Cloudmark Acquires Bizanga

PRESS RELEASE

San Francisco-February 16, 2010-Cloudmark, Inc., the global leader in carrier-grade messaging security, today announced it has entered into a definitive agreement to acquire Bizanga, Ltd., the global company behind the most scalable and full-featured message processing platform. The acquisition will benefit operators by delivering a unified solution that increases the performance, reliability and security of their messaging infrastructure and decreases their system integration and management costs.

Today's messaging infrastructures are tasked with operating against a deluge of spam, accounting for over 90% of the mail volume that operators receive. To combat messaging threats at their earliest outbreaks, carriers are continually looking for innovative solutions to stop spam as quickly and as early as possible at the network's edge. Through the combination of technologies, Cloudmark plans to move more intelligence from the backend service to the edge of the operator network, enabling higher filtering rates and thereby closing the gap on spammers.

The Bizanga messaging platform uniquely complements Cloudmark solutions, together delivering a holistic messaging security solution that combines messaging management and complete, end-to-end filtering solutions to protect against all forms of current and emerging messaging threats. The acquisition will enable a powerful, single solution that delivers the most robust and highest performing messaging protection against current and emerging threats.

Under the terms of the agreement, intellectual property pertaining to message store technology, previously the BizangaStore product, will be owned by a separate and independently operated entity, led by Jerome Lecat, former chief executive officer of Bizanga. The new entity will focus solely on developing and delivering scalable storage software solutions for the email market.
