Sourcefire Announces Immunet 3.0

PRESS RELEASE

Columbia, MD – February 09, 2011 -- Sourcefire, Inc. (Nasdaq: FIRE), the creator of Snort' and a leader in intelligent cybersecurity solutions, today announced the availability of ImmunetTM 3.0, which leverages a cloud-based collective immunity platform to deliver real-time protection against zero-day attacks. Immunet 3.0 enables businesses and consumers to create custom anti-malware signatures for more accurate protection against targeted attacks and offers an innovative Cloud RecallTM feature, which can remediate previously approved files, automatically quarantining them in real time based on new threat information.

“Immunet 3.0 changes the way anti-malware works. By leveraging the cloud and allowing users to create custom signatures, Sourcefire is increasing the speed and accuracy of its protection to align with the demands of today’s environments,” said Charles Kolodgy, research Vice president at IDC. “With the added ability to protect against malware introduced by non-traditional means, including rootkits and USB drives, Immunet 3.0 is offering customers the functionality they require, while filling significant holes that have been left by more traditional solutions.”

Backed by the additional resources of Sourcefire', Immunet 3.0 offers significant advancements that enable consumers and businesses to protect their PCs from Client-Side attacks. These include:

* Custom Signature Creation – While customization is available in some enterprise security solutions, including Intrusion Prevention Systems, traditional antivirus offerings continue to take a “black box” mentality to customization. With Immunet 3.0, customers now have the power to create signatures for their specific requirements, significantly improving the effectiveness of Immunet.

>> Cloud Recall – This new, innovative feature leverages the power of the Immunet platform to provide increased endpoint protection. Through continuous file processing in the cloud, Immunet 3.0 can retroactively quarantine a file that was originally cleared, but later deemed to be malware. The Immunet Community is updated automatically as new threats are discovered. Cloud Recall provides a significant advantage over traditional approaches to solving this problem, which include sending 20,000 - 40,000 signatures down to each and every endpoint on a daily basis, then invoking a resource-intensive full system scan.

>> Collective ImmunityTM – A key benefit of Immunet 3.0 is Collective Immunity, which allows users to harness the collective presence of Immunet’s 850,000 worldwide users for increased endpoint protection. This cloud-based approach enables organizations to better protect against zero-day attacks with real-time protection driven by intelligence from the user community. Each time someone in this collective community encounters a threat, everyone else in the community automatically gains protection from that same threat in real time. Customers no longer have to rely on the isolated security of their traditional antivirus vendor.

Because Immunet offers users an extremely light client, it is ideal for individual consumers and organizations looking to enhance their current anti-malware protection with a companion solution. Removing previous limitations for multiple anti-malware solutions residing on a single system, Immunet enables users and organizations to simultaneously run multiple solutions, without the risk of system conflicts, for defense-in-depth protection.

“When it comes to protecting against new and targeted threats, traditional anti-malware solutions typically fall short because of the time it takes to push new signatures,” said Martin Roesch, Sourcefire’s CTO and Founder. “Sourcefire’s approach is revolutionizing the way consumers and organizations protect their endpoints. By leveraging our innovative cloud platform and enabling customers to create custom signatures, Immunet 3.0 is offering consumers and businesses the ability to take a more proactive stance with their anti-malware investments and better protect against the latest attacks that traditional solutions miss.”
