If you're starting an IT career, you've probably stared at CompTIA's certification roadmap and wondered where to begin. A+, Network+, Security+ — they stack, but the order matters more than most people admit.
Here's the honest breakdown.
Start with A+ if you're brand new.
A+ (220-1201 and 220-1202) is the foundation: hardware, operating systems, troubleshooting methodology, plus basic networking and security concepts. If you've never worked a help desk or built a PC, this is where you learn to think like a technician. It's also the cert hiring managers still scan for on entry-level resumes.
Take Network+ when you're ready to understand what's actually happening on the wire.
Network+ (N10-009) is where a lot of people hit their first wall — subnetting, routing, DNS, DHCP. It's the cert that separates "I can follow a setup wizard" from "I understand the network." If you want to go anywhere near system administration, cybersecurity, or Cisco's CCNA, this knowledge is non-negotiable.
Security+ is the payoff — but don't skip to it.
Security+ (SY0-701) is the most in-demand of the three in actual job postings, especially anything with "analyst" in the title. But it's built on the other two. Cryptography makes a lot more sense when you understand networking. Threat analysis lands better when you've troubleshot real systems. People who jump straight to Security+ usually end up memorizing instead of understanding — and it shows in interviews.
The order I'd recommend: A+, then Network+, then Security+. It's the classic trifecta for a reason — each one makes the next one easier. Study them as a sequence and you'll spend less total time than bouncing around.
That's exactly why we built the CompTIA Trifecta bundle: full study guides and 100-question practice packs for all three exams, in the order you'd actually study them. But regardless of how you study, learn them in sequence. Your future self — and your interviewers — will thank you.
Good luck. If you're studying now, you're already ahead of everyone still thinking about it.
