[Introduction]
Microsoft Purview network data security now integrates with Palo Alto Prisma Access, extending discovery and protection to network traffic. With this integration, new and existing Palo Alto Prisma Access customers can configure Microsoft Purview collection and data loss prevention policies to discover and protect sensitive data shared with unmanaged cloud apps via HTTP/HTTPS, using the same classifiers, sensitive information types, and sensitivity labels used in other Purview policies. This integration also further enriches Purview Data Security Posture Management (DSPM), Insider Risk Management (IRM), enables data security & compliance for AI interactions, and more.
