Proton Drive is the secure workspace for storing sensitive data and collaborating with confidence across teams, clients, and external partners.
With full end-to-end encryption, you can share files, contracts, and business documents securely — and stay in control at all times. Set passwords, expiration dates, or revoke access instantly. Files are encrypted on your device before upload, and only you and your collaborators can access them. Even Proton can’t see your data. Each user gets 1 TB of storage, and you can scale as your organization grows. Proton Drive is developed in Switzerland by the makers of Proton Mail. We’re independent, built on privacy-first principles, and free from Big Tech surveillance, lock-in, or monetization of user data. We offer more than secure storage:
- Real-time collaboration with Proton Docs
- Granular sharing controls for external and internal access
- File recovery for peace of mind
- Cross-device access, including Windows, macOS, iOS, and Android
We also help you meet compliance requirements out of the box. Proton Drive supports:
- GDPR, HIPAA, DORA, NIS2, and ISO 27001
- Independently audited SOC 2 Type II compliance
- No complex setup or third-party integrations required.
By choosing Proton Drive, you show your clients, partners, and regulators that privacy and security are built into your workflows — not an afterthought.

SEAL
SEAL provides a service for transferring files such as documents, media, design assets, datasets, and archives through the use of temporary links. Within the web application, files are encrypted in the user's browser prior to upload, while command-line interface (CLI) encryption occurs locally. Users can configure settings like expiry dates, passwords, single-use access, download limits, or NDA requirements, as well as review a signed access log and revoke hosted access at any time. Recipients can access the shared links through their browsers without needing to create an account. Additionally, SEAL features a Telegram bot, a Mini App, a CLI, an SDK, an HTTP API, and a local standard input/output MCP server. AI agents are capable of either sharing or requesting files and sensitive information; after establishing a connection, files can be sent to a SEAL inbox, with the agent receiving a handle instead of a traditional link. The Telegram bot handles file encryption on its host device, allowing chat attachments to be processed through Telegram's system first, while its Mini App performs encryption directly on the user's device. Each individual seal allows for transfers of up to 1 GB and remains active for seven days, with one-time upgrades available to increase capacity and extend the lifetime of the seal; however, each file must not exceed a limit of 10 GB. In this way, SEAL provides a versatile and secure file-sharing solution tailored to various user needs.

SendAllFiles
SendAllFiles is a secure file transfer service developed in Switzerland, designed for both individuals and teams to send large files while maintaining control over access and decryption. The service ensures that files and their associated metadata are encrypted directly in the browser using the XChaCha20-Poly1305 encryption method before they are uploaded, guaranteeing that decryption keys remain on the client side and never come into contact with SendAllFiles servers. Recipients can easily access a private link to download files without needing to create an account, while senders have the flexibility to implement optional passwords, designate expiration dates, manage retention, limit the number of downloads, receive notifications, and oversee active links. The platform features resilient chunked uploads that can recover from interruptions, enhancing the user experience. The free plan allows for up to 3 GB of file transfers each month, while the Pro plan begins at $2 per seat per month when billed annually and offers 50 GB of monthly transfer capacity. Organizations have the added benefit of selecting their storage regions and can utilize SAML or OIDC single sign-on, along with verified-domain onboarding, custom domains, and branded portals to enhance their security and branding. Furthermore, SendAllFiles operates seamlessly in a browser and is specifically crafted for secure file transfer, rather than serving as a long-term storage or backup solution, making it an ideal choice for those who prioritize security in their file sharing needs.
