crowdsec

CrowdSec is an open-source security solution that leverages community‑driven threat intelligence to protect servers, containers, and applications from malicious traffic. It parses logs, detects attacks, and automatically bans offending IPs using a shared blacklist that evolves with real‑world data. The platform provides ready‑made parsers and scenarios, a powerful API, and integrations with firewalls, proxies, and orchestration tools, enabling both small teams and large enterprises to benefit from collective cyber‑threat intelligence without vendor lock‑in.
