Our difference

Your data remains protected, even in the event of a server attack

Server encryption

Server encryption

By using server-side encryption (including KMS, HSM or BYOK), the data is first transferred in its clear-text version and is then protected with encryption by the server.

The servers therefore have access to a clear-text version of the data, which means that if compromised, the data would become vulnerable.

End-to-end encryption

End-to-end encryption

By using Seald, data is secured on the client side, before being sent to the server.

This way, neither Seald nor the cloud hosting company can decrypt the protected data, even if servers are compromised.
