Spot weaknesses in Active Directory before attackers do.

Active Directory (AD) holds the “keys to the kingdom,” and if not safeguarded properly, it will compromise your entire security infrastructure. Purple Knight is a free Active Directory security assessment tool built and managed by an elite group of Microsoft identity experts.

Active Directory and Azure AD is typically at the core of any organization’s security. At a basic level it is a primary mechanism for authenticating users and determining which network resources they can access. An important question here is when is the last time you audited your Active Directory? Check out podcast episode below.

Purple Knight provides valuable insight into your AD security posture. It runs as a standalone utility that queries your AD environment and performs a set of tests against many aspects of AD’s security posture, including AD Delegation, Account security, AD Infrastructure security, Group Policy security, and Kerberos security. See full list here. Purple Knight is intended to augment your security team with know-how from a community of security researchers to minimize your attack surface and stay ahead of the ever-changing threat landscape.

What’s in the report and what does it look like?

This example report summarizes the Active Directory security assessment results performed by the Semperis Purple Knight tool. The assessment performed includes querying your Active Directory environment and running a series of security indicator scripts against domains in the selected forest. This assessment represents opportunities for enhancing this Active Directory environment from a security perspective in accordance with industry best practices.
