Detailed Review
Cryptomator is a different kind of entry on this page: it is not a storage service.
It is software from Skymatic GmbH in Bonn that encrypts files and file names on your device before they are synced to a cloud, so the provider only sees ciphertext. You create a vault, and the desktop and mobile apps present it as a normal drive. Encryption uses AES-256, and the code is public under GPL-3.0, with a commercial licence for software vendors and resellers.
The practical difference from Tresorit, Internxt or Filen is that you keep your existing storage. Tresorit and Filen bundle the storage and the encryption; Cryptomator gives you only the encryption and leaves hosting to Nextcloud, kDrive or whatever you already pay for.
That makes it cheap: the desktop app and unlimited vaults are free for personal use, and full mobile access costs €29.99 once per platform. For organisations, Cryptomator Hub adds user and group management and audit logs, with a free self-hosted Community edition for 5 seats.
There are real limits. You get no storage, no web preview of files and no built-in sharing link, because the cloud provider cannot read what you store. Which cloud services work depends on the platform, and the vendor lists them per platform.
The managed Hub runs in an ISO/IEC 27001 certified EU data center, but Hub Standard pricing per seat is not shown on the server-rendered page, so it has to be checked on the website. Enterprise starts at €10,000 a year for 50 seats.
What Cryptomator does well
- Encrypts both file contents and file names with AES-256 before upload
- Open source under GPL-3.0, so the code can be inspected
- Works on top of the cloud you already use, with unlimited vaults
- Free for personal use on desktop; mobile apps are a one-time €29.99
- Managed Hub runs in an ISO/IEC 27001 certified EU data center
Where Cryptomator falls short
- Provides no storage of its own, so a separate cloud is still required
- Mobile apps are paid one-time purchases per platform
- Supported cloud services vary by platform
- Hub Standard per-seat price is not shown on the pricing page
Standout feature. It adds client-side encryption to any cloud you already pay for, instead of asking you to move your files to a new provider.
