No. Just no. Terrible course quality. Sound is inaudible. Not a good option for a complete beginner. I finished it, however not worth your hard-earned money. You will get better help from a Youtube tutorial. If you're only doing it because you need some form of proof that you understand some cybersecurity concepts then this course is fine as you will earn certificates. You will also walk away with no real-world required knowledge of the cybersec industry today(2022). Course consists of a lot of self-read assignments where most topics and concepts can be overwhelming for someone who just stepped into the cybersec industry. Some slides are copied from other resources and not original. Some slides are also very hard to understand as the words are all over the place. Slides are eddited poorly and you have to make sense of it all on your own. For some this might not be a problem but for some students this can be very frustrating because understanding this topic is crucial. Best of luck to you if you decide to proceed in this course. Just breathe and remain patient till the end.

Very poor arrangement of this course. As the name of this course, like, "professional", but course arrangement like, poor videos, poor visuals at presentation, very very very poor verbal communication skill, very very very poor and poor sound quality like totally unclear vocals and talking styles. Very disappointing course this. But yeah, the information of this course is very useful. The matter is, It was very hard to get those information cause poor quality of course and course arrangement. I would like to give an example to see, "how should a professional course looks like!". yeah, see google, see their professional course's videos. I have completed almost 3 courses from Coursera and this is the worse experience. Very disappointed. What I want to say that, re-arrange this course and upgrade the quality thus anyone can easily get this. I mean at least clear vocal and talking style.

This course is incredibly outdated with very confusing information being given in all the videos. I'm only on week one but every video has improper grammar and the information being taught is very confusing. The audio matches the subtitle summary under the videos so its not that.

This is a Cybersecurity course, which a very fast paced, fast changing field, that is using information and stats from 2018.

I do not understand how you can charge $40 a month for confusing and outdated information. I have submitted multiple reports showing how confusing the information is and I hope they are seen.

I dont plan to continue the course because I don't have confidence that I am being taught information that will be up to date, accurate or even relevant to the field today.

Technically, the content of the class is good, but the audio presentation is very hard to follow since the speakers talk very fast, very speer-of-the moment and with very strong accents.

Also, what had me frustrated that in the four major final quizes at the end of each week, I was only able to review my mistakes or lacks in one week. For all the other weeks everytime I clicked the button to review the quiz's mistakes it just led me to a blank page, which was not very helpfull. Under the same circumstances it happened that it didn't matter how I changed my answers for the questions I was unsure about, I remaind with the same grade, therefore I failed two assignments left to not knowing why.

As someone who majored in Computer Science, and has a little bit of Cyber security experience, this course was very basic, I do not recommend you take this course if you have a similar background.

Now, when it comes to content quality, I have seen much much better. This is the same for the organization and presentation of the course's contents. I was extremely disappointed with the quality I was presented, given that it's IBM who's making this course. I found myself STRUGGLING to finish this course and get on with better ones.

My advice: There are better courses out there, and you should take this course only if you have no (or extremely limited) knowledge of the basics of cyber security.

This is really not very good. You get to listen to non-native English speakers drone on for about 5 times as long as it takes to read the transcript for the video. There are some basic Power Point slides that you could look at, but this information is so general and long-winded that you're going to be a lot more efficient and a lot more informed using other resources. I made it through the first 45 minutes or so by reading the transcripts and feel that I learned very little. Maybe the rest of the course is better, and you're welcome to find out for yourself. I can't understand why professionals can't do a better job of presenting information than is found in newspaper articles.

I could not understand the instructors enough to comprehend and remember the lessons taught. this is the first time I felt like I was wasting my time with a course. there was no point in continueing if I couldnt grasp the first part of the course. I could not finish as the comprehension just wasnt happening. i figured it is prolly just me and have since given up on my goal of becoming a cyber security worker. very disheartening cause not sure if I just too dumb to learn, or the course is just terribly done. as I have had sucess with other courseds I assume its me, so i guess I'll just forget about this plan of mine.....

Oof so many audio issues, difficult to make out words, the s sound is overly amplified, hammering heard in the background multiple times, visuals are basically a repurposed powerpoint presentation over zoom, poorly transcribed subtitles, subtitles cover the visual content / not optimized for subtitles, poor video quality, lack of variety of type of content (lots of video instead of video sometimes and text at other times), poor grammar on the part of the speaker, terms not covered well despite being an introductory course...I will probably not go into cybersecurity as a result of this poorly made course.

I learned from this course an important lesson: that experts on a field may not necessarily constitute to be instructors. This course needs a review of the presentation and the flow of their information. The knowledge is good, but it is repetitive and doesn't build and complement each other. It seems like the instructors are doing their own lessons and don't know what the other instructors are doing. It would be essential to partake in higher-quality recordings and communication practice. It seems that the instructors often get their sentences mixed up and so makes the flow choppy.

Avoid this course. I learned more in 1.5 days on the Georgia State university Foundation course than from 2 weeks on this one. The presenters spoke unintelligibly, and when it was possible to interpret what they said, it was usually not relevant to cyber security. The subtitles were machine derived and had not been checked, so even the subtitles could not make sense of what the presenters said. The presentations were badly set out and planned, with the presenters changing their mind about what they wanted to say half way through a sentence. All in all, a waste of my time.

I tried to get through the course, but the poor audio quality and rambling of the instructors made it very difficult to learn. Poor audio quality - not a problem, I can just read the transcript. But the rambling made it hard to understand the material by reading. I could barely understand the speaker. I was very surprised given the high rating of the course and hoped the instructor might change, but after partway into Week 2, I looked through the comments which confirmed my experience, and decided to give up and find a course elsewhere. Very disappointed.

This course was put together horribly. Things were poorly explained, some links to the reading brought up error codes (obviously old information), there was a serious lack of proof-reading...all of this made it very hard to focus. I ended up reading as much as I could through most of the material instead of watching the videos and I barely passed the quiz material. I ended up googling most of the information on my own. However, some of the links with resources were very helpful and allowed me extra reading to get a sense of what was going on in the world.

The audio and video quality of this course is abysmal. It sounds like the lecturers called in via landline, and the slides are often so blurry that you cannot read their content. The course is so superficial that you basically only learn some terminology. After this course, you will not have gained any applicable or employable skills. This course is produced by IBM, one of the biggest tech company, you would expect they could do better. I can only hope that the following courses in this specialisation are more carefully produced.
