Netwrix Auditor is an IT auditing and risk visibility solution that provides detailed insight into changes, configurations, and access across critical IT systems. It enables organizations to monitor activity in Active Directory, Microsoft Entra ID, Microsoft 365, Windows Server, file servers, databases, and other core infrastructure from a centralized platform.

The solution delivers real-time alerting, searchable audit trails, risk assessment dashboards, and automated compliance reporting. Its agentless architecture collects detailed activity data without degrading system performance, helping IT and security teams investigate incidents and respond to audit requests efficiently. Netwrix Auditor strengthens Active Directory security by providing real-time visibility into logons, privilege changes, group membership modifications, Group Policy updates, and other high-risk activities. It detects suspicious behavior, alerts on abnormal access patterns, and helps identify excessive permissions and dormant accounts before they increase risk. Searchable audit trails and risk-based insights support faster investigations and help reduce the likelihood of privilege escalation and unauthorized configuration changes.

Netwrix Auditor also supports least-privilege enforcement, broader security gap analysis across identities and infrastructure, and compliance efforts across on-premises and cloud systems. When integrated with Netwrix Data Classification, it extends visibility into activity around sensitive and regulated data, helping reduce overall data exposure risk.
