CrowdSec is a collaborative, free, and open-source Endpoint Detection & Response (EDR) software suite. CrowdSec analyzes visitor behavior & provides an adapted response to all kinds of attacks. It detects unwanted behaviors in applications & system logs to then enforce remediation at any level (firewall, reverse proxy,) and of any sort (MFA, Captcha, drop).
Another major strength of the product comes from its user network. CrowdSec also enables users to protect each other. Each time an IP is blocked, all community members are informed so they can also block it. This collective, highly distributed crowd-sourced threat intelligence offers an extra layer of protection. Therefore, CrowdSec combines both behavior and reputation, allowing everyone to have each other’s back and form a global cyber defense shield.
Already used in 100+ countries, the solution builds a real-time IP reputation database that will benefit individuals, companies, and institutions.
