Nice refresher on the core concepts. I already knew most of the networking side but the way it framed threat basics and data protection was a good reminder of why we do what we do.
Great intro to zero-trust.
Exactly what I needed to brush up.
I've worked in IT support for six years and always dealt with security stuff second-hand without really understanding the why behind it. This course filled in a lot of those gaps for me. The way it walks through common threats, then moves into how zero-trust and network defense actually address them, made everything connect. I feel a lot more confident in conversations with our security team now, and I've already started applying the mindset to how I set up user access at work.
Very clear, thanks.
Solid foundations course. Covers zero-trust and network security clearly, though I'd have loved a deeper dive into real-world incident examples.
What I appreciated most was how it built the reasoning behind each control rather than just listing them. You come away understanding why least privilege matters, why you verify every request, and how those ideas protect sensitive systems. That kind of conceptual grounding sticks with you far longer than memorizing definitions. Highly recommend for anyone new to the field who wants to actually understand security instead of just passing a quiz.
The section on securing networks and thinking about threats was practical and easy to digest. I finished it over a weekend and already changed how I approach access on our internal tools.
Really useful foundations, though I wish there were more hands-on labs to practice securing an actual network instead of just learning the theory. Still, the explanations of the concepts are strong and easy to follow.
Clear and well paced.
Good coverage of network security basics. I would have liked a bit more depth on firewalls and segmentation, but for a foundations course it does the job well.
Solid fundamentals.
I'm switching careers from marketing into tech and was honestly nervous this would go over my head. It didn't at all. Everything is broken down into plain language, and by the end I understood how networks get attacked, why data protection matters, and what zero-trust is actually trying to solve. It gave me the vocabulary and the confidence to start applying for junior security roles. Genuinely one of the better decisions I made this year for my career change.
Good overview of protecting data and systems, easy to follow even after a long day at work.
Really approachable for a beginner. The threat basics and security mindset parts stuck with me the most.
Explains the security mindset really well without drowning you in jargon.
As someone brushing up before a certification, this hit the right level. It doesn't pretend to be advanced, it just gives you a clean, honest foundation in the core ideas, threats, network defense, data protection, and the zero-trust model. The pacing is steady and nothing felt rushed or padded out. I'd point any beginner on my team to this before they touch anything more technical.
I came in knowing basically nothing about security and left actually understanding how to think about protecting data and systems. Good starting point.
