Learn more about the port scanner

The port scanner allows you to find computers and servers on the network that have the desired port open. Most often, port availability is checked by system administrators to identify weak points in their networks.

An open port allows you to connect to the device from the internet if there is a program running on this port that is ready to accept the connection.

Our online port scanner is based on the most famous Nmap utility adapted for the web.

To check your computer, click the "insert my IP address" button next to the scanner form. Do not use the scanner to scan third-party servers that do not belong to you.
