Mac: Ever wondered where your applications were sending and receiving data from? Private Eye is a real time network monitoring app that shows all of your live connections from all you open software, and includes where they’re sending data to.
Private Eye displays all connections your applications have to the web, the time, and the IP address connected to the app. You can then filter those results by app, or by incoming and outgoing traffic. Private Eye doesn’t have the power to alter any of these connections once they happen, but it does give you enough information to know if an app is connecting somewhere it shouldn’t be. If you’re interested in security, or you just want to track where your apps are sending data, Private Eye is a free utility that’s easy to use. If you want to stop those network connections, we like the lightweight firewall utility Radio Silence for preventing your apps from phoning home. Radio Silence is developed by the same developer as Private Eye.
