basketball franchise
chose Aladdin eSafe, the ultimate

than any other franchise.
A charter member of the Basketball Association of America (which evolved

Advanced Anti-Spam Module and
powerful anti-spyware protection.

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.”

peace of mind that their IT
resources are not affected by ever-increasing, dangerous Web content,”
said Shimon Gruper, vice
