Your company uses Microsoft Defender for Endpoint.

When dealing with frequent false positives in Microsoft Defender for Endpoint alerts, such as those triggered by legitimate Office macros, the best practice is to hide false alerts while maintaining overall protection.

Microsoft Defender documenta tion prescribes the following approach:

Generate the alert (E): The alert must first appear in the queue so it can be reviewed and correctly classified.

Hide the alert (B): Analysts can hide individual alerts to clean up the queue without disabling detections or reducing coverage.

Create a suppression rule scoped to a device group (D): To prevent recurrence, suppression rules should be scoped narrowly (such as to a device group like the accounting team’s devices), maintaining the principle of least p rivilege and minimal impact.

Options A (Resolve automatically) and C (Suppress any device) would reduce visibility or broaden suppression excessively, potentially missing real threats.

This combination of actions aligns with Defender XDR’s alert management best practices , ensuring a balance between reducing noise and preserving security posture.
