FileOpen Systems provides a versatile set of plug-ins/clients to access documents encrypted with the FileOpen software. These include a plug-in for Adobe Acrobat and Reader, a client for Microsoft Office documents, an iPad / iPhone app. We also offer a zero-client install solution, FileOpen Viewer™.

The following free clients may be downloaded to view FileOpen-secured documents (along with the permission of the publisher), and may also be used in testing FileOpen document security solutions. You may also request a free 30-day trial to encrypt your own documents.
