Why European companies choose European Cloud Vault
European Cloud Vault is the geo-distributed object storage solution developed by WIIT in partnership with Cubbit, which is revolutionising the enterprise storage paradigm. It abandons the centralised S3 model of hyperscalers in favour of DS3 (Distributed S3): total data sovereignty, extreme resilience and predictable costs.
Based on DS3 technologyThe benefits of European Cloud Vault, WIIT’s sovereign object storage
At the heart of our European Cloud Vault is WIIT’s Secure Cloud approach: a geo-distributed and fully managed presence across European territory, organised into Regions, which is essential for providing companies with the highest level of regulatory compliance and data territoriality.
Thanks to this combination, these are the advantages you can obtain:

Digital Sovereignty: your data remains in Europe
With European Cloud Vault, data, metadata, networks and backup processes remain entirely within the European Union, including Switzerland. You are no longer subject to the US Cloud Act or FISA.
Hyper Resiliency: durability up to 15 9s
DS3 technology (Distributed S3) distributes your encrypted data across 19 proprietary WIIT data centers in 7 European geographic regions. This means that even in the event of a total failure of a region, your data remains accessible without interruption.
2X Ransomware Protection:
- Client side: Object Lock for immutability
- Server side: Versioning + geo-distribution that prevents simultaneous compromise
Savings up to 80% compared to hyperscalers
European Cloud Vault drastically reduces storage costs thanks to:
- Transparent and predictable pricing
- Technical optimisation
Zero-Knowledge: only you have the keys
European Cloud Vault implements a Zero-Knowledge approach by design:
- Only the user has access to the encryption keys
- Not even WIIT or Cubbit can access your content
- End-to-end encryption throughout the entire lifecycle
- BYOK (Bring Your Own Key) option available
Security certifications:
| ✓ ISO 27001 | ✓ GDPR | ✓ NIS2 | ✓ DORA |

What is Object Storage
Enable the Future of Cloud Storage
Object Storage is a new model for archiving information, designed to scale regardless of the volume of data. Inherently secure and fast.
Unlike traditional file systems that manage data as hierarchy or blocks, Cloud Object Storage manages data as “objects”, associated with metadata and a globally unique identifier. These systems are designed to retain large amounts of unstructured data, where data is written once and read multiple times.
The benefits of Cloud Object Storage
Scalable
Ideal to store PB of unstructured data in a cost-efficient way
Fast
Download and upload your data using parallel connections, wherever you are
Secure
Protect your data from ransomware using built-in functionalities
Plugged-in
S3 compatible to minimize migration time from your current object storage
100% S3 compatibility: risk-free migration
European Cloud Vault has been designed to be fully compatible with the S3 standard, meaning you can immediately integrate it with your existing applications without any need to rewrite code. Full compatibility with S3 APIs ensures you have complete support for all the features you already use, such as Object Lock, Versioning, and Lifecycle policies, making migration from hyperscaler solutions a straightforward and seamless process.
The transition to European Cloud Vault is so immediate that the only change required in your code is updating the endpoint. Everything else remains the same, allowing you to maintain your operational workflows and the team’s expertise already acquired on the S3 standard.
European Cloud Vault integrates seamlessly with the WIIT Cloud Native Platform (WCNP) ecosystem, enabling you to benefit from a consistent and fully orchestrated infrastructure. This native integration ensures your storage automatically inherits the distinctive features of the WIIT platform: multi-region resilience for maximum operational continuity, digital sovereignty with European governance, and economic optimisation across your entire cloud infrastructure.
Secure, resilient, cost effectiveHow does WIIT’s DS3 work?
European Cloud Vault, WIIT’s sovereign object storage service, developed and offered in collaboration with Cubbit, uses DS3 technology, transforming the way data is stored in the cloud. With our secure, resilient and cost-effective solution, your data is distributed throughout Europe via our data centers.
Instead of storing data in a single location, your data is encrypted, split into parts and replicated as objects in a geo-distributed network where you have full control and ownership of your data, infrastructure and costs.
Unmatched resiliency with geo-distribution
Geo-distribution means unmatched resiliency for an Object Storage. Data is no longer duplicated and stored in different locations, but it is actually distributed in more than one region, in data centers located in Europe.
To access a file from the geo-distributed object storage you don’t need all locations to be reachable at the same time. In fact, if you choose a multi-region setup, even if you lose an entire region, you can continue to access your data without any disruption.

De Agostini EditoreCase Study
The challenge: De Agostini Editore (DeAKids, DeAJunior, KidsMe) manages a vast digital archive of media content for young audiences. They needed a solution to store 1 Petabyte of digital archive while ensuring reliability, accessibility and cost efficiency.
The solution: Complete migration to European Cloud Vault with 100% European technology (WIIT + Cubbit).
The results:
• Performance comparable to global hyperscalers
• Full data sovereignty within the EU
• Optimisation of storage costs compared to traditional alternatives
• Highest standards of security, resilience and compliance
