Safeguard PDF Security lets you add dynamic watermarks to PDF documents displaying user and system information. You only have to protect the PDF file once for all users (rather than a static watermark for each individual user) for it to dynamically display user details such as their name, email address, company, date/time the document was viewed and printed.
Safeguard provides strong protection of PDF files to prevent users from removing watermarks. Watermarks cannot be edited and removed.
Watermarked documents with recipient name discourage sharing of screenshots and printed copies.
