TL;DR: Modern DSPM cannot rely on a single classification layer because entity-level detection and file-level context solve different security problems, from precise sensitive-value discovery to policy decisions based on document meaning and business purpose, according to Sentra. The practical shift is toward dual-layer data governance, where context improves validation and entity signals sharpen risk scoring.
Editorial analysis by NHI Mgmt Group, based on content published by Sentra: “Entity-Level vs. File-Level Data Classification: Effective DSPM Needs Both”.
Key questions
Q: How should security teams combine entity-level and file-level classification in DSPM?
A: Use entity-level detection to find and validate sensitive values, then use file-level classification to understand the asset’s meaning and business purpose.
Q: Why do single-layer data classification models create governance risk?
A: Single-layer models either find sensitive values without context or infer context without locating actual exposure.
Q: What are the signs that DSPM classification quality is failing?
A: High alert volume, long analyst queues, frequent dismissal of findings, and growing distrust in the output are the clearest signs.
Practitioner guidance
- Implement dual-layer classification workflows Correlate entity-level findings with file-level semantics before assigning sensitivity, risk score, or policy action so one layer can validate the other.
- Validate sensitive entities before enforcement Use checksum checks, proximity logic, and validation rules for credentials, identifiers, and regulated fields before masking or redaction triggers fire.
- Map document domains to access rules Use business purpose and document type to drive domain-based access control for HR, Legal, Finance, and compliance evidence collections.
Bottom line: Modern DSPM breaks down when it treats classification as a single layer instead of a combined precision and context problem.

Dual-layer classification is the point where DSPM becomes decision-grade. A single label cannot answer both what is inside the asset and what the asset is for. Security teams need both because masking, DLP, access control, and AI governance each depend on a different truth about the same data. The practitioner conclusion is simple: classification quality should be judged by whether it improves decisions, not by how many objects it labels.
A few things that frame the scale:
- 28% of secrets incidents now originate outside code repositories, in Slack, Jira, and Confluence, and are 13% more likely to be categorised as critical than code-based leaks, according to the State of Secrets Sprawl 2026.
- 43% of security professionals are concerned about AI systems learning and reproducing sensitive information patterns from codebases, according to the State of Secrets in AppSec.
A question worth separating out:
Q: How should security teams govern sensitive data used by AI systems?
A: Security teams should treat AI as a data consumer that needs policy boundaries, not just authentication. Classify sensitive data, define which datasets may enter AI workflows, and monitor outputs, logs, and downstream reuse. If governance stops at login, the organisation can approve access while still losing control of the data itself.
