San Diego, CA, February 17, 2009, St. Bernard Software, Inc. (OTCBB: SBSW), a leader in Web security appliances, today announced the availability of multi-layer anonymizer protection in its iPrism Web Filter. Organizations can now benefit from iPrism's unique two-layer anonymizer defense, which detects and guards against Web-based proxy servers, prevents security exploits and ensures users can't circumvent filtering technologies.

Web-based proxies are an increasingly popular threat and pose a significant risk to both the network and the user, which can result in costly violations of acceptable usage policies. St. Bernard's new anonymizer defense helps effectively detect and block Web-based anonymous proxies though a multi-layer defense. This includes a unique combination of URL-based and proxy pattern-based blocking backed by St. Bernard's iGuard URL classification team. The iGuard team provides a 100% human review and rating of its URL database, which is updated daily so iPrism can identify and block requests for anonymous proxies instantly.

As an added layer of protection, iPrism detects and blocks all uncategorized sites based on the signature file in the iGuard database, immediately identifying new proxy sites. This pattern-based blocking allows iPrism to recognize attempts to establish proxy tunnels, intercept any connections from taking place and document efforts to circumvent the filtering technology in its reports.

In addition to its multi-layer approach, iPrism's powerful anonymizer defense also features:

Spoofed SSL: Detects and blocks anonymizer traffic that attempts to spoof secure traffic Dynamic proxy detection: Allows administrators to track proxies such as UltraSurf, Google-Web-accelerator and http-proxy domains Real-time updates: Monitors for new anonymizers daily and collects proxy URLs, reporting results to the 100% human-reviewed iGuard database to verify pre-qualified Web sites Active domain IP address mapping: Cross-references IP addresses to their corresponding domain, further prohibiting access to illicit sites Concealed surfing: Reports Web activity by tracking domain names instead of IP addresses

"We noticed a growing trend among students utilizing anonymizers as a way of bypassing filtering policies," said Larry Seely, IT Director at Cornelia Connelly High School. "iPrism's anonymizer defense automatically provides the most up-to-date protection against these sites, alleviating the burden on IT to manually lock this down. St. Bernard's iPrism provides a comprehensive Web filtering solution that tackles this challenge, and helps us maintain the educational value of our resources while keeping our network secure."

"With its multiple layers of protection, iPrism's anonymizer defense provides continual, real-time protection against threats to established acceptable use policies from Web proxies," said Ron Kaplan, senior director of product management at St. Bernard. "Not only does our new anonymizer protection enhance the value and performance of our leading filtering technology, but it also provides our customers with a simple, comprehensive solution for addressing any proxy exploit while securing their networks. "

iPrism comes equipped with high-performance anti-virus and anti-spyware as standard features, protecting networks from the dangers of contaminated Web sites. The iPrism appliance also utilizes deep packet inspection technology to analyze Web traffic, identify suspicious activity and block access to sites accordingly.
