GFI LanGuard displays a list of open ports found on the system after a scan.
Apart from detecting open ports, GFI LanGuard uses service fingerprint technology to analyze the services that are running behind the detected open ports. With service fingerprint, GFI LanGuard can detect if malicious software is using the detected open port.
The table below displays a summary of the information gathered by ports node.
