Before it was used in real-life computing, the term appeared in the 1983 computer-hacking movie ''[[WarGames]]'', and possibly inspired its later use.<ref>{{Cite web|last=Boren|first=Jacob|date=2019-11-24|title=10 Times '80s Sci-Fi Movies Predicted The Future|url=https://screenrant.com/80s-sci-fi-movies-predicted-the-future/|access-date=2021-03-04|website=ScreenRant|language=en-US}}</ref>
One of the earliest commercially successful firewall and network address translation (NAT) products was the PIX (Private Internet eXchange), invented in 1994 by Network Translation Inc., a startup founded by John Mayes with lead engineer Brantley Coile as the principal software developer<ref>{{Cite web|last=Mayes|first=John|date=2022-11-24|title=NTI - JMA|url=http://www.jma.com/nti.html|access-date=2023-03-04|website=Wikipedia|language=en-US}}</ref>. Recognizing the emerging IPv4 address depletion problem, they designed the PIX to enable organizations to securely connect private networks to the public internet using a limited number of registered IP addresses. The innovative PIX solution quickly gained industry acclaim, earning the prestigious "Hot Product of the Year" award from Data Communications Magazine in January 1995. Cisco Systems, seeking to expand into the rapidly growing network security market, subsequently acquired Network Translation Inc. in November 1995 to obtain the rights to the PIX technology. The PIX became one of Cisco's flagship firewall product lines before eventually being succeeded by the Adaptive Security Appliance (ASA) platform introduced in 2005.
