Nir Zuk says he developed the technology used in all firewalls today. David Pensak claims to have built the first commercially successful firewall. Marcus Ranum says his own reputation as inventor of the firewall is "marketing BS," and that David Presotto is the man. (See Ranum’s Wild Security Ride.)

William Cheswick and Steven Bellovin, who literally wrote the book on firewalls in 1994 while at AT&T Bell Labs, say they didn’t invent the firewall, either -- they built a circuit-level gateway and packet filtering technology.

But all of these security experts -- as well as Jeff Mogul, Paul Vixie, Brian Reid, Fred Avolio, and Brent Chapman, and others -- were associated in some way with the roots of firewall technology. Several of them have been called the father of the firewall, but most experts agree that there’s not just one biological father of the technology. "There were lots of people involved in it... The idea was floating around," Ranum says.
