TCPEye Network Tools is a monitoring tool that always displays the full list of TCP/IP and UDP ports open on your computer.
Each open port is shown on a list, from which you can access detailed information about it including its complete address, name, country flag, the user that created it, and more.
The program also flags suspicious TCP/UDP ports with the color pink if they are not identified. Of course, it only takes a click to completely halt a process.
TCPEye Network Tools is an intriguing application for those users who prefer to keep their network under close watch. If you use this, nothing will slip between the cracks.
