Microsoft Teams gets end-to-end encryption

- Advertisment -

Microsoft is adding end-to-end encryption support to Microsoft Teams later this year. This will be highly useful for confidential conversations between employees or for scenarios like an IT admin providing an employee their password over a call.

The initial preview will be available for 1:1 unscheduled Team calls within the first half of this year for commercial customers.

Presently, Microsoft Teams does not support end-to-end encryption for meetings.

Data is encrypted in transit and at rest, and this allows authorized services to decrypt content for data retention record purchases. Microsoft currently uses SharePoint encryption to secure at-rest files. All chat content in Teams is also encrypted in transit and at rest.

Microsoft Teams’ competitor, Slack, doesn’t use end-to-end encryption. Zoom began to implement the technology in October and is slowly adding more features to its preview.
