Trusted by 10,000+ organizations worldwide

Secure file sync and sharing built for SMBs and Enterprises

Businesses around the world are facing regulations, like the GDPR or HIPAA, that require them to handle confidential data in a secure, compliant way. Their clients are demanding increasing levels of security as well, but traditional ways of sharing files over email, or accessing documents via FTP & VPN, all have security flaws. Also, the popular cloud-based EFSS solutions like such as Dropbox, Box or OneDrive only employ server-side encryption. This means that any data you store on their servers is encrypted using a master key to which the server administrators have access.

Tresorit's Enterprise File Sync & Share (EFSS) solution empowers your employees to access files anywhere and collaborate internally and externally while keeping confidential information safe and intellectual property secure. Due to zero-knowledge, end-to-end encryption technology, Tresorit cannot hand over or accidentally reveal any of your data.

Replace email attachments. Non-secure email attachments and other file sync and sharing methods can be easily replaced with Tresorit links and their added control options.

Keep control. Create download links to share large files or folders with people outside your company. Keep control by setting up download limits, expiration dates, and a password for extra protection.

Access, Share and Collaborate on Files Anywhere

Access files on mobile and tablet. Tresorit's mobile apps come with built-in end-to-end encryption. No need to bother with integrations, encryption is automatic and happens without you noticing it.

Stay safe on any device. When you upload your files to the Tresorit cloud, nothing leaves your devices unencrypted. End-to-end encryption keeps your file content private when sending or downloading files on the go.

Protect against lost devices. Add additional authentication steps, unlink the device from your account and wipe the files in case a device gets lost or stolen.
