Cisco Private Internet Exchange (PIX) is a network security system which provides both firewall services and network translation services (dynamic address translation).
It may be used to protect internal private networks from external networks, or to protect an internal sub-network from the enterprise network. It uses a process called Cut-Through Proxies and Adaptive Security.
The Adaptive Security feature applies to the dynamic translation connections and can be applied to static translation connections where every inbound packet is checked against the Adaptive Security algorithm and against connection state information in memory.
An Identity feature lets NIC-registered IP addresses pass through the firewall without address translation while still retaining Adaptive Security.
PIX has a Failover capability where two PIX firewalls are run in parallel, and if one malfunctions, the second transparently maintains the security operations.
