Week in brief

Defender for Cloud preview plan management brings DWU billing and migration warnings

The week’s consequential material centers on a preview Defender for Cloud path for connecting Azure environments and managing cloud security plans, with Defender Workload Unit billing and migration effects now documented. Direct onboarding is explicitly tenant-wide. Eligible Defender for Identity workspaces receive a 30-day warning before sensor v3.x activation and default Windows auditing, while Defender XDR begins a 30-day hunting-schema transition and Defender for Cloud Apps announces mid-November role-permission changes. Most remaining entries are deployment, link, terminology, or metadata maintenance.

  • New Defender for Cloud guidance says moving plan management from the Azure portal to the Defender portal changes billing to Defender Workload Units (DWUs) and shifts configuration to tenant, management-group, or subscription scope. Plans may be replaced, consolidated, or measured differently; resource-level configurations are not preserved, and migrated settings become view-only in Azure.

  • The Direct onboarding procedure now states that all eligible existing and future non-Azure servers in the same Microsoft Entra tenant are affected, including Azure Arc-connected servers. Individual-server or pilot-group selection is not supported; prerequisites include healthy Defender for Endpoint telemetry, a matching tenant, and specified roles.

  • Eligible organizations with an active Defender for Identity workspace get a banner 30 days before sensor v3.x activation and Windows auditing are enabled by default, including settings currently set to Off. Administrators are directed to select Opt out within 30 days to retain current settings.

  • The schema-change notice says `AadDeviceId` is being replaced by `EntraIdDeviceId`; `AadDeviceId` remains available for 30 days to support query updates. Hunting queries that use the old column should be revised during that transition.

  • Starting in mid-November 2026, App Governance permissions for select Microsoft Entra roles will align with Defender XDR role-based access control. The change affects Cloud App Security, Compliance Administrator, and Compliance Data Administrator roles, so role assignments should be reviewed and updated.

For Defender administrators

Prioritize cloud migration and onboarding reviews: inventory resource-level plan settings, verify intended scope and coverage, assess DWU costs, and map the full non-Azure server population before enabling Direct onboarding. Use the Identity banner’s Opt out control if current settings must be retained, update hunting queries from `AadDeviceId` within 30 days, and review App Governance role assignments before mid-November 2026.

This period briefing was generated by AI from the tracked Microsoft Learn and Message Center changes.
