A better secure data room option for businesses
Traditional virtual data rooms are built for billion-dollar deals and priced to match. Proton Drive is a fully end-to-end encrypted solution with secure sharing and access controls — all backed by Swiss privacy. Perfect for teams that need security without the complexity or costs.

What is a secure data room?
A secure data room is a protected online space for storing, managing, and sharing confidential and sensitive information, particularly for business acquisitions. It keeps unauthorized users from gaining access while allowing authorized users to collaborate seamlessly within a secure environment without risk of exposure.

Types of data rooms
Physical data rooms are secure in-person locations for sensitive business activities. While they still exist in highly regulated industries, most businesses have moved to virtual data rooms.
Virtual data rooms, also known as VDRs, take the same concept but bring it online. They’re purpose-built for complex, multi-party transactions such as M&A deals and come with features like Q&A modules, dynamic watermarking, granular permissions, and redaction tools. If you’re managing a sensitive multi-party deal with regulatory scrutiny, VDRs provide the necessary infrastructure, but this specialization is costly.
The simple and affordable secure data room
Not every deal needs the full infrastructure of a VDR. Proton Drive is an end-to-end encrypted file storage and sharing solution that lets you handle sensitive transactions securely, without VDR pricing.

Proton Drive keeps sensitive information protected with zero-access encryption throughout the due diligence process.

Easily set expiration dates, password-protect shared links, and revoke access the moment a transaction completes.

Protect access to key business tools by managing credentials with an end-to-end encrypted password manager.

Confidentiality is non-negotiable in legal work. Proton Drive works as a secure data room for your firm, allowing you to exchange confidential documents without worrying about unauthorized access. Granular permissions keep you in control throughout every case, allowing you to share or revoke access at any time.

Research data and patient information are highly sensitive and demand airtight security. Proton Drive is end-to-end encrypted by default, keeping all your stored files private and secure at all times. Extensive access controls enable safe sharing while supporting HIPAA compliance.
Proton Drive vs. virtual data rooms
Traditional VDRs have features designed for complex enterprise transactions and are priced to match. But more features don’t necessarily mean more value, especially if you’re paying for capabilities you’re unlikely to use. Proton Drive strikes a balance between value and security, making it the best alternative for secure data rooms.
