DSPM and shadow data: what IAM teams need to fix next

TL;DR: Data Security Posture Management is gaining traction because it finds sensitive data, maps who can reach it, and surfaces shadow data across hybrid environments, according to Netwrix and Gartner. The real governance issue is not visibility alone, but whether identity, access, and compliance controls can keep pace with data sprawl and over-permissioning.

By the numbers:

• Only 20% of organizations are expected to deploy DSPM technology by 2026.
• 72% of organizations have experienced or suspect they have experienced a breach of non-human identities.
• Systems with least-privileged AI access had a 17% incident rate vs 76% for over-privileged systems.

Questions worth separating out

Q: How should security teams use DSPM to improve least privilege in hybrid cloud environments?

A: Start by correlating discovered sensitive data with the identities, roles, and service accounts that can reach it.

Q: Why do shadow data and unmanaged repositories create governance risk?

A: Shadow data bypasses normal ownership, classification, and review processes, so nobody can confidently say who should access it or whether that access is still appropriate.

Q: How do organizations know if DSPM is actually reducing risk?

A: Look for fewer unknown repositories, fewer excessive entitlements on sensitive datasets, and shorter remediation time from discovery to access correction.

Practitioner guidance

• Map sensitive data to entitlement owners Build a repeatable inventory that links each high-value dataset to a business owner, system owner, and identity owner so access decisions have accountable reviewers.
• Prioritise shadow data remediation first Use discovery results to find unmanaged repositories such as personal drives, email attachments, and ad hoc SaaS exports, then move the highest-risk holdings into governed storage.
• Tie access reviews to data sensitivity Base recertification on the sensitivity and exposure of the data itself, not just the group or role that grants access.
