Well, only mostly dead. Today, July 28th, 2008 is the last day you can purchase a PIX firewall appliance from Cisco, ending one of the longest and most successful lives of a gateway security product ever. The PIX (Private Internet Exchange) was the first Network Address Translation device and later evolved into a statefull firewall. See this introductory piece on the PIX by Johna Till Johnson in the January, 1995 issue of Data Communications Magazine. Cisco acquired the PIX with Network Translations, Inc. along with its inventors, John Mayes, Brantley Coile and Johnson Wu. From there the PIX grew into a multi-billion dollar franchise out selling its nearest competitors, Checkpoint, and Netscreen.
According to Cisco they will continue to sell add-ons to the PIX series until next year and will support the product until 2013, which has got to be one of the most responsible end-of-life programs in the history of networking and security. While the latest version of PIX is compatible with the first version of Cisco’s replacement security appliance, the ASA, from here on they diverge as ASA moves to a Linux based OS.
