Double Key Encryption for Microsoft 365 [Public Preview]

Double Key Encryption for Microsoft 365 [Public Preview]

Double Key Encryption enables you to protect your highly sensitive data while keeping full control of your encryption key. It uses two keys to protect your data—one key in your control, and a second key is stored securely in Microsoft Azure. Viewing data protected with Double Key Encryption requires access to both keys. Since Microsoft can access only one of these keys, your protected data remains inaccessible to Microsoft, ensuring that you have full control over its privacy and security.
