How European-based, S3-compatible object storage delivers data privacy, ransomware resilience, and predictable costs for enterprise IT and MSPs.

For UK and EU businesses, ensuring secure object storage data privacy under GDPR is a top priority. A strong majority of EU decision-makers now demand European solutions for their critical data. This shift is driven by the need for digital sovereignty and the avoidance of CLOUD Act exposure. Choosing an EU-based storage provider guarantees data residency and aligns with strict regulatory frameworks. It also eliminates unpredictable costs from egress fees and complex tiering, offering a practical path to compliance without sacrificing performance.

Key Takeaways

  • Achieve digital sovereignty and GDPR compliance by using EU-only geofenced object storage, which eliminates exposure to foreign laws like the CLOUD Act.
  • Protect against ransomware and ensure data integrity with immutable backups using S3 Object Lock, a core feature of modern data resilience strategies.
  • Eliminate unpredictable cloud costs and vendor lock-in with a transparent pricing model that includes zero egress fees, zero API call costs, and no minimum storage durations.

Meet Data Sovereignty Demands with EU-Only Storage

A majority of EU businesses now list EU data residency as a key vendor selection criterion. Storing data exclusively in certified European data centers provides total immunity from foreign laws like the US CLOUD Act. This approach ensures your data remains under EU legal jurisdiction, a foundational requirement for GDPR compliance. Country-level geofencing keeps data within predefined regions, offering 100% control. This strategy directly addresses the primary market pain point: the risk of dependency on non-EU providers. True digital sovereignty begins with controlling the physical location of your data.

Implement Core GDPR Principles with Compliant Object Storage

GDPR mandates several core principles for data handling, all achievable with the right storage architecture. A compliant platform provides the necessary technical measures to protect personal data from accidental loss or unlawful processing. Key capabilities include:

  • Multi-layer Encryption: All data is secured both in transit and at rest, making it unreadable to unauthorized parties.
  • Data Minimization: Lifecycle management policies can automatically handle data retention, deleting it after a set time.
  • Access Controls: Granular IAM with MFA and Role-Based Access Control (RBAC) ensures only authorized personnel access data.
  • Immutable Storage: Using Object Lock guarantees data integrity and prevents unlawful alteration or deletion.

These features provide the technical safeguards required under GDPR's integrity and confidentiality rules. This prepares your organization for the next step in security: active threat defense.

Defend Against Ransomware with Immutable Backups

Ransomware attacks are increasing by over 150% annually, making immutable backups a critical defense. Impossible Cloud’s secure object storage uses S3 Object Lock to make data unchangeable for a defined period. This means that even if attackers gain access, they cannot encrypt, modify, or delete your backup files. This feature is a core component of modern 3-2-1 and 4-2-2 backup strategies, providing a guaranteed clean recovery point. With out-of-the-box integrations for leading tools like NovaBackup, setting up a resilient ransomware posture takes only minutes. This proactive defense is essential for maintaining business continuity.

Simplify Operations with an 'Always-Hot' Architecture

Complex storage tiering often creates hidden operational costs and restore delays of hours or even days. An “Always-Hot” object storage model ensures all data is immediately accessible with no restore fees or API timeouts. This architecture eliminates the need for fragile lifecycle policies that can fail during urgent recovery events. Every object, from active data to long-term archives, is available with the same low latency. This approach simplifies third-party tool integrations and guarantees predictable performance for the millions of files in a typical workload. It provides the foundation for a truly efficient and encrypted object storage solution.

Achieve Predictable Costs and Eliminate Vendor Lock-In

Many businesses feel locked into their cloud providers due to complex pricing and high data transfer fees. A transparent economic model with no egress fees, no API call costs, and no minimum storage duration breaks this cycle. This predictability is a key driver for switching to EU alternatives, cited by a significant share of IT leaders. This model provides stable, defensible margins for MSPs offering Backup-as-a-Service. Full S3 API compatibility protects existing investments in scripts and tools, enabling a seamless migration that takes less than one day. This focus on open standards ensures you retain long-term control over your data and budget.

Prepare for the EU Data Act and NIS-2 Directive

Upcoming EU regulations further strengthen the case for sovereign storage. From September 2025, the EU Data Act mandates data portability and interoperability by design, ensuring you have a real exit path. The NIS-2 Directive requires continuous security processes, including supply-chain assurance and vulnerability management for critical sectors. A compliant storage partner must demonstrate:

  1. Verifiable Encryption: End-to-end encryption with EU-controlled key management.
  2. Continuous Security: Documented processes for incident reporting, patching, and vulnerability management.
  3. Supply-Chain Assurance: Operations based exclusively in certified EU data centers.
  4. Data Portability: Full support for exporting all data, including metadata and versions, without penalty.

Choosing a provider already aligned with these rules gives you a competitive advantage in regulatory readiness.

Enable Channel Partners with a Partner-Ready Platform

For MSPs, resellers, and system integrators, a partner-centric platform is essential for growth. Predictable margins are built in with a zero-egress-fee model. The platform is designed for the channel with key features that simplify operations. A multi-tenant console with RBAC and MFA allows for secure management of multiple client accounts. Automation via a full-featured API and CLI streamlines onboarding and reporting, reducing administrative overhead by up to 30%. Recent distribution agreements with api in Germany and Northamber plc in the UK expand local access for hundreds of resellers. This momentum provides partners with a clear path to market.

FAQ

How does Impossible Cloud ensure GDPR-compliant data privacy?

Impossible Cloud ensures GDPR compliance by operating exclusively in certified European data centers, providing country-level geofencing to enforce data residency. We implement multi-layer encryption, granular IAM controls, and immutable storage (Object Lock) to meet the regulation's strict requirements for data security, integrity, and confidentiality.


What makes the 'Always-Hot' storage model better than traditional tiering?

The 'Always-Hot' model provides immediate access to all data without the delays or restore fees associated with tiered storage. This simplifies operations, ensures predictable performance for applications, and eliminates the risk of failed restores during critical events, making it a more resilient and cost-effective solution.


Is it difficult to migrate from another S3-compatible provider?

No, migration is straightforward. Because Impossible Cloud is fully S3 API compatible, you can use your existing tools and scripts. The process involves updating the endpoint, access keys, and policies. The absence of egress fees also means you will not face any cost penalties for moving your data.


How does your pricing model benefit MSPs?

Our pricing model is 'predictable by design.' With no egress fees, API call costs, or minimum storage durations, MSPs can build BaaS and archiving services with stable, defensible margins. The multi-tenant partner console and automation tools also reduce operational overhead, making it easier to manage clients and scale.
