Azure Cosmos DB transport layer security (TLS) 1.2 enforcement starts on 29th July 2020

Published date: 22 June, 2020

To help ensure the best level of security, Azure Cosmos DB will start enforcing TLS 1.2 on 29th July 2020, on both new accounts and existing accounts where our records show that client connections use TLS 1.2 exclusively. This means that any client request that uses a TLS version lower than 1.2 will be actively rejected on these accounts.

If you are currently using a TLS version lower than 1.2 to connect to your existing account, you will not be impacted and your application will continue to work normally. We still recommend upgrading your client connections to TLS 1.2.
