# Microsoft 365 / Microsoft Defender ## Microsoft 365 / Microsoft Defender The Dropzone AI platform integrates with Entra ID, Exchange Online, and Microsoft Defender via the Microsoft Graph API. This document describes how to set up API credentials and install them into the Dropzone platform. ### Integration Overview To enable these integrations you will perform the following actions: * Register a new application in Microsoft Entra Admin Center * Locate your Client ID, Tenant ID, and create a Client Secret * Enable Dropzone Certificate Credentials * Assign necessary API permissions to the application * Install the credentials into your Dropzone tenant (Data Source and Alert Source) * Select integration parameters, such as which alert types to sync See the [Microsoft Integrations](https://docs.dropzone.ai/integrations/alert/ms_alert) page for instructions on how to register a new application, locate your Client ID and Tenant ID, and create a Client Secret. ## Set Application Permissions General instructions on how to assign API permissions to the application can be found in the [Microsoft Integrations](https://docs.dropzone.ai/integrations/alert/ms_alert) page. MS 365/MS Defender can utilize the following APIs: | API | Purpose | | ------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Microsoft Graph | Required for the integration to function | | Microsoft Cloud Apps Security. | Required to query investigations from Microsoft Cloud Apps. When enabled, Dropzone is able to analyze cloud apps events | | Windows Defender ATP - Live Response. | Required to extract quarantined files from Defender alerts. When enabled, Dropzone is able to independently analyze the files which will improve conclusion accuracy | | Office 365 Exchange Online Management | Required to enable Office 365 Exchange Online Management, specifically to support retrieving quarantined emails during phishing analysis | ## Microsoft Graph Permissions * In the API permissions page, click "Add a permission" * Under the Microsoft API header, select "Microsoft Graph"
