LockLizard PDF Security with secure PDF DRM protection provides complete security for PDF files. It prevents unauthorized distribution of your PDF documents and controls what authorized users can do with them. Control viewing and use of your PDF documents. Stop PDF copying, sharing, modifying, screen grabbing. Control the number of views and prints or disallow printing altogether. Control when PDF documents expire (if at all) and instantly revoke them. Apply dynamic watermarks as a copying deterrent - system and user information can be dynamically displayed on a protected PDF document without you having to protect the PDF file on a per user basis. Unlike standard PDF watermarks which can be easily removed, LockLizard PDF Security watermarks are always imposed.
LockLizard PDF Security makes it simple to encrypt PDF files directly from Windows Explorer, and you distribute your protected PDF files just like any other file. A simple to use web-based administration system lets you control user access to your protected PDF documents and you can revoke access in real-time even after distribution. Integrate LockLizard PDF Security with your existing ecommerce system to provide 24x7 delivery of protected PDF documents. Multiple PDF documents can be secured and PDF DRM controls applied automatically (without manual input or user intervention) using our PDF command line protection utility.
