SUNNYVALE, Calif., June 22, 2005 - Fortinet - the pioneer and market leader of Unified Threat Management and only provider of ASIC-accelerated, network-based antivirus firewall systems for real-time network protection-- today announced its entry into the top five ranking of security appliance vendors in Western Europe, with Cisco, Nokia and Juniper and ahead of Symantec, based on revenue generated in the first quarter of 2005. According to new statistics released from leading global market research firm IDC in its 1Q05 European Quarterly Security Server Appliance Tracker, Fortinet exhibited the strongest annual revenue growth of the top-five ranked vendors in 1Q05, demonstrating an increase of 160 percent (1Q05/1Q04). Fortinet was also the top-ranked revenue vendor in the Western European Unified Threat Management (UTM) category for the quarter, with 17 percent of total market share.

Fortinet is the pioneer of the UTM market place, offering its best-in-class security applications -- which include firewall, antivirus, virtual private network (VPN), intrusion prevention (IPS), antispam, Web content filtering and traffic shaping -- individually, or combined as a UTM solution. First introduced in 2002, Fortinet's FortiGate™ systems have since gained widespread market adoption, with nearly 90,000 units installed worldwide, leading to the strong revenue growth shown in this IDC research.

Oliver Harcourt, senior research analyst for IDC's European Enterprise Server Solutions research team said, "This latest report shows a healthy growth in the UTM security appliance sector, reinforcing IDC's belief that by 2008, UTM appliances will dominate the security appliance market. Data from our European Quarterly Security Server Appliance Tracker shows that Fortinet held the greatest share of this market in the first quarter, in addition to the number four ranking in Europe's total security appliance market."

"Fortinet has made considerable inroads into the security appliance market place within a very short time,"said Andre Stewart, Fortinet's vice president of sales, EMEA. "The annual revenue growth confirmed by this latest IDC report shows how companies of all sizes have been quick to realize the benefits of Fortinet's FortiGate platform, placing us amongst the leading security vendors today. We believe this strong growth rate will continue and look forward to taking an even more prominent position within the top revenue rankings over the next quarters."
