Traditional VPNs create network-level trust: once connected, a user can often reach more of the private network than the task requires. Microsoft’s September 16, 2026 Entra guidance describes a more precise path: use Microsoft Entra Private Access to replace broad VPN access with identity-driven, per-app connectivity and phase the change around evidence.
Private Access is part of Microsoft’s Global Secure Access security service edge. It extends Entra application proxy to private resources, ports, and protocols, while Conditional Access and device signals help decide whether a session should be allowed.
Why VPN replacement is an operating-model change
A VPN is not only a tunnel. It is a dependency for remote access, help-desk procedures, firewall rules, incident response, and business continuity. Replacing it changes how the organization expresses least privilege. The target state is not “all traffic through a new client”; it is a set of explicit application access decisions based on identity, device health, location, and risk.
| Control question | VPN default | Private Access direction |
|---|---|---|
| What does a remote user reach? | A network segment or broad route. | A private app, IP range, FQDN, port, or protocol scoped to the role. |
| How is access decided? | Credentials plus network membership. | Identity, device compliance, risk, and Conditional Access policy. |
| How is the service operated? | Gateway capacity, tunnels, split-tunnel rules, and client support. | Connectors, traffic profiles, policy telemetry, and application ownership. |
Follow Microsoft’s five-step sequence
- Map the private estate: list private applications, file shares, internal web resources, owners, users, devices, sensitivity, and current VPN dependencies.
- Strengthen the identity foundation: require MFA where appropriate, review compliant-device conditions, emergency access accounts, exclusions, and report-only policies.
- Deploy Private Access: place private network connectors near the resources, define application-level policies, install the Global Secure Access client for the pilot, and validate the user experience.
- Monitor and respond: measure sign-in success, application behavior, user risk, device signals, session activity, help-desk volume, and policy effectiveness; connect the relevant telemetry to Microsoft Sentinel when appropriate.
- Retire VPN responsibly: update governance and fallback procedures, then remove VPN dependencies one application group at a time.
Design a pilot that can fail safely
| Pilot dimension | Recommended starting scope | Evidence to retain |
|---|---|---|
| Applications | Two or three representative private apps with different protocols and owners. | Connector placement, ports, DNS behavior, authentication flow, and owner sign-off. |
| Users and devices | A small group that includes remote, office, managed, and exception scenarios. | Device compliance, Conditional Access results, client version, and support notes. |
| Success measures | Sign-in success, app function, latency, policy accuracy, and help-desk contacts. | Before/after metrics, user feedback, incident record, and expansion decision. |
| Fallback | A documented temporary route for each critical application. | Tested break-glass access, owner, expiry, and rollback trigger. |
Keep the first pilot narrow enough that a failed connector or policy can be isolated. Do not decommission a VPN gateway simply because a test group can sign in; the migration is complete only when the business owner accepts the application behavior and the operations team can support it.
Use Quick Access as a bridge, not the finish line
Microsoft Learn positions Quick Access as a transition phase for a Zero Trust journey. It can help replace a VPN while the team learns the service, but the long-term control is per-app access with application segmentation and granular policies. Make that progression explicit in the architecture decision record so a temporary broad rule does not become the permanent design.
Licensing and operational gates
Verify the current Entra licensing and Global Secure Access prerequisites before committing to a production schedule. Confirm the Global Secure Access Administrator role, connector placement, client deployment method, DNS behavior, Conditional Access dependencies, and monitoring ownership. Run report-only policies and test emergency access before enforcing a new access path.
Private Access can coexist with existing non-Microsoft security service edge solutions during the transition. That makes a controlled migration possible, but it also means the team must document which client acquires which traffic and which policy is authoritative for each application.
Frequently asked questions
Does Entra Private Access replace every VPN immediately? No. Start with visibility, a Zero Trust foundation, a pilot, measured waves, and tested fallback procedures.
What is the difference between Global Secure Access and Private Access? Global Secure Access is the umbrella; Private Access is the capability for private corporate resources and VPN replacement.
What should a first pilot measure? Sign-in success, application behavior, latency, help-desk volume, policy effectiveness, and fallback readiness.
When should the VPN be retired? Incrementally, after each migrated application works, monitoring is live, governance is updated, and fallback has been tested.
