How CompTIA Certifications Overlap
See exactly which topics are shared across A+, Network+, Security+, CySA+, and PenTest+. Plan your cert path around what carries over from one exam to the next.
Which CompTIA Certifications Share the Most Topics?
The matrix below marks where each topic area appears in each exam’s objectives. A check mark means the topic appears on that exam. The topic areas are our grouping, not CompTIA’s domains.
| Topic Area | A+ | Network+ | Security+ | CySA+ | PenTest+ |
|---|---|---|---|---|---|
| Networking Fundamentals | Covered | Covered | Covered | — | — |
| Network Security | — | Covered | Covered | Covered | Covered |
| Threat Analysis | — | — | Covered | Covered | Covered |
| Hardware & Troubleshooting | Covered | Covered | — | — | — |
| Cloud & Virtualization | Covered | — | Covered | — | — |

Check marks show where a topic appears, not how heavily it is tested. CompTIA publishes the official domain weights on each exam’s page.
What Carries Over When You Stack CompTIA Certs?
CompTIA certs share core topics, so studying one gives you a head start on the next. Nobody publishes a measured weeks-saved figure, so this list names what carries over instead.
A+ then Network+
Networking fundamentals and hardware troubleshooting overlap
Network+ then Security+
Network security, cryptography, and networking overlap
Security+ then CySA+
Threat analysis, incident response, and vulnerability management overlap
Security+ then PenTest+
Vulnerability management, network security, compliance, and access control overlap
CySA+ then PenTest+
Vulnerability management and threat analysis overlap. CySA+ is defensive, PenTest+ is offensive — complementary perspectives
Full trifecta (A+ then Net+ then Sec+)
Cumulative overlap across networking, security, and troubleshooting
Cyber pathway (Sec+ then CySA+ then PenTest+)
Security fundamentals carry through all three. CySA+ adds defensive depth, PenTest+ adds offensive depth
What Is the Best Order to Get CompTIA Certifications?
The best order depends on your career goal. Here are the most efficient paths based on topic overlap.
IT Support
Build from hardware fundamentals up through networking to security. The classic CompTIA trifecta.
Cybersecurity
Go straight into security, then specialize in analysis or penetration testing.
Networking
Same trifecta path, but with Network+ as your core focus and differentiator.
Career Changer
Skip Network+ if time-constrained. A+ gives foundations, Security+ opens the most doors.
Do You Need A+ Before Network+ or Security+?
No. CompTIA has no formal prerequisites for any certification.
You can take Security+ or Network+ without A+. But A+ covers the basics — operating systems, networking, troubleshooting — that show up on both exams. That foundation makes the harder certs easier.
CompTIA recommends CompTIA A+ certification, with 9 to 12 months of hands-on experience in a junior network administrator or network support technician role before Network+, and CompTIA Network+ and two years of experience working in a security/systems administrator job role before Security+. A+ is the usual first step if you are new to IT.
Bottom line: If you have IT work experience, you can skip A+ and go directly to Network+ or Security+. If you are starting from scratch, A+ first will save you time and frustration on the later exams.
CompTIA Certification Overlap FAQ
How much do CompTIA certifications overlap with each other?
This page groups A+, Network+, Security+, CySA+, and PenTest+ into 14 topic areas. That grouping is ours, not CompTIA's, and it shows where a topic appears, not how heavily it is tested. The biggest shared ground is between Network+ and Security+ (networking and cryptography), between Security+ and CySA+ (threat analysis, incident response, and vulnerability management), and between CySA+ and PenTest+ (vulnerability management from defensive and offensive sides). For a measured comparison, CompTIA's own acronym lists show 79 of Network+'s 199 acronyms also appear on A+.
Can I skip A+ and go straight to Security+?
Yes. CompTIA has no formal prerequisites for any certification. However, A+ covers operating systems and networking fundamentals that appear on the Security+ exam, so having that foundation helps. If you have IT work experience, you can often skip A+ without issues.
What is the CompTIA trifecta and why does it matter?
The CompTIA trifecta is A+, Network+, and Security+. CompTIA's recommended experience puts them in that order: A+ before Network+, and Network+ before Security+. Earning Security+ also renews A+ and Network+ if earned within their three-year cycle. In CompTIA's own acronym lists, 79 of Network+'s 199 acronyms also appear on A+.
How much study time can I save by stacking CompTIA certs?
No one publishes a measured figure, so treat any weeks-saved number with suspicion. Shared topics mean less brand-new material on the next exam, but each exam tests its topics at its own depth. Plan study time per exam based on what you already know.
Should I get Network+ or Security+ first?
For most people, Network+ first is the better path. CompTIA recommends CompTIA Network+ and two years of experience working in a security/systems administrator job role before Security+, and Security+ assumes you know how networks work. However, if you are specifically targeting cybersecurity roles and are short on time, Security+ alone carries more weight with employers.
