Prevent Saving and Sharing of Files in Any Web Browser

Stronger Encryption

Unlike other browser add-ons that use session cookies or Javascript to "lock" Web pages, FileOpen's Web Viewer encrypts Web files into OPN format with enterprise-grade AES 256-bit encryption.

Control Access

Prevent saving or download of your Web documents, prevent or limit printing, expire and revoke access, and more.

No Plug-ins or Downloads

For user environments that will not allow or tolerate installation of add-ins or plug-ins, FileOpen Web Viewer is the solution. Your users can view protected documents simply using their Web browser (must have Flash Player v.11 or higher).

Support iOS and Android Devices

Secure OPN files can also be delivered to iOS and Android devices using the FileOpen Viewer app, available on the Apple App Store and Google Play Stores.
