ADcheck: Assess the security of your Active Directory

ADcheck

Assess the security of your Active Directory with few or all privileges. This tool offers functionalities similar to PingCastle, ORADAD, or even PurpleKnight (with some bonuses).

ADcheck is developed in pure Python to bypass operating system constraints.
