In April 2008, Microsoft announced that the next generation of IAG will be named Forefront Unified Access Gateway. With this version, the SCSI-based Air Gap was dropped, and the product was unified as a single-server appliance which used Microsoft ISA Server. Following this acquisition, the product was renamed Microsoft Intelligent Application Gateway Server 2007. Microsoft completed the acquision on 26 July 2006. On, Microsoft announced that it will be acquiring Whale Communications. The technology developed was called the Air Gap and the communication between the external network and internal network was managed by two separate machines linked together by a memory bank accessed through a SCSI interface. One of the challenges it tried to solve in the nineties was to develop a remote access solution based on a VPN mechanism but without direct network access from the remote client to the corporate network. Unified Access Gateway was originally developed by a startup company named Whale Communications in Rosh HaAyin, Israel.
