London, United Kingdom – April 19, 2022 | DuoKey and Atos have recently launched a joint encryption offer—with DuoKey’s innovative Double Key Encryption feature. This new technology allows organizations using Microsoft 365 to protect their sensitive data from being accessed by Microsoft and other companies or individuals. This DKE solution provides customers with complete control over privacy and military-grade security of enterprise information assets while meeting their need for sovereignty over data, especially in the public, healthcare, and energy sectors.


With the double encryption key solution developed by DuoKey and fully supported by the Atos Trustway Proteccio Hardware Security Module (HSM), your Microsoft 365 documents’ default encryption can now be much further secured. This additional protection remains under the customers’ exclusive control and is securely stored in Trustway Proteccio HSM. Thanks to this innovative DKE, Microsoft 365 documents can only be viewed and accessed using both keys: the one from Microsoft and the one protected by Duokey and Atos. Therefore, nobody except the customer has access to sensitive data. Even better, none of the vendors involved, like Microsoft, Atos, DuoKey – or any cloud storage provider, for that matter – is allowed to access your proprietary data.


“The collaboration with the Atos Trustway team has been seamless and highly efficient. Our internal teams worked closely together to natively integrate the DuoKey solution with Atos’ Trustway Proteccio HSM. Both our solutions work perfectly well together. We are extremely proud to provide all of our customers with the ability to secure—at a very granular level—their RSA 2048 key for Double Key Encryption. And all this happens within a certified HSM NATO Secret, EU Restricted, ANSSI QR,” said Nagib Aouini, the CEO of DuoKey.


“We wanted to address the need for optimum data control expressed by many of our customers, as most organizations use Microsoft 365. We are pleased to work with DuoKey to provide a cryptographic solution that ensures complete data sovereignty for our joint customers,” added Cyril Dujardin, Global Head of Digital Security at Atos.


Duokey’s native encryption solution has been designed specifically for Microsoft 365 and meets the highest security standards requirements. Atos’ Trustway Proteccio is the only HSM that holds an enhanced qualification from the French cybersecurity agency (ANSSI) and NATO secret and EU restricted qualifications. The joint solution DuoKey + Atos is fully integrated within the Microsoft 365 office suite.
