CloseTheDoor is a software program that provides users with a simple means of detecting network security holes and closing them with a minimal amount of effort, so as to prevent remote attacks.

Simple installation and clear-cut GUI

You are required to go through a seamless setup process which is over in a jiffy. After you complete it, you are brought to an interface which can only be described as simple and clean, seeing it only encompasses a menu bar and a pane in which to display detected information.Moreover, it comes bundled with a pretty long list of Internet referrals and therefore, it becomes quite clear that all types of users can find their way around it with ease.

Data you can view and save to the HDD

This application enables you to view all detected listening ports as a list in the main window, along with details such as interface, port number, protocol type, process, product ID, associated services, company and a short description. It can be refreshed with just a click of the button, while you can also export the results to a CSV format or display a summary in another window.

Manage listening ports and access some tools

You can terminate a selected process, as well as locate its executable file, disable services or uninstall them. Aside from that, you should know that you can also look online (e.g. Google, Wikipedia) for information pertaining to a port or process.Last but not least, it is possible to access Windows tools such as the Registry Editor, Task Manager, Services, Network connections and System configuration.

The interface is suitable to all types of users, the response time is good and the amount of resources required is insignificant at all times. We did not come by any errors, crashes or freezes in our tests.
