Boston Celtics Select Aladdin eSafe for Powerful Anti-Virus, Web Security and Spyware Protection

CHICAGO, March 21, 2005 - Aladdin Knowledge Systems Ltd. (NASDAQ: ALDN) today announced that the Boston Celtics basketball franchise chose Aladdin eSafe, the ultimate gateway-based security solution offering six comprehensive layers of content security that protect the team's entire administration from ever-growing Internet threats.

Known for dominating the NBA from 1957 to 1969 when they won 11 NBA Championships, the Boston Celtics hang more title banners from the rafters of their home arena than any other franchise. A charter member of the Basketball Association of America (which evolved into the NBA), the Boston Celtics now include an extensive staff roster in need of uninterrupted, safe Internet access around the clock. The team's IT staff wanted to replace and consolidate its existing security tools into one comprehensive solution designed for powerful protection, yet streamlined management.

Using unique technologies not found in competing products, Aladdin eSafe provides the Boston Celtics with protection against known viruses as well as unknown or potential viruses that have not yet hit the Web. In addition to this valuable protection, Aladdin eSafe also provides unique application-level gateway filtering with eSafe AppliFilter™, an Advanced Anti-Spam Module and powerful anti-spyware protection. "Aladdin's eSafe plays an integral role in our Network Security Infrastructure," said Jay Wessel, senior director of technology for the Celtics. "The ability to stop so many types of threats in one easily managed appliance makes eSafe a slam dunk."

"The Celtics are free to focus on enhancing their game while gaining peace of mind that their IT resources are not affected by ever-increasing, dangerous Web content," said Shimon Gruper, vice president of technologies for the Aladdin eSafe Business Unit. "Easily managing multiple layers of content security, Aladdin eSafe is trusted by the Celtics' IT staff to protect their entire administration while the team is both off and on the court."
