As hybrid work becomes the norm and legacy infrastructure continues to coexist with cloud-native services, organisations face a growing challenge: how to secure access to on-premises resources without compromising agility or user experience. Microsoft’s public preview of Entra Private Access for Domain Controllers is a game-changer. As a Microsoft Solutions Partner in Azure Infrastructure, Modern Work, and Security, Velocity Technology Group is ready to help our clients lead the way.

🔐 The Problem with Traditional VPNs

VPNs have long been the default method for remote access to internal resources. But they’re increasingly seen as a security liability:

• Overly broad access: VPNs often expose entire networks rather than specific services.
• Lack of identity awareness: Access is granted based on network location, not user identity.
• Poor segmentation: Once inside, users can move laterally across systems.
• Limited visibility and control: Security teams struggle to enforce granular policies or monitor access effectively.

🌐 Microsoft Entra Private Access: A Zero Trust Approach

Microsoft Entra Private Access replaces VPNs with identity-driven, policy-based access to private resources. The new capability for Domain Controllers adds a critical layer of protection to one of the most sensitive components of any IT environment.

Key Features and Benefits

• Conditional Access for Legacy Authentication
  By intercepting Kerberos traffic at the domain controller level, Entra Private Access applies Conditional Access policies—even for systems that don’t support modern authentication protocols.
• Granular Access Control
  Define service-level access policies (e.g., RDP, SMB, LDAP), dramatically reducing the attack surface and aligning with Zero Trust principles.
• Privileged Identity Management Integration
  Admin access to domain controllers can be tightly controlled using Microsoft Entra PIM, ensuring elevated privileges are only granted when needed.
• Break Glass Mode
  Emergency access paths maintain security while ensuring operational continuity.
• Hybrid-Optimised Architecture
  Authentication traffic is routed securely to Microsoft Entra ID, while application traffic remains local—ensuring low latency and minimal disruption.

🆚 How Microsoft Entra Compares to Zscaler & Fortinet

As organisations evaluate their SASE and ZTNA strategies, Microsoft Entra Private Access offers a compelling alternative to traditional providers like Zscaler and Fortinet.

Microsoft’s identity-first architecture enables granular, policy-driven access without additional infrastructure, making it ideal for organisations already invested in Microsoft 365 and Azure.

🔄 Coexistence & Flexibility

Microsoft Entra Private Access supports coexistence with existing SASE stacks, allowing organisations to:

• Route private app traffic via Entra, while maintaining internet access via Zscaler or Fortinet.
• Phase in Zero Trust controls without disrupting existing workflows.
• Optimise licensing and reduce complexity by leveraging existing Microsoft entitlements.

This flexibility is ideal for enterprises transitioning from legacy VPNs or multi-vendor SASE stacks.
