The audio is not sound and clear enough.

Audio in some videos are garbage

Audio is hard to hear at times.

Video quality is way too low

very useful

to complex

I do not recommend this course unless you are starting with 0 knowledge of computers and security, and even then, you can probably do better.

TL;DR - Very poor audio/video quality, inconsistent/incorrect information in several places, and a truly bizarre mix of ELI5 and unnecessarily in-depth information (even within the same videos).

The first half of the course is all about business process (ex. ITIL) and then rehashing the CIA triad and AAA (which was already covered in the preceding course in the specialization). This part is ok, though the business process piece felt out of place and disconnected.

The second half is the idiot's overview of operating systems mixed with some randomly in-depth information about file system formats and kernels. Ex. there's a video that explains what a file is (idiot's overview) and then goes into NTFS and FAT32 (randomly in-depth). If I don't know what 'file' and 'folder' mean, I sure as heck won't be able to figure out what file system format is suitable for a single-partition 128 GB drive!

The worst parts, though, are the poor audio/video quality and the inaccurate/conflicting information and quizzes. Many of the slides in the videos are so pixellated that they're completely illegible. There is missing, incomplete, or contradictory information. And, some of the information has become outdated, so even if it was accurate at the time, it's wrong now.

Really very disappointing. Let's talk about form and substance. For the form, we have the same big problems as in the introductory training: we hear badly, so automatic subtitles contain a lot of errors. What is new is that some slides are blurry and partially unreadable. Regarding the substance, we do not learn anything really interesting about cybersecurity. There are even videos on Windows keyboard shortcuts! As in the introduction, most of the speakers are not teachers. They get to confuse you on subjects that you know very well! Much talk is very vague, commercial, or only advertises IBM products. The tests simply repeat the content of the slides, often without understanding them.

most of the lectureres are very difficult to understand so I had to read insted of listening to them. For the subject I didn't know at all, the explanations were very unclear and difficult to understand.

my most challenge is to understand what they are saying. In the intro video it was perfect but the actual lecturers are very difficult to understand. As it is a new subject for me it makes the difficulty triple.

as I have already started the course I will finish it but expected much more from IBM.

these people might be geniuses in what they do, but as in the case of teaching something in English, I find them not that good.

Very unprofessional course. You're better off going on Youtube and watching a course of videos on the basics of Cybersecurity than this garbage. Someone with an actual good working mic, and doesn't ramble on or read off the slides is capable of teaching this better on the internet somewhere else for free than this.

AGAIN......Extremely poor quality video and audio. Very surpised at IBM for delivering such poor qaulity content and also dissapointed in Coursera allowing such poor quality content. I will would not recommened this course. Save your money and hard earned cash.

This course is put together well. The quality should be much better, especially since there is a cost. Also customers should be clearly told that this are certificates, not certifications and there is a difference. Certificates won't help you gain employment.

I continued with the second course in hopes that the quality might improve. I was naive. The course material is repetative. The course sound quality has not improved. The same instructors with horrible sound quality were used for this course as well.

This course is horribly boring. It feels like it was created in the 1980s. There is no entertainment value and the audio is terrible. I can barely understand the presenter and I'm just looking at some slides.

sound quaility is aweful not what i would expect from a big name company like ibm. Often times i had to rewatch video and it lost my attention. audio sounds if they are recording in their basement. Terrible.

good course. my problem is coursera is scuffed and i did not receive my badge for this. i've tried redoing the course and nothing. fucking scammers trying to squeeze another month out of people.

First week is mostly repetition of the previous course, then most of the other contents are only about bullshit terms, while the very few real content was on a very basic level.

Terrible. Can't understand speakers. Even the written translations have "inaudible" for certain areas. Are you kidding?

It was one of the worst course ever literally disappointed by IBM course designing team... IT CAN BE BETTER !!!!

I took the course for free and now it requires payment for a certificate why...........

I thought the course will be very practical. I was just reading throughout

Worst course ever on coursera. Highly unprofessional and unpractical.

Poor audio, random training videos stuck together.

Bad audio, bad video quality

Low quality audio and errors
