Modules below are no longer sold by Cisco, however, they will be fully supported until 30 th of September 2018. Note: The Cisco ASA 5500 series hardware modules for ASA-5505, ASA 5510, ASA 5520 & ASA 5540 have been announced as End-of-Sale & End-of-Life. While this article covers the hardware modules available for the Cisco ASA 5500 Firewall series, upcoming articles will cover both software and hardware modules along with Cisco FirePOWER & FireSIGHT management services for the newer ASA 5500-X series. With the addition of the software or hardware module, customers are able to increase the firewall’s security and protection capabilities while at the same time simplifing security management and administration by dealing with a single firewall device instead of multiple firewall, IPS or IDS devices. In recent years, we’ve seen Cisco tightly integrate separate security technologies such as Intrusion Prevention Systems ( IPS) and Intrusion Detection Systems ( IDS) within the ASA Firewall appliances in the form of hardware module add-ons (older 5500 series & newer 5500-X series) and, recently, software modules supported only by the newer ASA 5500-X series security appliances.

Since the introduction of the PIX and ASA Firewall into the market, Cisco has been continuously expanding its firewall security features and intrusion detection/prevention capabilities to adapt to the evolving security threats while integrating with other mission-critical technologies to protect corporate networks and data centers.

Cisco’s Adaptive Security Appliance ( ASA) Firewalls are one of the most popular and proven security solutions in the industry.
