Security+ vs Network+: which should you take first?

Short answer: for most people, Network+ first, then Security+. Networking is the foundation that security is built on. But if you already understand networking — or a job requires Security+ specifically — going straight to Security+ is completely valid.

CompTIA A+, Network+, and Security+ form the classic "core" certification trio, and the most common question is where Network+ and Security+ fall in that order. Neither has a formal prerequisite, so the right answer depends on your background and goals. Let's compare them head to head.

Security+ vs Network+ at a glance

What each certification covers

Network+ (N10-009)

Network+ teaches how networks actually work: the OSI model, IP addressing and subnetting, routing and switching, wireless, cloud and network architectures, network operations, and a structured approach to troubleshooting. It's vendor-neutral, so unlike the CCNA you're not learning one company's command line — you're learning the concepts that apply everywhere.

Security+ (SY0-701)

Security+ is the entry point to cybersecurity. It covers general security concepts, threats and vulnerabilities, security architecture, security operations, and governance, risk & compliance. Much of it assumes you already understand how networks and systems communicate — which is exactly why networking knowledge helps.

Why Network+ usually comes first

• It's the foundation. You can't secure what you don't understand. Firewalls, segmentation, VPNs, and intrusion detection all make far more sense once you know how traffic flows.
• It makes Security+ easier. A big chunk of Security+ rests on networking concepts. Learning them first means Security+ feels like applying knowledge rather than learning two subjects at once.
• Career-wise it mirrors the real path. Many people move into security through networking or help-desk roles, so the cert order matches the job progression.

When to take Security+ first instead

Plenty of people skip straight to Security+, and that's fine when:

• You already understand networking from school, work, or a cert like CCNA — Network+ would be partly review.
• A job or clearance requires it. Security+ is approved for U.S. Department of Defense IT roles (DoD 8140/8570), so it's frequently a hard requirement for government and contractor positions. If that's your target, go straight for it.
• You're aiming squarely at cybersecurity and want the most market-relevant cert first. Security+ appears in far more security job postings than Network+.

Is Security+ worth it?

Yes — it's one of the most recognized entry-level cybersecurity certifications. It's DoD-approved, regularly required or preferred in security job listings, and it's a strong stepping stone toward roles like security analyst, SOC analyst, and systems administrator. For anyone serious about breaking into security, it's close to a must-have.

The smart way to study either one

Both exams include performance-based questions (PBQs) — scenario tasks, not just multiple choice — so passive reading isn't enough. The most efficient prep combines adaptive practice questions that target your weak spots with full, timed mock exams so you're ready for the clock and the PBQs on test day.
