Case Study
One of the UK’s Largest Insurers Migrates to Splunk Cloud to Support Net-Zero Goals and Drive Observability at Scale
Case Study Introduction
Customer Summary
A leading multinational insurance company, headquartered in the UK, serves more than 33 million customers globally and employs over 29,000 people. With a growing focus on digital transformation and sustainability, the organisation set out to modernise its observability capabilities and reduce operational overheads.
To meet internal service demand, the insurer required a robust and scalable monitoring solution that could support hundreds of business users while aligning with broader corporate targets – including their net-zero ambitions.
Customer Testimonial
Business Challenges
The insurer’s operations team supported over 1,400 internal users across numerous business-critical functions but spent a disproportionate amount of time managing infrastructure, coordinating upgrades, and handling administrative tasks. This operational overhead limited their capacity to focus on delivering strategic value and responding proactively to incidents. At the same time, increasing demand for timely and reliable insights exposed visibility gaps across a complex IT estate, creating risks to performance and availability.
Compounding these challenges was an aggressive project timeline that required a seamless migration to a cloud-based observability platform. The solution had to be delivered without disrupting ongoing operations or losing critical monitoring capabilities, while also providing scalability and resilience to support the organisation’s broader net-zero and digital transformation goals.
Requirements
To support a successful transition, the insurer had the following technical and operational requirements:
Migration from existing Splunk App Monitoring to a fully managed Splunk Cloud SaaS environment
End-to-end visibility of customer-facing applications and infrastructure
Dashboards and analytics to support over 700 business users
Platform scalability to accommodate 1.5TB daily ingest and high-volume search queries
Automated alerting, trend analysis and system health monitoring
A trusted partner capable of delivering at speed and scale
