Why these tools exist at all
An unauthorized change to a privileged group, a Group Policy Object (GPO) or a directory permission can hand an attacker broad access. An honest mistake in the same places can break authentication across the business.
Windows can already log directory changes. The Audit Directory Service Changes policy setting controls whether audit events are generated when objects in Active Directory Domain Services (AD DS) change. That subcategory triggers events when an object is modified, created, undeleted, moved or deleted. The event IDs are:
- 5136: modified
- 5137: created
- 5138: undeleted
- 5139: moved
- 5141: deleted
The category only generates events on domain controllers, and only for objects that have object-level auditing enabled. The events can show what object and property changed, who changed it, and the new value.
The raw material is there. The pain is scale. The events are scattered across domain controllers, they are cryptic, and they need correlation and retention. Third-party tools exist to turn them into searchable evidence, alerts and, in some cases, undo buttons.
What the roundup compares
Petri scored each product on these points:
- Coverage of users, groups, OUs, GPOs and permissions
- Attribution (who made the change and where it came from)
- Before-and-after values
- Real-time alerts
- Rollback or preventative controls
- Hybrid AD and Entra ID support
- Reporting and integrations
- Licensing and deployment
The seven tools at a glance

| Quest Change Auditor | Detailed forensics and object protection | Five-W evidence, plus locking down critical objects |
| Semperis DSP | Identity threat detection and response | Replication-stream monitoring and remediation |
| Netwrix Auditor | Broad auditing and compliance | AD and GPO auditing within a wider audit program |
| ManageEngine ADAudit Plus | Value and pricing transparency | Public entry pricing, many built-in reports |
| Lepide Auditor | Straightforward operational auditing | Everyday auditing with rollback and permission analysis |
| SolarWinds Access Rights Manager | Auditing and access-rights management | Change history tied to access governance |
Product-by-product notes
Cayosoft Guardian Audit & Restore
Petri says Guardian covers AD, Entra ID, Microsoft 365 and Intune. It describes rollback at the object or attribute level, without a broad restore. It uses the DirSync control to pull directory deltas. It still reads domain controller security logs to work out who made a change.
Petri lists two limitations. Attribution partly depends on those logs, and transitive membership records can't currently be rolled back.
Cayosoft's own product page backs up the hybrid pitch. The vendor says it supports multi-domain, multi-forest AD and multiple Entra ID tenants. That wording comes from a vendor page I didn't retrieve in this pass, so treat it as an advertised claim. One feature Petri highlights is custom alerts that automatically reverse changes made by anyone outside an approved-accounts list.
Quest Change Auditor for Active Directory
Petri positions this one around forensic detail. Records are normalized into who, what, when and where, including the originating workstation and before-and-after values. Petri also credits it with detecting DCSync and DCShadow and with locking down critical AD, AD LDS and GPO objects.
The catch is deployment weight. Quest uses coordinators, agents and database infrastructure. Entra ID and other workload coverage may need separate components or licences, and pricing is by quotation.
Semperis Directory Services Protector
DSP watches the AD replication stream alongside other telemetry. The pitch is that this can catch changes that evade log-based or agent-based monitoring. It is aimed at security operations teams, not compliance reporting.
Petri makes one point worth repeating. DSP's change rollback is not full forest recovery, which is a separate Semperis capability.
Netwrix Auditor
Netwrix suits shops where AD is one part of a broader Microsoft and infrastructure audit program. It records before-and-after values and offers search, alerts and compliance reports. Petri notes that behavioral analytics, risk assessment, response actions, role-based access and API availability depend on the plan, and enterprise pricing is quote-based.
ManageEngine ADAudit Plus
This is the only product in the group with public entry pricing. Petri reports that in October 2026, annual subscriptions started at US$595 for Standard and US$945 for Professional, each covering two domain controllers. Petri's earlier AD security tools roundup quotes the same figures.
Read those as starting points. Add-ons and regional charges can raise the total. Petri also warns that reliable results need correctly configured Windows audit policies and object-level auditing.
Lepide Auditor
Lepide advertises before-and-after values and rollback. Its page says deployment can be agentless or agent-based. It also says not every capability is available in agentless mode, and many customers choose agentless to keep software off domain controllers. Petri lists pricing as quote-based and tells buyers to confirm which directory, Microsoft 365 and file-system features come with their package.
SolarWinds Access Rights Manager
ARM ties AD change history to a bigger question: who has access to what. Its AD Logga component monitors changes to accounts, attributes, passwords, groups and memberships. Petri notes the product is not a specialist identity threat detection tool, and edition boundaries need careful review.
The fine print that matters most
"Rollback" is not one feature
Petri warns that restoring one attribute is not the same as recovering a directory. Some products undo a single change. Some restore deleted objects. Some need snapshots taken in advance. Full forest recovery is generally a separate product.
Ask each vendor three things:
- Which object types can be reversed?
- What must be configured before a change happens (snapshots, recycle bin, licences)?
- Does an attribute-level undo count as disaster recovery? It does not.
Native auditing is still the foundation
Several tools still lean on domain controller audit settings. Enabling Audit Directory Service Changes alone doesn't guarantee an event for every modification, because the affected object also needs an appropriate auditing entry. Petri's ManageEngine and SolarWinds notes make the same dependency point in different words.
A quick sanity check on a domain controller shows the current state of the audit policy. This command is from a monitoring guide (etcsec) and is not part of Petri's piece:
auditpol /get /category:*
If Directory Service Changes shows no auditing, any tool that relies on those events will see less than you expect.
Agentless is not a free lunch
Agentless deployment is attractive because it keeps software off domain controllers. Lepide's own FAQ admits it can mean fewer capabilities. Quest, by contrast, relies on agents. Weigh that trade-off against your change-control rules for Tier 0 servers.
Vendor claims are not measurements
Nothing in this comparison is independent testing. Quest's page claims things like faster investigations, and Cayosoft's page includes a feature-comparison table against "legacy" tools. Both are vendor marketing. Petri's own limitation notes are more useful than any scorecard.
How to run a proof of concept
Petri's closing advice is to test, and it is sound. A practical plan:
- Pick representative changes: a privileged group membership edit, a GPO setting change, a delegation or permission change, and a user attribute change.
- Make each change in a lab or controlled OU, from a known account and a known workstation.
- Check whether the tool records old and new values, the initiating account and the source.
- Check alert latency and noise. Does a routine change bury the important one?
- Test reversal only on changes the vendor says it supports, and note the prerequisites.
- Confirm retention and search against your audit period, and check scaling across all domains and forests.
- Record every extra licence, add-on or separate recovery product needed.
Bottom line
The seven products fall into rough camps:
- Hybrid visibility with rollback: Cayosoft
- Forensic depth and protection: Quest
- Identity-attack defense: Semperis
- Broad audit and compliance: Netwrix
- Price-visible auditing: ManageEngine
- Snapshot-style operational restore: Lepide
- Access governance: SolarWinds
Pick by the job you need done. Whichever you choose, keep tested AD backups. No change auditor replaces them.
