Banyan Systems, Inc., was founded in 1983 by Anand Jagannathan, a software engineer and mid-level manager at Data General, Larry Floryan and David C.

Banyan was a privately held entity for nearly ten years after its incorporation.

Subsequently it went into decline, facing competition from Novell NetWare and even more so from Microsoft Windows NT.

In October 1999 Banyan Worldwide became ePresence, an internet services company providing collaboration, security and identity management solutions.

On October 24, 2003 ePresence announced that it would cease operations and its assets would be acquired by Unisys.
