If you’re working in DoD IT or trying to break into the IC, the order in which you stack CompTIA certs matters more than most guides will tell you. The wrong sequence wastes months and leaves you billing at a lower rate than you should be.
This is the sequence that maps to DoD 8140 baselines, maximizes your contract value, and keeps study overlap high.
Start with Security+
Security+ is the linchpin. It satisfies the IAT Level II baseline, which is the floor for most cleared sysadmin and network roles. More importantly, it shares substantial domain overlap with every cert that comes after it — which means your study time compounds.
Timeline: 6–10 weeks for someone with 1–2 years of IT experience.
Don’t skip A+ or Network+ to get here faster. If you don’t already have solid networking fundamentals, the Security+ exam will feel like reading a foreign language. The 6 weeks you spend on Network+ pays back triple on Security+.
Network+ Before Security+ (If You Need It)
If you’re coming from a non-technical background — helpdesk, program management, admin side of cleared work — Network+ is not optional. It’s the vocabulary prerequisite.
If you already work in a sysadmin or network engineering capacity, you can skip it.
CySA+ Is Your Second Milestone
Once you have Security+, CySA+ (CS0-003) is the natural next step. It satisfies the IAT Level III / CSSP Analyst baseline and commands a meaningful pay bump at most contracting shops.
The exam leans heavily on behavioral analytics, threat detection, and SIEM workflows — which is exactly where cleared blue team work lives. If your current contract involves any SOC or CNDSP work, CySA+ is the highest-leverage cert you can hold.
Timeline: 8–12 weeks after Security+.
CASP+ vs. CISSP: Know the Difference
Both satisfy IAT Level III / IAM Level III baselines. Here’s the honest breakdown:
- CASP+ is a practitioner-level exam — hands-on, scenario-based, no prerequisite experience hours. Better fit for technical ICs doing architecture or engineering work.
- CISSP is a management-level exam and requires 5 years of paid security experience. Better fit for PMs, program directors, and anyone moving toward a security officer role.
Most technical cleared professionals should target CASP+ first. CISSP can come later if you’re moving into leadership.
The Optimal Sequence
- Network+ (if needed) → satisfies networking fundamentals
- Security+ → IAT Level II baseline, unlocks most cleared roles
- CySA+ → IAT Level III, blue team ops, meaningful raise
- CASP+ or CISSP → senior technical or leadership track
One Thing Most Guides Get Wrong
They treat cert order as a purely academic decision. In the cleared world, it’s a contract value decision. Every baseline tier shift typically adds $10–25k to your annual rate at a mid-tier contracting shop, and significantly more at prime contractors or IC agencies.
Sequence your certs to hit baselines, not to collect credentials.
