How to access an Azure Storage account behind Azure Private Link using Microsoft Entra Private Access

Microsoft Entra Private Access lets you extend the security features of Azure Private Link to remote and on-premises users. Extending the security features brings modern authentication features, such as Conditional Access, to the front of Azure Platform as a Service (PaaS) resources.

Azure Private Link lets you access Azure PaaS Services such as Azure Storage and Azure SQL Database. Azure Private Link also lets you access your Azure hosted services and partner services over a private endpoint in your virtual network. The result is that resources like virtual machines (VMs) can privately and securely communicate with Private Link resources.

Prerequisites

Create a Global Secure Access application for the Azure storage account

  1. Sign in to the Microsoft Entra admin center as a Global Secure Access Administrator.
  2. Browse to Global Secure Access > Applications > Enterprise applications.
  3. Select New application.
  4. Choose the right connector group with the connector deployed in the private virtual network.
  5. Select Add application segment:
    • Destination type: FQDN
    • Fully Qualified Domain Name (FQDN): <fqdn of the storage account>. For example, storage1.blob.core.windows.net.
    • Ports: 443
    • Protocol: TCP
  6. Select Apply to add the application segment.
  7. Select Save to save the application.
  8. Assign users to the application.

Validate the configuration

Ensure connectivity to the storage account works from the connector machine. The connector is deployed on the same private virtual network.

Check connections to the storage account from outside the private virtual network. Computers that don't have the Global Secure Access client installed should fail. Computers that have the Global Secure Access client installed should succeed.
