Aladdin Discovers and Implements Generic Gateway Protection Against Microsoft Outlook Hostile Exploits.

Business Editors, Hi-Tech Writers

CHICAGO--(BUSINESS WIRE)--July 26, 2000

eSafe Gateway grows even stronger with the addition of yet another

generic solution against digital threats

Aladdin Knowledge Systems (NASDAQ: ALDN), a global leader in the field of Internet content and software security, has announced its eSafe Gateway Internet security solution now protects against Microsoft Outlook's recently detected hostile exploit.

Although a Microsoft patch has been issued to solve the security breach, the solution is limited to the desktop. Due to time constraints and the complexity of providing a patch for each desktop in a network environment, eSafe Gateway's protection is a simple, yet effective proactive solution.

"The gateway solution that Aladdin offers today provides large networks with the ability to effectively implement a solution in a timely fashion, when time is of the essence. Being able to block hostile exploits at the gateway provides excellent coverage for this type of breach. Aladdin is to be commended for taking the next step by providing this solution," said Peter Tippett, Chief Technologist, ICSA.net.

As part of new HeaderVerify (TM) technology, eSafe Gateway blocks any malicious email that attempts to use such an exploit. With Aladdin's eSafe Gateway in place, there is no longer a need for each PC in an organization to individually install a patch. Expecting network administrators to deploy large-scale upgrades and patches to each PC is neither timely nor efficient. Instead, eSafe halts the malicious email at the gateway level. Stopping this email at the gateway prevents the exploit from being used by a hacker, who would attempt to send an email with a corrupt header. Causing a buffer overrun, the corrupt header could initiate a Denial of Service (DoS) attack or even run arbitrary code that can result in trojans, viruses, etc.

"This exploit is not a virus, nor can the proper protection be gained through conventional virus-preventing methods," said Shimon Gruper, Aladdin's Executive Vice President of Internet Technologies. "Aladdin's Proactive Protection through eSafe Gateway is a comprehensive solution above and beyond this one particular exploit issue. Our all-encompassing gateway solution is part of our new HeaderVerify (TM) system designed to prevent spam, spoof, relay and other email exploits. eSafe Gateway's protection is quick and effective, keeping just as up-to-date as the threat itself."
