- ADAudit Plus tracks changes to users, groups, GPOs, OUs, and computer objects in near real time, with before/after values for each change
- It also covers logon/logoff auditing, file server access auditing, and UEBA-based anomaly detection — not just AD object changes
- Built primarily for security and compliance teams that need to demonstrate change control for audits like SOX, HIPAA, PCI-DSS, or GDPR
Why Native Event Logs Aren't Enough on Their Own
Windows Server can absolutely log AD changes — turn on the right Advanced Audit Policy settings and every object modification generates an event. The problem is usability: those events are scattered across every domain controller, retention is limited by local log size, correlating a change across multiple DCs takes manual work, and the raw events themselves are often cryptic (attribute GUIDs instead of human-readable names, no consolidated before/after diff). Security and compliance teams need answers like "who disabled this user account and when" or "show me every GPO change in the last quarter" in minutes, not a multi-hour log-archaeology exercise.
Purpose-built AD auditing tools solve this by continuously collecting and normalizing those events into a searchable, reportable format — which is the entire category ADAudit Plus and its competitors below compete in.
Who It's For
Security and compliance teams at organizations with formal audit requirements (SOX, HIPAA, PCI-DSS, GDPR, ISO 27001) who need to demonstrate change control over Active Directory, plus IT teams that simply want faster incident investigation than raw Event Viewer allows — e.g., quickly tracing who made a privilege-escalating group membership change. It's less necessary for very small environments with a single AD admin and no formal compliance obligations, where native logging plus disciplined change-ticket practices may be sufficient.
How It Compares
ManageEngine ADAudit Plus
Real-time change tracking across AD, Entra ID, file servers, and Windows Server, with UEBA-based anomaly detection (unusual logon times, abnormal file access patterns) layered on top of straight change auditing. Pre-built compliance report templates for the major standards save meaningful setup time versus building custom reports from raw events. Priced and licensed to be more accessible than Netwrix or Quest for mid-size IT teams.
Netwrix Auditor
Broad auditing coverage that extends beyond AD into file servers, SQL Server, Exchange, VMware, and more from a single platform — a real advantage if you need unified auditing across a wider slice of your infrastructure, not just AD. Generally positioned at a higher price point and with more setup complexity than ADAudit Plus for teams that only need AD/file-server auditing.
Quest Change Auditor
A long-established enterprise player in this category, known for low agent overhead and deep AD/Azure AD/Exchange coverage. Tends to be enterprise-priced and enterprise-deployed — a reasonable fit for large organizations already in the Quest/One Identity ecosystem, heavier than most mid-size teams need.
Native Windows Auditing (Advanced Audit Policy + Event Log)
Free and always available — no additional license. The honest tradeoff is exactly what's described above: no consolidated cross-DC view, no before/after diffs without extra scripting, limited retention, and no built-in compliance reporting. Workable for very small environments or as a supplement to a dedicated tool, not a real substitute for one at any meaningful scale.
| Tool | Best fit | Scope beyond AD |
|---|---|---|
| ADAudit Plus | Mid-size teams needing AD + file server auditing, budget-conscious | File servers, UEBA |
| Netwrix Auditor | Need auditing across AD + SQL + VMware + more | Broad, many platforms |
| Quest Change Auditor | Large enterprise, Quest/One Identity ecosystem | AD, Azure AD, Exchange |
| Native Windows Auditing | Very small environments, no budget | None (AD only, manual) |
Bottom Line
- Need real-time AD + file server change auditing with compliance reporting, without enterprise-tier pricing? ADAudit Plus is built for that.
- Need unified auditing across AD plus SQL Server, VMware, and more? Netwrix Auditor has the broader platform coverage.
- Large enterprise already in the Quest/One Identity ecosystem? Change Auditor fits that stack.
- Very small environment, no compliance mandate, comfortable with manual log review? Native Windows auditing may be enough — for now.
