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&#153, 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.”
