Tresorit is a secure content collaboration platform built to help individuals and organizations store, sync, and share sensitive information without sacrificing privacy. It brings encrypted storage, file sharing, collaboration, data rooms, and e-signatures into one product family, and is trusted by thousands of organizations worldwide. Tresorit is part of Swiss Post and positions itself as a privacy-first alternative to mainstream cloud tools for teams handling confidential files, regulated data, or client-facing work. At the core of Tresorit is zero-knowledge, end-to-end encryption. Files are encrypted on the user’s device before they are uploaded, and the encryption keys remain inaccessible to Tresorit—meaning Tresorit cannot read customer content. This architecture is designed to protect files even in scenarios where infrastructure is compromised, because plaintext data isn’t stored on Tresorit servers. Tresorit also emphasizes cryptographic design choices intended to avoid leakage through content matching or server-side visibility. For daily work, Tresorit SecureCloud provides an encrypted workspace for internal collaboration and external exchange. It supports secure file storage, syncing, and team collaboration while aiming to keep workflows simple for end users. Tresorit also offers personal and business plans, positioning personal use as an encrypted vault for sensitive documents and business use as a secure workspace that supports IT control, governance, and collaboration. Tresorit’s Drive experience lets users access encrypted content through familiar interfaces like Windows File Explorer and macOS Finder, including “cloud-only” access to avoid storing all files locally. This helps teams work efficiently while maintaining centralized control. Admins can also take action if a device is lost or compromised—for example, revoking access and unlinking the device to reduce risk. For external sharing, Tresorit FileSharing focuses on secure delivery with strong access control. Sharing links can be protected with expiration rules, passwords, watermarks, and restrictions on download or printing, with detailed activity tracking and auditing. Tresorit also integrates into email workflows like Outlook and Gmail to help reduce the risks of sending sensitive attachments, while keeping sharing secure and manageable. For structured client collaboration, Tresorit Engage provides encrypted, customizable data rooms built for ongoing projects rather than one-off transactions. It supports role-based access control, templates, document and task management, granular permissions, and branded client experiences—useful for industries like legal, finance, consulting, HR, and any scenario involving recurring confidential exchanges with external stakeholders. Tresorit extends beyond storage and sharing with Tresorit eSign, which combines document signing with encrypted file handling. It includes support for EU-qualified electronic signatures, enabling high-trust signing workflows aligned with strict legal and regulatory expectations. Tresorit also offers Tresorit Email Encryption, enabling users to send encrypted emails directly from Outlook, and provides integration options designed for organizations that need secure communication without forcing recipients into complex setups. On compliance and assurance, Tresorit highlights strong security validation and certifications. It is ISO 27001:2022 certified and has achieved Common Criteria EAL4+ certification, reflecting structured security governance and independently evaluated assurance. Tresorit also supports compliance needs such as GDPR, HIPAA (including BAA support), and other frameworks often referenced by regulated industries. For data sovereignty, it offers data residency choices across multiple regions, allowing organizations to align storage locations with legal, contractual, or internal governance requirements.
