Active Directory Security Auditor is a Windows-based audit tool designed to help IT teams audit and inventory Active Directory (AD) environments. It was developed by a former Microsoft Program Manager for Active Directory Security. The tool automates the generation of 100+ built-in Active Directory security audit reports, covering user accounts, computer accounts, security groups, organizational units (OUs), delegation settings, and more. Reports can be scoped to specific OUs, filtered using custom LDAP queries, and configured with depth controls. Key capabilities include: - One-button generation of AD audit reports in real time - Custom LDAP filter support for tailored queries - Export of audit results to CSV format for archival and analysis - Generation of professional-grade audit reports in PDF format - Enumeration of user accounts (state, status, last logon), computer accounts (OS, status), and security groups - Identification of accounts trusted for Unconstrained Delegation - No administrative privileges, agents, or services required to operate The tool runs on any Windows computer and does not require changes to or deep knowledge of Active Directory. It is licensed on a subscription basis (monthly, quarterly, or annual). A free version is available for download.
