CrowdSec on a Mac
Behavioural detection + IP blocking (crowd-sourced) · Security Tools
CrowdSec parses logs to detect malicious behaviour (brute-force, scanning, web attacks) and blocks the source IPs via 'bouncers' (firewall/nginx/Cloudflare), sharing signals across a community blocklist — a modern successor to Fail2ban. Install the agent with Homebrew (crowdsec) plus a bouncer; scenarios/collections come from the CrowdSec Hub, and the local API is managed with cscli. Managed alongside Fail2ban in the Security pane's Intrusion Prevention.
