What is SAST?

See how What is SAST? fits local review, which evidence Code Radar produces, where coverage ends, and how trusted findings move into CI.

What SAST means here.

This guide answers what is sast directly, separates the concept from adjacent categories, and connects the decision to a practical local review workflow without overstating Code Radar coverage.

Guide

Evidence to inspect

Use “What is SAST?” as the scope for this decision: verify the input, finding detail, workflow handoff, and product boundary before you install or buy.

CriterionEvidence to inspectBoundary
Input scopeSelected files, configuration, scan mode, and enabled rules.Only included paths and configured checks are evaluated.
Finding detailFile, line, rule ID, severity, explanation, and repair direction.Illustrative output is not a result from your repository.
Workflow handoffLocal result, report format, agent context, and optional CI signal.Enable exports or CI only when the workflow needs them.
Decision fitUse the same criteria on a real repository before choosing a plan or tool.No universal winner or guaranteed outcome is claimed.

Coverage and concrete signals

SAST definitions, source patterns, data-flow boundaries, reports, and local-to-CI adoption.

  • Audience: Readers deciding whether source-level static analysis belongs in the developer workflow.
  • Evidence to inspect before you trust the result.: A concrete finding with file, line, rule, explanation, and a fix direction.
  • Boundary: SAST is not runtime testing, penetration testing, or a guarantee that an issue is exploitable.
  • Workflow: source patterns · data flow · severity · SARIF
Feature: sastChoose the next page that matches the remaining implementation or evaluation step.Feature: security scannerChoose the next page that matches the remaining implementation or evaluation step.sample-report: sample reportChoose the next page that matches the remaining implementation or evaluation step.

From local signal to shared gate.

SAST: Use the smallest workflow that proves value. Each later step should reuse evidence the team already understands. A concrete finding with file, line, rule, explanation, and a fix direction.

Apply this page’s evidence to one real repository. For “What is SAST?”, confirm which finding is produced, whether the proposed next step is reproducible, and where local scanning, reports, agents, or CI should stop or expand.
