Third Brigade Host Intrusion Prevention System Delivers Protection for Microsoft Windows Vista(TM).

Product Architecture Provides Rapid Support to New Operating System Versions

RESTON, Va. -- Third Brigade (www.thirdbrigade.com), a security software company that specializes in host-based intrusion prevention systems, announced that Third Brigade Deep Security supports the Microsoft Windows Vista operating system.

However, Third Brigade Deep Security has been architected to protect multiple platforms, and primarily uses deep packet inspection to protect vulnerabilities. This allows us to quickly support new operating system versions, and ensures that our host intrusion prevention system is not a barrier to customer deployments of new platform versions.

Microsoft Windows Vista is the latest operating system version from Microsoft and will be followed in 2007 with Microsoft Windows Server "Longhorn." Significant security enhancements have been added to Windows Vista and complement the protection provided by Third Brigade Deep Security. Windows Vista and Windows Server "Longhorn" 64-bit versions include PatchGuard, a kernel protection mechanism that is problematic for some security vendor implementations (see Gartner research note G00144225, "Microsoft's Windows PatchGuard Changes Will Take Years"). PatchGuard has no impact on Third Brigade Deep Security, which uses published APIs as the method to provide additional protection for Microsoft platforms.

"Some host intrusion prevention vendors have platform compatibility issues with the kernel hooking approach they use," said Brian O'Higgins of Third Brigade. "However, Third Brigade Deep Security has been architected to protect multiple platforms, and primarily uses deep packet inspection to protect vulnerabilities. This allows us to quickly support new operating system versions, and ensures that our host intrusion prevention system is not a barrier to customer deployments of new platform versions."

Third Brigade Deep Security provides protection for a broad set of platforms, including Windows, Linux and Solaris operating systems, as well as the applications that run on them. Third Brigade Deep Security supports Microsoft Windows Vista (32-bit) today, and support for 64-bit versions of Microsoft platforms will be available in early 2007.

Third Brigade's host intrusion prevention system uses deep packet inspection to detect and prevent known and zero-day attacks. And by combining a software firewall with host-based intrusion detection and prevention, it dramatically reduces false positives and negatives.
