Hi,

I'm trying to an managed sql database in Azure using either a managed sql instance or cosmosdb with the postgres interface. However I would like to secure the communication towards it using mTLS since all of the communication will come from outside of Azure. What would be the best approach to accomplish this?

Azure Cosmos DB

    @David Andersson Welcome to Microsoft Q&A thanks for posting your question.

    Azure Cosmos DB for PostgreSQL doesn’t support mTLS. Our service does however enforce TLS 1.2 as the minimum version of TLS for client-database connections and allows to use TLS 1.3. Apps can also do node certificate verification for TLS connectivity.

    Regards
