Microsoft Defender for Cloud Apps can integrate with third-party Software as a Service (SaaS) applications to enhance security by providing deeper visibility, monitoring, and control over the usage of cloud apps and data. For more information, please refer to the “Advanced Microsoft Security Services” lecture.
Microsoft Defender for Cloud Apps is a Cloud Access Security Broker (CASB), and one of its core functions is to extend security visibility and control beyond the Microsoft ecosystem to third-party Software as a Service (SaaS) applications. This integration is fundamental to its purpose of providing a comprehensive solution for protecting cloud app usage.
How Integration Enhances Security
Defender for Cloud Apps uses several methods to integrate with and secure third-party applications:
API Connectors
This is the most powerful integration method. Defender for Cloud Apps provides pre-built API connectors for popular SaaS applications like Salesforce, Box, Dropbox, ServiceNow, and Google Workspace. These connectors use the app provider’s APIs to gain deep visibility into activities, files, and accounts within the app. This allows security teams to scan for malware, apply Data Loss Prevention (DLP) policies to sensitive data, and investigate user activity logs after the fact.
Conditional Access App Control
For any web app (including third-party and custom-built ones), Defender for Cloud Apps can use a reverse proxy architecture to monitor and control user sessions in real time. When a user tries to access a configured app, their session is routed through the Defender for Cloud Apps proxy. This enables policies to be enforced during the session, such as blocking downloads of sensitive files to unmanaged devices or protecting against copy/paste actions.
Log Collection
For discovering “Shadow IT” (unapproved cloud apps used by employees), Defender for Cloud Apps analyzes traffic logs from firewalls and proxies. It uses this data to identify which cloud apps are being used, assess their risk level, and provide a score for over 31,000 apps in its catalog.
By integrating with third-party SaaS apps, Defender for Cloud Apps gives organizations a centralized way to discover app usage, protect sensitive data, detect threats from anomalous behavior, and ensure compliance across their entire cloud application landscape.
