About CompTIA & Which Cert to Take First

Understanding the CompTIA cybersecurity pathway helps you choose the right exam to study for right now.

What is CompTIA?

CompTIA (Computing Technology Industry Association) is a non-profit IT trade association and the world's largest vendor-neutral certification body. Its certifications are ISO 17024 accredited and recognized globally by governments, defense agencies, and private employers. The CompTIA cybersecurity stack — Security+, CySA+, PenTest+, and SecurityX — forms a complete career progression from entry level to expert practitioner.

Security+ alone has over 700,000 holders worldwide and is consistently the most requested cybersecurity certification in job postings globally.

Which Certification Should You Take?

Start with Security+ (SY0-701) if you have 1–2 years of IT experience and are entering cybersecurity. It is the DoD 8570/8140 baseline for government roles and the most employer-recognized entry credential globally.

Choose PenTest+ (PT0-003) if you want to specialize in offensive security — penetration testing, ethical hacking, and red team operations. Recommended after Security+ with some hands-on experience.

Pursue SecurityX (CAS-005) if you have 10+ years in IT and 5+ in active security roles and want to validate senior-level architecture and engineering skills. This is CompTIA's top-tier expert credential.

Exam Domain Weights — All Three Certifications

Our domain-wise practice tests are mapped directly to these official exam objective weights, so your practice time is proportional to real exam emphasis.

Security+ (SY0-701) — 5 Domains

Domain 1: General Security Concepts (12%)  |  Domain 2: Threats, Vulnerabilities & Mitigations (22%)  |  Domain 3: Security Architecture (18%)  |  Domain 4: Security Operations (28%)  |  Domain 5: Security Program Management & Oversight (20%)

SecurityX (CAS-005) — 4 Domains

Domain 1: Governance, Risk & Compliance (20%)  |  Domain 2: Security Architecture (27%)  |  Domain 3: Security Engineering (31%)  |  Domain 4: Security Operations (22%)

PenTest+ (PT0-003) — 5 Domains

Domain 1: Engagement Management (13%)  |  Domain 2: Reconnaissance & Enumeration (21%)  |  Domain 3: Vulnerability Discovery & Analysis (17%)  |  Domain 4: Attacks & Exploits (35%)  |  Domain 5: Post-Exploitation & Lateral Movement (14%)

How Our Practice Tests Are Built

Every test is structured to simulate the real exam, not just expose you to random questions.

Mixed-Set Tests

Questions are distributed across all domains proportional to the official exam objectives. If Security Operations is 28% of the real Security+ exam, it makes up 28% of every mixed-set practice test — so your practice mirrors the real distribution.

Use mixed-set tests first to get a baseline score and identify which domains need the most work.

Domain-Wise Tests

Each domain-wise test isolates a single exam domain with 20 focused questions. This lets you drill specific weak areas without wading through questions from topics you already know well.

Use domain-wise tests after your mixed baseline to sharpen the areas where you scored lowest. Rotate between both test types in the final two weeks before your exam.

Frequently Asked Questions

Common questions about CompTIA exams and these free practice tests.

Is Security+ the right starting point for a cybersecurity career?
+
Yes — Security+ (SY0-701) is widely considered the best entry-to-intermediate cybersecurity certification globally. With 700,000+ holders, it is the most requested security certification by employers worldwide, satisfies DoD 8140 baseline requirements for multiple government roles, and provides a vendor-neutral foundation that supports advancement toward CySA+, PenTest+, SecurityX, and ISC2 certifications. CompTIA recommends 2 years of IT experience before attempting it, though many candidates without that background pass with focused study.
What is the difference between Security+ and SecurityX (CAS-005)?
+
Security+ (SY0-701) is an entry-to-intermediate certification validating foundational cybersecurity skills — scored 750/900, 90 questions in 90 minutes, fee $425. SecurityX (CAS-005) is an expert-level practitioner certification for senior security architects and engineers — scored pass/fail, up to 90 questions in 165 minutes, fee $529. SecurityX was formerly called CASP+ and was rebranded in December 2024. Most professionals take Security+ first, then build several years of hands-on experience before attempting SecurityX.
How many free practice tests are available for each CompTIA exam?
+
Security+ has 15 total tests (10 mixed-set + 5 domain-wise) covering 200 questions. PenTest+ has 10 total tests (5 mixed-set + 5 domain-wise) covering 200 questions. SecurityX has 9 total tests (5 mixed-set + 4 domain-wise) covering 180 questions. All tests are completely free — no login or subscription required.
Does Security+ satisfy DoD 8570 / DoD 8140 requirements?
+
Yes. CompTIA Security+ is approved under DoD Directive 8140 (the successor to 8570) as a baseline certification for IAT Level II and IAM Level I positions. SecurityX and PenTest+ are also DoD 8140 approved. These certifications are among the most common requirements in U.S. government and defense contractor cybersecurity job postings.
What is the difference between PenTest+ and SecurityX for offensive security?
+
PenTest+ (PT0-003) is an intermediate certification focused entirely on the penetration testing engagement lifecycle — scoping, reconnaissance, exploitation, and reporting. SecurityX (CAS-005) is an expert-level certification covering the full breadth of enterprise security architecture and engineering, with offensive security as one component alongside GRC, cloud security, and security operations. Choose PenTest+ to specialize in offensive security roles. Choose SecurityX to move into senior architecture and leadership roles that span both offensive and defensive security.
When does the current CompTIA Security+ (SY0-701) expire?
+
CompTIA typically retires Security+ versions approximately three years after launch. SY0-701 launched on November 7, 2023, so the estimated retirement window is late 2026. CompTIA has not officially announced a retirement date or confirmed plans for an SY0-702. Always check comptia.org for the current official exam status before purchasing a voucher.
