KeyShield: AI‑Powered IP Defense for SSH & VPN

SSH key‑only users find fail2ban ineffective against port scans and brute‑force attempts, while many still expose port 22. KeyShield automatically aggregates authentication logs across SSH and VPN services, applies AI‑driven heuristics, and blocks malicious IPs in real time, ensuring secure access without manual firewall tweaking.

Comment on: I close SSH port 22 (and what I use instead)

> if you're using key-only authentication (which: of course you are) fail2ban has literally no function (unless you think attackers are brute-forcing ECDH keys).Why, fail2ban here still serve a very useful function: it bans the offending IP from talking to the machine. It's a simple and a very effective heuristic to block both non-offending port-scans and offending too.> basically two waysIt's always amusing what people like you almost demand what ssh should be run on the port 22 but are fine with a random port for WireGuard.And for all of you to assume what both 22/tcp and WireGuard are alway
