The Minimal Transport Layer Security (TLS) Version setting allows customers to control the version of TLS used by their Azure SQL Managed Instance.
At present we support TLS 1.0, 1.1 and 1.2. Setting a Minimal TLS Version ensures that subsequent, newer TLS versions are supported. For example, e.g., choosing a TLS version greater than 1.1. means only connections with TLS 1.1 and 1.2 are accepted and TLS 1.0 is rejected. After testing to confirm your applications supports it, we recommend setting minimal TLS version to 1.2 since it includes fixes for vulnerabilities found in previous versions and is the highest version of TLS supported in Azure SQL Managed Instance.
For customers with applications that rely on older versions of TLS, we recommend setting the Minimal TLS Version per the requirements of your applications. For customers that rely on applications to connect using an unencrypted connection, we recommend not setting any Minimal TLS Version.
After setting the Minimal TLS Version, login attempts from clients that are using a TLS version lower than the Minimal TLS Version of the server will fail with following error:
Error 47072Login failed with invalid TLS version
Note
When you configure a minimum TLS version, that minimum version is enforced at the application layer. Tools that attempt to determine TLS support at the protocol layer may return TLS versions in addition to the minimum required version when run directly against the managed instance endpoint.
This article uses the Azure Az PowerShell module, which is the recommended PowerShell module for interacting with Azure. To get started with the Az PowerShell module, see Install Azure PowerShell. To learn how to migrate to the Az PowerShell module, see Migrate Azure PowerShell from AzureRM to Az.
Important
The PowerShell Azure Resource Manager module is still supported by Azure SQL Database, but all future development is for the Az.Sql module. For these cmdlets, see AzureRM.Sql. The arguments for the commands in the Az module and in the AzureRm modules are substantially identical. The following script requires the Azure PowerShell module.
The following PowerShell script shows how to Get and Set the Minimal TLS Version property at the instance level:
#Get the Minimal TLS Version property(Get-AzSqlInstance -Name sql-instance-name -ResourceGroupName resource-group).MinimalTlsVersion# Update Minimal TLS Version PropertySet-AzSqlInstance -Name sql-instance-name -ResourceGroupName resource-group -MinimalTlsVersion "1.2"
The following CLI script shows how to change the Minimal TLS Version setting in a bash shell:
# Get current setting for Minimal TLS Versionaz sql mi show -n sql-instance-name -g resource-group --query "minimalTlsVersion"# Update setting for Minimal TLS Versionaz sql mi update -n sql-instance-name -g resource-group --set minimalTlsVersion="1.2"
Regarding the policy Azure SQL Database should be running TLS version 1.2 or newer currently SQL servers are non-compliant if less than TLS version 1.2 or if the property doesn't exist at all however if TLS hasn't been set then the property on the SQL Server is "minimalTlsVersion": "None" which the BuiltIn policy doesn ...

When you create a storage account with the Azure portal, the minimum TLS version is set to 1.2 by default. To configure the minimum TLS version for an existing storage account with the Azure portal, follow these steps: Navigate to your storage account in the Azure portal. Under Settings, select Configuration.
TLS 1.3 is the latest version of the TLS protocol. TLS, which is used by HTTPS and other network protocols for encryption, is the modern version of SSL. TLS 1.3 dropped support for older, less secure cryptographic features, and it sped up TLS handshakes, among other improvements.
SQL Managed Instance has two default limits: limit on the number of subnets you can use and a limit on the number of vCores you can provision. Limits vary across the subscription types and regions. For the list of regional resource limitations by subscription type, see table from Regional resource limitation.
Architecture: Azure SQL Database is a fully managed Platform-as-a-Service (PaaS) database engine, while Azure SQL Managed Instance is a fully managed Platform-as-a-Service (PaaS) database engine that provides a native virtual network (VNet) integration.
No, the Query Store for secondary replicas feature isn't available for Azure SQL Database. Currently, the Query Store on the secondary replica contains information about workloads from the primary replica. No, the Query Store for secondary replicas feature isn't available for Azure SQL Managed Instance.
SQL Server (Beginning with SQL Server 2022 (16.x)), and Azure SQL Database support Transport Layer Security (TLS) 1.3 when TDS 8.0 is used. Even with TLS 1.3 support for TDS connections, TLS 1.2 is still required for starting up SQL Server satellite services.
SQL Server can support different TLS (Transport Layer Security) versions across various editions. The TLS versions supported by SQL Server may vary depending on the SQL Server version and the Windows operating system in use. In general, SQL Server 2008 and later versions typically support TLS 1.0, TLS 1.1, and TLS 1.2.
