The concepts are explained in detailed and at a slow pace.The course was very comprehensive and easy to understand. The Instructor explained each topic in a informative way that won't make us confused. Thank you so much for this great course!

By Vincent Padilla on 1/11/2021

I've taken many courses from many instructors in real life, and adjusting to accents is just part of the deal. However, I'd imagine for someone who does not have my experiences, this gentleman is a little hard to get used to. Still, the content and delivery seems very good and I've already learned a lot of what I intended (a networking re-visit/crash course) from this course.

By Sofia C. V. on 12/8/2020

It's a very interesting course. However, the instructor just read the PPT without adding anything much of value. It's also a bit outdated and never mentioned the threats of AI (honeypots) and Quantum Computing (Brute force or Encryption). I asked the instructor some questions but never replied.

By Shay Kozokaro on 10/30/2020

It is good, but only deals with the general concepts, so it's a good starting point for a beginner. The course name "..from scratch to Advanced" is a little bit misleading, since as I said - this is an entry-level course, which may be very good for non-technical personnel. Thank you!

By Luke Newell on 10/29/2020

A good theory based introduction to some basic cyber security concepts. There are some parts where the presenter tends to speak a little fast, making it slightly difficult to follow, and the quiz sections could be a little more comprehensive and thought provoking. But other than that, the course is well produced and worth checking out if you are new to cyber security and want a quick and easy introduction to important concepts.

By Adams Muhabura on 7/31/2020

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 use any device the 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 I gained that knowledge from this course, and I appreciate the hard working teachers they are 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

By Shyam Vagadiya on 7/16/2020

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.

By Shailesh kumar on 6/11/2020

The course was very interesting about the security related to networking and related devises. This geve me basic foundation about how to handles security issues and be safe in any vulnerable network.

By Robert Bernard on 10/16/2019

This course is probably not what I was looking for. It was oriented primarily toward security specialists for business/office networks. I really only wanted to know about home network security. Also, I'm more interested in the tools at my disposal and how to use them. Some of that was presented, but not enough. So I probably just picked the wrong course, I'm sure the info was totally appropriate for a security specialist.

By Collins Chima on 6/9/2018

I had learnt the basics in a network system, its structure, components, devices,security and its application in the real world. I would like to further dive deeper with more similar courses and expand my knowledge in this world of networking. It would be of more benefit here with the instructor providing more real world scenarios of the concepts i just learned.
