The Adaptive Security Appliance is a network firewall made by Cisco. It was introduced in 2005 to replace the Cisco PIX line. Along with stateful firewall functionality another focus of the ASA is Virtual Private Network (VPN) functionality. It also features Intrusion Prevention and Voice over IP. The ASA 5500 series was followed up by the 5500-X series. The 5500-X series focuses more on virtualization than it does on hardware acceleration security modules.

History
In 2005 Cisco released the 5510, 5520, and 5540.

Software
The ASA continues using the PIX codebase but moves from the Finesse/Pix OS operating system platform to the Linux operating system platform. It also integrates features of the Cisco IPS 4200 Intrusion prevention system, and the Cisco VPN 3000 VPN concentrator.

Hardware
The ASA continues the PIX lineage of commodity Intel 80x86 hardware.
