Microsoft Purview network data security now integrates with Island, extending protection to Island’s browser-based workflows at the point of user interaction. With this integration, new and existing Island customers can configure Microsoft Purview collection and data loss prevention policies to detect and protect data shared with unmanaged cloud apps through the Island Enterprise Browser, the Island Extension, and browser add ins via HTTP and HTTPS, using the same classifiers, sensitive information types, and sensitivity labels used in other Purview policies. Island provides visibility and control at the presentation layer, including typed and pasted input, file transfers, and extension activity, so data can be inspected before it ever leaves the browser. This integration further enriches Purview Data Security Posture Management (DSPM), Insider Risk Management (IRM) risk score, enables data security and compliance for AI interactions, and more.
