DLP Extends Its Ability to Control Copilot Processing

A new action for the DLP Policy for Copilot allows Microsoft 365 tenants to block Copilot from performing (Bing) web searches if a prompt contains sensitive information types. The new action allows Copilot to continue to process prompts using Microsoft 365 content (if the user has a Microsoft 365 Copilot license) while stopping potentially sensitive data being sent to Bing.
