What problem it solves

Server operators need to detect malicious behavior across logs and HTTP requests, then apply remediation at the appropriate layers of their infrastructure. They also need a way to benefit from threat intelligence shared by the community.

Key features

• Integrated Security Engine — The Security Engine combines IDS/IPS and WAF capabilities in one solution. It analyzes log sources and HTTP requests to detect malicious behavior.

  Source: README

• Community Blocklist — The community blocklist contains IP addresses identified as malicious by CrowdSec. The Security Engine can proactively block those addresses before they reach protected systems.

  Source: README

• Bot and Scraper Detection — The AppSec component can challenge suspicious requests with a JavaScript proof-of-work challenge. This mechanism targets headless browsers and scrapers while allowing verified crawlers such as Googlebot.

  Source: README

• Distributed Detection and Remediation — The "Detect Here, Remedy There" approach separates analysis from enforcement, allowing logs from several sources to be analyzed in one place. Threats can then be blocked at application, system, or infrastructure levels.

  Source: README

• Extensible Detection Scenarios — CrowdSec includes scenarios for common attacks and supports additional scenarios from the Hub. Existing scenarios can be adapted, and new ones can be created.

Who it may suit

This project may suit operators of Linux, Windows, Docker, or Kubernetes environments who need integrated threat detection, active remediation, and community-sourced IP reputation.

Topics to discuss

• Which deployment patterns best support the "Detect Here, Remedy There" approach?

• How can community blocklists be integrated into existing security workflows?

• Which scenarios or remediation integrations would be most useful to add next?
