AssistMyTeam PDF Protector 1.0.703 Portable | 1.5 Mb
Secure and protect your PDF documents in such a way that it requires a user to type in a 'Document Open Password' or 'User Password' to view it in PDF reader software. This is the simplest way to filter out your intended recipients from malicious users. With a password, your PDF content is locked and act as a first security layer to secure your information.
Additionally, lock down your PDF documents by setting a permissions or master password and restrict printing, editing and copying content in the PDF. Your intended recipients don't need a password to open the document (unless a 'Document Open Password' or 'User Password' is enforced on that PDF). However, they do need this permissions or master password to change the restrictions you have set.
