    CrowdSec is a new security project designed to protect servers, services, containers, or virtual machines exposed on the internet with a server-side agent. It was inspired by Fail2Ban and aims to be a modernized, collaborative version of that intrusion-prevention framework.

    CrowdSec is -and will always remain- free and open source (under an MIT License), with the source code available on GitHub. It is currently available for Linux, with ports to macOS and Windows on the roadmap. The solution is written in Golang and was designed to run on modern, complex architectures such as clouds, lambdas, and containers. To achieve this, it's "decoupled," meaning you can "detect here" (e.g., in your database logs) and "remedy there" (e.g., in your firewall or rproxy).

    Aggressive IPs are dealt with using bouncers. The CrowdSec Hub offers ready-to-use data connectors, bouncers (e.g., Nginx, PHP, Cloudflare, Netfilter), and scenarios to deter various attack classes. Bouncers can remedy threats in various ways.

    The goal is to leverage the power of the crowd to create a very accurate IP reputation database. When CrowdSec bounces a specific IP, the triggered scenario and the timestamp are sent to our API to be checked and integrated into the global consensus of bad IPs. Our vision is that once the CrowdSec community is large enough, we will all generate, in real time, the most accurate IP reputation database available. This global reputation engine, coupled with local behavior assessment and remediation, should allow many businesses to achieve tighter security at a very low cost. Currently, our community members come from 50+ countries across 6 different continents.*4OyxZQpWbD17C6jO
