PRESS RELEASES

SUNNYVALE, Calif., December 4, 2007 -Blue Coat Systems (Nasdaq: BCSI), a leader in WAN Application Delivery and Secure Web Gateway, today announced that its award-winning K9 Web Protection Internet filtering software now offers real-time phishing protection against online fraud, thievery and identity theft. K9 Web Protection now incorporates the same Blue Coat Real-Time Anti-Phishing protection technology recently introduced in Blue Coat's enterprise-class WebFilter^TM product, making it the first consumer Internet filtering software that can warn users about brand new or previously undiscovered phishing Websites by using a real-time rating capability.

"K9 Web Protection saved me yet again," wrote Joel Boucree, a K9 Web Protection user, in a note to Blue Coat. "I received a phishing email that told me I needed to confirm my email address on Amazon.com. It looked authentic so I figured I'd give it a try. K9 blocked the phishing site dead in its tracks. I've also noticed it works to block phishing traps accessed through use of the MySpace Web site. . . I've recommended your software countless times and will continue to do so."

Phishing, the practice of luring an unsuspecting person to a counterfeit Website that resembles a legitimate site and tricks the user to reveal logins, passwords, credit card information and other private information, has resulted in a growing amount of identity theft, robbery and fraud. According to industry researchers, the average losses from phishing are now over $3,000 per incident and the total damages suffered by users victimized by phishing are well over $1 billion per year. Banking and retail sites, including Amazon.com, Ebay and PayPal, have been some of the most popular for criminals to impersonate through counterfeit sites using phishing schemes. Social networking sites, such as MySpace and Facebook, are also key targets for ‘social phishing' since personal details published on such sites can be used in identity theft. Experiments conducted at Indiana University show a success rate of over 70 percent for phishing attacks on social networks [source: "Social Phishing," Tom Jagatic, Nathaniel Johnson, Markus Jakobsson, and Filippo Menczer, School of Informatics, Indiana University, Bloomington].

The Blue Coat Real-Time Anti-Phishing protection technology assesses the Web page being requested as the user clicks on the link. If the page is not found in the database, a query is sent to a data center in Blue Coat Labs where the Web page is analyzed automatically in real time. The service will then categorize the page. If the Web page is categorized as a phishing site, the K9 Web Protection software will block the requested Web page or warn the user. The entire process can be completed in between 250-750 milliseconds.

"A majority of first generation Internet parents are still getting up to speed on today's basic online technology and lack experience in dealing with deeper concerns such as phishing and identity theft," said John Carosella, vice president of strategy and outreach, Blue Coat Systems. "The Internet is constantly evolving. K9 Web Protection helps parents stay a step ahead of the harmful content and malicious scams that social networking vehicles, email and Web content bring into the home. Adding anti-phishing capability to K9 Web Protection comes at a critical time as parents gear up for holiday purchases that include desktop and laptop computers."

Designed for parents, K9 Web Protection implements the same Web filtering technology used by Blue Coat enterprise and government customers worldwide. K9 Web Protection divides the Internet into 60 categories, and relies on Blue Coat's commercial filtering service that processes 80 million Web site rating requests per day. Parents can configure the software to block or allow content from specific categories such as pornography, spyware, and adult/mature content, and can also block access to the web at selected times of day-after bedtime, for example. K9 Web Protection is available at no charge through the Blue Coat Community Outreach Program (www.k9webprotection.com), which also provides materials and resources to educate Internet parents about the impact of the Internet on children and on parenting strategies.
