To track user interactions with websites for data governance and Data Loss Prevention (DLP) purposes, Microsoft Purview Endpoint DLP is the required technology. For devices using browsers such as Google Chrome or Mozilla Firefox, the Microsoft Purview extension must be deployed. This extension enables Endpoint DLP policies to monitor and control user activities, such as uploading sensitive data to generative AI websites, copying content, or printing. For Microsoft Edge, this capability is natively integrated, but the extension ensures comprehensive coverage across supported browsers on the managed devices.

B. the Microsoft Purview Information Protection client: This client is used for classifying and protecting files and emails with sensitivity labels, not for monitoring real-time user activity within a web browser.

C. the Microsoft Defender Browser Protection extension: This is a security tool designed to protect users from phishing links and malicious websites, not for data loss prevention or tracking interactions for compliance.

D. Endpoint analytics: This feature, part of Microsoft Intune, provides insights into device performance and health to improve user experience. It does not track data interactions on websites.
