Download ProcessTCPSummary
ProcessTCPSummary is active immediately after opening and gathers/displays details for every process including the total number of TCP connections, the number of TCP connections for each status (Established, Listening, Syn-Sent, Syn-Received...), total IPv4 TCP and IPv6 TCP connections, common port numbers, and more. You also have the advanced option to run ProcessTCPSummary as an Administrator which will grant you the ability also to watch the number of TCP/UDP bytes sent/received by every process as well as the current send/receive speeds.
ProcessTCPSummary is a great option for verifying that there are no unwanted ports open as these can be leveraged by cyber-criminals intending to insert malware, ransomware, etc., so having an accurate picture can be useful to help you keep an eye out for issues.
ProcessTCPSummary 1.16 has been released. ProcessTCPSummary is a simple portable option that gathers and displays all processes that have TCP connections or listening UDP ports.
