St. Bernard Security Update for July Reveals That Two-Thirds of All Email Was Blocked Based on Sender Reputation

On-Demand Email Filtering Solution Blocks PDF Spam and Other Emerging Threats Without Relying on Message Analysis


SAN DIEGO, CA--(Marketwire - August 6, 2007) - St. Bernard Software, Inc. (OTCBB: SBSW), a global provider of security appliances and on-demand solutions, including secure content management, archiving and collaboration, today announced that its on-demand email filtering solution, LivePrism, blocked two-thirds of its customers' incoming email in July based solely on sender reputation without having to analyze the message content. This provides an increased level of protection against evolving threats such as image spam and PDF spam. In total, St. Bernard blocked 89 per cent of customers' incoming email for being spam or virus infected.

St. Bernard's partner Commtouch released its 'Email Threats Trend Report' for the second quarter of 2007, based on the company's real-time analysis of billions of e-mail messages globally each week. Highlights of this report included:

--  Spam with PDF attachments emerged as spammers' newest technique for
    avoiding detection at the end of the second quarter of 2007.
--  During one massive attack, PDF-spam comprised 10-15 per cent of global
    spam messages during a 24-hour period, increasing overall global spam
    traffic by 30-40 per cent.(1)
    

"The popularity and frequent use of PDFs for legitimate business communications makes it difficult for traditional spam filters to effectively block these messages," said Andrew Lochart, vice president of marketing at St. Bernard. "The ability of St. Bernard's LivePrism to block these spam tactics without having to rely on message content analysis helps provide our customers the protection they need."
