Features & Advantages

Versatile Security Engine

CrowdSec Security Engine is an all-in-one IDS/IPS and WAF.

It detects bad behaviors by analyzing log sources and HTTP requests, and allows active remediation thanks to the Remediation Components.

Detection rules are available on our hub under MIT license.

CrowdSec Community Blocklist

The "Community Blocklist" is a curated list of IP addresses identified as malicious by CrowdSec. The Security Engine proactively blocks the IP addresses of this blocklist, preventing malevolent IPs from reaching your systems.

Multiple Platforms support

Multiple Platforms support

Outnumbering hackers all together

By sharing the threat they faced, all users are protecting each other (hence the name Crowd-Security). Crowdsec is designed for modern infrastructures, with its "Detect Here, Remedy There" approach, letting you analyze logs coming from several sources in one place and block threats at various levels (applicative, system, infrastructural) of your stack.

CrowdSec ships by default with scenarios (brute force, port scan, web scan, etc.) adapted for most contexts, but you can easily extend it by picking more of them from the HUB. It is also easy to adapt an existing one or create one yourself.

Installation

Follow our documentation to install CrowdSec in a few minutes on Linux, Windows, Docker, OpnSense, Kubernetes, and more.
