FileOpen Systems Inc.

FileOpen Systems Inc. specializes in rights-managed document security, offering the FileOpen Client suite—a collection of free plug-ins and viewers designed to decrypt and display PDFs, XPS files, and Microsoft Office documents that have been encrypted through the company’s server-side permission engine. Typical deployments occur inside law firms, publishers, and financial services houses that need to distribute confidential manuals, research reports, or client records while still enforcing expiry dates, print counts, watermarking, and device-specific access controls. The lightweight client integrates seamlessly with Adobe Acrobat/Reader, Microsoft Word, Excel, PowerPoint, and most major web browsers, so end-users can open protected attachments from Outlook or download encrypted titles from a subscription portal without altering established workflows. Administrators appreciate that policies travel with the file: even if a document is forwarded outside the organization, dynamic license checks against FileOpen’s cloud or on-premise rights server can instantly revoke or re-grant access. Because the software operates as a local plug-in rather than a standalone viewer, it preserves native features such as full-text search, digital signatures, and accessibility tools, ensuring that security does not degrade the reading experience. FileOpen Systems’ software is available for free on get.nero.com, with downloads delivered through trusted Windows package sources like winget, always installing the newest release and supporting batch installation of multiple applications.
