We've integrated Microsoft Secure Score into Microsoft 365 Lighthouse. This integration provides an aggregate view of the Secure Score across all managed tenants, and Secure Score details for each individual tenant. Access to Secure Score is available from a new card on the Lighthouse homepage or by selecting a tenant on the Lighthouse Tenants page.

The integration with Microsoft Lighthouse 365 is available to Microsoft partners who use the Cloud Solution Provider (CSP) program to manage customer tenants.

You can add the new permission and choose the data sources the user has access to by selecting the Security posture permissions group when creating the role. For more information, see Create custom roles with Microsoft Defender XDR Unified RBAC. Users see Secure Score data for the data sources they have permissions to.
