A great course, it covers the subject in a very accessible way, leaving no doubt as to its understanding.
18 November 2021
Like all of David's courses, this one is fantastic. He is one of the best course creators on Udemy. I highly recommend this.
14 November 2021
Great course and I am absolutely recommending this to my friends, learned a lot during this course. The concepts were very well explained with clear examples. The instructor also replied in a fast and clear way. Terrific course
10 November 2021
The instructor appears to be concise and direct with his knowledge, in the beginning. I will be able to give more accurate feedback at the end of the course.
7 November 2021
Instructor is excellent, speaks clearly and in a way that's easy to understand. Besides using wireshark there is a ton of extra information regarding network protocols. My only criticism is the quiz questions in sections 7 and 15. He gives us screenshots from wireshark and asks to identify the protocol, but any and all indentifiable characteristics are blurred out. Unless you are a seasoned wireshark user there is no way you'd know the answers. Answers are provided but with no explanation... just an image of the packet with the blur removed. Not very helpful.
25 October 2021
So far I love it. It is my kind of way to learn things, detailed and also getting a little into details that are not just what to click and what happens when scenarios.
23 October 2021
I was not prepared for the linux peace, I basically had to install a VM with ubuntu to follow but I wanted to use mostly on windows environment.
22 October 2021
The course was pretty interesting if you are looking for CCNA topics, but isnt really guided to Wireshark
8 October 2021
Great course! David is an excellent instructor who motivates you to excel. I would recommend this course to anyone
5 October 2021
Great presentation and with very clear instructions! The course is well structured, with lots of examples shots taken from the Wireshark. I believe this will help the students in understanding all the features found in Wireshark, and what they can do to make network analysis much easier.
1 October 2021
very good explenations and easy to follow the pcap file didn't work on my wireshark. internet file was a little different but still able to follow
30 September 2021
Good basics of server client communication. Explaining how OSI model fits into the capture. Showing how to export image to desktop.
2 September 2021
David is one the best teachers I have on Udemy. Constantly learning from him. Wish him all the success now, and in the future.
31 August 2021
The teaching could have been a bit more simpler- sometimesthe amount of information is overwhelmingand confusing, otherwise good materials
25 August 2021
This course is very good & informative. the best course i had taken in Udemy. Instructor is very super. recommend strongly.
