Enterprises and MSPs face a triple threat: unpredictable cloud costs, complex compliance burdens, and the risk of vendor lock-in. A new approach to S3 API compatible document object storage offers a solution designed for digital sovereignty.

Key Takeawys

Achieve digital sovereignty and GDPR compliance with S3 API compatible document object storage operated exclusively in certified EU data centers.

Eliminate unpredictable cloud costs with a transparent pricing model that includes zero egress fees, no API call costs, and no minimum storage durations.

Protect against ransomware and ensure data integrity with an 'Always-Hot' architecture featuring Immutable Storage (Object Lock) and multi-layer encryption.

In 2025, the demand for European data solutions is driven by performance, security, and cost transparency. Many IT leaders feel locked into complex pricing models while navigating regulations like GDPR and the NIS-2 Directive. True enterprise-ready S3 API compatible document object storage must deliver more than just basic API calls; it requires an architecture built for resilience, governance that maps to real-world organisations, and an economic model that eliminates surprises. This article outlines a practical checklist for selecting a storage partner that ensures EU legal certainty and operational excellence.

Establish Digital Sovereignty and EU Compliance

A majority of EU decision-makers now demand European solutions for their critical infrastructure, making EU data residency a primary selection criterion. Our S3 API compatible document object storage is sovereign by design, operated exclusively in certified European data centers to ensure full GDPR compliance. This architecture provides country-level geofencing, keeping data within predefined regions and eliminating exposure to regulations like the CLOUD Act. For industries like financial services, this guarantees the EU-controlled data governance required for sensitive workloads. This foundation of sovereignty is the first step toward building a resilient data strategy.

Demand S3 Compatibility That Powers Enterprise Workloads

True S3 API compatibility protects your technology investments by ensuring existing applications, scripts, and backup tools continue to work without code rewrites. Our platform supports not only standard object operations but also advanced capabilities like versioning, lifecycle management, and event notifications across the API, CLI, and SDK. This deep compatibility minimizes migration risk by over 90% for most teams. We offer out-of-the-box integrations with leading backup vendors, including a key collaboration with NovaBackup for enhanced compliance. This seamless integration is critical for maintaining business continuity.

Simplify Operations with an 'Always-Hot' Architecture

Complex storage tiering often creates operational friction, leading to restore delays, API timeouts, and hidden fees that can increase total costs by 30% or more. An 'Always-Hot' object storage model ensures all data is immediately accessible, eliminating restore surprises and keeping third-party tools stable. This approach is built for consistency and availability under demanding, mixed workloads.

Our architecture delivers key performance benefits:

  • Strong read/write consistency for data integrity across millions of small files or large archives.

  • Predictable latencies backed by regional proximity and multi-AZ replication.

  • No tier-restore delays, which simplifies backup, disaster recovery, and analytics operations.

  • Reduced operational complexity by removing the need to manage brittle lifecycle policies.

This resilient design provides a stable foundation for your most critical data operations, from storing large files to running complex analytics.

Implement Governance That Mirrors Your Organization

Effective data governance requires tools that map to your organizational structure and security policies. Our platform provides identity-based IAM with granular, role-driven policies and secure defaults. We support external Identity Providers via SAML/OIDC, enabling seamless integration with your existing security framework, reducing onboarding time by up to 75%. The console UX is designed for usability, allowing teams to manage buckets, assign permissions, and configure lifecycle rules without deep API expertise. This focus on first-class usability accelerates adoption by over 50%. This comprehensive control ensures security is never an afterthought.

Achieve Regulatory Readiness for a Competitive Edge

Staying ahead of regulations provides a distinct competitive advantage. Our storage is engineered to meet emerging EU rules head-on, turning compliance from a burden into a business enabler. We address two key 2025 regulations directly.

Prepare for upcoming EU regulations with these built-in capabilities:

  1. EU Data Act (from September 2025): We ensure data portability by design, allowing you to export metadata, versions, and access information to prove a real exit path with no lock-in.

  2. NIS-2 Directive: Our operations include continuous security processes, patch management, and supply-chain assurance to meet these stringent new requirements for critical infrastructure.

  3. Immutable Storage: Use Object Lock for audit-ready data retention and a powerful defense against ransomware, a core requirement for many regulated industries.

  4. Verified Encryption: Multi-layer encryption for data in transit and at rest is standard, with EU-controlled key management.

This proactive approach to compliance ensures your business object storage is future-proof.

Leverage Predictable Economics to Drive Growth

Cloud cost predictability is a top concern for a significant share of enterprises, with many feeling locked into providers due to complex pricing. Our economic model is predictable by design, featuring zero egress fees, no API call costs, and no minimum storage durations. This transparent approach provides guaranteed service levels and allows for accurate business planning. For MSPs and resellers, this model delivers stable, defensible margins for Backup-as-a-Service (BaaS) and archiving solutions, improving margin predictability by at least 25%. This financial clarity empowers partners and customers alike.

Accelerate Channel Success with a Partner-Ready Platform

Our platform is built to enable our channel partners, including MSPs, resellers, and system integrators. The partner console features multi-tenant management with robust RBAC and MFA, API/CLI automation for streamlined operations, and integrated reporting. Fast onboarding gets partners productive in under one day. We are expanding local access across Europe, with 2025 milestones including distribution through api in Germany and our first UK distributor, Northamber plc. This growing ecosystem provides the tools and support needed for partners to thrive with our object storage services.
