Do you use / does it makes sense? (SIEM)

[Mitheor]

Quick and, i think, easy question.

Home network. OPNSense (+Sensei) and like 20 hosts (2-3 servers in there).

Do you think a SIEM would be a good idea to get a better view of my network and, if the answer is yes, is possible to integrate OPNSense and Sensei with something like Alienvault?

Thanks!

Any luck with this?  I'd like to configure OPNsense to use AlienVault OSSIM's SIEM as well.
