Company Overview

CrowdSec was founded in 2019 and is headquartered in France. It is an open-source collaborative intrusion prevention system (IPS). Unlike traditional signature- or rule-based security solutions, CrowdSec builds a distributed malicious IP reputation database through globally shared community threat intelligence, identifying and blocking attacks from known malicious IPs in real time.

CrowdSec adopts an open-source free model, with core features free for individuals and businesses. Users can deploy the CrowdSec agent to protect servers, websites, and cloud infrastructure. Its unique community collaboration mechanism lets every deployed instance contribute threat data to the global security network, forming a virtuous cycle where "the more people use it, the stronger the protection." CrowdSec supports extensive integration with Nginx, Apache, Cloudflare, Fail2ban, and more, suitable for server security protection at various scales.
