ADVANCE INFORMATION ON THE NET SALES OF THIRD QUARTER. ESTIMATE OF THE NET SALES
AND OPERATING PROFIT FOR THE FULL YEAR IS CHANGED

Stonesoft Corporation's product sales for the third quarter were approximately
5.6 million euros and grew by approximately 18%. The net sales for the quarter
were about 9.2 - 9.3 million euros, equaling 14-16% growth. The growth was lower
than expected because of postponed purchase decisions by some clients.

Earlier the company has announced that Stonesoft aims net sales to grow by at
least 30% and to achieve a positive result for the year 2012.

Based on the current outlook the company expects the net sales to grow by 25 -
32 % in 2012 and the full year operating result (EBIT) to be close to zero.

The presented advance information is unaudited and it is not based on an interim
report approved by the Board of Directors.

Stonesoft Corporation will issue its interim report for January - September
2012 as previously announced on Friday, October 19, 2012. A press conference for
the media, analysts and investors will be held on October 19, 2012 at 10:30 am
