Client Case Studies
Discover how we have partnered with ambitious UK enterprises to overcome complex technical challenges, secure their infrastructure, and accelerate their growth.
Consolidating Infrastructure to Achieve $750k/Month Savings
The Challenge
A globally distributed enterprise had accumulated massive technical debt and uncontrolled cloud sprawl across AWS, Azure, and GCP following multiple acquisitions, resulting in unpredictable billing spikes and a lack of unified security governance.
Our Solution
Dastute performed a comprehensive cloud audit and executed a massive consolidation strategy. We migrated disparate workloads into a unified, rightsized AWS environment, implementing automated FinOps policies and reserving instances for predictable workloads.
Key Outcomes:
- Achieved a verified $750,000 per month reduction in cloud operating expenses.
- Consolidated 400+ unmanaged cloud accounts into a secure, single-pane-of-glass AWS Organization.
- Implemented strict FinOps guardrails to prevent future cloud sprawl.
Cloud Migration & Data Sovereignty for a Private NHS Contractor
The Challenge
A leading private healthcare provider needed to migrate 15 years of legacy on-premise patient data to the cloud, while maintaining absolute compliance with NHS Data Security and Protection Toolkit (DSPT) standards.
Our Solution
Dastute engineered a secure, HIPAA/DSPT-compliant Azure environment utilizing advanced encryption-at-rest and strict Role-Based Access Control (RBAC). We executed a zero-downtime 'lift and reshape' migration over a single weekend.
Key Outcomes:
- 100% compliance with NHS data sovereignty requirements.
- 40% reduction in monthly infrastructure operating costs via Azure Hybrid Benefit.
- Zero downtime experienced by medical staff during the migration window.
Zero Trust Architecture for an FCA-Regulated Payment Gateway
The Challenge
A rapidly scaling payment processor required a comprehensive cybersecurity overhaul to achieve SOC 2 Type II compliance and satisfy stringent FCA regulatory audits before launching their new B2B product.
Our Solution
We implemented a complete Zero Trust Architecture (ZTA) across their AWS environment. This included mandatory multi-factor authentication (MFA) via hardware keys, network micro-segmentation, and an automated Endpoint Detection and Response (EDR) rollout to 150+ employee laptops.
Key Outcomes:
- Achieved SOC 2 Type II certification with zero non-conformities.
- Passed FCA technical audit on the first attempt.
- Reduced Mean Time to Detect (MTTD) threats from hours to seconds.
Automating Global Supply Chains with Hyperledger Fabric
The Challenge
A multinational automotive parts manufacturer suffered from massive supply chain disputes, with reconciling invoices and tracking lost shipments across 5 different international distributors taking an average of 14 days.
Our Solution
Dastute developed a private, permissioned blockchain network using Hyperledger Fabric. We integrated IoT sensors into shipping containers that automatically wrote location and temperature data to the immutable ledger, triggering smart contracts for instant payment settlements.
Key Outcomes:
- Reduced invoice reconciliation time from 14 days to real-time.
- Eliminated 98% of fraudulent or disputed shipping claims.
- Provided total, auditable track-and-trace visibility to the end consumer.
Scaling Engineering Capacity with IT Staff Augmentation
The Challenge
A major UK e-commerce brand needed to completely rebuild their legacy monolithic frontend into a modern React application before the Q4 holiday rush, but could not source enough senior talent locally.
Our Solution
Dastute instantly augmented their internal engineering team with 4 Senior React Developers and 1 Cloud QA Engineer. The augmented team integrated seamlessly into the client's Agile sprints within 48 hours.
Key Outcomes:
- Successfully launched the new platform 3 weeks ahead of the Black Friday deadline.
- Increased mobile conversion rates by 22% due to improved page load speeds.
- Client seamlessly scaled down the augmented team post-launch without redundancy costs.
