Great courses It gives me knowledge and experience on how to protect myself and company that I will work for on the danger and implement a solution. Even though it was a beginners course it's give a very strong foundation. This course is great for novice and profesional who never expose on IT security.

This course is a very good one. My only concern is that it is less practical. We need some practical experience. If you cna include at least one software to exercise this new tool, it will be great. Too many new terms are digested here without any practical take away. Please take in consideration this.

Very captivating and I loved the labs because it allowed me to get hands on experience with both Windows and Linux systems. This is the perfect starter course for someone interested in getting into IT Support. I highly recommend this course to everyone who asks me how to get started in the IT field.

Of all of the five courses in the IT Support Specialist specialization, I found this one to be the easiest to grasp. That might be because by now we've learned a lot of different information in the first four courses. I definitely just had an easier time grasping new information in this course.

My favorite course in the series. The other day, I was made aware of a major security breach in a top 10 social media news source. I UNDERSTOOD EVERYTHING IN THEIR POST-MORTEM! In my opinion, this was the course that really pushed me for the first time in the series. Give me more Google!

This course provides some serious and technical insights on IT security. With good number of assignments and quizzes, you will be able to relate security practices that are being used in your current firm as well as use them when you get a chance to become sysadmin for an organization.

Wow was this comprehensive! Just basic information of course, but so many things! Recommend for people who want a basic overview of how IT security works. Managers and non-tech people will benefit by learning where their organization is lacking in security and how it can be improved :)

Course 5 was very informative and gave me a new perspective on computer, networking, and online security. Nothing is 100% secure. But with the right methods and backups in place, you can minimize the impact of an attack and increase your security with a defense-in-depth mentality.

Although I've already taken and passed the CompTia Security + exam this was an amazing course, it's a great refresher for those looking to recap on previous knowledge or anyone looking to get their feet wet. I'm looking forward to more courses by Grow with Google in the future.

Excellent course to develop a breadth of knowledge. I had some basic coding experience coming in, and this course definitely opened up some interesting paths to explore. I feel comfortable after going through the material a couple of times, to take on an entry level IT role.

A lot of useful and valuable information packed in each week. If you take your time and re-read the supplemental material, you should not have any issues. I was surprised at the new information that was available. Also, I appreciate the words of encouragement in the videos.

In pursuing certification this part for me was the most challenging. Once completed I realize this is the best part. Not a week goes by in the news without mentioning ransomware, data breaches, et al. Data security should be protected from bad actors now more than ever.

IT Security was one of the best courses I enjoyed learning. I'm still in the infancy level though. I need an entry-level training in this particular field. I thank Coursera and Google who helped me to achieve this certificate. The quizzes and lab were very knowledgeable.

I absolutely loved this course. The background of malicious processes that were then paired with specific security protocols and best practices was very well rounded and useful going forward. The final project was both overwhelming and absolutely rewarding in the end.

This course was tough but it taught the basics of securing networks and hosts very thoroughly. I've taken this course in conjunction with a course to prepare for the CompTIA A+ exams. It is a great extension and complement to that exam. I would highly recommend it!

For anyone starting out like myself, the security information in this course was a great introduction. You really understand the security concepts, best practices, tools, and it even covers user habits and creating a security culture. I'm glad I took this course.

I've been in IT for a few years and since I was a kid I just enjoyed tinkering with computers. One of the most interesting parts of this course was the Cybersecurity section, I couldn't have imagined how many tools and resources there are out there. Great course!!
