CrowdSec scans also firewall logs like PSAD and much more applicative logs types than fail2ban. That being said I use tailscale to ssh to my servers.

Sorry for answering late, hope you will see my comment.

Is it necessary to add a vpn connexion to a server on top of the ssh one? Here is someone else asking the same question: https://news.ycombinator.com/item?id=35957349

I would be interested to have your feedback.
