very useful course more content .But audio is not good sometimes you need to increase volume more .

I enjoyed the course :).

This course helped me a lot in learning about various cyber attacks, malware, cryptography and many more skills like this.

Course is good, but the quality of sound and sometimes sound coming before picture. But the quality of the course is good

The course was good. I have learned a lot of new things. But after completion of the course i haven't received the Badge.

The course itself is very informative, but the proof-reading/subtitles have not been done very well. Good course overall.

course is very informative but audio in some videos is no quite good, replace it asap so other students will not suffer.

Sometimes the sound quality was really bad, hard to hear out the words, but overall it was a great course of the basics.

The course is very interesting and well constructed, but there are some videos whose audio is very noisy and inaudible.

j'ai tellement appris sur la cybersécurité en ce cours ,avec beaucoup de nouvelles compétences acquises merci coursera

Very informative, though sometimes the questions for quizzes would have the wrong answer listed as the correct answer.

It was a wonderful experience!Although some of the audio was not audible.Nevertheless the course was worth the while.

no offense but lecturers need to improve on their speech but overall plenty cybersecurity related topics were covered

Content was good. But audio recording from Instructors are not very clear as we can find in other learning platforms.

This is nice course for me I am learning lots of things about cyber security key ,firewall and many others ....

the Audio quality was very low and the content was too much brief and was not enough to understand for a beginner ,

audio quality must be improved. Also, it would be meaningful to have access to the course references, such as slides

Great material and depth of topics covered. However the language and captuions made it challenging to keep up with.

All basic knowledge that we needed to insight into Cyber Security Field. All have been Covered. and looking forword

this course was great, I like the key concept learn in this course and the examples were directlè concern , thank's

Se contempla varios temas importantes y sirven bastante para empezar con el mundo de la ciberseguridad, recomendado

The course was very insightful and interesting. It invoked an interest to learn more about the cybersecurity world.

I liked it and learned a lot but I gave four stars because I wish the teacher had a clear voice to understand him.

well , I like to thank the IBM course to bring such a amazing course , there is still some improvement required .

The course is very wonderfully executed but one thing the voice quality could be better for better understanding.

I am very happy for this opportunity given to me to gain knowledge with IBM through Coursera. Thanks very much.
