LockLizard Safeguard PDF Security provides document rights management for PDF files. This product can seamlessly encrypt PDF documents to prohibit users from viewing, copying, sharing, modifying, saving, printing (including how many times), printing to file, PDF, or image printers, and screen-grabbing. Safeguard also lets the administrator set parameters, such as when documents expire, if documents should be revoked, if user accounts expire, and whether watermarks should be applied to viewed and/or printed documents.
