  1. The teacher explains very well(Where to look, how to exploit, and why this happens). This course saved my life:)
  2. Thank you so much. This course has helped me understand windows privilege-based escalation, and I just wanted to say you rock. Thank you so much, Pawan, Sir.
  3. Fantastic. Straight to the point. No padding is needed. Very worthwhile
  4. They provide a real solid class that focuses on ethical hacking and cybersecurity. I enjoy the PDF slides that go along with style. Looking forward to the Linux version of the course.
  5. Great course obvious and practical examples step by step
  6. I learned a lot from this and the Linux courses. Great for anybody who is doing the (CPENT). 🙂
  7. Absolutely no fluff — each lecture tells you a quick overview of what the vulnerability is, and then the instructor SHOWS you how it’s done. The “how” of each exploit isn’t super deep but good enough to get your feet wet.
  8. It is an excellent course that helps drive home the concepts on Windows.
  9. A pretty good TLDR or windows privilege escalations for an OSCP style exam
  10. This course and the CCNA are the best IT courses I have ever undertaken, bar none. There is so much information, clearly and methodically delivered here. It is honestly staggering.
  11. This course is entirely fat-free. There is zero waffle and padding. One 16 minute video has taken me the entire week (of a couple of hours each weekday before work) to get through properly by watching the video, doing the practical, and taking notes to add to the .pdf.
  12. I really hope Essential Infosec considers doing more ethical hacking series’. I would particularly love to see more little specific and focussed tutorials on things like SQL injection or others.
  13. I say all this as someone who was a teacher for 17 years before moving into cybersecurity. This is the best teaching material I have ever seen.
  14. Fantastic course with SO much information! Thank you so much for taking the time to make this course!
  15. I am preparing for the CCNP exam, and I would like to recommend this course to everyone. The author made the concept very clear in just a few weeks. Obvious and good refresher pointers for (VAPT) students
  16. Great course for Windows Privilege escalation. It covers a lot of topics. The instructor explains the concepts very clear. The resource and the material are fantastic!! Thanks, Essential Infosec.
  17. Excellent content with good examples, overall a great course, thank you! For feedback, I think the slides could be a little more appealing, and it’s also hard to focus if they are just read
  18. Amazing course! I would highly recommend it. I am a heavy Linux user, so it was great to get a little deeper with Windows.
  19. Great course, Now I’m confident that I can go for CEH! You can see that the instructor is a professional. Highly recommended!!
  20. I’ve been looking for a good tutorial on Windows prices for a while. The methods are delivered in a clear and easy-to-understand way. I can’t wait to try these methods out in some other environments.
  21. This course has the perfect mix of technique and background context. There is a lot to digest. Some of the techniques will require practice and further digging, but I could put this content to use within the first day.
  22. This course is laid out nicely and simply. I was tipped off about this course from somewhere on YouTube. Glad I took heed.
  23. The good: I strongly suggest this course. It covers the basics of Windows privilege escalation neatly, concisely, and in an easily understood way. The price is more than reasonable for the content, and the author is friendly and seems to respond to concerns from students.
  24. The solid and clear structure of the course makes it so easy to learn you’ll be escalating your privileges before you know what’s happening.
  25. This course focuses on the meat of privilege escalation; if you are at the stage of being a very early beginner (unfamiliar with networking, common tools, not entirely comfortable with the command line, etc.), this course can still work for you. Still, you would likely need to pause and take the time to learn these things as and when required.
  26. Thanks to the logical structure of the course and subject matter. It was readily apparent, and this aided in my understanding of the topic
  27. You should be very proud of your work here, and thank you for making it such good value for money.
  28. Excellent content to learn about windows privesc for ethical hacking & Beyond !!!
  29. Excellent pacing and content. Good overview of local privilege escalation for a windows host.
  30. Absolute legend of a man!!! The course has helped me massively with my CEH journey. All I can say is buy this course & the Linux course!!
