A few weeks ago, Microsoft announced the general availability of its Security Service Edge (SSE) offering, Global Secure Access (GSA). GSA encompasses Entra Internet Access, a cloud-based Secure Web Gateway, and Entra Private Access, a Zero Trust Network Access (ZTNA) solution for accessing private data and applications on-premises.

ZTNA vs. VPN

Entra Private Access will be a compelling alternative to traditional VPN solutions such as Windows Always On VPN. Where traditional VPNs grant the endpoint an IP address on the internal network, Entra Private Access provides more granular access and does not require the device to be directly connected to the network.

GSA Client

Administrators must install the GSA client on all endpoints using Entra Internet Access or Entra Private Access. Today, the client is available for Windows and Android devices. iOS and macOS clients are forthcoming.

Private Network Connector

The Entra Private Access solution relies on the Entra Private Network Connector. The Entra Private Network Connector is a software component installed on-premises that provides remote access connectivity. Previously, it was called the Azure AD Application Proxy. Essentially, it is the same technology extended to support TCP and UDP network access in addition to HTTP.

Limitations

Entra Private Access is the way of the future for secure remote access. However, today, there are still some important limitations associated with this technology.

Private DNS

Although Microsoft announced general availability for Entra Private Access, it still lacks the private DNS feature many organizations require to provide feature parity with their existing VPN. This feature is still in private preview at the time of this writing. Hopefully, Microsoft will release this feature soon.

Device Connection

Entra Private Access does not support device-based connections. This limits its capabilities for domain-joined devices. If your organization uses hybrid Entra join today, consider sticking with Always On VPN until you move to native Entra joined endpoints.

Licensing

Global Secure Access (Entra Private Access and Entra Internet Access) are included in the Microsoft Entra Suite license. More information about Entra licensing can be found here.
