Proton Drive for Business is a secure cloud storage and collaboration solution that helps small and medium-sized businesses (SMBs) store, share, and manage files and documents with built-in privacy and security protections. It is designed to protect business data using strong encryption, support compliance with data-protection regulations, and provide remote access across devices without exposing file contents to unauthorized parties, including the service provider itself. Proton Drive for Business is especially relevant for SMBs that need to safeguard client information, intellectual property, and operational documents while enabling team collaboration and secure file distribution. Its use cases typically include securely storing business files, sharing them with internal teams or with clients and partners, editing documents and spreadsheets in real time, and managing access and compliance controls from a central admin interface. Key Features & Business-Relevant Capabilities - End-to-end encrypted cloud storage: Files are encrypted on the user’s device before upload and remain protected such that only authorized users can access them; Proton cannot decrypt customer files. - Regulatory compliance support: Designed to help meet international standards such as ISO 27001, GDPR (important for EU/Swiss SMBs), HIPAA, and CCPA through built-in security and access controls. - Swiss legal protections: Data stored under strict Swiss privacy laws, which can offer stronger protections against surveillance and data access demands compared with some other jurisdictions. - Cross-device access and productivity tools: Apps for Windows, macOS, Android, and iOS allow access and management from multiple devices, and built-in editors like Proton Docs and Proton Sheets support document and spreadsheet collaboration. Collaboration & Sharing Features - Flexible secure sharing: Share files via encrypted links or email invites, with options to set passwords, expiration dates, and to revoke access at any time. - Real-time team collaboration: Synchronized updates and built-in productivity tools help dispersed teams work together on documents and spreadsheets; changes are reflected instantly across users. - File versioning and recovery: Track changes and recover previous versions of files, which supports business continuity and reduces risk from accidental changes or data loss. Admin & Security Controls for SMBs - Central administrative panel: IT or business owners can manage users, permissions, storage limits, and monitor sharing activity from one dashboard. - Multi-user support and security policies: Enable two-factor authentication (2FA), enforce hardware security keys, and control session access to support internal security policies. Proton Drive for Business positions itself as a privacy-centric alternative to mainstream cloud services by limiting access to business data to authorized parties only and integrating compliance features that matter for SMBs operating in regulated environments.
