[Introduction]
We’re introducing a new opt-in feature for automatic event-auditing configuration in Microsoft Defender for Identity unified sensors (v3.x). This enhancement simplifies deployment by automatically applying the required Windows event-auditing settings on sensors, reducing manual post-deployment steps and ensuring consistent policy enforcement across all onboarded sensors.
[When this will happen:]
- General Availability (Worldwide, GCC, GCCH, and DoD): The auditing opt-in feature will be available starting early January 2026, with rollout expected to complete by mid-January 2026. Until then, it will remain disabled in the portal.
- Related auditing health alerts will also roll out gradually starting early January 2026, completing by mid-January 2026.
[How this affects your organization:]
Who is affected: Admins managing Defender for Identity unified sensors (v3.x) in Microsoft 365 tenants.
What will happen:
- A new opt-in setting will be available in both the UI and via Graph API.
- In the UI, this option will appear under Defender for Identity Settings → Advanced features.
- Once enabled, the automatic configuration feature will:
- For new sensor activations: Automatically apply all required Windows event-auditing settings during activation.
- For existing onboarded sensors: Automatically apply Windows event-auditing settings only if misconfigured and dismiss related health issues.
- After enabling the toggle, the automatic configuration process may take up to 24 hours to apply across all applicable Identity Unified sensors (v3.x).
- This feature is not enabled by default and requires admin action. No changes will occur unless admins choose to enable the feature.
Relevant auditing configurations health issues covered:
- NTLM auditing is not enabled
- Directory Services Advanced Auditing is not enabled as required
- Directory Services Object Auditing is not enabled as required
- Auditing on the Configuration container is not enabled as required
- Auditing on the ADFS container is not enabled as required
[What you can do to prepare:]
No action is required unless you choose to enable the feature.
If you plan to opt in:
- Review your unified sensor deployment strategy.
- Enable the opt-in setting via the UI or Graph API.
- Communicate the change to relevant IT and security teams.
- Update internal documentation if you track auditing configurations.
