DSPM Guides
Architecture, deployment, and evaluation guidance written for practitioners who already know what DSPM is and need the implementation detail that doesn't show up in vendor pitch decks or analyst briefs. No vendor names, no marketing language — the engineering and procurement decisions underneath the category.
Use the vendor comparison tool to filter the full market, and the head-to-head comparisons once you have a shortlist. These guides are for the architecture and process decisions that apply regardless of which platform you choose.

DSPM Software: An Independent Buyer's Guide
The agentless vs. agent-based decision that determines your shortlist before any feature comparison matters, plus how DSPM differs from CSPM and what consolidation risk means for platform selection right now.
Deployment architecture
-
Architecture guide›Agentless vs. Agent-Based DSPMThe deployment model decision that constrains the entire vendor shortlist. What each architecture gets right, where each struggles, and the three requirements that actually determine which one fits.
-
Architecture guide›Hardening the Side-Scanning Trust LoopAgentless scanning requires a cross-account role with broad read access. How to constrain that role with IAM condition keys, scoped KMS policies, and an isolated inspection VPC.
-
Architecture guide›The Hidden Cloud Tax: Delta-Scanning ArchitectureFull-estate re-scans generate real compute and egress costs beyond the subscription fee. How to build an event-triggered delta-scanning pipeline that only reads what changed.
AI pipelines and identity
-
Architecture guide›Defending the Vector Boundary in RAG PipelinesClassification breaks the moment data becomes a vector embedding. How to build inline interception at the ingestion layer, before sensitive data reaches a RAG or agentic pipeline.
-
Architecture guide›Risk-Proportional Session LifetimesDSPM tools know what data is exposed. Identity tools know what credentials are active. How to wire the two together so token lifetime scales with the sensitivity of what's being accessed.
Procurement and evaluation
-
Evaluation guide›Sizing a DSPM Deployment Before the Vendor Sizes It For YouDSPM pricing is consumption-based and unit definitions vary by vendor. How to build your own workload, data-volume, and seat-count model before the first sales call.
-
Evaluation guide›How to Run a DSPM POCMost DSPM POCs test whether the platform can find sensitive data at all — every platform can. How to design a POC around the specific coverage gaps and accuracy requirements that actually differentiate vendors.
