NGINX Abuse Guard Module Auto-Bans Scanners and Bots at Worker Level
The NGINX Abuse Guard module detects and bans abusive clients by tracking error response rates in shared memory, enforcing bans at the preaccess phase before any request processing. It uses a leaky-bucket scoring system that decays over time, allowing it to distinguish burst attacks from occasional errors. The module is installed as a precompiled dynamic module and requires no external tools or scripting.

This module addresses a real gap in NGINX abuse mitigation, but its effectiveness depends on careful threshold tuning to avoid false positives on legitimate traffic.
