OpenCTI by Filigran vs. CrowdSec

OpenCTI is an open-source threat intelligence platform designed to help users manage and operationalize threat intelligence effectively. Built by practitioners for practitioners, OpenCTI aims to break down data silos and ensure that threat intelligence is not only accessible but also actionable. This platform facilitates the seamless flow of threat intelligence across various security systems, making it relevant by integrating business context and enabling the creation of comprehensive threat exposure reports for enhanced executive visibility.

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. If verified, this IP is then redistributed to all CrowdSec users running the same scenario.
