Our free network tool checks the open or closed status of a single port on your local machine.
The port check process is a crucial for network security, allowing administrators to identify open ports and vulnerabilities on target devices. This enables you to identify potential vulnerabilities and determine if any ports are left open or unsecured, which could lead to unauthorized access or data breaches.
Enter your localhost address e.g localhost or 127.0.0.1 and the port number to scan then click the scan button to get the result.
