How EU-centric, geofenced object storage delivers compliance, predictable costs, and resilience against cyber threats.

UK councils are prime targets for cybercriminals, facing a constant barrage of ransomware threats that can halt public services. Traditional data protection methods are no longer sufficient. Achieving robust immutable ransomware protection for UK councils requires a modern approach grounded in digital sovereignty, advanced security, and cost predictability. This guide outlines how UK-based object storage with features like Immutability (Object Lock) provides a resilient, compliant, and financially stable solution. It is designed to meet the specific challenges of the UK public sector, ensuring data remains secure, accessible, and under EU legal control, free from CLOUD Act exposure.

Key Takeaways

  • UK councils can achieve true data sovereignty and avoid US CLOUD Act exposure by using UK-only, geofenced object storage.
  • Immutable storage with Object Lock is the most effective defense against ransomware, guaranteeing a clean and rapid recovery path.
  • A transparent pricing model with zero egress or API fees allows councils to achieve predictable, stable budgets for data storage and protection.

Counteract Foreign Data Access Laws

A significant number of EU decision-makers now demand European solutions for critical infrastructure. Storing data with non-UK providers creates exposure to foreign laws like the US CLOUD Act, which can compel access to data regardless of its location. This directly challenges the UK's data sovereignty principles. Impossible Cloud operates exclusively in certified European data centers, providing a 100% EU-centric governance model. This design eliminates CLOUD Act exposure entirely. Our country-level geofencing guarantees that council data stays within predefined regions under EU rules, ensuring full compliance. This focus on a sovereign cloud provides the legal certainty UK councils require.

Implement Unbreakable Ransomware Defense with Immutability

Ransomware attacks against UK victims surged by 233% between 2020 and 2021, making resilient backups essential. Immutable storage, or Object Lock, is the definitive defense mechanism. It makes data unchangeable and undeletable for a set period, creating a secure copy that ransomware cannot touch. Even if primary systems are compromised, an immutable backup ensures a clean, rapid recovery is always possible. This approach transforms disaster recovery from a possibility to a certainty.

Key benefits of immutable backups include:

  • Guaranteed Recoverability: Creates a tamper-proof copy of data, ensuring at least one version is always clean.
  • Regulatory Compliance: Meets stringent data retention policies for audits with a 100% verifiable data trail.
  • Protection Against Insider Threats: Prevents accidental or malicious deletion by internal actors for its entire retention period.
  • Simplified Operations: Eliminates complex tiering, making all data immediately accessible in an "Always-Hot" model.

This strategy provides a powerful, modern defense against escalating cyber threats.

Align with UK Regulations and Predict Costs

For UK councils, regulatory readiness is a competitive advantage. Our platform is designed to align with key UK regulations from day one. This includes GDPR, the UK NIS Regulations for supply-chain assurance, and the EU Data Act, which mandates data portability from September 2025. We provide the tools to meet these standards, including robust IAM with MFA/RBAC and end-to-end encryption. Our transparent pricing model has zero egress fees or API call costs. This means councils can budget with 100% accuracy, avoiding the surprise fees that plague other cloud providers. This economic clarity is a key driver for public sector organisations seeking stable, long-term solutions for secure cloud backup.

Leverage an Enterprise-Ready, S3-Compatible Architecture

Switching storage providers should not require rewriting applications. Impossible Cloud offers full S3-API compatibility, ensuring your existing tools and scripts continue to work without modification. Our architecture is built for consistency and scale, handling millions of files with predictable low latency. The "Always-Hot" storage model means every piece of data is instantly accessible, with zero restore delays. This avoids the hidden operational costs and API timeouts common with tiered systems, which can fail during urgent restores over 30% of the time.

Our enterprise-ready platform includes:

  1. Advanced S3 Compatibility: Full support for versioning, lifecycle management, and event notifications.
  2. High Availability: Multi-AZ replication eliminates single points of failure, guaranteeing data integrity.
  3. Granular Access Control: Identity-based IAM maps to real organizational structures with support for SAML/OIDC.
  4. Intuitive Console UX: Manage buckets, roles, and permissions easily without deep API expertise.

This robust foundation ensures a seamless migration and reliable daily operations for any G-Cloud approved supplier.

Empower UK MSPs and Resellers with a Partner-Ready Platform

We enable our UK partners to deliver sovereign and compliant backup solutions with predictable margins. The absence of egress and API fees allows MSPs to build defensible pricing for BaaS and archiving services. Our partner console is designed for efficiency, featuring multi-tenant management, RBAC, MFA, and comprehensive reporting. Onboarding is fast, taking less than 60 minutes. With our first UK distributor, Northamber plc, local access for resellers and system integrators is more streamlined than ever. This partner-centric approach helps MSPs capitalize on the growing demand for Veeam sovereign storage and other integrated solutions.

Follow Practical Steps for a Resilient Backup Strategy

Implementing immutable ransomware protection for UK councils is straightforward with a clear plan. A modern 4-2-2 backup strategy offers enhanced resilience over the traditional 3-2-1 model. It involves creating four copies of your data, stored on two different media types, with two copies offsite, one of which is immutable. This provides at least one guaranteed recovery point.

Your migration checklist should include these steps:

  • Define Endpoints: Confirm your S3-compatible application endpoints and credentials.
  • Set Bucket Policies: Create new buckets with Object Lock enabled from the start.
  • Configure Lifecycle Rules: Establish automated data retention and deletion policies for compliance.
  • Migrate Data: Use our tools for seamless bulk data movement with 100% integrity.
  • Test Restores: Regularly perform test restores to validate your recovery procedures and ensure readiness.

FAQ

Is Impossible Cloud compliant with GDPR?

Yes, Impossible Cloud is sovereign by design and fully GDPR-compliant. We operate exclusively in certified European data centers and offer country-level geofencing to ensure data residency and adherence to all EU data protection regulations.

Can I use my existing backup software with Impossible Cloud?

Yes. Impossible Cloud is fully S3-API compatible, which means it integrates out-of-the-box with leading backup tools and any other applications that use the S3 protocol. No code rewrites or complex configurations are needed.

What does 'no egress fees' mean for a council's budget?

No egress fees means your council will never be charged for retrieving or moving its data out of our storage. This eliminates unpredictable costs, which often account for a large portion of a cloud bill, and allows for precise, stable budgeting.

How does Object Lock work?

Object Lock is a feature that allows you to set a retention policy on your data. Once set, the data cannot be altered or deleted by anyone-including administrators-until the retention period expires. This creates a WORM (Write-Once-Read-Many) model perfect for ransomware-proof backups.

What is an 'Always-Hot' storage model?

An 'Always-Hot' storage model means all your data is immediately accessible at all times, without any delays or extra fees for retrieval. This simplifies operations by removing the need for complex and fragile data tiering policies, ensuring fast restores when you need them most.

How can our MSP start working with Impossible Cloud in the UK?

UK-based MSPs and resellers can get started quickly through our distributor, Northamber plc. Our partner program offers a multi-tenant management console, full automation via API/CLI, and predictable margins to help you build compelling BaaS and DR solutions for your clients.
