Microsoft 365 / Microsoft Defender | Dropzone AI Documentation

Microsoft 365 / Microsoft Defender

This is a combined document for enabling the Dropzone AI Data Source and Alert Source for Microsoft 365 / Microsoft Defender services.

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

Set Application Permissions

General instructions on how to assign API permissions to the application can be found in the Microsoft Integrations 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
