Double Key Encryption

Protect highly sensitive data whilst remaining in full control of your encryption key

Businesses and employees across every industry are using tools like Microsoft 365 to enhance their productivity and Microsoft Purview (formerly Microsoft 365 Compliance) to safeguard and manage assets across clouds, apps, and endpoints while managing risk and regulatory compliance.

Microsoft Purview Double Key Encryption (DKE) technology - is one of the most significant developments in Microsoft Information Protection. DKE technology can be considered as the combination of Hold Your Own Key (HYOK) & Bring Your Own Key (BYOK) options for Azure Information Protocol (AIP), giving organizations complete control over their cryptographic keys and allowing them to protect their most sensitive Microsoft content whilst also meeting compliance requirements.

DKE Anchor Chart


DKE is the combination of two keys held by separate parties that encrypt or decrypt data. One key remains in the control of the customer, and the other key is stored securely in Microsoft Azure. Without access to both keys, the relevant data remains securely encrypted. As a result, the data remains secure if a key is compromised outside of the customer's control.

UTIMACO experts provide organizations with the necessary solutions in order to develop a DKE strategy, including an implementation and deployment outline.

Organizations will require UTIMACO’s HSM and UTIMACO DKE Anchor for Microsoft Purview DKE.
