What is CompTIA CASP+?
CompTIA CASP+ (CompTIA Advanced Security Practitioner) is the highest-level certification in the CompTIA security track. The current version is CAS-004. It's positioned above both CySA+ and Security+ and is designed for senior security engineers, architects, and practitioners who implement and manage enterprise security solutions.
The key distinction that sets CASP+ apart from other advanced security certifications is its focus on doing rather than managing. CASP+ is explicitly a practitioner cert — the exam assumes you are the person implementing security controls, not the person approving them. If your career goal is to stay hands-on at a senior level rather than move into security management, CASP+ is the CompTIA path that gets you there.
Unlike most CompTIA exams that give you a score out of 900, CASP+ is pass/fail only. You won't receive a numerical score — you either pass or you don't. This is intentional: CompTIA considers CASP+ a mastery-level exam where passing demonstrates expert-level competency, not a gradation of performance.
CASP+ exam domains (CAS-004)
The CAS-004 exam covers four domains. Security architecture and engineering together account for over 60% of the exam — this is fundamentally a design and implementation cert, not a policy cert.
CASP+ vs CISSP — which should you pursue?
This is the most common question about CASP+, and the answer comes down to career direction rather than which cert is objectively better. Both are respected advanced security credentials. They serve different audiences.
| Category | CASP+ (CAS-004) | CISSP |
|---|---|---|
| Issuer | CompTIA | (ISC)² |
| Orientation | Practitioner / hands-on technical | Management / policy / governance |
| Experience required | Recommended, but not enforced | 5 years paid experience (required) |
| Exam cost | ~$494 | ~$749 |
| Questions | Up to 90 (PBQ heavy) | 125–175 adaptive questions |
| Passing score | Pass/Fail | 700 / 1000 |
| Renewal | Every 3 years | Every 3 years (CPE required) |
| DoD 8570 | IAT III, IAM II/III | IAM Level III |
| Best for | Senior engineers and architects staying technical | Security managers, CISOs, governance roles |
| Market recognition | Strong in DoD/government; growing in enterprise | Widely recognized globally, especially in enterprise and finance |
| Salary impact | $100,000 – $140,000+ | $110,000 – $160,000+ |
The practical rule: if you want to stay technical and hands-on, pursue CASP+. If you want to move into security leadership, management, or CISO-track roles, CISSP is the more recognized credential for that path. Many senior practitioners hold both eventually.
How hard is CASP+?
CASP+ is widely considered one of the harder CompTIA exams. The performance-based questions are significantly more complex than those on Security+ or CySA+ — you're expected to design solutions, not just identify problems. Scenarios involve enterprise-scale architectures, competing business and security requirements, and situations where there is no single "right" answer, only the most defensible one given the constraints.
The pass/fail grading adds psychological pressure. You put in hundreds of hours of study and walk out not knowing your score — just pass or fail. Candidates who underestimate the exam because they sailed through Security+ or CySA+ are the ones most likely to fail on the first attempt.
You need real-world experience to pass CASP+, not just study time. CompTIA recommends 10 years of IT experience with 5 in security — not as a gatekeeping requirement, but because the exam scenarios reflect situations you won't understand without having lived them. Candidates who take CASP+ early in their career as a shortcut to advanced credentials often fail multiple times.

CASP+ salary and job roles
| Job Title | Typical Salary Range (US) |
|---|---|
| Security Architect | $110,000 – $160,000 |
| Senior Security Engineer | $105,000 – $150,000 |
| Principal Security Engineer | $130,000 – $180,000 |
| Penetration Tester (Senior) | $100,000 – $145,000 |
| Security Operations Manager | $105,000 – $155,000 |
| Information Security Officer | $115,000 – $165,000 |
CASP+ is particularly valuable for DoD and federal contractor positions. It satisfies IAT Level III requirements under DoD 8570/8140, which are required for the most senior technical security roles in government IT environments. If you're on a DoD contractor career path, CASP+ is often required for promotion into senior technical positions.
Who should pursue CASP+?
Where CASP+ fits in the CompTIA path
CASP+ sits at the top of the CompTIA security certification stack. There is no CompTIA cert above it. Most candidates reach CASP+ after 8–12 years of IT experience, with the last 4–6 spent in security-focused roles.
A+ → Network+ → Security+ → CySA+ → CASP+
You don't need every cert in this sequence. Many CASP+ candidates skip CySA+ entirely and move from Security+ to CASP+ after accumulating sufficient experience. The sequence matters less than the experience level — CASP+ assumes you've done the work, regardless of which certs you hold.
Start with the foundation
If you're working toward CASP+, make sure your Security+ and CySA+ knowledge is solid first. See the best study resources for each:
