TresoritSend

Why It’s Useful

Tresorit Send offers a significantly more secure alternative to popular services like WeTransfer or even standard email attachments. It wins by providing true end-to-end encryption, meaning even Tresorit cannot access your files, a level of security often lacking in competitors. A lawyer needs to send confidential client documents, including contracts and personal data, to a colleague. They use Tresorit Send with a password-protected, expiring link, ensuring compliance and data security. A freelance designer needs to send a large, uncompressed video file (e.g., 3 GB) to a client for review. Tresorit Send handles the size and ensures the file is transferred securely without quality loss, and the link expires after 7 days. Tresorit Send is a completely free service, designed to showcase Tresorit's core encryption technology; there are no paid tiers for the Send service itself, though Tresorit offers paid secure cloud storage plans. The ability to set custom expiration dates (e.g., 1 day, 7 days, or 30 days) and track when a file has been downloaded provides an extra layer of control and auditability for sensitive transfers. While highly secure, its focus on simplicity means it lacks advanced features like recipient tracking beyond basic downloads, or persistent cloud storage, which some users might seek in a comprehensive file-sharing solution. As part of the Tresorit ecosystem, it benefits from the company's continuous security research and infrastructure updates, ensuring it remains at the forefront of encrypted data transfer.
