STRATEGIC REPORT

What  
we do

The Corero First Line of Defense 
products and services stop DDoS 
attacks and cyber threats

OUR TECHNOLOGY

A high performance network appliance which is deployed on premises (at the customer or managed location) or in service provider 
networks. The appliance inspects Internet traffic in real time before it is allowed to pass into the customers protected IT environment  
to ensure unwanted and malicious Internet traffic is removed.

•    The Corero Patented 
Dynamic Threat 
Assessment technology 
uses several algorithms 
including advanced 
challenge-response 
techniques to categorise  
all sources as unknown, 
trusted, suspicious or 
malicious based upon  
their real-time behaviours.

•    The Corero Request/
Response Behaviour 
Analysis controls access  
to downstream devices 
based upon a source’s 
“behaviours” which 
enables enforcement of 
usage standards on every 
source IP address which 
provides detection of 
application-layer denial  
of service attacks, as  
well as other unwanted 
behaviours and blocks 
them before they reach 
the victim devices.

•    The Corero Protocol 

Validation Engines inspects 
all packets of a network 
and/or application 
transaction and compares 
the observed content and 
characteristics to what is 
allowed, expected, or 
required, based upon the 
protocol specifications and 
known implementations, 
and takes the appropriate 
real time actions (e.g. 
detection/blocking) of  
the violations.

•    Corero has a real-time 
reputation engine, 
ReputationWatch, that 
provides automated 
real-time defence against 
previously identified DDoS 
attack sources. In addition, 
IP address geolocation 
technology enables 
enforcement of security 
policies based on national 
origin of IP addresses.

OUR SERVICES

Threat 
Update

Reputation 
Watch

An automated protection update service that provides Corero customers with timely, 
proactive protection from the latest security threats. The subscription service delivers 
frequent protection updates and security advisories. These updates include updated 
vulnerability and attack signatures to provide the most current, effective network threat 
monitoring. Security advisories, an important aspect of the Threat Update Service, 
inform customers of newly discovered threats, and recommend any actions that might  
be necessary to obtain protection against the threat.

Enables customers to automatically block malicious IP addresses. Corero continuously 
receives data feeds from global intelligence across the Internet to determine the current 
threat status of malicious or suspicious IP addresses. Using IP reputation-based 
information, ReputationWatch automatically identifies and blocks access from suspicious 
sites including sources that have participated in DDoS attacks, systems delivering 
specially crafted denial-of-service exploits, anonymized IP addresses behind proxies, 
phishing sites, and spam sources. ReputationWatch also allows customers to block or 
alert on access from countries with which they do not transact business for example by 
choosing to block or set rate limits on all traffic from a nation or geography. 

SecureWatch

A service which ensures that customers’ First Line of Defense solutions are always  
up to date, running at optimum performance, and continuously protecting customers’  
IT infrastructure against the latest threats.

SecureWatch 
Plus

A comprehensive suite of DDoS defence configuration, optimization, 24x7 monitoring  
and attack mitigation services. These services are customised to meet the security 
requirements and business goals of each customer. SecureWatch PLUS includes access 
to experts to assist in the realisation of the desired DDoS defence solution starting with 
the organisation-specific implementation, commissioning and testing, continuing with 
round-the-clock monitoring, and immediate response in the event of a DDoS attack.

Corero is dedicated to improving the 
security of the Internet through the 
deployment of its innovative First Line 
of Defense solutions which provide 
customers with protection against a 
continuously evolving spectrum of 
DDoS attacks and cyber threats that 
have the potential to impact any Internet 
connected business.

The Internet has transformed the way commercial and public sector 
organisations do business
Organisations today are embracing technology to enhance the productivity of their 
employees, generate new revenue sources and improve their operating efficiency.  
These technologies include cloud services, mobile computing, online services and  
social networking. This greater reliance on information technology has significantly 
increased the attack surface within organisations that is vulnerable to potential security 
attacks. As a result organisations are having to make significant investments in IT 
security to help protect against a myriad of potential threats. 

The threat landscape has evolved

“Cyber attacks are one of the top four threats to our national security and cyber-crime  
is costing our economy billions of pounds a year. And as businesses and government 
move more of their operations online, the scope of potential targets will continue to  
grow. It’s a race: to build sufficient cyber defences to match the growing volume and 
dependence of our online economic, security and social interests.” 

UK Cabinet Office Minister, Francis Maude

Cyber-crime continues to be costly

•    The average annualised cost of cyber-crime for organisations is $11.6 million  

per year (an increase of 26% over 2012)

•    Cyber attacks have become common occurrences – two successful attacks  

per company per week (an increase of 18% over 2012)

•    The most costly cyber-crimes are those caused by DDoS, malicious insiders  

and web-based attacks

Source: Ponemon Institute 2013 Cost of Cyber Crime Study

Existing security solutions do not protect against next-generation threats
Though firewalls are still a critical and necessary component of any IT network, they  
are no longer the best type of device to deploy as the network’s first line of defence. 
While firewalls serve many purposes, they do not have complete Layer 3–7 protection. 
Attackers know these limitations and have devised attacks that can evade or overwhelm 
a firewall, as well as the secondary security devices behind the firewall, such as intrusion 
prevention systems. 

The opportunity for Corero
Organisations need to respond to the increased risk presented by the growing number 
of DDoS attacks and cyber threats – a security device specifically designed to detect  
and stop unwanted traffic before it can overrun the IT infrastructure causing performance 
issues, security exposures and even catastrophic outages.

This new first line of defence must be able to identify malicious attack traffic even if it 
mimics legitimate traffic and the true customer communications that businesses want 
and welcome.

The Corero First Line of Defense solution applies industry best practices as well as 
sophisticated analysis techniques to thoroughly inspect traffic in order to stop DDoS 
attacks and cyber threats. The Corero solution stops unwanted traffic that slows the 
infrastructure and frustrates users, and in the process protects the existing infrastructure 
and enables maximum uptime of business applications.

THE COMPETITIVE ENVIRONMENT

Corero is a leader in protecting enterprises and public sector 
organisations against DDoS attacks and cyber threats. We have 
defined the market for on premises First Line of Defense and  
have developed the following key competitive advantages that  
we believe will allow us to extend our leadership position:
•    Always-on protection that blocks both network-layer flooding 
attacks, as well as the more difficult to detect, low and slow 
application-layer attacks.

•    Granular configuration of security policies in order to allow 
legitimate traffic to pass while blocking unwanted traffic.

•    Broad security coverage – Inspection of every packet and  
every flow (using Deep Packet Inspection) rather that a 
sample-based approach used by most competitors. 

•    Purpose-built security appliance for high speed traffic 
inspection using a multi-core processor architecture.

•    Competitive price-performance resulting in the lowest total 

cost of ownership for the end user.

•    Expert security knowledge and technical support provided  

by Corero’s 24x7 Security Operations Centre.

Our next generation product, SmartWall TDS, was launched  
on 3 February 2014 to address the Internet service provider and 
hosting provider markets. It adds key features like asymmetric 
inspection, and multi-tenancy to allow our First Line of Defense 
solutions to be deployed in service provider networks and hosting 
data centers as a services-oriented platform. Service providers 
and hosting providers can now deploy this platform in a modular 
and scalable fashion to not only protect their own infrastructure but 
more importantly to roll out revenue generating DDoS protection 
services to multiple customers. SmartWall TDS extends our current 
competitive advantages with the following key features:

OPPORTUNITIES

The awareness of cyber-crime and the impact on businesses 
(small and large) is increasing with Board room accountability and 
regulatory focus in certain industries, such as financial services. 
We expect this trend to have a positive impact on our market.
Ernst & Young’s Global information Security Survey 2013 reported  
that 50% of respondents indicate that their budgets will increase 
anywhere from 5% to 25% or more in the next 12 months, and  
14% of spend in the coming 12 months will be on security 
innovation (emerging technology).

KEY MARKET CHALLENGES

•    Robust security coverage – comprehensive network  

security protection against layer 3 and layer 4 for both  
IPv4 and IPv6 traffic.

•    Industry-leading density, scalability and performance 

– protection is provided through configurable access policies 
with scalability from 10Gbps to 1Tbps in a single rack.

•    Green, energy-efficient platform – energy-efficient design  
with front-to-back cooling which fully supports economic  
and environmental initiatives.

•    Powerful centralised management for configuring,  

controlling, and monitoring all SmartWall TDS appliances  
from a central location.

•    Flexible deployment configurations – multiple appliances  
can be distributed to key control points in the provider 
network or centrally combined in 1 Rack Unit shelves in 
various configurations.

•    Single solution to deliver comprehensive threat protection, 
always-on connectivity, and complete visibility with the  
family of SmartWall appliances.

The Corero principal competitors are other DDoS defence 
equipment manufacturers such as Arbor Networks Inc.  
and Radware Limited.

Corero is targeting a high growth security market; the DDoS 
market is forecast to grow by 18% (CAGR) in the period 2012  
to 2017 (Source: IDC) to $870 million. The existing Corero  
DDS product is targeted at the enterprise on premises DDoS 
protection market. The new SmartWall™ TDS product is  
targeted at the service provider and hosting provider market.

The market for security products and services is competitive and 
characterised by rapid changes in technology, the evolving cyber 
threat landscape, customer requirements, and industry standards 
and frequent new product introductions and improvements. We 
need to be focused on our chosen market and deliver continuous 

innovation to stay ahead of our competition. Corero will  
address this challenge by working closely with our customers  
and prospects, to leverage the flexibility of our platform 
technology to deliver continuously evolving leadership  
protection against the latest DDoS attacks and cyber threats.

Today’s enterprises are increasingly 
dependent on their online presence for 
generating revenues, ensuring employee 
productivity, or providing a superb 
customer experience. Ubiquitous Internet 
access makes the enterprise susceptible 
to cyber threats from around the world. 
The resulting service outages cause 
costly downtime, lost productivity, brand 
damage and impact the enterprise’s 
legitimate users.

The Corero DDoS Defense System 
(“DDS”) product family is targeted at 
enterprise and public sector organisations 
and is an organisation’s First Line of 
Defense against damaging DDoS attacks, 
delivering the most comprehensive DDoS 
protection available in a purpose-built, 
high performance, on-premises appliance. 
DDS detects and blocks both familiar 

network-layer flooding attacks, as well as 
the more difficult to detect, low and slow 
application-layer attacks, which have 
become the stealth attackers’ weapon  
of choice.

The Corero DDS uses an always on, 
adaptive, patented DDoS defence 
algorithms to ensure online businesses 

are always protected keeping services up 
and available – blocking malicious 
incoming requests while reliably passing 
legitimate traffic to the organisations’ 
online servers. Positioned at the Internet 
gateway, Corero’s next generation 
SmartWall TDS, which was launched on 3 
February 2014, is targeted at the following 
additional markets:

Internet Service Providers and 
Multi-Service Operators (MSOs)

Hosting companies offering  
Web, Cloud, Platform and 
Infrastructure-as-a-Service

Companies providing managed 
security services

The first customer deployments of SmartWall TDS are expected to be in the second half of 2014. 

The SmartWall TDS is a flexible and 
scalable cyber threat defence solution. 
SmartWall TDS is designed to enable 
Internet service providers and hosting 
providers the ability to offer comprehensive 
DDoS and cyber threat protection to their 
customers as an extension of their current 
value added service offerings, improving 
their overall value proposition and providing 
an opportunity to differentiate themselves 
from the competition. 

The family of SmartWall TDS appliances 
include:

•  SmartWall Network Threat Defense 

Appliance for comprehensive 
protection against network threats.

•  SmartWall Application Threat Defense 

Appliance for comprehensive 
protection against application threats.

•  SmartWall Network Bypass Appliance 
for 100% network connectivity to 
eliminate network downtime. 

•  SmartWall Network Forensics 

Appliance for capturing and indexing 
100% of the packets at 10Gbps rates 
for and complete visibility and 
forensics analysis.

The SmartWall TDS product launch follows 
an 18 month development project with 
directly attributable costs of $5.1 million (of 
which $3.8 million has been capitalised, 
$3.2 million capitalised in the year ended 
31 December 2013). 

The SmartWall TDS development will 
continue in 2014 and 2015 with further 
software releases planned to add new 
software functionality and features.

Corero has developed a high performance 
network appliance, a combination of 
multicore network processor hardware 
and Corero developed software, which is 
deployed on premises (at the customer 
location or a third party data centre) 
which inspects all IP network traffic in 
real time before it is allowed to pass into 
the customers’ IT environment to remove 
unwanted and malicious Internet traffic  
and ensure only good traffic enters.

Annual Report & Accounts for the year ending 31 December 2013

OVERVIEW

Chairman’s  
Statement

Initial SmartWall TDS 
discussions with 
potential customers 
have been 
encouraging and 
validate the view 
Corero has of the 
market opportunity

Corero’s 2014 launch 
of the SmartWall 
Threat Defence System 
was an important 
milestone achievement 
from a strategic plan 
established in 2012 to 
build a market leading 
network security 
business focused on 
delivering scalable 
network security 
protection to counter 
multiple forms of 
cyber threats such as 
DDoS attacks at any 
performance level

Jens Montanana 
Chairman

Overview 

Corero defines its go-to-market by 
positioning its products as a First Line of 
Defense solution to help organisations 
stop DDoS attacks and cyber threats. This 
has enabled Corero to target a fast 
expanding market which a leading analyst 
IDC has forecast will be one of the highest 
growth areas in the IT security market. 

During the last year, we made significant 
progress across many facets of the 
business including developing the  
sales organisation and advancing the 
development of our next generation 
product, SmartWall TDS. Revenues in  
2013 did not grow over the prior year as 
Corero transitioned its business entirely  
to its First Line of Defense solution. This 
repositioning encouragingly did deliver 
good growth in the second half of 2013 
as order intake rose 23% year over year.

The focus for 2014 is to continue building 
on this growth. Revenues from Corero’s 
existing First Line of Defense products 
targeting commercial and public sector 
organisations will be augmented by 
additional new revenue streams from 
SmartWall TDS sales targeted at securing 
Internet cloud environments for: Service 
Providers, Hosting Providers and 
Managed Security Service Providers.  
We expect to generate incremental 
revenues from sales to this new market 
opportunity for Corero in the second  
half of 2014. 

The SmartWall TDS product has been 
designed to be a highly scalable threat 
defence solution to enable Internet service 
and Cloud providers the ability to offer 
comprehensive DDoS and cyber attack 
protection to their customers at industry 
leading performance levels. Strong 
interest has been generated from a 
number of important customers. 

The sale of Corero Business Systems 
Limited (“CBS”) on 1 August 2013 enabled 
us to repay our outstanding debt early, 
strengthened the Group’s balance sheet, 
and provided the capital for funding the  
next generation SmartWall TDS product 
development and making the appropriate 
sales and marketing investments.

Strategic focus

The Company’s strategy is to remain 
focused on the network security market 
and to build a strong market position 
leveraging our advanced technology to 
create a sustainable business which offers 
strong growth prospects. The key strategic 
focus areas, main drivers for success and 
risks are summarised on page 15. 

Our 2014 plans are focused on the launch 
and customer deployment of the new 
SmartWall TDS product as well as 
broadening the customer base for our 
existing enterprise focused DDoS attack 
prevention solutions in order to drive 
revenue growth whilst continuing to invest  
in our engineering development. As with  
all new product introductions, successful 
commercialisation relies on sales, 
marketing and technical support being 
directed for maximum effect and achieving 
reference wins to establish repeatable 
revenue streams. A solid foundation has 
been created and we are receiving strong 
indications of user satisfaction to support 
our strategy. 

Market dynamics

The network security market continues to 
show strong growth fundamentals driven 
by the continued and in some cases 
exponential increase in cyber threats and 
the growing importance of the Internet for 
most commercial and public sector 
organisations.

IDC, one of the leading IT industry 
analysts, has forecast that the DDoS 
protection market will be one of the 
highest growth areas in the IT security 
market more than doubling in size in the 
period 2012 to 2017 (to reach $870 million 
in 2017). In addition, in light of the 
requirement to protect against the 
changing threat landscape, IDC has 
defined a new security segment, 
Specialized Threat Analysis and 
Protection, a market which Corero’s First 
Line of Defense solution addresses. This 
market is forecast to have a compound 
annual growth rate of over 40% from  
2012 to 2017 with revenues reaching  
$1.2 billion in 2017. 

Despite the increase in threats and the 
number of attacks, research from Corero 
reveals that many businesses are failing to 
take adequate measures to protect 
themselves against the threat of a DDoS 
attack. A survey of 100 companies 

revealed that despite media reports of the 
cost of downtime and the potential for 
DDoS attacks to mask greater threats, 
businesses are failing to put in place 
effective defences or plans to mitigate the 
impact of a DDoS attack. This is partly a 
result of a lack of understanding of the 
threats, and that traditional security 
solutions do not provide the required 
protection, and challenges in 
organisations’ prioritising IT security 
spend. There are efforts by governments 
and industry regulators in a number of 
geographies to increase this awareness.  
For example in the UK, the Department for 
Business, Innovation and Skills (BIS) wrote 
to the chairmen of the top 350 UK listed 
companies in the summer of 2013 to 
undertake a cyber health check survey.  
This type of awareness raising and 
increasing Corero brand awareness  
are having a positive impact on 
Corero’s success.

Our view is that it is critical for 
organisations to understand what cyber 
threats are traversing their network so they 
have visibility to their level of exposure and 
can take appropriate action to stop 
unwanted and malicious traffic including 
DDoS attacks. Corero’s First Line of 
Defense solution provides this visibility 
and allows organisations to proactively 
manage cyber threats. 

We believe that organisations need to 
transform their information security 
environment, to ensure they can get ahead 
of cyber threats or at least try and keep 
pace. Otherwise, the gap between an 
organisation's security posture and the 
cyber threats it faces will continue to  
grow potentially threatening the 
organisation’s survival. 

Shareholders

Corero’s shares are listed on AIM in  
London. The Company's largest external 
shareholders include Blackrock, Herald and 
Sabvest. I’d like to thank them and all our 
shareholders for their continuing support.

Outlook

The SmartWall Threat Defense System 
product, the first phase of which was 
launched to the market in February 2014, 
provides Corero with a strong growth 
opportunity, opening up additional 
markets through enabling Internet service 
and Cloud providers to protect their IT 
infrastructure and, importantly, providing 

them with a platform from which they 
can deliver security services to their 
customers to protect against DDoS 
attacks and cyber threats. 

The positive momentum in the second half 
of 2013, combined with the strong financial 
position and cash to execute Corero’s 
growth plans, gives us confidence that we 
will be able to successfully exploit the 
considerable opportunities available in this 
dynamic market.

Annual Report & Accounts for the year ending 31 December 2013

STRATEGIC REPORT

Our  
performance

Corero’s balance 
sheet has been 
strengthened 
by the sale of 
Corero Business 
Systems with net 
consideration of 
$16.5 million

In 2013 Corero had 
continued success 
in retaining and 
winning new 
customers

Financial performance

For the year ended 31 December 2013,  
the Group reported an EBITDA loss  
before depreciation, amortisation, 
financing and profit on sale of CBS of  
$4.5 million (2012: $3.1 million) including 
an EBITDA profit from discontinued 
operations of $1.7 million (2012: 
$2.7 million), comprising CBS which  
was disposed on 1 August 2013. 

The profit for the year after taxation 
amounted to $8.2 million (2012: loss  
$5.9 million) and comprised the following:
•
Loss for the year after taxation from
continuing operations of $8.5 million
(2012: loss $8.2 million);

• Profit after taxation from discontinued

operations of $1.4 million (2012:
$2.3 million); and

• Profit from the sale of discontinued

operations of $15.2 million.

The loss from continuing operations includes:

• Unrealised exchange loss of $0.2

million (2012: loss $0.3 million) arising
on an intercompany loan;

• Central costs of $1.1 million (2012:
$1.2 million) which relate to the
Company’s finance function as well
as the costs associated with the
Company’s listing on AIM; and

•

Finance costs of $0.4 million (2012:
$0.5 million) comprising interest
on the loan notes issued by Top
Layer Networks, Inc. (“Top Layer”
subsequently renamed Corero
Network Security, Inc.) as part of the
purchase consideration for Top Layer.

The sale of CBS provided an attractive 
opportunity to realise the Company’s 
investment in the business at a compelling 
cash valuation:

• A multiple in excess of 8.0 times the
CBS earnings before development
costs capitalised, depreciation,
amortisation and financing for the
year ended 31 December 2012; and

•

In excess of 2.2 times the CBS
revenues for the year ended 31
December 2012.

The earnings per share, including the profit 
from discontinued operations and profit on 
the sale of discontinued operations, was 
11.3 cents (2012: loss 9.7 cents). 

The Group’s net assets at 31 December 
2013 were $34.0 million (2012: $19.3 million).

Annual Report & Accounts for the year ending 31 December 2013  05

Review of performance and 
performance indicators

The Directors monitor a number of 
metrics, both financial and non-financial, 
on a monthly basis. The most important 
of these, for the continuing business,  
are as follows:

• Order intake: $9.2 million for the year
ended 31 December 2013 (2012:
$10.4 million);

• Gross margin: 65% for the year ended

31 December 2013 (2012: 70%);

• Operating expenses: $12.9 million

(2012: $13.7 million); and

• Net cash: $9.5 million at 31 December
2013 (2012: net debt $1.3 million).

Although order intake in 2013 did not grow 
over the prior year as Corero transitioned 
its business entirely to its First Line of 
Defense solutions, the 23% growth in 
order intake in second half of 2013 was 
encouraging. The lower order intake 
resulted in revenue in 2013 being below 
the prior year. The gross margins in 2013 
were impacted by the reduction in revenue 
given certain fixed costs associated with 
Corero support and production functions, 
and increased investment in the services 
and support delivery capabilities in 2013. 
The operating expenses, gross of research  
and development costs capitalised of 
$3.8 million (2012: $2.4 million), of 
$16.7 million were in line with the prior  
year (2012: $16.1 million) and reflect the 
investment in the Company's SmartWall 
TDS product.

The Group had a strong net cash  
position at 31 December 2013 which  
was positively impacted by the  
proceeds on the sale of CBS and  
the early repayment of the loan notes. 

Review of the Company’s business 

Highlights of 2013 include:

• Appointment of David Ahee, who has
extensive experience in establishing
enterprise and channel sales strategies
internationally, as Senior Vice
President Global Sales

• Progress in next generation

product development

• Launch of the SmartWall TDS
product in February 2014

• Developed a reporting platform

utilising operational intelligence tools
to enhance Corero’s SecureWatch
managed security services

• Awarded “Best IT Products & Services
for Finance, Banking & Insurance” by
Network Product’s Guide

• Order intake of $5.1 million in the six
months ended 31 December 2013
increased 23% over the comparative
period in 2012

• Significant customer wins:

• Second half 2013 order intake

included 15 customers with orders
exceeding $100,000 (compared to 7
in second half of 2012 and 9 in the
first half of 2013)

New customer wins included significant 
orders from a UK infrastructure provider, 
two US energy utilities, two South 
American service providers, two US 
regional banks, a French insurance group, 
an Asian provider of on-line games, a web 
hosting company, a provider of real estate 
and mortgage portfolio management 
information services, a large US city 
corporation, a Brazilian state ministerial 
department and a government public 
relations ministry.

Material orders (upgrades and support 
contract renewals) from existing 
customers included a leading industrial 
group, a leading price comparison web 
site, Camelot (the UK Lottery operator), 
two US university colleges, a Middle East 
investment services firm, a global 
electronics manufacturing services group, 
two multi-national banking groups, one of 
the leading on-line gaming companies, a 
leading medical equipment manufacturer, 
a leading international energy group, City 
Index, a European telecommunications 
service provider, a national air traffic 
control provider, and one of the largest 
newspaper publishers in the US. 

Cash and treasury 

The closing cash balance was $9.8 million 
(2012: $4.9 million). The Group had debt 
at 31 December 2013 of $0.3 million 
comprising the balance on a receivables-
backed working capital facility (2012:  
$6.2 million which comprised loan notes 
of $5.8 million and a term loan of 
$0.6 million which was repaid in 2013). In 
October 2013, Corero elected to repay its 
existing loan notes with a face value of 
$5.0 million in full, together with accrued 
interest of approximately $1.2 million, and 
in advance of their maturity date in March 
2014. The loan notes were issued in 
March 2011 as part of the consideration 
paid for the acquisition of Top Layer. The 
loan notes accrued interest at a rate of 
8% per annum and were secured on the 
assets of Top Layer.

The net reduction in cash from operating 
activities in the year ended 31 December 
2013 was $7.5 million (2012: $5.1 million).
In 2013, the Company raised $6.2 million 
(before expenses) of which the directors 
contributed $4.2 million.

At the end of the year, the Group had a 
receivables backed financing facility of 
$2.0 million which is committed for a 
period of one year and is repayable on 
demand. The Group company has 
complied with the financial covenants 
relating to this facility.

What  
we do

The Corero First Line of Defense 
products and services stop DDoS 
attacks and cyber threats

OUR TECHNOLOGY

A high performance network appliance which is deployed on premises (at the customer or managed location) or in service provider 
networks. The appliance inspects Internet traffic in real time before it is allowed to pass into the customers protected IT environment  
to ensure unwanted and malicious Internet traffic is removed.

•

The Corero Patented
Dynamic Threat
Assessment technology
uses several algorithms
including advanced
challenge-response
techniques to categorise
all sources as unknown,
trusted, suspicious or
malicious based upon
their real-time behaviours.

•

The Corero Request/
Response Behaviour
Analysis controls access
to downstream devices
based upon a source’s
“behaviours” which
enables enforcement of
usage standards on every
source IP address which
provides detection of
application-layer denial
of service attacks, as
well as other unwanted
behaviours and blocks
them before they reach
the victim devices.

•

The Corero Protocol
Validation Engines inspects
all packets of a network
and/or application
transaction and compares
the observed content and
characteristics to what is
allowed, expected, or
required, based upon the
protocol specifications and
known implementations,
and takes the appropriate
real time actions (e.g.
detection/blocking) of
the violations.

• Corero has a real-time
reputation engine,
ReputationWatch, that
provides automated
real-time defence against
previously identified DDoS
attack sources. In addition,
IP address geolocation
technology enables
enforcement of security
policies based on national
origin of IP addresses.

OUR SERVICES

Threat 
Update

Reputation 
Watch

An automated protection update service that provides Corero customers with timely, 
proactive protection from the latest security threats. The subscription service delivers 
frequent protection updates and security advisories. These updates include updated 
vulnerability and attack signatures to provide the most current, effective network threat 
monitoring. Security advisories, an important aspect of the Threat Update Service, 
inform customers of newly discovered threats, and recommend any actions that might  
be necessary to obtain protection against the threat.

Enables customers to automatically block malicious IP addresses. Corero continuously 
receives data feeds from global intelligence across the Internet to determine the current 
threat status of malicious or suspicious IP addresses. Using IP reputation-based 
information, ReputationWatch automatically identifies and blocks access from suspicious 
sites including sources that have participated in DDoS attacks, systems delivering 
specially crafted denial-of-service exploits, anonymised IP addresses behind proxies, 
phishing sites, and spam sources. ReputationWatch also allows customers to block or 
alert on access from countries with which they do not transact business for example by 
choosing to block or set rate limits on all traffic from a nation or geography. 

SecureWatch

A service which ensures that customers’ First Line of Defense solutions are always  
up to date, running at optimum performance, and continuously protecting customers’  
IT infrastructure against the latest threats.

SecureWatch 
Plus

A comprehensive suite of DDoS defence configuration, optimization, 24x7 monitoring  
and attack mitigation services. These services are customised to meet the security 
requirements and business goals of each customer. SecureWatch PLUS includes access 
to experts to assist in the realisation of the desired DDoS defence solution starting with 
the organisation-specific implementation, commissioning and testing, continuing with 
round-the-clock monitoring, and immediate response in the event of a DDoS attack.

2013 worldwide IT security 
spending will be $17.9 billion 

Source: IDC

Number of companies 
suffering cyber attacks to 
steal commercial secrets 
doubled in 2012-13 

The Internet has transformed the way commercial and public sector 
organisations do business
Organisations today are embracing technology to enhance the productivity of their 
employees, generate new revenue sources and improve their operating efficiency.  
These technologies include cloud services, mobile computing, online services and  
social networking. This greater reliance on information technology has significantly 
increased the attack surface within organisations that is vulnerable to potential security 
attacks. As a result organisations are having to make significant investments in IT 
security to help protect against a myriad of potential threats. 

The threat landscape has evolved

“Cyber attacks are one of the top four threats to our national security and cyber-crime  
is costing our economy billions of pounds a year. And as businesses and government 
move more of their operations online, the scope of potential targets will continue to  
grow. It’s a race: to build sufficient cyber defences to match the growing volume and 
dependence of our online economic, security and social interests.”

(approaching $1 billion)

Source: IDC

Existing security solutions do not protect against next-generation threats
Though firewalls are still a critical and necessary component of any IT network, they  
are no longer the best type of device to deploy as the network’s first line of defence. 
Whilst firewalls serve many purposes, they do not have complete Layer 3–7 protection. 
Attackers know these limitations and have devised attacks that can evade or overwhelm 
a firewall, as well as the secondary security devices behind the firewall, such as intrusion 
prevention systems. 

The opportunity for Corero
Organisations need to respond to the increased risk presented by the growing number 
of DDoS attacks and cyber threats – a security device specifically designed to detect  
and stop unwanted traffic before it can overrun the IT infrastructure causing performance 
issues, security exposures and even catastrophic outages.

This new first line of defence must be able to identify malicious attack traffic even if it 
mimics legitimate traffic and the true customer communications that businesses want 
and welcome.

The Corero First Line of Defense solution applies industry best practices as well as 
sophisticated analysis techniques to thoroughly inspect traffic in order to stop DDoS 
attacks and cyber threats. The Corero solution stops unwanted traffic that slows the 
infrastructure and frustrates users, and in the process protects the existing infrastructure 
and enables maximum uptime of business applications.

THE COMPETITIVE ENVIRONMENT

Corero is a leader in protecting enterprises and public sector 
organisations against DDoS attacks and cyber threats. We have 
defined the market for on premises First Line of Defense and  
have developed the following key competitive advantages that  
we believe will allow us to extend our leadership position:
• Always-on protection that blocks both network-layer flooding
attacks, as well as the more difficult to detect, low and slow
application-layer attacks.

• Granular configuration of security policies in order to allow
legitimate traffic to pass while blocking unwanted traffic.

• Broad security coverage – Inspection of every packet and
every flow (using Deep Packet Inspection) rather that a
sample-based approach used by most competitors.

• Purpose-built security appliance for high speed traffic
inspection using a multi-core processor architecture.

• Competitive price-performance resulting in the lowest

total cost of ownership for the end user.

• Expert security knowledge and technical support provided

by Corero’s 24x7 Security Operations Centre.

Our next generation product, SmartWall TDS, was launched  
on 3 February 2014 to address the Internet service provider and 
hosting provider markets. It adds key features like asymmetric 
inspection, and multi-tenancy to allow our First Line of Defense 
solutions to be deployed in service provider networks and hosting 
data centres as a services-oriented platform. Service providers 
and hosting providers can now deploy this platform in a modular 
and scalable fashion to not only protect their own infrastructure  
but more importantly to roll out revenue generating DDoS 
protection services to multiple customers. SmartWall TDS extends 
our current competitive advantages with the following key features:

OPPORTUNITIES

The awareness of cyber-crime and the impact on businesses 
(small and large) is increasing with Board room accountability and 
regulatory focus in certain industries, such as financial services. 
We expect this trend to have a positive impact on our market.
Ernst & Young’s Global information Security Survey 2013 reported  
that 50% of respondents indicate that their budgets will increase 
anywhere from 5% to 25% or more in the next 12 months, and  
14% of spend in the coming 12 months will be on security 
innovation (emerging technology).

KEY MARKET CHALLENGES

• Robust security coverage – comprehensive network

security protection against layer 3 and layer 4 for both
IPv4 and IPv6 traffic.

•

Industry-leading density, scalability and performance
– protection is provided through configurable access policies
with scalability from 10Gbps to 1Tbps in a single rack.

• Green, energy-efficient platform – energy-efficient design
with front-to-back cooling which fully supports economic
and environmental initiatives.

• Powerful centralised management for configuring,

controlling, and monitoring all SmartWall TDS appliances
from a central location.

•

Flexible deployment configurations – multiple appliances
can be distributed to key control points in the provider
network or centrally combined in 1 Rack Unit shelves in
various configurations.

• Single solution to deliver comprehensive threat protection,
always-on connectivity, and complete visibility with the
family of SmartWall appliances.

The Corero principal competitors are other DDoS defence 
equipment manufacturers such as Arbor Networks, Inc.  
and Radware Limited.

Corero is targeting a high growth security market; the DDoS 
market is forecast to double in the period 2012 to 2017 (Source: 
IDC) to $870 million. The existing Corero DDS product is targeted 
at the enterprise on premises DDoS protection market. The new 
SmartWall TDS product is targeted at the service provider and 
hosting provider market.

The market for security products and services is competitive and 
characterised by rapid changes in technology, the evolving cyber 
threat landscape, customer requirements, and industry standards 
and frequent new product introductions and improvements. We 
need to be focused on our chosen market and deliver continuous 

innovation to stay ahead of our competition. Corero will  
address this challenge by working closely with our customers  
and prospects, to leverage the flexibility of our platform 
technology to deliver continuously evolving leadership  
protection against the latest DDoS attacks and cyber threats.

STRATEGIC REPORT

Our strategy 
for sustainable 
growth

The Corero strategy is to protect against a 
continuously evolving spectrum of DDoS attacks 
and cyber threats that have the potential to 
impact any Internet connected business

The Company is dedicated to improving the security of the Internet through the 
deployment of its innovative First Line of Defense solutions. Corero products and 
services provide our customers with protection against a continuously evolving  
spectrum of DDoS attacks and cyber threats that have the potential to impact any 
Internet connected business. 

Corero provides the opportunity to enhance defence-in-depth security architectures  
with an important additional layer of security capable of inspecting traffic arriving from 
the Internet in real time and applying access policies designed to match the needs of  
the business. The goal of the Corero First Line of Defense security layer is to protect  
the customer’s network infrastructure, online services and confidential data from 
suspicious or malicious Internet traffic.

The Company’s strategic objectives and plans are summarised below:

MARKET

To gain market endorsement of the value proposition of a new layer of cyber security 
protection – First Line of Defense – which is designed to be deployed in front of  
Firewalls, Intrusion Prevention Systems and other IT security infrastructure devices,  
and to establish Corero as a market leading solution for protection against DDoS and 
other cyber threats. The Company is planning to raise its profile through a progression  
of referenceable customer deployments and playing an active role as a thought leader  
in cyber security protection. 

Service providers and their customers are both impacted by the challenges of  
DDoS attacks and cyber threats. These attacks have grown in size, frequency and 
sophistication in recent years. Enterprises are increasingly calling on their service 
providers to assist them in the detection, analysis and mitigation of such attacks  
before they have an impact on their operations, and ultimately their business. The  
Corero SmartWall TDS, launched on 3 February 2014, has been developed for the 
service provider market and gives service providers the opportunity to deliver First 
Line of Defense, always on, threat protection and visibility to their customers as a  
value added security service. SmartWall TDS provides access to a new market for 
Corero to complement its current enterprise focused product offering.

The SmartWall 
TDS opportunity: 
Enterprises are 
increasingly calling 
on their service 
providers to 
assist them in the 
detection, analysis 
and mitigation of 
DDoS attacks and 
cyber threats before 
they have an impact 
on their operations,  
and ultimately  
their business

TECHNOLOGY

To develop a software-based technology platform leveraging high performance  
multicore processor hardware as well as virtual machine based software deployments 
to deliver the Corero industry leading First Line of Defense solutions in a scalable,  
high performance and “open” manner capable of interfacing with other security  
hardware and software solutions. 

SALES

To enhance the Corero sales and business development capability to drive organic 
revenue growth and expand our geographical sales organisation to access new 
customers in new markets. Corero is committed to a channel sales strategy, focused  
on selling through partners, both distributors and resellers. The sales objectives will  
be achieved through a combination of strong sales leadership, sales tools and programs  
to drive sales growth. The sales effort will continue to be underpinned by strong post 
sales customer support. 

MANAGEMENT AND EMPLOYEES

To have a management team with the experience and skills to manage new technology 
investment and product innovation which connects with the market opportunity to deliver 
strong revenue growth. The Group will align additional investment in headcount with 
revenue goal achievement. 

PRINCIPAL RISKS AND UNCERTAINTIES

The principal risks and uncertainties for Corero are:

•

•

•

•

•

 Market awareness: We need to invest in targeted public relations and marketing
to raise market awareness of Corero and our solutions. If we are not successful in
connecting with the market it will compromise our growth plans.

 Technology change and innovation: Our market is competitive and characterised
by rapid changes in technology, customer requirements and frequent new product
introductions and improvements. To grow, we need to be focused on our chosen
market and deliver continuous innovation to stay ahead of our competition.

 People: Retaining and recruiting people with the necessary skills and
characteristics. Revenue growth requires a strong sales and business development
capability. We operate in a high growth market with new players emerging. If we are
unable to recruit and retain the right skills this will compromise our growth plans.

 Partner engagement and development: Our partner focused sales model requires
us to have strong partner relationships to ensure our mutual business interests are
maximised. Failure to successfully execute our channel strategy will compromise our
growth plans.

 Geographic distribution: Finding the right balance for geographic growth to avoid
overextending our resources by expanding too fast or spreading ourselves too thin.

Directors’ Report

for the year ended 31 December 2013

Group results

The Group’s Statement of Comprehensive Income on page 27 shows a profit for the year of $8.2 million (2012: loss $5.9 million).

Going concern

The financial position, cash flows and borrowing facilities are described in the Strategic Review on pages 4 to 5. 

Forecasts and projections, taking into account reasonably possible changes in trading performance, show that the Company  
and Group will be able to operate within the level of current cash balances and facilities.

The Directors are satisfied, in view of the cash reserves of $9.8 million (2012: $4.9 million) held on the balance sheet at 31 December 2013 
and receivables-backed financing facility of $2.0 million, that the Company and the Group have adequate resources to continue operating 
for the foreseeable future. For this reason the going concern basis has been adopted in preparing the accounts.

Dividends

The Directors have not recommended a dividend (2012: $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 25 to the financial statements. As at the date of this report, 85,637,416 ordinary shares of 1p each (‘ordinary 
shares’) were in issue and fully paid with an aggregate nominal value of $1.3 million.

The market price of the ordinary shares at 31 December 2013 was 17.8p and the shares traded in the range 12.8p to 31.0p during the year.

Issue of shares

At the AGM held on 13 June 2013 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 £285,458. It is 
proposed at the forthcoming AGM to renew the authority to allot relevant securities up to an aggregate nominal amount of £285,458, 
being one-third of the nominal value of the current issued share capital.

Also at the AGM held on 13 June 2013, 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 £85,637 without 
application of the statutory pre-emption rights contained in section 561 (1) of the Act. It is proposed at the forthcoming AGM to renew 
the authority to allot relevant securities wholly for cash up to an aggregate nominal amount of £85,637 being 10% of the current nominal 
value of the issued share capital, without application of the statutory pre-emption rights.

Financial risk management objectives and policies

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 to reduce debt. 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 are 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 finance function under the direction of the Group Financial Controller.  
The Group Financial Controller reports to the Board on the implementation of Group treasury policy.

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 the risk that the Group will 

encounter difficulty in meetings its financial obligations as they fall due. Liquidity risk is managed centrally by the finance function. 
Budgets are agreed by the Board annually in advance 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 will seek 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.

Annual Report & Accounts for the year ending 31 December 2013

Directors’ Report continued

for the year ended 31 December 2013

Financial risk management objectives and policies continued

Treasury management continued

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 18).

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.

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

• Cash flow interest rate risk – the Group’s policy is to minimise interest rate cash flow risk exposure on its financing. 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 is no material impact on the Group’s Statement of Comprehensive Income 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.

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 core software 
in response to user demand, and particularly the changing IT security threat landscape, and changes in software technology. During  
the year the Group enhanced its existing products and developed new products. A capital investment for continuing operations of 
$3.8 million (2012: $2.4 million) was made during the year. Amortisation of $0.3 million (2012: $0.7 million) was charged to the Statement 
of Comprehensive Income during the year. 

Employees

The quality and commitment of the Group’s employees has played a major role in the Group’s business success. 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

The AGM will be held at the offices of FinnCap Ltd, 60 New Broad Street, London, EC2M 1JJ, on 18 June 2014 at 9.30 a.m. The notice 
convening the meeting is on page 62 together with details of the business to be considered. 

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.

A resolution to re-appoint BDO LLP for the ensuing year will be proposed at the AGM.

All directors have access to the advice and services of the Company Secretary. There is also a procedure in place for any director to 
take independent professional advice if necessary, at the Company’s expense.

The Board also ensures that the principal goal of the Company is to create shareholder value, while having regard to other stakeholder 
interests and takes responsibility for setting the Company’s values and standards.

It meets at least twice a year and reviews and advises upon the remuneration and benefits packages of the executive directors. 
The remuneration of the chairman and non-executive directors is decided upon by the Board of Directors. 

The Remuneration Committee met twice in the year ended 31 December 2013. The attendance of individual Committee members

Due to the size of the Board of Directors, the directors do not consider there to be any need for a nominations committee. Issues that 
would normally be dealt with by a nominations committee are handled by the Board of Directors. The Board of Directors will review the 
need for a nominations committee on a regular basis.

Internal controls

The directors are responsible for the Group’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 Group’s system of internal control is designed to manage, 
rather than eliminate, the risk of failure to achieve the Group’s business objectives and can only provide reasonable, and not absolute, 
assurance against material misstatement or loss.

The Board continually reviews the effectiveness of other internal controls, including financial, operational, compliance controls and risk 
management. There were no specific reports tabled during the year ended 31 December 2013. 

The Group operates a risk management process, which is embedded in normal management and governance processes. As part of the 
annual strategic planning and budgeting process, the Group documents 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 Group 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, monthly treasury and cash flow reports and forecasts to the Board. 

The Audit Committee 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 of Directors for consideration.

The Board of Directors makes an annual assessment of the effectiveness of the Group’s internal control system, including financial, 
operational and compliance controls, before making this statement. The Board of Directors also considers issues included in reports 
received during the year, how the risks have changed during the year and reviews any reports prepared on internal controls by 
management and any issues identified by external auditors. 

The Board of Directors does not believe it is currently appropriate to establish a separate, independent internal audit function given the 
size of the Group.

Remuneration report

The Remuneration Committee’s principal function is to set remuneration of the Group’s executive directors and management to ensure 
they are fairly compensated. 

Basic salaries are set to ensure high quality executive directors and management are attracted and retained by the Group. They reflect 
the knowledge, skill and experience of each individual director. Bonuses are non-pensionable and only payable if the Remuneration 
Committee assesses the director’s achievements as worthy of the award.

The Remuneration Committee is also responsible for ensuring the Group’s share option schemes are operated properly. Details of 
directors’ share options at 31 December 2013 are disclosed in note 30 of the Financial Statements.

Details of directors’ remuneration for the year ended 31 December 2013 is set out in note 27 of the Financial Statements. Jens 
Montanana has elected to waive the fees payable to him for the financial year ended 31 December 2013.

Ashley Stephenson, executive director, has a service agreement which provides for the payment of six months’ base salary if the 
agreement is terminated by the Company without cause. 

Andrew Miller, executive director, has an employment agreement which is terminable by either party on not less than three months’ 
written notice increasing by one month at the end of each complete 12 month period of continuous employment provided that the 
notice period shall not exceed six months in total. The agreement contains provisions for early termination in certain circumstances.

None of the Non-executive Directors has a service agreement. Letters of appointment for Jens Montanana, Richard Last and Andrew 
Lloyd are for 12 month terms and provide that the appointment may be terminated by either party giving to the other not less than three 
months’ notice.

Statement of Directors' Responsibilities 

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 and Company financial statements in accordance with International Financial Reporting Standards as adopted by 
the European Union (IFRSs). 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 applicable IFRSs have been followed, 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.

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 ongoing integrity of the 
financial statements contained therein.

other than the Company and the Company’s members as a body, for our audit work, for this report, or for the opinions we have formed.

Respective responsibilities of directors and auditors

from branches not visited by us; or

Notes to the Financial Statements

1. General information

Presentation currency

These consolidated financial statements 
are presented in US Dollars (“$”) which 
represents the presentation currency of  
the Group. The average $-GBP sterling 
(“GBP”) exchange rate, used for the 
conversion of the statement of 
comprehensive income, for the 12 months 
ended 31 December 2013 was 1.57 (2012: 
1.59). The closing $-GBP exchange rate, 
used for the conversion of the Group’s 
assets and liabilities, at 31 December 2013 
was 1.66 (2012: 1.63). 

Corero Network Security plc is a public 
limited company incorporated in the 
United Kingdom under the Companies  
Act 2006.

2. Significant accounting policies

2.1 Basis of preparation

The Group and parent Company financial 
statements have been prepared in 
accordance with EU endorsed 
International Financial Reporting 
Standards (IFRS), International Financial 
Reporting Interpretations Committee 
(IFRIC) interpretations and those parts  
of the Companies Act 2006 applicable  
to companies reporting under IFRS. 

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  
31 December 2015. The cash flow 
projections have been subjected to 
sensitivity analysis at the revenue, cost 
and combined revenue and cost levels. 
The cash flow projections show that the 
Group will maintain a positive cash 
balance until at least 31 December 2015.

As a result, the directors are of the opinion 
that the Group has adequate working 
capital to continue as a going concern for 
the foreseeable future and, in particular, for 
a period of at least 12 months from the date 
of approval of these financial statements. 

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 2013. 

Subsidiaries are entities controlled by 
the Group. Control is deemed to exist 
when the Group has the power, directly  
or indirectly, to govern the financial and 
operating policies of an entity so as to 
obtain benefits from its activities. 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.

The results of operations disposed during 
the year are included in the consolidated 
statement of comprehensive income up 
to the date of disposal. A discontinued 
operation is a component of the Group’s 
business that represents a separate 
major line of business that has been 
disposed of. Discontinued operations are 
presented in the consolidated statement 
of comprehensive income as single lines 
which comprise the post-tax profit or loss 
of the discontinued operation up to the 
date of sale along with the post-tax gain 
or loss on the disposal of the assets less 
costs to sell of discontinued operations. 

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.

2.4 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 exchange, 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.

Non-controlling interests are initially 
recognized at their fair value. The total 
comprehensive income of non-wholly 
owned subsidiaries is attributed to owners 
of the parent and to the non-controlling 
interests in proportion to their relative 
ownership interests.

2.5 Revenue

Revenue is measured at the fair value of 
the consideration received or receivable 
and represents the amounts receivable for 
services provided in the normal course of 
business, net of all related discounts and 
sales tax.

The Group has adopted the following 
policy in respect of revenue recognition:

1. Hardware and Software Products
When a sales arrangement contains 
multiple elements, such as hardware and 
software products, licenses and/or 
services, the Group allocates revenue to 
each element based on a selling price 
hierarchy, having evaluated each 
deliverable in an arrangement to 
determine whether they represent 
separate units of accounting. A deliverable 
constitutes a separate unit of accounting 
when it has standalone value.

34  Corero Network Security plc

Annual Report & Accounts for the year ending 31 December 2013

Notes to the Financial Statements continued

The selling price for a deliverable is based 
on its vendor specific objective evidence 
(“VSOE”) if available, third party evidence 
(“TPE”) if VSOE is not available, or best 
estimated selling price (“BESP”) if neither 
VSOE nor TPE is available. In multiple 
element arrangements where more-than-
incidental software deliverables are 
included, revenue is allocated to each 
separate unit, accounting for each of the 
non-software deliverables and to the 
software deliverables as a group using the 
relative selling prices of each of the 
deliverables in the arrangement based on 
the aforementioned selling price hierarchy.

The Group establishes the VSOE of selling 
price using the price charged for a 
deliverable when sold separately. The TPE 
of selling price is established by evaluating 
similar and interchangeable competitor 
products or services in standalone sales 
to similarly situated customers. The best 
estimate of selling price is established 
considering both internal and external 
factors such as pricing practices, 
customer pricing strategies, margin 
objectives, market conditions, competitor 
pricing strategies, and industry  
technology lifecycles.

2. Consulting and Professional Services
Revenue from the provision of consultancy 
and professional services is recognised as 
the work is performed.

3. Maintenance and Support Services
Revenue is recognised on a straight line 
basis over the life of the agreement.

2.6 Cost of sales

Cost of sales includes all direct costs 
associated with revenue generation, 
including services delivery, support costs 
and amounts charged by external third 
parties for services and goods directly 
related to revenue. Examples of such 
costs would include, but not be limited to, 
external consultants and third party 
hardware and software costs. 

2.7 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 
Statement of Comprehensive Income. 

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 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 translation reserve. Such translation 
differences are recognised in profit or  
loss on the disposal of the UK operation.

2.8 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 Statement of 
Comprehensive Income.

After initial recognition, internally 
generated intangible assets are carried at 
cost less accumulated amortisation and 
any impairment losses.

Acquired intangible assets
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.

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, 
customer contracts and the related 
customer relationships.

After initial recognition, assets acquired as 
part of a business combination are carried 
at cost less accumulated amortisation and 
any impairment losses.

Corero Network Security plc

Annual Report & Accounts for the year ending 31 December 2013  35

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 –

3 or 5 years straight line

• Customer contracts and the related

customer relationships –
7 years straight line

• Capitalised development expenditure –

5 years straight line

Amortisation costs are included within 
operating expenses in the Statement  
of Comprehensive Income.

Methods of amortisation and useful lives 
are reviewed, and if necessary adjusted,  
at each reporting date.

2.9 Property, plant and equipment

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.

Subsequent costs are included in an 
asset’s 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 Statement of 
Comprehensive Income as incurred.

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

• Computer equipment –
2 to 4 years straight line

•

Fixtures and fittings –
2 to 5 years straight line

• Office equipment –

3 to 5 years straight line

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 is included in the Statement 
of Comprehensive Income.

2.10 Inventory

Inventory is stated at the lower of cost  
or net realisable value. Cost is computed 
using standard cost, which approximates 
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. 

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

2.11 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 to which the  
asset belongs is determined.

The recoverable amount of an asset or a 
cash-generating unit is the higher of its fair 
value less costs to sell and its value in use. 
The value in use is the present value of the 
future cash flows expected to be derived 
from an asset or cash-generating unit. This 
present value is discounted using a pre-tax 
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 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 Statement of 
Comprehensive Income.

Goodwill acquired in a business 
combination is, from the acquisition date, 
allocated to each of the cash-generating 
units or groups of cash-generating units 
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 
cash-generating units if the recoverable 
amount of the unit is less than the carrying 
amount of the unit. The impairment loss is 
allocated to reduce the carrying amount of 
the assets of the unit by first reducing the 
carrying amount of any goodwill allocated 
to the cash-generating unit, and then 
reducing the carrying amounts of the other 
assets of the unit pro rata.

If an impairment loss subsequently 
reverses, the carrying amount of the asset 
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 
Statement of Comprehensive Income. 
Impairment losses on goodwill are not 
subsequently reversed.

Notes to the Financial Statements continued

2.12 Leases

Where substantially all of the risks and 
rewards incidental to ownership of a 
leased asset are transferred to the 
Company (a “finance lease”), the asset is 
treated as if it had been purchased 
outright. The amount initially recognised 
as an asset is the lower of the fair value of 
the leased property and the present value 
of the minimum lease payments payable 
over the term of the lease. The 
corresponding lease commitment is 
shown as a liability. Lease payments are 
analysed between capital and interest. 
The interest element is charged to the 
Statement of Comprehensive Income over 
the period of the lease and is calculated 
so that it represents a constant proportion 
of the lease liability. The capital element 
reduces the balance owed to the lessor.

Where substantially all of the risks and 
rewards incidental to ownership are not 
transferred to the Company (an “operating 
lease”), the total rentals payable under the 
lease are charged to the Statement of 
Comprehensive Income on a straight-line 
basis over the lease term. The aggregate 
benefit of lease incentives is recognised 
as a reduction of the rental expense over 
the lease term on a straight-line basis.

2.13 Investments in subsidiaries

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

2.14 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, or because they 
are never taxable or deductible.

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.

2.15 Provisions

A provision is recognised when, as a 
result of a past event, the Group has a 
legal or constructive obligation, it is 
probable that an outflow of resources 
embodying economic benefits will be 
required to settle the obligation and a 
reliable estimate of the amount of such 
an obligation can be made.

Provisions are measured at the best 
estimate of the expenditure required to 
settle the obligation at the reporting date. 
When the effect is material, the expected 
future cash flows required to settle the 
obligation are discounted at the pre-tax 
rate that reflects the current market 
assessments of the time value of money 
and the risks specific to the obligation.

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 
Statement of Comprehensive Income 
when incurred. 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 
according to the original terms of these 
receivables. The amount of the provision  
is the difference between the carrying 
value and the present value of estimated 
future cash flows, discounted at the 
original effective interest rate. 

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

Corero Network Security plc

Annual Report & Accounts for the year ending 31 December 2013  37

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.

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.

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 Receivables-backed working 
capital facility

The Group makes use of a receivables-
backed working capital facility. Trade 
receivables are recognised as the Group 
retains the significant risks and benefits. 
The related funding is shown as a financial 
liability and accounted for on an amortised 
cost basis.

2.21 Standards and Interpretations not 
yet effective

There are no standards and interpretations 
that are issued but not yet effective at the 
date of authorisation of these financial 
statements that the Group reasonably 
expects will have an impact on disclosures, 
financial position or performance when 
applied at a future date. 

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, 
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.

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. Value in use 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 cash generating 
unit is set out in note 12.

Impairment of investments and 
intercompany balances (applies to the 
Company Financial Statements only)
The directors have reviewed the carrying 
value of the intercompany balances and 
cost of investments in subsidiaries of the 
Company with reference to current and 
future trading conditions. The investment 
and intercompany balances between the 
Company and Corero Network Security, 
Inc. and Corero Network Security (UK) 
Limited have been reviewed with 
reference to a valuation based on a 
discounted free cash flow which the 
directors consider to be an appropriate 
valuation methodology, in conjunction 
with the goodwill impairment review. 

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 
and uncertainties contained in the 
projections are detailed in the note 2.2. 

4. Segment reporting

Business segments

Subsequent to the sale of the Corero 
Business Systems division the Group is 
managed according to one business unit; 
Corero Network Security which makes up 
the Group’s reportable operating segment. 
This business unit forms the basis on 
which the Group reports its primary 
segment information to the Board, which 
management consider to be the Chief 
Operating Decision maker for the 
purposes of IFRS 8 Operating Segments. 

The loss before taxation for the year was 
$8.9 million (2012: $8.6 million). Included  
in the loss were the central costs of  
$1.1 million (2012: $1.2 million) which 
comprise mainly central and parent 
Company overheads relating to the  
Group management, the finance  
function and regulatory requirements.

8. Tax on loss on ordinary activities

Deferred tax credit for the year

The tax assessed on the loss on ordinary activities for the year differs from the weighted average  
UK corporate rate of tax of 23.25% (2012: 24.5%). The differences are reconciled below:

Total tax reconciliation 

Profit/(loss) before taxation

Theoretical tax charge/(credit) at UK Corporation tax rate 23.25% (2012: 24.5%)

Effect of:

– expenditure that is not tax deductible

– R&D tax credits

– accelerated capital allowances

– other timing differences

– relief for losses brought forward

As at 31 December 2013, the Group’s cumulative fixed asset timing differences were $17,000 (2012: $24,000) and no deferred tax asset 
has been recognised in respect of these items.

In addition, the tax losses at that date amounted to $41.8 million (2012: $37.7 million). This comprised UK tax losses of $6.8 million and 
US tax losses of $35.0 million. $2.1 million of the tax losses relates to US capitalised R&D deductions which will be available at an 
accelerated level for 3 years. $9.0 million of the tax losses relate to pre-acquisition US tax losses which can be offset against taxable 
profits over 18 years (there is a limit on the utilisation of pre-acquisition tax losses of $0.7 million per annum and any unused loss may 
be carried forward to subsequent periods). All other US tax losses will expire in 20 years from the end of the accounting period in which 
the loss arose.

The deferred tax asset of $1.4 million (2012: $1.9 million) at a rate 20% relating to the UK tax losses (after offsetting the deferred  
tax liability of $nil (2012: $0.4 million) relating to capitalised research and development expenditure) and the deferred tax asset of  
$12.3 million (2012: $9.7 million) at a rate of 35% relating to the US tax losses have not been recognised due to uncertainties as to the 
extent and timing of their future recovery.

10. Profit of the parent Company for the financial year

The Company has taken advantage of section 408 of the Companies Act 2006 and has not included an income statement in these 
financial statements. The parent Company’s profit for the year was $10,448,000 (2012: $430,000).

11. Earnings per share

Earnings/(loss) 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.

At the reporting dates there were no potentially dilutive ordinary shares. Therefore the diluted earnings/(loss) per share is equal to the 
earnings/(loss) per share.

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

Goodwill is allocated to the Group’s cash-generating unit (CGU) which at 31 December 2013 comprised Corero Network Security (“CNS”).

As at 31 December the carrying amount of goodwill allocated to this CGU is:

The recoverable amount for the CNS CGU was determined based on a discounted cash flow calculation using cash flow projections 
over a 10 year period (2012: 10 year period). 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: 

Forecast cash flow period

Extrapolated cash flow period

Cumulative annual growth rate (CAGR) for revenue used for the forecast/extrapolated period 

Revenue growth rates used beyond the extrapolated period

Discount rate

Discount rate required for recoverable amount to equal carrying amount

Percentage reduction in forecast revenue for recoverable amount to equal carrying amount

* the 2012 valuation model has been refined to be on a consistent basis with the 2013 model. The changes to the 2012 model reflect the assumption that cash flows 
occur on average halfway through each year and discounting after tax cash flows (at the point tax losses are fully utilised) with an after tax weighted average cost 
of capital (“WACC”) assuming a blended tax rate of 30.6% for the forecast and extrapolated period cash flows.

The pre-tax cash flows for the forecast period are derived from the most recent financial budget for the year ending 31 December
2014 and the plan for the year ending 31 December 2015 approved by the Board. The extrapolation for the period 2016 to 2023 is
based on management estimates (with the key assumptions set out below).

The future pre-tax cash flows are discounted by a weighted average cost of capital (“WACC”) of 15.5%.

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 2014 to 2018 (ii) and the discount rate.

i.

 The cash flow forecasts assume a CAGR revenue growth of 28.2% in the period 2014 to 2018 (63.8% for the period 2014 to
2015) and 3.7% for the period 2019 to 2023 (a CAGR of 14.1% for 10 year forecast period). The management of the Group
believe these growth rates are appropriate for the forecasts given the expected impact from the new product, SmartWall TDS,
which was launched in February 2014 and which is expected to start generating revenue from new customer sales targeted at
the service provider and cloud computing markets in 2014 and deliver a step change in revenue in the forecast period.

These growth rates are supported by the fact that the IT security market is forecast to grow strongly for the foreseeable future. 
Gartner for instance forecast that the IT security market will grow by a CAGR of 8.5% in the period 2012 to 2017 and IDC 
forecast that the DDoS protection market will grow from $270 million in 2012 to $870 million in 2017 (CAGR 18.2%). 

 The above market growth rates used in the future cash flow assumptions reflect that CNS is in the early stages of the 
commercial exploitation of its intellectual property. In addition, the business’ strategy is to continue to develop its product and 
solution offerings to remain a market leader in its chosen market 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 1.5% is considered reasonable as historically 
IT spend has exceeded GDP growth.

ii.

 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 3.75% (based on 30 year US government bonds), comparable company betas, an equity risk premium
of 5.5%, and small company risk premium of 4.5%. The WACC has been assessed based on that fact that the Company had no
gearing at 31 December 2013. 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 recoverable amount of the CNS CGU is highly sensitive to small changes in cash flow 
forecasts and discount rate assumptions, and there is no guarantee that the expected growth will be achieved. If the expected growth is 
not achieved, this could result in a requirement to impair the goodwill associated with the CNS CGU in the future. If the revenue growth 
in 2014 and 2015 is reduced by 20% (which in the assessment of management is reasonably possible), and a 10% reduction is made to 
overheads, this would result in an impairment of goodwill of $3.7 million. If the discount rate is increased by 20% (which in the 
assessment of management is reasonably possible), this would reduce the amount by which the CGU’s recoverable amount exceeds its 
carrying amount to $2.3 million.

Apart from the considerations in determining the recoverable amount of the CNS CGU 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.

The accounts receivable financing facility bears interest at c.8.5% of the financed value. The CNS facility limit is US$2.0 million. 80% of 
the eligible accounts receivable balance can be financed. The facility requires a minimum quick asset ratio covenant of 1.15:1 and a 
consolidated quick asset ratio covenant of 2.0:1. The funding is secured by a first lien on the corporate assets of Corero Network 
Security, Inc. and is guaranteed by Corero Network Security plc. 

The carrying value of the financed accounts receivable assets is $0.3 million. All receipts for financed assets are payable to a lockbox 
account held with the provider of the financing facility. The accounts receivable assets are exposed to the risk of non or late payment by 
customers. There are no restrictions on the use of the financed accounts receivable assets.

The fixed term loans were repaid in February 2013 and the 8% loan notes were repaid in October 2013.

At 31 December 2013, the Group’s liabilities have contractual maturities which are summarised below. These contractual maturities

There are no differences between the fair values and book values held by the Group and Company.

The Company has a loan note instrument with CNS, Inc. at 31 December 2013 of $7.4 million (note 16) (2012: $6.9 million). The instrument  
is denominated and repayable in GBP which is the functional currency of the Company and therefore the Company does not bear any 
foreign exchange risk. As the Group’s reporting currency is dollars unrealised gains/losses on translation of the GBP balance are included 
within the Consolidated Statement of Comprehensive Income. A 5% weakening/strengthening of the GBP against the dollar would have 
the effect of increasing/decreasing the Company’s comprehensive income for the year and decreasing/increasing the Company’s net 
assets by $0.4 million. 

The repayment of amounts receivable from subsidiaries, including the loan note from CNS, Inc. (note 16) is dependent on CNS CGU 
generating future revenue growth and cash flows. Note 12 sets out management’s assumptions in assessing whether there is any 
impairment of the CNS CGU goodwill at 31 December 2013. The valuation model concluded that the CGU’s recoverable amount 
exceeded its carrying amount. This assessment supports the carrying value of the amounts receivable from subsidiaries.

Amounts owed by subsidiaries are similarly subject to exchange rate movements. These totalled $10.1 million at 31 December 2013 and 
are included in note 18.

29. Contingent liabilities

The Group and Company do not have any contingent liabilities (2012: $nil).

On 17 March 2011, the Corero Remuneration Committee approved the establishment of the Corero Early Exit Incentive Plan (“EEIP”). 
The EEIP is a cash settled change of control incentive plan for the senior executives of the Group that provides for a cash payment in 
the event of (i) a sale of substantially all of the assets of the Corero Network Security business, or (ii) an offer for all of the shares of 
Corero Network Security plc, in the period up to 30 April 2014 (thereafter it will lapse).

The cash incentive payment is determined based on the difference between (i) the value of the transaction (consideration for the sale of 
all or substantially all of the assets of Corero Network Security, Inc. or offer for all of Corero Network Security plc’s shares) and (ii) 
Corero Network Security plc’s accumulated cost of capital comprising the cash investment by Corero Network Security plc 
shareholders and shares issued for acquisitions or other purposes, defined as the “Total Gain”. The EEIP will pay those executives 
granted the incentive a percentage of the Total Gain. Under the terms of the EEIP, awards up to a maximum of 3.0% of the Total Gain 
can be issued with a maximum of 0.5% per individual.

On 13 September 2013, the Corero Remuneration Committee approved the extension of the EEIP to 30 April 2016 with the awards 
capped at a maximum of 2.5% of the Total Gain with a maximum of 0.65% per individual. 

At 31 December 2013, EEIP awards comprising 2.1% (2012: 1.7%) of the Total Gain had been awarded (including an award of 0.65% to 
Ashley Stephenson and an award of 0.65% to Andrew Miller, both Company directors).

As at the date of this report no discussions are in progress or contemplated which would result in the incentive payment being payable. 
As a result no provision has been recorded in the financial statements relating to the EEIP.

30. Share options

The Company has the following share option schemes:

•    Enterprise Management Incentive Scheme for its employees, which has been approved by HMR&C, 

•    2010 Executive Enterprise Management Incentive Scheme, which has been approved by HMR&C, 

•    2010 Unapproved Share Option Scheme, and

•    Deferred Payment Share Plan.

In August 2010, 1,257,000 options were granted to certain directors and employees under the 2010 Executive Enterprise  
Management Incentive scheme and 2010 Unapproved Share Option Scheme. The options granted vested immediately upon grant.

All other options granted in 2010–2013 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. There are no vesting conditions.

In addition, Andrew Miller has a contractual right (granted in March 2011) to purchase 140,000 ordinary shares in the Company from  
the Employee Share Ownership Trust at 40p per share pursuant to a grant made to him under the Deferred Payment Share Plan.

None of the directors holding office at the balance sheet date exercised options during the year.

Share based payments

The Remuneration Committee can grant options to employees of the Group under the Group’s share option schemes. 

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 Remuneration Committee. The contracted life is ten years from the date of grant. 

Options are valued using the Black-Scholes option-pricing model.

Options granted during 2013

The value of options granted during the year was calculated using the Black-Scholes option pricing model. The following variables and 
ranges were used:

Share price at date of grants 

Exercise price

Expected volatility

Years to maturity

Risk free interest rate

The following table provides information on all options outstanding at the end of the year:

Weighted average remaining contractual life

Annual Report & Accounts for the year ending 31 December 2013

Notice of AGM continued

The following notes explain your general rights as a shareholder and your rights to attend and vote at the AGM or to appoint someone 
else to vote on your behalf:

Notes: 

1. Resolution 9 is to allow the Company to take advantage of the

provisions of the Companies Act 2006 (the “2006 Act”) which enable
companies to communicate electronically or via a website with all
shareholders (including, for example, providing the annual report and
accounts by such means) unless the shareholder asks in writing that he
or she should continue to receive paper documents. Increased use of
electronic communications will deliver savings to the Company in
terms of administration, printing and postage costs as well as speeding
up the provision of information to shareholders. The reduced use of
paper will also have environmental benefits. If this resolution is passed,
we will write to shareholders in accordance with the 2006 Act, inviting
those shareholders who wish to continue to receive hard copy
documents to contact the Company. As this will only take place after
the AGM, shareholders do not need to take any action at present.

2. Pursuant to Regulation 41 of the Uncertificated Securities Regulations
2001 (as amended), only those members registered in the register of
members of the Company at 6.00 p.m. on 16 June 2014 (or if the AGM
is adjourned, on the day which is two business days before the time
fixed for the adjourned AGM) shall be entitled to attend and vote at the
AGM in respect of the number of shares registered in their name at that
time. Any changes to the register of members after such time shall be
disregarded in determining the rights of any person to attend or
vote at the AGM.

3.

Information regarding the general meeting, including information
required by section 311A of the Act, is available from www.corero.com.

4. CREST members who wish to appoint a proxy or proxies through the

CREST electronic proxy appointment service may do so for the AGM to
be held at 9.30 a.m. on 18 June 2014 and any adjournment(s) thereof by
using the procedures described in the CREST Manual (available from
www.euroclear.com). CREST personal members or other CREST
sponsored members, and those CREST members who have appointed
a voting service provider should refer to their CREST sponsors or
voting service provider(s), who will be able to take the appropriate
action on their behalf.

In order for a proxy appointment or instruction made by means of
CREST to be valid, the appropriate CREST message (a “CREST Proxy
Instruction”) must be properly authenticated in accordance with
Euroclear UK & Ireland Limited’s specifications and must contain the
information required for such instructions, as described in the CREST
Manual. The message must be transmitted so as to be received by the
Company’s agent, Capita Asset Services (CREST Participant ID: RA10),
no later than 9.30 a.m. on 16 June 2014. For this purpose, the time of
receipt will be taken to be the time (as determined by the time stamp
applied to the message by the CREST Application Host) from which the
Company’s agent is able to retrieve the message by enquiry to CREST
in the manner prescribed by CREST.

CREST members and, where applicable, their CREST sponsor or voting
service provider should note that Euroclear UK & Ireland Limited does
not make available special procedures in CREST for any particular
messages. Normal system timings and limitations will therefore apply
in relation to the input of CREST Proxy Instructions. It is the
responsibility of the CREST member concerned to take (or, if the
CREST member is a CREST personal member or sponsored member
or has appointed a voting service provider, to procure that his CREST
sponsor or voting service provider takes) such action as shall be
necessary to ensure that a message is transmitted by means of the
CREST system by any particular time. In this connection, CREST
members and, where applicable, their CREST sponsor or voting service
provider are referred in particular to those sections of the CREST

Manual concerning practical limitations of the CREST system  
and timings.

  The Company may treat as invalid a CREST Proxy Instruction in the 
circumstances set out in Regulation 35(5)(a) of the Uncertificated 
Securities Regulations 2001.

5.

If you wish to attend the AGM in person, you should make sure
that you arrive at the venue for the AGM in good time before the
commencement of the meeting. You may be asked to prove your
identity in order to gain admission.

6. A member who is entitled to attend, speak and vote at the AGM
may appoint a proxy to attend, speak and vote instead of him.
A member may appoint more than one proxy provided each proxy
is appointed to exercise rights attached to different shares
(so a member must have more than one share to be able to appoint
more than one proxy). A proxy need not be a member of the Company
but must attend the AGM in order to represent you. A proxy must vote
in accordance with any instructions given by the member by whom the
proxy is appointed. Appointing a proxy will not prevent a member from
attending in person and voting at the AGM (although voting in person at
the AGM will terminate the proxy appointment). A proxy form is
enclosed. The notes to the proxy form include instructions on how to
appoint the Chairman of the AGM or another person as a proxy. You
can only appoint a proxy using the procedures set out in these Notes
and in the notes to the proxy form.

7. To be valid, a proxy form, and the original or duly certified copy of the
power of attorney or other authority (if any) under which it is signed or
authenticated, should reach the Company’s registrar, Capita Asset
Services, PXS, 34 Beckenham Road, Beckenham BR3 4TU, by no later
than 9.30 a.m. on 16 June 2014.

8.

In the case of joint holders of shares, the vote of the first named in the
register of members who tenders a vote, whether in person or by proxy,
shall be accepted to the exclusion of the votes of other joint holders.

9. A member that is a company or other organisation not having a

physical presence cannot attend in person but can appoint someone to
represent it. This can be done in one of two ways: either by the
appointment of a proxy (described in Notes 2 and 4 to 6 above) or of a
corporate representative. Members considering the appointment of a
corporate representative should check their own legal position, the
Company’s articles of association and the relevant provision of the
Companies Act 2006.

In the case of a corporation, the form of proxy must be executed under
its common seal or signed on its behalf by a duly authorised attorney
or duly authorised representative of the corporation.

10. The following documents are available for inspection at the registered
office of the Company during usual business hours on any weekday
(Saturday, Sunday or public holidays excluded) from the date of this
notice until the conclusion of the AGM and will also be available for
inspection at the place of the AGM from 9.00 am on the day of the AGM
until its conclusion:

(a) copies of the executive directors’ service contracts with the

Company and any of its subsidiary undertakings; and

(b) letters of appointment of the non-executive directors.

STRATEGIC REPORT

What  
we do

The Corero First Line of Defense 
products and services stop DDoS 
attacks and cyber threats

OUR TECHNOLOGY

A high performance network appliance which is deployed on premises (at the customer or managed location) or in service provider 
networks. The appliance inspects Internet traffic in real time before it is allowed to pass into the customers protected IT environment  
to ensure unwanted and malicious Internet traffic is removed.

•    The Corero Patented 
Dynamic Threat 
Assessment technology 
uses several algorithms 
including advanced 
challenge-response 
techniques to categorise  
all sources as unknown, 
trusted, suspicious or 
malicious based upon  
their real-time behaviours.

•    The Corero Request/
Response Behaviour 
Analysis controls access  
to downstream devices 
based upon a source’s 
“behaviours” which 
enables enforcement of 
usage standards on every 
source IP address which 
provides detection of 
application-layer denial  
of service attacks, as  
well as other unwanted 
behaviours and blocks 
them before they reach 
the victim devices.

•    The Corero Protocol 

Validation Engines inspects 
all packets of a network 
and/or application 
transaction and compares 
the observed content and 
characteristics to what is 
allowed, expected, or 
required, based upon the 
protocol specifications and 
known implementations, 
and takes the appropriate 
real time actions (e.g. 
detection/blocking) of  
the violations.

•    Corero has a real-time 
reputation engine, 
ReputationWatch, that 
provides automated 
real-time defence against 
previously identified DDoS 
attack sources. In addition, 
IP address geolocation 
technology enables 
enforcement of security 
policies based on national 
origin of IP addresses.

OUR SERVICES

Threat 
Update

Reputation 
Watch

An automated protection update service that provides Corero customers with timely, 
proactive protection from the latest security threats. The subscription service delivers 
frequent protection updates and security advisories. These updates include updated 
vulnerability and attack signatures to provide the most current, effective network threat 
monitoring. Security advisories, an important aspect of the Threat Update Service, 
inform customers of newly discovered threats, and recommend any actions that might  
be necessary to obtain protection against the threat.

Enables customers to automatically block malicious IP addresses. Corero continuously 
receives data feeds from global intelligence across the Internet to determine the current 
threat status of malicious or suspicious IP addresses. Using IP reputation-based 
information, ReputationWatch automatically identifies and blocks access from suspicious 
sites including sources that have participated in DDoS attacks, systems delivering 
specially crafted denial-of-service exploits, anonymized IP addresses behind proxies, 
phishing sites, and spam sources. ReputationWatch also allows customers to block or 
alert on access from countries with which they do not transact business for example by 
choosing to block or set rate limits on all traffic from a nation or geography. 

SecureWatch

A service which ensures that customers’ First Line of Defense solutions are always  
up to date, running at optimum performance, and continuously protecting customers’  
IT infrastructure against the latest threats.

SecureWatch 
Plus

A comprehensive suite of DDoS defence configuration, optimization, 24x7 monitoring  
and attack mitigation services. These services are customised to meet the security 
requirements and business goals of each customer. SecureWatch PLUS includes access 
to experts to assist in the realisation of the desired DDoS defence solution starting with 
the organisation-specific implementation, commissioning and testing, continuing with 
round-the-clock monitoring, and immediate response in the event of a DDoS attack.

Corero is dedicated to improving the 
security of the Internet through the 
deployment of its innovative First Line 
of Defense solutions which provide 
customers with protection against a 
continuously evolving spectrum of 
DDoS attacks and cyber threats that 
have the potential to impact any Internet 
connected business.

The Internet has transformed the way commercial and public sector 
organisations do business
Organisations today are embracing technology to enhance the productivity of their 
employees, generate new revenue sources and improve their operating efficiency.  
These technologies include cloud services, mobile computing, online services and  
social networking. This greater reliance on information technology has significantly 
increased the attack surface within organisations that is vulnerable to potential security 
attacks. As a result organisations are having to make significant investments in IT 
security to help protect against a myriad of potential threats. 

The threat landscape has evolved

“Cyber attacks are one of the top four threats to our national security and cyber-crime  
is costing our economy billions of pounds a year. And as businesses and government 
move more of their operations online, the scope of potential targets will continue to  
grow. It’s a race: to build sufficient cyber defences to match the growing volume and 
dependence of our online economic, security and social interests.” 

UK Cabinet Office Minister, Francis Maude

Cyber-crime continues to be costly

•    The average annualised cost of cyber-crime for organisations is $11.6 million  

per year (an increase of 26% over 2012)

•    Cyber attacks have become common occurrences – two successful attacks  

per company per week (an increase of 18% over 2012)

•    The most costly cyber-crimes are those caused by DDoS, malicious insiders  

and web-based attacks

Source: Ponemon Institute 2013 Cost of Cyber Crime Study

Existing security solutions do not protect against next-generation threats
Though firewalls are still a critical and necessary component of any IT network, they  
are no longer the best type of device to deploy as the network’s first line of defence. 
While firewalls serve many purposes, they do not have complete Layer 3–7 protection. 
Attackers know these limitations and have devised attacks that can evade or overwhelm 
a firewall, as well as the secondary security devices behind the firewall, such as intrusion 
prevention systems. 

The opportunity for Corero
Organisations need to respond to the increased risk presented by the growing number 
of DDoS attacks and cyber threats – a security device specifically designed to detect  
and stop unwanted traffic before it can overrun the IT infrastructure causing performance 
issues, security exposures and even catastrophic outages.

This new first line of defence must be able to identify malicious attack traffic even if it 
mimics legitimate traffic and the true customer communications that businesses want 
and welcome.

The Corero First Line of Defense solution applies industry best practices as well as 
sophisticated analysis techniques to thoroughly inspect traffic in order to stop DDoS 
attacks and cyber threats. The Corero solution stops unwanted traffic that slows the 
infrastructure and frustrates users, and in the process protects the existing infrastructure 
and enables maximum uptime of business applications.

THE COMPETITIVE ENVIRONMENT

Corero is a leader in protecting enterprises and public sector 
organisations against DDoS attacks and cyber threats. We have 
defined the market for on premises First Line of Defense and  
have developed the following key competitive advantages that  
we believe will allow us to extend our leadership position:
•    Always-on protection that blocks both network-layer flooding 
attacks, as well as the more difficult to detect, low and slow 
application-layer attacks.

•    Granular configuration of security policies in order to allow 
legitimate traffic to pass while blocking unwanted traffic.

•    Broad security coverage – Inspection of every packet and  
every flow (using Deep Packet Inspection) rather that a 
sample-based approach used by most competitors. 

•    Purpose-built security appliance for high speed traffic 
inspection using a multi-core processor architecture.

•    Competitive price-performance resulting in the lowest total 

cost of ownership for the end user.

•    Expert security knowledge and technical support provided  

by Corero’s 24x7 Security Operations Centre.

Our next generation product, SmartWall TDS, was launched  
on 3 February 2014 to address the Internet service provider and 
hosting provider markets. It adds key features like asymmetric 
inspection, and multi-tenancy to allow our First Line of Defense 
solutions to be deployed in service provider networks and hosting 
data centers as a services-oriented platform. Service providers 
and hosting providers can now deploy this platform in a modular 
and scalable fashion to not only protect their own infrastructure but 
more importantly to roll out revenue generating DDoS protection 
services to multiple customers. SmartWall TDS extends our current 
competitive advantages with the following key features:

OPPORTUNITIES

The awareness of cyber-crime and the impact on businesses 
(small and large) is increasing with Board room accountability and 
regulatory focus in certain industries, such as financial services. 
We expect this trend to have a positive impact on our market.
Ernst & Young’s Global information Security Survey 2013 reported  
that 50% of respondents indicate that their budgets will increase 
anywhere from 5% to 25% or more in the next 12 months, and  
14% of spend in the coming 12 months will be on security 
innovation (emerging technology).

KEY MARKET CHALLENGES

•    Robust security coverage – comprehensive network  

security protection against layer 3 and layer 4 for both  
IPv4 and IPv6 traffic.

•    Industry-leading density, scalability and performance 

– protection is provided through configurable access policies 
with scalability from 10Gbps to 1Tbps in a single rack.

•    Green, energy-efficient platform – energy-efficient design  
with front-to-back cooling which fully supports economic  
and environmental initiatives.

•    Powerful centralised management for configuring,  

controlling, and monitoring all SmartWall TDS appliances  
from a central location.

•    Flexible deployment configurations – multiple appliances  
can be distributed to key control points in the provider 
network or centrally combined in 1 Rack Unit shelves in 
various configurations.

•    Single solution to deliver comprehensive threat protection, 
always-on connectivity, and complete visibility with the  
family of SmartWall appliances.

The Corero principal competitors are other DDoS defence 
equipment manufacturers such as Arbor Networks Inc.  
and Radware Limited.

Corero is targeting a high growth security market; the DDoS 
market is forecast to grow by 18% (CAGR) in the period 2012  
to 2017 (Source: IDC) to $870 million. The existing Corero  
DDS product is targeted at the enterprise on premises DDoS 
protection market. The new SmartWall™ TDS product is  
targeted at the service provider and hosting provider market.

The market for security products and services is competitive and 
characterised by rapid changes in technology, the evolving cyber 
threat landscape, customer requirements, and industry standards 
and frequent new product introductions and improvements. We 
need to be focused on our chosen market and deliver continuous 

innovation to stay ahead of our competition. Corero will  
address this challenge by working closely with our customers  
and prospects, to leverage the flexibility of our platform 
technology to deliver continuously evolving leadership  
protection against the latest DDoS attacks and cyber threats.

Today’s enterprises are increasingly 
dependent on their online presence for 
generating revenues, ensuring employee 
productivity, or providing a superb 
customer experience. Ubiquitous Internet 
access makes the enterprise susceptible 
to cyber threats from around the world. 
The resulting service outages cause 
costly downtime, lost productivity, brand 
damage and impact the enterprise’s 
legitimate users.
