The people to whom I have introduced this product have found it a great tool to analyze packets. Instead of troubleshooting by trial and error, they have a way to investigate, verify, and then apply a solution. Of course, to derive value from the product, you must know its features.
The drill-down available for packet analysis is great. It gives a network security engineer insight into what is going on at the packet level and enables better troubleshooting.
The Wireshark search function shows green for a correct search and red for an incorrect search. If there were a way to provide a description about what a search - and the similar ones which are available - can do, while a person is typing it, it would make the product easier to use and simultaneously decrease the learning curve.
No stability issues.
No scalability issues.
I have not used technical support.
I used Microsoft's Network Monitor, but with due respect to Microsoft, I prefer Wireshark.
Straightforward.
In order to be more intelligent about all the bits/frames/packets/data traversing your network regardless of how small or large the network is, Wireshark is a network analytic tool which provides such an intelligent information in a network.
Wireshark is that intelligent, not only for production environment alone but also aids study about the packet fields that may exist in any type of packet header of data flowing in your network. to view how all the classes of QoS marking in a packet are and can be used to also sniff packets during reconnaissance phase of a network security attack.
Wireshark provides better understanding on how the bits are set for different fields in a packet header.
It is indeed a very good tool which all network administrators need to be familiar with.
