Curated Threat Intelligence Powered by the Crowd | CrowdSec

CrowdSec is an open-source collaborative security platform providing IP reputation threat detection and remediation through a distributed network of sensors that share threat intelligence. The platform analyzes attack patterns across its participant network identifying malicious IPs and automatically generating remediation blocks. CrowdSec provides bouncers for nginx Apache firewall and many platforms for blocking detected threats. Organizations join the CrowdSec network to benefit from collective threat intelligence and contribute their own attack observations.
