ZTNA vs Legacy VPN
Legacy VPNs put a remote user on the network and hope segmentation holds, which is why a single phished credential often reaches far more than it should. Zero trust network access grants access to specific applications based on identity, device posture, and context, with no implicit network reach. The migration is gradual: start with the highest-risk apps and keep VPNs for what truly needs network-level access.
Kernpunten
- Inventory which apps and users actually need VPN access before planning migration.
- Start ZTNA with high-risk or internet-facing applications and a small user group.
- Enforce device posture, MFA, and context checks on every access request.
- Remove broad network access and replace it with per-application policies.
- Keep VPNs for legacy protocols and systems that cannot support modern access.
- Log and review access decisions to tune policies and catch anomalies.
- Test failover and offline scenarios so users are not blocked during incidents.
- Measure reduction in exposed attack surface as the migration progresses.
Veelgestelde vragen
Does ZTNA replace the firewall?
No. It complements network controls by moving enforcement to identity and application.
Is VPN dead?
Not yet. Many legacy systems still need network-level access.
What is the biggest migration blocker?
Applications that assume network proximity or use legacy protocols.
How long does migration take?
Months to years depending on app count and legacy dependencies.
