Microsoft Purview is the Microsoft 365 tool for finding sensitive information in work emails and files, and then warning or blocking you if you try to share it outside the company or with someone who should not receive it. Data Loss Prevention (DLP) is a feature inside Microsoft Purview that checks work emails, files, chats, and some AI prompts for sensitive information and can stop it from being shared improperly. Microsoft Purview is preparing to apply DLP and auto-labeling to Google Workspace, Box, Dropbox, Salesforce, and other non-Microsoft platforms, but the rollout requires connectors, enterprise licensing, and additional storage charges. Earlier Purview
coverage focused on restricting external sharing in Microsoft 365.
