ePresence(ePresence, Westboro, MA) A well-established consulting company specializing in systems integration and secure identity management that was acquired in 2004 by Unisys. Its history dates back to 1983 when it was founded as Banyan Systems, Inc., named after the Banyan tree.
Banyan was known for its sophisticated VINES network operating system and Streettalk directory products, which were way ahead of their time and which became dominant in federal government before Novell and Microsoft made major inroads. Banyan discontinued its products in 1999, but used its vast experience to reposition itself as a consulting services organization. In 2000, Banyan acquired ePresence, Inc., a privately held company specializing in Web design and development, and changed its name to reflect its e-business offerings.
