ADVANCE INFORMATION ON THE NET SALES AND OPERATING PROFIT OF SECOND QUARTER

Stonesoft expects the net sales for the second quarter of 2010 to decline by
about 15% compared to the corresponding period in the previous year and expects
the operating result to be negative.

The net sales and operating result have been affected by the postponement of
customers' purchase decisions while economic uncertainty has increased. In
addition, the deliveries of some large orders have moved to the third quarter
due to the time required by the delivery process. Also some of the received
orders have not been deliverable during the second quarter because of delivery
difficulties of the new appliances."Stonesoft has continued to invest in new, significant customer accounts and
business opportunities in a long-standing way. The growth of net sales and
operating result brought by these will become visible during the second half of
the year. The sales pipeline of the second half of the year 2010 is strong and
has developed positively", said Ilkka Hiidenheimo, CEO of Stonesoft.

Stonesoft maintains its full year estimate regarding the net sales and operating
result for now and still expects its net sales to grow from the previous year's
level and the result to be positive.

Stonesoft's Interim Report for the second quarter of 2010 will be published on
13 August 2010.
