Yes, but there is a limitation. The PDF will get protected and converted into both secured formats: (1) protected PDF file and (2) secure web link. However, the file attachments do not get protected and the user will be able to access them from within Adobe Reader when the protected PDF file is sent to the user. The web viewer does not show the file attachments at all.
If the PDF attachments are an integral part of the PDF and you need them protected as well, we recommend doing one of two things:
In Vitrium, click on the Users Tab > Select the User > Under User Info tab, click on 'Set the new Password' and enter in the Password text field provided.
Once completed, click Save & Exit and the new password entered will be applied.
Note: It is your responsibility as the administrator to inform your User about the password (even the username) changes made.
For users that may have a stricter IT environment that might prevent the secured content from communicating back to Vitrium’s servers for authentication, we advise customers to connect with your user’s IT team to allow the communication between their network and Vitrium’s server at protectedpdf.com and api.protectedpdf.com at 80/443.
