the result for the year 2009, but has now given an estimate of the
net sales for the full year.

CEO Ilkka Hiidenheimo

The comparable operating result and net sales of the company almost
reached the level of the corresponding period in the previous year,
despite the general market situation.

In our main market area, Europe, the sales of the StoneGate product
family stayed on an adequate level. However, the sales in America and
Russia did not meet the expectations. In the Emerging Markets, which
have grown strongly during the previous years, especially North
Africa showed positive development developed positively. We renewed
the partnership contract entered in the previous year with the
leading national telecommunications company by a frame agreement,
with first orders related to it at the value of EUR 1.2 million. The
deliveries took place during the second quarter of the year. The
orders further strengthen our position in North Africa.

To reach our target for the rest of the year, we reduced the
company's cost structure and commenced co-operation negotiations,
based on which the company decided to terminate the employment
contract of six (6) employees and lay off the personnel in Finland
with certain exceptions for six weeks in stages during the rest of
the year.

Tekes, the Finnish Funding Agency for Technology and Innovation, has
decided to fund Stonesoft Corporation's research and development
project "The protection of fast networks of critical infrastructure"
with more than a million Euros in 2009 and 2010. The funding decision
considerably accelerates the completion of the project, which in turn
clearly improves the competitiveness of our products. The project has
significant novelty value and is highly challenging in international
framework.

The StoneGate 5.0 launched in April has been received positively in
the market. With the unified management offered by our products, our
customers have been able to increase the efficiency of their
operations and gained significant cost savings. After the reporting
period we launched the high performance network security appliances
FW-5105 and IPS-6105, which extend our product offering to the high
capacity network environments of large enterprises and telecom
operators. The first deliveries to customers have already been made.

The relative importance of the operationality and availability of
data networks to business is continuously increasing. This had led to
the growth of the demands to network security design and to the need
to achieve a comprehensive overview of the state of the network and
data communications. We are specialized in delivering comprehensive
network security solutions, which meet also the exceptionally high
demands of critical network environments and enable increased
efficiency and flexibility.

Based on the authorization, the Board of Directors may decide to
issue new shares for subscription according to the shareholders'
pre-emptive subscription rights or in deviation from the
shareholders' pre-emptive subscription right, or in a directed issue
of option rights or other special rights in case the deviation is

incentive to the company's personnel.

The issue may be directed in whole or in part to the main
shareholders of the company Ilkka Hiidenheimo and Hannu Turunen, who

CORPORATE GOVERNANCE

Stonesoft complies with the Corporate Governance Recommendations for
listed companies issued by the Confederation of Finnish Industries EK
the NASDAQ OMX Helsinki Ltd and the Central Chamber of Commerce in
October 2008, as described on the web pages of the company.


RISKS AND BUSINESS UNCERTAINTIES IN THE NEAR FUTURE

In the current fiscal period, Stonesoft's main risks and business
uncertainties relate to the realization timetable of the sales
projects and possible productions disruption of our subcontractors
and suppliers. In addition to these factors, the general economical
uncertainty that has previously grown strongly, remains a risk
factor, but seems to be somewhat stabilizing. Otherwise there have
been no significant changes in Stonesoft's uncertainties in
comparison to the risks and business uncertainties that have been
announced earlier.

FUTURE OUTLOOK

Companies will continue to network with their partners and
subcontractors, and this development will create even higher
requirements for network security and availability. At the same time,
the demand for outsourcing solutions and services will grow. Managed
Security Service Providers (MSSPs) have a growing need to provide
their customers with the possibility to track the status of their
network security while maintaining an overview of their own data
network. According to the company's view combining security and high
availability, which is the cornerstone of StoneGate product design,
will prove its strength even better in this development.

The convergence of voice, video and data on IP-based networks will
create more demand for capacity and drive the adoption of 10 Gbps
networks. The growing demand for added bandwidth together with new
protocols in the IP networks is expected to increase the general
demand for better reporting, monitoring and analysis tools. This
development will support Stonesoft in achieving its year 2009 growth
plan, since these are the cornerstones in StoneGate Management
Center's functionality.

The strong growth of virtualization has created a demand for ensuring
network security and business continuity also in virtual
environments. StoneGate products are better suited for virtual
environments than the competitors' products because they are based on
software solutions.

As security threats in the public sector increase, growing number of
government organizations have started improving their protection
against network attacks and cyber espionage. StoneGate products offer
comprehensive, centrally managed protection and suit well to the
needs of the public sector.

While the global financial uncertainty continues, companies need to
pay attention to the cost efficiency of their operations. This will
further strengthen the competitiveness of the StoneGate solutions and
emphasize the possibilities the solutions offer for generating
considerable cost savings in relation to infrastructure,
communications and operating costs.

Due to the general economical situation and prevailing global
uncertainty, it is difficult to give any estimates on the future
development. Based on this, the company still does not regard it
justified to give any estimate on the future development of the
result in 2009, although it strives for an improved operating result
(EBIT) compared to the previous year. Based on the existing sales
pipeline and the already realised net sales, the company expects the
net sales for the full year to remain at the previous year's level.
The net sales are expected to be at EUR 24.3 million, +/- EUR 1.5
million.

With regard to the development of the turnover and the operating
result, variation is expected between the quarters in comparison to
the corresponding quarter during the previous year as well as to the
previous quarter as a consequence of, among others, long sales
cycles, a relatively big impact of individual deals, and the
variation between the quarters in the previous year.
