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. If verified, this IP is then redistributed to all CrowdSec users running the same scenario. By sharing the threat they faced, all users are protecting each other.
