For us, the FOSS business model is about creating enterprise-grade open-source software while aligning community, investor, and client interests.

While working on some new features for CrowdSec, we also have been experimenting with scenarios focused on post-exploitation behaviors, relying on auditd for Linux. That experiment led to another…how quickly can a machine get compromised? How fast can the CrowdSec network spot this compromised machine? And, how fast will it make its way to the crowdsourced blocklist? This article will answer all these questions and more!

We report on the Netgear RCE, provide data on the exploit, show how the exploit works in practice, and speculate on vulnerability still persist in the wild.

All users on the CrowdSec Console can now subscribe their instances to third-party blocklists cherry-picked by our expert team. With these 14 blocklists, including 3 premium ones, you can secure your systems against VoIP fraud, botnets, and more.

Scenarios are core elements of the CrowdSec detection engine and enable it to recognize suspicious behavior as well as make a decision on whether to block an IP. Discover how to modify existing scenarios, and help make the community safer by creating new ones.

Actually, Bennet first reached out to us with suggestions for improvement but then ended up liking CrowdSec so much that he enrolled as an ambassador. We’re very happy about that and for everything, […]

We were so lucky to get an interview with early CrowdSec supporter and contributor of the CrowdSec Traefik bouncer Fabien Bonalair. The Traefik bouncer empowers existing Traefik Proxy users to mitigate security threats from attackers directly in Traefik. Obviously, this is terrific – especially in a K8s environment where blocking traffic using a host firewall […]
