Tresorit and Sealed, side by side

Disclosure. Sealed is made by Loopware LLC. We read Tresorit’s listing and its security page on 13 November 2026, made no account and did not install it. Where it is the better tool, we say so.

Built for a group, or built for one

Tresorit is a sync and sharing service. Its folders are called tresors, and you share them with friends or colleagues and manage who can do what (listing). The iPhone app is one window onto an account that also lives on your computers.

Sealed has no account and no shared space. It is one person’s vault on one phone. Sealed has no account, so there is nothing to sign up for. Backup goes to your own iCloud account, not to a server of ours. When you do send something, it goes out as a single sealed file. You can send someone an encrypted copy of an item that opens in Sealed with a passphrase you choose, and creating one is part of Sealed Pro.

Both say the company can’t read your files. The choice comes down to who else needs them.

Side by side

Where Tresorit is ahead

• Working with other people. Shared folders with permissions are the core of the product (listing). The person who receives a share needs Sealed and the passphrase, with no account and no server.
• Desk and phone. The desktop client keeps the same files on your computers (listing). Sealed runs on iPhone and iPad.
• Paperwork for companies. It holds ISO 27001:2022, audited by TÜV Rheinland, and says it works under Swiss privacy law (security). Sealed has not had an independent security audit.
• An admin who can help. In a business account, a lost password is something an admin can reset (security).

Sharing one photo, not a folder

Most people who search for a private place for photos don’t need a team space. They need to keep a set of pictures to themselves, and now and then send one to someone. A shared folder is heavy for that: the other person needs an account or a link, and the folder keeps living after the moment has passed.

Sealed sends one item as a sealed file and a passphrase you pass along another way. Sealed tells you to send the passphrase a different way from the file: in person, or through another app. The person who receives a share needs Sealed and the passphrase, with no account and no server. With Sealed Pro, the share can end on its own or be view only. An encrypted share can end after an hour, a day, 7 days or 30 days, and the receiving phone removes the item when it expires. A share of a photo, video or PDF can be view only, which leaves it no way out of the receiver’s vault. Expiring and view-only shares are part of Sealed Pro. Those limits are kept by the app on the other phone, and Sealed says plainly what they can’t do. Sealed enforces a share’s limits on the phone that receives it, and says they can’t stop a screenshot or be taken back once the share is sent.

For ways to send photos with any app, see sharing photos privately. Our page on zero-knowledge encryption explains what that promise covers, and what it leaves out.

Who should pick which

Choose Tresorit if you work with a team, need files on a computer, or want an admin to manage access (listing).

Choose a vault if the photos, scans and records are yours and stay on your phone. If you are also weighing a locked folder inside a big cloud drive, read that comparison.

Where Sealed helps, and where it doesn’t

It helps if nothing should be tied to your name or email. Sealed has no account, so there is nothing to sign up for. We run no server, so there is nothing of yours for us to see.

It helps if you send single items, not whole folders. You can send someone an encrypted copy of an item that opens in Sealed with a passphrase you choose, and creating one is part of Sealed Pro. Opening a share you received is free, but on the free plan Sealed adds photos only, and only while the vault has room.

It doesn’t offer shared folders, teams or an admin who can reset your passcode. Without the recovery key the passcode can’t be reset, not by you and not by us, and the reset screen says so.

It doesn’t keep a copy on your computer. Sealed runs on iPhone and iPad.

It doesn’t keep documents or notes on the free plan. On the free plan you can add photos. Videos, documents, notes and records need Sealed Pro.
