Customer Key support for Microsoft Teams now in Public Preview!

Published Dec 18 2020 08:00 AM 14.1K Views

In September, at Microsoft Ignite, we shared that Customer Key support for Microsoft Teams would become available for public preview at the end of 2020 – we are now happy to share it’s here for public preview!


Microsoft Teams helps keep data safe by encrypting it while at rest in Microsoft data centers, starting with volume-level encryption enabled through BitLocker while service encryption ensures that content at rest is encrypted at the application layer. Customer Key is built on service encryption and provides an added layer of encryption at the application level for data-at-rest and allows you as the organization to control the encryption keys.

 

Customer Key helps you meet compliance obligations because you control the encryption keys that Microsoft 365 uses to encrypt and decrypt data, enhancing your ability to meet the demands of compliance requirements that specify key arrangements with the cloud service provider.


Already available in Exchange Online, SharePoint Online, and OneDrive, this extension into Teams will be offered as a preview. You can now assign a single data encryption policy at the tenant level to encrypt your data-at-rest in Teams and Exchange. For more details, please see Overview of Customer Key for Microsoft 365 at the tenant level.

Great security add looking forward to testing it out in the new year!

I am excited about it. Unfortunately, our security thinks it's just a sham as long as Microsoft still has an availability key. I don't find anything related to HYOK in the Customer Key documentation.

Does this encryption includes also teams chat & conversation?

Correct: Service encryption with Customer Key - Microsoft 365 Compliance | Microsoft Docs

 

  • Teams chat messages (1:1 chats, group chats, meeting chats and channel conversations)

Best, Chris
