GTA was founded by a group of software engineers in 1992, and in 1994 was one of the first companies to introduced a commercial firewall. The original firewall they introduced was the GFX-94. The GFX-94 was a stateful firewall with unique dual walled design that consisted of two separate hardware devices comprising the inner and outer firewall. The GFX-94 was in the first group of firewalls certified by the NCSA (now ICSA). In 1996 GTA introduced the first tiny footprint firewall, the GNAT Box firewall, which fit entirely on a 3.5" floppy diskette. The GNAT Box firewall evolved into the current GB-OS. GB-OS is the operating system for all GTA firewalls and carries the ICSA Firewall Certification.
