Active Directory Audit Tool & AD Change Auditing Software

Active Directory auditing in Real-Time. Detect security risks, suspicious behaviour and unauthorised changes across AD Domain Controllers.

Active Directory Audit

From User Creation to Privilege Changes, Audit It All.

Active Directory Auditing & Change Tracking Tool

InfraSOS provides event-based Active Directory auditing that helps organisations track who changed what, when it happened, and where the change originated across their domain controllers.

By auditing Windows security and directory service Event IDs, InfraSOS creates a centralised audit trail of Active Directory activity, making it easier to detect risky changes, investigate incidents, and support security and compliance requirements.

Why Active Directory Auditing Matters

Active Directory remains one of the most targeted attack surfaces in enterprise environments.
Changes to users, groups, permissions, and policies can introduce significant security risk if they go unnoticed.

Active Directory auditing helps organisations:

  • Identify unauthorised or unexpected changes
  • Detect privilege escalation and admin abuse
  • Maintain an audit trail for compliance and investigations
  • Reduce time spent manually reviewing event logs
  • Set alerts on particular events to reduce threats

InfraSOS turns raw Windows Event Logs into structured, searchable Active Directory audit data.

What InfraSOS Audits in Active Directory

InfraSOS audits Active Directory by monitoring security relevant Windows Event IDs generated by domain controllers.

Each audited event records who performed the action, what object was affected, and when the change occurred.

User & Account Changes

  • User account creation and deletion
  • User account enable / disable activity
  • Admin-initiated password resets
  • Blocked or disabled account activity

Group & Privilege Changes

  • Group membership changes
  • Domain Admin and other privileged group changes
  • Security group modifications
  • Privileged access assignments
AD Audit Tool

Administrative & Security Activity

  • Administrator logons
  • Admin actions outside business hours
  • High-risk authentication events
  • Suspicious or abnormal activity patterns

Server & Directory Changes

  • System Shutdown & Reboots
  • GPO Changes
  • New process created (detecting malicious scripts)
  • Hardware & software changes
  • AD Health & replication

Windows Event Based Active Directory Change Auditing

InfraSOS uses Windows Event-ID based auditing, allowing customers to audit Active Directory changes using the same trusted data sources already built into Windows.

How it Works

  1. Domain controllers forward Windows security events to InfraSOS Windows collector on-premise
  2. InfraSOS analyses and categorises AD-related Event IDs
  3. Events are enriched with context such as user, group, and system
  4. Changes are displayed in a central audit dashboard

This approach provides accurate attribution and real-time visibility without requiring intrusive agents or complex SIEM deployments.

Custom AD Audit Alert Profiles

InfraSOS allows customers to define custom Active Directory alert profiles.

With alert profiles, users can:

  • Select which Event IDs to alert
  • Filter on event attributes (user, group, object name, OU)
  • Assign severity levels (Critical, Attention, Review)
  • Apply custom labels such as:
    • Privileged Access
    • Risky Users
    • Compliance
    • Identity Lifecycle
  • Choose alert notification behaviour (at event detection, daily summary or log in portal-only)

This ensures that critical changes are highlighted, while lower-risk activity is retained for review.

AD Alert Event Filtering

Active Directory Audit Trail & Reporting

InfraSOS maintains a centralised audit trail of Active Directory activity, allowing teams to:

  • Search and filter historical AD changes
  • Review change timelines and activity trends
  • Export audit data for investigations or compliance reviews
  • Identify abnormal spikes or unusual change behaviour
  • Schedule AD reports to email the latest Active Directory activity.

Audit data is organised by severity, category, and time, making reviews faster and more effective.

Security Focused Active Directory Auditing

Auditing and alerting

InfraSOS focuses on security relevant auditing, not just raw change logs.

Key benefits include:

  • Visibility into privileged access changes
  • Detection of admin activity outside business hours
  • Identification of suspicious or abnormal patterns
  • Support for security investigations and incident response

This makes InfraSOS suitable as an Active Directory security audit tool, not just a reporting utility.

Multi-Domain & Centralised Auditing

InfraSOS supports auditing across multiple Active Directory domains, providing:

  • A single dashboard to view all audited changes
  • Consistent auditing policies across environments
  • Easier tracking of changes in complex or hybrid setups

This is especially valuable for organisations with multiple forests or MSPs managing multiple customers.

100's of Happy IT Teams
5/5

"Instant visibility into Active Directory risks"

InfraSOS gave us immediate visibility into what was really happening inside our domain controllers. We were able to detect privileged group changes, suspicious logons, and risky user activity within minutes. The Event ID alerting is incredibly flexible and far more detailed than native Windows auditing alone. Very reponsive support team also.

"Exactly what we needed for AD and Microsoft 365 monitoring"

We were looking for a simple but powerful way to monitor Active Directory and Microsoft 365 without deploying a full SIEM. InfraSOS delivered exactly that. The real-time alerts, clear severity levels, and identity-focused monitoring make it easy to spot threats and misconfigurations before they become incidents.

"Built for identity security, not just logs"

What sets InfraSOS apart is that it’s clearly built for identity security use cases. Instead of drowning in logs, we get meaningful alerts for things like new domain admins, risky logins, and unexpected changes. Setup was straightforward, and the dashboards are easy for both security and IT teams to understand
