The open-source and collaborative IPS
When tens of thousands join forces
Using our free & open-source Agent, you protect your infrastructures and enroll in the largest CTI network on earth. You contribute and curate our real-time blocklist, adding and removing IP addresses as they are used and dropped by criminals.
Local detection, global protection
The IDS automatically identifies 50+ suspicious behaviors in logs and blocks the aggressive IP behind them. This IP is then shared in the network to adjust its real-time reputation. If enough different agents around the world are also tagging the IP, it integrates a global blocklist..
High Performance
Using Go for ultra-fast execution & low-memory usage, CrowdSec’s IDS is well suited to be the CWPP/CNAPP of your containers but can also analyze thousands of log lines per second in any regular Windows, Linux or BSD environment (IPV4 & IPV6 addresses are handled).
Observability
With CrowdSec SaaS console, you can manage fleets of servers & workloads, visualize attacks and alerts in real-time, and remediate intrusion attempts in any way you see fit.
Let our data reinforce your existing tools
CrowdSec is all about data and API. The global network wisdom can be directly injected into any firewall appliance, load balancer, reverse proxy, or at higher levels in business stacks. Let the API tell your tools whether we know about the IP connecting and what we recommend.

GDPR Compliant
Sharing is caring but privacy matters even more. We collect the very strict minimum in order to be GDPR compliant. We never export your logs . The only data sent for curation are a timestamp, the aggressive IP, and the scenario used in the attack.
Ease of use
CrowdSec is developed by former pentesters, SecOps & DevOps, to be a fire-and-forget and easy-to-deploy software.
CrowdSec is available on a variety of OS & containers, and integrated with a large number of services (servers, proxies, WAFs , etc.).
Join the crowd
Our core advantage over the cybercriminals? Our strength in numbers. Together, we stand as a community and act swiftly in coordination. When we join forces, we outnumber the criminals and burn their IPs, one by one, crippling their anonymity.
Leverage CrowdSec across various verticals
VOIP
VOIP operators are frequently the target of credential thefts, allowing criminals to call additionally taxed telephone number services they own to cash-in money. CrowdSec protects VOIP servers by detecting and blocking credential brute forces attacks.
