Check open ports on workstations and show TCP and UDP port numbers open for incoming connections


This free open port scanner tool performs a check for open ports on all Windows workstations locally. An open port (also called a listening port) indicates a slot accessible via TCP of UDP protocol configured to accept incoming packets. For example, if a web server was running on a computer, the default HTTP and HTTPS ports (80 and 443 respectively) would be open.

Action1 can routinely test if certain ports are open and act as a simple open port check tool that is managed from the Cloud, but the actual port scanner tool runs inside your network. Think of it as a command to check open ports in Windows that can be launched simultaneously on multiple computers without using any PowerShell scripts or other standalone tools.
