I loved the exploration of topics as well as the depth it took with each concept. I feel like I have learned a whole lot from this course regarding networks, their protocols, ways to secure them, and more. I definitely recommend this as someone with little background in networks.

Great course and the CISO that did the bulk of the presentations had a great presentation and was easy to follow and understand the concepts he was explaining. I also love the real-life people who are talking about their experiences and practical usage of the skills taught.

Great content with plenty of new information to learn. I believe the content of this course is fundamental to any aspiring cybersecurity student. I thank Google and Coursera for this high quality education. And may I add that the instructor's moustache is just magnificent.

case-based learning provides a powerful way to teach network fundamentals as it bridges the gap between theory and practice. I not only equipped with knowledge but also gain the confidence and competence to apply that knowledge in real-world networking situations.

I have studied computer networks from an academic point of view.

This is one of the most intensive courses I've ever had before.

Don't feel overwhelmed by the dense information packed in this course. Some of the material will be clear once you start practicing it.

The instructor was very good at explaining the material, his speech speed was just right. His knowledge was excellent and he was able to transfer his knowledge in a way that not too many instructors could have done like he did. Thank you for a great course!

I greatly enjoyed this course and its breath of topics. Again, very well presented. Engaging, interesting, no fluff! Plus, the short "how I got into Security" videos of Googlers from different departments are great, motivating and interesting! Thanks :-)

This course was incredibly informative for me, as it allowed me to deepen my understanding of many concepts, I had encountered in other cybersecurity courses but hadn’t fully grasped until now. Kudos to the instructor for doing an excellent job!

Lovely program. I hope that Google and Coursera keep this course up to date. Right now, the course is timely and very accurate information-wise. I hope the course is continually worked on and some free writing projects adjusted over time.

Muy complacido con todos los conocimientos que he adquirido en este curso, un paso mas en mi aprendizaje, un paso mas para mejorar mis habilidades en ciber seguridad. Lo recomiendo a quienes quieran mejorar sus habilidades y conocimientos.

The challenge of this course compared to the first two was great! I found myself with questions that were more advanced than the provided information. The Coursera AI Coach helped me stay focused on the pertinent information though.

This is a very interesting course about network security. I liked the introductory part with the TCP/IP four layer model in comparison to the OSI seven layer model. I am looking forward to completing more courses from Google!

A lot of material and it has more exercises than the previous section. But the instructions are clear and the concepts are explained well. The exemplars are very helpful. I feel like I learned a lot at the end of this course.

The course was well structured and well presented making my learning experience thoroughly enjoyable and effortless. More importantly, the constant encouragement ( "You're doing great.") by the presenter made me persevere.

Very clear content that was delivered at a good pace. I was familiar with some concepts but the course still helped me consolidate my understanding and see links between infrastructure and where it is relevant for security

The Networks and Network security course was very interesting, and I paid keen attention to many details because as a beginner, I am still considering a specialization. This course claimed my attention. I loved it.

The only thing I would improve upon is how you introduce writing incident reports. I would introduce the instruction document that you end up giving in the 1st exemplar as part of the reading before the exercise.

Fantastic start for Understanding how Network functions and to protect them. A womderful introductory course on Network Security. Must do for begineers and a good referesher for already aware professionals.

This course was great, the way they explain the network architecture in general and the way they summarize it in such a simple way shows that it was done by a professional with vast experience in the field.

This Network Security Course is just amazing. For People who wants change carrier I will deeply recommended. Is so well explain all information, by professional people. I personally love it this course.

Really learned a lot, got a good understanding of networks basics. There is a lot to capture through the links and resources given along with the course. Really excited to take this journey with Google!!

The combination of video, illustration, reading notes and hands-on practice was very effective in getting me to get a solid knowledge of the topics, and gave me confidence in doing the tests and quizzes.

Excellent course, I consider that the information presented is of very good quality, I have learned valuable concepts for a cybersecurity analyst and I hope to finish the certification with good results.

C'est un cours que j'ai particulièrement apprécié. Chris est très technique et il y a beaucoup de choses a retenir. Mon expérience en tant qu'amateur m'a beaucoup aidé dans les études de cas.

This course really surprised me, it was in-depth on the subject, thank you to everyone involved, very good, incredible, I am very happy with the immense knowledge I acquired in this course.
