Tresorit
Encrypted cloud storage built for regulated business collaboration.
Tresorit is a secure cloud storage and file-sharing platform focused on end-to-end encryption, access control, and compliance-heavy collaboration. It supports business workspaces, secure client exchanges, data rooms, optional e-signatures, and data residency choices for organizations handling sensitive files.
Why it stands out
- Encrypts files on the user’s device before upload, limiting provider-side access to file contents.
- Combines secure storage, sharing, data rooms, and e-signature workflows under one vendor.
- Targets regulated sectors directly, including healthcare, finance, legal, HR, IT, and enterprise teams.
- Offers data residency options for organizations with regional sovereignty requirements.
- Provides granular sharing controls rather than treating cloud storage as simple file syncing.
Good to know
- The product is positioned mainly for businesses and regulated workflows, so it may be more than casual personal users need.
- eSign is described as an add-on rather than a core included feature.
- Compliance benefits still depend on how an organization configures access rights, sharing policies, and residency settings.
