Cygnet.One Modernizes Core Insurance Platform for South Africa’s The Unlimited

Cygnet.One has completed a multi-year modernization of The Unlimited’s core insurance platform, shifting the South African provider to a cloud-native architecture on Microsoft Azure. For insurance technology leaders, this demonstrates the practical execution of phased legacy migration in high-volume markets, balancing continuous operations with the transition to microservices and automated digital workflows to better serve over three million policyholders.

What was announced

The collaboration between Cygnet.One and The Unlimited has transitioned into a comprehensive modernization of the insurer’s core platform, moving from legacy structures to a cloud-native, microservices-based architecture. This multi-year engagement, which initially began with mobile development, has expanded to encompass machine learning, business intelligence, and the integration of Microsoft Dynamics 365. The project specifically targeted the operational needs of The Unlimited, which provides insurance coverage to more than three million people in South Africa.

The technical implementation utilized a phased approach to ensure business continuity. By running the existing and new systems side by side, the engineering teams maintained reliable data movement throughout the transition. The final architecture leverages Azure Kubernetes Service (AKS) for hosting independent microservices, while Azure Application Gateway manages routing and authentication. For asynchronous communication between services, the platform employs RabbitMQ.

Operational visibility is maintained through Azure Monitor and Application Insights, providing centralized logging for system health. A key functional improvement includes the ability for field and sales teams to capture policy information without an active internet connection, synchronizing data automatically once connectivity is restored. This shift from manual, paper-based processes to digital workflows is designed to support the company’s capacity for customer growth and faster response times to market requirements. The two organizations continue to develop new requirements on this shared architecture.

"Technology should enable the business rather than constrain it. Modernising our core platform has given us a foundation that can scale with our growth, support new digital experiences and allow us to respond more quickly to changing customer and business requirements,"

Sean Peatt, CIO, The Unlimited.

The companies involved

The Unlimited is a prominent South African insurance provider that has established a significant footprint in the region, currently serving a customer base of over three million individuals. Based in South Africa and operating via its primary portal at theunlimited.co.za, the company focuses on delivering accessible insurance products. Its operational model relies heavily on field sales and digital engagement, making the reliability of its core technology infrastructure a critical component of its market position.

Cygnet.One, the technology partner behind the modernization, provides engineering and digital transformation services with a focus on cloud-native architectures. The firm, which operates the domain cygnet.one, specializes in scaling enterprise platforms through the application of microservices and integrated business intelligence tools. In this partnership, Cygnet.One acted as the primary architect for the migration to Microsoft Azure, moving the insurer away from constrained legacy systems. The relationship between the two entities has evolved from specific mobile application projects into a broad-spectrum technology collaboration covering core insurance operations and data management.

What this means from an insurtech perspective

This transition from paper-based processes to a microservices architecture on Azure signals a shift for carriers operating in emerging markets. By integrating machine learning and business intelligence into the core, the project moves the needle on data-driven underwriting and pricing. For MGAs and brokers, the offline synchronization capability directly addresses distribution bottlenecks in regions with intermittent connectivity, ensuring field teams remain productive. However, the reliance on a phased, side-by-side migration raises questions for the wider industry regarding the total cost of ownership during long-term parallel runs. As legacy core-system modernization becomes a prerequisite for scale, the pressure intensifies on incumbent vendors to provide the interoperability required for such complex, cloud-native transformations.
