CrowdSec vs Fail2Ban - What to use? (programming.dev)

Hey all, i've decided I should probably setup something else to help block nefarious IP addresses. I've been looking into CrowdSec and Fail2Ban but i'm not really sure the best one to use.

My setup is OpnSense -> Nginx Proxy Manager -> Servers. I think I need to setup CrowdSec/Fail2Ban on the Nginx Proxy Manager to filter the access logs, then ideally it would setup the blocks on OpnSense - but i'm not sure that can be done?

Any experience in a setup like this? I've found a few guides but some of them seem fairly outdated.

Edit: thanks everybody for the great info. General consensus seems to be with crowdsec so I'll go down that path and see how it goes.

Edit 2: So after having it up and running for the better part of a day, i'm going to remove it again. For some reason there was a performance impact loading websites, probably because it was waiting for a response from the Crowdsec hub? Either way, after stopping it from running everything is back to normal again. So I might revisit how I do it and probably try Fail2Ban now instead. Thanks everybody

In addition to the explanation you got from the other user: once you've set up the bouncer middleware in the configs (don't know if there even exists a good way to do that outside of the configs files), you simply assign the middleware in the compose file as usual.
