Tresorit Send

Tresorit Send is the free file-transfer companion to Tresorit's main encrypted cloud storage product. It's built around the same end-to-end encryption stack that the parent company has been selling to security-conscious enterprises since 2011.

You upload, you share a link, the recipient downloads. The encryption is genuinely zero-knowledge, meaning Tresorit can't access the file contents even if asked, which is the kind of property that matters in legal, healthcare, or journalistic workflows.

The free Send tier handles transfers up to 5GB. The main Tresorit plans get noticeably more expensive than typical cloud storage: personal plans start at $13.99/month for Essential and scale to $33.99/month for Pro.

Business plans run $18/user/month for Standard and $24/user/month for Plus billed annually, with Business Pro and Enterprise on custom quotes. That's well above the Box and OneDrive equivalents, but you're paying for Swiss data residency, the encryption guarantees, and the ability to revoke access after the fact.

For a typical podcaster sending raws to an editor, this is probably overkill, WeTransfer or TransferNow do the same job at lower friction. Where Tresorit Send becomes the right choice is when your guest is a doctor, a lawyer, or an executive with a compliance team who needs to know exactly where files were stored and who could have accessed them. In that scenario, the Swiss residency and zero-knowledge architecture earn their keep.
