Quick scan resulting in detailed reports

Through WinpCap or Microsoft Network Monitor, the WhoIsConnectedSniffer app is able to vigorously detect traffic. The driver kits simulate a packet listener that processes each of them.

Once done, a comprehensive report detailing information such as IP and MAC address, computer/device name, description, operating system, network adapter producer, detection count, identified, protocols, down to the first and last date it was distinguished will be flash in the application’s interface. You're free to export it locally to a text file or an HTML report.
