Very solid course. Quick overview about almost everything you need to know at the beginning. A lot of useful links with additional material to study. Thanks a lot for sharing the knowledge, indeed!

Very little actual knowledge, first half of this course is basically a repetition of the Introduction into Cybersecurity course. The quality of a good amount of the slides is so poor, that they cannot be decrypted even in the best video quality option. Also the sound quality is sometimes so bad, that you have to read the text under the video, which in itself is also sometimes very far from what was actually said in the video (automatic subtitling / translations?) Some questions in the quizzes are very difficult to guess, especially when the questions are too vague. Other questions are simply grammatically wrong. There is also no substantial mentoring of any kind. If I were you, reading this, don't pay money for this course, at best, audit it for free and move on.

hard to understand given the heavy accents of some instructors; tests do not reflect subject matter.

This course has designed well. Need to provide presentation files in separate download file for better clarity. Also need practical works which was not there.

The first week of this course is comprised of videos from the first course in the Cyber Security Analyst certification. The videos are of poor visual and audio quality. I found the instructors very hard to understand due to their accents. The quizzes often do not reflect the subject matter. More than once, I had to select a wrong answer to pass a quiz. To sum it up, this course is sloppy and since it is part of a larger program, it would behoove IBM to rearrange this material to fit into the previous course and following courses and then delete this course entirely.

Most of the content of the first two weeks is repetition from previous course. Third week's content actually too trivial for someone interested in cybersecurity and IT technology. So, in a nutshell, this course was not productive at all and could be better. Sound quality is a little better from the previous course though.

I enjoyed learning the information in this course! I learned a lot of procdures and I understand there's much more to learn. And I'm so excited to continue learning and growing in this field.

Going into more details on Roles and Processes. But also briefly touches on the various operating systems, short-cuts and a nice week on Virtualization; that was nice!

Audio and video quality are terrible. It sounds like the lecturers dialled in via landline, and whenever the slides contain non-trivial information, they are unreadable due to coarse resolution.

The course content over the four weeks seems to be completely randomly matched. You learn a lot of vocabulary and memorise definitions, but you don't get to see a single real life example of any of these. The tests during the lectures merely check that you paid attention to the videos closely enough so that you could pick up a particular sentence or definition that is asked for.

This course will not teach you anything you could apply to real problems.

Shame on you, IBM!

I would like to rate this course a 4.5 star. The details explained in the videos is amazingly clear and easy to understand. I appreciate the efforts put by the people making this course. However, I feel that a detailed session on OWASP would have made it worthy of a 5 star rating because that is something very important for Cybersecurity which I found missing in this course.

I LOVE these courses by Coursera! Totally worth my time and patience! The modules are not that difficult. And with some clever material searching, I have had little issues passing the courses. The information seems fresh yet a small percentage of links did not work. Other than that I appreciate Coursera & IBM teaming up to offer courses like this!

Thank you!

The video and audio quality are very low, some links are broken and some resources are out of date. The one bright spot was the macOS portion, the video and audio were excellent and it was clearly created in the last year, IBM should redo the course at the same level as the macOS portion.

He visto el cuso demasiado básico teniendo en cuenta que venía del de previo. Hay material que se repite.
