As a wholly owned subsidiary of Microsoft, Sybari will continue to offer enterprise protection products for the Microsoft Windows platform.

Microsoft Corp., today announced the completion of its acquisition of Sybari Software Inc., a provider of security products.

Microsoft had signed definitive agreements to acquire Sybari Software Inc., on February 8 2005. As per the agreement, the existing Sybari sales channel and licensing models will remain intact for future, and Microsoft's Sybari operations will continue to have their headquarters in East Northport, New York. As a wholly owned subsidiary of Microsoft, Sybari will continue to offer enterprise protection products for the Microsoft Windows platform.

Microsoft will offer and support Sybari products for the Microsoft Windows platform, including Antigen for Microsoft Exchange, Microsoft SharePoint Portal Server and Windows SharePoint Services, Instant Messaging, SMTP Gateways and for Domino on Windows NT. It will offer customer support for all the Sybari products offered before the acquisition and will discontinue new sales of Antigen products for the UNIX and Linux platforms.

"Customers have told us they want powerful security solutions for the enterprise to help protect their messaging and collaboration servers from viruses, worms and spam," said Mike Nash, corporate vice president of the Security Business & Technology Unit at Microsoft. "Sybari's award-winning and innovative products coupled with its strong industry partnerships and deep integration with such products as Microsoft Exchange Server 2003 will deliver immediate value to Microsoft customers."
