HIS is the successor to Microsoft SNA Server. SNA Server was released in 1994, and was one of the first add-on products available for the fledgling Windows NT. SNA Server was also included in Microsoft BackOffice Server.

Similar gateway products were NetWare for SAA (defunct, ran on Novell NetWare) and IBM Communications Manager/2 (defunct, ran on OS/2).

HIS has an active ecosystem of third party hardware (e.g. network adapters supporting ESCON and Twinax connectivity) and software.[2]
