Free Active Directory Management Tools

Active Directory still runs quietly behind countless enterprise environments, handling identities, access, policies, and authentication every day. That’s despite decades of predictions that its days were numbered.

Yet, keeping pace with its evolving capabilities and managing Active Directory isn’t always simple, and relying on default admin tools only makes it harder. Native utilities can handle routine tasks, but they don’t always cut it when you need deeper security insights, forensics, automation, or advanced reporting.

That’s where the right tools can make all the difference, especially when they come without a price tag or a quotation form attached. We’ve rounded up 12 free Active Directory management tools that go beyond the basics to simplify day-to-day administration. Let’s jump right in.

As delegated access, nested groups, and inherited permissions pile up, getting a clear picture of Active Directory permissions can become difficult. Hidden rights like WriteDACL and GenericAll can quietly expand your attack surface, while finding them often means digging through permissions across numerous AD objects.

That’s where ADACL Scanner comes in.

What ADACL Scanner does?

ADACL Scanner is a free PowerShell-based tool with a GUI that brings Active Directory permissions into clearer view. It analyzes ACLs across AD objects to help admins identify excessive or potentially dangerous access, review effective rights, and tighten permissions.

Core capabilities:

• Scans DACLs and SACLs across AD objects and linked GPOs. DACLs and SACLs across AD objects, OUs, containers, and linked GPOs.
• Filters permissions by access type, user, group, or object type.
• Checks effective permissions for selected users and security principals.
• Compares current and previous permissions to spot changes.
• Generates HTML reports and exports ACL data to CSV or Excel.
• Reports object owners, inherited permissions, and disabled inheritance.
• Highlights critical permissions with color-coded results.

Ready to uncover hidden permission risks in Active Directory? Use ADACL Scanner for easier permission auditing.

Finding essential Active Directory data, such as inactive users, empty groups, or unmanaged contacts, can mean switching between admin consoles and PowerShell scripts. Additionally, native tools often lack convenient export and scheduling capabilities, making it difficult to automate and monitor Active Directory reports.

That’s where AdminDroid Free Version can help.

In complex Active Directory environments, ACLs, user sessions, and group memberships can combine to create hidden paths to privileged access. Attackers actively look for these paths to move laterally through the domain and escalate their access.

Without a clear view of these connections, security teams can miss how a low-privileged account could potentially lead to more privileged access across the domain. BloodHound helps security teams see these connections at a glance.

How BloodHound maps your AD:

BloodHound uses graph theory to map relationships between users, groups, computers, permissions, sessions, trusts, and other identity objects. Its official collector, SharpHound CE, gathers Active Directory data and feeds it into BloodHound, where admins can visualize relationships and discover potential attack paths.

Core Capabilities:

• Collects AD data with SharpHound CE, including memberships, trusts, GPOs, OUs, sessions, and local groups.
• Reveals attack paths to Tier Zero assets and other critical resources.
• Maps Active Directory relationships across users, groups, computers, permissions, and trusts.
• Identifies abusable AD configurations involving AD CS, NTLM, delegation, and privileged access.
• Exports graph data in JSON for further analysis and integration.
• Supports Cypher queries for advanced graph-based analysis.
• Supports multiple deployment options, including Docker and platform-specific installations.

Active Directory stores a vast amount of directory data, but finding specific objects and their attributes through native LDAP tools can be complex. Switching between consoles and manually crafting LDAP queries can make directory exploration and troubleshooting time-consuming. AdminDroid LDAP Explorer is built to simplify this.

How LDAP Explorer works:

AdminDroid’s LDAP Explorer for AD is a free tool that provides a visual interface for exploring Active Directory objects. Admins can browse directory objects, inspect attributes, and analyze directory data without touching the command line or writing complex LDAP queries. Instead of manually searching or scrolling through object properties, they can simply click an object to view its attributes and details at a glance.

Core capabilities:

• Navigate Active Directory structures and objects through a tree-based directory view.
• View detailed LDAP attributes in a structured table layout.
• Export directory data in CSV, Excel, HTML, and PDF formats.
• Sort and filter Active Directory data to quickly find the information you need.
• Switch between multiple Active Directory domains.
• Navigate large datasets with built-in pagination.

Active Directory environments contain countless interconnected objects, but understanding these relationships often means piecing together information from different tools and views. While BloodHound excels at mapping complex, multi-hop attack paths, its graph-based analysis can feel overwhelming when you simply need to explore Active Directory relationships and permissions. Adalanche offers a lightweight alternative.

How Adalanche works:

Adalanche runs as a standalone executable and turns collected Active Directory data into an interactive graph. Admins can explore objects, follow their relationships, and investigate permissions and group memberships without managing a separate graph database.

Core Capabilities:

• Collects Active Directory data from Windows machines and VMware vSphere environments for broader analysis.
• Maps AD relationships across users, groups, computers, permissions, and other objects through an interactive graph.
• Analyzes ACLs and ownership to uncover elevated privileges and misconfigurations.
• Explores complex relationships using Adalanche Query Language (AQL).

Group Policy Objects (GPOs) in Active Directory play a key role in governing security, yet managing them manually can quickly become complex. Over time, GPOs can accumulate broken links, orphaned objects, permission inconsistencies, stale settings, and SYSVOL issues.

Finding and troubleshooting these issues across large Active Directory environments can be tedious with native tools. That’s where GPOZaurr comes to the rescue.

How GPOZaurr works:

GPOZaurr (Group Policy Eater) is a PowerShell module for inspecting, analyzing, and fixing issues in Active Directory Group Policy. It examines GPOs, links, permissions, files, and configurations across Active Directory and SYSVOL. Admins can use these insights to identify configuration issues, broken objects, and other Group Policy problems.

Core Capabilities:

• Analyzes GPO settings and configurations across 70+ categories with detailed charts.
• Identifies broken GPOs, broken links, empty and unlinked GPOs, and issues with SYSVOL files and NetLogon ownership.
