DuoKey and Securosys secure Microsoft 365 16.02.2021 10:50 Lausanne based cybersecurity startup Duokey founded by experienced entrepreneurs and cryptographers, and Securosys, a leader in cybersecurity, encryption and digital identity protection from Zurich, announced today the launch of Securosys 365, a Swiss Cloud service that encrypts Microsoft 365 office application in the Microsoft Azure Cloud. It enables enterprises and governmental services to move to the cloud while adhering to the strictest data privacy regulations. Securosys 365 encrypts the contents of customer documents stored in the Microsoft cloud using keys not available to Microsoft. The solution takes advantage of Microsoft’s new Double Key Encryption (DKE) offering. Any Microsoft 365 document that is encrypted by default with keys managed by Microsoft can now be encrypted once more with an additional key: one that is under the exclusive control of the customer and securely stored in Securosys CloudsHSM. The document can only be viewed and accessed using both keys, much like the four-eyes principle. The files remain inaccessible to any provider like Microsoft, Securosys, or DuoKey.
