How European healthcare providers can protect patient data with UK-based, compliant cloud storage, eliminating risks from non-EU laws and unpredictable costs.

For doctors and healthcare providers in the UK and EU, ensuring every secure file transfer meets stringent regulatory standards is a daily operational challenge. The General Data Protection Regulation (GDPR) classifies health data as a special category, requiring explicit consent and robust security for its processing and transfer. With the rise of ransomware attacks and the complexities of international data laws like the CLOUD Act, relying on non-EU cloud services introduces significant compliance and security risks. This article outlines a sovereign cloud storage approach that keeps patient data exclusively within UK data centres, offering a predictable, compliant, and resilient solution for modern medical practices.

Key Takeaways

  • Secure file transfer for doctors requires a sovereign cloud solution that guarantees UK data residency and GDPR compliance to protect sensitive patient information.
  • Immutable storage with S3 Object Lock is a critical defense against ransomware, ensuring that patient records can be recovered quickly and without data loss.
  • A transparent pricing model with no egress or API fees provides predictable costs, eliminating the budget uncertainty common with hyperscale cloud providers.

Meet Data Sovereignty Mandates for Patient Records

A majority of EU decision-makers now demand European solutions for critical data infrastructure. For doctors, this means ensuring patient records are subject only to UK laws, avoiding exposure to foreign legal frameworks. Storing data within a specific country is a key requirement for many healthcare regulations. Impossible Cloud guarantees this with country-level geofencing in certified European data centers. This approach provides the EU legal certainty needed for a compliant sovereign cloud strategy. This ensures that secure file transfer for doctors aligns with national and EU-wide data protection standards.

This commitment to UK data residency is the foundation for building a trusted healthcare data ecosystem.

Achieve Demonstrable GDPR and UK NIS Regulations Compliance

Under GDPR, transferring health data outside the EU requires strict safeguards. The UK NIS Regulations further expands cybersecurity obligations for the healthcare sector, mandating continuous security processes and supply-chain assurance. Our platform is sovereign by design, aligning with these regulations from day one. We provide the tools for audit-ready data retention and EU-controlled key management. This simplifies the path to GDPR compliance for any medical practice. Our architecture helps you meet the continuous security demands of UK NIS Regulations without extra complexity.

Here is how we support regulatory readiness:

  • Operate exclusively in certified UK data centres to meet data residency rules.
  • Provide immutable storage with Object Lock for audit-ready retention policies.
  • Support geofencing to keep data within predefined national borders under UK law.
  • Enable granular, role-driven access control via IAM with MFA and SAML/OIDC integration.

This built-in compliance framework reduces regulatory risk and allows doctors to focus on patient care.

Defend Against Ransomware with Immutable Backups

Ransomware attacks on healthcare can disrupt services for over 10 days, costing millions. A secure file transfer for doctors must include robust protection against such threats. Our solution offers Immutable Storage using S3 Object Lock. This feature makes files unchangeable for a set period, rendering ransomware encryption useless. It is a core component of a modern ransomware protection strategy. By creating an unalterable copy of patient data, you ensure a clean recovery point is always available. This aligns with a resilient secure cloud backup posture.

With immutable backups, practices can restore operations within hours, not weeks, following an attack.

Integrate Seamlessly with Zero Rewrites or Lock-In

Most healthcare providers already use a variety of applications and scripts for data management. Our platform offers full S3-API compatibility, ensuring these existing tools keep working without modification. This protects past IT investments and eliminates migration friction. The upcoming EU Data Act, effective from September 2025, mandates data portability by design. Our use of open standards ensures you can always move your data, avoiding vendor lock-in. This commitment to interoperability is central to a sustainable, long-term data strategy.

Key integration features include:

  1. Full support for S3 API, CLI, and SDKs for existing applications.
  2. Out-of-the-box integrations with leading backup tools like NovaBackup.
  3. Support for advanced S3 capabilities like versioning and lifecycle management.
  4. An "Always-Hot" object storage model, ensuring data is always accessible without restore delays.

This technical alignment ensures a smooth transition and reliable daily operations for any medical practice.

Gain Cost Predictability with a Transparent Economic Model

Many cloud providers attract users with low storage prices but impose high fees for data egress or API calls. This creates unpredictable monthly bills, a major pain point for over 75% of cloud customers. We eliminate these hidden costs entirely. Our model includes zero egress fees, zero API call costs, and no minimum storage duration. This transparent approach provides the economic clarity that healthcare IT leaders need for effective budget planning. It also gives Managed Service Providers (MSPs) serving the medical sector predictable margins for their backup and archiving services. This clear economic model is a key part of our compliance and value proposition.

Predictable costs empower better financial planning and remove the risk of billing surprises.

Enable Partners with a Channel-Ready Platform

We equip MSPs and resellers to deliver sovereign, compliant storage solutions to their healthcare clients. The partner console offers multi-tenant management, automation via API/CLI, and detailed reporting. This simplifies onboarding and administration, allowing partners to scale their services efficiently. Predictable margins are built-in, thanks to our zero-fee structure for egress and API calls. Our expanding distribution network, including api in Germany and Northamber plc in the UK, provides local access and support for our partners. This makes it easier than ever to offer a compliant file sharing solution to regulated industries.

Our partner-ready platform is designed to fuel channel growth and success in the European market.

FAQ

How does your solution ensure compliance with the EU CLOUD Act?

Our solution mitigates CLOUD Act exposure by being a European company that stores all data exclusively in certified European data centers. This 'sovereign by design' approach ensures that your data is governed solely by UK laws, providing legal certainty that non-UK providers cannot guarantee.

Is your storage platform compatible with my existing backup software?

Yes. Our platform offers full S3-API compatibility, which means it integrates seamlessly with virtually all modern backup and data management tools that support the S3 protocol. This allows you to continue using your existing applications without needing to rewrite code or change workflows.

What makes your pricing model 'predictable'?

Our pricing is predictable because we have a transparent, all-inclusive model. We charge only for the storage you use and have no egress fees, no API request charges, and no minimum storage durations. This eliminates the variable, hidden costs that make budgeting so difficult with other cloud providers.

How does 'Always-Hot' storage benefit a medical practice?

Our 'Always-Hot' storage model ensures all data, whether it's a recent file or a long-term archive, is immediately accessible without any delays or restore fees. For doctors, this means critical patient information is always available on demand, which is vital for urgent care scenarios and simplifies data management.

What is S3 Object Lock and why is it important for doctors?

S3 Object Lock is a feature that makes data immutable, meaning it cannot be altered or deleted for a specified period. For doctors, this is a powerful tool against ransomware, as it ensures that even if a network is compromised, the backup copies of patient records remain safe and unencrypted, guaranteeing a reliable recovery.

How do you support Managed Service Providers (MSPs)?

We provide MSPs with a partner-ready platform featuring a multi-tenant console, full automation via API/CLI, and comprehensive reporting. Our predictable pricing model allows MSPs to build services with stable, defensible margins. We also offer support through our growing network of European distributors.
