Comparison

Four complementary layers.
Four different records.

Prompt guardrails evaluate requests. Identity and IAM establish who may act. DSPM maps data posture. SmartVerify records observed PostgreSQL execution and results. This matrix shows where each layer establishes evidence without treating one as a replacement for another.

Execution layer
Evidence producedA record of the prompt or request evaluated and the guardrail decision.Authentication, authorization, role, policy, and access-decision records.Inventory, classification, exposure, and posture findings for data at rest.A signed record of the PostgreSQL statement as executed, returned row count, columns read, session, and agent identity.
Enforcement pointAt the model or application request boundary.At sign-in, token issuance, and resource authorization boundaries.At the data-posture and remediation workflow layer.Inside the customer VPC on the agent-to-data path.
TimingBefore or during model and tool-request handling.When identity and access decisions are made.When posture discovery, scanning, or assessment runs.As observed PostgreSQL traffic executes and the database returns results.

Use each layer for the question it can answer

Prompt guardrails can lower the probability of a bad request. Identity and IAM govern access. DSPM establishes posture. SmartVerify bounds and records the execution consequence on observed PostgreSQL connections, with zero application code changes.

Keep identity, prompt, and posture controls for their established boundaries
Add SmartVerify for signed PostgreSQL execution records
Bring the complementary records into investigation and review workflows
