Secure your data within EU borders, eliminate unpredictable costs, and ensure compliance with a cloud storage solution that is sovereign by design.

Key Takeaways

  • True data sovereignty is achieved by using EU-based cloud solutions that operate exclusively in European data centers, ensuring data is governed solely by EU law and avoiding CLOUD Act exposure.
  • A predictable pricing model without egress fees or API call costs is crucial for eliminating vendor lock-in and enabling businesses, especially MSPs, to maintain stable margins.
  • Enterprise-ready features like full S3-API compatibility, immutable storage (Object Lock), and an 'Always-Hot' architecture provide robust ransomware protection and operational resilience without complex tiering.

A strong majority of EU decision-makers now demand European solutions for their critical data infrastructure. Yet, many feel locked into non-EU providers due to complex pricing and legacy systems. The US CLOUD Act creates a direct conflict with GDPR, allowing US authorities to access data stored in the EU if the provider is US-owned. This guide explains how data sovereignty cloud solutions built in Europe provide a practical, enterprise-ready path to digital autonomy, regulatory certainty, and economic predictability for your business.

Establish a Compliant Foundation with EU-Only Data Storage

Storing data exclusively in European data centers is the first step toward digital sovereignty. With 92% of European data residing in U.S. clouds, many businesses are exposed to foreign laws. True data sovereignty cloud solutions guarantee that your data is governed only by EU regulations, providing essential legal certainty. This approach is critical for regulated industries like financial services, which require strict adherence to data residency rules.

Our platform operates exclusively in certified European data centers, offering country-level geofencing to keep your data within predefined regions. This architecture ensures your data never leaves the EU, providing a robust defense against foreign legal demands. This eliminates exposure to the US CLOUD Act completely. Choosing a European provider is a necessity for full GDPR compliance and data protection. This jurisdictional control is the bedrock of a modern data strategy.

Eliminate Vendor Lock-In with a Predictable Economic Model

Many businesses feel trapped by hyperscaler pricing models that include punitive egress fees and API call costs. A significant share of IT leaders prefer a German or EU provider to regain control over their budgets. Predictable cost models are a key driver for switching, with many seeking economic clarity. Our pricing model features zero egress fees, no API call costs, and no minimum storage duration.

This transparent approach delivers predictable margins, a crucial benefit for our MSP and channel partners. The upcoming EU Data Act, fully applicable from September 2025, mandates data portability and aims to prevent vendor lock-in. Our commitment to open standards and a clear exit path aligns perfectly with this regulation. We ensure you can move your data freely, preserving your long-term negotiating power and operational freedom. This financial predictability empowers better business planning.

Deploy Enterprise-Ready Architecture for Performance and Scale

A truly sovereign cloud must also deliver enterprise-grade performance without compromise. Our S3-compatible object storage is built for consistency, availability, and scale, protecting your past investments in tools and scripts. It supports millions of small files as efficiently as large archives, ensuring predictable latencies for any workload. This is achieved through an “Always-Hot” object storage model where all data is immediately accessible.

Here is how our architecture simplifies operations:

  • No Tiering Complexity: Avoids fragile lifecycle policies that cause restore delays and hidden fees.
  • Consistent Performance: Strong read/write consistency ensures stability for backup, analytics, and archival tools.
  • Full S3 Compatibility: Keep your existing applications and workflows running without code rewrites, minimizing migration risk.
  • Resilient by Design: Our decentralized architecture eliminates single points of failure, ensuring high availability.

This robust foundation ensures your operations remain stable and efficient as you scale.

Strengthen Ransomware Defense with Immutable Storage

Ransomware remains a primary threat to business continuity, making immutable backups a critical defense layer. Our platform includes Immutable Storage with Object Lock, a feature that prevents data from being altered or deleted for a specified period. This capability is essential for creating a resilient backup and disaster recovery strategy. Immutable backups render ransomware attacks ineffective, as encrypted files can be restored from a tamper-proof copy.

This security-first approach is integrated with leading backup tools, including a deep collaboration with NovaBackup. The NIS-2 directive mandates stronger risk management and incident response capabilities for businesses across the EU. Implementing immutable storage is a key step toward meeting these new cybersecurity requirements. It provides an audit-ready retention solution that safeguards your most critical assets. This proactive security posture prepares you for future regulatory demands.

Prepare for Evolving EU Data Regulations

The European regulatory landscape is continuously evolving to strengthen data rights and security. Two key regulations are shaping the future of data management for every EU business. Staying ahead of these changes provides a significant competitive advantage.

Key upcoming regulations include:

  1. The EU Data Act (September 2025): This regulation champions data portability and interoperability by design. It requires cloud providers to offer a clear exit path, including metadata and access information, to eliminate lock-in.
  2. The NIS-2 Directive: This directive mandates continuous security processes, including supply-chain assurance and strict incident reporting timelines. It requires organizations to bake security into their operations, not treat it as an afterthought.

Our compliance-focused solutions are designed to meet these standards, helping you navigate the complexities of EU data law.

Enable Channel Partners with a Predictable and Scalable Platform

For MSPs, resellers, and system integrators, predictable margins are essential for building a profitable service portfolio. Our partner-ready platform is designed to support the channel with a transparent economic model. The absence of egress and API fees allows partners to offer Backup-as-a-Service (BaaS) and archiving solutions with stable, defensible margins. This predictability transforms cloud storage from a cost center into a profit engine.

We provide a multi-tenant management console with robust IAM, MFA, and RBAC capabilities. Partners can automate workflows and reporting via our full API/CLI support, ensuring fast and simple onboarding for new customers. Our expanding distribution network, including api in Germany and Northamber plc in the UK, provides local access and support for our growing partner ecosystem. This commitment to the channel ensures our partners have the tools they need to succeed.
