DISTRIBUTED STORAGE

With Vawlt, data is distributed in multiple clouds, simultaneously, creating a cloud-of-clouds.
Your data is available even if some of the clouds are down, if they lose or corrupt the data, and also if they are hacked.
Techniques like erasure coding and Byzantine-quorum systems are used for both dependability and cost-effectiveness.

DATA-CENTRIC ARCHITECTURE

Your data never goes through Vawlt's servers. It travels directly between your machines and the storage clouds.
Performance, availability, and security of the data-plane are never compromised, even if Vawlt's server is down or overloaded.

IMPROVED DATA SECURITY

Vawlt applies an end-to-end encryption protocol to your data, ensuring that only you have access to the content of your files.
All data is encrypted and signed (for privacy and integrity) at client-side using state-of-the-art algorithms (AES256 and RSA2048).
The keys used for these tasks are never sent to Vawlt servers in an unencrypted form.

How did we end up here?

Vawlt's technology has evolved over the last decade with some important peer-reviewed academic publications.
The article introducing the cloud-of-clouds concept is the most cited in the multicloud area.
The first system, that later evolved into Vawlt, was also published at an important conference and you can read it here.
Some of the techniques used in Vawlt were also published for public appreciation and validation. Go have a look here, and here.
The R&D activities leading to Vawlt were funded by 4 EU projects: TCLOUDS (FP7-ICT-257243), BiobankCloud (FP7-ICT-317871), SUPERCLOUD (H2020-ICT-643964), and DiSIEM (H2020-DS-700692).
In all of them, we have partnered with some major players such as IBM Research, Philips Healthcare, Maxdata, Orange, and Sirrix AG to have constant market validation, while accomplishing the projects' goals.
