Aladdin eSafe Attacks Spyware at the Enterprise Gateway With Real-Time Inspection

CHICAGO, December 14, 2004 – Aladdin Knowledge Systems Ltd. (NASDAQ: ALDN) today announced that Aladdin eSafe, a gateway-based, integrated proactive content security solution, now also offers organizations more powerful protection against the fast-growing spyware epidemic.

Spyware intrudes on organizations by tracking browser activity, eavesdropping using keystroke logs and stealing information such as passwords, documents and email addresses. Research firm IDC ranks spyware as the fourth-greatest threat to network security, well ahead of spam and even cyber-terrorism. Spyware is also a growing IT helpdesk concern responsible for numerous calls about mysterious computing symptoms, from a sluggish PC to complete inability to work due to intolerable spyware advertisements and Web page interruptions. To combat this dangerous threat, Aladdin eSafe now offers its customers upgraded spyware protection technology as part of its existing six layers of comprehensive content security. New, four-layer anti-spyware technology within Aladdin eSafe includes:

Spyware download blocking – Spyware exploits’ automatic downloads are proactively blocked. eSafe also limits access to spyware download servers through URL blocking.
Spyware ID blocking – The ability to identify spyware by its unique installation identifiers and other parameters, also effective against other malicious mobile code. This allows the creation of white and black lists of objects.
Spyware signature blocking – Regular signatures along with heuristics-based smart signatures block most spyware. This fights spyware worms traveling by email or downloaded from Web and FTP sites.
Spyware communications blocking – Aladdin eSafe’s unique AppliFilterâ„? technology prevents existing spyware from communicating with their server, rendering spyware useless to the vendor. This also allows administrators to easily identify infected machines and recognize spyware communications on any port.

When new spyware is discovered, eSafe signatures and spyware attack parameters are automatically updated by the Aladdin eSafe CSRT (Content Security Response Team). Automatic updates include spyware and malicious code signatures, spyware and malicious code proactive heuristics definitions, spyware and legitimate ID definitions and AppliFilterâ„? real-time spyware protocol definitions.

“No one likes to be watched without knowing it, especially large organizations. Aladdin eSafe’s newest spyware protection gives IT administrators the ability to easily and consistently block one of the Internet’s fastest growing threats,” said Shimon Gruper, vice president of technologies for the Aladdin eSafe Business Unit. “Combined with eSafe’s six comprehensive content security layers, our spyware protection provides unparalleled defenses against malicious code and the loss of valuable intellectual property.”
