How to disable end user trust

[Tcanni99]

I am attempting to secure my PDF Viewer. I wan't to make it as safe as possible. Are there any recommendations for what else I can do?

I have made the following changes, but it seems like a user could simply go into their settings and revert my changes? How do I stop them from re-enabling or disalbing my security features?

Also, if Acrobat alerts that a PDF has macros/js, is the user still able to open the pdf if they click "Allow/Trust"? How do I take away the users ability to trust or allow pdf's? 

- Enabled Enchaned Security

- Enabled Protected Mode/View

- Disabled opening of non-PDF file attachments with external applications

- Disabled automatic rendering of PDFs in browser

- Blacklisted certain API's 

- Disabled JavaScript

- Disabled Multimedia Trust

- Blocked malicious internet connections

Hi Tcanni

We are sorry for the trouble. As described you want to make the PDF secure and wants to restrict the users from making chages to the settings.

What is the workflow/steps yuou are doing to secure the PDF file? Please refer to the steps provided in the help article https://helpx.adobe.com/in/acrobat/using/securing-pdfs-passwords.html and see if that works for you.

What is the version of the Adobe Acrobat you are using? To check the version go to Help > About Adobe Acrobat and make sure you have the latest version installed. Go to Help > Check for Updates.
