+      CrowdSec is a free, modern & collaborative behavior detection engine,
+      coupled with a global IP reputation network. It stacks on fail2ban's
+      philosophy but is IPV6 compatible and 60x faster (Go vs Python), uses Grok
+      patterns to parse logs and YAML scenario to identify behaviors. CrowdSec
+      is engineered for modern Cloud/Containers/VM based infrastructures (by
+      decoupling detection and remediation). Once detected you can remedy
+      threats with various bouncers (firewall block, nginx http 403, Captchas,
+      etc.) while the aggressive IP can be sent to CrowdSec for curation before
+      being shared among all users to further improve everyone's security.
