Azure

Overview Azure Storage automatically encrypts all data at rest using Storage Service Encryption (SSE). When you specify a customer-managed key (CMK), that key is not used to encrypt the data, it is used to protect and control access to the key that encrypts the data.

In my previous article, we explored how to set up server-level Transparent Data Encryption (TDE) in Azure SQL. This method uses a single encryption key to secure multiple databases on a server or managed instance, providing consistent protection across all databases.

In Azure SQL, server-level Transparent Data Encryption (TDE) provides centralized encryption across multiple databases within a server or managed instance. By default, Azure SQL uses a Service Managed Key (SMK) for TDE, but we can also choose to deploy a Customer Managed Key (CMK) for better control.
