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.
Sign-up for Action1 Free Edition to receive real-time alerts and view instant data from your endpoints, such as alert on Check Open Ports created, deleted or modified or run live or scheduled queries with the ability to export to CSV or Excel. Action1 Endpoint Security Platform is entirely SaaS, with online web interface (no management tools to install) and it has zero cost for basic functionality. Running in the Cloud, Action1 discovers all of your endpoints in seconds and you can query your entire network in plain English.
