CrowdSec

CrowdSec is an open-source, community-driven security automation and intrusion prevention system designed to protect servers, applications, and networks from malicious activities. It analyzes logs in real time, detects suspicious behavior, and applies remediation using bouncers to block attackers. CrowdSec also shares anonymized threat intelligence with its global community to improve collective defense.

Features of CrowdSec:

• Behavior-based detection engine for real-time threat analysis.
• Supports a wide variety of log sources (SSH, Nginx, Apache, firewalls, CMS, etc.).
• Collaborative threat intelligence shared across the CrowdSec community.
• Lightweight and efficient, suitable for modern infrastructure and cloud environments.
