Find and fix oversharing
The objective Prevent oversharing of sensitive data in Microsoft Purview DSPM: oversharing trends, key metrics and risk patterns, a remediation plan with five actions (data risk assessments for Microsoft 365 and Fabric, a default sensitivity label, a DLP policy for Copilot, and item-level scanning), the default data risk assessment for the top 100 SharePoint sites, item-level scanning with an app registration, the Identify, Protect and Monitor actions, and Remediation actions to track the work.

WHY OVERSHARING
Copilot shows what people can already open
Copilot respects permissions. If a file is shared with everyone,
Copilot can use it in an answer to anyone.
OVERSHARED, IN DSPM
Unlabeled, contains sensitive info, and shared beyond what's needed.
Fix access first, then limit what Copilot can use.
A label alone doesn't stop Copilot. Encryption or a DLP policy for Copilot does.
ITEM LEVEL
Fix single items, right in DSPM
Remove sharing link
Close a link that
shares too widely.
Apply sensitivity label
Label the item where
it lies.
Notify
Ask the owner to
review the access.
Resolve
Mark it as handled
when it's fine.
Needs item-level scanning in a custom assessment.
SharePoint only, not OneDrive. Up to 200,000 items per location.
DATA RISK ASSESSMENTS
Identify, protect, monitor
1 IDENTIFY
Weekly results from the
default assessment, or a
custom one for chosen
sources and users.
2 PROTECT
Restrict access by label
DLP keeps Copilot away from
labeled content.
Restrict all items
Keep Copilot from finding a site.
Auto-labeling
Label what's on the site.
Retention
Delete what no one opened in 3 years.
3 MONITOR
Start a SharePoint site
access review, so the site
owner confirms who
should have access.
