EDR Internals Course
The courses are very advanced and the tutors express their subjective opinions which awesome, especially in the era of AI where personal opinions are threatened.
The support team is also very helpful. I had some issues with my invoice and they helped me to resolve the issue.
In two days the issue was fixed.

Thank you for the feedback! Thorough and well organized is exactly what we aim for, so it's great to hear it's landing that way. Hope the course serves you well!
Pavel doesn’t need an introduction! I’m currently taking his Windows Internals Master course, and I’m learning heaps in every single lecture.
This course is thoughtfully designed, well-structured, and clearly delivered. I’ve already made up my mind to take another one of his courses, Windows Master Developer. I highly recommend Pavel and TrainSec to anyone who wants to level up their skills.
Also, great customer support. Mikey responded quickly to all my queries and was super helpful.

Kapil, thank you for taking the time to share this feedback.
We are glad to hear that the Windows Internals Master course is delivering value in every lecture and that the structure and clarity are helping you progress effectively. Pavel puts a great deal of thought into making complex internals practical and approachable, so your comments mean a lot.
We look forward to having you in the Windows Master Developer course as well, and we appreciate the recommendation of both Pavel and TrainSec to others looking to level up their skills.
I bought malware analysis on steroids bundle .Very well structured learning paths. Everything you want is there. Your ready to use VMs , clear instructional videos and your exercises. Highly recommended! Guys on Trainsec do some awesome stuff to keep you up to date. Also they give you access to the material for lifetime! Not like other certifications or learning paths that you must pay every couple of years to keep up to date or you have timeline to complete your lessons. Just one warning. These paths are for serious people who want to learn for real. Dont expect mumbo jumbo and easy stuff. These guys do tremendous job on their courses and their lessons really help you to raise your pro level. This doesent mean that if you are on entry level you cant do it. But you must commit yourself.

I started the course a month ago and have completed three lessons so far. Each lesson is packed with valuable knowledge, hands-on exercises, and a wide range of concepts and tools. To make the most of it, I summarized each lesson and review them regularly. The content is of a very high standard both in depth and in practicality. Combined with the practical labs, this training is giving me the tools I need to become a skilled vulnerability researcher.
