What allows customers to use their own root keys for encrypting customer data?

The concept of a Customer Key is designed to give organizations greater control over their data encryption processes. With a Customer Key, businesses can use their own root keys to encrypt customer data, allowing them to maintain ownership of their encryption keys and have full control over the data protection strategy.

This approach enhances security because it means that even cloud service providers do not have access to the encryption keys. In scenarios where organizations are required to adhere to strict compliance regulations or security standards, utilizing a Customer Key can help ensure that only authorized personnel have access to sensitive data.

Managed Key relates typically to keys that are controlled entirely by the service provider, limiting the customer's control. An Encryption Policy generally defines how data is encrypted but does not provide customers with the ability to manage their own keys. The term Global Key isn’t commonly used in this context and does not accurately describe a solution that allows customers to use their own encryption keys.
