Which might fit you

On the BLS projection, Network Administrator shows a projected decline of -4.2% (2024-2034) and Network Security Engineer shows projected growth of 8.2% (2024-2034). Network Security Engineer carries the stronger occupation outlook, which is one input to weigh — but Network Administrator can still be the right first step depending on your background and what you want to do.

Both roles sit at O*NET job zone 4, suggesting a comparable level of preparation to enter; the deciding factor is more likely the subject matter than the entry bar.

The two roles share foundational skills (Networking fundamentals), so progress toward one keeps the other within reach — useful if you are still deciding.

Network Administrator leans more on Troubleshooting.

Network Security Engineer leans more on Network security, Security fundamentals.

There is no single right answer here. Use the planner to see how your current background maps to each of Network Administrator and Network Security Engineer, then weigh the trade-offs above against what you actually want to spend your days doing.
