Sensitivity labels from Microsoft Purview Information Protection offer highly effective controls to limit access to sensitive files and to prevent users from taking inappropriate actions such as printing a document, while still allowing unhindered collaboration. However, it’s still possible for users to take pictures of sensitive information on their screen or of a presentation being shared either online or in-person, and some forms of screen-shotting cannot be blocked with existing technology. This loophole presents an easy way to bypass protections that sensitivity labels enforce on a document.
We’re excited to announce dynamic watermarking, a new feature for sensitivity labels in Word, Excel, and PowerPoint, which will both deter users from leaking sensitive information and attribute leaks if they do occur. This feature is rolling out to a public preview, with full general availability planned for later in 2024.
When an admin enables the dynamic watermarking setting for a protected sensitivity label, files with that sensitivity label will render with dynamic watermarks when opened in Word, Excel, and PowerPoint.
