About Fail2ban
Fail2ban is a daemon that scans log files and bans IP addresses that show malicious signs like repeated failed login attempts. Self-hosting it on a small server, NAS, or VPS keeps the service available on your terms and makes backups and migrations straightforward. Regular community releases, public issue trackers, and extensive documentation help new administrators get from a first install to daily use quickly.
