What do you like best about CyberDefenders?
I’m speaking from the perspective of someone who studied Systems Administration, completed a Cybersecurity specialization course, has one year of experience in IT support, and has passed both the BTL1 (100/100) and CCD (80/100) certifications.
Compared to BTL1, the difference in level is immediately noticeable: everything feels more complete, it includes many genuinely useful tools, and it’s clearly an intermediate-level certification. It assumes you already have a certain base of knowledge and doesn’t treat you like a beginner.
The lab quality pleasantly surprised me. They’re well designed, realistic, and aligned with what you’re expected to do. The fact that there’s one investigation lab that’s significantly more challenging than the rest, with no write-ups or help, and that it rewards you with 5% of the exam grade, is honestly one of the best ideas I’ve seen in a certification.
There is one point that may seem negative at first (and I didn’t include it in the main review because I actually see it as a positive), which is the restriction on copy and paste. I am not a native English speaker, but I can speak, write, and read it. Even so, watching the lessons in English and having to translate and summarize them mentally is more demanding.
However, in the long run, it is much better. It forces you to write everything manually without relying on ChatGPT or translators where you can simply copy and paste and be done with it.
As for the exam itself, it’s comprehensive, demanding, and long, but also very rewarding. When you finish, you feel that you didn’t just take an exam—you actually learned something and came away with noticeably more knowledge than before.
I’d recommend this certification to anyone with basic IT knowledge and some Blue Team fundamentals. That said, you can also take it without a strong cybersecurity background, because everything is explained very clearly.
Beyond the technical content, I also want to mention a few things about the platform and overall experience. These may not be directly related to cybersecurity skills, but they really make the course easier to enjoy and get the most out of:
1. The platform is really easy to navigate and well organized. Everything—the lessons, labs, and resources—is laid out in a logical way, which makes it simple to follow and keeps the learning experience smooth.
2. Getting started with the labs is straightforward. The instructions are clear, and the environment is ready to use right away, so you can focus on learning instead of dealing with technical setup issues.
3. Customer support is responsive and very helpful. Whenever I had a question or ran into a problem, I got clear guidance in a reasonable amount of time. My lab time ran out, and they were kind enough to give me a few more days of access (I had already passed the exam at that point).
I used the platform pretty much every day while going through the course, especially for labs and practice exercises. The hands-on content keeps you engaged and makes it easy to actually apply what you’re learning. Review collected by and hosted on G2.com.
What do you dislike about CyberDefenders?
There are a few things I didn’t like as much. For instance, once you finish the exam, you can’t see where you went wrong. I understand the reasoning to a point, since it helps prevent answers from being shared with other students, but it still left me wondering what I missed.
At times, some of the videos don’t add much to the explanation and feel more like a voiceover repeating theory you’ve already studied.
I also would have liked to see a Linux module. Even as optional material, it would have been a great addition. That said, considering everything the course already offers, it isn’t essential—just something extra that would have been nice to have. Overall, these are minor complaints and haven’t been a serious issue for me, but I thought they were worth mentioning.
As a suggestion rather than a complaint, it would be helpful to be able to reset lab answers, even if only once. This option exists if you fail a lab, but it isn’t available beforehand. Review collected by and hosted on G2.com.
