Can Microsoft Entra Private Access Resolve Zero-Trust Network Issues Better Than VPNs?

Remote work, hybrid infrastructure, cloud applications, and distributed users have changed how organizations approach network security. Traditional VPNs can provide remote connectivity, but connecting a user to a corporate network does not automatically follow the Zero Trust principle of granting access only to what is required. This is where Microsoft Entra Private Access provides a different approach. Instead of treating the network as the primary security boundary, it uses identity, application-level access, and policy controls to connect users with private resources.

Why VPNs Can Create Zero-Trust Network Issues

VPNs were designed primarily to provide secure network connectivity. Once authenticated, however, users may receive access to broad portions of the corporate network depending on how the VPN is configured.

This can create several challenges:

• Excessive network-level access

• Greater opportunities for lateral movement

• Difficulty applying application-specific policies

• Complex management across hybrid environments

• Dependence on traditional network perimeters

• Limited alignment between identity and network access decisions

These challenges do not mean that every VPN is insecure. Properly configured VPNs can still provide valuable protection. The issue is that network-level connectivity alone does not fully address modern Zero Trust requirements.

How Microsoft Entra Private Access Works

Microsoft Entra Private Access is part of Microsoft's Global Secure Access solution and is designed to provide Zero Trust Network Access (ZTNA) to private corporate resources. It can provide access to private applications, IP addresses, ports, and protocols without requiring a traditional VPN connection. The solution uses the Global Secure Access client and private network connectors to broker connections between users and internal resources. Organizations can define which private resources users can access and apply Microsoft Entra Conditional Access policies to those apps.

This shifts the security model from:

“Connect to the network, then access resources”

to:

“Verify the user and device, apply policy, and provide access to the required resource.”

Microsoft Entra Private Access vs. Traditional VPNs

The biggest difference is the level at which access is controlled.

A traditional VPN commonly establishes a network tunnel that can provide connectivity to a broader internal environment. Microsoft Entra Private Access, by contrast, supports granular application segmentation. Organizations and firms can create private access applications, assign users or groups, and apply Conditional Access policies to control access.

The comparison does not mean Microsoft Entra Private Access is automatically better for every organization. Existing infrastructure, application architecture, licensing, endpoint requirements, and migration complexity all need to be considered.

Can It Address Common Zero-Trust Challenges?

1. Reduce Excessive Network Access

With per-app access, business organizations can define specific IP addresses, FQDNs, ports, and protocols instead of simply placing users on the broader corporate network. This supports a more granular least-privilege model.

2. Strengthen Identity-Based Access

Microsoft Entra Private Access integrates with Microsoft Entra ID and Conditional Access. Organizations can use policies involving users, groups, authentication requirements, and device-related signals before granting access to private applications. For higher-value resources, Microsoft also documents using Privileged Identity Management with Private Access to support just-in-time privileged access.

3. Support Hybrid and Multicloud Environments

Modern companies and organizations depends on operating from a single data center. Private applications may exist across on-premises environments, private networks, hybrid infrastructure, and cloud platforms. Microsoft Entra Private Access is designed to provide remote access to private resources across these environments without requiring users to connect through a traditional VPN.

4. Support a Gradual VPN Transition

Organizations do not necessarily have to replace a VPN overnight. Microsoft recommends using Quick Access as a transition approach and then moving toward more granular per-application access as the Zero Trust architecture matures. This allows IT teams to begin with broader private-resource access, evaluate traffic and applications, and progressively introduce application segmentation.

What Organizations Should Consider Before Replacing VPNs

Moving to Microsoft Entra Private Access still requires planning. Organizations and firms need to identify private applications, users, groups, network destinations, protocols, and existing access dependencies. The Global Secure Access client is also required on supported end-user devices for Private Access scenarios, while private network connectors need to be deployed to broker connectivity to internal resources. Most importantly, organizations should avoid simply recreating broad VPN-style network access. Microsoft specifically notes that overly broad application segments can reproduce the excessive-access model associated with traditional VPNs.

Conclusion

Microsoft Entra Private Access can address several limitations associated with traditional VPN-based remote access by moving security controls closer to users, identities, devices, and apps. Its strongest Zero Trust value comes from granular access, Conditional Access integration, application segmentation, and identity-aware policies rather than simply replacing one network tunnel with another. For business organizations modernizing remote access, the practical path may be to use existing VPN infrastructure during transition, introduce Microsoft Entra Private Access, and progressively move from broad network connectivity toward application-specific Zero Trust access.
