## What it is
cargo-deny is a Cargo plugin (cargo subcommand) for linting Rust dependency graphs. It checks crate licenses against allow/deny lists, bans or duplicates dependencies, and flags crates with known security advisories.

## Use cases
- enforce license compliance across all cargo dependencies
- check rust crates for known security advisories in CI
- ban or duplicate-detect specific crates in a rust workspace
- lint large dependency graphs in a rust project
- run dependency checks as a github action
- generate a deny.toml policy for crate sources and versions

## When to choose
- you maintain a Rust project or workspace and want automated dependency policy enforcement
- you need license auditing (SPDX) and RustSec advisory checks in CI
- you want to ban certain crates, sources, or duplicate versions

## When to avoid
- you need runtime application security testing rather than dependency linting
- your project is not Rust/Cargo based
- you need legal advice on license compliance rather than automated checks

## Facets
- artifact type: cli-tool
- maturity: active
- function: linter, security, dependency-audit, cli, ci-cd
- domain: developer-tools, security, version-control, programming-languages
- platform: rust, cli, windows
