Microsoft Defender for Identity

Microsoft Defender for Identity — detecting identity-based attacks in real time

Identity Threat Detection & Investigation

Combines real-time alerts and automated investigation to quickly identify and respond to potential security incidents.

  • Real-Time Alerts provide immediate notifications of suspicious activities across the network.
  • Behavioural Analytics helps streamline investigations by identifying anomalies in user activity and authentication patterns.
  • Actionable Insights offer detailed information to quickly assess and investigate identity-related threats.

Automated Remediation & Response

Responds to threats proactively to reduce the risk of further damage or unauthorized access

  • Automated Mitigation actions, such as blocking access or enforcing multi-factor authentication, when suspicious activity is detected.
  • Instant Response minimizes the window of opportunity for attackers and prevents further escalation of threats.
  • Customized Remediation tailored to your organization's needs ensures effective threat mitigation.

Integration & Advanced Threat Detection

Seamlessly integrates with Microsoft security tools to enhance protection and detect advanced attack techniques.

  • Seamless Integration with Microsoft Defender for Endpoint, Sentinel, and Azure AD Identity Protection for a unified security approach.
  • Privilege Escalation & Lateral Movement Detection identifies attempts by attackers to escalate privileges or move laterally within the network.
  • Coordinated Defense across multiple security solutions ensures comprehensive protection and response against identity-based threats.

Benefits of Microsoft Defender for Identity

Ensure your identity management systems align with security best practices and regulatory requirements.

  • Comprehensive Protection for both cloud and on-premises Active Directory environments.
  • Proactive Threat Detection reduces the impact of identity-based attacks by identifying threats early.
  • Reduced Risk of credential theft and account takeover through continuous activity monitoring.
  • Streamlined Incident Response with automated actions and integration with other Microsoft security solutions.

Microsoft Defender for Identity FAQs

What is Microsoft Defender for Identity?

Microsoft Defender for Identity is Microsoft's identity threat detection platform, monitoring on-premises Active Directory and hybrid identity environments for credential theft, privilege escalation, lateral movement, and reconnaissance activity. It uses sensors installed on domain controllers and AD FS servers to detect attacks in real time - including Kerberoasting, DCSync, Pass-the-Hash, and Golden Ticket attacks that traditional endpoint or SIEM tools miss.

What's the difference between Defender for Identity and Microsoft Entra ID Protection?

Defender for Identity monitors on-premises Active Directory and hybrid identity environments. Microsoft Entra ID Protection (formerly Azure AD Identity Protection) monitors cloud identity in Entra ID for risk signals such as: impossible travel, anonymous IP addresses, and leaked credentials. Together, they provide end-to-end identity protection across on-premises and cloud — which is why most Australian organisations running hybrid environments need both, not one or the other.

What identity threats does Defender for Identity detect?

Defender for Identity detects the specific attack techniques threat actors use against Active Directory: Kerberoasting (extracting service account credentials), DCSync (replicating password hashes from domain controllers), Pass-the-Hash and Pass-the-Ticket (using stolen credentials without cracking them), Golden Ticket and Silver Ticket attacks, LDAP reconnaissance, brute force attempts, and unusual sign-in patterns from compromised accounts. It also flags suspicious admin activity and lateral movement between domain-joined systems.

Does Defender for Identity still make sense during a cloud migration?

For most Australian organisations in the middle of a cloud migration, yes - and often more so than after the migration completes. Hybrid identity environments (domain controllers, AD FS, synchronised identities) are one of the highest-value targets for attackers because they bridge on-premises and cloud, and traditional endpoint or cloud-only tools rarely detect the identity-layer attacks Defender for Identity is designed to catch. We deploy Defender for Identity as part of broader Active Directory and Entra ID security programs, tuning detections to your specific hybrid architecture so identity risk stays covered through the transition, not just after it.

What does a Spartans Security Defender for Identity deployment involve?

Deployment is led by senior identity security specialists, and covers sensor installation on domain controllers and AD FS servers, an initial Active Directory security assessment to establish a baseline posture, tuning detection thresholds to reduce false positives, integration with Defender for Endpoint and Sentinel for cross-signal correlation, and remediation of the misconfigurations Defender for Identity typically surfaces (excessive privileges, legacy protocols, stale accounts). Our Active Directory and Entra ID assessments are informed by years of hands-on identity security work across Australian financial services, government, and enterprise clients.
