Finishing a networking fundamentals course is a real milestone, but it naturally raises the next question: what actually comes after this? Fundamentals are foundational by design — they’re not meant to be the entire destination. Here’s a realistic roadmap for what to do with that base.
Option 1: General Certification to Build Credibility
For many people, the next logical step is a broad, vendor-neutral certification that validates the fundamentals you’ve just learned in a form employers recognize. This is especially useful if you’re trying to break into your first IT role and don’t yet have professional experience to point to — a recognized certification substitutes for that missing track record in the eyes of a hiring manager screening resumes.
Option 2: Specialize Into Security
If security interests you more than pure infrastructure work, fundamentals plus a security-focused specialization is a strong combination — firewall and security platform administration, Zero Trust and SASE concepts, or vendor-specific platforms like Zscaler all build directly on the networking foundation you already have. This path tends to have strong demand currently, since security specifically has a persistent, well-documented talent shortage across the industry.
Option 3: Specialize Into Cloud Infrastructure
Cloud platforms (AWS, Azure, GCP) have their own networking concepts — virtual networks, security groups, load balancers — that map directly onto traditional networking fundamentals but require learning provider-specific implementation details. This path suits people more interested in infrastructure and systems work than security specifically, and cloud skills remain broadly in demand across nearly every industry.
Option 4: Go Deeper Into Traditional Networking
Some people find they genuinely enjoy the infrastructure layer itself — routing, switching, WAN design — enough to pursue advanced, vendor-specific networking certifications and specialize as a dedicated network engineer rather than branching into security or cloud. This remains a viable, well-compensated path, particularly for organizations with complex on-premises or hybrid infrastructure that isn’t going away anytime soon.
What We’d Recommend Thinking Through
The honest answer to “what’s next” depends on what you actually find engaging, not just what pays the most on average — all of these paths have real demand, and burning out pursuing a specialization you don’t enjoy because it looked good on a salary survey tends to backfire. Spend some time exposed to each area (security, cloud, traditional networking) before committing deeply to one.
A Practical Next Step
If security interests you, our Zscaler training is a strong next step that builds directly on networking fundamentals. If you want to explore Zero Trust and SASE concepts more broadly before committing to a specific platform, that’s covered in our Zero Trust & SASE content as well. Whatever direction you choose, the fundamentals you’ve already built are the foundation every one of these paths sits on top of — that investment doesn’t get wasted no matter which way you go next.
