Fail2ban on a Mac
Bans IPs after suspicious activity (intrusion prevention) · Security Tools
Fail2ban scans log files and bans IPs that show malicious signs (too many failed logins). Configure jails in jail.local. This pane manages fail2ban on your linked servers over SSH: install it, start, stop and reload it, see each jail's failures and bans, and unban addresses. Shared Fleet Settings (ban time, retries, escalating bans, never-ban addresses and which jails to turn on) are pushed to the servers you pick as jail.d/frontierstack.local, with a config test and automatic rollback; or copied from a server you've already tuned. This Mac's own fail2ban is managed in the Security pane (Intrusion Prevention). Free, open-source software: there is no paid plan.

Run it from your Mac.
