About CrowdSec

CrowdSec is an open-source cybersecurity company that operates a collaborative, community-driven threat intelligence and IP reputation platform. The core concept is modeled after a "neighborhood watch" approach to internet security, where users share data about malicious IP addresses they detect, collectively building a crowdsourced blocklist that benefits all participants. The platform is designed to detect and block automated attacks, which the company identifies as responsible for over 80% of breaches. When a user's system detects a violation or attack from an IP address, that information is contributed back to the broader CrowdSec community, allowing all members to proactively block those IPs. This shared intelligence model is intended to counteract the asymmetric advantage cybercriminals hold over defenders. CrowdSec targets a broad audience including sysadmins, DevOps, and SecOps teams, with a particular focus on making robust security accessible to individuals and small-to-medium businesses (SMBs) that typically lack enterprise-level security resources. The core product is free and open source, with the company operating a commercial layer on top to sustain its business model ethically. The company also provides a Live Exploit Tracker, a feature that surfaces currently active exploitation activity. Founded by Thibault and Philippe, who previously worked in high-security hosting, CrowdSec is headquartered with a globally distributed team. Its business model relies on monetizing premium features and services built around the open-source engine, while keeping the foundational tool freely available to the community.
