A more in-depth concept can be included in the course and provide a reference to open source tools/technologies so young and aspiring security professionals can gain more out of this course.

Instructor was very good the first week of the course. Later on, it seemed to me he was only reading the material, without interest in really explaining the material. I have had to watch many third party videos to understand the same material he was reading out loud.

Far better to take Ed Amoroso's courses over at NYU. This is an outdated, rapid-read course that seemed to have little thought other than rattling through a pile of concepts. Little actual teaching.

A lot of "Hey, this is what this is called" but very little substance. I feel like I barely learned a bunch of terms but was not challenged to put them to any use until the very last assignment.

Lots of words thrown at us, but basically no hands on activities to implement anything. I don't feel like I actually know anything useful from my time here.

The information presented was great and I feel that I learned a lot. But, no employers seem to care that I have this certification at all.

Information is not well presented and visual aides are pretty much non-existent. The supplemental readings are not very useful either.

If you know what you're doing it's a fine quick review. If you don't then it's a morass of too little and roo much at the same time.

I think that with some graphical guidance the topics could be covered more easily. Maybe some real scenarios and diagrams can help.

the instructor was using too many analogies too fast. It was very confusing with the terminology and the speed it was coming.

More hands on learning should be incorporated in to the courses. Providing a better skill and knowledge base for learning.

cours avec trop de paroles, trop d'informations théoriques, et peu de compétences pratiques acquises au final

It was more theory. It would be better to do some practicle thing that we learned as theory.

Good for someone who is a self learner and would like minimal hands on.

It is just a primer. This will get you a job in the chat-box helping people perhaps. Very unhappy worst $40 I ever spent. I have had zero job responses even from employers since taking this course. If Coursera can find me a job in this field granted the chat-box is all it qualifies you for then I will re-write this review.

The course severely lacks visual aids and it is delivered in a robotic fashion that is not inspiring nor clear. At times the course felt like learning "vague security concepts" from an audio book. This is not how IT courses should be presented or narrated. The course format needs to be revised from the ground up.

They don't give you the professional certification promised when you complete the courses. Don't bother. These courses will do nothing to advance your career or education.
