Description

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.

CrowdSec

You can:

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

Get more info on the CrowdSec official website.

Excellent Support

February 15, 2023
Crowdsec is pretty amazing, easy to set up even if you’re not a security expert, and the documentation is straightforward. The plugin is very well supported, and they don’t just blame plugin conflicts, but actually try to understand the problem and help. I would love to see support for multisite, in the form of having network-wide options instead of having to configure the plugin individually per site.

CrowdSec Plugin Crashes WordPress 6.01 Website

July 16, 2022 1 reply
My WordPress server & installation (including PHP version) met or exceeded all requirements. I was running WordPress 6.01 which apparently hasn’t been tested. After downloading and activating the plugin, my site experienced a “Critical Error 503” error and I was unable to access the Admin Dashboard. I was able to overcome this restriction after 2 hours and 15 minutes and deactivating and deleting the CrowdSec plugin allowed me to regain control of my Admin Dashboard and the website was back online.
