Converting into the readable format makes you able to easily understand what type of traffic is passing through the captioned network. It tells you many more things that we usually don’t see – What type of traffic is it , size of packet , connection type – port/protocol i.e. TCP, UDP or ICMP and the latency between the certain hops.

This software tool also helps you to filter the traffic if volume is larger that you are trying to capture from specific part of the network. This capture will only collect the types of traffic that you’re interested in. This display filter will help you to zoom in on the traffic you want to specifically inspect.

Yes makes you enable what wrong is going on in zeroing the problematic traffic once an abnormally have been raised in the network.

WireShark will also helps us to intercept and analyze encrypted TLS traffic. Usually for every session , browser keeps the symmetric session keys, and using appropriate browser settings, an administrator can load those session keys into WireShark and fully examine the unencrypted web traffic.

This software works in graphical to visualize the statistics. This makes an easy to present the finding about analyzing to his or her less-technical management.
