1. Tenant Isolation: Microsoft 365 services, including Copilot, implement tenant isolation. It means each tenant's data is logically separated from others, ensuring that one organization's data is not accessible by another.Copilot for Microsoft 365 only searches for information within the user's tenant. It cannot search for other tenants to which the user may have access, such as a tenant to whom the user is a Microsoft Entra B2B guest. The prompts that you enter into Copilot for Microsoft 365, the data they retrieve, and the generated responses all remain within the Microsoft 365 service boundary. This aligns with Microsoft's privacy, security, and compliance commitments.
2. Role-Based Access Control: Access to data within a tenant is controlled using role-based access controls, which ensure that only authorized users within an organization can access specific data sets based on their roles and permissions. Microsoft provides security tools as part of its Microsoft 365 and Azure ecosystems to help organizations enhance access control and implement the "just enough access" principle. The policies and settings defined by administrators in these tools are not only utilized by Microsoft 365 and Azure to safeguard privacy and prevent data over-sharing but also by Copilot for Microsoft 365.
3. Authorization and Authentication: Copilot uses Microsoft Entra ID for authentication and maintains strict privacy for chat data. At the start of a session, the system separates user and tenant information from chat data. Microsoft does not retain prompts or responses post-session, ensuring they aren't used to train the underlying AI models.
4. Data Access Controls: The data access in Copilot follows the same underlying controls used in other Microsoft 365 services, ensuring consistent and secure access to data across the platform. Microsoft 365 Copilot ensures that chat data is encrypted in transit and at rest. During chat sessions, data is secured with TLS 1.2+ (in transit) and AES-128 (at rest), providing high security for sensitive information.
5. Compliance with Security Standards: Implementing isolation and access controls aligns with Microsoft's commitment to security and compliance standards. Microsoft 365 Copilot is designed per GDPR principles, prioritizing user privacy and data control. It provides mechanisms for users to manage their data and comply with privacy regulations.
