the  carrying  value  of  the  reporting  unit  or  the
indefinite-lived intangible assets exceeds their fair value. The Company performed the annual assessments on December 1, 2023 and 2022 and concluded
there was no impairment of goodwill or the indefinite-lived intangible assets.

Software Development Costs

The  costs  to  develop  software  that  is  marketed  externally  have  not  been  capitalized  as  the  Company  believes  its  current  software  development
process  is  essentially  completed  concurrent  with  the  establishment  of  technological  feasibility.  As  such,  all  related  software  development  costs  are
expensed as incurred and included in research and development expense on the Company's consolidated statements of operations.

63

Table of Contents

Costs related to software developed, acquired or modified for internal use are capitalized and included in other noncurrent assets on the consolidated
balance sheets. Costs incurred during the preliminary planning and evaluation stage of the project and during the post implementation stages of the project
are expensed as incurred. Costs incurred during the application development stage of the project are capitalized. These capitalized costs consist of internal
compensation related costs and external direct costs. Costs related to software developed for internal use are amortized over an estimated useful life of three
years and recorded in cost of revenues. Management evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events
or changes in circumstances occur that could impact the recoverability of these assets. As of December 31, 2023 and 2022, unamortized balances related to
the Company's internally developed software costs are immaterial.

Asset Acquisitions and Business Combinations

The  Company  applies  the  provisions  of  ASC  805,  Business  Combinations,  in  accounting  for  its  acquisitions.  To  determine  whether  transactions
should  be  accounted  for  as  asset  acquisition  or  business  combination,  the  Company  evaluates  whether  substantially  all  of  the  fair  value  of  gross  assets
included  in  a  transaction  is  concentrated  in  a  single  asset  (or  a  group  of  similar  assets),  resulting  in  an  asset  acquisition,  if  not,  resulting  in  a  business
combination.  In  an  asset  acquisition,  the  cost  of  acquiring  the  asset  group,  including  transaction  costs,  is  allocated  to  the  acquired  assets  or  assumed
liabilities based on their relative fair values without giving rise to goodwill. In a business combination, the Company recognize separately from goodwill
the  assets  acquired  and  the  liabilities  assumed  at  their  acquisition  date  fair  values.  Goodwill  as  of  the  acquisition  date  is  measured  as  the  excess  of
consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. While the Company uses its best
estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date as well as any contingent consideration, where
applicable, its estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from
the acquisition date, the Company records adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the
conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent
adjustments are recorded to its consolidated statements of operations.

Derivative Financial Instruments

Derivative  financial  instruments  are  utilized  by  the  Company  to  reduce  foreign  currency  exchange  risks.  The  Company  uses  foreign  currency
forward contracts, with maturities of 13 months or less, to mitigate the impact of foreign currency fluctuations of certain non-U.S. dollar denominated net
asset positions, to date primarily cash, accounts receivable and operating lease liabilities, as well as to manage foreign currency fluctuation risk related to
forecasted transactions. Open contracts are recorded within prepaid expenses and other current assets, other noncurrent assets, accrued liabilities or other
noncurrent liabilities in the consolidated balance sheets. Gains and losses resulting from currency exchange rate movements on non-designated forward
contracts  are  recognized  in  other  income  (expense),  net.  Any  gains  or  losses  from  derivatives  designated  as  cash  flow  hedges  are  first  recorded  within
accumulated  other  comprehensive  income  (“AOCI”)  and  then  reclassified  into  revenue  or  operating  expenses  when  the  hedged  item  impacts  the
consolidated statements of operations. Cash flows related to these forward contracts are classified in the Company's consolidated statements of cash flows
in the same manner as the underlying hedged transaction within cash flows from operating activities.

Stock-Based Compensation

The Company recognizes the fair value of its stock options, restricted stock units (“RSUs”) and stock purchase rights under the ESPP on a straight-
line basis over the requisite service periods. The fair value of each stock option or stock purchase right is estimated on the date of grant using the Black-
Scholes-Merton option pricing model and the fair value of each RSU is based on the Company's common stock price on the date of grant. Compensation
expenses  for  performance-based  stock  options  (“PSOs”)  and  performance-based  restricted  stock  units  (“PSUs”)  are  recorded  based  on  expected
achievement of the performance metrics specified in the grant, which are assessed on a quarterly basis. Forfeitures are estimated on the date of grant and
revised if actual or expected forfeiture materially differs from original estimates.

Revenue Recognition

The Company derives revenues from subscriptions that require customers to pay a fee in order to access the Company’s cloud solutions. Contract
period with customers generally are one year with occasional contracts ranging up to five years. The subscription fee entitles the customer to an unlimited
number of scans for a specified number of networked devices or web applications and, if requested by a customer as part of their subscription, a specified
number of physical or virtual scanner appliances. The Company’s physical and virtual scanner appliances are requested by certain customers as part of their
subscriptions in order to scan IT infrastructures within their firewalls and do not function without, and are not sold separately from, subscriptions for the
Company’s solutions. In some limited cases, the Company also provides certain computer equipment used to extend Qualys' Enterprise TruRisk Platform
into its customers’ private cloud environment. Customers are required to return physical scanner appliances and computer equipment if they do not renew
their subscriptions.

The Company determines revenue recognition through the following steps:

•

•

Identification of the contract, or contracts, with a customer;

Identification of the performance obligations in the contract;

• Determination of the transaction price;

• Allocation of the transaction price to the performance obligations in the contract; and

•

Recognition of revenue when, or as, the Company satisfies a performance obligation.

At  the  inception  of  a  customer  contract,  the  Company  makes  an  assessment  as  to  that  customer's  ability  to  pay  for  the  services  provided.  The
Company assesses collectability based on several factors, including credit worthiness of the customer along with past transaction history. In addition, the
Company performs periodic evaluations of its customers’ financial condition.

Most of the Company’s revenue contracts are subscription based and contain a single performance obligation. The subscription contracts typically do
not  offer  to  the  customers  any  future  rights  that  would  constitute  material  rights.  Contract  prices  are  generally  composed  of  fixed  consideration  for  a
specific period of time as the Company in general does not offer refunds, volume rebates, customer loyalty programs or other forms of customer incentive
payments. In limited situations, contract prices are contingent on future events, such as actual usage during the contract terms, which are accounted for as
variable  consideration  and  estimated  based  on  the  most  likely  amount  of  consideration  that  the  Company  is  expected  to  be  entitled  to.  Estimates  are
included in the contract price to the extent that it is considered probable that a significant reversal in the amount of cumulative revenue recognized will not
occur when the uncertainty associated with the variable consideration is subsequently resolved. Such estimates are made at contract inception and updated
periodically when additional information becomes available. A cumulative catch-up adjustment is made when there is a change in the estimate of variable
consideration.

As the Company's cloud-based subscription services are delivered to customers electronically and over time, revenue is generally recognized ratably
over  the  contract  terms.  When  physical  equipment  is  provided  to  the  customers  as  part  of  the  subscription  service  contract,  the  Company  applies  the
practical expedient allowed under ASC 842 Leases to combine lease and nonlease components as a combined component to be accounted for under ASC
606,  as  the  Company  determined  that  the  software  subscription  is  the  predominant  component  of  the  combined  components.  Therefore,  the  Company
recognizes revenue for the physical equipment ratably over the related subscription period.

Contract  modifications  happen  when  there  is  an  upsell,  where  the  customers  subsequently  enter  into  contract  with  the  Company  to  purchase

additional product offerings or additional scans for additional devices. Contract modifications related to upsells are accounted for prospectively.

Deferred  revenues  consist  of  customer  contracts  billed  or  cash  received  that  will  be  recognized  in  the  future  under  subscriptions  existing  at  the
balance sheet date. The current portion of deferred revenues represents amounts that are expected to be recognized within one year of the balance sheet
date.

Costs of shipping and handling charges incurred by the Company associated with physical scanner appliances and other computer equipment are

included in cost of revenues. Sales taxes and other taxes collected from customers to be remitted to government authorities are excluded from revenues.

65

Table of Contents

Incremental  direct  costs  of  obtaining  a  contract,  which  consist  of  sales  commissions  primarily  for  new  business  and  upsells,  are  deferred  and
amortized over the estimated life of the customer relationship if renewals are expected and the renewal commission is not commensurate with the initial
commission. The Company elected the practical expedient to expense commissions on renewals where the specific anticipated contract term amortization
period is one year or less. The Company amortizes the capitalized commission cost as a selling expense on a straight-line basis over a period of five years.
The Company classifies deferred commissions as current or noncurrent based on the timing of when it expects to recognize the expense. The current and
noncurrent  portions  of  deferred  commissions  are  included  in  prepaid  expenses  and  other  current  assets  and  other  noncurrent  assets,  respectively,  in  its
consolidated balance sheets.

Advertising Expenses

Advertising  costs  are  expensed  as  incurred  and  are  included  in  sales  and  marketing  expense  in  the  consolidated  statements  of  operations.  The

Company incurred advertising costs of $3.0 million, $3.3 million and $2.1 million for the years ended December 31, 2023, 2022 and 2021, respectively.

Income Taxes

The Company provides for the effect of income taxes in its consolidated financial statements using the asset and liability method which requires the
recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the consolidated financial
statements.  Under  this  method,  deferred  tax  assets  and  liabilities  are  recognized  for  the  future  tax  consequences  attributable  to  differences  between  the
financial  statement  carrying  amounts  of  existing  assets  and  liabilities  and  their  respective  tax  bases,  net  operating  loss  carryovers,  and  tax  credit  carry
forwards. The Company regularly reviews its deferred tax assets for recoverability and establishes a valuation allowance if it is more likely than not that
some portion or all of the deferred tax assets will not be realized. To make this assessment, the Company takes into account predictions of the amount and
category  of  taxable  income  from  various  sources  and  all  available  positive  and  negative  evidence  about  these  possible  sources  of  taxable  income.  The
weight  given  to  the  potential  effect  of  negative  and  positive  evidence  is  commensurate  with  the  extent  to  which  the  strength  of  the  evidence  can  be
objectively verified. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those
temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the
period that includes the enactment date.

Income  tax  expense  or  benefit  is  recognized  for  the  amount  of  taxes  payable  or  refundable  for  the  current  year  and  for  deferred  tax  assets  and
liabilities  for  the  tax  consequences  of  events  that  have  been  recognized  in  an  entity’s  financial  statements  or  tax  returns.  The  Company  must  make
significant  assumptions,  judgments  and  estimates  to  determine  its  current  income  tax  provision  (benefit),  its  deferred  tax  assets  and  liabilities,  and  any
valuation allowance to be recorded against its deferred tax assets. The Company's estimates and assumptions may differ from the actual results as reflected
on its income tax returns and will record the required adjustments when they are identified or resolved.

The  Company  applies  a  two-step  approach  to  determining  the  financial  statement  recognition  and  measurement  of  uncertain  tax  positions.  The
Company only recognizes an income tax expense or benefit with respect to uncertain tax positions in its financial statements that the Company judges is
more likely than not to be sustained solely on its technical merits in a tax audit, including resolution of any related appeals or litigation processes. To make
this judgment, the Company must interpret complex and sometimes ambiguous tax laws, regulations and administrative practices. If an income tax position
meets the more likely than not recognition threshold, then the Company must measure the amount of the tax benefit to be recognized by determining the
largest  amount  of  tax  benefit  that  has  a  greater  than  a  50%  likelihood  of  being  realized  upon  effective  settlement  with  a  taxing  authority  that  has  full
knowledge  of  all  of  the  relevant  facts.  It  is  inherently  difficult  and  subjective  to  estimate  such  amounts,  as  this  requires  the  Company  to  determine  the
probability of various possible settlement outcomes. To determine if a tax position is effectively settled after a tax examination has been completed, the
Company must also estimate the likelihood that another taxing authority could review the respective tax position. The Company must also determine when
it is reasonably possible that the amount of unrecognized tax benefits will significantly increase or decrease in the 12 months after each fiscal year-end.
These judgments are difficult because a taxing authority may change its behavior as a result of the Company's disclosures in its financial statements. The
Company must reevaluate its income tax positions on a quarterly basis to consider factors such as changes in facts or circumstances, changes in tax law,
effectively settled issues under audit, and new audit activity. Such a change in recognition or measurement would result in recognition of a tax benefit or an
additional charge to the tax provision. The Company's policy is to recognize interest and penalties related to unrecognized tax benefits as a component of
the provision for income taxes.

Comprehensive Income (Loss)

Other comprehensive income (loss) consists of unrealized gains (losses) on marketable securities, net of tax, and derivative financial instruments
designated as cash flow hedges, net of tax, which are not included in the Company’s net income. Total comprehensive income includes net income and
other comprehensive income (loss) and is included in the consolidated statements of comprehensive income.

Foreign Currency Transactions

The Company’s operations are conducted in various countries around the world and the financial statements of its foreign subsidiaries are reported in
the U.S. dollar as their respective functional currency. Monetary assets and liabilities denominated in foreign currencies have been re-measured into U.S.
dollars using the exchange rates in effect at the balance sheet date, and income and expenses are re-measured at average exchange rates during the period.
Foreign currency re-measurement gains and losses and foreign currency transaction gains and losses are recognized in other income (expense), net.

Net Income Per Share

Basic net income per share is computed by dividing net income by the weighted-average number of shares outstanding during the period. Diluted net
income per share is computed by dividing net income by the weighted-average number of shares outstanding plus potentially dilutive shares outstanding
during the period. The potentially dilutive shares are computed by applying the treasury stock method to the Company's stock options, RSUs and the stock
purchase rights under the ESPP. Any potential shares that would be anti-dilutive are excluded from the computation of diluted net income per share.

Recently Adopted Accounting Pronouncements

None.

Recently Issued Accounting Pronouncements Not Yet Adopted

In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-07 requiring enhanced
segment disclosures. The ASU requires disclosure of significant segment expenses regularly provided to the chief operating decision maker ("CODM")
included within segment operating profit or loss. Additionally, the ASU requires a description of how the CODM utilizes segment operating profit or loss
to  assess  segment  performance.  The  requirements  of  the  ASU  are  effective  for  annual  periods  beginning  after  December  15,  2023,  and  interim  periods
within fiscal years beginning after December 15, 2024. The Company's annual reporting requirements will be effective for fiscal 2024 and interim reporting
requirements will be effective beginning with the first quarter of fiscal 2025. Early adoption is permitted and retrospective application is required for all
periods presented. The Company is in the process of analyzing the impact of the ASU on related disclosures.

In December 2023, the FASB issued ASU 2023-09 requiring enhanced income tax disclosures. The ASU requires disclosure of specific categories
and disaggregation of information in the rate reconciliation table. The ASU also requires disclosure of disaggregated information related to income taxes
paid, income or loss from continuing operations before income tax expense or benefit, and income tax expense or benefit from continuing operations. The
requirements of the ASU are effective for annual periods beginning after December 15, 2024. Early adoption is permitted and the amendments should be
applied  on  a  prospective  basis.  Retrospective  application  is  permitted.  The  Company  is  in  the  process  of  analyzing  the  impact  of  the  ASU  on  related
disclosures.

The Company does not believe any other new accounting pronouncements issued by the FASB that have not become effective will have a material

impact on its consolidated financial statements.

NOTE 2.     Fair Value of Financial Instruments

Fair  value  is  defined  as  the  price  that  would  be  received  to  sell  an  asset  or  paid  to  transfer  a  liability  in  an  orderly  transaction  between  market
participants at the measurement date. For certain of the Company’s financial instruments, including certain cash equivalents, accounts receivable, accounts
payable and accrued liabilities, the carrying amounts approximate their fair values due to the relatively short maturity of these balances.

67

Table of Contents

The Company measures and reports certain cash equivalents, marketable securities, derivative foreign currency forward contracts at fair value in
accordance with the provisions of the authoritative accounting guidance that addresses fair value measurements. This guidance establishes a hierarchy for
inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most
observable inputs be used when available. The hierarchy is broken down into three levels based on the reliability of inputs as follows:

Level 1 - Valuations based on quoted prices in active markets for identical assets or liabilities.

Level 2 - Valuations based on other than quoted prices in active markets for identical assets and liabilities, including quoted prices for identical assets
or liabilities in less active or inactive markets, quoted prices for similar assets or liabilities in active markets, or inputs other than quoted prices that are
observable for substantially the full term of the assets or liabilities.

Level  3  -  Valuations  based  on  inputs  that  are  generally  unobservable  and  typically  reflect  management’s  estimates  of  assumptions  that  market

participants would use in pricing the asset or liability.

The Company's financial instruments consist of assets and liabilities measured using Level 1 and 2 inputs. Level 1 assets include a highly liquid
money market fund, which is valued using unadjusted quoted prices that are available in an active market for an identical asset. Level 2 assets include
fixed-income U.S. Treasury and government agency securities, commercial paper, corporate bonds, asset-backed securities, foreign government securities
and derivative financial instruments consisting of foreign currency forward contracts. The securities, bonds and commercial paper are valued using prices
from independent pricing services based on quoted prices of identical instruments in less active or inactive markets, quoted prices of similar instruments in
active markets, or industry models using data inputs such as interest rates and prices that can be directly observed or corroborated in active markets. The
foreign currency forward contracts are valued using observable inputs, such as quotations on forward foreign exchange points and foreign interest rates.

The following table sets forth by level within the fair value hierarchy the fair value of the Company's financial assets and liabilities measured at fair

value on a recurring basis:

The  Company  considered  the  extent  to  which  any  unrealized  losses  on  its  marketable  securities  were  driven  by  credit  risk  and  other  factors,
including market risk, and if it is more-likely-than-not that the Company would have to sell the security before the recovery of the amortized cost basis. At
December  31,  2023  and  2022,  the  unrealized  losses  related  to  its  marketable  securities  were  due  to  rising  market  interest  rates  compared  to  when  the
investments were initiated. The Company does not believe the unrealized losses represent credit risk, and the Company does not intend to sell any of the
securities in an unrealized loss position and it is not likely that the Company would be required to sell these securities before recovery of their amortized
cost basis, which may be at maturity. Thus, no credit loss was recognized for the Company's marketable securities for the years ended December 31, 2023
and 2022.

The Company enters into foreign currency forward contracts to reduce the risk of variability in future cash flow due to foreign currency exchange
rate fluctuation from certain forecasted subscription revenue orders billed in GBP and EUR and operation expenses incurred in INR, which are designated
as cash flow hedges. Hedge effectiveness is assessed at inception and at each reporting period utilizing regression analysis. Unrealized foreign exchange
gains  or  losses  related  to  those  designated  cash  flow  hedge  contracts  are  recorded  in  accumulated  other  comprehensive  income  ("AOCI")  and  will  be
reclassified into revenues or operating expenses, respectively, in the same periods when the hedged transactions are recognized in earnings.

As of December 31, 2023, the Company had designated cash flow hedge forward contracts with notional amounts of €48.5 million, £14.6 million
and Rs.4,042.0 million. As of December 31, 2022, the Company had designated cash flow hedge forward contracts with notional amounts of €37.4 million,
£10.4 million and Rs.3,411.0 million.

Table of Contents

As of December 31, 2023, a net amount of unrealized loss of $1.5 million before tax on the foreign currency forward contracts for GBP and EUR
reported in AOCI is expected to be reclassified into revenue within the next 12 months. As of December 31, 2023, an immaterial amount of unrealized loss
before tax on the foreign currency forward contracts for INR reported in AOCI is expected to be reclassified into operating expenses within the next 12
months.

Non-designated forward contracts

The  Company  also  uses  foreign  currency  forward  contracts  to  hedge  certain  foreign  currency  denominated  assets  or  liabilities,  which  are  not
designated as cash flow hedges. Unrealized foreign exchange gain or losses related to the non-designated forward contracts are recorded in other income
(expenses), net and offset the foreign exchange gain or loss on the underlying net monetary assets or liabilities.

As  of  December  31,  2023,  the  Company  had  non-designated  forward  contracts  with  notional  amounts  of  €19.2  million,  £6.0  million,  Rs.440.0
million, and C$1.0 million. As of December 31, 2022, the Company had non-designated forward contracts with notional amounts of €40.2 million, £16.2
million, Rs.484.0 million, and C$3.8 million.

The  Company  presents  its  derivative  assets  and  derivative  liabilities  at  gross  fair  values  in  the  consolidated  balance  sheets.  However,  under  the
master netting agreements with the respective counterparties of the foreign exchange contracts, subject to applicable requirements, the Company is allowed
to net settle transactions of the same currency with a single net amount payable by one party to the other. The potential offset to both assets and liabilities

As of December 31, 2023 and 2022, physical scanner appliances and other computer equipment that are or will be subject to leases by customers had
a net carrying value of $10.1 million and $6.7 million, respectively, including assets that had not been placed in service of $6.4 million and $4.0 million,
respectively.

Depreciation and amortization expenses relating to property and equipment were $23.9 million, $28.2 million and $28.5 million for the years ended

December 31, 2023, 2022 and 2021, respectively, which were mainly recorded in cost of revenues in the consolidated statements of operations.

NOTE 5.     Revenue from Contracts with Customers

The  Company  records  deferred  revenue  when  cash  payments  are  received  or  due  in  advance  of  its  performance  obligations  offset  by  revenue
recognized in the period. Revenues of $292.2 million and $254.9 million were recognized during the years ended December 31, 2023 and December 31,
2022,  respectively,  which  amounts  were  included  in  the  deferred  revenue  balances  of  $317.2  million  and  $290.6  million  as  of  December  31,  2022  and
December 31, 2021, respectively

The  Company's  payment  terms  vary  by  the  type  and  location  of  its  customers.  The  term  between  invoicing  and  when  payment  is  due  is  not
significant.  In  certain  circumstances,  based  on  the  credit  quality  of  the  customer,  the  Company  requires  payment  before  the  products  or  services  are
delivered to the customer.

The following table sets forth the expected revenue from all remaining performance obligations as of December 31, 2023:

Revenues allocated to remaining performance obligations represents the transaction price of noncancelable orders for which service has not been
performed, which include deferred revenue and the amounts that will be invoiced and recognized as revenues in future periods from open contracts and
excludes unexercised renewals. The Company applied the short-term contract exemption to exclude the remaining performance obligations that are part of
a contract that has an original expected duration of one year or less.

From time to time, the Company enters into contracts with customers that extend beyond one year, with certain of its customers electing to pay for

more than one year of services upon contract execution. The Company concluded that these contracts did not contain a financing component.

The  Company  utilizes  partners  to  enable  and  accelerate  the  adoption  of  its  cloud  platform  by  increasing  its  distribution  capabilities  and  market
awareness  of  its  cloud  platform  as  well  as  by  targeting  geographic  regions  outside  the  reach  of  its  direct  sales  force.  The  Company's  channel  partners
maintain  relationships  with  their  customers  throughout  the  territories  in  which  they  operate  and  provide  their  customers  with  services  and  third-party
solutions to help meet those customers’ evolving security and compliance requirements. As such, these partners may offer the Company's IT security and
compliance solutions in conjunction with one or more of their own products or services and act as a conduit through which the Company can connect with
these prospective customers to offer its solutions. For sales involving a channel partner, the channel partner engages with the prospective customer directly
and involves the Company's sales team as needed to assist in developing and closing an order. When a channel partner secures a sale, the Company sells the
associated subscription to the channel partner who in turn resells the subscription to the customer. Sales to channel partners are made at a discount and
revenues are recorded at this discounted price over the subscription terms. The Company does not have any influence or specific knowledge of its partners'
selling terms with their customers. See Note 13, "Segment and Geographic Area Information" for disaggregation of revenue by geographic area.

NOTE 6.     Acquisitions

On  October  4,  2022,  the  Company  acquired  certain  assets  of  Blue  Hexagon  Inc.,  a  privately  held  company  incorporated  in  Delaware,  for  $10.0
million in cash, of which $8.5 million was paid on the acquisition date and the remaining $1.5 million will be due eighteen months from the acquisition
date, subject to potential adjustment from possible indemnity claims. In addition, the Company assumed $1.4 million deferred revenue. Blue Hexagon's
AI/ML-driven  network  detection  enables  the  Company  to  leverage  its  cloud  platform  with  AI/machine  learning  to  uncover  behavior  patterns  including
active vulnerability exploitation, identification of advanced network threats, and adaptive risk mitigation across all assets and application. The Company
accounted for this transaction as an asset acquisition, as substantially all of the fair value is concentrated in developed technology acquired. The Company
incurred $0.6 million transaction costs which is included as the cost of acquiring the intangible assets. The Company recognized intangible assets of $11.5
million for developed technology and $0.4 million for assembled workforce, which will be amortized over five years and two years, respectively.

On August 19, 2021, the Company acquired certain developed technology intangible assets of TotalCloud, a privately held company incorporated in

India, for a total cash consideration of $1.2 million, of which $1.1 million was paid on the acquisition

Table of Contents

date and the remaining $0.1 million was deferred and paid in August 2022. TotalCloud's technology strengthens the Company's cloud security solution by
allowing customers to build user-defined workflows for custom policies and execute them on-demand for simplified security and compliance. The acquired
intangible assets will be amortized over five years.

There were no changes in the carrying amount of goodwill for the years ended December 31, 2023 and 2022.

NOTE 7.     Intangible Assets, Net

NOTE 8.     Leases

The Company leases certain offices, computer equipment and its shared cloud platform facilities under non-cancelable operating leases for varying
periods through 2028. While under the Company's lease agreements the Company has options to extend its certain leases, the Company has not included
renewal  options  in  determining  the  lease  terms  for  calculating  its  lease  liabilities,  as  these  options  are  not  reasonably  certain  of  being  exercised.  Lease
expense was $16.1 million, $14.9 million and $16.8 million for the years ended December 31, 2023, 2022 and 2021, respectively.

NOTE 9.     Commitment and Contingencies

The  Company  has  entered  into  agreements  to  purchase  goods  and  services  in  the  ordinary  course  of  business.  As  of  December  31,  2023,  these

The Company from time to time enters into certain types of contracts that contingently require it to indemnify various parties against claims from
third  parties.  These  contracts  primarily  relate  to  (i)  the  Company's  bylaws,  under  which  it  must  indemnify  directors  and  executive  officers,  and  may
indemnify other officers and employees, for liabilities arising out of their relationship, (ii) contracts under which the Company must indemnify directors
and certain officers for liabilities arising out of their relationship, and (iii) contracts under which the Company may be required to indemnify customers or
resellers from certain liabilities arising from potential infringement of intellectual property rights, as well as potential damages caused by limited product
defects. To date, the Company has not incurred and has not recorded any liability in connection with such indemnifications.

The Company maintains director and officer insurance, which may cover certain liabilities arising from its obligation to indemnify its directors.

Legal Proceedings

From time to time the Company may become involved in legal proceedings or be subject to claims arising in the ordinary course of the Company's
business.  The  Company  records  a  provision  for  a  liability  when  it  is  both  probable  that  a  liability  has  been  incurred  and  the  amount  can  be  reasonably
estimated. Legal expenses related to such matters are expensed as incurred. The Company provides disclosure if it is reasonably possible that a loss has
been  incurred  and  a  range  of  loss  or  possible  loss  can  be  reasonably  estimated.  Significant  judgment  is  required  to  determine  both  probability  and  the
estimated amount. The Company reviews these provisions at least quarterly and adjust these provisions to reflect the impact of negotiations, settlements,
rulings, advice of legal counsel, and updated information.

As of December 31, 2023, there has not been at least a reasonable possibility that the Company has incurred a material loss from any ongoing legal
proceedings, individually or taken together. However, litigation is inherently unpredictable and is subject to significant uncertainties, some of which are
beyond the Company's control. Should any of these estimates and assumptions change or prove to have been incorrect, the Company could incur significant
charges related to legal matters which could have a material impact on its results of operations, financial position and cash flows.

NOTE 10.     Stockholders' Equity and Stock-based Compensation

Preferred Stock

Effective October 3, 2012, the Company is authorized to issue 20.0 million shares of undesignated preferred stock with a par value of $0.001 per
share. Each series of preferred stock will have such rights and preferences including dividend rights, dividend rate, conversion rights, voting rights, rights
and terms of redemption (including sinking fund provisions), redemption price, and liquidation preferences as determined by the board of directors. As of
December 31, 2023, and 2022, there were no issued or outstanding shares of preferred stock.

Equity Incentive Plan

2012 Equity Incentive Plan

The 2012 Equity Incentive Plan (“Previous 2012 Plan”) was adopted and approved in September 2012 and became effective on September 26, 2012.
Under  the  Previous  2012  Plan,  the  Company  is  authorized  to  grant  to  eligible  participant’s  incentive  stock  options  ("ISOs"),  nonstatutory  stock  options
("NSOs"),  stock  appreciation  rights  (“SARs”),  restricted  stock  awards,  restricted  stock  units  ("RSUs"),  performance  units  and  performance  shares.  The
number of shares of common stock available for issuance under the Previous 2012 Plan is subject to an annual increase on January 1 of each year by an
amount equal to the least of 3,050 thousand shares, 5% of the outstanding shares of stock as of the last day of the immediately preceding fiscal year or an
amount determined by the board of directors. For the year ended December 31, 2023, no shares were added to the Previous 2012 Plan.

On June 8, 2022 ("Effective Date"), the Company's stockholders approved the Amended and Restated 2012 Equity Incentive Plan (the "Restated
2012  Plan").  Under  the  Restated  2012  Plan,  the  Company  is  authorized  to  grant  to  eligible  participants  ISOs,  NSOs,  restricted  stock,  RSUs,  SARs,
performance units and performance shares. Pursuant to the relevant plan provisions, 3,072 thousand shares were available for grant under the Restated 2012
Plan on the Effective Date. In addition, any outstanding awards or options granted under the Previous 2012 Equity Incentive Plan will be added back to the
shares available for grant under the Restated 2012 Plan if they expire unexercised or are otherwise forfeited after the Effective Date. Any remaining shares
of 9,689 thousand available for grant under the Previous 2012 Plan as of the Effective Date were no longer available for future grants under the Restated
2012 Plan. As of December 31, 2023, 1,824 thousand shares are available for future grants. Options may be granted with an exercise price that is at least
equal to the fair market value of the Company's stock at the date of grant and are exercisable when vested. Options and RSU's granted generally vest over a
period  of  up  to  four  years.  ISOs  may  only  be  granted  to  employees  and  any  subsidiary  corporations'  employees.  All  other  awards  may  be  granted  to
employees, directors and consultants and subsidiary corporations' employees and consultants. Options, SARs, RSUs, performance units and performance
awards may be granted with vesting terms as determined by the board of directors and expire no more than ten years after the date of grant or earlier if
employment or service is terminated.

2021 Employee Stock Purchase Plan

On  June  9,  2021,  the  Company’s  stockholders  approved  the  2021  ESPP.  A  total  of  600  thousand  shares  were  authorized  for  issuance  to  eligible
participating employees upon adoption of the ESPP. The ESPP provides for consecutive 6-month offering periods beginning on or about August 16 and
February  16  of  each  year.  Eligible  employees  who  elect  to  participate  can  contribute  from  1%  to  15%  of  their  eligible  compensation  through  payroll
withholding.  During  any  offering  period,  contribution  rates  cannot  be  changed.  However,  eligible  employees  may  withdraw  from  the  current  offering
period. Any contributions made prior to each purchase date in the case of withdrawal or termination of employment will be refunded. On each purchase
date, eligible participating employees will purchase the shares at a price per share equal to 85% of the lesser of (i) the fair market value of the Company's
stock on the first trading day of the offering period or (ii) the fair market value of the Company's stock on the purchase date (i.e., the last trading day of the
offering period).

During  the  year  ended  December  31,  2023,  60  thousand  shares  were  issued  in  connection  with  the  purchase  of  common  stock  by  participating

employees. As of December 31, 2023, 494 thousand shares were available for future purchase.

Performance-Based Stock Options and Restricted Stock Units

On  December  21,  2018,  the  Compensation  and  Talent  committee  of  the  Company's  board  of  directors  (“Compensation  Committee”)  granted  the
equity award for 2019 to the Company’s former chief executive officer, Philippe Courtot (“Mr. Courtot”). The first portion of the award consisted of 56
thousand RSUs that were scheduled to vest in 16 quarterly increments beginning on January 1, 2019. The second portion of the award consisted of a target
number of 33 thousand PSUs, which were scheduled to vest at the end of the three-year performance period from January 2019 through December 2021.
The  actual  number  of  PSUs  eligible  to  vest  ranged  from  0%  to  200%  of  the  target  number,  depending  on  the  level  of  achievement  of  goals  related  to
revenue growth during the three-year performance period from January 2019 through December 2021 and Adjusted EBITDA margin for the fiscal year of
2021. The third portion of the award consisted of a target number of 33 thousand PSUs, one third of which (11 thousand target PSUs) was scheduled to vest
at the end of each fiscal year of 2019, 2020 and 2021. The actual number of PSUs eligible to vest at each vesting date ranged from 0% to 200% of the
target number, depending on the level of achievement of goals related to revenue growth and Adjusted EBITDA margin for each of those years.

On November 2, 2019, the Compensation Committee granted the equity award for 2020 to Mr. Courtot. The first portion of the award consisted of
49 thousand RSUs that were scheduled to vest in 16 quarterly installments beginning on December 1, 2019. The second portion of the award consisted of a
target number of 124 thousand PSOs, which were scheduled to vest at the end of the three-year performance period from January 2020 through December
2022. The actual number of PSOs eligible to vest ranged from 0% to 200% of the target number, depending on the level of achievement of goals related to
revenue growth and free cash flow per share growth during the performance period.

On December 10, 2020, the Compensation Committee granted the equity award for 2021 to Mr. Courtot. The first portion of the award consisted of
69 thousand RSUs that were scheduled to vest in 16 quarterly installments beginning on November 1, 2020. The second portion of the award consisted of a
target number of 224 thousand PSOs, which were scheduled to vest at the end of the three-year performance period from January 2021 through December
2023. The actual number of PSOs eligible to vest ranged from 0% to 200% of the target number, depending on the level of achievement of goals related to
revenue growth and free cash flow per share growth during the performance period.

The vesting of the above awards was conditioned on Mr. Courtot’s continued service through the vesting dates or, for PSOs and PSUs, the dates that
performance  is  certified  in  addition  to  the  achievement  of  performance  goals.  If  Mr.  Courtot’s  employment  was  terminated  (a)  by  reason  of  death  or
disability or (b) by the Company for reasons other than cause or good reason within 12 months following a change in control, then 100% of any unvested
portions of these awards would vest, with any vesting in connection with change in control terminations conditioned upon the effectiveness of a release of
claims in favor of the Company.

In  February  2021  and  2020,  22  thousand  shares  (representing  200%  of  target  number  of  awards)  and  15  thousand  shares  (representing  135%  of
target  number  of  awards)  under  the  equity  award  for  2019  for  Mr.  Courtot,  vested  as  a  result  of  the  Company  achieving  the  corresponding  level  of
performance goals for 2020 and 2019, respectively.

On  March  19,  2021,  Mr.  Courtot  resigned  from  the  Company  due  to  health  issues.  The  Compensation  Committee  determined  that  Mr.  Courtot’s
termination of employment was on account of disability. In accordance with the grant agreements of the equity awards for 2021, 2020 and 2019 for Mr.
Courtot, all remaining outstanding RSUs, PSUs and PSOs under these grants were subject to accelerated vesting and became fully vested at 100% of the
target number of awards as of the date of his termination of employment, which consist of 127 thousand RSUs, 44 thousand PSUs and 348 thousand PSOs.
As a result, the Company recognized an additional $27.3 million of stock-based compensation expense due to the accelerated vesting in the consolidated
statements of operations for the year ended December 31, 2021.

On April 27, 2021, the Compensation Committee granted to the Company’s current president and chief executive officer an equity award consisting
of certain RSUs and a target number of 10 thousand PSUs. The PSUs are scheduled to vest at the end of the three-year performance period from January
2021 through December 2023. The actual number of the PSUs eligible to vest range from 0% to 200% of the target number, depending on the level of
achievement of goals related to revenue growth and free cash flow per share growth during the performance period. If the Company's current president and
chief  executive  officer  is  terminated  (a)  by  reason  of  death  or  disability  or  (b)  by  the  Company  for  reasons  other  than  cause  or  good  reason  within  12
months following a change in control, then 100% of any unvested portions of the award will vest, with any vesting in connection with terminations due to
change in control conditioned upon the effectiveness of a release of claims in favor of the Company.

On October 28, 2021, the Compensation Committee approved to certain executive officers of the Company equity awards consisting of certain RSUs
and an aggregate target number of 73 thousand PSUs. The target PSUs are scheduled to vest in three equal annual installments over a three-year period
from  January  2022  through  December  2024.  Each  annual  installments  at  200%  of  the  annual  target  will  be  considered  granted  when  the  performance
targets for the corresponding performance year are determined and approved. The actual number of the PSUs eligible to vest each year range from 0% to
200% of the annual target number, depending on the level of achievement of goals related to revenue growth and adjusted EBITDA margin corresponding
to that year. The vesting and release of the first and second installment is capped at 100% of the target number at the end of the first and second year,
respectively, with cumulative achievement over 100%, if any, to be vested and released at the end of the third year, together with the vesting of the third
installment.

On October 27, 2022, the Compensation Committee approved to certain executive officers of the Company equity awards consisting of certain RSUs
and an aggregate target number of 86 thousand PSUs. The target PSUs are scheduled to vest in three equal annual installments over a three-year period
from  January  2023  through  December  2025.  Each  annual  installments  at  200%  of  the  annual  target  will  be  considered  granted  when  the  performance
targets for the corresponding performance year is determined and approved. The actual number of the PSUs eligible to vest each year range from 0% to

The realization of deferred tax assets is dependent upon the generation of sufficient taxable income of the appropriate character in future periods.
The Company regularly assesses the ability to realize its deferred tax assets and establishes a valuation allowance if it is more-likely than-not that some
portion,  or  all,  of  the  deferred  tax  assets  will  not  be  realized.  The  Company  weighs  all  available  positive  and  negative  evidence,  including  its  earnings
history and results of recent operations, scheduled reversals of deferred tax liabilities, projected future taxable income, and tax planning strategies. Due to
the  weight  of  objectively  verifiable  negative  evidence,  it  is  more-likely-than-not  that  its  California  deferred  tax  assets  will  not  be  realized  as  of
December 31, 2023. Additionally, due to a lack of sufficient future income of the appropriate character, certain U.S. federal and state deferred tax assets are
not  more-likely-than-not  to  be  realized.  Accordingly,  the  Company  has  recorded  a  valuation  allowance  of  $12.4  million  and  $12.5  million  against  such
deferred  tax  assets  as  of  December  31,  2023  and  2022,  respectively.  The  decrease  in  valuation  allowance  was  mainly  associated  with  the  California
research and development credit generated during the year ended December 31, 2023 offset by a decrease in unrealized loss on available for sale securities
that will not likely be realized in the foreseeable future.

As of December 31, 2023 and 2022, the Company had $17.0 million and $16.2 million, respectively, of California research and development credit
carryforwards. California research and development credits are carried forward indefinitely. As of December 31, 2023 and 2022, the Company had foreign
tax credit carryforwards of $1.0 million and $0.9 million, respectively, which begin to expire in 2028.

The  unrecognized  tax  benefits,  if  recognized,  would  impact  the  income  tax  provision  by  $6.1  million,  $5.3  million  and  $4.9  million  as  of
December 31, 2023, 2022 and 2021, respectively. The remaining amount would result in the recognition of a corresponding deferred tax asset that is then
offset by a full valuation allowance. As of December 31, 2023, the Company does not believe that its estimates, as otherwise provided for, on such tax
positions will significantly increase or decrease within the next twelve months. The Company has elected to include interest and penalties as a component
of income tax expense. The amounts were not material for the years ended December 31, 2023, 2022 and 2021.

The Company files income tax returns in the United States, including various state jurisdictions. The Company’s subsidiaries file tax returns in India
and  various  other  foreign  jurisdictions.  The  tax  years  2001  through  2023  remain  open  to  examination  by  the  major  taxing  jurisdictions  in  which  the
Company is subject to tax. The Company is also currently subject to tax audits in various jurisdictions. The Company believes that an adequate provision
has been made for any adjustments that may result from tax examinations. However, the outcome of tax audits cannot be predicted with certainty. If any
issues  addressed  in  the  Company's  tax  audits  are  resolved  in  a  manner  inconsistent  with  its  expectations,  the  Company  could  be  required  to  adjust  its
income tax provision in the period such resolution occurs.

As of  December  31,  2023,  the  Company  has  undistributed  earnings  in  certain  foreign  subsidiaries  that  the  Company  has  indefinitely  reinvested
outside the United States. Due to U.S. tax rules related to taxation of foreign earnings, the unrecorded deferred tax liability is immaterial. The Company
may be required to pay additional foreign withholding taxes if the Company repatriates those earnings in the future.

Item 9.    Changes In and Disagreements with Accountants on Accounting and Financial Disclosure

None.

Item 9A.    Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure
controls and procedures as of December 31, 2023. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the
Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the
reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Securities
and Exchange Commission’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure
that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to
the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required
disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of
achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.
Based  on  the  evaluation  of  our  disclosure  controls  and  procedures  as  of  December  31,  2023,  our  Chief  Executive  Officer  and  Chief  Financial  Officer
concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Management's Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules
13a-15(f) and 15d-15(f) of the Exchange Act. Our internal control over financial reporting is a process designed to provide reasonable assurance regarding
the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. GAAP. Our internal control
over financial reporting includes those policies and procedures that: (i) pertain to the maintenance of records that in reasonable detail accurately and fairly
reflect the transactions and dispositions of our assets, (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of
financial statements in accordance with U.S. GAAP, and that our receipts and expenditures are being made only in accordance with authorizations of our
management and directors, and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition
of our assets that could have a material effect on our financial statements.

Because  of  its  inherent  limitations,  internal  control  over  financial  reporting  may  not  prevent  or  detect  misstatements.  Also,  projections  of  any
evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree
of compliance with the policies or procedures may deteriorate.

Under  the  supervision  and  with  the  participation  of  our  management,  including  our  Chief  Executive  Officer  and  Chief  Financial  Officer,  we
conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2023 based on the criteria established in the
2013 Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission, or COSO. Based on our
evaluation under the criteria set forth in the 2013 Internal Control - Integrated Framework issued by the COSO, our management concluded our internal
control over financial reporting was effective as of December 31, 2023.

The effectiveness of the Company's internal control over financial reporting as of December 31, 2023 has been audited by Grant Thornton LLP, an

independent registered public accounting firm, as stated in its report, which is included in Item 8 of this Annual Report on Form 10-K.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and
15d-15(d) of the Exchange Act that occurred during the fourth quarter ended December 31, 2023 that has materially affected, or is reasonably likely to
materially affect, our internal control over financial reporting.

Item 9B.    Other Information

Securities Trading Plans of Directors and Executive Officers

During the three months ended December 31, 2023, the following director, as defined in Rule 16a-1(f), adopted a “Rule 10b5-1 trading arrangement”

as defined in Regulation S-K Item 408, as follows:

On November 21, 2023, Jeffrey P. Hank, the chair of our board of directors, adopted a Rule 10b5-1 trading arrangement providing for the sale from
time to time of an aggregate of up to 8,850 shares of our common stock plus an additional number of shares to be granted on the date of the Company's
2024  Annual  Meeting  of  Stockholders.  Pursuant  to  the  Company's  non-employee  director  compensation  program,  each  non-employee  director  who  has
served on our board of directors for at least six months prior to such date will be granted an award of restricted stock units with an intended value (based on
the average of the closing prices of our common stock for the 30 trading days ending one week before the applicable grant date) of $200,000.

The trading arrangement is intended to satisfy the affirmative defense in Rule 10b5-1(c). The duration of the trading arrangement is until June 30,

2025, or earlier if all transactions under the trading arrangement are completed.

No other director or officer, as defined in Rule 16a-1(f), adopted or terminated a “Rule 10b5-1 trading arrangement” or a “non-Rule 10b5-1 trading

arrangement,” each as defined in Regulation S-K Item 408, during the three months ended December 31, 2023.

Exhibit 10.10

1. Purpose. The purpose of this 2023 Corporate Bonus Plan (the “Plan”) is to motivate and encourage the employees of Qualys (the “Company”)

to achieve its stated goals and to assist the Company in attracting, motivating and retaining employees on a competitive basis.

2023 CORPORATE BONUS PLAN

2. Eligibility

(a) An officer or employee of the Company is designated as a participant in the Plan ("Participant") and shall be eligible to participate in the Plan

if they are either a regular full-time or regular part-time employee (working greater than 20 hours a week) and they are not already participating in a
separate Compensation or MBO plan.

(b) New Hires. New employees hired in the first or second month of a quarter will be eligible to participate in the Plan for that quarter, such

participation will be prorated based on the number of working days employed in the quarter.

(c) Termination of Employment. To be eligible for the bonus, the employee must be employed as of the last working day of the quarter.

(d) Absence during Performance Period. If a Participant is absent for a period of more than one-half of the working days in a quarter, for any

reason, the Participant’s bonus payment will be prorated based on the number of working days the Participant actually worked compared to the total
number of working days during that quarter.

3. Bonus Criteria

(a) Bonus Period. The Bonus Plan is effective from January 1, 2023 through December 31, 2023. Each calendar quarter is a separate bonus

period.

(b) Bonus Level. A Participant’s level of participation in the Plan is set based on the corporate bonus level as of the last working day of that

quarter as well as their location and applicable variable plan during the Bonus Period as determined by the Human Resources Department. This will be
applied to the Participant’s base salary to determine the bonus amount.

Effective 1/1/2023

(c) Objective Criteria: The Plan payments will be based on ASV (as defined below), Revenue (as defined below) and Non-GAAP EPS (as

defined below).

(1) ASV. The stated goal is the growth in company-wide bookings as represented by Annual Subscription Value (“ASV”) for the current

quarter over the same quarter of the prior year. ASV is the sum of one year’s worth of subscribed revenues to Qualys for all new, renewal and
upsell subscriptions contracted by customers and channel partners in each quarter. ASV is determined by policies and practices administered by
the Controller and the final quarterly ASV amount is approved by the CFO.

(2) Revenue. The stated goal is the growth in company-wide revenue (as determined in accordance with GAAP and set forth in the

Company’s quarterly and annual financial statements) for the current quarter over the same quarter of the prior year.

(3) Non-GAAP EPS. The stated goal is Non-GAAP earnings per diluted share. Non-GAAP EPS is GAAP net income less stock-based
compensation expense, acquisition-related expenses (except for ordinary course advisory fees), tax adjustments and bonus payments under this
Plan divided by weighted average shares (diluted) for the applicable quarter.

(d) Payout Calculation. A Participant’s bonus amount will be equal to the aggregate for each of the applicable objective goals as follows: the

payment percentage described below multiplied by weighting percentage for the applicable goal. ASV Growth, Revenue Growth and Non-GAAP EPS shall
be the 3 goals and shall be equally weighted.

(1) ASV. The payout percentage scales based upon achievement of ASV as described in Section 1 of the Appendix [***].

(2) Revenue. The payout percentage scales based upon achievement of Revenue as described in Section 2 of the Appendix [***].

(3) Non-GAAP EPS. The payout percentage scales based upon achievement of Non-GAAP EPS as described in Section 3 of the

Appendix [***].

(e) Bonus Payments. Bonus payments to Participants under this Plan will be made with the first payroll of the second month following the end of

the quarter. Bonus payments are “gross” amounts, meaning that they constitute the full amount and that there will be no other increases (for example, to
cover income taxes). The company will deduct from any payment under the Plan the amount of all applicable income and employment taxes, and any other
amounts required by law to be withheld or deducted from such payment, and any voluntary deductions applicable. None of the payments will be “benefits
bearing” (i.e., the bonus amounts will not be used for purposes of determining any other company-provided benefits or compensation).

Administration. This Plan shall be administered by the Company’s CFO (except with respect to Participants who are the Company’s executive officers, in
which case the Compensation and Talent Committee of the Board of Directors will serve as the administrator), who may make and apply such rules deemed
desirable or necessary to administer the Plan in the best interests of the Company. All questions of interpretation or application of the Plan may be
addressed in writing to the CFO (or as applicable, the Compensation and Talent Committee), who shall review each inquiry in good faith, and each such
determination shall be final and binding. With the approval of the Compensation and Talent Committee, the results with respect to determination of ASV,
Revenue, and Non-GAAP EPS will be adjusted to remove the effects of charges for restructurings, discontinued operations, extraordinary items and all
items of gain, loss or expense determined to be extraordinary or unusual in nature or related to the disposal of a segment of a business or related to a change
in accounting principle, asset write-downs, litigation, claims, judgments or settlements, the effect of changes in tax law or other such laws or provisions
affecting reported results, accruals for reorganization and restructuring programs.

I have reviewed this annual report on Form 10-K of Qualys, Inc.;

Based on my knowledge, this report does not contain any untrue statement of a material fact or omit to state a material fact necessary to make the

Based on my knowledge, the financial statements, and other financial information included in this report, fairly present in all material respects the

The  registrant’s  other  certifying  officer  and  I  are  responsible  for  establishing  and  maintaining  disclosure  controls  and  procedures  (as  defined  in

QUALYS, INC.

COMPENSATION RECOVERY POLICY

As adopted on October 26, 2023

Exhibit 97.1

Qualys, Inc. (the “Company”) is committed to strong corporate governance. As part of this commitment, the Company’s Board of Directors (the
“Board”) has adopted this clawback policy called the Compensation Recovery Policy (the “Policy”). The Policy is intended to further the Company’s pay-
for-performance  philosophy  and  to  comply  with  applicable  laws  by  providing  rules  relating  to  the  reasonably  prompt  recovery  of  certain  compensation
received  by  Covered  Executives  in  the  event  of  an  Accounting  Restatement.  The  application  of  the  Policy  to  Covered  Executives  is  not  discretionary,
except to the limited extent provided below, and applies without regard to whether a Covered Executive was at fault. Capitalized terms used in the Policy
are defined below, and the definitions have substantive impact on its application so reviewing them carefully is important to your understanding.

The Policy is intended to comply with, and will be interpreted in a manner consistent with, Section 10D of the Securities Exchange Act of 1934
(the “Exchange Act”), with Exchange Act Rule 10D-1 and with the listing standards of the national securities exchange (the “Exchange”) on which the
securities of the Company are listed, including any official interpretive guidance.

Persons Covered by the Policy

The Policy is binding and enforceable against all “Covered Executives.” A Covered Executive is each individual who is or was ever designated
as an “officer” by the Board in accordance with Exchange Act Rule 16a-1(f) (a “Section 16 Officer”). The Committee may (but is not obligated to) request
or  require  a  Covered  Executive  to  sign  and  return  to  the  Company  an  acknowledgement  that  such  Covered  Executive  will  be  bound  by  the  terms  and
comply with the Policy. The Policy is binding on each Covered Executive whether or not the Covered Executive signs and/or returns any acknowledgment.

Administration of the Policy

The Compensation and Talent Committee (the “Committee”) of the Board has full delegated authority to administer the Policy. The Committee is
authorized to interpret and construe the Policy and to make all determinations necessary, appropriate, or advisable for the administration of the Policy. In
addition, if determined in the discretion of the Board, the Policy may be administered by the independent members of the Board or another committee of
the  Board  made  up  of  independent  members  of  the  Board,  in  which  case  all  references  to  the  Committee  will  be  deemed  to  refer  to  the  independent
members  of  the  Board  or  the  other  Board  committee.  All  determinations  of  the  Committee  will  be  final  and  binding  and  will  be  given  the  maximum
deference permitted by law.

Accounting Restatements Requiring Application of the Policy

If the Company is required to prepare an accounting restatement due to the material noncompliance of the Company with any financial reporting
requirement under the securities laws, including any required accounting restatement to correct an error in previously issued financial statements that is
material to the previously issued financial statements, or that would result in a material misstatement if the error were corrected in the current period or left
uncorrected  in  the  current  period  (an  “Accounting Restatement”),  then  the  Committee  must  determine  the  Excess  Compensation,  if  any,  that  must  be
recovered. The Company’s obligation to recover Excess Compensation is not dependent on if or when restated financial statements are filed.

Compensation Covered by the Policy

The Policy applies to certain Incentive-Based Compensation (certain terms used in this Section are defined below) that is Received on or after
October 2, 2023 (the “Effective Date”), during the Covered Period while the Company has a class of securities listed on a national securities exchange.
Such  Incentive-Based  Compensation  is  considered  “Clawback  Eligible  Incentive-Based  Compensation”  if  the  Incentive-Based  Compensation  is
Received by a person after such person became a Section 16 Officer and the person served as a Section 16 Officer at any time during the

performance  period  for  the  Incentive-Based  Compensation.  “Excess  Compensation”  means  the  amount  of  Clawback  Eligible  Incentive-Based
Compensation that exceeds the amount of Clawback Eligible Incentive-Based Compensation that otherwise would have been Received had such Clawback
Eligible Incentive-Based Compensation been determined based on the restated amounts. Excess Compensation must be computed without regard to any
taxes paid and is referred to in the listings standards as “erroneously awarded compensation”.

To determine the amount of Excess Compensation for Incentive-Based Compensation based on stock price or total shareholder return, where it is
not subject to mathematical recalculation directly from the information in an Accounting Restatement, the amount must be based on a reasonable estimate
of the effect of the Accounting Restatement on the stock price or total shareholder return upon which the Incentive-Based Compensation was Received and
the Company must maintain documentation of the determination of that reasonable estimate and provide that documentation to the Exchange.

“Incentive-Based Compensation” means any compensation that is granted, earned, or vested based wholly or in part upon the attainment of a
Financial Reporting Measure. For the avoidance of doubt, no compensation that is potentially subject to recovery under the Policy will be earned until the
Company’s right to recover under the Policy has lapsed.

“Financial Reporting Measures” are measures that are determined and presented in accordance with the accounting principles used in preparing
the Company’s financial statements, and any measures that are derived wholly or in part from such measures. Stock price and total shareholder return are
also Financial Reporting Measures. A Financial Reporting Measure need not be presented within the financial statements or included in a filing with the
Securities and Exchange Commission.

Incentive-Based  Compensation  is  “Received”  under  the  Policy  in  the  Company’s  fiscal  period  during  which  the  Financial  Reporting  Measure
specified in the Incentive-Based Compensation award is attained, even if the payment, vesting, settlement or grant of the Incentive-Based Compensation

occurs  after  the  end  of  that  period.  For  the  avoidance  of  doubt,  the  Policy  does  not  apply  to  Incentive-Based  Compensation  for  which  the  Financial
Reporting Measure is attained prior to the Effective Date.

“Covered Period” means the three completed fiscal years immediately preceding the Accounting Restatement Determination Date. In addition,

Covered Period can include certain transition periods resulting from a change in the Company’s fiscal year.

“Accounting Restatement Determination Date” means the earliest to occur of: (a) the date the Board, a committee of the Board, or one or more
of the officers of the Company authorized to take such action if Board action is not required, concludes, or reasonably should have concluded, that the
Company is required to prepare an Accounting Restatement; and (b) the date a court, regulator, or other legally authorized body directs the Company to
prepare an Accounting Restatement.

Repayment of Excess Compensation

The Company must recover Excess Compensation reasonably promptly and Covered Executives are required to repay Excess Compensation to the
Company. Subject to applicable law, the Company may recover Excess Compensation by requiring the Covered Executive to repay such amount to the
Company  by  direct  payment  to  the  Company  or  such  other  means  or  combination  of  means  as  the  Committee  determines  to  be  appropriate  (these
determinations do not need to be identical as to each Covered Executive). These means include (but are not limited to):

a.

requiring reimbursement of cash Incentive-Based Compensation previously paid;

b.

c.

d.

seeking  recovery  of  any  gain  realized  on  the  vesting,  exercise,  settlement,  sale,  transfer,  or  other  disposition  of  any  equity-based  awards
(including, but not limited to, time-based vesting awards), without regard to whether such awards are Incentive-Based Compensation or vest based
on the achievement of performance goals;

offsetting the amount to be recovered from any unpaid or future compensation to be paid by the Company or any affiliate of the Company to the
Covered Executive, including (but not limited to) payments of severance that might otherwise be due in connection with a Covered Executive’s
termination of employment and without regard to whether such amounts are Incentive-Based Compensation;

cancelling outstanding vested or unvested equity awards (including, but not limited to, time-based vesting awards), without regard to whether such
awards are Incentive-Based Compensation; and/or

e.

taking any other remedial and recovery action permitted by law, as determined by the Committee.

The repayment of Excess Compensation must be made by a Covered Executive notwithstanding any Covered Executive’s belief (whether or not

legitimate) that the Excess Compensation had been previously earned under applicable law and therefore is not subject to clawback.

In  addition  to  its  rights  to  recovery  under  the  Policy,  the  Company  or  any  affiliate  of  the  Company  may  take  any  legal  actions  it  determines
appropriate to enforce a Covered Executive’s obligations to the Company or to discipline a Covered Executive. Failure of a Covered Executive to comply
with  their  obligations  under  the  Policy  may  result  in  (without  limitation)  termination  of  that  Covered  Executive’s  employment,  institution  of  civil
proceedings,  reporting  of  misconduct  to  appropriate  governmental  authorities,  reduction  of  future  compensation  opportunities  or  change  in  role.  The
decision to take any actions described in the preceding sentence will not be subject to the approval of the Committee and can be made by the Board, any
committee  of  the  Board,  or  any  duly  authorized  officer  of  the  Company  or  of  any  applicable  affiliate  of  the  Company.  For  avoidance  of  doubt,  any
decisions of the Company or the Covered Executive’s employer to discipline a Covered Executive or terminate the employment of a Covered Executive are
independent of determinations under this Policy. For example, if a Covered Executive was involved in activities that led to an Accounting Restatement, the
Company’s decision as to whether to not to terminate such Covered Executive’s employment would be made under its employment arrangements with such
Covered  Executive  and  the  requirement  to  apply  this  no-fault  and  non-discretionary  clawback  policy  will  not  be  determinative  of  whether  any  such
termination is for cause, although failure to comply with the Policy might be something that could result in a termination for cause depending on the terms
of such arrangements.

Limited Exceptions to the Policy

The Company must recover the Excess Compensation in accordance with the Policy except to the limited extent that any of the conditions set

forth below is met, and the Committee determines that recovery of the Excess Compensation would be impracticable:

a. The  direct  expense  paid  to  a  third  party  to  assist  in  enforcing  the  Policy  would  exceed  the  amount  to  be  recovered.  Before  reaching  this
conclusion, the Company must make a reasonable attempt to recover such Excess Compensation, document such reasonable attempt(s) to recover,
and provide that documentation to the Exchange; or

b. Recovery would likely cause an otherwise tax-qualified retirement plan, under which benefits are broadly available to employees of the Company,

to fail to meet the legal requirements as such.

Other Important Information in the Policy

The  Policy  is  in  addition  to  the  requirements  of  Section  304  of  the  Sarbanes-Oxley  Act  of  2002  that  are  applicable  to  the  Company’s  Chief
Executive Officer and Chief Financial Officer, as well as any other applicable laws, regulatory requirements, rules, or pursuant to the terms of any existing
Company policy or agreement providing for the recovery of compensation.

Notwithstanding  the  terms  of  any  of  the  Company’s  organizational  documents  (including,  but  not  limited  to,  the  Company’s  bylaws),  any
corporate policy or any contract (including, but not limited to, any indemnification agreement), neither the Company nor any affiliate of the Company will
indemnify  or  provide  advancement  for  any  Covered  Executive  against  any  loss  of  Excess  Compensation.  Neither  the  Company  nor  any  affiliate  of  the
Company will pay for or reimburse insurance premiums for an insurance policy that covers potential recovery obligations. In the event that the Company is
required to recover Excess Compensation pursuant to the Policy from a Covered Executive who is no longer an employee, the Company will be entitled to
seek recovery in order to comply with applicable law, regardless of the terms of any release of claims or separation agreement that individual may have
signed.

The Committee or Board may review and modify the Policy from time to time.

If  any  provision  of  the  Policy  or  the  application  of  any  such  provision  to  any  Covered  Executive  is  adjudicated  to  be  invalid,  illegal  or

unenforceable in any respect, such invalidity, illegality or unenforceability will not affect any other

provisions  of  the  Policy  or  the  application  of  such  provision  to  another  Covered  Executive,  and  the  invalid,  illegal  or  unenforceable  provisions  will  be
deemed amended to the minimum extent necessary to render any such provision or application enforceable.

The Policy will terminate and no longer be enforceable when the Company ceases to be a listed issuer within the meaning of Section 10D of the

Exchange Act.
