Course Description

Welcome to The Complete Ethical Hacking Course!

This is by far one of the best ethical hacking courses I’ve taken. The instructor explains complex cybersecurity concepts in a clear, practical way. What I really appreciate is the hands-on approach; everything is demonstrated step by step, making it easy to follow, even for beginners. At the same time, the course goes deep enough to be valuable for intermediate learners. If you are serious about learning ethical hacking and penetration testing, I highly recommend this course. It’s practical, well-structured, and worth every minute. Thank you very much!

Instructions for installation on Apple Silicon-based chips (M1 onwards) are not correct or do not work. By following the course, wasted a lot of time initially with Virtual Box instead of UTM, something that should have been highlighted and earlier on. Had to use ChatGPT to complete the installation. Explanations at key decision points are often omitted, which affords little learning for the student. Course content is too much "click what I click" instead of giving context, comparison of any options, explaining reasoning for choices. (Will update this review if rest of course improves.)

By Mindaugas Vezelis on 6/1/2024

That's a realy good course on ethical hacking, which I enjoyed very much. The tutor introduced multiple (plenty) command line tools including some GUI based. What I came across here, it opened my eyes on how it is easy (overall) to hack a computer. It is great that the course taught Python scripting in the context of security. I see that Python is easy language in comparison with Java, for example. I would highly recommend such course... No regrets from my part.

I thoroughly enjoyed well crafted material taking the modules into a step by step learning process. Mr. Atil's explanation was very good and the fact that most of the concepts had to be repeatedly used in subsequent modules, it was well designed so that what we learnt also got brushed up as we moved on. Overall good .. Thanks Mr. Atil and Udemy!

By Kamruz Zaman on 7/5/2020

A detailed and structured course giving a thorough explanation of ethical hacking. The instructor is very knowledgeable and explains everything step by step. What I particularly like is that he explains trouble shooting techniques if something does not work. Other instructors assume everything works but that never is the case. Furthermore, most importantly he responds to questions and gives feedback. Some of the explanations drag on and you get lost and forget What he going on about. I managed to get most of the tutorials to work, but sometimes you follow the explanations exactly as shown and you get different results.

By Mattia Micco Iraci on 3/28/2020

Good comprehensive course to have a wide view of what it entails to be an ethical hacker. Some code presented could be improved but overall satisfied from what I got from this course

By JR Kenth Nacalaban on 2/19/2020

Amazing course! Not only he tells you what to do but he encourages you to practice the basics and what you have learned again and again. So far, I haven't raised a single question even though I'm a newbie in this field because the course gives you almost everything you need to know and solve the problem. I'm still halfway through the course but I'm learning so much already.

By Martin Ivan Marmolejo Anguiano on 1/9/2020

I would like to make a review about for this course, sorry for my poor English. I really enjoyed this course it took me around three weeks to finish it. I learned a lot of knowledge like: Wireless Atack, post connection Atack, social engineering, exploit on browsers, external attacks, we made a fake game, XSS, SQL injection, ethical hacking on python and more. I would like that the teacher adds some lesson about msfvenom due to I consider is more effective against antivirus. The resolution and audio from the videos has a good quality, I Think that person who said that the resolution and audio is bad, it's because they watched the lesson on a cell phone. English isn´t my native language, but I really understood to the teacher because her English is clear. Thanks for the course. I will recommend to my partners in the school. Greetings from Mexico !!! :)

By Sarmad Ali on 10/20/2019

This course was quite extensive and strategically designed. I would like to thank the instructor (Atil Samancioglu) for his valuable efforts by designing such an interesting course, not only that but tremendously explaining each and every bit of the course in detail. In addition, he had responded on every queries I had within 24 hours time which adds a great value to this course. I would recommend this course plus the other courses he is teaching on Udemy. Thank you Atil Samancioglu and entire team who was involved in designing and delivery of this course.

By Leigh C on 7/31/2019

This was an excellent and enjoyable course with a knowledgeable course tutor who made all the concepts clear and easy to follow from start to finish. Great value for money with a lot of useful content that I will be coming back to in the future for reference. The ethical hacking section is followed by the python coding section to show how bespoke hacking tools can be written. A great start to Ethical Hacking and Cyber Security with guidance on how to take things further to expand knowledge an career beyond this course. Highly Recommended for anyone wanting to get a good grounding in this area and importantly how to protect against malicious cyber attacks.
