Awesome. Just awesome!!! I have learned so much, and IT Security is just up my alley with all of my previous security experience. Now I will take those skills into the digital realm.

It was in depth concept and was very useful. I finally gained a basic knowledge of IT Security.

Many Thanks to the Instructor for providing a valuable knowledge about the the course.

Excellent course. Some of the material here will be to complicated for many beginners. If you're one of those, please take your time and ask questions to include Zendesk support.

I am glad I took this course and have learned so much. I totally recommend. Now I am just waiting for the next step to find a job in a great workplace where I can apply my skills.

An excellent comprehensive exploration into defending network topologies and the aspects of infrastructure that provide connectivity, transactional, and communication convenience.

Great learning experience! Its explained and planned very professionally, with lot of humor in between , highly recommended for learners who want to explore career in IT security.

Overall this course was very challenging and helpful, because I've learned a lot about the IT security world. Big Thank you to all the instructors who made this course a success.

Appreciate the way some of the very complex concepts have been simplified . It covers the complete array of topics. And finally the hands on qwiklab exercies have been helpful.

I love the broad perspective of IT that this course has given me; I know that the rest is left to me and that it is only the beginning of a wonderful journey!

Thank you, Google!

muy bueno el curso enseña cosas muy importantes sobre la seguridad dentro de las redes que para hoy en dia es muy importante ya que las telecomunicaciones estan en todo lado

I thought i knew how to keep my computer secure , but after this course i realized the moment i open my browser , i am under attack i should not just click on anything i see

This course was very important because I understood a lot about IT Security! And of course I need to learn much more! Thanks to all Coursera and Goggle Team of instructors!

This is one of the most interesting training of this course, it brings the computer world to a new level. Hope we can work on this and help to protect users and ourselves.

This course is vital as it can even teach some of the basic security systems that you can even apply to you own devices in the real world to protect yourself from hackers.

Really a fantastic course! I especially enjoyed the parts on encryption and cryptography in general, and I feel like I really have a good grounding in IT security now.

excellent course but the hands-on labs are buggies and even if I did it correctly still failed or got 50% and had to do it several times before it recorded accurately.

Encryption concepts were explained beautifully. As a developer with 20 years experience I got to understand things better than I understood before I took this course.

Expectation met and i'm looking forward to diving into more Google facilitated programs. I will also suggest that google gets more involved in more Coursera programs.

the last assignment was hard, but managed to pass it, thank you google and all the instructors for your hard work to make this course useful and easy to understand.

This course was great, good material and presentation by the instructor. Learned a lot about security and now I am interested in doing in-depth courses in security.

A very good refreshment in my knowledge about security and protection, also to know how to implement good habits among employees to keep a safe working environment

Really great. The course filled in many blank spots in my knowledge and experience. It gave me new perspectives both on tech support and dealing with IT threats.

Great course! I really think Google and Coursera are a great partnership and I highly recommend this course for those starting out on their Cyber Security journey!

Great Experience.!

Must enroll yourself, if you really interested and want to learn and explore new things and want to dive deeper in the field of Network Security.

it's was really help full for me and my further future I learn A lot of things from this course about security and implemention more on. Thanks all Coursera Team.
