FileOpen
Enterprise digital rights management for secure document sharing and control
Updated February 27, 2026
FileOpen Overview
FileOpen is an enterprise-grade digital rights management (DRM) and document security platform designed to protect PDFs, Microsoft Office, and web-based files. It enables organizations to encrypt documents, enforce granular access controls, and revoke access at any time without passwords or end-user software installation.
FileOpen is widely used by publishers, enterprises, libraries, and public-sector organizations requiring scalable, policy-driven document protection.

Pros
Competitor |
Pros |
|---|---|
| Adobe LiveCycle Rights Management | Compared to Adobe LiveCycle, FileOpen is generally more cost-efficient and lighter to deploy. It avoids heavy infrastructure requirements while still supporting native PDF viewers and advanced DRM policies, making it easier for organizations that need secure distribution without committing to a large Adobe ecosystem. |
| Locklizard | FileOpen offers broader compatibility with standard PDF and Office formats, whereas Locklizard relies more heavily on proprietary viewers. This reduces friction for end-users and simplifies external sharing scenarios where recipients use different devices and operating systems. |
| Digify | While Digify focuses on simple virtual data room use cases, FileOpen provides deeper DRM controls such as dynamic watermarking, offline access rules, and controlled digital lending, making it more suitable for publishers and regulated industries. |
| Vitrium Security | FileOpen has a longer track record in large-scale publishing and library environments. Its flexible authentication methods and support for both cloud and on-premise deployments give enterprises more architectural freedom. |
| Seclore | Compared to Seclore, FileOpen is often simpler to roll out and manage, particularly for external document sharing. It emphasizes minimal end-user friction and does not require heavy client-side software installations. |
Cons
Competitor |
Cons |
|---|---|
| Adobe LiveCycle Rights Management | Compared to Adobe LiveCycle, FileOpen has fewer native integrations with the broader Adobe enterprise stack. Organizations already deeply invested in Adobe tools may find tighter workflows and reporting options within Adobe’s ecosystem. |
| Locklizard | Locklizard can offer very strict control through its proprietary viewer, while FileOpen prioritizes usability. This means FileOpen may be perceived as slightly less restrictive for organizations seeking maximum lockdown at the expense of user convenience. |
| Digify | Digify provides more transparent, self-serve pricing and a faster onboarding experience. FileOpen’s custom-quote model and enterprise focus can slow down purchasing decisions for small teams. |
| Vitrium Security | Vitrium offers more built-in analytics dashboards for content usage. FileOpen’s usage monitoring is powerful but may require more configuration and consultation to extract detailed insights. |
| Seclore | Seclore provides broader information rights management across emails and data files. FileOpen is more document-centric, which can be limiting for organizations seeking unified data protection beyond documents. |
Reviews
- apple.com Review: Multiple users report that FileOpen PDF Viewer stopped opening files after initially working for months, with one reviewer citing an “Error contacting Permission Server” on iPadOS. Support frustrates customers because it requires submitting a ticket with a promised 24-hour response that never arrives. Others call the app “Worthless” since it only opens one page at a time via a bubble selector and offers no way to scroll between pages.
- Reddit r/linuxquestions: A Linux Mint user struggles to open password-protected PDFs that rely on FileOpen, noting it only works with Adobe 7 or 8 on Linux and throws an “Unable to find the HTML rendering library (libgtkembedmoz)” error after entering the password. Attempts to locate the required library in Firefox or Thunderbird directories fail, and even printing from a Windows VirtualBox session produces an empty PDF file.
- G2 Review (Rating: 4/5): One G2 reviewer calls FileOpen RightsManager “Great software for file management and sharing,” highlighting that the education package enables easy file sharing and distribution among a large group. The ability to encrypt documents locally without uploading unencrypted files to an unknown server reinforces control over source documents.
- github.com Review: A discussion explains that FileOpen DRM relies on an Adobe proprietary coding system and only opens in Adobe-licensed software such as Adobe Reader or Acrobat 9.0 or later. Installing the FileOpen plugin alone does not guarantee access because the publisher must also grant permission, which limits compatibility with non-Adobe PDF readers.
