Unified MDTI APIs in Microsoft Graph Now GA

We’re thrilled to share that the unified APIs that are part of the Microsoft Graph are now generally available! These APIs come with a single endpoint, permissions, auth model, and access token. The Microsoft Defender Threat Intelligence (Defender TI) API for Incidents, Alerts, and Hunting allows organizations to query Defender TI data to operationalize intelligence gleaned from threat actors, tools, and vulnerabilities. Security teams can enrich their understanding of entities inside security incidents, automate triage efforts, and integrate with a broad ecosystem of security tools, including Microsoft Sentinel.

Use Cases:

This new Defender TI API release has many use cases, including:

Incident enrichment: This API allows you to add more context from MDTI knowledge to incident entities, which can help you better understand the incident and take appropriate action.

Advanced hunting with Azure notebook: With this API, you can perform advanced hunting using Azure notebooks, which can help you identify potential threats and take proactive measures.

SIEM integration: This API allows you to run correlation and build integration with SOAR and SIEM systems, which can help you streamline your security operations.

Reporting: This API provides the ability to build rich and custom reporting on top of the MDTI data, which can help you gain insights into your security posture and make informed decisions.
