IMlogic, a private company in Waltham, Mass., sells software used to manage and secure enterprise instant messaging (IM) systems. The company is estimated to have made US$72 million in revenue in 2004.

IMlogic's IM Manager software provides policy enforcement for regulatory compliance and centralized security controls, and it manages, secures, logs and archives all IM traffic, including messages on AOL Instant Messenger, MSN, Yahoo!, ICQ, IBM Lotus Instant Messaging, Microsoft Office Live Communications Server and Jabber systems.

Cupertino, Calif.-based Symantec and IMlogic have been partners since 2002, allowing Symantec's Enterprise Vault e-mail and content-archiving software to be integrated with IMlogic's IM Manager so that both e-mail and IM traffic could be archived and searched. Symantec said the acquisition will lead to a tighter integration between those two products.

Enrique Salem, senior vice president of security products and solutions at Symantec, said in a statement that with the IMlogic acquisition, "Symantec will be the first and only vendor to offer a complete security and archiving solution to help customers manage all their messaging requirements."
