Achieve Sovereign S3 API Compatibility and Fortify EU Cloud Security
Enterprises require full S3 API compatibility, but balancing this with stringent EU cloud security and data sovereignty is a growing challenge. A sovereign-by-design approach offers a clear path to compliance and resilience.
Key Takeawys
Achieve digital sovereignty and GDPR compliance with S3-compatible object storage hosted exclusively in European data centers.
Eliminate unpredictable costs and vendor lock-in with a transparent pricing model that includes zero egress fees, no API call costs, and no minimum storage duration.
Strengthen ransomware defenses and meet regulatory requirements like NIS-2 and the EU Data Act with features like Immutable Storage (Object Lock) and guaranteed data portability.
In 2025, European IT leaders face a dual mandate: maintain seamless application performance with 100% S3 API compatibility while ensuring absolute compliance with EU data laws. The risk of exposure to non-EU regulations like the CLOUD Act complicates reliance on traditional providers. This article outlines how to achieve robust S3 API compatibility within a sovereign cloud security framework. We explore an architecture that guarantees EU data residency, eliminates unpredictable costs, and aligns with upcoming regulations like the EU Data Act, offering a practical blueprint for secure, compliant, and efficient cloud operations.
Establish Digital Sovereignty with S3 API Control
A strong majority of EU decision-makers now demand European solutions for their critical data infrastructure. This shift is driven by the need to secure data within EU legal frameworks, avoiding exposure to foreign laws. Our platform is operated exclusively in certified European data centers, offering country-level geofencing to guarantee data residency. This ensures 100% GDPR compliance from day one. With enterprise cloud data flows in Europe expected to grow by 200% by 2030, a sovereign strategy is essential for future growth. This foundation of EU-centric governance is the first step in building a resilient cloud security posture.
Deploy Enterprise-Ready S3 API Compatibility
True S3 API compatibility protects your technology investments by ensuring your existing tools and applications work without modification. Our service supports advanced S3 capabilities, including versioning, lifecycle management, and event notifications across any API, CLI, or SDK. This prevents the need for costly code rewrites, minimizing migration risk for 100% of your S3 workloads. We provide a seamless transition, allowing your teams to maintain operational continuity with zero disruption. This comprehensive compatibility is critical for leveraging your existing S3 data security protocols.
Here is what enterprise-ready S3 compatibility includes:
Full support for standard object operations (GET, PUT, DELETE).
Advanced features like versioning and lifecycle management.
Seamless integration with leading backup tools, including our NovaBackup collaboration.
Consistent performance for both API and command-line interface (CLI) tools.
Support for presigned URLs for time-bounded data access.
This level of integration ensures that your established data pipelines continue to function reliably.
Architect for Predictable Performance and Cost
Many cloud models introduce complexity and cost through data tiering, leading to restore delays and API timeouts. Our “Always-Hot” object storage model ensures all data is immediately accessible, simplifying operations for 100% of your datasets. This architecture provides strong read/write consistency and predictable latencies, eliminating hidden operational costs. Our pricing model is predictable by design, with zero egress fees or API call costs. This transparency allows for precise budget forecasting, a key criterion for over 80% of EU enterprises evaluating cloud providers. Learn more about our approach to secure data management.
Align with EU Regulations: GDPR, NIS-2, and the Data Act
Navigating the European regulatory landscape is a primary concern for IT leaders. Our platform is built to meet these challenges head-on. From October 2024, the NIS-2 Directive requires entities in 18 critical sectors to implement stringent cybersecurity risk-management measures. Our security features, including multi-layer encryption and IAM with MFA, directly support these mandates. Furthermore, the EU Data Act, effective from September 2025, obligates providers to remove switching barriers and ensure data portability. Our commitment to open standards and no lock-in aligns perfectly with these new rules. Explore our dedication to full compliance.
Key regulatory milestones to prepare for include:
GDPR: Continuous adherence to strict data protection and sovereignty rules is mandatory.
NIS-2 Directive: By October 2024, organizations must have robust incident reporting and supply-chain security processes in place.
EU Data Act: From September 2025, customers gain rights to switch providers within a 30-day window, making exit strategies critical.
Our architecture is designed to help you meet these evolving requirements without operational disruption.
Implement Immutable Storage for Ransomware Defense
Ransomware remains a top threat, with attacks impacting thousands of European businesses annually. Immutable Storage with S3 Object Lock is a core defense mechanism, creating a write-once-read-many (WORM) state for your backups. This makes it impossible for data to be altered or deleted for a defined retention period, rendering it secure against ransomware encryption. This feature provides an audit-ready retention policy for 100% of your protected data. It is a foundational element of a modern 3-2-1 backup strategy and a key component of our immutable object storage solution. This proactive defense ensures business continuity even if primary systems are compromised.
Enable MSPs with a Partner-Ready Platform
For our partners, predictable margins and simplified management are paramount. Our commercial model, with zero egress or API fees, allows MSPs to build profitable Backup-as-a-Service offerings with stable costs. The partner console features multi-tenant management with granular role-based access control (RBAC) and MFA for enhanced security. With new distribution agreements with api in Germany and Northamber plc in the UK, we are expanding local access for hundreds of resellers. This partner-centric approach ensures you can deliver sovereign and secure cloud backup solutions to your clients.
