Double Encryption Key (DKE)
Enhance Data Protection on Microsoft 365 with Double Key Encryption (DKE)
Duokey provides Double Key Encryption (DKE), an encryption implementation for Microsoft 365 which provides an enhanced level of encryption to secure sensitive documents and data. Unlike traditional encryption methods that rely on a single encryption key, with Double Key Encryption (DKE) one key is held by Microsoft in Azure key vault, while the other key is exclusively managed externally by the client.
DuoKey for DKE implements zero-trust access controls that filter key access based on multiple criteria including IP addresses, geographical locations, Azure Active Directory groups, individual users and device identities, while providing enhanced Multi-Party Computation (MPC) security where the customer key never exists in plain text.
With DuoKey for DKE, organisations can confidently move their most sensitive data to the Azure cloud and maintain compliance with stringent data privacy regulations, including HIPAA, GDPR, FINMA, etc.
Encrypt
There is a risk that rogue administrators working at cloud service providers access customer data or keys with the intent to misuse the data. With DuoKey you keep dual control of your encryption keys while protecting sensitive documents stored in the cloud.
Protect
The most significant threats to the exposure of sensitive or confidential data are employee mistakes. In contrast, the least significant threats to the exposure of sensitive or confidential data include government eavesdropping and lawful data requests.
Track
Check who opened your sensitive content using our DuoKey track map. We provide real-time activity logs on all sensitive content while it is decrypted using our DKE service. If you want to block access to a domain or a specific user, you can leverage on conditional access control rules.
