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.

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.
