Tresorit - Secure file sync & sharing

An application for file synchronization and sharing that employs end-to-end encryption, enabling you to store, sync, and share files both securely and conveniently.

Safeguard your images in a protected environment, jot down notes from meetings for your team, and access these documents in shared folders while on the move – confident that your files are only accessible by you and those with whom you choose to share them.

Tresorit implements integrated end-to-end encryption with zero-knowledge principles to ensure maximum security. All files are encrypted on your device prior to being uploaded to the cloud, which guarantees that no one else, including hackers, authorities, or even Tresorit’s IT staff, can read them.

FAQ

I received an invitation. What do I do?

Updated 7 years ago

Registered members can send you invitations to Tresorit in three different cases:

Adding you as a member to a tresor

Tresors are secure, encrypted folders in the cloud. If someone sends you a link to collaborate on their tresor, you must register an account to be able to edit and add new files safely. Sign up and accept the tresor invitation so that you will be able to view all shared files and folders in your application.

After you log in to your account, Tresorit will ensure that all files and the connection to your inviter is secure.

Sending you files and folders

You can view and download content sent through links without having to register and create a Tresorit account. Open the link in your browser to download files and folders. If the link is password protected, you will have to enter the right password to gain access.

Account vs. subscription - what's the difference?

Updated 5 days ago

At Tresorit, an account is your login, while a subscription is the plan you choose.

Account

Your account is created with your email address and a password, which you use to sign in to Tresorit.

An account is always required to access Tresorit.

If you don’t select a paid plan, you’ll have a free Basic account (with no subscription).

 🎓 Learn how to create a strong password.

Subscription

A subscription is the plan you select (Personal, Professional, Business, or Enterprise).

To start a subscription, enter your email address, billing details, and payment method. You’ll then receive an email asking you to verify your address and set a password, which completes your account setup.

You can use Tresorit with just an account, but you cannot use a subscription without an account.

 💡 Important: Always use the same email address for both your account and your subscription – otherwise, they won’t connect.

What is Tresorit

Updated 1 year ago

Tresorit is an online cloud storage that uses end-to-end encryption to guarantee the safety of all the data you share and store.

Your data is safe with us

We can assure you that your files cannot be modified without your knowledge, even if our system was hacked. Only you have the keys to open and share your data.

We use client-side encryption to guarantee all that. Files are secured before they leave your device and remain fully encrypted until they reach the recipient.

This means that no one (not even our developers) can access the data you store. With current technology, hacking just one file would take a lifetime.

Tresors – Your secure data vaults

Tresors are secure, encrypted parent folders to your files. Any local folder on your computer can be turned into a tresor which means the contents of that folder will be encrypted and protected in the cloud. You don’t need to change your existing folder structure – any file and folder can be synced directly, without moving them to a central location.

Things you can do with tresors:

Share with links

Invite collaborators

Sync files between your devices

Backup data in the cloud

📚 Learn how to create tresors

Syncing

Access your most recent files from all devices by syncing them to your Tresorit account. Each time you modify something on your synced local folders, the changes are uploaded online.

Synced tresors are marked with a green checkmark 

You have the option to turn on selective sync on tresors. By using this feature, only the selected subfolders will sync to Tresorit on your computer.

Sharing your content with others

With Tresorit, your files are protected even if they leave your device. You have control over who can access shared files and folders.

There are two ways to share your content. You can either invite people to collaborate or you can create a share link. Both methods are secure and easy to setup, but they have key differences.

 Inviting collaborators

If you share a tresor with other people the files will appear in their Tresorit folders as they do in yours. This option is only available for tresors and invitees need to set up a Tresorit account first before they can accept the invitation.

 Sharing with links

If you share your content using this method, anyone who has the share link can access your files, even without a Tresorit account. This is available for tresors, folders, and files.

📚 Learn how to share files and tresors with others

Access permissions

When sharing tresors, you need to define access permissions for all collaborators. You can choose between three settings: manager, editor, and viewer.

Managers can read, change and re-share files.

Editors can read and modify content.

Viewers can read files.

Tresorit plans

We offer subscription packages for both teams and individuals. All plans have a unique feature list, tailored to fit the taste of teams in all sizes and individuals alike.

Team subscriptions are equipped with an Admin Center for managing users, central billing and policies.
