PingKit's port scanner attempts TCP connections to a range of ports on any host you specify. For each port, it reports whether the port is open, closed, or filtered, and identifies the service typically associated with that port number. It is the same fundamental technique used by professional tools like nmap, packaged in an interface you can use from anywhere on your phone.
Scan common ports or the full range from 1 to 65535. Results show open, closed, and filtered states so you know exactly what is exposed and what is properly locked down.
Open ports are labeled with their commonly associated service — HTTP, HTTPS, SSH, FTP, MySQL, RDP, and hundreds more. Quickly understand what is running without memorizing port numbers.
Scan a single port, a specific range, or use built-in presets for common services, web servers, databases, or the top 100 most used ports. Flexible enough for any use case.
Verify your firewall is blocking what it should. Check that decommissioned services are no longer listening. Confirm that only intended ports are reachable from outside your network.
You deployed a web server and need to confirm ports 80 and 443 are open while everything else is closed. Or you just changed your SSH port from 22 to a custom number and want to verify it is reachable. PingKit lets you run these checks from your phone, from any network, without needing to SSH into another machine first.
Penetration testers and security-conscious administrators use port scanning as the first step in assessing an attack surface. PingKit shows what an external attacker would see when probing your host. If your database port is open to the internet or an old service is still listening on a port you thought was closed, you want to find that before someone else does.
An application cannot connect to a server? Before diving into application logs, check whether the port is even reachable. If PingKit shows the port as filtered, the problem is a firewall or network configuration — not the application. If the port is closed, the service is not running. If it is open but the app still fails, the issue is at the application layer. Port scanning eliminates the most common causes in seconds.
Firewall rules are easy to get wrong and hard to verify from the inside. The only reliable way to confirm a firewall is working is to test it from outside. Run PingKit's port scanner from your phone on cellular data to see exactly what your server or home network exposes to the internet. Compare the results against your intended rules and close any gaps.
Port scanning is one piece of the network security puzzle. Pair it with PingKit's Security Scan for an automated vulnerability assessment, use the Device Scanner to discover every host on your local network, or run a DNS Lookup to verify records before scanning. With 19 tools in one app, you can go from discovery to diagnosis to verification without switching apps or reaching for a laptop.
