Introduction
In a constantly evolving security context, traditional VPN models show their limitations against modern threats. Microsoft Entra Global Secure Access introduces an advanced approach based on SSE (Secure Service Edge) and ZTNA (Zero Trust Network Access) to redefine remote access and integrate robust identity controls.

With emphasis on identities and session contexts, Entra Global Secure Access becomes the new "entry point" for Zero Trust. This article explores recent changes, deployment best practices, and practical benefits for IAM and SecOps teams.
Recent Evolution and Friction Points of Classic VPNs
What's the change?
VPN approaches attempt to control network access primarily through encrypted tunnels. However:
- Lack of granular identity: VPNs don't consider user identities or session contexts.
- Increased attack surface: Threats like credential theft or MITM attacks are amplified.
- Operational complexity: Managing multi-site configurations via VPN becomes a logistical nightmare.
In comparison, Microsoft recently introduced major evolution points in its SSE/ZTNA solutions:
- GA Support for Entra Internet Access and Private Access: Simplified access and enriched Zero Trust conditions.
- Integration with Conditional Access identity policy: Real-time risk enforcement.
- Maturity of logs and traffic shaping: Increased visibility into flows and critical events.
Good to know
SSE solutions like Entra offer globally distributed PoPs, ensuring performant and secure connections.
Capability Table: Status and Prerequisites
| Feature | Status (GA/Preview) | Prerequisites | Impact | Sources |

| Private Access | Preview | Conditional Access Configuration | Optimization of local access flows | Tech Community |
Myths vs Reality: Decoding
Myth 1: "SSE completely replaces VPN."
Reality: SSE reduces VPN dependencies but may require coexistence depending on legacy scenarios.
Myth 2: "Zero Trust eliminates all risks."
Reality: Zero Trust greatly reduces the impact of attacks, but remains fallible against compromised devices.
Myth 3: "SSE/ZTNA deployment is simple."
Reality: It requires clear understanding of dependencies (Conditional Access policy, licensing).
Myth 4: "User impact is invisible."
Reality: Some authentication or access flows may require UX adjustments.
Myth 5: "All sessions are protected by SSE/ZTNA without exception."
Reality: Practical exclusions (incompatible legacy sites and apps) may exist.
30/60/90 Day Action Plan
30 days: Pilot
Start by deploying Entra Internet Access on a test group, with strict Conditional Access policies.
