This allows packet decisions to be made based on more than just source/destination IP Address or ports and can also use information spanning across multiple connections for any given host. Description Īpplication layer filtering operates at a higher level than traditional security appliances. Stickley discovered a second vulnerability a year later, effectively ending Gauntlet firewalls security dominance. Network Associates continued to claim that Gauntlet was the 'worlds most secure firewall' but in May 2000, security researcher Jim Stickley discovered a large vulnerability in the firewall, allowing remote access to the operating system and bypassing the security controls. Gauntlet firewall was rated one of the top application firewalls from 1995 until 1998, the year it was acquired by Network Associates Inc, (NAI). This was the first transparent firewall, known as the inception of the third generation firewall, beyond a traditional application proxy (the second generation firewall), released as the commercial product known as Gauntlet firewall. In 1994, Wei Xu extended the FWTK with the Kernel enhancement of IP stateful filter and socket transparent. However, FWTK was a basic application proxy requiring the user interactions.

The purposes for releasing the freely available, not for commercial use, FWTK were: to demonstrate, via the software, documentation, and methods used, how a company with (at the time) 11 years' experience in formal security methods, and individuals with firewall experience, developed firewall software to create a common base of very good firewall software for others to build on (so people did not have to continue to 'roll their own' from scratch) and to 'raise the bar' of firewall software being used.

Under a broader DARPA contract at TIS, Marcus Ranum, Wei Xu, and Peter Churchyard developed the Firewall Toolkit (FWTK), and made it freely available under license in October 1993. DEC's first major sale was on June 13, 1991, to Dupont.
The product was released by DEC, named the DEC SEAL by Geoff Mulligan - Secure External Access Link. Marcus Ranum's work, based on the firewall created by Paul Vixie, Brian Reed and Jeff Mogul, spearheaded the creation of the first commercial product. Gene Spafford of Purdue University, Bill Cheswick at AT&T Laboratories, and Marcus Ranum described a third generation firewall known as an application layer firewall. The two primary categories of application firewalls are network-based and host-based. The application firewall can control communications up to the application layer of the OSI model, which is the highest operating layer, and where it gets its name. It operates by monitoring and blocking communications based on a configured policy, generally with predefined rule sets to choose from.
