Crowdsec

App in the BluixApps catalog

What it is

CrowdSec is a collaborative IPS (Intrusion Prevention System) — analyzes logs, detects attacks (SSH brute-force, web attacks, scanners), shares attack data across the CrowdSec community for collective defense. Modern Fail2Ban replacement with community threat intelligence.

For self-hosters running internet-facing services, CrowdSec adds a collective immunity layer beyond static IP blocking.

What it's for

  • Intrusion prevention — automatic blocking of attackers
  • SSH brute-force protection — block scanners attacking SSH
  • Web attack prevention — block SQL injection, XSS attempts
  • Community threat intel — benefit from blocked IPs across CrowdSec network
  • Decoupled detection + remediation — separate analyzers from blockers

Who it's for

  • Self-hosters running internet-facing services
  • SysAdmins managing public servers
  • DevOps teams hardening production infrastructure
  • Security-conscious users wanting community defense
  • Hosting providers protecting customer servers
