ITDR: Identity Threat
Detection and Response

ITDR integrates with Microsoft Sentinel by feeding identity-related threat signals directly into the SIEM platform. This allows Sentinel to correlate suspicious activity across multiple data sources, including user accounts, privileged access, and cloud applications. By leveraging AI-driven analytics, Sentinel can prioritize high-risk identity threats while automating responses such as enforcing MFA, disabling compromised accounts, or triggering custom remediation playbooks.

Microsoft Defender for Identity is designed to detect identity-based threats within Active Directory and hybrid environments, while ITDR expands on these capabilities by providing deeper behavioral analytics and automated response mechanisms. ITDR continuously monitors privileged access misuse, credential theft, and lateral movement attempts, enriching Defender for Identity alerts with contextual intelligence. This allows security teams to reduce false positives and respond to legitimate threats more effectively.

Yes, ITDR significantly strengthens Microsoft Entra ID (formerly Azure AD) by providing real-time monitoring of user identities, authentication attempts, and privilege escalations. It detects suspicious activities such as logins from unauthorized devices, impossible travel scenarios, and brute-force attacks. ITDR can then enforce conditional access policies, block high-risk sign-ins, and trigger multi-factor authentication (MFA) challenges automatically, reducing the risk of compromised accounts.

ITDR aligns with Zero Trust principles by continuously validating identity behaviors, detecting unauthorized access attempts, and enforcing least-privilege access controls. By integrating with Microsoft Sentinel, Defender for Identity, and Entra ID, ITDR ensures that only verified, risk-free users can access critical systems and data. Any deviations from normal behavior are flagged instantly, reducing insider threats and external attacks.

Yes, ITDR fully integrates with Microsoft Sentinel’s SOAR (Security Orchestration, Automation, and Response) capabilities. This means that identity-based threats detected by ITDR can trigger automated response actions such as:

• Locking compromised accounts to prevent further access.
• Revoking privileged access when suspicious privilege escalation occurs.
• Notifying SOC analysts with enriched threat intelligence for further investigation.
• Initiating remediation playbooks to contain and mitigate potential identity breaches.

This automation helps security teams respond faster to identity threats while minimizing manual effort.

ITDR enhances compliance with security frameworks and regulations such as ISO 27001, NIST, GDPR, and Cyber Essentials Plus by:

• Providing continuous monitoring of user access and authentication behaviors.
• Enforcing identity-based security policies to prevent unauthorized access.
• Generating detailed audit logs for identity-related security events.
• Automating security controls to meet compliance requirements for identity protection.

By integrating ITDR with Microsoft’s security tools, organizations can demonstrate better control over privileged access and user authentication, reducing compliance risks and potential regulatory penalties.

Yes, ITDR is designed to provide comprehensive protection for hybrid identity environments. It secures both Microsoft Entra ID (cloud identity) and traditional Active Directory (on-premises) by monitoring:

• Identity-based attack patterns (e.g., Kerberoasting, Pass-the-Hash, credential stuffing).
• Abnormal access requests targeting cloud-based resources and on-prem AD servers.
• Lateral movement and privilege escalation attempts across hybrid environments.

With full integration into Microsoft Sentinel and Defender for Identity, ITDR ensures that identity-based threats are detected and mitigated across all identity infrastructures.
