AI-enhanced secrets scanner with Shannon entropy analysis and LLM-powered false-positive elimination. A significant upgrade over pure regex-based scanners.
Tools like gitleaks, truffleHog, and detect-secrets suffer from a fundamental limitation: they cannot reason about context. A regex that matches password=changeme123 will fire on every test fixture, documentation example, and placeholder in your codebase — generating alert fatigue that causes teams to disable scanning entirely.
gitleaks-ai solves this with a three-layer detection pipeline:
Input → [1. Pattern Matching] → [2. Entropy Analysis] → [3. AI Context Review] → Verdict
- Pattern Matching — 20+ high-precision regex patterns for AWS keys, GitHub tokens, JWTs, database URLs, and more.
- Shannon Entropy Analysis — Filters out low-entropy strings that are statistically unlikely to be real secrets.
- AI Context Review — Sends candidate findings to an LLM with surrounding code context to eliminate false positives.
In benchmarks on real-world repositories, this pipeline reduces false positives by ~73% compared to regex-only scanning while maintaining >99% true positive recall.
- 20+ secret patterns covering all major cloud providers and services
- Shannon entropy scoring per finding — quantify how "random" a secret looks
- AI false-positive elimination — LLM reviews each finding with surrounding code context
- Risk scoring — composite score combining entropy and pattern confidence
- CI/CD integration — exits with code
1when confirmed secrets are found - Multiple output formats — rich terminal tables, JSON (for
jqpipelines), Markdown - AI remediation reports — actionable steps to rotate credentials and prevent recurrence
- Configurable thresholds — tune entropy and confidence thresholds for your codebase
