ManageEngine ADAudit Plus

ManageEngine ADAudit Plus is an on-premises auditing and monitoring product for Active Directory and the surrounding server, cloud, and workstation estate. It is best for administrators who need alerts, configuration oversight, and compliance reporting in one console. The free edition is a sensible entry point for small deployments, while larger environments need to weigh the paid editions' capacity limits and annual cost.

Overview

ADAudit Plus combines directory auditing with operational monitoring rather than treating each task as a separate tool. Real-time alerts help teams react to important activity promptly, configuration monitoring keeps changes visible, and compliance reports support organisations that must document controls. Agentless monitoring can also reduce rollout work across the systems it supports.

Its on-premises deployment suits organisations that want the software kept within their own infrastructure. It is less appropriate for buyers specifically seeking a hosted service or unrestricted scale. The product comes from ManageEngine, founded in 1996 and headquartered in Pleasanton, California.

Key features

• Real-time alerts: Notifications about monitored activity are valuable where administrators need to investigate events quickly rather than rely solely on periodic reviews.
• Configuration monitoring: Watching configuration changes alongside audit events gives operations teams a clearer view of what changed and when.
• Compliance reports: Built-in reporting helps compliance-focused teams produce evidence without moving monitoring data into a separate product.
• Agentless monitoring: Avoiding endpoint agents can simplify deployment and maintenance across supported infrastructure, although coverage still depends on the listed platforms.
• Broad environment coverage: Support includes Windows Active Directory, Microsoft Entra ID, AWS Managed Microsoft AD, AD FS, Azure, AWS, GCP, Windows Server, Windows and macOS workstations, Windows file servers, Windows failover clusters, and supported NAS devices. That breadth is useful for mixed estates, not a guarantee of coverage for every appliance or directory.

Pricing

The Free edition costs 0.00 USD and is billed as a Free edition. Its allowance is 25 workstations, making it suitable for a small environment or an initial deployment, but not for a broad workstation fleet.

The Trial is 0.00 USD for a 30-day trial and permits 5 domain controllers, 2 file servers, 1 NetApp or EMC file server, 10 member servers, and 100 workstations. That is a useful capacity for evaluation, but the time limit means it is not a continuing free tier.

The Standard edition costs $595 a year as an annual subscription and lists 2 domain controllers. The Professional edition costs $945 a year, also with 2 domain controllers listed. Because both paid plans show the same domain-controller allowance, buyers should confirm which additional edition differences justify the higher Professional fee before purchase. The paid tiers are for organisations that have outgrown the free workstation cap, while the annual commitment makes them a less casual choice than the free edition.

Platforms

ADAudit Plus runs on the web and Windows, with on-premises deployment. Its monitoring scope extends across Microsoft directory services, AWS and Azure environments, GCP, Windows infrastructure, macOS workstations, and supported NAS hardware. Teams with a mixed Microsoft and cloud footprint can therefore consolidate more of their audit coverage than teams limited to a single directory.

Who it's for

This is a strong fit for IT and security administrators responsible for Active Directory who also need configuration tracking, immediate alerts, and compliance reporting. The free edition fits small deployments capped at 25 workstations; the trial is better for a short, broader proof of concept. Standard and Professional suit organisations prepared to pay annually and operate within the published domain-controller allowance.

Look elsewhere if a hosted-first architecture is essential, if workstation or controller counts exceed the plan limits, or if you want a permanently free product without capacity constraints.

Pros and cons

Pros

• One product covers several oversight jobs: Auditing, alerts, configuration monitoring, and compliance reporting reduce the need to assemble separate tools.
• Agentless approach: Monitoring can be deployed without installing agents on every supported system.
• Mixed-platform reach: Coverage spans directory services, cloud platforms, servers, workstations, and NAS devices.
• Usable free starting point: Twenty-five workstations cost nothing, and the trial provides a larger 30-day evaluation scope.

Cons

• On-premises only: Organisations wanting a fully hosted service will need a different operating model.
• Paid controller allowance: Both listed annual editions show 2 domain controllers, which may constrain larger or more distributed environments.
• Free workstation cap: The 25-workstation ceiling limits the no-cost edition to small deployments.
• Professional price justification: At $945 a year, Professional costs more than Standard while the listed controller allowance is the same.

Verdict

Choose ManageEngine ADAudit Plus if you need on-premises Active Directory auditing with real-time alerts, configuration monitoring, compliance reports, and coverage across related cloud and infrastructure platforms. Its free edition makes small deployments easy to start, but the 25-workstation cap and the 2-domain-controller allowance shown for both paid editions are the key constraints. Look elsewhere if you require hosted delivery, materially higher capacity, or a clearer distinction between paid tiers.
