## What it is
Tailsnitch is a Go-based CLI security auditor for Tailscale configurations that scans a tailnet for 50+ misconfigurations, overly permissive access controls, and best-practice violations. It supports read-only audits and interactive remediation via the Tailscale API, with filtering by severity, category, and specific checks.

## Use cases
- audit my tailscale tailnet for security misconfigurations
- find overly permissive ACL rules in tailscale
- detect stale devices and unused auth keys in tailnet
- check if tailnet lock is enabled
- export tailscale security audit results as json
- automatically fix tailscale security issues
- verify tailscale ssh rules are not too permissive

## When to choose
- you run a Tailscale tailnet and want automated security auditing
- you need actionable, categorized findings with severity levels
- you want interactive or automated remediation of common misconfigurations

## When to avoid
- you use a different VPN or mesh networking solution
- you need continuous runtime monitoring rather than point-in-time audits
- you cannot grant API/OAuth access to your tailnet
