Port Scanner Online, Free Open Port Scanner

Online Port Scanner is an application designed to probe a server or host for open ports. This is often used by administrators to verify security policies of their networks and by attackers to identify services running on a host and exploit vulnerabilities.

A port scan is a process that sends client requests to a range of server port addresses on a host, with the goal of finding an active port. The majority of uses of a port scan are not attacks, but rather simple probes to determine services available on a remote machine. Install Nmap and Use Nmap Commands to scan network.
