Welcome to our Wireshark Packet Analysis Instructor Led Courses!

We have been using the Wireshark packet dissector and analyzer tool since it was originally released as Ethereal.  

This is perhaps one of the most important tools that anyone working in computer and data networking can learn to use.  

Why? Because when you look at the details of the packets, and learn to read them, you learn the protocol operation at the most detailed level.  Think of what a protocol is: it is a method and predefined process which enables information to be exchanged.  We find exposing these details and studying protocol behavior to be both fun, and fascinating.

Is your focus on Data Center, Wireless, or Voice?  

There are several Wireshark courses offered below, with a differing focus for each one.  Check out the different classes below.

These classes are offered as Instructor Led classes, either online or on site/in person.

If you are looking for a self paced, online Wireshark class, we have one - you will find it here!
