DSPM and Microsoft 365: what IAM teams need to know

TL;DR: Microsoft 365 environments expose sensitive data across mail, files, collaboration, and endpoints, so DSPM complements identity and access controls by finding where data lives and who can reach it, according to Netwrix. The governance gap is not just access, but visibility into data exposure and risky permissions that IAM programmes alone do not resolve.

Questions worth separating out

Q: How should security teams use DSPM alongside Microsoft 365 access reviews?

A: Security teams should use DSPM to identify where sensitive data lives, then combine that visibility with access reviews to judge whether permissions are justified.

Q: Why do Microsoft 365 permissions and data security need separate controls?

A: Permissions answer who can reach content, while data security answers whether the content should be reachable in the first place.

Q: What breaks when organisations rely on IAM alone in Microsoft 365?

A: What breaks is visibility into where sensitive data has spread and which permissions now expose it.

Practitioner guidance

• Map sensitive data locations before recertification Run DSPM discovery across Microsoft 365 repositories before quarterly access reviews so reviewers can see whether permissions touch regulated or business-critical content.
• Tie external sharing to data classification Require classification-aware controls for external sharing links and guest access so broadly shared files are not evaluated as generic collaboration objects.
• Review inherited permissions as a data risk signal Look for folders, sites, and workspaces where inherited access has expanded the audience for sensitive content beyond the original business intent.
