Cisco almost acknowledging that the Firepower brand has been devalued and announcing a rebinding effort to Cisco Secure Firewall instead of Firepower.ASA is still actively being developed and seems to still be in competition with FTD In other words they have too many users who prefer ASA over FTD to cut them off.

There is also a third operating system name that confuses people:įXOS was the name of the Sourcefire appliance operating system (Firepower Extensible Operating System) but in the context of Cisco FXOS is only a base OS used to run virtualized or containerized images of either ASA or FTD software (as well as support for third party VMs or containers like Radware Defense Pro). There are basically two operating systems you can choose from for firewall services:Īround 2014-2017 Firepower Threat Defense was offered as an alternative to the ASA image on the 5500-X and branded as ASA with Firepower Services and in 2016 the first Firepower branded firewalls (the 9300 followed by the 4100 and finally the 2100) were introduced. The term Firepower has been used for a lot of different products and comes from the 2013 acquisition of Sourcefire (the makers of Snort IDS).

or if you just don't need the new FTD stuff you can use the straight ASA code and manage it all through the CLI.Īnd then there's going to be some user/manager who is going to want one single esoteric feature of the FTD code and that's going to make you convert everything over to it and your entire management structure because they won't let it go. So pretty much all the newest stuff IS this new FTD code, which includes the ASA functionality in the code base. Older 5500-X can run the new integrated software, but its hardware isn't optimized for it, or it can run the old ASA software, or with a card it can run the ASA w/ the Firepower code. I know this is tedious but I'm going to type back what I perceived, which may not be exactly what you said if I misread it or misunderstood.ĪSA was there, then they added this Firepower/snort feature and put a card into the ASA to do it, then they integrated it into the ASA code and got rid of the card and called it Firepower Threat Defense (FTD). That may sound better because it’s more flexible, but it’s slower and more expensive for the given throughput than the newer hardware. The ASA 5500-X hardware (the older generation) 5500-X can run the ASA software, the FTD software and also the ASA with Firepower services module. from there it would either block or pass it back down to the ASA for egress out the interface.įirepower Threat Defense is an attempt to fuse ASA and firepower services into a single unified engine, rather than the previous way of doing it.įirepower Threat Defense is also the name of the security appliance series that replaces the ASA 5500-X lineup.Īny new Firepower Threat Defense appliance can run either ASA OR FTD software, but cannot run ASA with firepower services. It was like the module was a bolt-on to ASA that had more advanced decision engine with things like Geo blocking and IPS, etc. And then there was firepower threat defense.ĪSA w/Firepower services sends packets that pass the ASA ACL up to the firepower ‘module’ for deeper inspection with snort and other things. Then there was ASA with firepower services module.
