Purple Knight is a standalone utility that queries the Active Directory and Azure AD environment and performs a set of tests against many aspects of Active Directory’s security posture, including AD delegation, account security, AD infrastructure security, Group Policy security, and Kerberos security. Purple Knight does not require any elevated or administrator permissions.

It is designed to give a quick snapshot of your hybrid Active Directory environment as an attacker would see it. Purple Knight does not make changes to Active Directory. Need help? Use the “Contact us” form to submit your question. Thank you for joining the Purple Knight community!

Do you know your Active Directory security vulnerabilities?

Purple Knight users report an average initial security score of 61%—a barely passing grade. But users who apply the prioritized guidance provided with the assessment can systematically close AD security gaps, reducing the attack surface by up to 45%.
