Secure File Sharing & Document Management

Companies and Organizations Face a Digital Data Explosion. According to a Cybersecurity Ventures study, cyber‑attacks linked to document leaks are expected to cost more than $10.5 trillion per year by 2025. In this context, secure file sharing and document management becomes a strategic priority. Open‑source solutions such as LinShare and Twake‑drive offer a sovereign and transparent alternative to proprietary services.

What Is Secure File Sharing and Document Management?

File sharing consists of making files available to employees, customers, or partners while controlling access, modification, and distribution. EDM (Electronic Document Management) extends this concept with:

• Indexing and advanced search

• Version management

• Archiving compliant with legal standards
   

• Full traceability of operations

In an open‑source approach, these functions rely on open standards and publicly audited code. This guarantees:

• Transparency : the code can be inspected to detect vulnerabilities.

• Interoperability : integration with other systems (LDAP, SSO, Active Directory directories).

• Sovereignty : ability to host on a private cloud or on‑premise.
   

Key Benefits of Open‑Source Solutions for Document Management

1. Advanced Security and Compliance

   • TLS encryption and server‑side file encryption
      
   • Fine‑grained access rights management (RBAC – Role‑Based Access Control)
      
   • Complete action logging (timestamped logs, electronic signatures)
      

   • GDPR compliance: hosting inside the EU, automatic deletion of expired files

2. Flexibility and Customisation

   • Auditable code that can be modified to internal needs

   • REST/HTTPS API connectors for business‑process integration
      
   • Support for standard protocols (WebDAV, CalDAV, SFTP)
      

3. Optimised Collaboration

   • Real‑time collaborative file editing with OnlyOffice or Collabora

   • Real‑time notifications

   • Automatic change history and versioning
      

4. Cost Reduction

   • No expensive proprietary licences

   • Shared or dedicated hosting according to context
      

   • Updates driven by the open‑source community
