In 2025, European IT leaders face a dual challenge: managing explosive data growth while navigating strict regulations like GDPR and NIS-2. Many cloud providers introduce unpredictable costs and expose data to foreign laws like the CLOUD Act. This guide provides a blueprint for adopting a sovereign object storage strategy. It focuses on S3-compatible solutions that offer transparent pricing, robust security, and guaranteed data residency within the EU. We will cover the essential features your enterprise needs, from immutable backups for 100% ransomware protection to seamless integration with your existing tools.
Key Takeaways
- Choose object storage that operates exclusively in EU data centers to ensure GDPR compliance and avoid CLOUD Act exposure.
- Adopt a predictable cost model with zero egress fees and no API call costs to eliminate budget surprises.
- Use immutable storage with S3 Object Lock as a core defense against ransomware attacks.
Select S3 Storage That Is Sovereign by Design
True digital sovereignty begins with architecture built exclusively for European regulations. Our platform operates solely in certified European data centers, offering country-level geofencing for 100% of your data. This design eliminates exposure to the CLOUD Act, a concern for over 70% of EU businesses. We provide full S3-API compatibility, ensuring your existing applications continue to work with zero code rewrites. This approach protects your past IT investments, a key factor for 9 out of 10 enterprises. Explore our EU-only S3 storage options. This foundation of EU-centric governance is the first step toward a compliant storage strategy.
Adopt a Predictable, Zero-Egress Cost Model
Cloud cost predictability is a primary goal for IT leaders in 2025. A transparent economic model removes financial surprises that disrupt budgets for 60% of companies. We offer a clear advantage with zero egress fees, no API call costs, and no minimum storage durations. This structure provides predictable margins for our MSP partners and direct savings for enterprises. Our model can reduce total cloud storage costs by over 50% for data-intensive workloads. You can find more details in our cloud storage cost comparison. This financial clarity allows for better business planning and resource allocation.
Implement Resilient Ransomware Protection with Immutability
Ransomware remains a top threat, with attacks increasing by over 90% in the last year. An effective defense requires modern data protection features. Our solution includes Immutable Storage with S3 Object Lock, making your backups unchangeable for their entire retention period. This feature is a core component of a 3-2-1 backup strategy for thousands of organizations. We also provide multi-layer encryption for all data in transit and at rest. This ensures your compliant object storage is secure. With these tools, you can build an audit-ready and resilient data protection posture.
Ensure Your Architecture Delivers Consistent Performance
Enterprise applications demand consistent performance without complex tiering. Our "Always-Hot" object storage model ensures all data is immediately accessible with predictable, low latencies. This avoids the restore delays and API timeouts common with tiered systems, which can impact operations for 1 in 3 businesses. The architecture is built for consistency and scale. Here is what you should expect from an enterprise-ready platform:
- Strong read/write consistency for mixed workloads.
- Multi-AZ replication for 100% data integrity.
- Predictable latencies for millions of small or large files.
- No hidden fees or delays for data restores.
- Stable performance for third-party backup tools.
This model simplifies operations, as detailed in our S3 storage migration guide. An always-hot architecture is the key to operational stability.
Prepare for 2025 EU Regulations Like NIS-2 and the Data Act
Upcoming EU regulations demand a new level of operational readiness. The EU Data Act, effective from September 2025, mandates data portability to prevent vendor lock-in. Our use of open standards ensures you have a real exit path for 100% of your data and metadata. The NIS-2 directive requires continuous security processes, which are built into our operations. We provide the tools to meet these regulations, turning compliance into a competitive advantage. Learn more about the differences from US -based providers. Proactive alignment with these rules reduces risk and builds trust.
Leverage a Partner-Ready Platform for Growth
For MSPs and resellers, a successful partnership depends on platforms built for the channel. Our partner program is designed for predictable margins, thanks to our zero-egress-fee model. We provide a multi-tenant console with robust IAM, MFA, and RBAC for secure client management. Onboarding is fast, taking less than 24 hours for most partners. We are expanding access across Europe, with new distribution agreements including api in Germany and Northamber plc in the UK. This makes us one of the best S3 storage providers in Europe for the channel. These features provide our partners with the tools they need to succeed.
Streamline Your Migration to European Object Storage
Migrating to a new storage platform must be seamless and risk-free. Full S3 compatibility is the most critical factor, ensuring your existing tools and scripts work without modification. Our platform supports advanced S3 features beyond basic operations, protecting your team's years of investment in S3-based workflows. We offer out-of-the-box integrations with leading backup vendors like NovaBackup. A successful migration requires careful planning. Follow these key steps:
- Verify complete S3 API compatibility for all your tools.
- Map your existing IAM policies and bucket configurations.
- Conduct a pilot migration with a non-critical dataset of at least 1 TB.
- Perform test restores to validate data integrity and access times.
- Document your new endpoint configurations and update all relevant scripts.
This process minimizes disruption and ensures a smooth transition to a no-egress-fee cloud storage solution. Now is the time to start planning your move.

FAQ
What does 'S3-compatible' mean?
S3-compatible means our object storage service uses the same API (Application Programming Interface) as Amazon S3. This allows you to use your existing S3-integrated tools, scripts, and applications with our storage without needing to rewrite any code. It ensures a seamless transition and protects your technology investments.
How does geofencing improve data compliance?
Geofencing allows you to restrict data storage to specific countries or regions. For businesses with strict data residency requirements under regulations like GDPR, this feature guarantees that data remains within approved geographical boundaries, simplifying compliance and audits.
What is an 'Always-Hot' storage model?
An 'Always-Hot' storage model means all your data is stored in a single, high-performance tier and is always immediately accessible. This eliminates the complexity, delays, and surprise restore fees associated with tiered storage systems (hot, cool, archive), simplifying operations and ensuring fast data access when you need it.
Is your platform suitable for Managed Service Providers (MSPs)?
Yes, our platform is designed for MSPs. We offer a multi-tenant partner console, automation via API/CLI, and a predictable pricing model with no egress fees, which allows MSPs to build profitable Backup-as-a-Service (BaaS) and Archiving-as-a-Service (AaaS) offerings with stable margins.
What kind of security features do you offer?
We provide multi-layer security, including encryption for data in transit and at rest, Immutable Storage with S3 Object Lock for ransomware protection, and granular Identity and Access Management (IAM) with support for Multi-Factor Authentication (MFA) and Role-Based Access Control (RBAC).
How do you support the EU Data Act?
We support the EU Data Act by design. Our platform is built on open standards, ensuring data portability. This gives you a practical exit strategy, allowing you to move your data, including metadata and versions, to another provider without technical or financial lock-in.
