I recently passed the SecX exam, and my biggest takeaway is that it felt much more practical than I expected.
Going in, I studied with about 200 pages from a prep book and some Dion practice exams. That helped, but the real surprise was how much the exam seemed to test judgment rather than memorization.
Security+ often felt like a vocabulary exam to me. SecX did not. The questions were more situational and often gave several answers that all seemed at least somewhat reasonable. In many cases, the challenge was reading carefully, understanding what the question was really asking, and eliminating the options that were merely acceptable instead of the best fit.
What stood out most was the breadth of the exam. It covered a wide range of topics, and I was especially surprised to see a Linux VM as part of the experience. That immediately made the exam feel more grounded in real work instead of pure multiple choice theory.
Looking back, some of the most helpful context I had did not come from traditional exam prep alone. My Linux+ studies helped. So did the hands on work involved in configuring my site and dealing with practical DNS and email related concepts like DKIM, DMARC, and SPF. That kind of background gave me a better frame of reference for some of the questions than memorizing definitions ever could.
That was probably the most interesting part of the exam. It felt like it was pulling from different parts of my experience at once. Instead of asking whether I knew a term, it often felt like it was asking what I would actually do in a security situation.
I also think that is what made it challenging. The exam was not just about knowing content. It was about applying it under pressure, dealing with vague answer choices, and staying disciplined enough to reread questions instead of rushing.
Overall, I thought it was a solid exam. Difficult, broad, and more practical than I expected.
I do not have some huge list of breakthrough study advice for it, but I do think this is one of those exams where real technical context matters. Time spent working with Linux, infrastructure, and security fundamentals felt more valuable than trying to brute force everything through flashcard style memorization.
For anyone considering it, that would be my honest takeaway: expect breadth, expect ambiguity, and expect to think through the questions carefully.
