I learned so much about security and encryption protocols! super useful!

Good content.

The content is good, the instructor is great - although mainly reading the text most of the time instead of explaining the stuff more fluidly.. I only gave 4 stars because the way the course is presented, there's a lot of theory, which is good, but the application of all this theory through practical examples is what's missing. I think is a great initiative by Google, and the course provides a lot of understanding of what is going on with all the security protocols and cryptography, but it really misses on the practical aspect, lacking exercises with real world applications of the content presented, which are as important as the theory itself. Thank you Google for the initiative and hope I could give you and all the people who's wanting to take this course a little to think about.

Many technical issues regarding labs and no explanations or feedback for important and critical issues.

This was brutal. It's a guy reading acronyms and definitions, and you as a student desperately trying to take notes on all of it. This was my least favorite of the 5 courses by FAR.

This was by far the hardest module to finish, but I did it and I especially would like to thank Coursera's support people for that. They rooted me on, and kept telling me not to give up. Thanks!

The course contents are really good but I didn't feel that the final assignment fit the contents .

Never had some many technical difficulties and this has been out for a while now.

This course was different than I expected. Perhaps I see it as a bridge course from this excellent on-line well-balanced interactive video and hands-on learning tool to what it is like to sit through often text-based lectures about material you just need to learn by rote. So, for me, its 2 main strengths are: 1) prioritizing vocabulary needed to communicate security issues as the fundamentals of cryptography and protocols are also taught and 2) the final exercise question was an opportunity to summarize fundamental suggestions on how to improve security for the many situations where next-gen tools are not affordable or (possibly) relevant.

My recommendation for the ending might be to recast the content you wanted to be sure everyone knew cold into the familiar multiple choice tests you have relied on throughout this 6-course course. Then, add in the rapidly changing VM security solutions that I discovered while researching what I took to be a perfectly valid real-life assignment: how would I help a growing 50-person plus business (or myself) make best use today of dollars invested in cybersecurity? It was a fun and eye-opening look at both the cutting-edge tech coming down the pike and also how this will increase the need for generalists and provide tools to partner differently with old-school IT sys admins. It seems like a big shift and I'm still processing what this implies about training for cyber workforce readiness. I do feel this might have been an opportunity to wrap up the course on a different note.

Regardless, I appreciated the authenticity and different teaching styles of each of the teachers in this course sequence. Each in their own unique way lived up to being an aspirational role model for the many young people for whom this course will be a game changer.

I learned TONS in this class and all the classes offered. I am totally grateful to Google and Coursera for making it possible, and I want to extend gratitude and thanks to the instructors who taught us and their support staff(s) who did the invisible behind-the-scenes work that the students never saw. I had a great time working with my student colleagues, especially those who finished with me.

Dear Google & Coursera

This was the most profound course for me, I was able to learn more in-depth about IT security. In fact this course made me want to pursue a masters in Cyber Security. Thanks you Google and Coursera, for making this possible for people like myself who has a passion for IT but live outside of the united States of America.

Thank you

Content is good, but unfortunately I am not able to finish my tasks in LABS, since many links are broken, thus I cannot finish and get the certificate finally. It really prolongs my job search.

Course 1 and 5 are probably my favorite of the courses because i feel i learned a lot in these two the most, all are great i just really wanted to learn more about security which was course 5

Excellent and informative

Excellent

the concepts and terminology covered in this course could be explained in a simpler better way. I found some websites and youtube videos which explains these concepts in a simpler but more effective ways. Like all other courses in this certificate program, some materials needs to be updated. looks like they have been neglected for 3 years and it is a really long time in IT industry.

I was really disappointed by Google since I was expecting a much better job from them. It is clear that they didn't assign enough time and resources for this certificate program .

Lastly, I would like to thank all my teachers . You guys are awesome and very enthusiastic about teaching and motivating learners. You guys can do only so much with the limited time and resources you were given. Best of luck and God's blessings in your life journey.

Thank you again.

Wasn't taught very well, and the assignments weren't very hands on at all so it's very difficult to learn anything at all. Wouldn't really recommend using this as a way to get a job, maybe just to see if you want to go to college for IT. The concepts were very lightly touched on and didn't really provide any real information, but even if it was, as I said above the course wasn't taught well so you wouldn't have learned much anyway.

I have fairly bad ADHD and I cannot focus on this corse in the slightest. How material is presented is so incredibly bland and uninteresting its hard to retain any information given without rewatching the video 3-4 times. Maybe actually show software or hardware related to the terms you are teaching to give a grasp of what they actually are instead of just reading out the anagram.

I'm aware this could be very much a me problem but this corse in particular was just to difficult for me to retain anything with the amount of anagrams and terms given out each video that did not have a clear enough explination. I had to google terms and I instantly found a clearer way to word it multiple times.

Honestly, I'm very confused how this course is so bad compared to the other courses in this certificate program. When I finished the other courses, I felt accomplished. I felt like I learned so much about something I knew nothing about. With this course, I feel like I just learned a bunch of vocabulary words. In no way did this show me how to implement any of these acronyms to make a company securer. I have no idea what to do to set up a sucure network, how to install firewalls, what a firewall even looks like. Unbelievable.

Pretty fair course, and enjoyable overall program. This particular course has its strengths and weaknesses, but it's still taught in a manner that is understandable. Not as hard as some of the other courses and anyone can do it without needing to take the ones before it. I also liked that this teacher had a noticeable sense of humor. It added a nice touch to the sea of technical facts.

Some weaknesses: Some of the long videos give far too much information to take in at once. There's one 9 minute video where literally every single word matters. It was very stressful to sit through. Another big criticism that other reviewers and me have is that many quiz questions are ambiguous. There are numerous instances where some answers actually are correct, but they're marked as wrong if you select them because they're not what the particular question is looking for. This led to some very frustrating instances of getting questions wrong when they would otherwise be right. I saw two other reviewers complain about this before I took the course, and I didn't think it would be that big of an issue until I took the course itself and saw just how prevalent it was.

I still give this course five stars because nothing is perfect. I learned a lot and had a great time obtaining my IT certificate. I will absolutely look into furthering myself in this field and I am hoping this certificate will help with that. Overall, technical issues aside, these courses were a great learning experience and I recommend them for anyone wanting to learn IT.

I learned a lot from this course. Taking this course made me realize that it is not enough to take a course one time. Over time, changes in IT happens so rapidly and it is very essential to be aware and updated of the latest trends and innovations being offered in the market so you are in great shape in terms of skills, knowledge and expertise. Learning should be a continuous process and we must never stop from learning new things. It is to our advantage if we develop this habit of continuous reading, researching, attending training and the good part is, everything is now online an so convenient and we must take advantage of this offering.

I would recommend this course to those who really interested in Cyber Security but have no previous knowledge about this area. This course including almost all relevant topics about this area. Basically, it's a introduction of those potential threats and how to defence those attacks. For new students, I would advice you to take notes when you watch the videos. The final assignment is really critical and need understand those key concepts. I have tried several times to pass this unit. Thanks to the peer reviewer, they're really serious but indeed help me to improve. 5 Star course. Thanks Google and Coursera.

It was really interesting and good course. Cyber security is now a must for any person or company or country, hospitals or military services in the world. Before this course i was not aware of so many encryption, decryption methods and security protocols and features. I have learned a lot about security and privacy and importance of installing them into any kind of IT infrastructure and services.

The teacher really excellent , handsome and smart while delivering the lectures.

I believe I have received essential quality lectures, teaching contents from an excellent teacher and an excellent subject.

The tutors of this and past courses were very concise, clear, and engaging. Anyway this course was great given how they broke down some complicated concepts about security through visuals and great monologue. It even showed that most breaches can be prevented with simple practices or policies. There was some great context to show how the subject can be applied to real world scenarios. My only complaint was given how technical and complicated some of the subjects are especially week 4. Although, I can't say anything too bad about it, only so much you can simplify.

Thank you for this course which was very interesting. It was very complete so there is a lot to understand and remember. The instructor explains very well and as my mother-tongue is not English, I understood him very well (thank you for the subtitles!). I am very happy that I've finished this IT Course and I would recommend it!

The only thing I am wondering is: what is done with my written answer? I've written texts for some quizzes and I was wondering if someone was reading them. It is just a curiosity!
