Created to fill the need for the ability to cutoff an established network connection (TCP**) between your computer and another computer without dropping your network connection entirely. eSTOP! was developed as a security product with the intent to (e)mergency STOP problem TCP** connections. It displays in real-time any TCP** connection in or out of your computer. You can instantly stop connections by double clicking on the connection in the list or by pressing one of the three large red buttons on the main window. eSTOP! is not a firewall. eSTOP! complements a firewall because you can use it to stop connections normally permitted by the firewall. You can make eSTOP! popup whenever connections happen--then do something about those connections. This version is free for personal and non-profit use. Other use like business, government and educational institutions will have to license eSTOP! on a per workstation basis for a modest fee after a trial period.
