With the expansion of Cisco ASA models and the addition of new types of devices, it is inevitable to have also a confusion about which software version is supported for each model.
A few years ago we had only the Cisco PIX series which were replaced by the successful Cisco ASA 5500 series firewalls.
Now we have also the next generation 5500-X series and also we have ASA running on 6500 as service module and also the ASA 1000V cloud firewall. Each type has its own software version as shown below:
|

| Cisco ASA 5500 Series (5505, 5510, 5520, 5540, 5550, 5580) | ASA Version 8.4(x) |
| Cisco Catalyst 6500 Series ASA Services Module | ASA Version 8.5(x) |
