Good overall; missing one key feature for me
johnb1--2008April 2, 2012
Pros
Clearly displayed information; should help many users see what is connecting to their computer. Good performance; doesn't seem to add overhead to the computer.
Cons
Need to be able to choose network interfaces
Summary
If you want a GUI for seeing what is connecting to your computer, this is a good basic choice.
Helped me.

Pros
Provided the detailed information I needed
Cons
Could be a little easier for the novice user, but I think the problem is in how the system provides information.
Summary
This is a great product when you are trying to find an application that us using a lot of internet/network bandwidth. I used this to find the culprit that was using all by internet allocation and killed the process.
Installed easily and works well.

Summary
Can't say that I know what all the info means, but there it is and presented in real time.

Developer’s Description

By TCPEeye Network Monitoring

For each port in the list, information about the process that opened the port is also displayed, including the process name, full path of the process, version information of the process (product name, file description, and so on), the time that the process was created, and the user that created it. In addition, TCPEye allows you to close unwanted TCP connections, kill the process that opened the ports, and save the TCP/UDP ports information to HTML file , XML file, or to tab-delimited text file. TCPEye also automatically mark with pink color suspicious TCP/UDP ports owned by unidentified applications (applications without version information and icons).
