## <TL;DR>
|
||||
|
||||
CrowdSec is a free, modern & collaborative behavior detection engine, coupled with a global IP reputation network. It stacks on fail2ban's philosophy but is IPV6 compatible and 60x faster (Go vs Python), uses Grok patterns to parse logs and YAML scenario to identify behaviors. CrowdSec is engineered for modern Cloud / Containers / VM based infrastructures (by decoupling detection and remediation). Once detected you can remedy threats with various bouncers (firewall block, nginx http 403, Captchas, etc.) while the aggressive IP can be sent to CrowdSec for curation before being shared among all users to further improve everyone's security. See [FAQ](https://doc.crowdsec.net/docs/faq) or read below for more.

## Outnumbering hackers all together

By sharing the threat they faced, all users are protecting each-others (hence the name Crowd-Security). Crowdsec is designed for modern infrastructures, with its "*Detect Here, Remedy There*" approach, letting you analyse 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 context, but you can easily extend it by picking more of them from the **[HUB](https://hub.crowdsec.net)**. It is also easy to adapt an existing one or create one yourself.

|
||||
## :point_right: What it is not
|
||||
|
||||
CrowdSec is not a SIEM, storing your logs (neither locally nor remotely). Your data are analyzed locally and forgotten.
|
||||
|
||||
Signals sent to the curation platform are limited to the very strict minimum: IP, Scenario, Timestamp. They are only used to allow the system to spot new rogue IPs, rule out false positives or poisoning attempts.
