Firepower to suricata

Brand new to suricata and had a few questions I am unable to find answers for. Currently using ASA5545-X with firepower services managed via FMC.

With firepower, we have to run an AD user agent and TS user agent to detect users via logs so the access control policies will apply as they are built by user/ AD groups etc.

Does suricata offer this functionality?
Is there any type of support?
Anyone else moved to suricata from firepower?

Would love to hear from those who have if so.

I don’t know how those Cisco stuff works but with Suricata you monitor the traffic not logs. So as long as you see the actions within the network traffic you could apply signatures on that.
