PRESS RELEASE

COLUMBIA, Md. & PALO ALTO, Calif. --(Business Wire)-- Mar 02, 2010 Sourcefire, Inc. (Nasdaq:FIRE), the creators of SNORT' and a leader in intelligent Cybersecurity solutions, and Immunet, the developer of next generation antivirus technologies, today announced a partnership to deliver a free, Windows-based version of the ClamAV' antivirus solution. The new ClamAV for Windows leverages Immunet's Cloud-based Collective Immunity technology, linking together a user's network of friends to identify new threats in real-time, providing instant protection across the product's user-base.

"An estimated 50 percent of Internet connected PCs have inadequate or expired antivirus protection which leaves a sizable, and often unrecognized, vulnerability to malicious code. By partnering with Sourcefire we're able to bring real-time protection to the large ClamAV user-base and protect customers more effectively than traditional solutions," said Alfred Huger, Vice President at Immunet. "The two technologies are naturally complementary. By adding the leading capabilities of ClamAV to the Immunet Cloud, we add an additional layer of protection, enhancing Immunet's breadth and depth of threat coverage."

Through Collective Immunity, ClamAV for Windows users are able to link to a global community, including their friends, family and colleagues to harness a collective knowledge-base for securing their PC. Every time someone in this community encounters a threat, all global ClamAV users gain protection instantly. ClamAV for Windows can be used as a stand-alone, host-based antivirus solution or in conjunction with a pre-installed solution to provide enhanced detection for the latest malware threats. The ultra-light footprint allows PC resources such as memory and processing power to be used for other more critical applications.

"ClamAV is one of the most widely deployed open source anti-malware solutions in the industry, powering numerous security solutions worldwide. The relationship with Immunet takes ClamAV's protection a step further," said Matt Watchinski, Senior Director of the Sourcefire Vulnerability Research Team. "Immunet's unique, cloud-based approach provides consumers with a new method for protecting against threats. By using ClamAV for Windows, customers have the confidence that they are receiving the same level of security as many global enterprises."

Immunet has placed ClamAV into its Cloud infrastructure alongside a number of other detection technologies. By combining these technologies, and using the power of community-based protection, Immunet offers one of the most highly effective antivirus technologies on the market.

ClamAV is one of the most commonly used open source anti-malware solutions in the world with over two million gateway devices downloading updates daily from 121 mirror servers located in 43 countries. Renowned for its speed and accuracy, ClamAV has been adopted by network security vendors and managed security service providers worldwide to identify deeply embedded threats such as viruses, trojans, phishing and other forms of malware. One of ClamAV's key benefits is that it incorporates both heuristics and signatures to deliver leading detection of known malware threats. In addition to the rapid innovation of its anti-malware detection engine, the ClamAV team and user community deliver daily updates to the ever-growing virus database of over 700,000 signatures.
