Opportunities**

Enhanced Collaboration Across Clouds
The new feature allows secure sharing of sensitivity-labeled files across Microsoft 365 cloud environments, facilitating better collaboration among teams that operate in different regulatory frameworks. This is particularly beneficial for organizations with international operations or those working with government contracts that require strict compliance.
   - next-steps: Identify teams that frequently collaborate across different cloud environments. Provide training on the new feature and update internal documentation to include guidelines on cross-cloud sharing.
   - roles: Compliance Officer, IT Administrator, Project Manager
   - references: https://aka.ms/Purview/CrossCloudDocs, https://www.microsoft.com/microsoft-365/roadmap?filters=&searchterms=495000

Improved Compliance Management
By enabling cross-cloud sharing with sensitivity labels, organizations can ensure that compliance requirements are met even when documents are shared across different jurisdictions. This reduces the risk of non-compliance and enhances data governance.
   - next-steps: Review current compliance policies to integrate the new sharing capabilities. Conduct a risk assessment to identify potential compliance gaps that may arise from cross-cloud sharing.
   - roles: Compliance Officer, Legal Advisor, Data Protection Officer
   - references: https://aka.ms/Purview/CrossCloudDocs, https://www.microsoft.com/microsoft-365/roadmap?filters=&searchterms=495000

Streamlined IT Administration
The requirement for admin configuration using Entra ID group controls allows for centralized management of access rights. This can lead to more efficient IT operations by reducing the administrative burden associated with managing multiple cloud environments.
   - next-steps: Develop a standardized process for configuring and managing access rights across clouds. Train IT staff on using Entra ID for group management and access control.
