Automatic detection

iCloud is automatically detected as a storage location and added to the Boxcryptor drive. For this to work, please install the desktop application of iCloud.

End-to-end encryption

Boxcryptor encrypts your files directly on the device, therefore the data is encrypted and secured before it is moved to the storage of your choice.

Local end-to-end encryption

Boxcryptor encrypts your files directly on the computer or mobile device, meaning that the data is already protected before it gets uploaded to the cloud. The software is compatible with all major operating systems.

External certification

Boxcryptor has been audited by the independent security company Kudelski Security. The result: all security objectives are met, and the quality of the software has been verified.

Additional Security for Your iCloud

iCloud backups assist you in preventing data loss and allow you to access your data wherever you are. However, if you want to keep your data under your control and want no one but you to be able to access it, an additional security layer is necessary. Boxcryptor helps with that. Boxcryptor’s end-to-end encryption after the zero knowledge paradigm gives you full control over your files, pictures, and sensitive information. Boxcryptor protects your iCloud and gives you alone access to it on all platforms.

Seamless Integration of Boxcryptor with iCloud

When you install Boxcryptor, it creates a virtual drive and detects your iCloud automatically. In your iCloud folder in this virtual drive, you can manage all your data as you are used to. We recommend creating a new folder in the beginning, to encrypt it, and to copy all your files in there. This is the great thing about Boxcryptor: everything you add to an encrypted folder will be encrypted automatically. Encryption is on the fly which means that you will not notice the encryption when you work with your files in this drive. Boxcryptor handles everything for you in this one safe place.
