Network Digger is a LAN analyzer that monitors and checks all the activity produced by different machines that make up that LAN, and the information moving about the network.
Network Digger continuously monitors activity, so you can make captures of all the content that travels on the network, and control it so there are no attacks from malicious spywares or hackers.
From Network Digger you can detect the operating systems that access the network, the sessions opened from each machine, the names of each machine that accesses, the ports opened, etc.
