Not able to setup a Domain Age rule rule in Cisco Firepower 6.6.5?

[Mogwai]

I've poked around a bit and haven't been able to see a way in order to implement a domain age rule on our Cisco Firepower which is running 6.6.5. I see online that a rule can be created using Cisco umbrella, but is there really not a way to implement this on the firewall itself at this time?

There are settings in your Access Control Policy's Security Intelligence (SI) that allow you to add "Newly_Seen" (networks) and "URL_Newly_Seen" (URLs) to the Block list.

See the following example:

FMC SI Newly Seen blocking

Found out that this wouldn't be possible for our environment. Closing this thread.
