Business value
With CMK, security admins get stronger control over who can access your data and how they access it. When you protect your data, you give your business a strong security posture and keep control over your data. When you implement CMK in Copilot Studio, security admins know that agents your makers develop follow your business's security practices.
Feature details
All customer data stored in Copilot Studio is encrypted at rest with strong Microsoft-managed encryption keys by default. Microsoft stores and manages the database encryption key for all your data, so you don't have to.
However, Power Platform provides an option to use customer-managed encryption key (CMK) for added data protection control. Admins can rotate or swap encryption keys on demand. They can revoke and manage their own keys to control access to your customer data at any time.
In this wave, we’re adding support for CMK in Copilot Studio. Your admins can control access to your data through Power Platform Managed Environments. Turn on CMK when you create the environment. It applies to all agents in that environment.
Admins can set up, configure, and manage CMK with Power Platform and Azure Key Vault. Power Platform only allows managed environments to enable CMK.
When you enable CMK in an environment, all Copilot Studio data is encrypted with customer keys. You can cycle, disable, and manage keys within your environment to control data access as your agents' and business needs change.
If you enable CMK in an environment before the public preview date, the environment doesn't use CMK.
