The depth of the courses and covering the stuff which no one actually teaches anywhere else. Really loved the attention to detail, the resources provided.

Thank you for the kind words, Haran. I'm really glad the depth of the material and the attention to detail stood out for you. Enjoy the rest of your learning.

Windows Internals course was very good and full a great information. One thing to perhaps improve is the volume of the recordings sometimes goes up and down and I have to constantly adjust it. Hopefully you can address that in future recordings.
Response from TrainSec Advanced Cybersecurity TrainingSep 3, 2026
Thank you, Chris! We’re really glad you found the Windows Internals course valuable and packed with useful information. And thank you for pointing out the audio issue. Inconsistent volume can definitely make it harder to focus, especially when working through technical material. We’ll take this feedback on board and work on improving the audio consistency in future recordings. We appreciate you taking the time to share both the positive feedback and the constructive suggestion. It helps us keep improving.

Top quality content from world class practitioners. Highly recommended
Response from TrainSec Advanced Cybersecurity TrainingSep 3, 2026
Thank you, Pete! We really appreciate the recommendation. Bringing practitioners with deep, hands-on experience into the classroom is a big part of what we’re trying to build at TrainSec, so it’s especially rewarding to hear that the quality of the content and instructors came through. Thanks for training with us!

- simple lab setup - very clear explanations with a lot of demos - easy to ask questions during the session
Response from TrainSec Advanced Cybersecurity TrainingSep 3, 2026
Thank you, Christophe! We’re very happy to hear that the lab setup, demos, and explanations made the session easy to follow. We also believe that being able to ask questions and explore things live is an important part of technical training, so it’s great to hear that this worked well for you. Thanks for joining us and for taking the time to leave a review!

Pavel is a great instructor It was a brief course, but still detailed enough to give you good knowledge in what matters more. Slides and flow was well organized. Thanks !
Response from TrainSec Advanced Cybersecurity TrainingSep 3, 2026
Thank you, Yaniv! We really appreciate the kind words about Pavel, the structure, and the slides. The challenge with a short masterclass is finding the right balance between depth and time, so we’re glad the session managed to give you useful knowledge without feeling too rushed. Your feedback means a lot to us, and we hope to see you again in one of our deeper courses.

The content was great and Pavel’s delivery of it was very good. Pros: - He was able to weave answers to Chat questions on the fly. - it was easy to follow along with his demos - he has world class knowledge of Windows and is approaching that in his Linux knowledge - learned about Linux Mint distribution which I will look into - loved the way he explored learning about processes, threads with ways to view them via the virtual file system. Cons - time didn’t allow for the last topic on boot, services, etc. I understand that he’s still working on the larger Linux internals course, of which this is a taste. - some explanations could be tightened up. Sorry, I didn’t note which ones.
Response from TrainSec Advanced Cybersecurity TrainingSep 3, 2026
Thank you, Bob, for the detailed review. We’re really glad you enjoyed the content and Pavel’s approach, especially the live demos and the way he incorporated questions from the chat into the session. You’re absolutely right about the timing. We had more material than the four-hour format could comfortably accommodate, and the boot, services, and related topics ended up being the part we couldn’t get to. That’s something we’re taking into account as we continue developing the full Linux Internals course. We also appreciate your note about tightening some of the explanations. That kind of feedback is genuinely useful when refining the material.

I like the windows internals master course, it is very detailed and gives me a good understanding of how windows works. Also great support from the team for account related issues. Amazing SLA.
