CompTIA SecurityX training FAQs

Should I have other cybersecurity certifications before taking SecurityX training?

Yes, having other certifications and experience is highly recommended. Because SecurityX focuses on designing, governing, and assessing security at an organizational level, it’s best taken after you’ve built a solid technical foundation. Certifications like Security+, PenTest+ and CySA+ from CompTIA help lay the groundwork for this SecurityX course.

How much does the SecurityX cost?

The SecurityX (CAS-005) exam costs $529 for a single attempt. For $578, you can purchase a retake option in case you don’t pass the first time. Because the exam is broad and challenging, a focused course like this helps you prepare efficiently and avoid the need for a costly retake.

Is the SecurityX exam (CAS-005 v5) difficult?

Yes. The SecurityX exam is challenging because it covers advanced cybersecurity topics across governance, architecture, engineering, and operations. Questions focus on judgment, tradeoffs, and design decisions rather than memorization. This course helps you understand how those concepts connect, making the material easier to reason through on exam day.

Is SecurityX good for beginners or junior cybersecurity professionals?

No. SecurityX is designed for experienced cybersecurity professionals. The exam assumes deep familiarity with security concepts, enterprise environments, and real-world technical skills. If you’re early in your cybersecurity career, this course will probably feel overwhelming, but it’s an excellent goal to work toward as you gain experience.

Is the SecurityX certification worth it?

Yes. SecurityX signals that you can think beyond tools and tactics and lead security strategy at an organizational level. It’s especially valuable for roles involving compliance, architecture, and decision-making. It’s also good for government work where DoD 8140/8570-approved certifications carry real weight.

Who is CompTIA SecurityX training for?

This CompTIA SecurityX course is for senior cybersecurity professionals, security architects, and technical leaders who make security decisions at scale. Since it’s DoD 8140/8570-approved, it’s also especially valuable for government employees and contractors.

What our learners say

When learning a new technology, people sometimes build a wall that complicates the learning process because of the unknown. I like tearing down that wall — and having people fall in love with that technology.

Practice exams help you have an overview of your readiness. If you have failed a couple questions in one area, you can go back and work on them.
