Cybercriminals need IP addresses to mask their locations. By teaming together, we burn a resource precious to their operations. CrowdSec is a platform federating blue teamsto secureall Internet-exposed infrastructures.
CrowdSec offers a crowd-based cyber security suite to protect your online services, visualize & act upon threats, and a TIP (Threat Intel Platform) to block malicious IPs.
The collaborative malicious activity detection and remediation tool. And it’s open-source & free!
The cockpit to monitor your server's security, visualize intrusion attempts, get alerts on unusual activities, and collect intelligence on IP addresses.
The largest Cyber Threat Intelligence (CTI) network on earth, fueled in real time by the CrowdSec community.

Where you can use CrowdSec
CrowdSec runs on Linux, Windows, VMs, containers or bare-metal servers. It can even be interfaced with your existing code through our API.
Languages & Frameworks
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..
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).
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.
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
Ecommerce websites are amongst the most attacked websites. Most commun attemps include page scraping, credit card stuffing, credential stealing or scalping. CrowdSec provides protection against intrusion attempts by detecting all malicious activity and banning nefarious traffic while limiting false positives.
CrowdSec offers Managed Security Service Companies a simple all-in-one tool to monitor intrusion attempts on fleets of servers. Able to detect a large variety of attacks, CrowdSec comes with a dedicated SaaS tool to visualise and remediate all nefarious activity.
With 50% of internet traffic generated by bots, Security Operations Center analysts are frequently overwhelmed with alerts and false positives. CrowdSec identifies automated and malicious trafic to feed only highly curated data to analysts, to remove alert fatigue and allowing users to focus on high priority threats.

Yannick Siegler has been one of our earliest adopters and most involved community members. Discover his CrowdSec use cases, both personal and professional.
Esyoil is using CrowdSec to bring multiple data sources together and block IPs before they even act, leveraging log analysis.
Open-source before it was cool
At CrowdSec we believe the best way to develop cybersecurity software is through open-source. We are all about transparency, trust and code quality.
The Agent has always been and will always remain open source (MIT license). We will open source other components of the CrowdSec solution in the future.
