Use the Microsoft Graph APIs for Microsoft Defender Threat Intelligence

Note

The Microsoft Graph API for Microsoft Defender Threat Intelligence requires an active Defender Threat Intelligence Portal license and API add-on license for the tenant.

Organizations conducting threat infrastructure analysis and gathering threat intelligence can use Microsoft Defender Threat Intelligence (Defender TI) to streamline triage, incident response, threat hunting, vulnerability management, and cyber threat intelligence analyst workflows. In addition, you can use the APIs exposed by Microsoft Defender Threat Intelligence on Microsoft Graph to deliver world-class threat intelligence that helps protect your organization from modern cyber threats. You can identify adversaries and their operations, accelerate detection and remediation, and enhance your security investments and workflows.

These threat intelligence APIs allow you to operationalize intelligence found within the UI. This includes finished intelligence in the forms of articles and intel profiles, machine intelligence including indicators of compromise (IoCs) and reputation verdicts, and finally, enrichment data including passive DNS, cookies, components, and trackers.

Authorization

To call the threat intelligence APIs in Microsoft Graph, your app needs to acquire an access token. For details about access tokens, see Get access tokens to call Microsoft Graph. Your app also needs the appropriate permissions. For more information, see Threat intelligence permissions.

Common use cases

The threat intelligence APIs fall into a few main categories:

  • Written details about a threat or threat actor, such as article and intelligenceProfile.
  • Properties about a host, such as hostCookie, passiveDns, or whois.

The following table lists some common use cases for the threat intelligence APIs.
