How European enterprises achieve compliance, predictable costs, and ransomware protection without vendor lock-in.

A majority of EU decision-makers now demand European solutions for their critical data infrastructure. Yet, many feel locked into existing providers by complex pricing and fear exposure to non-EU laws like the CLOUD Act. The key advantages of object storage services designed for digital sovereignty directly address these pains. By prioritizing EU data residency, 100% S3 compatibility, and a transparent economic model with zero hidden fees, businesses can finally align their cloud strategy with their governance requirements. This guide details the enterprise-ready capabilities that make this transition practical, from resilient architecture to baked-in regulatory readiness for the EU Data Act.

Key Takeaways

  • Object storage offers digital sovereignty through EU-only data centers, avoiding CLOUD Act exposure and ensuring GDPR compliance.
  • A primary advantage is predictable costs with zero egress fees, zero API call costs, and no minimum storage duration, leading to a lower TCO.
  • Full S3 compatibility and an "Always-Hot" architecture ensure seamless migration for 100% of existing tools and consistent, immediate data access without tiering delays.

Achieve 100% S3 Compatibility for Seamless Migration

True S3 compatibility protects your technology investments across dozens of applications. It ensures your existing apps, scripts, and tools continue working with zero code rewrites. This advantage minimizes migration risk for 100% of your workflows. Our service supports advanced capabilities beyond basic object operations. Explore S3 compatibility benefits to see how we protect your past investments.

This includes consistent support for features across the API, CLI, and SDKs. Here is what that means in practice:

  • Full support for object versioning to track changes over time.
  • Automated lifecycle management to handle data retention policies.
  • Reliable event notifications to trigger downstream workflows.
  • Seamless integration with hundreds of third-party backup tools.

This level of compatibility keeps your established data pipelines running without interruption. This foundation of interoperability is the first step toward a more flexible cloud strategy.

Leverage an Always-Hot Architecture for Consistent Performance

Complex data tiering introduces risk, delays, and surprise fees during urgent restores. Our architecture provides a key advantage with an “Always-Hot” object storage model. All data is immediately accessible with zero tier-restore delays. This model handles millions of small files and large archives with equal efficiency. It reduces operational complexity for your IT team of 5 or 50.

This approach guarantees predictable latencies for mixed workloads, from analytics to archival. Multi-AZ replication ensures data integrity under any workload pattern. Fragile tiering policies often lead to API timeouts and hidden operational costs of up to 30%. An always-hot model, as detailed in our guide to storage for large files, keeps your tools stable and your restores predictable. This architectural choice is fundamental to building a resilient data environment.

Implement Granular IAM to Reflect Your Organization

Effective governance requires identity and access management that maps to your real-world teams. Our platform provides identity-based IAM with granular, role-driven policies (RBAC). Secure defaults and multi-factor authentication (MFA) are standard for 100% of accounts. We also support external IdPs via SAML/OIDC for streamlined user management.

Our console UX is designed for the 99% of users who are not API experts. It simplifies dozens of critical tasks without requiring deep technical knowledge. You can manage everything in just a few clicks. Secure object storage starts with controlling who can access it. This focus on usability empowers teams to manage permissions securely and efficiently. Proper access control is your first line of defense against data breaches.

Guarantee EU Control Over Security and Compliance

Digital sovereignty is achieved by keeping data under strict EU legal control. Our service operates exclusively in certified European data centers. This provides country-level geofencing to meet GDPR and other regional data residency rules. We eliminate exposure to the CLOUD Act for 100% of data stored with us. This offers EU legal certainty that non-EU providers cannot match.

Our multi-layered security model provides robust protection. Here are 4 key features:

  1. Verified encryption for data in transit and at rest.
  2. EU-controlled key management, including full revocation procedures.
  3. Immutable Storage with Object Lock for audit-ready retention.
  4. Ransomware defense capabilities built into the platform's core.

Immutable backups via Object Lock make your data unchangeable for a set period. This is one of the most powerful advantages of our platform for defending against ransomware. This comprehensive security posture prepares you for the next generation of threats.

Turn Regulatory Readiness into a Competitive Advantage

Staying ahead of regulations is a significant competitive advantage. Our platform is built with future EU rules in mind. This includes the EU Data Act, which takes full effect from September 2025. It mandates data portability and interoperability by design, including all metadata and versions. We provide a real exit path with zero lock-in, aligning with the Act's core principles.

We also address the NIS-2 directive's requirements for continuous security. Our operations include documented incident reporting timelines and robust supply-chain assurance. These processes are baked into our service, not added as an afterthought. This proactive stance on compliance reduces risk for thousands of our customers. Understanding the benefits of cloud data management under these new rules is key to future-proofing your business.

Secure Predictable Economics with a Transparent Cost Model

One of the most critical advantages of modern object storage services is economic predictability. Our pricing model is transparent by design. We have zero egress fees, zero API call costs, and no minimum storage durations. This eliminates the billing surprises that affect over 60% of businesses using hyperscale clouds. Your costs are based on one simple metric: the amount of data you store.

This model provides guaranteed service levels as reliable inputs for your business planning. Predictable costs can lower your total cost of ownership (TCO) by over 50% in 3 years. Regional proximity of our EU data centers also ensures low latency for your applications. For a deeper look, see our analysis on cost-efficient S3 storage. This financial clarity allows you to scale without fear of hidden charges.

Empower Channel Partners with a Predictable Value Proposition

For MSPs, resellers, and system integrators, predictable margins are paramount. Our partner-ready platform is predictable by design. The zero-fee model allows partners to build BaaS and archiving services with stable, defensible margins of 30% or more. The multi-tenant partner console simplifies management with RBAC and MFA controls. Automation via our full API/CLI and clear reporting tools enable fast onboarding for hundreds of clients.

We are expanding local access for our partners across Europe. Our 2025 distribution milestones include adding api in Germany and Northamber plc in the UK. This growing ecosystem provides our partners with strong local support and streamlined procurement. Our object storage guide helps partners explain these benefits to their clients. A strong partner channel is essential for delivering these advantages to the wider market.
