Ottawa, ON and Reston, VA September 2, 2008 -- Third Brigade, a security software company specializing in host intrusion detection and prevention systems (IDS/IPS), today announced that NSS Labs, a world leader in independent security product testing and certification, has extended its PCI Suitability validation of Third Brigade Deep Security to include protection of Linux, Solaris and Windows-based servers. The evaluations concluded that Third Brigade Deep Security delivers an excellent level of protection, blocking 100% of live attacker initiated exploits attempted on numerous operating systems and applications across these three server platforms.

"Deep Security should be on any short list as a candidate for deployment in the corporate perimeter, e-commerce datacenter, internal datacenter, or on back-end servers in large retail storefront environments," said Rick Moy, President of NSS Labs. "This powerful and flexible tool excelled throughout our comprehensive testing in our real-world test lab."

"Large retailers are looking for ways to simplify their security requirements, particularly at the storefront where hardware solutions are just too costly to deploy," said Wael Mohamed, President and CEO, Third Brigade. "NSS Labs has validated that Deep Security delivers unmatched security to payment card environments, across more server platforms, making Third Brigade an even more attractive and cost-effective alternative for storefront server protection."

The NSS Labs PCI Suitability reports provide empirically validated evidence about a product's suitability for use in a payment card network. NSS Labs performed rigorous and comprehensive testing of Third Brigade Deep Security to verify the ability of the software to mitigate unauthorized system activities including: network exploits targeting vulnerable services, localized privilege escalation / "root kits", unauthorized access to internal operating system resources, and modifications to key operating system files and configuration data; while processing legitimate applications and servicing legitimate network requests.

Third Brigade is the first host intrusion prevention system to complete NSS Labs' suitability testing for use in merchant environments across the following server platforms:

• Sun Microsystems Solaris™ v8, v9 (Sparc) and Solaris™ 10 (x86)
• Red Hat® Enterprise Linux® Server v3, v4, and v5, (32-bit)
• SUSE Linux Enterprise Server v9 and v10
• Microsoft® Windows® Server 2003
