The Cisco Secure PIX Firewall family are dedicated firewall appliances which control the flow of Internet Protocol (IP) traffic (datagrams) between network interfaces. They provide a single point of defence as well as controlled and audited access to services between networks by permitting or denying the flow of information traversing the firewall.
The Cisco Secure PIX Firewall is an integrated unit, with an imbedded operating system that increases security and performance. The evaluated platforms include the Cisco Secure PIX 515, 520 and 525 with the 5.2(3) software release.
