- Does not control scanning.
- API flag
risk.is_scanner
A user agent alone never sets a flag. Anyone can claim to be Greenbone Cloud Service; the flag follows the address the request comes from.
02 · In the response
What a match looks like.
A lookup of a Greenbone Cloud Service address sets risk.is_scanner. The flags come with geolocation and network data in the same response, for API keys on every paid plan.
The response says which kind of bot an address belongs to, not which operator. A request that claims to be Greenbone Cloud Service while risk.is_scanner is false should not be trusted as Greenbone Cloud Service.

At the edge
- 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.
