Slow to get to the point. Tries to influence to download a file download manager. Luckily I got this course for free. I wouldn't purchase another pentesting or ethical hacking course from this instructor.
By Amy Gurski on 11/11/2020
I loved the content of this course. It is overflowing with practical ethical hacking tips. Because of this course, I increased my confidence in setting up virtual machines and using basic linux commands. I also got exposure to a ton of new concepts and tools like nmap, nikto, metasploit, burp suite, reverse shells and more. The CTF walkthroughs at the end were a great way to pull it all together. The abundance of lab downloads were really appreciated and made notetaking for future reference a lot easier. I'd recommend this course to anyone looking to learn ethical hacking in a hands-on way or get a better practical understanding of security as a developer (like myself).

This course is the best course someone can opt for Professor explains each topic in a very nice and detailed manner also Prof. clears any doubt and resolves any issues faced by an individual in Q&A section. I have done tons of courses in Udemy this is the best another amazing fact about this course is this is a dynamic course ,i.e new materials get added . While i started there were 58 lectures and I am now in lecture 33, took few weeks to reach here and now the course has 60 lectures ,Prof. added two more lectures . I am really looking forward for more lectures to get added to the course. I can't thank Prof. K enough for everthing .
By Manoj Narindi on 7/27/2020
Yes , it is very helpful in understanding all the concepts. A well organized course. Prof.K is a very good instructor, he clarifies all other problems we face regarding ethical hacking, even if they are not in the syllabus This course will give an overall idea, an initiation, for ethical hacking and penetration testing
By Bruce A. Luke on 3/11/2020
I love this course! Pro. K is far more detailed than any other instructor I've taken classes with. One unique feature is that he provides a in-depth, detailed step-by-step set of instruction downloadable to print and follow along with while doing his videos, and you can use will after you've completed his course. Very professional and a gets right back with you when you have a question or problem. He's an A+ in my book.

As the course title says Ethical Hacking - A Hands-On Approach to Ethical Hacking in true words. Best practical course. Level : Beginner with little theoretical knowledge can go for it. Best part of the course is CTF(capture the flag) where you learn real hacking techniques with what you learnt. Overall best practical course for ethical Hacking. Learnt lot many things with debugging so many issues.
By Eric Roman on 8/12/2019
This course offers a clear and detailed overview of each of the major security/hacking tools used in real world pentesting, and wraps it up with two capture the flag walkthroughs that show you how you can use those tools to enumerate, penetrate, and elevate access to vulnerable servers. I found Prof. K's presentations organized, well thought out, and full of valuable tips that only true experience can offer. I highly recommend this course to anyone getting started with pentesting and ethical hacking.
By Benito Suprien on 1/9/2019
I did learn a lot of interesting things, things that i had some knowledge of but not at that level and really learned a lot of good techniques. Well! about what could be improved, i do not think anything needs to be changed at all. Because , Prof. K was very professional, responsive, explicit and the explanation was very clear. In fact, i really appreciated the course and will keep looking forward to other related courses soon.
By Mike K on 9/27/2018
I think this course is awesome! I have taken other courses and this one helped expand on what I have learned in those courses. But at the same time I think it is very accessable for someone who is just starting out. I think this course also provides a lot of "replay value" and by acquiring the methodology not just the particular keystrokes as followed in the course will provide a good springboard for anyone moving forward. Thank You Professor K!
