Hello everyone. Yes, it is 2020 and I am still speaking about ASA…
On one side I recently bought myself an ASA-5506-X with FirePOWER services, to extend my lab, to see how it works, and to do some experiments I can not do on a customer environment :). On the other side I also recently bought a Firepower 1010 to see the evolution Cisco made from ASA to ASA with FirePOWER and finally Firepower. We also have to assume that there are still a lot of ASA Firewalls out there and they will remain for a while before replacement.
At first sight, we may not find any difference between the wording Firepower and FirePOWER. But there is one… a significant one.
When Cisco mentions the word FirePOWER, then they talk about ASA-Devices with a Firepower Image on top running as a module.
In contrast to this, when Cisco speaks about Firepower then they are mentioning the Firepower Threat Defense device.
