Egis for Mac
Egis is a simple and straightforward OS X utility that makes it very simple to closely monitor your applications connections to remote server on the Internet.
Be warned though, although it worked like a charm on a Mac running OS X 10.7, Egis failed to display the active connections on OS X 10.9. Therefore, unless you use an older OS X version, this application will be absolutely of no use, lest the developer decides to fix the bug preventing it to function properly on newer versions of OS X.
As soon as you start Egis on your Mac, you will be presented with a neatly organized list of all running apps on your computer. Each application entry can be easily maximized by clicking on the left side triangle, next to the app’s name, in order to get a quick overview of all established and listening connections.
Moreover, Egis will display the type of connection the selected app has initiated with the remote address displayed on the second last tab. Just in case it’s helpful, Egis also allows you to view the network port used by the chosen app to connect to the server.
Egis also comes with built-in IPv4 and IPv6 support, which means that you can monitor both types of connections. Thus, even if an application uses IPv6 to connect to a remote address, you will be able to pinpoint the exact route to that server and decide if the connection looks suspicious.
Furthermore, if you’ve labeled an app’s remote connection as dubious, Egis enables you to quickly and effortlessly terminate that application with a simple mouse click on the “Terminate App” button in the toolbar.
In case you need to monitor all your apps’ connections in real-time and you don’t want to refresh the list manually, Egis can be configured to refresh the information automatically every 5 seconds. Thus, you always will know which application connects to which Internet address, on which port and using what kind of connection.
