SAST vs DAST

The problem this page helps clarify

The useful question is where SAST vs DAST changes the review loop: what enters the scan, who acts on a finding, and which evidence moves forward. Where SAST and DAST observe different evidence, timing, and blind spots in a delivery workflow.

• Audience: Security-minded developers comparing source analysis with runtime application testing.
• Focus: Where SAST and DAST observe different evidence, timing, and blind spots in a delivery workflow.
• Review question: What does SAST vs DAST cover in practice?

Coverage and concrete signals

For SAST vs DAST, inspect the concrete scope below instead of relying on a category label. A side-by-side decision table that separates source findings from runtime observations.

• Focus: Where SAST and DAST observe different evidence, timing, and blind spots in a delivery workflow.
• Workflow: Workflow: SAST · DAST · source code · runtime behavior
• Coverage and concrete signals: SAST, DAST, source code, runtime behavior

From local signal to shared gate.

SAST vs DAST: Use the smallest workflow that proves value. Each later step should reuse evidence the team already understands. Where SAST and DAST observe different evidence, timing, and blind spots in a delivery workflow.

Evidence to inspect before you trust the result.

SAST vs DAST: A useful result must be explainable to a developer and portable to the next review surface. Inspect the concrete evidence below before changing team policy. A side-by-side decision table that separates source findings from runtime observations.

• Workflow: SAST · DAST · source code · runtime behavior
• Exact file location, rule context, severity, confidence, and remediation guidance.
• Terminal output, SARIF, JSON, or HTML artifacts generated from the same finding set.
• Source stays in the workspace or CI runner where the scan executes.

Good fit and limits

Use SAST vs DAST when Security-minded developers comparing source analysis with runtime application testing. Keep the boundary explicit: Neither method alone covers every dependency, configuration, runtime, or business-logic risk.

Run the local proof before adopting a shared gate.

• Good fit: Security-minded developers comparing source analysis with runtime application testing.
• Not a fit / do not overreach: Neither method alone covers every dependency, configuration, runtime, or business-logic risk.

Questions to verify before rollout

These questions keep the decision tied to observable evidence rather than a broad product promise.
