That’s a “dynamic watermark”.

Explore the latest advancement in information protection: Dynamic Watermarking for Word, Excel, and PowerPoint. This innovative feature helps organizations mitigate the risk of data leaks via “analog loopholes” by deterring users from photographing their screens while displaying confidential information. Delve into our recent blog post for detailed insights into this new functionality.

If you work with sensitive or confidential documents, you know how vital it is to prevent any leaks of information from these documents.

However, it’s still possible for someone to take a picture of a sensitive file on their screen or of a presentation being shared either online or in-person. (Some forms of screenshotting cannot be blocked with existing technology.) This loophole presents a simple way to bypass the protections that sensitivity labels place on a document. Dynamic watermarking can be a potent weapon in combatting these kinds of leaks.
