## What is PortScan?

PortScan is a port scanner that checks open ports on servers, routers and NAS boxes right from your iPhone. It opens TCP connections to the target directly from your phone's network and reports each port as open, closed or filtered.

HOW IT WORKS
• Enter a domain or IP and tap the big circle to start
• Choose common ports (21), top 100, top 1000, all 65,535, or your own list (e.g. 22, 80, 8000-8100)
• Open ports appear on the circle as they are found, and for SSH, web servers and more the app reads the software version from the response

SECURITY SCORE
A reference score based on what is open (services risky to expose to the internet, unencrypted protocols) and known vulnerable versions, with a list of what to look at.

USEFUL FOR
• Checking your home router, NAS or cameras for ports that shouldn't be open
• Verifying port forwarding and firewall rules
• Saving or sharing results as CSV

PRIVACY
No login and no personal data collected. Scan targets and results are never sent to a server.

Only scan hosts you own or have permission to test.
