The cloud-of-clouds.

Vawlt allows you to store your data in multiple clouds, simultaneously, thus creating a cloud-of-clouds. Your data is available and secure even if some of the clouds are down, if they lose or corrupt your data,and also if they are hacked. We have been working hard on this technology for the past decade to make sure we are doing it right.

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. The data is encrypted and signed (for privacy and integrity) at client-side using state-of-the-art algorithms (AES256 and RSA2048). The keys used in these tasks are never sent to Vawlt servers in an unencrypted form.

A data-centric architecture

Contrary to all the other cloud storage services, with Vawlt your data never goes through our servers; it goes directly from your machines to the storage clouds, and vice-versa. Due to this fact, the performance, availability, and security of the system data-plane is not compromised even if our server is down or overloaded.

How did we end up here?

Vawlt's technology has evolved over the last decade with some important peer-reviewed publications in the academic sphere.
The article introducing the cloud-of-clouds concept is the most cited in the multcloud 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.
