Less than 12 months after the company filed for a $57 million IPO (which was subsequently pulled), Long Island's Sybari Software announced plans to be acquired by Microsoft for an undisclosed sum. According to Newsday, Sybari is "expected to become a major lynchpin of Microsoft's widely anticipated movement into the consumer and corporate security market." On news of the deal, shares of rival security software makers, including Symantec and McAfee, sank -- the clearest indication that Microsoft's acquisition of Sybari will change the competitive picture for the enterprise security software market.
