ClevaDesk system allows you to add different watermarks to PDF files. You can add a watermark both when generating reports and when downloading already existing, previously downloaded PDF files.

One use option:
In the system there are PDF files with confidential information. When downloading such files, watermarks are automatically added to them with information about who downloaded these files and when it happened. In the future, if this file is in public access, then immediately it will be possible to determine through which channel the information leakage occurred.
