Cybercriminals use compromised machines’ IP addresses to stay anonymous. But by teaming together, Sysadmins, Devops & Secops can outnumber them and burn all their precious masks. That is the essence of CrowdSec: a collaborative Cyber Security effort to secure the Internet, our countries, companies, institutions, privacies, personal data.

CrowdSec offers a crowd-based cybersecurity suite, designed to protect your online services, a dashboard to visualize & act upon threats and a TIP (Threat Intel Platform) to block IP known to carry aggressions
HOW TO GET started?
The cockpit to monitor your server's security, visualize intrusion attempts, get alerts on unusual activities, and collect intelligence on IP addresses.
The collaborative malicious activity detection and remediation tool. And it’s open-source!
The biggest Cyber Threat Intelligence (CTI) network on earth, fueled by the CrowdSec community.
Rogue IPs under scrutiny

The open-source and participative cyber defence solution
CrowdSec runs on Unix & Windows, VMs, containers or bare-metal servers. It can even be interfaced with your existing code through our API.
Our strength comes from our cybersecurity community that is burning cybercriminals’ anonymity. By sharing IP addresses that aggressed you, you help us curate and redistribute a qualified IP blocklist to protect everyone preventively. Through collaboration, we provide security to the largest number.
CrowdSec acts on two levels.
Locally, on your servers where the Agent analyzes activity logs in real time, identifies suspicious behavior, acts upon IPs and shares the data with the community.
Globally, by aggregating, curating and redistributing blocklists to the community, to preventively block all flagged IPs on every CrowdSec user's machine.
Developed in Go for ultra fast execution and low-memory footprint, CrowdSec can analyze thousands of lines of logs without impact on user service.
No matter if your servers or attackers are using IPV4 or IPV6 addresses, CrowdSec will do the job.
Dashboards are great steering tools. CrowdSec is instrumented with Metabase & Prometheus to help you with visualization.
With the CrowdSec console, you can manage fleets of servers, visualize attacks and alerts in real-time and remediate intrusion attempts.
Cybersecurity is about cumulating layers of defense. If you already use security tools to protect your assets, CrowdSec integrates nicely with stacks already in place through APIs to feed them with intelligence and boost their efficiency.
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.
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.).
Our core advantage over cyber criminals? Numbers. We have to stand as a crowd and act in a coordinated way. When you, Sysadmins, DevOps & SecOps join forces, you outnumber them and can burn their IPs one by one, crippling this precious anonymity.
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.
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.
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.
