Course Description

The CompTIA SecurityX CAS-005 certification course prepares candidates to architect, implement, and manage secure solutions across complex enterprise environments. This advanced certification validates expertise in cloud, on-premises, and hybrid environments, along with cutting-edge knowledge of cryptographic technologies and emerging trends like artificial intelligence. The course emphasizes critical thinking, governance, compliance, and the application of security practices for a resilient enterprise framework.

Full-Length Practice Exams

The course is designed to thoroughly prepare candidates with six comprehensive practice exams. Each exam simulates the real-world test environment to help students build confidence and expertise. These practice exams are carefully crafted to mirror the structure and complexity of the actual certification exam.

Exam Format and Duration

Each practice exam contains a maximum of 90 questions, blending multiple-choice and performance-based formats. The duration for each exam is 165 minutes, offering ample time to assess and refine your knowledge and skills under real-world constraints.

Scoring and Feedback

Upon completing each practice exam, candidates receive detailed feedback, including domain-specific performance metrics. This ensures an understanding of strengths and highlights areas requiring further study. The feedback system supports tailored learning, focusing on improving performance in governance, architecture, engineering, and operational security.

Exam Domains and Their Weightage

The CompTIA SecurityX CAS-005 exam focuses on four key domains, each contributing to the overall exam content. This course provides comprehensive coverage of these domains, ensuring mastery of critical concepts and practical applications:

Governance, Risk, and Compliance – 20%
Covers the implementation of governance frameworks and security programs, focusing on policies, procedures, risk assessments, and compliance requirements. This domain emphasizes threat modeling and risk management strategies to ensure alignment with enterprise security objectives.

Security Architecture – 27%
Focuses on designing secure and resilient systems, incorporating advanced controls such as Zero Trust, hybrid infrastructures, and cloud environments. This domain ensures a deep understanding of secure practices throughout the system life cycle, including software assurance and secure access design.

Security Engineering – 31%
Addresses the enhancement of security measures for endpoints, networks, and systems, including troubleshooting identity management and securing specialized hardware. Automation tools and techniques for patching, monitoring, and orchestration are key elements of this domain.

Security Operations – 22%
Equips candidates with the ability to monitor, analyze, and respond to security incidents using SIEM, behavioral analytics, and threat intelligence. This domain also covers incident response activities, such as malware analysis, root cause analysis, and data recovery, along with effective reporting and visualization.



What Other Students Are Saying About Our Courses:

  • Everything was well explained and informative. Was nice that it included some of the more important material to help review instead of just leaving the previous certification information as all "assumed knowledge" and passing the buck. As always, these courses continue to be the best training I have used so far. (Jonathan B., 5 stars)

  • I have been in the industry for between 5 and 10 years, and needed a refresher on several of these topics before taking the exam. Course is designed well, so you can focus on those areas that you need to, while listening to the others in the background as a refresher for the others. (Jamie R., 5 stars)

  • I would recommend it to anyone aspiring to complete your examinations at the end, I completed the course and successfully passed my exams on the first attempt (Bankole K., 5 stars)


Upon completion of this course, you will earn 17 CEUs towards the renewal of your CompTIA Tech+, A+, Network+, Security+, Linux+, Cloud+, PenTest+, CySA+, or CASP+ certifications.

There are some egregiously bad reasoning to the answers of some questions. Some of the questions themselves are just weirdly phrased. Some material is also not covered by the accompanying video course; probably because of the move from CASP to SecX. I appreciate the amount of content though. I think it covers all you would need for the exam, I just wish it was executed better.

So far so good! Please keep up the good work that you do! Sincerely, Perry Shelton

By Liam Etcheto on 2/11/2026

I feel like some of the explanations to the questions should be more thorough. There's a fair amount of questions that have answers I disagree with at face value and later understand, or just outright disagree with, and it would be extremely helpful to have a more thorough explanation on those vague questions that have multiple lines of reasoning for the answers.

By Dylan Larrabee on 1/23/2026

Some questions appear to not make sense grammatically. I am not sure though. Otherwise these questions are way harder compared to Comptia's practice tests which is probably a good thing

By Andrew Brumley on 11/17/2025

While these tests did not match up as closely to the actual test as I thought they would, they were a huge help in identifying areas where I needed to study exam topics on my own more closely. Overall, I think this is a great study tool and is a must-have expansion if you are buying the lectures.

By John Brown on 8/26/2025

Passed my SecurityX on the first try. These tests gave me the knowledge I need to understand the question types.

By Nour AROUSSI on 8/26/2025

the Material was good and the explanation help understand the Material better. i just wish there was more real life Simulations and PBQ like we see in the exams

By Wudison Gomez on 7/5/2025

I passed on the first try!! This was excellent material, and I feel like it prepared me for the types of questions that would be on the exam. Please keep it going, and know that it is an awesome way for students or any cyber professional to use to study.

By Christopher Luddy on 6/17/2025

Just passed exam, you got the best practice exam questions! CompTIA CASP+ / Security X certified as of yesterday! Thank you!

By Chris Russo on 5/16/2025

Just passed this exam. These questions definitely helped. They are similar in concept and level of difficulty. Combine this with practical hands-on experience and you’ll be fine.
