WP fail2ban
60,000+ active installs · Rated 4.2/5 · Updated October 20, 2026
A plugin that writes WordPress login and other security events to the system log in a format the fail2ban tool understands, so repeated attacks can be blocked at the server level. It suits administrators with server access who already use fail2ban. The plugin is free, with a paid edition adding extra features.
