CrowdSec

CrowdSec is an open-source security stack that detects aggressive behaviors and prevents them from accessing your systems. Its user-friendly design and ease of integration into your current security infrastructure offer a low technical entry barrier and a high-security gain. Once an unwanted behavior is detected, it is automatically blocked. The aggressive IP, scenario triggered and the timestamp is sent for curation, to avoid poisoning & false positives.
