What is CloudRAID and the 100% zero-knowledge guarantee?

CloudRAID means that data stored on our servers is fragmented, the fragments are encrypted, the encrypted fragments are then redundantly distributed to 3 different storages, much like a RAID storage. If one storage gets compromised or attacked, your data is still save. It can be re-assembled by the remaining storages.

In addition to CloudRAID, the DocRAID sync tool is 100% zero-nowledge. This means we know nothing about the fragmented and encrypted data you store on our servers. This unique design means nothing leaves your computer until after it is encrypted and can not be decrypted until it is unlocked with your password on your computer. The keys are always at your site. We never have access to your keys. This goes beyond "end-to-end-encryption" it is zero-knowledge.


Your data is save with DocRAID. This is why we got awards from these international corporations and institutions:
