Testimonials

This has been impactful and very interactive ~ D Olakunle
Short and precise description of each topic, liking it so far ~ Saurabh S
It was wonderful and good explanation from the lecturer. Moreover, learned new things and magnified my understanding, good job ~ Ndabezinhle
I'm working on wireless network in a big company, i have learned alot and now with better understanding ~ Caven L
All basic theory well explain & now I know where to continue to study Network Security. Would recommend to anyone who is just starting out. Tons of good information :) ~ Kenneth T
Loved the course till now! Fantastic presentation and detailed understanding of each and every point. Thank you very much sir❤️! ~ Vibek
The explanation of the OSI model is the most lucid and straightforward I've seen. Nice job ~ Philip S
Thanks so much for your very valuable training. I really enjoyed it, and appreciated that you made it fun! I feel much better prepared to deal with uncomfortable issues. Thank you for your wisdom, experience and personable presentation ~ H Afridi
The lecture is clear and easy to understand. It is is also comprehensive and it broadened my understanding of networking and security as a system ~ Megersa M
The course was very interesting about the security related to networking and related devises. This gave me basic foundation about how to handle security issues and be safe in any vulnerable network ~ Shailesh K
Hey this is Adams. As I want to build a career in Computer Network and Security, this course has increased my knowledge. I understand a lot about how I can protect myself and others from being vulnerable while using any device that can be connected to the internet, the best thing is; when I leaned about nmap command I found out that most of all ports was opened on my network. I closed them which I gained that knowledge from this course, and I appreciate the hard working teacher. He is doing great job and I recommend any student who want to build his/her career in Computer Network and Security to add this course to his wishlist. Thank you ~ Adams M
This course is great for ones who wants to learn the concept of networking in deep. My experience was amazing. As I have some sort of certification in the field of networking and system administration using RHEL, this course has been an added advantage for me. I learnt lot of new concepts and gained deep knowledge. I would definitely recommend this course to everyone who wants to learn advance concept in the field of network security ~ Shyam V
