[Introduction]
We're introducing the ability to display a customized message or hyperlink in the toast notification shown when an Endpoint Data Loss Prevention (DLP) policy is triggered. A toast notification is a small, temporary message that appears on the user's screen when an Endpoint DLP policy is triggered. It will include the customized hyperlink you configure. This enhancement helps organizations provide clear guidance or direct users to internal resources when a policy blocks or restricts an action.
This message is associated with Roadmap ID 526789.
[When this will happen:]
General Availability (Worldwide): Rollout will begin in late December 2025 and is expected to complete by early January 2026.
