vALUe-ADDeD OFFeriNG
1. An immediate solution at their fingertips

DCN were interested in an immediate solution: “Whereas other vendors were still talking about their 
roadmaps and what they would do in the future, Corero could do everything immediately, and didn’t 
need to talk about their roadmap,” said Heck. “We don’t want to see a roadmap, we want to see 
what you can do today, because we need this right away.”

Corero also supported DCN’s strategic goals for ROI on their DDoS protection investments, helping 
to meet their objectives to sell DDoS as a service to their downstream customers.

“ We’ll be introducing DDoS protection to a lot of our internet customers that don’t have it today.  

It’s  a base service that they all should have from just a good cybersecurity posture.” 
Jesse Heck, Sr. Director of Operations at Dakota Carrier Network

The team at DCN was clear with Corero at the outset, that they prefer to do business by finding 
partners, not vendors, and Corero have exemplified that they fit this model well.

2. Faster time to mitigation

Corero stood out from the competition because it was the only vendor to offer sample packet 
mirroring functionality, which allows DCN to ingest traffic with faster time to mitigation. This enables 
DCN to analyse the malicious traffic in real-time and take relevant action against it.

3. Excellent customer support

“Corero separated themselves from the pack early on, just by being responsive at every step along 
the way,” said Heck. “They had a team of people who could answer our questions immediately, so we 
never had to chase them down for information as we did some of the other vendors.”

Dakota Carrier Network 
improves Customer 
Security and drives 
rOi with Corero DDoS 
Protection

OVERVIEW:
Dakota Carrier Network (DCN) is 
a consortium of 13 independent 
broadband companies located 
in North Dakota. The consortium 
has a fiber footprint stemming 
60,000 miles in the state of 
North Dakota, and represents 
all the major local independent 
broadband service providers 
and serve customers in 379 
communities. This adds up 
to over 85 percent of all the 
exchanges in the state. DCN 

provides critical network services 
to state and local governments 
along with commercial 
businesses, including banks 
and energy companies.

CHALLENGE:
Like most other broadband 
service providers, DCN has been 
targeted by cyber attackers 
with frequent and sophisticated 
DDoS attacks designed to create 
service latency and downtime for 
its network and their customers. 
DCN needed a DDoS protection 

solution that works fast, is 
automated, and could protect at 
scale. Prior to evaluating Corero 
solutions, the organisation 
had a dual-vendor DDoS 
mitigation solution involving 
one vendor that analysed 
traffic to detect DDoS traffic, 
and another that provided the 
hardware scrubbing.

However this split-vendor 
solution was unable to provide 
the DDoS Protection service 
DCN required. In addition, DCN 
wanted a single-sourced, multi-
tenant portal to provide their 
customers with a dashboard 
to show their network traffic, 
enable them to apply or remove 
attack mitigation policies and 
manage reporting. 

SOLUTION:
DCN has a multi-edge, multi-
terabit detect and redirect DDoS 
protection solution that analyses 
traffic as it comes in, with sample 
packet mirror. Malicious or 
attack traffic is automatically 
sent using BGP protocols to the 
Corero Threat Defence System 
which acts as a scrubber to filter 
the attack traffic, with the clean 
traffic then being returned.

DCN is introducing DDoS 
protection as a service to their 
customer base. “Now that we 
have a solid DDoS mitigation 
product, with a single-source 
portal, we are introducing it 
to a lot of our customers that 
don’t have DDoS protection” 
said Heck, commenting that 
the process of adding their 
customers to the mitigation 
service was completely 
“seamless” with no disruption. 

RESULTS:

Many DDoS solutions are 
merely reactive and only start 
working once the DDoS attack 
has already hit its victim. With 
Corero’s SmartWall solution, 
DCN benefits from automatic 
protection using analytics to 
aggregate historical records 
of DDoS traffic. By detecting 
anomalous traffic at the 
network edge, attacks are 
mitigated before they can cause 
any harm to the network or 
downstream customers.

“

Thanks to the 
Corero solution, 
our customers 
can access the 
DDoS portal 
for history and 
details regarding 
mitigation events 
including source 
and destination 
iPs, source and 
destination TCP/
UDP ports, and 
attack volume.”

CYBER THREATS AND 
DDOS ATTACKS
A wide range of critical cybersecurity 
issues face every internet connected 
organisation. These threats include 
DDoS, hacking, breach, phishing, 
fraud, ransom, data theft and 
exfiltration. These cyber threats 
present themselves via the internet 
connections that are essential to 
support online business.

Traditionally, internet service providers 
sell raw internet transit connectivity. 
This unprotected connectivity, 
usually sold via 1Gbps, 10Gbps and 
increasingly 100Gbps links, carries 
good customer traffic and malicious 
bad traffic without discrimination. If 
an enterprise, data centre, or hosting 
facility connects to these raw transit 
providers they will be exposed to 
internet-borne cyber threats and their 
information security posture must be 
prepared to detect and protect against 
any associated malicious intent.

Corero focuses on one specific 
category of these cybersecurity 
threats known as Distributed Denial 
of Service (DDoS) and has developed 
an innovative, flexible, solution that 
delivers automatic detection and 
protection against these attacks. 

The broad range of motives for 
executing DDoS attacks, coupled with 
the relative ease with which they can 
be launched, means a variety of actors, 
including; criminal gangs, activists, 
terrorist groups and even nation states 
use them. Aside from those who are 
focused purely on disrupting services, 
some of those who carry out DDoS 
attacks do so for extortion, via ransom 
DDoS, or as a smokescreen for other 
cyberattacks designed to steal data.

DDoS attacks continue to grow in 
sophistication, scale and frequency.

Businesses and public-sector 
organisations are equally vulnerable 
to DDoS attacks and recent years have 
seen some of the world’s best-known 
companies fall victim to these attacks, 
with a significant impact for their 
customers and bottom line.

The DDoS protection market is driven 
by the growing need for business 
continuity. Increasingly, always-on 
protection is the only answer to defend 
against the short, sharp, attacks which 
dominate. This is driving an increasing 
value-add service revenue opportunity 
for service providers.

every half and full year, Corero looks at 
the latest trends in the DDoS market. The 
observations below are from our 2022 DDoS 
Threat intelligence report.

In 2022, we witnessed significant changes in the global 
DDoS attack landscape. Corero has detected a surge in the 
overall volume of attacks, as well as variations in their nature, 
with attackers employing increasingly frequent, potent, and 
intricate tactics.

DDoS attacks aim to incapacitate online services by inundating 
them with traffic from multiple sources, typically through botnets 
and other means, to surpass the available bandwidth and 
paralyse the internet traffic flow. These attacks target service and 
network availability, negatively impacting business continuity and 
uptime, leading to downtime, internet disruption, loss of revenue, 
customer loyalty, and brand trust.

While traditional DDoS attacks typically deploy fewer packets 
of larger sizes, our observations indicate that recent attacks 
are employing larger numbers of smaller-sized packets, 
aiming to overwhelm a target’s transactional processing. This 
highlights the criticality of robust DDoS protection for the 
service and hosting providers responsible for maintaining 
customers’ internet availability. 

One of the most significant developments in DDoS attacks 
in 2022 was the rise of ‘carpet bomb’ attacks, posing a 
significant threat. These circumvent legacy detect-and-redirect 
DDoS protection systems by launching multiple small attacks. 
You can learn more about these emerging DDoS threats in 
the report which can be downloaded from www.corero.com/
about/newsroom.

In conclusion, our key takeaway is that awareness and 
protocols alone are insufficient countermeasures against 
today’s DDoS threat. Fast-acting, real-time automatic 
detection and mitigation continues to be the best line 
of defence against these attacks.

• 

IoT devices, which are the source of high-intensity 
DDoS attacks, forecast to grow 18% to 14.4 billion 
during 2023.2

•  The increased bandwidth of 5G networks opens 

avenues for DDoS attackers to induce large DDoS 
attacks leveraging millions of mobile or IoT devices.1

•  Communication service providers (‘CSPs’) are 

increasingly targets, with limited capability to defend 
against any such attacks. The increase in IoT devices due 
to the growth of 5G further increases the risk to CSPs.

wHAT iS OUr MiSSiON? 
To be the customer’s trusted partner on their journey to implement effective DDoS 
protection matched to their needs. 

WHAT IS A DDOS ATTACK? 
A DDoS attack is a cyber threat, in which 
multiple computer systems or devices 
attack a target, such as a server, website 
or network, and impact the users of the 
targeted resources. 

The flood of incoming messages, connection 
requests, or malformed packets sent to the 
target causes it to slow or shut down or 
congests the host network thereby denying 
service to legitimate users. 

DDoS attacks are a threat to service 
availability, network security, brand reputation 
and ultimately lead to lost revenues.

Attackers are continuing to leverage DDoS 
attacks as part of their cyber threat arsenal 
to either disrupt business operations or 
provide a smokescreen while they attempt 
to access sensitive corporate information. 

Attackers are increasingly leveraging creative 
ways to circumvent traditional security 
solutions or reduce the effectiveness of 
DDoS scrubbing solutions. DDoS attacks 
can be found in a multitude of sizes and 
are launched for a variety of motivations. 
They may also be used to extort payments 
via Ransom DDoS. Today’s cyber criminals 
do not even have to construct the attacks 
themselves. They can simply download 
ready made DDoS tools or use DDoS for 
hire services on the darkweb to accomplish 
their goals.

STEPS IN A TYPICAL DDOS 
BOTNET ATTACK
Step 1
Botmaster sends command and control 
signals to a botnet of infected devices or 
hosts identifying victim and desired type  
of attack.

Step 2
Botnet receives instruction and begins 
to attack designated victim by sending a 
variety of malicious DDoS traffic across  
the internet.

Step 3
Traffic from attacking bots, distributed across 
the internet, converges on the victim at the 
same time resulting in congestion, overload 
and denial of service for legitimate users.

WHAT DAMAGE CAN A DDOS 
ATTACK DO? 
High availability of Cloud services and online 
applications are critical for modern businesses 
and institutions. Any downtime brings risk, 
including: 

• 

• 

Lost revenue.

Loss of control.

•  Operational costs to mitigate or recover 

from attacks. 

• 

Increased costs to retain unhappy 
customers and attract new customers. 

•  Brand and reputation damage leading 
to competitive disadvantage or loss of 
confidence. 

•  Regulatory fines, legal action, 

resignations.

largest provider networks. Corero’s edge 
solution includes integration that directly 
powers the silicon filtering capabilities 
increasingly built into modern edge 
routers, scaling to tens-of-terabits per 
second of protection, without the need to 
deploy additional appliances at the edge 
or needing to back-haul large volumes of 
attack traffic to scrubbing centres.

WHAT CUSTOMER PROFILES 
DO WE TARGET?
Corero’s Ideal Customer Profile (‘ICP’) is 
broken down into 3 distinct groups. The 
first being Tier 2 or Tier 3 internet service 
providers whose commercial customers 
would be potential customers for a DDoS 
Protection Service. The second group 
consists of hosting and cloud providers that 
provide critical services and infrastructure 
to business customers. The third group 
comprises SaaS providers that have their own 
infrastructure which requires protection to 
ensure service availability for their customers.

WHAT STRATEGIC ALLIANCES 
DO WE HAVE?
Juniper Networks
Juniper Networks, Inc. (NYSE: JNPR) 
(‘Juniper’) is one of the world’s largest 
networking product, solutions and services 
companies, with revenues of over $5.3bn 
in 2022. Corero has a global partnership 
agreement with Juniper enabling Juniper 
to sell Corero’s SmartWall Threat Defence 
Director (‘TDD’) software product in 
conjunction with its own MX and PTX Series 
routers. Juniper and Corero have developed 
this fully integrated solution for large-scale 
network-edge DDoS defence that leverages 
powerful filtering capabilities in the latest 
generation of Juniper’s MX and PTX  
Series routers.

GTT Communications
GTT Communications, Inc. (NYSE: GTT) 
(‘GTT’) is a leading global cloud networking 
provider to multinational clients, with 
over 600 points of presence (‘POPs’), with 
revenues of $1.7bn in 2022. GTT operates a 
global Tier 1 internet network and provides 
a comprehensive suite of cloud networking 
services. GTT customers can purchase IP 
transit with DDoS protection powered by 
Corero’s SmartWall Solutions which are 
deployed in the GTT network. 

Neustar
Neustar, Inc. (‘Neustar’), through Neustar 
Security Services, is an American 
technology company that provides real-time 
information and analytics for the Internet, 
risk, digital performance and defence, 
telecommunications, entertainment, and 

marketing industries, and also provides 
clearinghouse and directory services to 
the global communications and Internet 
industries. Corero’s hybrid DDoS protection 
solution combines the Corero on-premises 
SmartWall TDS with the SmartWall Threat 
Defence Cloud (‘TDC’) service, powered by 
Neustar, which provides protection against 
the largest attacks which can saturate an 
organisation’s internet connections and 
overwhelm legitimate traffic.

WHERE ARE WE LOCATED?

Corero’s key operational centres are in 
Marlborough, Massachusetts in the USA 
and Edinburgh in Scotland, UK, with the 
Company’s registered office at Salisbury 
House, 29 Finsbury Circus, London, EC2M 
5QQ, UK.

HOw DOeS THe  
TeCHNOLOGY wOrK?  
HOw DO we COMBAT  
DDOS ATTACKS?.

To meet the needs of these customers, 
Corero offers the Smartwall TDS, TDD 
and ETD product lines featuring Deep 
Packet Inspection (‘DPI’), rather than flow 
monitoring, processing packets in real-time, 
in the data path or at the network edge, with 
a high level of automation based on exact 
match and behavioural heuristics-based 
rules. These products deliver highly scalable 
real-time DDoS protection up to tens of 
terabits per second, which makes our cost-
performance ratio superior in the industry.

DDoS mitigation providers typically rely on 
NetFlow monitoring, to identify internet 
traffic anomalies and then re-direct that 
traffic to specialist scrubbing centres (which 
may be on-premises, or in the cloud) where 
the internet traffic can be scrubbed with a 
mix of automatic and manual interventions, 
before the remaining clean traffic is returned 
to its original destination. Corero supports 
this detect-and-redirect model with the 
Smartwall ETD product line. 

Detect and redirect can be ineffective if 
the length of the DDoS attack is short in 
duration. Continued uptime is critical for 
modern businesses impacting, amongst 
other areas, the continuity of their services 
and therefore is fundamental to the 
businesses’ success.

SMARTWALL
Corero’s SmartWall solution is highly 
automated, detecting and mitigating attacks 
surgically without the expensive intervention 
of security analysts or network operators, 
who may not even know the network is 
under attack before SmartWall provides 
an alert to them that it is already blocking 
what would otherwise have been a business 
damaging attack.

With varied deployment topologies 
(in-line, datapath, scrubbing or edge) 
Corero’s SmartWall family of solutions 
utilise innovative, patented technology to 
automatically and surgically remove the 
DDoS attack traffic, leaving good traffic to 
flow unimpeded. 

Protection is available in cost-effective 
scaling increments, from tens-of-gigabits 
to tens-of-terabits, supporting the 
full spectrum of customer bandwidth 
protection requirements. 

We have combined advances in Intel x86 
multicore CPU technology, Data Plane 
Development Kit (‘DPDK’) software for 
packet processing acceleration, and 
high-performance network interface cards 
(‘NICs’), together with an innovative, 
patented, and highly efficient software 
architecture, to develop a new generation 
of physical and virtual appliances providing 
breakthrough price/performance for 
DDoS defence. 

SmartWall appliances perform sampled DPI 
to generate security metadata from traffic 
flows. The internal rules-engines examine 
this metadata to flag offending packet flows 
in real-time and block attacks. At the same 
time, the security metadata is streamed to 
the Corero SecureWatch® Analytics platform, 
where further analysis, involving correlation 
with other performance metrics and event 
data, enables rapid identification of new 
attack vectors. SecureWatch Analytics can 
formulate new mitigation rules for these 
vectors that are distributed out to each 
SmartWall instance.

SECUREWATCH
The Corero SecureWatch service is a 
tiered offering comprised of configuration 
optimisation, monitoring and mitigation 
response services.

Corero’s SecureWatch Analytics application 
leverages Splunk’s analytics engine and 
provides detailed reporting to transform 
Smartwall’s sophisticated DDoS event 
data into easily consumable dashboards 
accessed via a multi-user web GUI. This 
enables customer security analysts to 
monitor and manage incident responses, 
with the ability to conduct sophisticated 
forensic analysis.

The Corero multi-tenant SmartWall Service 
Portal enables a service provider’s customers 
(or ‘tenants’) to gain visibility into attacks 
via per-tenant dashboards. Service provider 
customers can assign tenant service levels 
and automatically distribute reports which 
showcase the value of the protection their 
customers are receiving.

increase

Annualised Recurring Revenues 
(“ARR”) increased 13% to $14.4 million 
as at 1 January 2023 (ARR at 1 January 
2022: $12.8 million), driven by strong 
demand for Corero’s subscription-
based and DDoS Protection as-a-
service (“DDPaaS”) products, which 
increase revenue visibility for the 
Company going forward.

During the final quarter of the year, 
Corero secured several important 
customer wins for its SmartWall® 
DDoS protection solutions including 
additional purchases from existing 
customers and a significant multi-
year support renewal for an existing 
customer. These wins will benefit 
revenues across FY 2023 and 
subsequent years.

iNTrODUCTiON
The Company delivered a credible 
performance across FY 2022.  The 
financial performance was adversely 
impacted by broader macro-economic 
factors and as a consequence, the 
Company saw sales cycles across the 
business lengthen in the second half 
of the year which impacted revenues.  
Nevertheless, the Company delivered 
growth in order intake, and ARR and 
reported another year of EBITDA profit.

The underlying health of the business 
remains robust with order intake, which 
reflects revenues recognised over 
the lifetime of each of the contracts, 
up 13% year-on-year to $23.9 million 
(2021: $21.2 million). Encouragingly, 
new customer order intake increased 
38% over the prior year. This, coupled 
with an exceptional customer support 
contract renewal rate of 98% (2021: 
96%), demonstrates the strength and 
quality of Corero’s market-leading 
solutions, supported by continued 
investment in product development.

OUTLOOK 
The demand for DDoS protection is 
expected to remain strong through 
2023, with attacks becoming increasingly 
sophisticated while at the same time the 
DDoS attack surface is expanding. With 
the number of recorded attacks on the rise 
and shifts in attackers’ motives and goals, 
organisations will need to ensure they have 
robust DDoS defences in place.

The key focus for Corero in 2023 is to 
grow our sales pipeline and revenue. 
The Board is confident that with the 
operational management team in place, 
our market-leading SmartWall® solutions 
and SecureWatch® services, the investment 
in 2022 in sales and marketing initiatives to 
build a stronger go-to-market organisation 
and demand generation targeted to our 
defined Ideal Customer Profile (“ICP”), the 
Company is now well placed to expand 
its market coverage and increase sales of 
SmartWall solutions to new customers. As 
announced by the Company on 13 April 2023, 
Q1 2023 has already seen significant orders 
from both new and existing customers.

The Board remains encouraged by the 
2022 increase in new order intake, existing 
customer expansion and increase in ARR, 
all achieved against a challenging macro-
economic backdrop in the second half  
of 2022.

Jens Montanana
EXECUTIVE CHAIRMAN

24 April 2022

The Board of Directors believes that Corero 
has a built a strong operational team and 
platform, alongside a sales and marketing 
strategy capable of generating sustainable 
growth in the medium term, underpinned by: 

DDOS MARKET DYNAMICS
DDoS attacks continue to be prevalent as 
a means of cyber-attack, as camouflage for 
ransomware attacks and even with Ransom 
driven attacks.

The global DDoS protection market was 
worth c.$3.9 billion in 2022 and is expected 
to reach $7.3 billion by 2027 at a CAGR of 
13.2%. Corero operates within a significant 
segment of this overall market and estimates 
that the total addressable market exceeds 
$2.0bn for its SmartWall solutions. 

The DDoS mitigation marketplace 
continues to grow apace as a result of the 
global acceleration of digitisation and 
the growing need for Service Providers to 
deliver uncompromised network access for 
enterprises to ensure business continuity. 
This is set to continue with the ongoing 
proliferation of IoT devices, the roll-out of 5G 
networks and the increase in cloud services. 

BOARD CHANGES
Neil Pritchard, the former CFO resigned 
from the Board and the Company with effect 
from 30 September 2022. Subsequent to the 
year-end, Lionel Chmilewsky resigned from 
the Board on 28 February 2023. I assumed 
the role of Executive Chairman with effect 
from 15 February 2023, and Andrew Miller 
was appointed Interim Chief Operating 
Officer with effect from 1 March 2023.

• 

Large and high growth addressable 
market;

•  Market leading proprietary technology 
with global customer service capability;

•  Better alignment of the product offering 

to Corero’s Ideal Customer Profile 
(“ICP”);

•  Continued investment in sales and 

channel resources;

•  Scalable and recurring revenue model 

with strong gross margins; and

•  Strong base of existing customers and 

strategic partnerships.

STRATEGIC PROGRESS
The Company made operational advances 
in 2022 with product development and, sales 
and marketing activities driven by a customer 
centric approach. We continued to make 
strategic progress in key areas including:

• 

Increasing our customer base: during 
2022 we added 32 new customers. 

•  Growing strategic alliances: extended 
the Juniper partnership to include the 
PTX router product line and expanded 
our reach and business with GTT.

•  Better monetising our existing services 
and introducing new services: we 
continue to enhance the protection 
and network security visibility for our 
customers.

•  Amplifying our demand generation 
programmes: increased on-line 
advertising and marketing campaigns 
including webinars and thought 
leadership speaking opportunities.

•  Continuing to increase our technological 
innovation leadership: We have invested 
$35 million over 10 years in our market 
leading SmartWall solutions enabling our 
customers to have the most advanced 
DDoS protection, including $1.7 million 
in 2022 to continue to enhance our 
product and competitiveness.

THe COMPANY HAS 
ACHieveD A POSiTive 
eBiTDA

of $2.6 million (2021: $4.0 million), demonstrating the robustness of 
the Company’s business model.

REVENUE AND GROSS MARGINS
Revenue in the year ended 31 December 
2022 reduced slightly year on year from 
$20.9 million in 2021 to $20.1 million in 2022 
due primarily to the timing of order receipts.

The Company’s overall gross margin 
improved in the full year with a margin of 
87.2% (2021: gross margin of 85.1%) driven 
by the difference in revenue mix between 
2022 and 2021. 

Annualised recurring revenues increased 
in the year with ARR of $14.4 million as at 
1 January 2023, driven by growth in DDPaaS 
and software subscription orders (ARR at 
1 January 2022: $12.8 million). 

Software license and appliance revenues 
in particular saw better margin capture 
while other revenue streams recorded 
similar margins to prior periods.

OPERATING EXPENSES  
AND R&D INVESTMENT
After adjusting for $0.6 million PPPL loan 
forgiveness received in 2021, operating 
expenses decreased marginally by  
$0.2 million from $16.7 million to 
$16.5 million. Underlying operating 
expenses, when taking into account the 
debt forgiveness, were level year on year.

OPERATING CASH AND CASH 
EQUIVALENTS
Overall, net cash used in operating  
activities amounted to $1.7 million in the  
year (2021: generation of $2.8 million).  
Cash and cash equivalents excluding the 
impact of exchange rates decreased by  
$5.2 million (2021: increase of $1.2 million).  
This decrease in cash being primarily due 
to the aforementioned repayment of the 
Company’s term debt facility, alongside 
increased working capital investment, due  
to the timing of customer payment cycles,  
which has unwound since the year-end.

Net cash, defined as cash at bank less total 
borrowings, at 31 December 2022 was  
$4.4 million (2021: $8.4 million). Gross cash  
at bank at 31 December 2022 was  
$5.6 million (2021: $11.2 million). 

Borrowings were $1.2 million (2021: $2.8 million), 
comprising a drawn term bank loan facility  
due to be repaid in full by 31 March 2024.

Phil Richards
CHIEF FINANCIAL OFFICER

24 April 2023

Underlying operating expenses included a 
lower depreciation charge of $0.6 million 
(2021: $0.7 million) and lower amortisation 
charge for research and development 
(‘R&D’) of $1.7 million (2021: $1.9 million). 
During the year, the Group enhanced its 
product offerings with new features and 
functionality, with R&D investment of  
$1.7 million (2021: $1.8 million).

Capital expenditures in property plant  
and equipment were level year-on-year  
at $0.4 million (2021: $0.4 million).

Share based payments amounted to 
$0.4 million in 2022 (2021: $0.5 million).

Financing costs were lower in the year 
at $0.3 million (2021: $0.4 million) due 
to the repayment of $1.6 million of the 
Company’s debt facility during the year and 
corresponding decrease in interest costs.

PROFITABILITY
Building on our maiden EBITDA profit in 
2021, I am pleased to report a positive 
EBITDA for the business of $2.6 million in 
2022. Adjusted EBITDA for the year was  
$1.7 million (2021: $3.2 million). Further 
details on these measures are provided in 
the Key Performance Indicators section on 
pages 20 to 21.

Profit after taxation was $0.6 million  
(2021: $1.5 million). Basic and diluted

FOreiGN eXCHANGe FLUCTUATiONS

PeOPLe

To grow and address the challenges resulting from technology 
change and innovation in the DDoS protection market, the 
Company needs to retain and recruit the required sales, 
business development, and software development skills. 
Corero operates in a high growth cyber security market and 
if Corero is unable to recruit and retain the right skills this 
will compromise growth plans. Consequently, Corero targets 
paying salaries in the upper quartile for comparable positions.

Corero’s strategy outlined on page 3 depends on delivering 
revenue growth to meet these ambitions. Clearly, higher order 
intake and related revenue growth provides the opportunity 
for Corero to invest further in its future. Revenue growth is 
highly important to deliver profitable growth for the business. 
Conversely, lower sales growth reduces the Company’s cash 
resources which could impact the Company’s investment in 
sales and marketing and product development and its other 
associated goals.

To deliver this order intake and, as a subset revenue growth, 
Corero needs to identify, meet and exceed customer needs. If 
Corero is not successful in identifying customer prospects with 
a business need Corero can solve, or developing go-to-market 
partner and channel partner relationships which generate revenue, 
this will compromise growth plans and success.

To be successful Corero is:

• 
• 

targeting its Ideal Customer Profile (ICP);
focussing its lead generation and sales resources, and 
product development, on its ICP;

•  working closely with go-to-market partners to grow its sales 
opportunity pipeline, progress sales opportunities and 
generate revenue and cash; and

•  developing relationships with new go-to-market partners 
and channel partners to expand its routes to market.

Past Corero equity fund raises have been in GBP and its debt 
is denominated in GBP. To the extent such funds are required 
to support US dollar denominated funding requirements more 
generally for the Group, the exchange rate value of GBP to 
the value of US dollar may vary, either impacting adversely 
or favourably compared to the denominated funding 
requirements that can be funded from such fund raises. The 
Group mitigates this risk by utilising US denominated funds 
received by the Group’s UK subsidiary to fund the Group’s US 
subsidiary to the extent such funding is required, with the GBP 
funding requirements satisfied from the GBP denominated 
funds generated from GBP equity and debt where possible.

OTHer NON-PriNCiPAL riSKS AND UNCerTAiNTieS

There are a multitude of other risks and uncertainties that face 
companies like Corero, these include: risks and uncertainties 
associated with local legal requirements, political and 
geographic risk, the enforceability of laws and contracts, 
changes in tax laws, terrorist activities, wars and invasions, 
natural disasters and other types of health epidemics. 

TeCHNOLOGY CHANGe AND iNNOvATiON

The DDoS mitigation market is competitive and characterised 
by changes in technology, customer requirements and 
frequent new product introductions and improvements. 
Cybersecurity and DDoS attacks are constantly evolving and 
changing as attackers develop new methods and tools to 
evade defences. 

Corero is focused on its chosen markets and delivering 
continuous innovation by adding new DDoS attack defences 
and new machine learning and artificial intelligence 
capabilities, and striving to provide market leading solutions 
to secure customers from the threat of DDoS attacks.

MArKeT AwAreNeSS

Corero is an emerging player in the DDoS prevention market 
and competes with much larger established organisations. If 
Corero is not successful in connecting with the market and 
raising its profile this will compromise growth plans. To raise 
market awareness of Corero and its DDoS protection solutions, 
the Company will continue to invest in targeted digital 
marketing and lead generation programmes, together with its 
brand awareness programmes.

riSK MANAGeMeNT

The Company operates a risk assessment process, which 
is embedded in day-to-day management and governance 
processes. As part of the annual planning and budgeting 
process, Corero management document the significant 
risks identified, the probability of those risks occurring, their 
potential impact and the plans for managing and mitigating 
each of those risks. 

The Board reviews the annual risk assessment including an 
annual assessment of the effectiveness of the Company’s 
internal control system, comprising financial, operational 
and compliance controls, to ensure that the Company’s risk 
management framework identifies and addresses all relevant 
risks in order to execute and deliver the Company’s strategy. 

The Directors are responsible for the Company’s system of 
internal control and for reviewing its effectiveness, whilst 
the role of management is to implement policies on risk 
management and control. The Company’s system of internal 
control is designed to manage, rather than eliminate, the risk 
of failure to achieve the Company’s business objectives and 
can only provide reasonable, and not absolute, assurance 
against material misstatement or loss.

The Company operates a series of controls to meet its 
needs. These controls include, but are not limited to, the 
annual strategic planning and budgeting process, a clearly 
defined organisational structure with authorisation limits, 
reviews by senior management of monthly financial and 
operating information including comparisons with budgets, 
and forecasts to the Board. Given the size of the Company, 
the Board has concluded it is not appropriate to establish a 
separate, independent internal audit function. The Board will 
keep this under review.

The Audit, Risk and Compliance Committee (‘ARCC’) 
reviews the effectiveness of internal controls. The ARCC 
receives reports from management and observations from 
the external auditors concerning the system of internal 
control and any material control weaknesses. Significant risk 
issues, if any, are referred to the Board for consideration. 
The Corero Risk Register, Auditor’s report, assessment of 
the effectiveness of the internal control system and key 
judgements report for the Annual Report and Accounts are 
tabled and reviewed by the ARCC.

We treat customers, partners, suppliers and employees in a professional, 
courteous and honest manner.
We are committed to complying with environmental, social and governance 
requirements and Corero is dedicated to improving the security and availability 
of the Internet for all.

CORERO’S CULTURE AND 
VALUES
We seek to live our culture and values every 
day, in a dynamic and professional manner. 

Our defined values are: 

Customers First;

Technology Leadership  
& Innovation;

Operational Excellence; 

Integrity; and,

Our People, Empowerment  
& Team Work.

In common with most intellectual property 
technology businesses, we know that the 
expertise, experience, and passion of our 
employees is genuinely what make our 
products and services market leading. 
For example, Corero’s Security Operation 
Centre (‘SOC’) comprises a team of highly 
experienced security analysts whose role it 
is to assist our customers’ IT and security 
teams mitigate the growing number of 
increasingly sophisticated DDoS attacks. 
This service and customer support offering 
is therefore an important competitive 
differentiator. Customers tell us they value 
the service levels and our team regularly 
receives very favourable feedback from 
our customers. 

CORERO’S APPROACH TO 
RESPONSIBLE BUSINESS IN 
SOCIETY

EMPLOYEES, DIVERSITY AND 
INCLUSION AND EMPLOYEE 
INTERACTION

Corero recognises that long-term success 
is underpinned by good relations with its 
key stakeholders, both external (partners, 
suppliers, customers, shareholders, 
regulators and others) and internal 
(employees). As part of Corero’s annual 
planning and budgeting process, the 
Company identifies its stakeholders and 
their respective needs, interests and 
expectations. In addition, the strategy for 
engaging with these stakeholder groups is 
formulated and implemented. 

Corero values feedback from its 
stakeholders and proactively endeavours 
to address any matter identified. Feedback 
is gathered from: customers and partners 
relating to Corero’s products and services 
in an on-going, continuous manner; 
shareholders, through investor relations 
roadshows; and employees as a part of 
regular Company ‘All Hands’ meetings.

Our employees are Corero’s most important 
asset and the continued and sustained 
development of the Company relies on 
its ability to retain and attract high calibre 
employees and we are proud to have so 
many experienced, and talented employees 
in our team. Corero operates an employee 
share option plan, with awards approved by 
the Corero Remuneration Committee. 

The Corero equal opportunities policy 
ensures that all job applicants and 
employees are treated fairly, no matter 
what age, race, colour, gender, religion 
or beliefs, sexual orientation, marital or 
partner status, ethnic origin or community, 
disability, and without favour or prejudice. 
We are committed to applying this policy 
throughout all aspects of employment, 
recruitment and selection, training, 
development and promotion.

The Corero equal opportunity policy has 
been developed to maintain the following 
policy objectives:

•  To provide a safe and welcoming 

environment, in which individuals are 
valued, included and respected

•  To advance equality of opportunity

•  To eliminate unfair discrimination

•  To foster good relations between 

different groups of people

Corporate Directory

We are an increasingly international, 
multi-cultural, gender diverse and diverse 
organisation. For example, many of our 
UK-based software engineers are drawn 
from local universities but also sponsored 
on EU skilled-migrant visas. Inclusion is the 
practice of providing everyone with equal 
access to opportunities and resources. We 
believe employees find an environment 
of understanding and respect at Corero - 
where voices and opinions are heard and 
carefully considered - this is made easier by 
the relatively flat hierarchy and agile nature 
of the business and the values we share. 

Employees are regularly informed of 
matters concerning their interest and the 
financial factors affecting the Company. The 
Company uses company-wide forums to 
communicate matters as well as team and 
individual meetings.

ENVIRONMENTAL 
SUSTAINABILITY
Corero has identified the following UN 
Sustainable Development Goals (SDGs) 
most applicable to its activities listed in the 
table below. 

Corero is committed to promoting 
sustainability. We aim to lead, follow and 
to promote good sustainability practice, 
to carry out our operations in a way which 
manages and minimises any adverse 
environmental impacts from our activities. 

For many years Corero has operated a 
flexible remote working policy before 
remote working was necessitated by the 
COVID-19 pandemic. We aim to mitigate 
unnecessary travel and the impact on 
climate change. 

Our products are used by thousands 
of businesses throughout the world to 
protect against disruptions that could 
have adverse economic, health, well-being 
and environmental consequences for the 
users and customers of those businesses 
(sometimes in a mission critical way) and the 
knock-on effects to populations as-a-whole. 
Disruptions may emanate from individuals, 
groups, corporates or state-sponsored actors. 

Corero is committed to reducing our 
resource consumption where possible. 
Furthermore employees are encouraged 
to be environmentally aware. For example, 
Corero encourages the reuse or recycling 
of office waste, including paper, packaging, 
computer supplies and redundant 
equipment. Company cars are not provided. 

Wherever possible we seek to ensure 
that waste materials are disposed of in 
an environmentally safe manner and in 
accordance with regulations. We aim 
to provide materials such as marketing 
collateral in a paperless, digital way. 

ETHICAL BUSINESS
Corero is committed to the fundamental 
values of integrity, transparency and 
accountability. We have a zero-tolerance 
policy with regard to bribery and corruption 
with reporting mechanisms in place. 
Corero adopts and enacts an Ethics and 
Anti-Bribery Policy to record the ethical 
way in which we conduct business and 
to make our ethical standards clear to 
everyone, including those with whom we do 
business, which includes resellers, agents 
and distributors as well as our customers. 
Corero provides training to all its employees 
on Anti-Bribery and Corruption.

How Corero contributes

Ensuring healthy lives and promoting well-being at all ages is essential to sustainable 
development. We are committed to our people and their wellbeing and are proud of our 
supportive, collaborative culture and strong values.

Obtaining a quality education is the foundation to improving people’s lives and sustainable 
development. Corero’s DDoS protection is favoured by many research and educational 
network customers as a secure way to deliver and promote their objectives.

Sustained and inclusive economic growth can drive progress, create decent jobs for all and 
improve living standards. Corero’s DDoS protection protects the remote working practices, 
being a key feature of post-COVID-19 pandemic ways of working for most employers.

Conflict, insecurity, weak institutions and limited access to justice remain a great threat to 
sustainable development. Corero’s solutions provide cyber protection against nefarious 
activities from individuals, crime and state-sponsored terrorist groups. Corero’s vision is an 
Internet connect world where every business, application and individual is protected from 
DDoS attacks.

Company with effect from 30 September 2022. There were no other 
changes to the board composition during 2022. Subsequent to 
the year-end, Lionel Chmilewsky resigned from the Board on 28 
February 2023. I assumed the role of Executive Chairman with effect 
from 15 February 2023, and Andrew Miller was appointed Interim 
Chief Operating Officer with effect from 1 March 2023. 

STAKEHOLDER ENGAGEMENT
We seek to maintain an open dialogue with all stakeholders 
including shareholders, customers, partners, suppliers and our 
employees, even in these on-going uncertain times with the global 
pandemic. Details of our stakeholders along with details of the 
forms of engagement undertaken by the Board are set out on pages 
22 to 23.

In this context, I would like to give my continued thanks to our 
institutional and private investors for their continued support; to 
all wider stakeholders including our customers, strategic partners 
and suppliers; and thank you as ever to all our employees for their 
determination, integrity and commitment to Corero. 

LOOKING FURTHER AHEAD
Corero has delivered a stable performance in 2022 across many 
metrics. The expectation of strong forecast growth in the DDoS 
market underpins the Board’s continued confidence, alongside 
Corero’s improved sales execution in the target ICP, and superior 
technological solution in that marketplace. To capitalise on this, we 
will continue investment in 2023 to deliver our strategic goals with 
the objective of creating long-term values for all our stakeholders.

Jens Montanana
EXECUTIVE CHAIRMAN

24 April 2023

As an AIM-listed company, Corero adopts the principles of the Quoted Companies Alliance Corporate Governance Code (the ‘QCA 
Code’). The QCA Code identifies ten principles to be followed in order for companies to deliver growth in long-term shareholder value, 
encompassing an efficient, effective and dynamic management framework accompanied by good communication to promote confidence 
and trust. The following explains how Corero follows those QCA Code principles:

1 Establish a strategy and 

business model to promote 
long-term value for 
shareholders

2 understand and meet 

shareholder needs and 
expectations

3 Take into account wider 

stakeholder and social 
responsibilities and their 
implications for long-term 
success

4 Embed effective risk 

management, considering both 
opportunities and threats, 
throughout the organisation

5 Maintain the Board as a  

well-functioning, balanced  
team led by the Chair

Corero’s strategy is focused on being the leader in real-
time, high performance DDoS protection and scaling the 
business for profitability though revenue growth.

For more information please see 
pages 4 and 5.

The Executive Chairman and CFO communicate regularly 
with shareholders, investors and analysts, including at our 
full year and half-yearly results roadshows. The full Board is 
available at the AGM to communicate with shareholders.

Shareholders, our customers, partners and employees are 
our most important stakeholders. We engage with these 
communities via regular communications in our day-to-day 
activities, and via formal feedback requests.

Company is governed and is 
performing by maintaining a 
dialogue with shareholders and

the Board to stand back and assess its strengths and areas 
for development.

direction and management, and for the establishment and 
maintenance of a framework of delegated authorities and

INTRODUCTION
An annual Board effectiveness review is undertaken to enable 
the Board to stand back and assess its strengths and areas for 
development. This review is conducted internally.

The Board may refresh the performance assessment process based 
on external advice and if appropriate engage a third-party facilitator 
to assist in the performance of such effectiveness reviews every 
three years. 

The Remuneration Committee’s (‘RC’) remit is to measure the 
performance of and determine the remuneration policy relating 
to Directors and senior employees. To support this responsibility, 
it has access to professional and other advice external to the 
Group. Taking the performance factors into account, it then makes 
recommendations to the Board.

To assist the work of the RC, the views of the Executive Chairman 
and Chief Financial Officer are also invited where appropriate. 
However, they do not participate in any decision related to their  
own remuneration.

The Nomination Committee reviews and recommends nominees as 
new Directors to the Board. Senior management appointments are 
required to be approved by the RC.

The Group is committed to the governing objective of maximising 
shareholder value over time. Each year the remuneration framework 
and the packages of the Directors are reviewed to ensure they 
continue to achieve this objective.

The Group operates in the cyber security market which is a market 
with significant growth potential. It is also a competitive market with 
a number of companies who are significantly larger than Corero. 
The Group’s Executive Director remuneration policy is designed to 
attract and retain Directors of the calibre required to maintain the 
Group’s position in its marketplace. This is maintained through the 
use of bonus and share option schemes, as follows.

BONUS
A cash bonus designed to incentivise specific short-term financial 
goals. Goals and objectives are set for the Executive Directors 
based on key financial performance metrics. The Chief Technology 
Officer on-target bonus is set at two-thirds of base salary and the 
Chief Financial Officer is set at one half of base salary. 

SHARE OPTIONS
Share options are granted to encourage and reward delivery of the 
Company’s long-term strategic objectives and provide alignment 
with shareholders through the use of share-based incentives. 

All share-based incentives offered to Directors have a three year 
vesting schedule, with one-third vesting on the first anniversary of 
the grant/start date, a further third on the second anniversary of the 
grant/start date and the final third the third anniversary of the grant/
start date. Shares acquired on the exercise of options may not be 
sold until the second anniversary of the grant date. Share options 
are granted with an exercise price set at the higher of market price 
or such other price as determined by the RC.

CONFLICTS OF INTEREST
The members of the RC do not have any conflicts from cross-
directorships that relate to the business of the Committee. The 
members of the RC do not have any day-to-day involvement in the 
running of the Group.

BOARD CHANGES
Given Corero’s size, the Company does not have internal succession 
candidates for the Executive Directors. In the event an Executive 
Director replacement is required, the Company would seek to 
recruit a replacement through a recruitment search process. The 
Board is satisfied that the Company’s middle management will 
ensure the Company’s business is not adversely impacted in the 
period between an Executive Director leaving and a replacement 
being recruited.

The Board has three established Committees: 

•  Audit, Risk and Compliance Committee: responsible 
for reviewing the Group’s interim and year end results 
announcements, and the Annual Report and Accounts; 
determining the application of the financial reporting and 
internal control and risk management procedures and assessing 
the scope, quality and results of the external audit.

•  Remuneration Committee: responsible for the policy for the 

remuneration of the Executive Directors and senior management; 
setting the remuneration of the Executive Directors, determining 
the payment of bonuses to Executive Directors; and approving 
the Company’s bonus and incentive arrangements for employees. 

•  Nomination Committee: responsible for reviewing the 

composition, structure and size of the Board; assessing the 
leadership needs of the Group; and recommending nominees 
as new Directors to the Board. 

AUDIT, RISK AND COMPLIANCE COMMITTEE 
(‘ARCC’) REPORT
The ARCC members comprise Richard Last, who is the Committee 
Chairman, and member Peter George, and meets at least twice a 
year. The Company’s Chief Financial Officer and Group Financial 
Controller, and the Company’s external auditors attend the meetings. 

In the year ended 31 December 2022, the ARCC met on two 
occasions. The attendance of individual Committee members at 
ARCC meetings in the year to 31 December 2022 is shown in the 
table below:

Meetings attended

Post the year-end, and in line with good governance practice, the 
ARCC led a competitive audit tender process for the 2023 Group 
audit. As a result of this, the ARCC recommended the Board of 
Directors propose a change of auditors at the forthcoming AGM, 
with BDO to stand down as auditors following the completion of the 
2022 year-end audit.

The RC comprises Peter George, and members Jens Montanana 
and Richard Last. The RC meets at least twice a year.

GROUP RESULTS
The Group’s Income Statement on page 46 shows a profit for the 
year of $0.6 million (2021: profit of $1.5 million).

On this basis, the Directors have therefore concluded that it 
is appropriate to prepare the financial statements on a going 
concern basis.

DIRECTORS’ SHAREHOLDINGS

GOING CONCERN
The financial position and cash flows are described in the Financial 
Review on page 18. An indication of likely future developments 
affecting the Company is included in the Strategic Report on pages 
16 to 27.

The Directors have prepared detailed income statement, balance 
sheet and cash flow projections for the period to 30 April 2024 
(“going concern assessment period”). The cash flow projections 
have been subjected to sensitivity analysis of the revenue, cost 
and combined revenue and cost levels which demonstrate that the 
Group and Company will maintain a positive cash balance through 
the going concern assessment period. As part of the sensitivity 
analysis, the Directors have noted that should the forecasted 
revenues not be achieved, mitigating actions can be taken to 
address any cash flow concerns. These actions include the utilisation 
of the undrawn revolving credit facility of £1 million, deferral of 
capital expenditure, reduction in marketing and other variable 
expenditure alongside a hiring freeze. In addition, the projections 
confirm that the bank loan covenants will be met during the going 
concern assessment period.

The Directors are also not aware of any significant matters in  
the remainder of calendar 2024 that occur outside the going 
concern period that could reasonably possibly impact the going 
concern conclusion.

The Directors have also considered the geo-political environment, 
including rising inflation in some of our key markets and the conflict 
in Ukraine, and whilst the impact on the Group is currently deemed 
minimal, the Directors remain vigilant and ready to implement 
mitigation action in the event of a downturn in demand or an impact 
on operations.

DIVIDENDS
The Directors have not recommended a dividend (2021: $nil). 

SHARE CAPITAL
The issued share capital of the Company, together with details 
of movements in the Company’s issued share capital during the 
financial period are shown in note 22 to the financial statements. 
As at the date of this report, 499,953,971 ordinary shares of 1p each 
(‘ordinary shares’) were in issue and fully paid with an aggregate 
nominal value of $7.0 million.

The market price of the ordinary shares at 31 December 2022 was 
9.3p and the shares traded in the range 9.3p to 14.5p during the 
year (as at 31 December 2021 was 12.5p and the shares traded in 
the range 9.0p to 16.0p during the year ended 31 December 2021). 

ISSUE OF SHARES POWERS AT THE AGM
At the AGM held on 9 June 2022, shareholders granted authority 
to the Board under the Articles and section 551 of the Companies 
Act 2006 (the ‘Act’) to exercise all powers of the Company to 
allot relevant securities up to an aggregate nominal amount of 
£1,649,507.68. 

Also at the AGM held on 9 June 2022, shareholders granted 
authority to the Board under the Articles and section 570(1) of the 
Act to exercise all powers of the Company to allot equity securities 
wholly for cash up to an aggregate nominal amount of £494,852.30 
without application of the statutory pre-emption rights contained in 
section 561(1) of the Act.

DIRECTORS’ INDEMNITIES
The Company has qualifying third party indemnity provisions in 
place for the benefit of its Directors. These remain in force at the 
date of this report.

DIRECTORS AND DIRECTORS’ INTERESTS
The Directors who served in office during the year and up to the 
date of this report and their interests in the Company’s shares were 
as above. 

The biographical details of the current Directors of the Company are 
set out on pages 28 and 29.

Details of the share options held by Directors are shown in note 27 
to the financial statements.

FINANCIAL RISK MANAGEMENT OBJECTIVES 
AND POLICIES
The Group’s business activities expose it to a variety of financial 
risks. The policies for managing these risks are described below: 

• 

Liquidity risk – arises from the Group’s management of working 
capital and finance charges. It is a risk that the Group will 
encounter difficulty in meeting its financial obligations, including 
its covenants and a repayment term bank loan drawn down by 
the Company in April 2022 ($1.2 million at 31 December 2022) 
details of which are set out in note 18, as they fall due. Liquidity 
risk is managed by the Finance function. Annual budgets 
are agreed by the Board, enabling the Group’s cash flow 
requirements to be anticipated.

•  Credit risk – arises from cash and cash equivalents and 

from credit exposures to the Group’s customers including 
outstanding receivables and committed transactions. Credit 
risk is managed with regular reports of exposures reviewed 
by management. The Group does not set individual credit 
limits but seeks to ensure that customers enter into legally 
enforceable contracts that include settlement terms that 
demonstrate the customers’ commitment to the transaction and 
minimise this risk exposure.

The amounts of trade receivables presented in the Statement of 
Financial Position are shown net of allowances for doubtful accounts 
estimated by management based on prior experience and their 
assessment of the current economic environment (note 15). 

The Group has no significant concentration of credit risk, with 
exposure spread over a number of customers. 

The credit risk on liquid funds and financial instruments is limited 
because the counterparties are banks with acceptable credit ratings 
assigned by international credit rating agencies. 

•  Cash flow interest rate risk – the Group’s policy is to as far as 
possible minimise interest rate cash flow risk exposure on its 
financing. The Group is exposed to interest rate increases on 
the term bank loan ($1.2 million at 31 December 2022) details 
of which are set out in note 18, which bears interest at UK base 
rate plus 6.5%. The bank loan does not have early repayment 
penalties and thus the Group can if GBP interest rates increase 
to punitive levels, seek to refinance the loan. The Group’s 
policy is to balance the risk in relation to cash balances held 
by spreading these across a number of financial institutions as 
opposed to maximising interest income.

•  Currency risk – there was no material impact from trading 
currency risk on the Group’s profit or loss for the year from 
exchange rate movements, as foreign currency transactions are 
entered into by Group companies whose functional currency 
is aligned with the currencies in which it transacts. Exchange 
rate risks do arise in relation to (i) the bank loan which is GBP 
denominated and equity fund raises which are in GBP, given the 
Company’s AIM listing, to the extent such funds are required to 
support US dollar denominated funding requirements, and (ii) 
GBP denominated obligations of the Group given the invoicing 
currency of the Group is US dollar denominated. The Group 
has not hedged such GBP debt and equity fund raises or GBP 
denominated expenses in the past as US denominated funds 
received by the Group’s UK subsidiary have been used to fund 
the Group’s US subsidiary to the extent such funding has been 
required, with the GBP funding requirements satisfied from the 
GBP denominated funds generated from GBP debt and equity 
fund raises. The Group keeps this policy under review based on 
the expected timing of US dollar and GBP operational funding 
requirements.

The principal risk which applies to the Parent Company’s financial 
statements is the risk that the returns generated by the subsidiaries 
might not support the carrying value of the cost of the investments 
in subsidiaries. The carrying value is tested at least annually for 
impairment and, if necessary, impaired as appropriate.

CAPITAL MANAGEMENT
The Group monitors its available capital, which it considers to be all 
components of equity against its expected requirements. 

The Group’s objectives when maintaining capital are to safeguard 
the entity’s ability to continue as a going concern, so that it can 
continue to provide returns for shareholders and benefits for other 
stakeholders, and to ensure that sufficient funds can be raised 
for investing activities. In order to maintain or adjust the capital 
structure, the Company may return capital to shareholders, issue 
new shares, or sell assets. The Group does not review its capital 
requirements according to any specified targets or ratios.

TREASURY MANAGEMENT 
The objectives of Group treasury policies are to ensure that 
adequate financial resources are available for development of 
the business while at the same time managing financial risks. 
Financial instruments may be used to reduce financial risk 
exposures arising from the Group’s business activities and not 
for speculative purposes.

The Group’s treasury activities are managed by the Group Financial 
Controller who reports to the Board on the implementation of the 
Group treasury policy.

ENVIRONMENT
The Group’s activities are primarily office-based and as such the 
Directors believe that there is no significant environmental impact 
arising from the Group’s activities. The Group complies with local 
WEEE regulations. No environmental performance indicators are 
therefore included within this report. The Group’s environmental 
policy states: “We endeavour to recycle appropriate materials where 
possible and to efficiently use natural resources and energy supplies 
so as to minimise our environmental impact. We will comply with 
the relevant statutes and legislation. Furthermore, employees 
are encouraged to be environmentally aware. Company cars are 
not provided.”

RESEARCH AND DEVELOPMENT
The development of computer software is an integral part of the 
Group’s business and the Group continues to develop its software 
in response to user demand, and particularly the changing IT 
security threat landscape. During the year the Group enhanced 
the features and functionality of its existing products. A capital 
investment of $1.7 million (2021: $1.8 million) was made during the 
year. Amortisation of $1.7 million (2021: $1.9 million) and costs not 
capitalised of $1.7 million (2021: £1.5 million) were charged to the 
Group Income Statement during the year. 

EMPLOYEES
The quality and commitment of the Group’s employees has 
played a major role in the Company’s continued progress. This 
has been demonstrated in many ways, including strong customer 
satisfaction, the development of new product offerings and the 
flexibility employees have shown in adapting to changing business 
requirements. The Group operates sales commission, incentive 
bonus plans and share option plans to provide incentives for 
achievements which add value to the business.

ANNUAL GENERAL MEETING
Notice of the AGM together with details of the business to be 
considered will be sent to shareholders in due course. 

AUDITORS
In so far as each Director is aware:

• 

• 

there is no relevant audit information of which the Company’s 
auditors are unaware; and

the Directors have taken all the steps that they ought to 
have taken to make themselves aware of any relevant audit 
information and to establish that the Company’s auditors are 
aware of that information.

Following a competitive tender process, the Directors will  
recommend a change of auditors at the forthcoming AGM.  
As a result, BDO will be standing down as auditors following  
the completion of the 2022 year-end audit. 

By order of the Board

Duncan Swallow
COMPANY SECRETARY

24 April 2023

The Directors are responsible for keeping adequate accounting 
records that are sufficient to show and explain the Group’s 
transactions and disclose with reasonable accuracy at any time the 
financial position of the Group and enable them to ensure that the 
financial statements comply with the Companies Act 2006. They are 
also responsible for safeguarding the assets of the Group and hence 
for taking reasonable steps for the prevention and detection of 
fraud and other irregularities. 

The Directors are responsible for ensuring the Annual Report and 
the financial statements are made available on a website. Financial 
statements are published on the Company’s website in accordance 
with legislation in the United Kingdom governing the preparation 
and dissemination of financial statements, which may vary from 
legislation in other jurisdictions. The maintenance and integrity of 
the Company’s website is the responsibility of the Directors. The 
Directors’ responsibility also extends to the on-going integrity of the 
financial statements contained therein.

The Directors are responsible for preparing the Annual Report  
and Financial Statements in accordance with applicable law  
and regulations.

Company law requires the Directors to prepare financial statements 
for each financial year. Under that law the Directors have elected 
to prepare the Group financial statements in accordance with UK 
adopted international accounting standards in conformity with 
the requirements of the Companies Act 2006. The Directors have 
chosen to prepare the Company financial statements in accordance 
with FRS101. Under company law the Directors must not approve 
the financial statements unless they give a true and fair view of the 
state of affairs of the Group and Parent Company and of the profit 
or loss of the Group for that period. The Directors are also required 
to prepare financial statements in accordance with the rules of 
the London Stock Exchange for companies trading securities on 
the AIM. In preparing these financial statements, the Directors are 
required to: 

• 

select suitable accounting policies and then apply  
them consistently;

•  make judgements and estimates that are reasonable  

and prudent;

• 

state whether they have been prepared in accordance with  
UK adopted international accounting standards in conformity 
with the requirements of the Companies Act 2006, subject to 
any material departures disclosed and explained in the financial 
statements; and

•  prepare the financial statements on the going concern basis 
unless it is inappropriate to presume that the Group will 
continue in business.

TO THe MeMBerS OF COrerO NeTwOrK SeCUriTY PLC

OPINION ON THE FINANCIAL STATEMENTS
In our opinion:

• 

• 

• 

• 

the financial statements give a true and fair view of the state 
of the Group’s and of the Parent Company’s affairs as at 31 
December 2022 and of the Group’s profit for the year then ended;

the Group financial statements have been properly prepared in 
accordance with UK adopted international accounting standards;

the Parent Company financial statements have been properly 
prepared in accordance with United Kingdom Generally 
Accepted Accounting Practice; and

the financial statements have been prepared in accordance with 
the requirements of the Companies Act 2006.

We have audited the financial statements of Corero Network 
Security plc (the ‘Parent Company’) and its subsidiaries (the 
‘Group’) for the year ended 31 December 2022 which comprise 
the Consolidated Income Statement, the Consolidated Statement 
of Comprehensive Income, the Consolidated and Company 
Statements of Financial Position, the Consolidated Statement of 
Cash Flows, the Consolidated and Company Statements of Changes 
in Equity and notes to the financial statements, including a summary 
of significant accounting policies. 

The financial reporting framework that has been applied in the 
preparation of the Group financial statements is applicable law 
and UK adopted international accounting standards. The financial 
reporting framework that has been applied in the preparation of the 
Parent Company financial statements is applicable law and United 
Kingdom Accounting Standards, including Financial Reporting 
Standard 101 Reduced Disclosure Framework (United Kingdom 
Generally Accepted Accounting Practice).

BASIS FOR OPINION
We conducted our audit in accordance with International Standards 
on Auditing (UK) (ISAs (UK)) and applicable law. Our responsibilities 
under those standards are further described in the Auditor’s 
responsibilities for the audit of the financial statements section of 
our report. We believe that the audit evidence we have obtained is 
sufficient and appropriate to provide a basis for our opinion.

Independence
We remain independent of the Group and the Parent Company 
in accordance with the ethical requirements that are relevant 
to our audit of the financial statements in the UK, including the 
FRC’s Ethical Standard as applied to listed entities, and we have 
fulfilled our other ethical responsibilities in accordance with these 
requirements. 

CONCLUSIONS RELATING TO GOING CONCERN
In auditing the financial statements, we have concluded that the 
Directors’ use of the going concern basis of accounting in the 
preparation of the financial statements is appropriate. 

Given our assessment of risk and the significance of this area, we 
have determined going concern to be a key area of focus for the 
audit. Our evaluation of the Directors’ assessment of the Group’s 
and the Parent Company’s ability to continue to adopt the going 
concern basis of accounting and response to the key audit matter is 
included in the ‘Key Audit Matters’ section below.

Based on the work we have performed, we have not identified 
any material uncertainties relating to events or conditions that, 
individually or collectively, may cast significant doubt on the Group 
and the Parent Company’s ability to continue as a going concern 
for a period of at least twelve months from when the financial 
statements are authorised for issue. 

Our responsibilities and the responsibilities of the Directors with 
respect to going concern are described in the relevant sections of 
this report.

AN OVERVIEW OF THE SCOPE OF OUR AUDIT
Our Group audit was scoped by obtaining an understanding of the Group and its environment, including the Group’s system of internal 
control, and assessing the risks of material misstatement in the financial statements. We also addressed the risk of management override  
of internal controls, including assessing whether there was evidence of bias by the Directors that may have represented a risk of  
material misstatement.

Based on our assessment of the Group, we determined there to be three significant components, Corero Network Security plc, Corero 
Network Security, Inc. and Corero Network Security (UK) Limited each of which were subject to full scope audits by the Group audit team. 
Corero Group Services Limited was considered a non-significant component, but was subject to a full scope audit for statutory purposes, 
contributing to the overall Group coverage obtained. 

Key audit matters
Key audit matters are those matters that, in our professional judgement, were of most significance in our audit of the financial statements of 
the current period and include the most significant assessed risks of material misstatement (whether or not due to fraud) that we identified, 
including those which had the greatest effect on: the overall audit strategy, the allocation of resources in the audit, and directing the efforts 
of the engagement team. These matters were addressed in the context of our audit of the financial statements as a whole, and in forming 
our opinion thereon, and we do not provide a separate opinion on these matters.

Key audit matter 

Revenue 
recognition

See accounting 
policy at note 2.5, 
the key accounting 
estimate at note 3.2 
and note 4.

How the scope of our audit addressed the key audit matter

Our procedures included the following:

•  We gained an understanding of the Group’s methodology in determining 

the fair value of the different deliverables in multiple element arrangements 
and assessed the appropriateness of this through review of accounting 
policies against the applicable accounting standard, IFRS 15. For a sample of 
transactions we recalculated the Group’s determination of the fair value of the 
different deliverables in multiple element arrangements as set out in note 2.5 of 
the financial statements, to check that it provided a suitable basis on which to 
recognise revenue.

•  For a sample of revenue transactions around the year end, we corroborated to 
supporting documentation, including invoice, underlying contract, subsequent 
receipt through the bank statement and associated evidence of satisfaction of 
the obligation, recalculating the accompanying revenue and deferred revenue 
where applicable to verify that revenue was recorded in the correct period. 

•  We assessed the basis upon which performance obligations were recognised for 
each revenue stream and compared this to the requirements of the applicable 
accounting standards, industry practice, and the Group’s specific circumstances.

•  We also tested on a sample basis the accuracy of the deferred income balance 
through corroborating to supporting documentation, including invoice, along 
with testing a sample of transactions around the year-end to supporting 
documentation, including invoice and proof of delivery to verify that they were 
recorded in the correct period.

Key observations: Based on the work performed we consider that the Group’s 
revenue recognition accounting policy is appropriate, and that revenue has been 
recognised in accordance with the Group’s revenue policy. 

The Group generates 
revenue primarily from 
the sale of hardware and 
associated software and 
related maintenance and 
support contracts. 

It does this directly through 
arrangements with end-users 
(either through the sale of 
hardware and a software 
licence or by selling the 
software as a service) as  
well as through distributors. 
The sales of licences may 
be on a perpetual or a fixed 
term basis.

We considered there to be a 
significant audit risk arising 
from the allocation of the 
value of the transaction price 
to the individual performance 
obligations included in the 
sale as well as the timing 
of revenue recognition 
with regard to appropriate 
recognition of point in time 
revenue recognised around 
the year end due to the 
potential material impact of 
these transactions.

Key audit matter 

Going concern

See note 2.2.

The financial performance 
of the Group was adversely 
impacted by broader macro-
economic factors. This 
has continued to have an 
impact on the Group’s future 
expected cash flows, with a 
consequent impact on the 
going concern assessment. 

In addition, as described in 
note 18, the Group has loan 
covenant requirements to 
adhere to in connection with 
its financing.

Whilst the directors’ 
assessment in relation 
to going concern did 
not identify any material 
uncertainties in this respect 
we nevertheless considered 
going concern to be a 
significant risk and a key 
audit matter.

How the scope of our audit addressed the key audit matter

In assessing the director’s review of the going concern assumption within the 
financial statements, we have undertaken the following audit procedures:

•  Confirming the mathematical accuracy of the underlying calculations in  

the forecasts.

•  Analysing the directors’ assessment of going concern based upon the Group’s 

cash flow forecasts through to 30 April 2024. This included assessing and 
challenging assumptions with reference to historic experience and recent 
contract wins made in relation to revenues, expenses, and the associated cash 
flows and any other cash related assumptions. Further, we checked actual results 
for FY 2022 against budget to review the accuracy of management’s historic 
forecasts and we compared the forecast against available post year-end trading 
and cash flow results; 

•  We reviewed the bank loan documents to understand the terms and covenants 
which the Group and Parent Company is required to comply with, comparing 
these to the Group’s forecasts;

•  We recalculated and confirmed management’s covenant compliance 
calculations for the period under audit, and assessed future covenant 
compliance using the Directors’ forecasts and compared them to the covenants 
in place;

•  We made inquiries of the Directors as to their knowledge of events or 

conditions beyond the period of their assessment that may cast significant 
doubt on the entity’s ability to continue as a going concern.

•  We considered whether any post-balance sheet events had occurred, which may 

impact going concern. 

•  We assessed the adequacy of the disclosures in the financial statements (see 
note 2.2) with reference to our knowledge of the business and information 
obtained in performing our procedures.

Our conclusion in respect of going concern is included within the “Conclusions 
relating to going concern” section of this report on page 40.

OUR APPLICATION OF MATERIALITY
We apply the concept of materiality both in planning and performing our audit, and in evaluating the effect of misstatements. We consider 
materiality to be the magnitude by which misstatements, including omissions, could influence the economic decisions of reasonable users 
that are taken on the basis of the financial statements. 

In order to reduce to an appropriately low level the probability that any misstatements exceed materiality, we use a lower materiality level, 
performance materiality, to determine the extent of testing needed. Importantly, misstatements below these levels will not necessarily 
be evaluated as immaterial as we also take account of the nature of identified misstatements, and the particular circumstances of their 
occurrence, when evaluating their effect on the financial statements as a whole. 

Overview

Based on our professional judgement, we determined materiality for the financial statements as a whole and performance materiality as

Revenue was considered to be the 
most appropriate benchmark as it is a 
consistent indicator of the performance 
of the Group for users of the financial 
statements. 

The materiality of the Parent Company 
was capped at a percentage of Group 
materiality to respond to aggregation 
risk.

Basis for determining performance materiality

75% of Group materiality 

75% of Parent Company materiality

Rationale for the percentage applied for 
performance materiality

75% of materiality - this was set with 
reference to the level of adjustments 
identified in the prior year, planned 
nature of testing and the size and 
complexity of the Group. 

75% of parent company materiality – 
this was set with reference to the level 
of adjustments identified in the prior 
year and the planned nature of testing. 

Component materiality
For the purposes of our Group audit opinion, we set materiality for each significant component of the Group, apart from the Parent 
Company whose materiality is set out above, based on a percentage of between 93% and 31% (2021: 95% and 25%) of Group materiality 
dependent on the size and our assessment of the risk of material misstatement of that component. Component materiality ranged from 
$370,000 to $125,000 (2021: $397,000 to $105,937). In the audit of each component, we further applied performance materiality levels 
of 75% (2021: 75%) of the component materiality to our testing to ensure that the risk of errors exceeding component materiality was 
appropriately mitigated.

Reporting threshold 
We agreed with the Audit Committee that we would report to them all individual audit differences in excess of $20,000 (2021: $20,900). We 
also agreed to report differences below this threshold that, in our view, warranted reporting on qualitative grounds.

OTHER INFORMATION
The directors are responsible for the other information. The other information comprises the information included in the Annual Report 
and Accounts other than the financial statements and our auditor’s report thereon. Our opinion on the financial statements does not 
cover the other information and, except to the extent otherwise explicitly stated in our report, we do not express any form of assurance 
conclusion thereon. Our responsibility is to read the other information and, in doing so, consider whether the other information is materially 
inconsistent with the financial statements or our knowledge obtained in the course of the audit, or otherwise appears to be materially 
misstated. If we identify such material inconsistencies or apparent material misstatements, we are required to determine whether this gives 
rise to a material misstatement in the financial statements themselves. If, based on the work we have performed, we conclude that there is 
a material misstatement of this other information, we are required to report that fact.

We have nothing to report in this regard.

OTHER COMPANIES ACT 2006 REPORTING
Based on the responsibilities described below and our work performed during the course of the audit, we are required by the Companies 
Act 2006 and ISAs (UK) to report on certain opinions and matters as described below.

Strategic report and Directors’ report 

Matters on which we are required to report by exception

In our opinion, based on the work undertaken in the course of the 
audit:

•  the information given in the Strategic report and the Directors’ 

report for the financial year for which the financial statements are 
prepared is consistent with the financial statements; and

•  the Strategic report and the Directors’ report have been prepared in 

accordance with applicable legal requirements.

In the light of the knowledge and understanding of the Group and 
Parent Company and its environment obtained in the course of the 
audit, we have not identified material misstatements in the strategic 
report or the Directors’ report.

We have nothing to report in respect of the following matters in 
relation to which the Companies Act 2006 requires us to report to you 
if, in our opinion:

•  adequate accounting records have not been kept by the Parent 

Company, or returns adequate for our audit have not been received 
from branches not visited by us; or

•  the Parent Company financial statements are not in agreement with 

the accounting records and returns; or

•  certain disclosures of Directors’ remuneration specified by law are 

not made; or

•  we have not received all the information and explanations we 

require for our audit.

RESPONSIBILITIES OF DIRECTORS
As explained more fully in the statement of Directors’ responsibilities, the Directors are responsible for the preparation of the financial 
statements and for being satisfied that they give a true and fair view, and for such internal control as the Directors determine is necessary to 
enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the financial statements, the Directors are responsible for assessing the Group’s and the Parent Company’s ability to continue 
as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the 
Directors either intend to liquidate the Group or the Parent Company or to cease operations, or have no realistic alternative but to do so.

AUDITOR’S RESPONSIBILITIES FOR THE AUDIT OF THE FINANCIAL STATEMENTS
Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, 
whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, 
but is not a guarantee that an audit conducted in accordance with ISAs (UK) will always detect a material misstatement when it exists. 
Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be 
expected to influence the economic decisions of users taken on the basis of these financial statements.

Extent to which the audit was capable of detecting irregularities, including fraud
Irregularities, including fraud, are instances of non-compliance with laws and regulations. We design procedures in line with our 
responsibilities, outlined above, to detect material misstatements in respect of irregularities, including fraud. The extent to which our 
procedures are capable of detecting irregularities, including fraud is detailed below:

Overview

Strategic Report

GOverNANCe

Financial Statements

Corporate Directory

Non-compliance with laws and regulations
Based on:

•  Our understanding of the Group and the industry in which it 

operates;

•  Discussion with management and those charged with 

governance; and

•  Obtaining and understanding of the Group’s policies and 

procedures regarding compliance with laws and regulations,

we considered the significant laws and regulations which are directly 
relevant to specific assertions in the financial statements are those 
that relate to the applicable reporting frameworks, Companies Act 
2006, the AIM rules, data privacy and the relevant tax regulations 
including but not limited to, Corporate and VAT legislation, and 
Employment Taxes.

Our procedures in respect of the above included:

•  Review of minutes of meeting of those charged with governance 
for any instances of non-compliance with laws and regulations; 

•  Review of financial statement disclosures and agreeing to 

supporting documentation; and

•  Review of legal expenditure accounts to understand the nature 

of expenditure incurred.

Fraud
We assessed the susceptibility of the financial statements to 
material misstatement, including fraud. Our risk assessment 
procedures included:

•  Enquiry with management and those charged with governance 

regarding any known or suspected instances of fraud;

•  Obtaining an understanding of the Group’s policies and 

procedures relating to:

 — Detecting and responding to the risks of fraud; and 

 — Internal controls established to mitigate risks related  

to fraud. 

•  Review of minutes of meeting of those charged with governance 

for any known or suspected instances of fraud;

•  Discussion amongst the engagement team as to how and where 

fraud might occur in the financial statements;

•  Performing analytical procedures to identify any unusual or 
unexpected relationships that may indicate risks of material 
misstatement due to fraud; and 

•  Considering remuneration incentive schemes and performance 
targets and the related financial statement areas impacted  
by these.

Our procedures in respect of the above included:

• 

In response to the risk of fraud in revenue recognition, the 
procedures set out in the key audit matters section of the report.

•  Testing a sample of journal entries throughout the year, 

which met a defined risk criteria, by agreeing to supporting 
documentation; and 

•  Assessing significant estimates made by management for bias.

We also communicated relevant identified laws and regulations and 
potential fraud risks to all engagement team members who were 
all deemed to have appropriate competence and capabilities and 
remained alert to any indications of fraud or non-compliance with 
laws and regulations throughout the audit. 

Our audit procedures were designed to respond to risks of material 
misstatement in the financial statements, recognising that the risk 
of not detecting a material misstatement due to fraud is higher 
than the risk of not detecting one resulting from error, as fraud 
may involve deliberate concealment by, for example, forgery, 
misrepresentations or through collusion. There are inherent 
limitations in the audit procedures performed and the further 
removed non-compliance with laws and regulations is from the 
events and transactions reflected in the financial statements, the less 
likely we are to become aware of it.

A further description of our responsibilities is available on 
the Financial Reporting Council’s website at: www.frc.org.uk/
auditorsresponsibilities. This description forms part of our  
auditor’s report.

USE OF OUR REPORT
This report is made solely to the Parent Company’s members, as a 
body, in accordance with Chapter 3 of Part 16 of the Companies Act 
2006. Our audit work has been undertaken so that we might state 
to the Parent Company’s members those matters we are required 
to state to them in an auditor’s report and for no other purpose. 
To the fullest extent permitted by law, we do not accept or assume 
responsibility to anyone other than the Parent Company and the 
Parent Company’s members as a body, for our audit work, for this 
report, or for the opinions we have formed.

1. GENERAL INFORMATION
Presentation currency
These consolidated financial statements are presented in US dollars (‘$’) rounded to the nearest $’000 unless otherwise stated which 
represents the presentational currency of the Group.

The average $-GBP sterling (‘GBP’) exchange rates used for the conversion of the Consolidated Monthly Income Statements for the year 
ended 31 December 2022 was between 1.20-1.36 (2021: between 1.33-1.41). The closing $-GBP exchange rate used for the conversion of 
the Group’s assets and liabilities at 31 December 2022 was 1.21 (2021: 1.35). 

2. SIGNIFICANT ACCOUNTING POLICIES
2.1 Basis of preparation
The Group financial statements have been prepared in accordance with UK adopted international accounting standards and in conformity 
with the requirements of the Companies Act 2006. The Parent Company financial statements have been prepared in accordance with 
Financial Reporting Standard101 (‘FRS 101’) ‘Reduced Disclosure Framework’. 

2.2 Going Concern
The financial statements have been prepared on a going concern basis.

The Directors have prepared detailed income statement, balance sheet and cash flow projections for the period to 30 April 2024 (“going 
concern assessment period”). The cash flow projections have been subjected to sensitivity analysis of the revenue, cost and combined revenue 
and cost levels which demonstrate that the Group and Company will maintain a positive cash balance through the going concern assessment 
period. As part of the sensitivity analysis, the Directors have noted that should the forecasted revenues not be achieved, mitigating actions can 
be taken to address any cash flow concerns. These actions include the utilisation of the undrawn revolving credit facility of £1 million, deferral 
of capital expenditure, reduction in marketing and other variable expenditure alongside a hiring freeze. In addition, the projections confirm 
that the bank loan covenants will be met during the going concern assessment period.

The Directors are also not aware of any significant matters in the remainder of calendar 2024 that occur outside the going concern period 
that could reasonably possibly impact the going concern conclusion.

The Directors have also considered the geo-political environment, including rising inflation in some of our key markets and the conflict in 
Ukraine, and whilst the impact on the Group is currently deemed minimal, the Directors remain vigilant and ready to implement mitigation 
action in the event of a downturn in demand or an impact on operations.

On this basis, the Directors have therefore concluded that it is appropriate to prepare the financial statements on a going concern basis. 

2.3 Basis of consolidation
The consolidated financial statements incorporate the results, assets, liabilities, and cash flows of the Company and each of its subsidiaries 
for the financial year ended 31 December 2022. 

Subsidiaries are entities controlled by the Group. Control is deemed to exist when the Group has all of the following elements: a) power 
over the subsidiary, b) exposure or rights to variable returns from that subsidiary, and c) ability to use its power to affect the amount of the 
return from the subsidiary. The results, assets, liabilities and cash flows of subsidiaries are included in the consolidated financial statements 
from the date control commences until the date that control ceases.

Where necessary, adjustments are made to the financial statements of subsidiaries to bring the accounting policies used into line with 
those used by the Group.

Intra–group balances and transactions are eliminated on consolidation.

2. SIGNIFICANT ACCOUNTING POLICIES CONTINUED
2.4 Business combinations
The acquisition method is used to account for all acquisitions. The cost of an acquisition is measured at the fair values, on the date of 
acquisition, of assets given, liabilities incurred or assumed, and equity instruments issued. 

At the date of acquisition, the identifiable assets and liabilities and contingent liabilities of a subsidiary are measured at their fair values. 
Any excess of the cost of acquisition over the fair values of the identifiable net assets acquired is recognised as goodwill.

2.5 Revenue
The Group’s revenue is derived from the following products and services:

•  appliance and perpetual software licenses;

• 

• 

• 

software subscription licenses for a defined term;

support services for a defined term;

installation and training services;

•  DDoS Protection as-a-Service (‘DDPaaS’) for a defined term; and

•  SecureWatch Managed Service (enhanced security monitoring services) for a defined term.

The element of DDPaaS revenues pertaining to as-a-service assets is included in reported revenues and is recognised on a straight–line 
basis over the term of the contract.

Performance obligations, timing of revenue recognition and revenue recognition
Revenue is recognised when control of the goods (appliances and software) transfer to the customer and services are delivered.  
Goods are shipped free on board (‘FOB’) from Corero, or Corero’s contract manufacturer, to the customer. The point of transfer of control  
for appliances is at the point of FOB shipment to the customer and for software at the point of electronic transfer to the customer.

Revenue recognised on transfer of control of appliance 
and software products

Appliance, perpetual software licenses and software subscription licenses

Revenue recognised over–time (over the term of the contract)

Support, DDPaaS and SecureWatch Managed services

Revenue recognised once the service has been delivered

Installation and training services

Determining the transaction price
The contract price is determined by reference to the Corero Sales Quotation or DDPaaS Agreement and is a fixed price. Certain DDPaaS 
contracts have an element of the transaction value or all of the transaction value determined by reference to a share of the customers’ 
revenue generated from the Corero solution (‘Revenue Share’). This Revenue Share revenue is recognised when the Revenue Share 
is determined.

Corero does not have any other variable consideration payable by the customer and does not pay any consideration to the customer.  
There is no provision for purchase price adjustments, right of return or price concessions.

Allocating amounts to performance obligations
For contracts containing only a single performance obligation (annual support services, ‘DDPaaS’ and SecureWatch Managed Service) 
there is no requirement to make an allocation of the contract price. 

For contracts containing multiple products, the transaction price is allocated to the separate performance obligations based on relative 
stand–alone selling prices (‘SSP’). The SSP is determined using defined price lists and historic customer discount rates.

Strategic Report

FiNANCiAL STATeMeNTS

Incremental costs of obtaining a contract
Deferred sales commission relating to the support and DDPaaS revenue from a new sales contract is recorded in prepayments and 
amortised over five years. Corero follows the requirements of the IFRS 15 standard with regards to the amortisation period which requires 
amortisation on a systematic basis that is consistent with the transfer to the customer of the goods or services to which the asset relates. 
The expectation, supported by historic evidence, is that customers will generally renew their support contracts for more than three years 
with the additional expectation of follow–on hardware and software (and associated services) business from a significant number of existing 
customers. Based on this, and consistent with previous treatment, Corero has assessed that a reasonable period for capitalised sales 
commission to be amortised is five years. Periodic customer reviews will be undertaken to ascertain if there is any evidence that the value 
of the customer relationship has been negatively impacted, in which case the prepayment will be appropriately written down. Applying the 
practical expedient, Corero recognises the incremental costs of obtaining contracts as an expense when incurred if the amortisation period 
of the prepayment that Corero otherwise would have recognised is one year or less.

Fulfilment costs
Corero’s principal fulfilment costs relate to the costs of the Corero customer support team which delivers the customer support services, 
DDPaaS services and the SecureWatch Managed services. These costs are not separately allocated or identifiable against specific 
customers. Therefore, these costs are recognised in the period in which they are incurred in the Consolidated Income Statement.

Contract assets and liabilities
Contract assets arise when goods and services have been delivered and invoiced but payment is not yet due. Contract liabilities arise for 
future delivery of services which have been invoiced and payment is due. Contract liabilities are shown as deferred income in the Statement 
of Financial Position.

2.6 Government grants
Government grants are recognised at fair value when there is reasonable assurance that the Group will comply with the conditions 
attaching to them and the grant will be received. Grants related to purchase of assets are treated as deferred income and allocated to 
the Consolidated Income Statement over the useful lives of the related assets while grants related to expenses are netted off against the 
related item of expenditure in the Consolidated Income Statement. 

2.7 Cost of sales
Cost of sales includes all direct costs associated with revenue generation, including goods directly related to revenue, services delivery, 
operation costs, DDoS as-a-service depreciation and amounts charged by external third parties for services. Examples of such costs would 
include third–party appliance costs and third-party software license costs.

2.8 Foreign currencies
Transactions in foreign currencies are translated at the exchange rate ruling at the date of each transaction. Foreign currency monetary 
assets and liabilities are retranslated using the exchange rates at the reporting date. Gains and losses arising from changes in exchange 
rates after the date of the transaction are recognised in profit or loss in the Consolidated Income Statement. 

Non–monetary assets and liabilities that are measured in terms of historical cost in a foreign currency are translated at the exchange rate at 
the date of the original transaction.

In the consolidated financial statements, the net assets of the Group’s UK operations are translated from GBP into US dollars at the 
exchange rate at the reporting date. Income and expense items are translated into US dollars at the average exchange rates for the period. 
The resulting exchange differences are recognised in the foreign exchange translation reserve.

2. SIGNIFICANT ACCOUNTING POLICIES CONTINUED
2.9 Intangible assets
Internally generated intangible assets
The Group’s internally generated intangible asset relates to its development expenditure.

Development expenditure is capitalised only when it is probable that future economic benefit will result from the project and the following 
criteria are met:

• 

the technical feasibility of the product has been ascertained;

•  adequate technical, financial and other resources are available to complete and sell or use the intangible asset;

• 

• 

• 

the Group can demonstrate how the intangible asset will generate future economic benefits and the ability to use or sell the intangible 
asset can be demonstrated;

it is the intention of management to complete the intangible asset and use it or sell it; and 

the development costs can be measured reliably.

Expenditure not meeting these criteria is expensed in the Consolidated Income Statement.

After initial recognition, internally generated intangible assets are carried at cost less accumulated amortisation and any impairment losses. 
Amortisation is charged once the asset is capable of generating economic benefits. 

Acquired intangible assets
Identifiable intangible assets acquired as part of a business combination are initially recognised separately from goodwill, irrespective of 
whether the assets have been recognised by the acquiree before the business combination. An intangible asset is considered identifiable 
only if it is separable or if it arises from contractual or other legal rights, regardless of whether those rights are transferable or separable 
from the entity or from other rights and obligations.

Intangible assets acquired as part of a business combination and recognised by the Group are computer software and 
customer relationships. 

Purchased computer software is carried at cost less accumulated amortisation and any impairment losses.

Customer contracts and the related customer relationships are carried at cost less accumulated amortisation and any impairment losses.

Amortisation
Intangible assets are amortised on a straight–line basis to reduce their carrying value to zero over their estimated useful lives. The following 
useful lives were applied during the year:

•  Computer software acquired – three years straight line.

•  Capitalised development expenditure – five years straight line.

Amortisation costs are included within operating expenses in the Consolidated Income Statement. Methods of amortisation and useful 
lives are reviewed, and if necessary adjusted, at each reporting date.

2.10 Property, plant and equipment
Depreciation commences when an asset is available for use. Depreciation is calculated so as to write off the cost or value of an asset, net of 
anticipated disposal proceeds, over the useful life of that asset as follows:

• 

Leasehold improvements – period of the lease (straight-line basis).

•  Right-of-use assets – period of the lease (straight-line basis).

•  Computer equipment, evaluation assets and DDoS Protection as-a-Service assets – three years (straight-line basis).

•  Fixtures and fittings – five years (straight-line basis).

Property, plant and equipment is stated at cost less accumulated depreciation and any impairment losses. Cost comprises the purchase 
cost of property, plant and equipment together with any directly attributable costs. Evaluation assets are used by customers during proof-
of-concept trials. Evaluation assets are stated at cost less accumulated depreciation. When an evaluation asset is retained by a customer as 
part of a sale, the net book value of the evaluation asset is charged to cost of sales. Depreciation of DDoS Protection as-a-Service assets is 
charged to cost of sales.

Subsequent costs are included in an asset carrying value or are recognised as a separate asset when it is probable that future economic 
benefits associated with the additional expenditure will flow to the Group and the cost of the item can be measured reliably. All other costs 
are charged to the Consolidated Income Statement as incurred.

Methods of depreciation, residual values and useful lives are reviewed, and if necessary adjusted, at each balance sheet date.

The gain or loss arising from the disposal or retirement of an item of property, plant and equipment is determined as the difference 
between the net disposal proceeds and the carrying amount of the item and included in the Consolidated Income Statement. 

2.11 Inventory
Inventory is stated at the lower of cost or net realisable value. Cost is computed using standard cost, which approximates to actual cost, on 
a first-in, first-out basis. Rapid technological change and new product introductions and enhancements could result in excess or obsolete 
inventory, the value of which may not be recoverable. 

To minimise this risk, the Group evaluates inventory levels and expected usage on a periodic basis and records valuation allowances 
as required.

2.12 Impairment
At each reporting date, the Group assesses whether there is any indication that its assets have been impaired. If any such indication exists, 
the recoverable amount of the asset is estimated in order to determine the extent of any impairment. If it is not possible to estimate 
the recoverable amount of the individual asset, the recoverable amount of the cash-generating unit (‘CGU’) to which the asset belongs 
is determined.

The recoverable amount of an asset or a CGU is the higher of its fair value less costs to sell and its value in use. The recoverable amount 
is calculated using the present value of the future cash flows expected to be derived from an asset or CGU. This present value is derived 
using a cost of capital rate that reflects current market assessments of the time value of money and of the risks specific to the asset for 
which future cash flow estimates have not been adjusted. If the recoverable amount of an asset is less than its carrying amount, the carrying 
amount of the asset or CGU is reduced to its recoverable amount. That reduction is recognised as an impairment loss.

An impairment loss relating to assets carried at cost less any accumulated depreciation or amortisation is recognised immediately in the 
Consolidated Income Statement.

Goodwill acquired in a business combination is, from the acquisition date, allocated to each of the CGU’s or groups of CGU’s that are 
expected to benefit from the synergies of the combination.

Goodwill is tested for impairment at least annually, and whenever there is an indication that the asset may be impaired.

An impairment loss is recognised for CGU’s if the recoverable amount of the CGU is less than the carrying amount of the CGU. The impairment 
loss is allocated to reduce the carrying amount of the assets of the CGU by first reducing the carrying amount of any goodwill allocated to the 
CGU, and then reducing the carrying amounts of the other assets of the CGU pro rata.

If an impairment loss subsequently reverses, the carrying amount of the asset or CGU is increased to the revised estimate of its recoverable 
amount but limited to the carrying amount that would have been determined had no impairment loss been recognised in prior years. 

A reversal of an impairment loss is recognised in the Consolidated Income Statement. Impairment losses on goodwill are not 
subsequently reversed.

2.13 Leases
All leases are accounted for by recognising a right-of-use asset and a lease liability except for:

• 

• 

leases with a duration of 12 months or less; and

leases of low value assets.

Lease liabilities are measured at the present value of the contractual payments due to the lessor over the lease term, with the discount 
rate determined by reference to the rate inherent in the lease unless this is not readily determinable, in which case the Group’s incremental 
borrowing rate on commencement of the lease is used.

2. SIGNIFICANT ACCOUNTING POLICIES CONTINUED
2.13 Leases continued
On initial recognition, the carrying value of the lease liability also includes:

•  amounts expected to be payable under any residual value guarantee; 

• 

the exercise price of any purchase option granted in favour of the Group if it is reasonably certain to assess that option; and

•  any penalties payable for terminating the lease, if the term of the lease has been estimated on the basis of termination option 

being exercised.

Right-of-use assets are initially measured at the amount of the lease liability, reduced for any lease incentives received, and increased for:

• 

• 

• 

lease payments made at or before commencement of the lease;

initial direct costs incurred; and

the amount of any provision recognised where the Group is contractually required to dismantle, remove or restore the lease.

Subsequent to initial measurement, lease liabilities increase as a result of interest charged at a constant rate on the balance outstanding 
and are reduced for lease payments made. Lease payments are analysed between capital and interest. The interest element is charged to 
the Consolidated Income Statement over the period of the lease. The capital element reduces the balance owed to the lessor.

Right-of-use assets are amortised on a straight-line basis over the remaining term of the lease or over the remaining economic life of 
the asset.

The total rentals payable under leases which are not recognised as a right-of-use asset and a lease liability (an ‘operating lease’) are 
charged to the Consolidated Income Statement on a straight-line basis over the lease term.

2.14 Investments in subsidiaries
In the Company’s separate financial statements, investments in subsidiaries are carried at cost less any impairment provisions.

2.15 Taxation
The tax expense represents the sum of current tax and deferred tax.

Current tax
Current tax is based on taxable profit for the year and is calculated using tax rates enacted or substantively enacted at the reporting date. 
Taxable profit differs from accounting profit either because items are taxable or deductible in periods different to those in which they are 
recognised in the financial statements (temporary differences), or because they are never taxable or deductible (permanent differences). 

Deferred tax
Deferred tax on temporary differences at the reporting date between the tax bases of assets and liabilities and their carrying amounts for 
financial reporting purposes is accounted for using the balance sheet liability method.

Using the balance sheet liability method, deferred tax liabilities are recognised in full for all taxable temporary differences and deferred tax 
assets are recognised to the extent that it is probable that taxable profits will be available against which deductible temporary differences 
can be utilised. However, if the temporary difference arises from the initial recognition of goodwill or the initial recognition of an asset or 
liability in a transaction other than a business combination, that at the time of the transaction affects neither accounting nor taxable profit, 
it is not recognised as deferred tax asset or liability.

Deferred taxation is measured at the tax rates that are expected to apply when the asset is realised, or the liability settled, based on tax 
rates and laws enacted or substantively enacted at the reporting date. 

2.16 Post-retirement benefits
The Group makes contributions in respect of certain employees to defined contribution pension plans under which it is required to pay 
fixed contributions to group and personal pension funds. 

Contributions to the schemes are based on a proportion of the employees’ earnings and are charged to the Consolidated Income 
Statement. The Group has no obligation beyond these contributions.

2.17 Financial instruments
The Group classifies financial instruments, or their component parts, on initial recognition as a financial asset, a financial liability, or an 
equity instrument in accordance with the substance of the contractual arrangement.

Financial assets and financial liabilities are recognised in the Group’s Statement of Financial Position when the Group becomes party to the 
contractual provisions of the instrument.

The particular recognition and measurement methods adopted for the Group’s financial instruments are disclosed below:

Trade and other receivables
Trade and other receivables are stated at their fair value at time of initial recognition, reflecting, where material, the time value of money. 
A provision for impairment of trade receivables is established when there is evidence that the Group will not be able to collect all amounts 
due. The simplified approach is used for assessing the expected credit loss on trade receivables, requiring the lifetime expected credit loss 
to be recorded as the provision for impairment. 

An impairment provision is recorded against the intercompany loan note instrument between the Company and Corero Network Security, 
Inc. based on calculating the risk adjusted carrying value of the loan to take account of the credit loss which is expected to arise over the 
period until the cash is realised. The amount of the provision is based on whether there has been a significant increase in credit risk since 
the initial recognition of the loan. In situations where the credit risk has not increased significantly and the loan amount is expected to be 
recovered, the expected credit loss is limited to the effect of discounting the intercompany loan over the period until repayment is realised 
at the effective interest rate. 

Cash and cash equivalents
Cash and cash equivalents include cash in hand and deposits on call with banks.

Trade and other payables
Trade and other payables are not interest bearing and are stated at their fair value at time of initial recognition. Thereafter they are 
accounted for at amortised cost.

Debt obligations
Debt obligations include interest bearing bank borrowings which are stated at their fair value less transaction costs at time of initial 
recognition. Debt obligations are subsequently measured at amortised cost.

2.18 Equity instruments
An equity instrument is any contract that evidences a residual interest in the assets of the Company after deducting all its liabilities.  
Equity instruments issued by the Company are recorded at the proceeds received, net of directly attributable issue costs.

2.19 Employee share option schemes
The Group operates an equity-settled share-based compensation plan. The fair value of the employees’ services received in exchange for 
the grant of share options is measured at grant date and recognised as an expense on a straight-line basis over the vesting period, based 
on the Group’s estimate of shares that will eventually vest. Fair value is determined by reference to the Black-Scholes option pricing model. 
If a granted option is cancelled and regranted the increase in fair value of the granted option measured immediately before and after the 
cancellation and regrant is added to the value of the employee’s service received in exchange for the grant. If an option grant is cancelled 
the previously recorded expense is credited to the Consolidated Income Statement.

At each reporting date, the Group revises its estimate of the number of options that are expected to become exercisable. 

When share options are exercised, the proceeds received, net of any transaction costs, are credited to share capital (nominal value) and 
share premium. 

2.20 Standards and Interpretations not yet effective
There are a number of standards, amendments to standards, and interpretations which have been issued that are effective in future 
accounting periods that the Group has decided not to adopt early as they will not have a significant impact on the presentation of the 
Group financial statements.

3. CRITICAL ACCOUNTING JUDGEMENTS AND KEY SOURCES OF ESTIMATION UNCERTAINTY
3.1 Critical judgements in applying the Group’s accounting policies
In the process of applying the Group accounting policies, the following judgements have had a significant effect on the amounts 
recognised in the financial statements:

Internally generated research and development costs
Management monitors progress of internal research and development projects. Judgement is required in distinguishing the research  
phase from the development phase. Development costs are recognised as an asset when all criteria are met and a project has passed  
the feasibility phase, whereas research costs are expensed as incurred. Management monitors whether the recognition requirements  
for development costs continue to be met. This is necessary as the economic success of any product development is uncertain.

Going concern
The Directors have reviewed the future profit and cash flow projections in conjunction with the current economic climate in order to express 
an opinion on the adequacy of working capital and the ability to continue as a going concern for the foreseeable future. The methodology 
contained in the projections is detailed in the note 2.2.

3.2 Key accounting estimates and assumptions
Key assumptions concerning the future and other key sources of estimation uncertainty that have a significant risk of causing a material 
adjustment to the carrying amounts of assets and liabilities within the next financial year are as follows:

Impairment of intangible assets and property, plant and equipment
The Group tests goodwill at least annually for impairment, and whenever there is an indication that the asset may be impaired. All 
other intangible assets and property, plant and equipment are tested for impairment when indicators of impairment exist. Impairment 
is determined with reference to the higher of fair value less costs to sell and value in use. Fair value less costs to sell is estimated using 
discounted future cash flows. Significant assumptions are made in estimating future cash flows about future events including future market 
conditions, future growth rates and appropriate discount rates. Changes in these assumptions could affect the outcome of impairment 
reviews. Details of the main assumptions used in the assessment of the carrying value of the Group’s CGU are set out in note 9.

Impairment of investments (applies to the Company financial statements only)
The Directors have reviewed the cost of investments in subsidiaries of the Company with reference to current and future trading conditions. 
The investment in subsidiaries has been reviewed with reference to a valuation based on a discounted free cash flow, in conjunction with 
the goodwill impairment review, which the Directors consider to be an appropriate valuation methodology. 

Standalone Selling Price – Revenue recognition
On a quarterly basis the Group analyses the selling prices for each deal compared to the current Standalone Selling Price (‘SSP’). This 
analysis includes grouping similar deals based on qualitative factors such as customer profile, size, and region, together with a quantitative 
comparison to the then current SSP. SSP fair value prices are adjusted for future quarters if management identifies a pattern of variances of 
greater than 10% between actual selling prices and the then current SSP.

Factors affecting future tax charges
As at 31 December 2022, the Group’s cumulative fixed asset timing differences were $12,000 (2021: $23,000) and no deferred tax asset has 
been recognised in respect of these items.

Tax losses at 31 December 2022 amounted to $89.7 million (2021: $89.3 million). This comprised UK tax losses of $13.5 million and US tax 
losses of $76.2 million. The utilisation of US tax losses which are all attributable to Corero Network Security, Inc. is subject to the provisions 
of Section 382 of the United States Treasury Internal Revenue Code of 1986, as amended. Corero Network Security, Inc did not undergo an 
ownership change within the meaning of section 382 for the period 1 February 2017 to 31 December 2021, and thus $15.0 million of the US 
tax losses are available at full value to set-off against future taxable profits. The utilisation of the remaining US tax losses of $61.2 million will 
be subject to meeting the change of ownership test for the period prior to 1 February 2017. This test will be undertaken as and when these 
tax losses are required to offset against taxable profits of Corero Network Security, Inc. US tax losses expire 20 years from the end of the 
accounting period in which the loss arose.

UK tax losses arising in the period prior to 1 April 2017 can only used against taxable profits of the same trade, after 1 April 2017 the losses 
can be used against total company profits.

Deferred tax assets of $3.4 million (2021: $3.4 million) relating to the UK tax losses (applying a tax rate of 25.0% to tax losses expected to 
unwind after 1 April 2023, the rate substantively enacted on 10 June 2021) and the deferred tax assets of $16.0 million (2021: $15.9 million) 
relating to the US tax losses and taxable temporary fixed asset differences (applying a tax rate of 21.0%) have not been recognised due to 
uncertainties as to the extent and timing of their future recovery.

7. EARNINGS PER SHARE
Earnings per share is calculated by dividing the earnings attributable to ordinary shareholders of the Company by the weighted average 
number of ordinary shares in issue during the year. Diluted earnings per share is calculated by dividing the earnings attributable to ordinary 
shareholders of the Company by the weighted average number of ordinary shares in issue during the year plus the number of ordinary 
shares to be issued from the exercise of attributable share options.

Goodwill is tested at least annually for impairment and when there are indications that goodwill might be impaired.

Goodwill is allocated to the Group’s single CGU, Corero Network Security (‘CNS’).

The recoverable amount for the CNS CGU was determined based on a discounted cash flow calculation to calculate fair values less costs 
to sell using cash flow projections over a 10 year period (2021: 10 year period). The discounted cash flow approach is a level 3 fair value 
calculation in the IFRS 13 fair value hierarchy. 

The key assumptions for the discounted cash flow calculation are those regarding revenue growth and discount rates as summarised in the 
table below and commented on below:

The pre-tax cash flows for the forecast period are derived from the most recent financial budget for the year ending 31 December 2023 
(‘2023 Budget’) and the plan for the year ending 31 December 2024 (‘2024 Plan’) approved by the Board, with a sensitivity reflecting  
prior year experience and progress made in 2022 (10% applied to the 2023 Budget revenue and 15% to the 2024 Plan revenue).  
The extrapolation for the period 2025 to 2032 is based on management estimates (with the key assumptions set out below).

The future pre-tax cash flows are discounted by a WACC of 17.3% (2022: 12.3%).

The key assumptions underlying the cash flow projections and which the recoverable amount is most sensitive to are (i) the revenue growth 
rates forecast and extrapolated for the period 2023 to 2027 (ii) and the discount rate.

The cash flow forecasts assume a CAGR revenue growth of 15.5% in the period 2023 to 2027 (18.3% for the period 2022 to 2026) and 
6.5% for the period 2028 to 2032 (a ‘CAGR’ of 10.9% for 10-year forecast period; 2022: 12.2%). The cashflow forecasts reflect a sensitivity 
of 10% applied to the CNS 2023 Budget revenues and a sensitivity of 15% applied to the 2024 Plan revenues (and a sensitivity of 5% to 
2023 operating costs and capital expenditure, and a sensitivity of 7.5% to 2024 operating costs and capital expenditure) reflecting prior 
year experience. The management of the Group believe these growth rates are appropriate for the forecasts given the significant progress 
the business made in 2021 and 2022, the strategy for 2023 which is focused on scaling the business for profitability through leveraging 
the Group’s expanded routes to market and the on-going investment in sales and marketing. This strategy is expected to deliver further 
increases in revenue in the forecast period. 

The assumed growth rates are supported by the fact that the IT security market is forecast to grow strongly for the foreseeable future. 
The DDoS market is expected to reach $6.7 billion by 2026 (Source: MarketsandMarkets DDoS Protection and Mitigation market – Global 
Forecast to 2026, June 2019) – a CAGR of 15.1% in the period 2021 to 2026. 

The above market growth rates used in the future cash flow assumptions reflect that CNS is in the relatively early stages of the commercial 
exploitation of its intellectual property. In addition, the business’s strategy, aside from greater sales growth penetration, is to continue to 
develop its product and solution offerings to remain its market leadership technological credentials in its chosen markets thereby providing 
the opportunity to generate above market average growth rates. 

The growth rate assumed in the period beyond the 10-year extrapolation period of 2.5% is considered reasonable as historically IT spend 
has exceeded GDP growth.

9. GOODWILL CONTINUED
The discount rate is based on a cost of equity using the Capital Asset Pricing Model with the key inputs being a risk-free interest rate 
estimate of 3.88% (based on 10-year US government bonds) (2021: 1.52%), comparable company betas, an equity risk premium of 6.2% 
(2021: 6.2%), and small company risk premium of 4.5% (2021: 4.5%). The WACC has been assessed based on that fact that the Company 
had debt at 31 December 2022 of $1.2 million (debt at 31 December 2021: $2.8 million). The WACC used in the valuation reflects current 
market assessments of the time value of money and the risks specific to CNS.

As stated above, the valuation to support the value in use of the CNS CGU is sensitive to changes in the cash flow forecasts and the 
discount rate assumptions, and there is no absolute guarantee that the expected growth will be achieved. If the discount rate is increased 
from 17.3% to 48.0%, this would mathematically result in an impairment of the carrying value of goodwill of $9 million meaning the goodwill 
would be fully impaired. If the sensitivity of 10% applied to the CNS 2023 Budget and 15% to the 2024 Plan revenues (and sensitivity of 
5% to CNS 2023 Budget operating costs and capital expenditure, and 7.5% to the 2024 Plan operating costs and capital expenditure) was 
increased to 34.0% for the CNS 2023 Budget and 36.0% to the 2024 Plan revenues (and sensitivity of 17.0% to CNS 2023 Budget operating 
costs and capital expenditure, and 18.0% to the 2024 Plan operating costs and capital expenditure), this would mathematically result in an 
impairment of the carrying value of goodwill of $9 million meaning the goodwill would be fully impaired. 

Apart from the considerations in determining the value in use of the CNS CGU extensively described above, the management of the Group 
is not currently aware of any other reasonably possible changes that would necessitate changes in its key estimates.

None of the Company’s trade and other receivables are secured by collateral or credit enhancements (2021: None).

The Group applies the simplified approach to measuring expected credit losses using a lifetime expected credit loss for trade receivables 
and contract assets. To measure expected credit losses on a collective basis, trade receivables and contract assets are grouped based on a 
similar credit risk and aging. The expected loss rates are based on the Group’s historical credit losses experienced over a two year period 
prior to the period end. The historical loss rates are then adjusted for current and forward-looking information on macroeconomic factors 
affecting the Group’s customers. The Group has identified gross domestic product growth rates, unemployment rates and inflation rates as 
the key macroeconomic factors in the countries in which the Group operates. The Directors consider that the carrying amount of trade and 
other receivables approximates their fair value.

a guarantee from the Company. The bank loan terms include typical covenants for such a loan, as well as revenue and cash consumption 
covenants, which are tested quarterly and monthly respectively. These covenants were met for each covenant reporting period in the

The Company’s US trading subsidiary, Corero Network Security, Inc was advanced, via its US bank, Pacific Western Bank, a Paycheck 
Protection Program Loan for $637,000 on 11 May 2020. The PPPL was a component of the US federal stimulus package known as the 
Coronavirus Aid, Relief and Economic Security Act, which offered help to businesses in the US during the COVID-19 crisis. Notification of 
the PPP loan forgiveness in full was received from Pacific Western Bank on 28th January 2021. The forgiveness of the PPP loan is a non–cash

27. SHARE OPTIONS 
The Company has the following share option schemes:

•  Enterprise Management Incentive Scheme for its employees, which has been approved by HMRC.

•  Executive Enterprise Management Incentive Scheme, which has been approved by HMRC.

•  Unapproved Share Option Scheme.

•  Deferred Payment Share Plan.

Options granted have a three–year vesting period, vesting one third on the first anniversary of grant, one third on the second anniversary 
of grant and one third on the third anniversary of grant. Shares acquired on the exercise of an option may not be sold until the expiry of 
the second anniversary following the date of option grant. With the exception of options granted in April 2017 to Directors which include a 
revenue growth performance vesting condition, there are no vesting conditions for options granted.

If an option holder ceases to be in employment or hold office within the Group, options granted shall immediately lapse unless such 
cessation is because of the option holder’s death; the option holder’s ill health or disability; the company that employs the option holder 
ceasing to be under the control of the Company or such company ceasing to be within the Group; the transfer of sale of the undertaking 
or part-undertaking in which the option holder is employed to a person who is neither under the control of the Company nor within the 
Group; or any other reason that the Board in its absolute discretion shall determine.

On a cessation of employment or office as set out above, options shall be exercisable to the extent they have vested according to the 
terms of the option agreement and the provisions of the relevant share option scheme and must be exercised within 30 days following such 
cessation unless otherwise determined by the Board or if such cessation is by reason of death in which case the option holder’s personal 
representatives must exercise the option within 12 months following the date of the option holder’s death.

For option agreements granted post June 2020 and subject to the approval of the Board, where an option holder has, as at the date of 
the grant, been employed by a Group company for a period of at least three years and whose employment is terminated either: (a) by 
the company other than for cause; or (b) by resignation on the part of the option holder, such option holder shall be entitled to retain the 
options granted under the option agreement following the effective date of the termination and such retained options shall continue to 
vest and be exercisable by the option holder in accordance with the vesting terms set out in the agreement.

Share options granted at 31 December 2022 were as follows:

Share-based payments

option schemes. 

Share options are granted with a fixed exercise price which is equal to the market price at the date of the grant or higher price determined 
by the RC. The share options granted are required to be exercised within 10 years from the date of grant. 

Share options are valued using the Black-Scholes option-pricing model.

The weighted average fair value of the options granted in the year was 6.9p (7.82c). The value of share options granted during the year was 
calculated using the Black-Scholes option pricing model. The following variables and ranges were used:
