Only 12% of CompTIA Security+ holders ever go on to earn the CASP+ cert. That gap isn't because the others aren't ambitious — it's because CASP+ is genuinely hard, and most people aren't sure whether the effort pays off. This guide breaks down what the certification actually covers, what kind of career it unlocks, and which prep courses are worth your time.
What the CASP+ Cert Actually Tests
The CompTIA Advanced Security Practitioner certification — universally shortened to CASP+ cert or just CASP cert — is CompTIA's highest-level security credential. Exam code CAS-004 covers six domains that lean heavily toward engineering and architecture rather than policy or compliance:
- Security Architecture — designing enterprise-grade security solutions across hybrid environments
- Security Operations — advanced threat detection, incident response, and SOC integration
- Security Engineering & Cryptography — PKI, cryptographic protocols, hardware security
- Governance, Risk & Compliance — risk frameworks, audits, regulatory alignment
- Security Integration of Emerging Technologies — cloud, IoT, OT, AI-adjacent attack surfaces
- Research & Collaboration — threat intelligence operationalization, cross-team coordination
The exam runs 165 minutes, caps at 90 questions, and mixes standard multiple-choice with performance-based items — meaning some questions drop you into a simulated environment and ask you to configure or troubleshoot something. There's no passing score published by CompTIA (it's scaled), but practitioners consistently report it as harder to prepare for than Security+, largely because of those performance-based items.
One structural detail that matters: CASP+ has no expiration date, but CompTIA's Continuing Education (CE) program requires 75 CE credits every three years to keep the cert active. In practice, most holders accumulate CE credits through conferences, vendor training, or higher certs like CISSP.
CASP+ Cert vs. CISSP: The Honest Comparison
This is the question that comes up in every security forum thread about CASP cert. Both target senior practitioners. Here's the actual difference:
- CISSP skews toward management and governance. The exam tests breadth across eight domains but rarely asks you to configure anything. It's the cert hiring managers recognize immediately.
- CASP+ skews toward hands-on engineering. It's for people who still want to be the one designing and implementing security architecture, not managing the people who do.
CISSP requires five years of paid work experience in two of eight CISSP domains before you can sit the exam. CASP+ recommends ten years of general IT experience (five in security) but doesn't enforce it as a hard gate — you can sit the exam without meeting those numbers. The experience recommendation exists because the content assumes you've already solved real security problems in production environments.
If you're deciding between the two: CISSP opens more doors in enterprise and government leadership roles. CASP+ is better if you want to stay technical and work as a security architect or senior engineer. Many practitioners hold both.
DoD 8140 and Why Government Jobs Specifically Ask for CASP+ Cert
The U.S. Department of Defense Directive 8140 (successor to DoD 8570) classifies CASP+ under IAM Level 3 and IASAE Level 2 and 3. In plain terms: federal agencies and defense contractors working on classified systems are required to have personnel with specific cert credentials. CASP+ satisfies those requirements for senior technical roles that CISSP or Security+ alone don't cover.
If you're targeting federal contractor work, DOD civilian positions, or cleared roles at defense primes like Lockheed, Raytheon, or Booz Allen, the CASP+ cert can function as a hiring requirement rather than just a differentiator. Job postings for cleared security architect roles in the DC corridor routinely list CASP+ as preferred or required.
This is the single strongest concrete use case for the cert. Outside government contracting, CASP+ carries less name recognition than CISSP — but within that ecosystem, it's specifically sought out.
Salary and Career Impact of the CASP+ Cert
CompTIA's own compensation data puts CASP+ holders at a median salary around $120,000–$135,000, but that number reflects the roles the cert targets more than the cert itself causing salary increases. People who earn CASP+ are typically already working as senior security engineers or architects — the cert validates their existing level rather than propelling them there from junior roles.
The realistic career path looks like this:
- Security+ → entry-level security analyst or SOC role ($60K–$80K)
- CySA+ or PenTest+ → mid-level analyst or pen tester ($80K–$100K)
- CASP+ → senior security engineer, security architect ($110K–$145K)
The jump from step 2 to step 3 is driven more by experience accumulation and portfolio than by holding the cert. CASP+ cert matters most when you're already qualified for senior roles and need to clear a credentialing gate — particularly in regulated industries and government.
Job titles associated with CASP+ cert holders include: Security Architect, Senior Security Engineer, Cybersecurity Consultant, Information Assurance Analyst, and Systems Security Engineer. These are almost all individual contributor roles at senior levels, not management tracks.
Top Courses to Prepare for the CASP+ Cert
Prep materials matter here more than most certs because the performance-based questions require practicing in simulated environments — not just reading concepts. These are the courses worth considering:
CompTIA CASP+ (CAS-004) Course
Structured directly around the CAS-004 exam domains, this Coursera course is the most direct exam-prep option available — useful if you want coverage that maps cleanly to what CompTIA actually tests, including the performance-based question types that trip up most first-time sitters.
CASP+ CompTIA Advanced Security Practitioner Study Guide
Wiley's approach goes deeper on conceptual grounding before drilling into exam specifics, which suits practitioners who want to actually understand the architecture principles behind the test rather than just pattern-match to answer choices — the difference matters on performance-based questions.
CASP+ Cert FAQ
How hard is the CASP+ cert exam?
Harder than Security+ by a meaningful margin. The performance-based questions require hands-on familiarity with configuring security tools and diagnosing realistic scenarios — they can't be crammed with flashcards. Most candidates who fail report being surprised by the depth of those items. Plan for 80–120 hours of study if you already have solid security experience; more if you're coming from a compliance or policy background rather than hands-on engineering.
How much does the CASP+ cert exam cost?
The CAS-004 exam costs $494 USD through CompTIA directly (2024 pricing). Vouchers are sometimes available at a discount through authorized training partners. If you're a government employee or active military, GI Bill and MyCAA benefits have historically covered CompTIA exams — check current eligibility with your education office.
What are the prerequisites for the CASP+ cert?
CompTIA recommends ten years of general IT experience including five years in hands-on security, but this isn't a hard gate — you can register for and sit the exam without verification. The recommendation exists because the content assumes fluency with concepts that usually take years to encounter in production environments. Sitting early and failing is expensive; the experience threshold exists for good reason.
Does CASP+ cert expire?
The credential itself doesn't expire, but to maintain active status you need 75 CE credits every three years through CompTIA's CE program. Eligible activities include vendor training, attending security conferences, publishing research, or earning higher certifications. Many holders naturally accumulate credits through their ongoing work without specifically tracking toward 75.
Is CASP+ cert worth it without a DoD job?
Outside government and defense contracting, CASP+ carries less brand recognition than CISSP. In private sector hiring, most senior security roles list CISSP as preferred. CASP+ is worth pursuing if: (a) you need DoD 8140 compliance for a specific role, (b) you've already positioned yourself in the CompTIA ecosystem and want the capstone, or (c) you want to prove technical depth specifically and aren't interested in CISSP's management-heavy content. For general private sector advancement, CISSP has better return on name recognition alone.
Can you pass CASP+ cert with only Security+ experience?
Technically possible but unlikely to succeed on the first attempt. Security+ validates foundational concepts; CASP+ tests applied architecture and engineering judgment across complex enterprise scenarios. The gap is real. Most successful CASP+ candidates have spent several years working in security operations, architecture, or engineering roles where they've encountered the types of tradeoffs the exam tests — not just read about them.
Bottom Line: Who Should Pursue the CASP+ Cert
Pursue CASP+ cert if you're a working security professional with substantial hands-on experience who needs to satisfy DoD 8140 requirements for a specific role, or who wants a rigorous technical benchmark without the management focus of CISSP. It's one of the few senior security credentials that stays firmly in the engineering lane rather than drifting toward compliance paperwork.
Skip it if you're early in your career, if your target roles are in private sector companies that primarily recognize CISSP, or if you'd rather invest the same study hours toward CISSP which opens more doors in enterprise leadership tracks. The CASP+ cert is excellent for what it is — but it's not the universal senior security credential that some study guides make it sound like. Know the specific door you're trying to open before you commit.
