Aladdin and Crossbeam Systems Partner to Offer Powerful Content Security for High Capacity and High Availability Customers

CHICAGO, April 28, 2004 – Aladdin Knowledge Systems, Inc. (NASDAQ: ALDN) and Crossbeam Systems, Inc., a leading global developer of total security solutions, today announced a partnership that will bring high performance content security to enterprise networks as part of a comprehensive, multi-application security solution. Under the agreement, the Aladdin eSafe? integrated content security solution is now offered on all Crossbeam X-Series and C-Series security services switches.
Allowing Crossbeam customers to easily deploy both solutions, the Aladdin-Crossbeam partnership integrates eSafe with the C-Series, the industry’s first stackable security services switch, and the X-Series, a family of flexible, high performance, high availability security services switches developed to meet the varied security and infrastructure requirements of today’s organizations. Crossbeam’s patent-pending architecture integrates best of breed security engines (firewall/VPN, intrusion prevention and protection, content security and web filtering) into high performance, highly available security services switches designed for both enterprise and service provider networks.

“Many companies do not scan HTTP traffic because of poor performance, resulting in a significant hole in network security for malicious code,” said Joel Silberman, vice president of ISV partnerships and business development for Crossbeam Systems. “This partnership with Aladdin delivers high-performance, multi-layered content security to stop both known and unknown threats and provides further evidence of Crossbeam’s leadership in offering its customers a broad range of best-of-breed security applications.”
