Crowdsec

CrowdSec provides threat intelligence blocklists that identify and block malicious IP addresses across networks. The company collects data from a crowdsourced network of over 70,000 active users in 190+ countries who share signals about aggressive IPs. CrowdSec curates this data into blocklists for specific industries and threat types—including DDoS, botnets, and exploiters—that integrate with firewalls and CDNs to reduce security alerts and block mass exploitation attempts.
