crowdsec
CrowdSec is a community-driven security engine. It detects attack patterns through log analysis and shares threat intelligence across the community for real-time threat defense.
- Log analysis detecting attack patterns from Nginx, Apache, SSH, and WordPress logs
- Community threat database with attacker IP data shared by CrowdSec users worldwide
- Bouncers for automatic blocking via Nginx, iptables, and Cloudflare integration
- Scenarios with flexible YAML-based attack detection pattern definition
- Dashboard for visualizing alerts, decisions, and traffic patterns
- Lightweight agent built in Go with low resource consumption
Built in Go, CrowdSec serves as a modern fail2ban alternative that defends against attack patterns undetectable by individual servers through community-based threat intelligence sharing.
