Data is distributed in multiple clouds simultaneously, creating a cloud-of-clouds. All users’ data is available even if some of the clouds are down, if they lose or corrupt the data, and also in case of a ransomware attack. Some of the techniques used by Vawlt include erasure coding and Byzantine-quorum systems for both dependability and cost-effectiveness. Vawlt’s architecture takes advantage of the selected providers that have the best performance at any moment, to always deliver the best outcome.
How does Vawlt work?
At Vawlt, data is distributed in multiple clouds, simultaneously, creating a cloud-of-clouds solution. Only the data owner has access to file contents, and all the data is encrypted at the client side. Data never goes through the Vawlt server; it travels directly between the users’ machines and the storage clouds. Browse below to discover Vawlt’s key technological concepts.
Your data never goes through Vawlt’s servers – it travels directly between the users’ machines and the storage clouds. This increases scalability and decreases operational costs. Performance, availability, and security of the data plane are never compromised, even if Vawlt server is down or overloaded. Vawlt’s servers only handle users and cloud accounts, billing, and data volumes configuration.
Vawlt applies a proprietary zero-knowledge end-to-end encryption protocol to your data, assuring that only the owner has access to file contents. All data is encrypted and signed (for privacy and integrity) at client-side, and the keys are never sent to Vawlt’s servers unencrypted. Vawlt works with a combined set of state-of-the-art algorithms: Asymmetric Encryption (RSA-2048), Symmetric Encryption (AES-256), Cryptographic Hashing (SHA-256), Password Hashing (PBKDF2), Secret Sharing (Shamir’s).
As a software-only multicloud solution simple to use and manage, there’s no need for IT experts to create and configure data volumes in the cloud.
Vawlt offers data encryption all through the journey and offers protection against ransomware attacks while avoiding a cloud vendor lock-in. Also, it is an enabler for your business to be GDPR compliant.
With a pay-as-you-grow model, Vawlt is a naturally scalable system that fits your architecture and needs. By choosing the best clouds for each case, it suits your storage workload most efficiently.
