Something shifted in the last 18–24 months—and if you’ve been working in networking or security, you’ve probably felt it. Traditional VPN-heavy architectures are quietly dying, replaced by something far more fragmented, cloud-driven, and frankly… harder to troubleshoot.

The Shift from VPN to Zero Trust and SSE

Companies aren’t just “modernizing”—they’re being forced to rethink how access works. Remote users, SaaS apps, unmanaged devices… the old perimeter model simply doesn’t hold. This is where Zero Trust Network Access (ZTNA) and Security Service Edge (SSE) step in.

Instead of granting network access, you grant application-level access. Sounds clean in theory. In practice? It’s messy. Policies overlap. Identity providers behave inconsistently. Endpoint posture checks fail silently.

And this is exactly where the NSE7_SSE_AD-25 becomes relevant. It’s not teaching you theory—it’s forcing you to deal with those messy realities.

Market Growth and Demand for SASE Skills

Let’s be blunt: this isn’t hype. The SASE market is projected to exceed $28.5 billion by 2028 . That’s not incremental growth—that’s a full architectural shift.
