rest all is okay but he can be more indepth about network segmentation, needed to be more clearer and use easier langauge, sometimes the knowedge are so everywhere that its hard diffrerntiate which topic it is actully

By Roshan Chandrahasa Malpe on 8/30/2026

It was a good course and quite simplified, as a non tech person it did not get a few points but those might be my limitations, fully understood it when i read the resources.

By Richard Martin on 7/9/2026

It takes up tp 4(!) hours as all 23 chapters sum uo to 168 minutes, 10 role plays with max. 10 minutes each, 19 quizzes around 1 minute each and an overall test with 30 questions with 15 minutes.

By William Westover on 6/16/2026

The course is enjoyable so far, and I feel like what I'm learning could probably be helpful in the future. It feels a little slow for my taste though

By Andrew Sanders on 6/2/2026

Good introductory to Cyber Security. I wasn't fond of the AI Role Playing. Seemed a bit confusing on what the target answers should be. But that's AI for you.

By Dan Burke on 4/16/2026

This course is great for people who want to get the basics of cyber security. Rick Crisci explains the basics of what can be complicated topics very well. The visuals he uses can be a bit rudimentary, particularly when they are drawn out in real time. While these visuals could be more polished, I still got a lot out of Rick Crisci's ways of explaining these concepts, and the downloadable resources were particularly helpful to review after viewing these videos.

I would like to share my appreciation for the training session. The content was well-structured, clear, and easy to understand. Overall, it was a very informative and valuable training experience.

By Thomas König on 2/26/2026

Kurs war inhaltlich gut für meine Bedürfnisse zugeschnitten. Wesentliche Grundzüge der Sicherheit wurden vermittelt ohne zu tief in it-technische Fachinhalte einzugehen.

By Ashley CARTER on 2/16/2026

So far the course is great. The information is broken down into smaller segments, making it great for beginners. I look forward to progressing through the rest of the course!.

By K E James on 2/4/2026

Good content for refreshing knowledge and some gaps. An existing understanding of networks is helpful. It takes longer than 2hours 46 mins to digest in smaller chunks. I finished it comfortably within 2 days that had plenty of other distractions - but I am pleased that finished it! Not all courses keep me for the distance.
