- SecurityX (exam code CAS-005) is CompTIA's expert-level cybersecurity credential, delivered via Pearson VUE.
- The exam has up to 90 questions, a 165-minute limit, and pass/fail scoring with no scaled score.
- Security Engineering is the largest domain at 31% of exam content.
- CompTIA recommends 10 years of IT experience, including 5 years of hands-on security experience.
What SecurityX Actually Is
SecurityX is the Computing Technology Industry Association's (CompTIA) expert-level cybersecurity certification, positioned above its associate and intermediate security credentials. It replaced CompTIA's former advanced security practitioner track and is now tested under exam code CAS-005, aligned to Version 3.0 objectives. Unlike entry-level certifications that test foundational knowledge, SecurityX is built for practitioners who design, engineer, and operate enterprise security programs rather than simply configure individual tools.

Exam Format and Registration Mechanics
SecurityX is administered through Pearson VUE, either at a testing center or via online proctoring, giving candidates flexibility in how and where they sit for the exam. The format itself is deliberately mixed:
- Up to 90 questions combining multiple-choice items with performance-based questions (PBQs) that simulate real security tasks.
- 165-minute time limit - a substantial window, but performance-based questions can consume disproportionate time if you haven't practiced the interface.
- Pass/fail scoring only - there is no scaled score reported, so you won't know how close you were to a specific numeric threshold.
This scoring model changes how you should prepare. Because there's no partial-credit narrative to chase, your goal is consistent competence across all four domains rather than over-optimizing one area.

Key Takeaway
Because SecurityX uses pass/fail scoring with no scaled feedback, treat every domain as equally "must-pass" rather than banking on strength in one area to offset weakness in another.
The Four SecurityX Domains
CAS-005 organizes its content into four weighted domains that map to the full lifecycle of enterprise security work - from setting policy down to hands-on engineering and daily operations. Understanding the weighting is essential to allocating study time correctly.
| Domain | Weight | Focus Area |
|---|---|---|
| Governance, Risk, and Compliance | 20% | Policy, risk management, regulatory alignment |
| Security Architecture | 27% | Designing resilient, secure enterprise systems |
| Security Engineering | 31% | Implementing controls, cryptography, secure design |
| Security Operations | 22% | Threat detection, incident response, monitoring |
Domain 1: Governance, Risk, and Compliance (20%)
Candidates must translate business objectives into security governance structures, evaluate third-party and supply chain risk, and align controls with regulatory frameworks.
- Risk assessment methodologies and risk treatment decisions
- Policy, procedure, and compliance mapping across jurisdictions
A full breakdown lives in SecurityX Domain 1: Governance, Risk, and Compliance (20%) - Complete Study Guide 2026.
Domain 2: Security Architecture (27%)
This domain tests the ability to design secure network, cloud, and hybrid infrastructures that hold up under real-world attack conditions and business constraints.
- Zero trust and segmentation design decisions
- Secure cloud, virtualization, and infrastructure patterns
See SecurityX Domain 2: Security Architecture (27%) - Complete Study Guide 2026 for the detailed objectives.
Domain 3: Security Engineering (31%)
As the largest domain, Security Engineering carries the heaviest weight on exam day and covers the applied, hands-on side of building secure systems.
- Cryptographic implementation and key management
- Secure software, identity, and endpoint engineering practices
Because this domain dominates the exam, the dedicated guide at SecurityX Domain 3: Security Engineering (31%) - Complete Study Guide 2026 deserves early attention in your plan.
Domain 4: Security Operations (22%)
This domain evaluates how candidates detect, analyze, and respond to active threats within an operational environment.
- Threat hunting, incident response, and forensics workflows
- Security monitoring tooling and automation
Review SecurityX Domain 4: Security Operations (22%) - Complete Study Guide 2026 for scenario-based practice topics.

Who Hires SecurityX-Certified Professionals
Because SecurityX targets architecture, engineering, and governance work simultaneously, it maps onto senior and lead-level roles rather than entry positions. Organizations typically look for this credential when filling roles such as:
- Security architects responsible for enterprise design decisions
- Senior security engineers building or hardening infrastructure
- Risk and compliance leads bridging technical and governance functions
- Security operations leads overseeing detection and response programs

Experience Requirements and Who Should Attempt It
CompTIA doesn't enforce a hard prerequisite gate for SecurityX, but it does publish a strong experience recommendation: at least 10 years of hands-on IT experience, including at least 5 years of broad hands-on IT security experience. This isn't a formality - the exam's performance-based questions assume you've already worked through architecture trade-offs, incident response scenarios, and governance decisions in a real environment.
If you want data-informed expectations before scheduling, SecurityX Pass Rate 2026: What the Data Shows discusses what's publicly known about outcomes without inventing numbers CompTIA hasn't released.
Certification Validity and Renewal
Once earned, SecurityX is valid for three years. To keep it active, certification holders renew through CompTIA's Continuing Education (CE) program by earning 75 CEUs within that window - typically through a mix of relevant training, higher-level certifications, industry activities, and academic credit, depending on CompTIA's current CE program rules.
This renewal structure matters when weighing SecurityX against other credentials: it's not a one-and-done exam, so factor ongoing CE effort into your long-term certification planning, not just the initial study period.
How to Sequence Your Preparation
Given the domain weighting, a sensible study sequence starts with the heaviest domain first while your energy and time are highest, then moves toward lighter-weighted areas.
Security Engineering (31%)
- Cryptographic protocols and key management scenarios
- Secure system and application design patterns
Security Architecture (27%)
- Zero trust models and network segmentation design
- Cloud and hybrid infrastructure security trade-offs
Security Operations (22%)
- Incident response and threat hunting workflows
- Monitoring, detection, and automation tooling
Governance, Risk, and Compliance (20%)
- Risk assessment and treatment methodologies
- Regulatory and third-party risk mapping
Integrated Review
- Full-length practice exams under the 165-minute limit
- Performance-based question drills across all four domains
This isn't a generic template - it's ordered specifically by CAS-005's weighting so you front-load the highest-scoring domain instead of splitting time evenly. For a fully detailed week-by-week plan with resource recommendations, see SecurityX Study Guide 2026: How to Pass on Your First Attempt. You can also validate your readiness against realistic exam conditions using the practice exams on SecurityX Exam Prep before scheduling your Pearson VUE session.
Key Takeaway
Study Security Engineering first since it carries the most exam weight at 31%, then work backward through Architecture, Operations, and Governance.
