Follow our journey as we upgrade the CrowdSec infrastructure to allow our IPv6-only users to set up CrowdSec without any hiccups.

Delve into IP-based cyber defense and explore how the Network Effect and AI are transforming CTI into crowd-powered Tactical Threat Intelligence.

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?…

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.

COO Laurent Soubrevilla took a gamble when he started CrowdSec with the other founders but made sure to make all the right decisions to ensure it would withstand the challenges of 2022 and 2023. In this article, he shares the story, strategy, and takeaways from launching an open-source and collaborative software company in the field…

There are not many FOSS security tools available for Windows servers, but CrowdSec has made the move to change that. Offering a free tool to keep your Windows servers secure, you gain much more than protection with CrowdSec. Let’s dive into the benefits and take a closer look in this article.
