Dependency Audit
CautionAnalyzes project dependencies for known vulnerabilities (CVEs), license compliance issues, outdated packages, and supply chain security risks.

Dependency Audit analyzes your project's dependency tree for security vulnerabilities, license issues, and supply chain risks. It goes beyond simple CVE matching to assess transitive dependencies, evaluate maintenance health, and detect potential typosquatting attacks.
How It Works
- Manifest parsing — Reads package.json, requirements.txt, Gemfile, go.mod, Cargo.toml, and their lock files
- CVE matching — Cross-references all direct and transitive dependencies against vulnerability databases (NVD, GitHub Advisory, OSV)
- License analysis — Identifies license types and flags incompatible combinations (e.g., GPL in MIT projects)
- Health assessment — Checks maintenance signals: last publish date, download counts, maintainer changes
- Supply chain checks — Detects typosquatting, install scripts, and suspicious package metadata
Best For
- Regular security audits of project dependencies
- Due diligence before adopting new open-source packages
- License compliance for commercial software projects
- CI pipeline integration for automated vulnerability gating
Ecosystem Support
Full support for npm (JavaScript), pip/Poetry (Python), Cargo (Rust), Go modules, Maven/Gradle (Java), Bundler (Ruby), NuGet (.NET), and Composer (PHP).
Use Cases
- Scan npm/pip/cargo dependencies for known CVEs
- Identify transitive dependency risks in deep dependency trees
- Check license compatibility for open-source compliance
- Detect typosquatting and suspicious package patterns
Pros & Cons
Pros
- +Deep transitive dependency analysis beyond direct dependencies
- +Combined CVE, license, and supply chain assessment
- +Covers all major package ecosystems
- +Detects typosquatting and suspicious maintainer changes
Cons
- -CVE database may lag behind zero-day disclosures
- -False positives for CVEs that don't affect the used code paths
