An Azure analytics service that brings together data integration, enterprise data warehousing, and big data analytics. Previously known as Azure SQL Data Warehouse.
Use this path if the workspace is affected by the retirement of the trusted services firewall exception.
- Confirm the workspace is in scope
The change mainly affects Synapse workspaces that access Azure Storage or Azure Key Vault by using a managed identity together with the trusted-services/firewall-exception model. Check:
- Whether the Synapse workspace uses managed identity
- Storage account networking settings
- Key Vault networking settings
- Whether trusted Microsoft services access is enabled
- Whether private endpoints are already configured
- Check whether the current workspace can use managed private endpoints Managed private endpoints are supported only in Azure Synapse workspaces that use a Managed workspace Virtual Network. If the workspace was created without a managed virtual network, it can't be enabled or changed later. In that case, create a new Synapse workspace with a managed virtual network and plan to migrate workloads to it.
- Create a Synapse workspace with a managed virtual network A managed virtual network is required to use managed private endpoints.
- Create managed private endpoints from Synapse to dependent resources
Create a managed private endpoint for the storage account (ADLS Gen2). This replaces the trusted services firewall exception with a private connection. Managed private endpoints:
- Are created inside the Managed Virtual Network associated with the Synapse workspace
- Send traffic over the Microsoft backbone network
- Are created in a Pending state first
- Must be approved by the owner of the target private link resource before traffic can flow
- Enable the required network settings
For Azure Synapse Link for Dataverse, both of these settings must be enabled for successful connection:
- On the storage account: Networking > Firewalls and virtual networks > enable Allow Azure services and resources to access this storage account
- On the Synapse workspace: Networking > enable Allow Azure services and resources to access this workspace
- If creating a private endpoint to the Synapse workspace itself, follow the portal flow
In Azure portal:
- Open the subscription and make sure the Microsoft.Network resource provider is registered
- If the private endpoint is created from a different subscription, also register Microsoft.Synapse in the subscription hosting the private endpoint
- Open the Synapse workspace
- Go to Security > Private endpoint connections
- Select + Private endpoint
- On Basics, choose Subscription, Resource Group, Name, and Region
- On Resource, select Connect to an Azure resource in my directory
- Select the subscription containing the Synapse workspace
- Select resource type Microsoft.Synapse/workspaces
- Select the workspace resource
- Choose the target sub-resource:
- Sql for dedicated SQL pools
- SqlOnDemand for built-in serverless SQL pool
- Dev for other Synapse workspace access
- On Configuration, select the Virtual network and Subnet
- Select Yes for Integrate with private DNS zone
- Complete Review + create
- After deployment, verify the new connection under Private endpoint connections
- If access to Synapse Studio is needed from a restricted network, use a private link hub
For Synapse Studio, create:
- An Azure Synapse private link hub
- A private endpoint from the virtual network to that hub
- If the environment is on a restricted network, add required outbound rules
Add outbound security rules for these service tags:
- AzureResourceManager
- AzureFrontDoor.Frontend
- AzureActiveDirectory
- AzureMonitor (optional, only when sharing data with Microsoft)
- Validate the final state
Confirm that:
- The workspace uses a Managed Virtual Network
- Managed private endpoints exist for required resources
- Private endpoint connections are approved
- Required DNS integration is configured where applicable
- The old trusted-services dependency is no longer the access path
- Scope clarification Based on the available guidance:
- The retirement is focused on Synapse access to Azure Storage and Azure Key Vault through managed identity plus trusted-services firewall exception
- Environments where Storage or Key Vault are fully open to public network access are not the primary scenarios impacted
- Azure SQL Database isn't covered by this specific retirement
Important: Changing firewall or network settings can remove access for legitimate clients if the private-link path is not fully ready. Approve private endpoint connections and validate connectivity before tightening public access.
