PortScan
Is your server open to the outside?
Find out whether your server is open to the outside, with a real connection.
Highlights
Real connections, not guesses.
An external server makes actual TCP connections to decide open, closed or filtered, and shows the banner of every open port.
Right from your phone.
The Android app scans directly from your phone’s network and adds a reference security score and per-port guidance.
Built to prevent abuse.
Human verification is bound to the target address, so one check can’t be used to sweep many targets.
