While Microsoft 365 encrypts by default data stored in its cloud services both at rest and in transit, using some of the strongest and most secure encryption protocols, riks of unauthorised data access and compliance breaches remain.
To mitigate those risks, Microsoft provides an encryption implementation called Double Key Encryption (or DKE for short), which provides an enhanced level of data protection to secure sensitive documents and data. Unlike traditional encryption methods that rely on a single key, with Double Key Encryption (DKE) one key is held by Microsoft, while the other key is exclusively managed externally by the client, giving complete data sovereignty.
This implementation ensures that even if one key is compromised, the data remains encrypted and inaccessible.
With Double Key Encryption, organisation can confidently move their most sensitive data to the Azure cloud and maintain compliance with stringent data privacy regulations, including HIPAA, GDPR, FINMA, etc.
