Description:
Reports on the Microsoft Secure Score improvement action Turn on Safe Attachments in block mode, part of Microsoft Defender for Office 365. Microsoft evaluates this control across your tenant's policies and Augmentt surfaces the result alongside your other posture checks.
Why:
Safe Attachments in block mode prevents messages with detected malware attachments from being delivered. These messages are quarantined and only admins (not regular users) can review, release, or delete them. This will also automatically block future malware attachments.
Configured: 100% of users are affected by policies that are configured securely
Not Configured: One or more applicable policies are not configured securely.
Scoring: Contributes up to 1 point to the Posture Recommendations score.
