No Public Registries

✓ Guardrail Dependency Guardrails Stable Security And Compliance

dependencies.no-public-registries

Requires that no dependency resolves from a well-known public package index (npm, PyPI, Maven Central, RubyGems, NuGet). Needs no configuration — use it when every package must come through an internal registry or proxy.
