If a watermark is contained within a Word document, can DLP monitor documents containing this watermark?
There are several different types of watermarks within Microsoft Word. One type is an embedded image within the Word document. The other is a custom watermark, which is simply printed text over an image.
DLP can only match the image as an exact match. IDM is recommended as an alternative.
You can use keyword detection for custom watermarks as there is actual printed text rather than an image.
