SAST Findings Triage
What SAST findings mean and how teams validate, prioritize, disposition, and measure the recurring review workload created by static-analysis results.
Primary question: What is a SAST finding, and how should security teams validate, prioritize, and disposition large finding sets?
Direct answer
Apply a structured triage process to validate, prioritize, and disposition large volumes of SAST findings efficiently
A SAST finding is a reported potential weakness that requires contextual interpretation. Severity, validity, reachability, exploitability, and remediation priority are related but distinct properties and should not be collapsed into a single scanner label. [derscanner-sast]
Effective SAST findings triage combines severity-based prioritization, contextual analysis, and automated pre-screening to validate, prioritize, and disposition large volumes of findings efficiently. [derscanner-sast]
Triage strategy should prioritize findings based on severity, context, and organizational policy — those with higher severity, broader impact, and clearer code context — while deprioritizing findings with limited context or lower assessed relevance. [derscanner-sast]
Teams can measure the recurring operational burden of this workflow as SAST Triage Tax, reporting raw review workload, residual workload after approved automation, and queue compression separately from scanner accuracy.
Definitions
SAST finding
A reported potential security weakness with a code location, weakness classification, severity, analysis context, and trace where available. A finding is evidence for review, not automatic proof of exploitability.
SAST findings triage
The operational process of validating, prioritizing, and dispositioning a large set of findings produced by SAST tools, distinguishing confirmed findings from false positives and assigning remediation priority based on organizational policy.
Triage strategy
The approach a security team uses to organize and prioritize finding validation effort, including severity-based ordering, context-based filtering, and automated pre-screening.
SAST Triage Tax
A DerSecur-defined operational metric representing the recurring human workload required to validate, prioritize, disposition, route, and re-check SAST findings.
The engineering problem
SAST tools produce large volumes of findings, and review of each finding consumes time from AppSec teams. [derscanner-sast]
Without a structured triage strategy, security teams may spend disproportionate effort on low-priority findings while higher-priority findings remain unaddressed. [derscanner-sast]
Security controls
Each control inspects a different artifact and produces evidence for an engineering decision.
Severity-based prioritization
Finding severity ordering- Artifact
- SAST findings with severity metadata (critical, high, medium, low).
- Risk
- Low-priority findings consuming triage time while critical findings are missed.
- Output
- Ordered finding list prioritized by severity and context.
Evidence: DerScanner static analysis documentation
Automated pre-screening
AI-assisted finding evaluation- Artifact
- SAST findings evaluated by an AI system for validity and context.
- Risk
- Manual validation effort for each finding.
- Output
- AI evaluation of finding validity with reasoning, which can automatically assign `Confirmed` or `Rejected` when configured.
Evidence: DerTriage documentation
Structured validation workflow
Finding validation process- Artifact
- Validated findings with documented reasoning for each disposition decision.
- Risk
- Inconsistent validation; findings without documented reasoning.
- Output
- Documented validation results for each finding.
Evidence: DerScanner static analysis documentation
Verification workflow
- SAST tool produces findings against source code.
- Sort findings by severity and context.
- Apply automated pre-screening (AI-assisted triage) to evaluate findings for validity.
- DerTriage can automatically assign `Confirmed` or `Rejected` statuses when configured. Organizations may require human approval for selected findings, severities, or repositories.
- Confirmed findings are prioritized and assigned for remediation.
- False positives are documented and closed.
DerScanner · Enterprise
Relationship to DerScanner
DerScanner provides SAST analysis and DerTriage, which can be used together to triage large volumes of SAST findings efficiently.
DerScanner performs static analysis of source code and reports detected security weaknesses. [derscanner-sast]
DerTriage evaluates SAST detections in their broader context and returns a recommendation about detection validity with reasoning. [derscanner-dertriage]
Limits of verification
- Triage effectiveness depends on the quality of upstream SAST findings.
- DerTriage can automatically assign statuses when configured. Organizations should define which automated assignments may proceed without review and which findings require human approval.
- Severity-based prioritization does not guarantee that higher-severity findings are more exploitable.
