Details

Protected View is a super-sandbox that is essentially a read-only mode. When enabled, Acrobat strictly confines the execution environment of untrusted PDF’s and the processes the PDF may invoke. Acrobat also assumes all PDFs are potentially malicious and confines processing to a restricted sandbox.

When the PDF is opened, the user is presented with the option to trust the document. When the user chooses to trust the document, all features are enabled, this action assigns trust to the document and adds the document to the users’ list of Privileged Locations.
