Microsoft Entra Identity-First Access Replaces VPN Gaps

Introduction

Traditional VPNs were designed to extend network access, but they do not continuously evaluate identity, device posture, location, or risk. Microsoft’s latest guidance highlights why organizations should shift to an identity-first access model using Microsoft Entra to apply Zero Trust policies across all resources, not just Microsoft 365.

What’s new

Microsoft is emphasizing a broader Zero Trust approach built around:

• Conditional Access as the policy engine for evaluating identity, device state, location, application, and user risk
• Microsoft Entra Internet Access for threat-aware browsing, web content filtering, and granular SaaS controls
• Microsoft Entra Private Access for securing access to on-premises applications without relying on legacy VPN designs
• Global Secure Access to extend identity-driven controls across AI apps, SaaS, private apps, and internet sessions

The key message is that access decisions should be based on real-time signals and adjusted as risk changes, rather than granting broad network-level trust.

Why this matters for IT teams

For IT administrators and security teams, this approach reduces the gaps left by traditional VPNs and static firewalls. Instead of managing separate policy models for cloud apps, private apps, and internet traffic, teams can use a more unified framework based on identity and risk.

Potential benefits include:

• Reduced lateral movement from compromised accounts
• Faster automated responses to risk detections
• Lower complexity compared to VPN-heavy architectures
• Improved user experience by avoiding inconsistent remote access paths
• Better cost efficiency by reducing reliance on on-premises security hardware

This is especially relevant for enterprises adopting AI-enabled apps and unmanaged SaaS services, where traditional controls may not be applied consistently.

Recommended next steps

Organizations using Microsoft Entra should review whether Zero Trust policies currently cover:

• AI applications and copilots
• Non-federated or unmanaged SaaS apps
• On-premises applications
• General internet traffic and browsing sessions

Security teams should also evaluate how risk-based Conditional Access and Global Secure Access can work together to replace broad VPN access with least-privilege, policy-based access.

Bottom line

Microsoft’s message is clear: Zero Trust should extend beyond core cloud apps to every application, session, and resource. For enterprises modernizing remote access, Microsoft Entra identity-first access offers a path to stronger security, simpler operations, and more consistent policy enforcement across hybrid environments.
