Aladdin eSafe Receives Checkmark Spyware Certification

CHICAGO, September 21, 2005 - Aladdin Knowledge Systems (Nasdaq:ALDN), the worldwide leader in Software Digital Rights Management (DRM) and USB-based authentication solutions, and a leading innovator in enterprise secure content management, today announced that the Aladdin eSafe integrated gateway content security solution recently received Checkmark Spyware certification through West Coast Labs, a leading independent testing organization for information security products.

Illustrating the importance of the recent Checkmark certification, a recent Aladdin eSafe Content Security Response Team (CSRT) study found that a staggering 15 percent of spyware threats actually steal passwords and log keystrokes. The study shows that a growing amount of spyware is specifically designed for identity theft and continues to compromise both personal and commercial privacy.

Aladdin eSafe is the industry's first gateway solution featuring four layers of spyware protection. Designed to effectively fight the ever-increasing spyware epidemic, Aladdin eSafe goes beyond blocking spyware by URL, signature or other singular methods. Instead, eSafe uniquely hits spyware head on throughout each stage.

"For a product to be certified to the Spyware Checkmark standard, the product must be able to detect, without causing false alarms, all Spyware samples in the West Coast Labs test suite -- which includes a variety of backdoors, down loaders, exploits, proxies, RATs, password stealers, crackers, hijackers, financials and stealers," said Jon Stearn, CTO for West Coast Labs.

"Spyware writers are constantly seeking new ways to penetrate and silently infect users' computers," said Shimon Gruper, vice president of technology for the Aladdin eSafe Business Unit. "This is why multilayered, proactive protection technology, such as Aladdin eSafe, is required to effectively thwart this constantly evolving spyware threat. We are proud that the effectiveness of our technology was acknowledged by Check Mark Certification."
