## What it is
bundler-audit is a command-line tool that audits a Ruby project's Gemfile.lock for gems with known vulnerabilities using the ruby-advisory-db. It also flags insecure gem sources and can update its advisory database locally.

## Use cases
- scan Gemfile.lock for vulnerable gem versions
- check Ruby dependencies against a security advisory database
- find insecure http or git gem sources in a Bundler project
- run dependency security audits in CI without network access
- update the local ruby-advisory-db before auditing
- ignore advisories that have been manually worked around

## When to choose
- you maintain a Ruby or Rails app using Bundler and want automated CVE checks
- you need an offline-capable dependency audit step in CI
- you want a lightweight CLI rather than a hosted scanning service

## When to avoid
- your project does not use Bundler or Gemfile.lock
- you need scanning for non-Ruby ecosystems like npm or pip
- you want continuous runtime monitoring rather than point-in-time audits
