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.

Locklizard PDF security ensures the best DRM PDF security for your files. Your PDF documents are locked to individual user's computers and cannot be shared with others. Unlike weak and unmanageable password mechanisms (passwords have to be managed, can be forgotten, or shared with others) Locklizard PDF security uses public key technology with AES 256 bit encryption and a real-time web based licensing system. There are no PDF passwords for users to enter, manage, forget or pass on to others, and no insecure plug-ins or JavaScript for complete PDF copy protection and PDF control.
