Client-End Encryption

Your data is never encrypted or unencrypted solely in the cloud; it is always done on the your device, with your own keys.

Works on Major Platforms

Our public key encryption products work on Windows, Mac, Android and iOS devices. You can now access protected files anywhere, anytime!

No File Passwords

Our key management service removes the need to remember or share file passwords with recipients.

Transparent Security

Our solutions support simple drag and drop or context menu operations, while the transparent security works to protect your files.

No IT Support Required

Clault services work out of the box, with little user configuration. Most users will be able to use it without company IT support.


Would you buy a door lock without its key? Most cloud storage services offer such 'security'. Clault users own their security keys to ensure data privacy.
