Note: You must first have CrowdSec installed on your server. The installation is very simple.

CrowdSec is composed of a behavior detection engine, able to block classical attacks like credential bruteforce, port scans, web scans, etc.

Based on the type and number of blocked attacks, and after curation of those signals to avoid false positives and poisoning, a global IP reputation DB is maintained and shared with all network members.

This WordPress plugin is a “bouncer”, which purpose is to block detected attacks with two remediation systems: ban or challenge detected attackers with a Captcha.


You can:

  1. Block aggresive IPs
  2. Display a captcha for less aggresive IPs

Get more info on the CrowdSec official website.
