How UK law firms can meet strict regulatory duties using geofenced, UK-based object storage that eliminates CLOUD Act exposure and ensures data sovereignty.

Meeting the Bar Council's stringent data protection standards is a non-negotiable duty for every UK barrister, with guidance recommending data storage exclusively within the UK or EEA. Many firms unknowingly expose sensitive client data to foreign jurisdictions and the US CLOUD Act by using hyperscale providers. True compliance requires a solution built on digital sovereignty. An UK-based, S3-compatible object storage platform offers a direct solution, providing country-level geofencing to guarantee data residency, immutable backups for ransomware defence, and a predictable cost model with zero egress fees. This approach secures data within EU legal frameworks, satisfying regulatory demands.

Key Takeaways

  • The UK Bar Council recommends using cloud storage providers located within the UK or EEA to comply with data protection laws and ensure client confidentiality.
  • Sovereign UK-based cloud storage with country-level geofencing eliminates exposure to foreign laws like the US CLOUD Act, providing essential legal certainty for UK law firms.
  • Features like S3 Object Lock for immutable backups and a zero-egress-fee model are critical for ransomware protection and aligning with the EU Data Act's anti-lock-in principles.

Meet Regulatory Demands with EU Data Residency

The Bar Council explicitly advises using storage providers located in the UK or European Economic Area to ensure an adequate level of security under UK data protection law. This guidance addresses the primary risk of transferring personal data outside a secure legal jurisdiction. Our platform operates exclusively in certified European data centers, eliminating this risk entirely. We provide country-level geofencing to guarantee 100% of your data stays in predefined regions. This directly aligns with the core principle of keeping client data under EU rules. For more on this, see our UK data residency solutions. This focus on localization is the first step toward building a compliant storage strategy.

Eliminate US CLOUD Act Exposure

A significant compliance vulnerability for UK law firms is the US CLOUD Act, which can compel US-based tech companies to provide data to US authorities regardless of where that data is stored. The Bar Council guidance warns of this known risk with service providers in the USA. Storing data with a sovereign EU provider offers complete legal certainty and avoidance of this exposure. Our strictly EU-centric data storage and governance model ensures your firm's data is shielded from such foreign access requests. This provides a crucial layer of protection for privileged client information. You can learn more about how to protect data from the US CLOUD Act. With jurisdictional risks managed, the focus shifts to technical security measures.

Implement Advanced Ransomware Protection with Immutability

Data protection law requires robust technical measures to prevent unauthorised data processing and loss. Ransomware attacks pose a direct threat to the availability and integrity of client files, with the manufacturing sector alone seeing 23% of all cyberattacks in 2022. We provide S3 Object Lock, which makes backups immutable for a set period. This means data cannot be altered or deleted by anyone, creating a powerful defence against ransomware. Key features include:

  • Governance Mode: Allows privileged users to remove locks with specific permissions.
  • Compliance Mode: The highest level of protection, where no user can remove the lock until the retention period expires.
  • Legal Hold: Indefinitely protects objects from deletion, overriding any retention settings.
  • Audit-Ready Retention: Provides a clear, defensible data retention policy for compliance audits.

This feature is a core component of a modern secure cloud backup strategy. Next, consider how your tools will interact with the storage platform.

Preserve Operational Continuity with Full S3 Compatibility

Migrating to a new storage platform should not require rewriting applications or abandoning years of investment in existing tools. Our platform offers 100% S3 API compatibility, ensuring your current apps, scripts, and backup tools continue to work without modification. This goes beyond basic operations to include advanced capabilities like versioning, lifecycle management, and event notifications. This seamless integration protects at least 50% of the typical costs associated with cloud migration projects. This out-of-the-box compatibility is essential for a smooth transition. This approach also prepares your firm for future regulatory requirements concerning data freedom.

Future-Proof Your Practice for the EU Data Act

From September 2025, the EU Data Act will mandate data portability and interoperability, designed to prevent vendor lock-in. The act requires providers to facilitate easy switching, including the transfer of all metadata and access information. Our model is already aligned with this principle. We have zero egress fees, zero API call costs, and no minimum storage durations. This transparent economic model gives you a real exit path, preserving your negotiation power and long-term freedom. This commitment to open standards is a core tenet of a true sovereign cloud for the UK. This financial transparency is a key differentiator.

Achieve Predictable Costs and Defensible Margins

For law firms and the MSPs that serve them, unpredictable cloud bills are a major pain point. Hidden fees for data egress or API calls can inflate costs by over 60% on some platforms. Our transparent pricing model eliminates these variables entirely. This predictability allows for stable, defensible margins on Backup-as-a-Service (BaaS) and archiving solutions. For our partners, we provide a multi-tenant console with robust reporting and automation via API/CLI. With distributors like Northamber plc in the UK, local access for resellers is streamlined. This partner-ready approach simplifies achieving compliance at scale.

Strengthen Security with a Resilient Architecture

A compliant cloud storage solution must be built for high availability and data integrity. Our architecture eliminates single points of failure and uses multi-AZ replication to protect data under mixed workloads. All data is held in an "Always-Hot" object storage model, ensuring 100% of your data is immediately accessible without restore delays. This contrasts with tiered models that can introduce API timeouts and hidden restore fees. Our identity-based IAM, with support for external IdPs via SAML/OIDC, provides granular control over data access. This robust foundation is critical for meeting your obligations under GD PR and other regulations.

FAQ

Is your cloud storage compliant with UK GDPR?

Yes. Our service is sovereign by design, operating exclusively in certified European data centers. This ensures data residency and aligns with all UK GDPR requirements for data protection, security, and processing, as detailed in our comprehensive compliance documentation.

How do you ensure data is not transferred outside the EU?

We utilize strict, country-level geofencing. When you select a storage region, your data is physically and legally stored only within that country's certified data centers. It is never moved or replicated outside of your chosen sovereign boundary, guaranteeing data residency.

What are egress fees and do you charge them?

Egress fees are charges that cloud providers levy when you retrieve or move your data out of their cloud. We do not charge any egress fees, API call costs, or have minimum storage durations. Our pricing is transparent and predictable, allowing you to access your data as needed without financial penalty.

Can I use my existing backup tools like Veeam with your storage?

Absolutely. Our platform is fully S3-compatible and has out-of-the-box integrations with leading backup tools, including Veeam and our partner NovaBackup. You can connect your existing backup software directly to our storage endpoints without any changes to your workflow.

How does your platform help with UK NIS Regulations compliance?

The UK NIS Regulations requires strong supply chain security. As your storage provider, we help you meet this by offering a secure, resilient, and compliant platform with multi-layer encryption, robust IAM controls, and certified UK-only data centers, simplifying your own compliance audits.

How can I migrate my existing data to your platform?

Migration is straightforward due to our full S3 API compatibility. You can use any S3-native tool, script, or the AWS CLI to move your data. Our console provides tools for monitoring, and our support team is available to guide you through the process to ensure a smooth transition.
