> Cayosoft Guardian Protector

Cayosoft Guardian Protector is a free forever, agentless hybrid change monitoring and threat detection tool that provides IT teams with real-time visibility across Active Directory, Entra ID, Microsoft 365, Teams, Intune, and Exchange Online.

As part of this release, Cayosoft has also made available a Reddit forum where users can get support for the tool. There’s also a threat directory with update-to-date information on hybrid identity attacks and detection patterns.

> ManageEngine’s 12-tool bundle

ManageEngine, makers of identity and access management software like AD Manager Plus and M365 Manager Plus, offers 12 free tools as a bundle in AD Manager Plus. These tools are designed to streamline and simplify various AD administrative tasks.

Tools include the Weak Password Users Report, Empty Password Reporter, and AD Query Tool. AD Query Tool offers an easy-to-use interface with the ability to utilize LDAP queries into user and other objects in your Active Directory (AD) environment(s).

Another useful tool, the AD Replication Manager Tool, makes manual replication events a breeze. It allows you to force replication across your domain and DCs, and view information about historical replications.

> SpecOps Command and SpecOps Password Auditor

Another powerful free AD management tool, SpecOps Command provides IT teams with a wonderful set of features for automating various tasks. A user-friendly interface assists newbies in harnessing powerful scripting languages, allowing IT Pros of all experience levels to manage users, groups, computers, and other AD objects.

The tool seamlessly integrates with AD, giving you real-time visibility into user activity records, group membership info, and other object attributes. Building efficient day-to-day tasks for your IT team is simple with Command’s library of advanced features such as change auditing, reporting, and delegation.

Highlighting security issues and optimizing the flow of daily IT Pro activities makes this a valuable tool for reducing admin overhead and improving IT overall productivity.

However, SpecOps Command is legacy product and it has been replaced with SpecOps Password Auditor, a free read-only audit tool that scans AD for password vulnerabilities.

> SolarWinds – Permission Analyzer

SolarWinds Permission Analyzer is designed to offer instant visibility into user and group permissions in AD. This free tool shows how various users’ permissions are inherited, browses permissions by group or individual users, and even analyzes permissions based on group memberships. Much more efficient than using Active Directory Users and Computers and falling down the rabbit hole of layered users and groups and all the permission layers!

The tool lets you select a user or group, then view the associated permissions. Plain and simple. It can also display a comprehensive list of permissions, including inheriting from parent objects. The built-in functionality makes it much easier to troubleshoot permission issues, audit access rights, and ensure compliance standards are adhered to.

> MaxPowerSoft Active Directory Reports Lite

MaxPowerSoft Active Directory Reports Lite is designed to provide IT teams with insights into their Active Directory environment. It offers a wide range of pre-built reports that can be customized to meet specific reporting needs.

The tool queries Active Directory objects and generates reports based on the specified criteria. Reports can be filtered, exported into common formats, and sorted. This allows IT teams to analyze user activities, group memberships, and password policies.

Value comes from providing a convenient and efficient way to gather information about AD. The tool can help identify potential security vulnerabilities and monitor user behavior.

> Netwrix Account Lockout Examiner

Netwrix Account Lockout Examiner helps IT Pros determine the causal factors behind user account lockouts. A very user-friendly interface gathers relevant event viewer records from various domain controllers, shows patterns and potential security threats, and also takes corrective action.

> Netwrix PingCastle

Another free tool bought by Netwrix is called PingCastle. This is a powerful tool to audit and assess the overall security level of your Active Directory environment. After it runs some behind-the-scenes PowerShell scripts and other commands, it generates an easy-to-read HTML dashboard to assist you in identifying discovered vulnerabilities and community-driven guidance on how to go about resolving them. This makes it an invaluable tool for IT management and operations teams, as it helps establish a common vocabulary and priorities for action plans.

PingCastle is generally updated twice a year to keep up-to-date with the latest security threats. The tool’s methodology is based on years of experience in IT and security consulting, making it a reliable and effective solution for Active Directory security assessments.

> Insight for Active Directory (Sysinternals)

Insight for Active Directory (ADInsight) collects and analyzes Active Directory data, and provides detailed information about user activities, group memberships, and object changes.

ADInsight uses DLL injection techniques to intercept calls that applications make in specific Windows libraries (DLLs). Unlike network monitor tools, ADInsight intercepts and interprets client-side APIs. It monitors any process into which it can load its tracing DLL, which means it does not require admin permissions.

> ADFind

ADFind is a very simple command-line tool developed privately by an individual that queries Active Directory. It uses ldapsearch, search.vbs, ldp, dsquery, and dsget tools with other features for good measure. This tool proceeded dsquery and dsget for years.

Your IT teams gain significant value with this free tool due to its enhanced security and operational standards. Monitoring changes in crucial AD objects makes it easy to be proactive in maintaining stability. Keeping security breaches at bay is always good measure.

> Semperis

Semperis offers a plethora of high-quality free tools designed to assist IT professionals with various Active Directory tasks. These tools provide valuable insights, automation capabilities, and security enhancements, helping companies streamline their Active Directory management and improve overall security.

I installed and performed a limited evaluation of these two tools in my Active Directory lab environment. I found both tools to be rather easy to use and very detailed in their analysis capabilities.

Free Active Directory tools can be a great starting point

Is using a free tool the right thing to do? What happens when there’s no support for it? Is it too risky to rely on a free tool for an enterprise of thousands of users? There are pros and cons to using a free tool and to spending money on a paid solution.

The core fundamental aspects you should weigh include:

• Community Support – Although you likely won’t have reliable, robust technical support with a free tool, you certainly will have community support from others using the same tools.
• Flexibility – Many free tools are open-source, allowing customization to fit your organization’s specific needs.
• Limited Features – Free AD tools will often carry a limited set of features. Paid tools undoubtedly come with more robust feature sets.
• Security Risks – Using free tools, even open-source, can open your environment to potential security risks. Paid solutions will almost always have warranties or disclosures about how they were tested and validated safe for use.

While free tools can be a great starting point, especially for smaller organizations, the lack of reliable support and potential security risks are significant drawbacks. Paid Active Directory management tools, on the other hand, offer a spectrum of robust support and advanced features, making them a better choice for larger organizations or those with critical AD management needs.
