Microsoft Graph API¶
About¶
The Microsoft Graph Security API provides a unified interface and schema to integrate with security solutions from Microsoft and ecosystem partners. This empowers customers to streamline security operations and better defend against increasing cyber threats. The Microsoft Graph Security API federates queries to all onboarded security providers and aggregates responses. Use the Microsoft Graph Security API to build applications that:
- Consolidate and correlate security alerts from multiple sources
- Unlock contextual data to inform investigations
- Automate security tasks, business processes, workflows, and reporting
- Send threat indicators to Microsoft products for customized detections
- Invoke actions to in response to new threats
- Provide visibility into security data to enable proactive risk management
