- Easy installation as a standalone firewall or integration with existing firewalls like iptables, nftables, Caddy, Nginx, Traefik, and more.
- Auto-scaling architecture to handle increased traffic during DDoS attacks.
- Lightweight software with low resource usage for efficiency.
Overall, CrowdSec leverages shared intelligence from the cybersecurity community to protect servers and infrastructure in real-time against various attacks like brute-force, web scraping, SQL injections, and more which makes it a handy open-source security tool.
