CompTIA SecurityX (CAS-005), launched on December 17, 2024, is the successor to CompTIA CASP+ (CAS-004) and represents the capstone certification in the CompTIA Cybersecurity Career Pathway. It validates advanced technical skills required to conceptualize, engineer, integrate, and implement secure solutions across complex enterprise environments — encompassing security architecture, engineering, operations, and governance, risk, and compliance. The certification is vendor-neutral, ANSI-accredited to ISO 17024 standards, and approved under DoD 8140/8570 as a baseline for IAT Level III, IAM Level II, and IASAE Levels I and II.
Unlike many cybersecurity certifications that focus on managing security programs, SecurityX emphasizes hands-on technical depth. Candidates must demonstrate proficiency in designing hybrid and multi-cloud secure architectures, applying advanced cryptographic technologies, automating security operations, and leading incident response across enterprise-scale environments. The exam also addresses the security implications of emerging technologies such as artificial intelligence, containerization, and CI/CD pipelines.
SecurityX is designed for senior security engineers and security architects who are responsible for designing, implementing, and managing security solutions rather than simply administering them. Ideal candidates typically hold roles such as Security Architect, Senior Security Engineer, Security Operations Lead, Security Integration Engineer, or Systems Requirements Planner.
The certification is also aligned with multiple NICE Cybersecurity Workforce Framework work roles and DoD 8140 positions, making it particularly relevant for professionals in government, defense contracting, and federal agency environments. Candidates should have substantial hands-on experience and be operating at a level where they are making architectural decisions and leading security initiatives, not just executing them.
CompTIA does not enforce formal prerequisites for CAS-005, but recommends a minimum of 10 years of general hands-on IT experience, including at least 5 years of hands-on technical security experience. Candidates are expected to possess knowledge equivalent to CompTIA Network+, Security+, CySA+, Cloud+, and PenTest+ — either through those certifications or equivalent professional experience.
In practice, candidates who attempt SecurityX without a strong foundation in network security, cryptography, cloud infrastructure, and security operations often find the exam extremely challenging. Professionals who have already earned Security+ and CySA+ (or CISSP/equivalent) and are working in senior technical security roles are the most common and well-prepared candidates.
The CAS-005 exam consists of a maximum of 90 questions, delivered in a maximum of 165 minutes. Question types include both multiple-choice and performance-based questions (PBQs), where candidates must interact with simulated environments or scenarios to demonstrate applied skills. The exam is available in English via online proctoring through Pearson VUE's OnVUE platform or at a physical Pearson VUE testing center.
The exam uses a pass/fail grading model — no scaled score is reported. CompTIA does not publish a numeric passing threshold for SecurityX; candidates simply receive a pass or fail result. The certification is valid for three years and can be renewed through CompTIA's Continuing Education (CE) program by earning 75 CEUs within the three-year cycle.
SecurityX holders command some of the highest salaries in the CompTIA certification portfolio. The average reported salary for SecurityX practitioners is approximately $165,000, with security architects and senior security engineers typically earning between $155,000 and $200,000+ depending on sector and geography. The certification's DoD 8140/8570 approval makes it a direct pathway to roles within federal agencies and defense contractors — organizations including General Dynamics, Booz Allen Hamilton, and Leidos actively seek candidates with this credential.
As the capstone of the CompTIA Cybersecurity Career Pathway, SecurityX is positioned above Security+, CySA+, and PenTest+ and signals to employers that a candidate operates at the architect and integrator level rather than the analyst or administrator level. Compared to alternatives like CISSP (which is management-focused) or OSCP (which is offense-focused), SecurityX occupies a distinct niche as a hands-on, vendor-neutral credential validating advanced defensive architecture and engineering skills. Employers in both the public and private sectors — including Target, Ricoh, and Exxon Mobil — recognize the certification for senior technical security hiring.

Preview — answers shown1. Northwind's incident response team needs to collect volatile evidence from a compromised Windows server. Which order of data collection follows the correct order of volatility from most to least volatile? (Select one!)
Explanation
The correct order of volatility from most to least volatile is: CPU registers/cache → RAM/memory → Network state/connections → Running processes → Disk data → Remote logs/archival media. Data should be collected in this order because the most volatile data is lost first when a system is powered down or reboots. All other sequences collect less volatile data before more volatile data, risking evidence loss.
2. Contoso's vulnerability management team is overwhelmed with 15,000 identified CVEs. The CISO wants a risk-based prioritization strategy using CVSS v4.0 scores, EPSS probability data, and the CISA KEV catalog. Which approach provides the most effective prioritization strategy? (Select one!)
Explanation
Effective vulnerability prioritization requires combining multiple signals: CVSS provides technical severity (impact if exploited), EPSS provides the probability of exploitation in the next 30 days on a 0-to-1 scale, and the CISA KEV catalog identifies vulnerabilities with confirmed active exploitation requiring immediate action. Best practice prioritizes KEV entries first (actively exploited), then vulnerabilities with high CVSS scores combined with high EPSS scores. CVSS alone ignores exploitation probability and has been criticized for scoring inflation. EPSS alone ignores business impact. Focusing only on KEV misses emerging threats. SSVC provides organizational decision framework as an additional layer.
3. Tailspin Toys is implementing a Privileged Access Management (PAM) solution to secure administrative access to critical infrastructure. The security architect wants to minimize standing privileges and implement just-in-time access for system administrators. Which PAM capability best addresses this requirement? (Select one!)
Explanation
Just-in-time (JIT) privilege elevation directly addresses the requirement to minimize standing privileges by granting administrative access only when needed for a specific task and time period, then automatically revoking it afterward. This eliminates permanently elevated privileges, dramatically reducing the attack surface. Credential vaulting secures privileged credentials and prevents exposure but does not eliminate standing privilege assignments. Session recording provides valuable audit capabilities but does not reduce the duration or scope of privilege grants. Dual control adds approval workflows but does not inherently limit the time window of privilege assignment the way JIT access does. JIT access enforces least privilege on a temporal basis, which is foundational to privileged access security.
4. Fabrikam's application security team is implementing security testing throughout the Software Development Lifecycle (SDLC). They need to distinguish between different testing approaches. Which of the following correctly describes the differences between IAST and RASP technologies? (Select one!)
Explanation
IAST (Interactive Application Security Testing) is a testing technology that instruments applications with sensors during QA and testing phases to analyze code execution in real-time, combining elements of SAST and DAST to identify vulnerabilities with low false positives and provide precise code-level details about vulnerability location. RASP (Runtime Application Self-Protection) is a security protection technology that integrates into applications in production to monitor execution and actively block attacks in real-time by detecting and preventing exploitation attempts as they occur. IAST finds vulnerabilities during testing; RASP protects against attacks during production. The second option reverses their purposes entirely. The third option is incorrect; they are distinct technologies with fundamentally different purposes (testing versus protection). The fourth option is wrong; IAST complements but does not fully replace SAST and DAST since each finds different vulnerability types, and RASP is a protection mechanism rather than a testing approach, so it does not replace penetration testing which validates overall security posture.
5. Fabrikam Financial is presenting cybersecurity risk to the board of directors. The CISO needs to justify a $150,000 annual investment in a new email security platform. Historical data shows the organization experiences an average of 6 successful phishing attacks per year (ARO = 6), with each incident costing an average of $80,000 in remediation, legal fees, and lost productivity (SLE = $80,000). The new platform is projected to reduce successful phishing attacks to 1 per year. What is the Return on Security Investment (ROSI) for this email security platform? (Select one!)
Explanation
The ROSI calculation works as follows: Current ALE (before control) = SLE × ARO = $80,000 × 6 = $480,000 per year Future ALE (after control) = $80,000 × 1 = $80,000 per year ROSI = (ALE_before − ALE_after) − Cost_of_control ROSI = ($480,000 − $80,000) − $150,000 = $400,000 − $150,000 = $250,000 A positive ROSI of $250,000 clearly justifies the investment. The board should be presented with this financial metric rather than technical severity scores. The $230,000 option represents a common error of subtracting only the cost without computing the full ALE difference. The $150,000 option is just the cost of the control itself. The $330,000 option results from an incorrect partial calculation. ROSI is the correct metric for justifying security investments in business terms because it frames security spending as a financial decision with measurable return.
