Wireshark is described as 'Foremost network protocol analyzer with multi-platform support, deep protocol inspection, VoIP analysis, and extensive file format compatibility' and is a leading network analyzer in the network & admin category. There are more than 50 alternatives to Wireshark for a variety of platforms, including Windows, Linux, Mac, Android and Web-based apps. The best Wireshark alternative is tcpdump, which is both free and Open Source. Other great apps like Wireshark are CloudShark, NetworkMiner, Proxyman and Ettercap.
