The speaker is shouting and there are kids srcreaming in the background, speaker obviously shouting to cover up his kids in the house. Terrible!!! Waste of money and would not buy another course from Udemy ever again.

The cadence of the narration is somewhat distracting, but the material is very good. It's sometimes difficult to follow the demos on screen because of the font color (dark) against the black terminal background. Overall, worthwhile.

Good course about Linux security and hardening but It'd be great to include SELinux, Fail2ban or more advanced tools like Advanced Intrusion Detection Environment (AIDE)

The course is complete and very informative. The explanations are clear and concrete and the examples are indeed useful. It was a real help for me to complete my knowledge about the subject. Good work!

I guess he starts speaking slowly but accelerates from the middle of the phrases and then become difficult to understand him. So, I suggest him to keep the pace, trying to finish the phrase as the same pace as started.

Well laid out course with excellent demos and explanation and does a good job walking you through the hows and whys of securing your Linux system. He made it easy to follow along and understand the concepts, even for someone like me with a Windows background and little Linux experience.
