I felt very intimidated at first learning these security concepts, but what I find rewarding is the fact that I have just become familiar with them now. Don't let anything intimidate you in learning from this course as you will get the hang of it later on when you find an IT job. It has deepened my knowledge in IT and I feel it definitely will prepare me for the CompTIA A+ exam.

The Google IT Support Specialization course is one big and straight question: Do you wish to work in the IT Support industry?. The answer to the questions, regardless of it, is going through this course. The users will have a clear answer and will be wiser in such way they can make a better decision on their next carrier step. Very well done Google.

First of all, coolest title ever. Now to the content of the course, it was everything I hoped for. If there was anything I wanted to know that wasn't discussed, there was a link included, to access the information. And just like i said about the other courses in the program, this was wholesome and I thank Coursera and Google for making it possible.

I greatly enjoyed this course. I was a great intro in to the Security sector of IT and gave me a great foundation to move into my new career. The pacing and the information and well as the presenter were all fantastic. I especially enjoy the hands on labs, which gave me some much needed experience with the command line command use.

The course is very good at giving a good summary of the security roles a System Admin may encounter. It helps to point the student in the right direction for more detailed instructions in each area. I enjoyed the course. It contained the correct amount of material. I am confident in continue my search on how to secure networks.

by Adegoke M O


I've never completed a course like this before (remote instruction) and I cannot express how great the instructor was and the overall content of the material. I would definitely recommend this to my co-workers as well as friends. I will be looking into taking more of these classes through COURSERA in the near future.

Thank you!"

I knew IT security is a complex matter. Nevertheless, it came as a surprise to me how comprehensive this course was. Malware, Cryptography, Firewalls, Policies etc. I would like to thank our instructor for his well-taught course. I have learned a lot. I am afraid, however, I can't keep all details in my long-term-memory.

by Susie H


This was an informative, interesting, and one of the more important modules. Some of the videos had a lot of details which could potentially lose the attention of the viewer, but Gian led us through it in a clear and concise manner. When he would interject his humor, it came across as natural and genuine, and not forced.

It is vital to know how to protect our IT infrastructures from the digital dark arts. This course gives a valuable and overall introduction to preparing us to understand the many ways our systems and networks are exposed and how we can mitigate and prevent those risks using sound protocols, technologies, and behaviors.

IT Security: Defense against the digital dark arts is a very good course since it equips one with the practical challenges that one may encounter in their IT support specialist role. I particularly have gained a lot from this course. I am very grateful to Google in conjunction with Coursera for offering this course.

Gracias a este curso, he conseguido nuevas herramientas y abilidades que antes no tenía y he afianzado las que ya tenia. Me ha hecho más conciente sobre la prevención en Internet, pero, a la vez, muy desconfiada, especialmente sobre descargar apps de otra organización. (Sólo descargo apps que pertenezcan a Google).

A Big thanks to all instructors for what I've learned all those months and will continue this learning journey, because that is what makes successful as a whole. As the Greek philosopher Solon said: "Γηράσκω δ' αεί πολλά διδασκόμενος", which in a way means, even though I'm getting older, I am always learning a lot

by Nishant K G


When I started this course I just had a basic knowledge about Computers, but after completing this course I feel like I know about IT Security now, obviously, there's a lot to learn about Computers, its a very vast field, but this course helped me build my foundations on IT Security.

Thanks, Coursera and Google!

It was an excellent course! I definitely learned a lot from it. My perspective regarding security has changed a great deal from it. Even if you don't take this course for the certification, I would definitely recommend it for learning how to protect yourself and your devices on the internet and from attackers.

by Alejandro M


Everything has been interesting, what I have struggled with the most has been with the translations and the amount of acronyms, my next steps are to expose it to my employment counselor and together plan my spasos to follow, I think it will be to continue training, I would like to learn the Web development
