Proton Drive For Business

Proton Drive for Business is a privacy-first cloud storage and collaboration platform developed by Proton AG, designed specifically to help small and medium-sized businesses securely store, manage, and share their files and documents. At its core, the platform uses end-to-end encryption to ensure that all data is encrypted on the user's device before it ever reaches Proton's servers — meaning not even Proton itself can access customer files — making it a compelling alternative to mainstream cloud storage providers for businesses that handle sensitive or confidential information. Teams can collaborate in real time using built-in document and spreadsheet tools, share files via password-protected links or email invites with customizable expiration dates, and manage access permissions through a centralized admin dashboard that supports two-factor authentication and hardware security keys. The platform is ISO 27001 and SOC 2 Type 2 certified and supports compliance with GDPR, HIPAA, and CCPA, making it particularly well-suited for industries such as healthcare, legal, financial services, and consulting where regulatory adherence is non-negotiable. With native apps available across Windows, macOS, Linux, iOS, and Android, and features like file versioning and recovery to guard against accidental data loss, Proton Drive for Business is best suited for SMBs and independent professionals who prioritize data privacy, regulatory compliance, and secure cross-team or client-facing collaboration without sacrificing usability.
