CYRN CYREN Ltd

Bizanga and Commtouch(R) (NASDAQ:CTCH) today announced the integration of Commtouch's real-time virus and spam protection technology into Bizanga's Intelligent Message Processor(TM) (IMP). This move is expected to provide enhanced email defense options to Bizanga's service provider and operator customers. The Commtouch anti-spam and Zero-Hour(TM) virus prevention technology joins other best-of-breed filtering technologies available on the IMP to provide rapid response capabilities to operators and service providers. Commtouch's Recurrent Pattern Detection(TM) technology -- in conjunction with the IMP's workflow processor -- uniquely enables operators and service providers to prioritize email traffic according to its importance. The integrated platform processes in excess of 4.2 million email messages per hour on a single system with this and other industry-leading third party applications. In installations at operators across the world, the IMP already processes well in excess of 200 million email messages per day. "Bizanga was looking for reliable filtering technologies that would also allow for scalable classification of the traffic flow," said Marc Sheldon, Chief Marketing Officer for Bizanga. "Commtouch's RPD(TM) technology provides this capability to our customers, enabling new ways of managing email streams in accordance with their relative importance to the end user. Commtouch's proven email security technology will provide protection for our customers against current and future spam and malware threats." The Commtouch anti-spam and Zero-Hour virus prevention module is available for Bizanga's current and future customers as a fully integrated optional module for the Bizanga IMP as of version 2.5, scheduled for release in July 2006. "We are pleased to be working with Bizanga to expand our reach to service providers globally," said Jay Goldin, Commtouch Inc.'s Vice President of Business Development.
