Symantec made further inroads into the IM world this week when it acquired IMLogic. Exactly how much the deal is worth remains in secrecy, but Symantec believes that the acquisition will help meet increased demand for instant messaging in the corporate world.

"Real-time communication solutions like instant messaging are powerful collaboration tools that create a new attack vector for threats to enter an enterprise network and new forms of digital communication with the same government, legal and business requirements to retain and retrieve as email," said Enrique Salem, senior vice president of security products and solutions for Symantec.
