NetworkMiner is a popular network forensics tool that can parse pcap files as well as perform live sniffing of network traffic on Ethernet and WiFi networks.
NetworkMiner collects data (such as forensic evidence) about hosts on the network rather than to collect data regarding the traffic on the network. The main user interface view is host centric (information grouped per host) rather than packet centric (information showed as a list of packets/frames).
NetworkMiner has, since the first release in 2007, become a popular tool among incident response teams as well as law enforcement. NetworkMiner is today used by companies and organizations all over the world.
