- Risky services such as Telnet, SMB and RDP are reflected in the trust score

Frequently asked questions
Why can I not scan another IP address?
Unauthorized port scanning is open to abuse. That is why only the requesting IP address is scanned. To check whether a single port is reachable on another address, use the Global reachability test.
Does it see devices behind my home router?
No. The scan targets the address visible from the internet; devices on your local network are not visible.
