When Legacy Tools Hits Its Limits

Across the UK public sector, digital transformation is accelerating at an unprecedented pace. From defence and national security to citizen-facing critical services, organisations are under pressure to modernise legacy systems while maintaining the highest possible levels of security, resilience, and compliance.

One major UK government services and critical-infrastructure provider recently undertook one of the most ambitious programmes in its history: migrating its entire data-centre estate into a UK sovereign cloud environment in just 18 months. With national-level services on the line, failure wasn’t an option.

What they needed was a new approach to cyber resilience—one designed for the cloud, capable of keeping pace with the scale and sensitivity of their mission.

This is where Elastio came in.

The Challenge: Legacy Tools Weren’t Built for the Cloud

Before their migration, the organisation used a combination of on-premises storage and specialist forensics tools to scan, validate, and protect backups from ransomware and corruption. These tools had served them well for years, but they were built for static data-centre environments—not for modern cloud scale.

When the team attempted to lift-and-shift their scanning cluster into the cloud, two problems became immediately clear:

• Performance bottlenecks made cloud-scale validation impractical
• Costs spiked dramatically, making the model unsustainable
• Architecture mismatches meant legacy tools simply couldn’t operate effectively in a sovereign cloud environment

To support the migration timeline, they needed a cloud-native way to ensure every backup was clean, recoverable, and compliant—without introducing delays or risk.

The Solution: Cloud-Native Cyber Resilience with Elastio

Elastio partnered with the organisation’s cloud and infrastructure teams early in the programme to help redesign their approach to backup integrity and ransomware detection. Built natively on AWS technologies and designed specifically for large-scale, regulated workloads, Elastio offered several key advantages:

Cloud-native backup integrity validation

Elastio delivers automated, high-performance scanning of backups using cloud-native services—no clusters to maintain, no legacy overhead.

Full support for Rubrik

The customer selected Rubrik as its backup solution for cloud, and Elastio integrates seamlessly with Rubrik’s native architecture.

Compatibility with all major backup platforms

Including AWS Backup, Veeam, Cohesity, Commvault, and NetBackup—ensuring flexibility as environments evolve.

A private, sovereign deployment model

Perhaps most importantly for this project, Elastio can operate entirely within the customer’s own secure, sovereign cloud environment—meeting strict UK public-sector compliance and data-isolation requirements.

The result is a cyber-resilience architecture built for cloud scale, cloud speed, and cloud compliance.

The Outcome: Increased Confidence, Reduced Risk, and a Faster Migration

With Elastio in place, the organisation now validates every backup for ransomware and corruption, automatically and at scale. This provides assurance that:

• Backups are clean and trustworthy
• Recoveries will work when they’re needed most
• Sensitive workloads remain protected inside sovereign boundaries
• The cloud migration can proceed without introducing new cyber risks

Elastio now plays a critical role in safeguarding the organisation’s sovereign cloud environment—supporting operational continuity, reducing cyber risk, and enabling a faster and more confident migration.

A Win for UK Public-Sector Cloud Transformation

This success story underscores the power of modern, cloud-native cyber resilience. As public-sector organisations continue moving into UK sovereign cloud environments, the need for scalable, automated protection against ransomware and data corruption has never been more important.

Elastio is proud to partner with UK government and critical-infrastructure organisations as they undertake major cloud transformation programmes—helping them migrate faster, operate more securely, and meet the high bar of resilience required for national-level services.
