- robots.txt won’t help. It does not control port or vulnerability scanning, so a block has to happen before the request reaches your app.
- Firewall, WAF or CDN. Many offer bot rules you can allow or deny by category.
- In your app. Look up the client address and allow or deny on
risk.is_scanner, alongside the user agent. - Never on the user agent alone. Blocking the name stops only honest clients; allowing it lets anyone in who borrows it.
