Direct answer: Compare ZTNA and VPN by the access they permit and the controls you can operate. ZTNA can apply access policies to specific applications; a VPN’s effective exposure depends on routing, segmentation and policy. Neither technology eliminates security risk by itself.
Define the applications and users first
Inventory private applications, protocols, administrators, remote users and unmanaged devices. Record which resources each group needs, how identity is verified and how access is revoked. Include emergency access and dependencies that could affect a migration.
Check a proposed product against the requirements
Microsoft documents Private Access as access to defined internal resources through Global Secure Access, including per-application access controls. Confirm the current deployment and licensing prerequisites for your environment. Microsoft Entra Private Access overview. Reference checked 2026-09-24.
Do not assume Private Access is simply a renamed Application Proxy or that an existing Entra ID P2 subscription includes every required capability. Confirm the current licenses, supported clients, connector requirements and application compatibility directly with Microsoft before procurement.
Pilot the migration and measure the result
Test representative applications and users before changing everyone’s access. Compare connection reliability, authorization results and observed performance using the same tasks. Keep a rollback plan, review logs and retire old access only after acceptance. The outcome depends on the actual design and workload; no universal speed improvement is promised.
Review managed security services or discuss access requirements.
