Exact Data Match to support Customer Managed Key (public preview)
You will now be able to encrypt Exact Data Match (EDM) data using your own Customer Managed Key (CMK), further enhancing EDM data security.
This message is associated with Microsoft 365 Roadmap ID 70722.
When this will happen
Rollout will begin in late March and is expected to be complete by early April 2021.
How this will affect your organization
If your organization has set up CMK (currently in public preview), your EDM data will be more secure as it will be automatically encrypted using a CMK.
EDM content that is encrypted using the CMK includes the data file schemas, rule packages, and the salts, which are used in hashing the sensitive data being protected.
What you need to do to prepare
- Learn about CMK, including considerations for testing and validating during the CMK public preview: Overview of Customer Key for Microsoft 365 at the tenant level (public preview)
- Learn about EDM: Create custom sensitive information types with Exact Data Match.
