## What it is
Certipy is a Python CLI toolkit for enumerating and abusing Active Directory Certificate Services (AD CS) misconfigurations. It detects and exploits all known ESC1-ESC17 attack paths, including certificate forgery, NTLM relay to AD CS endpoints, and certificate mapping attacks.

## Use cases
- enumerate certificate authorities and templates in active directory
- find adcs misconfigurations for privilege escalation
- forge certificates to escalate privileges in a domain
- relay ntlm authentication to adcs http endpoints
- perform shadow credentials attacks
- audit adcs security as a defender

## When to choose
- you are a pentester or red teamer assessing AD CS in a Windows domain
- you need detection and exploitation of ESC1-ESC17 vulnerabilities in one tool
- you want to request, forge, or authenticate with certificates against Active Directory

## When to avoid
- you need a defensive monitoring or hardening solution rather than an attack toolkit
- your environment does not use Active Directory Certificate Services
- you lack explicit authorization to test the target environment
