Finsure, a leading Australian mortgage aggregation group, supports a network of 4,000 brokers and manages a loan book exceeding $179 billion. As the company scaled to facilitate one in nine new home loans in Australia, the limitations of legacy on-premises infrastructure became a strategic risk. By partnering with Mantel for a full-scale AWS migration and ongoing Managed Services, Finsure successfully transitioned its mission-critical Infynity CRM to a cloud-native environment.

At a glance
Key outcomes
- 99.18% uptime across 68 million monthly requests.

The challenge
Finsure’s primary value proposition is its proprietary technology. To maintain a competitive edge in a high-growth FinTech sector, the executive team required an infrastructure capable of supporting rapid expansion while managing operational risk. The legacy environment faced three primary hurdles:
- Dynamic scalability: The platform needed to process multi-billion dollar monthly loan lodgments without performance degradation.
- Regulatory compliance: As a major financial intermediary, Finsure must meet rigorous industry standards for data security and operational resilience.
- Legacy risk: Technical debt threatened to impede long-term digital transformation.
The solution: a strategic partnership with Mantel
Finsure engaged Mantel to design, migrate, and manage a high-availability AWS architecture tailored for the Australian and New Zealand markets. This move replaced capital-heavy legacy systems with a flexible, consumption-based model, underpinned by expert oversight.
Ongoing Managed Services and support
Rather than a “set and forget” migration, Mantel provides a 24/7 Managed Service to ensure the Infynity application remains “always-on”. This partnership focuses on three key areas:
- Proactive observability: Implementation of comprehensive monitoring across the AWS ecosystem and data pipelines to identify and resolve potential issues before they impact the broker network.
- Security governance: Continuous Cloud Security Posture Management (CSPM) using Plerion, with Mantel providing proactive recommendations to improve Finsure’s security score and compliance standing.
- Technical debt reduction: Ongoing efforts to modernise infrastructure and the transition to automated certificate handling.
The results: commercial and operational impact
The partnership moved Finsure from a reactive cost centre to a proactive, data-driven operation, including a continuous cost management and improvement process that ensures Finsure gets the best value from its hosting spend.
”Mantel gives us complete peace of mind that our AWS infrastructure is resilient, scalable, and fully managed. They aren't just an external vendor; they are a strategic technical partner enabling our growth and acceleration.

Strategic lessons
- Continuous optimisation: Cloud efficiency is an ongoing process. Mantel’s Managed Services actively manage resource utilisation to ensure Finsure gets maximum value from its cloud investment quarter on quarter.
- Expert oversight as a force multiplier: By offloading 24/7 operational management to Mantel, Finsure’s internal teams can focus exclusively on high-value software development and market expansion.
- Compliance by design: Establishing security baselines before migrating workloads ensured Finsure met industry regulatory requirements from day one, significantly reducing the audit and compliance burden.
Conclusion
Through this strategic partnership with Mantel, Finsure has successfully decoupled its business growth from infrastructure constraints. With a robust, managed deployment pipeline and a continual improvement model for cloud spend, the group has the financial flexibility and technical agility required to lead the Australian mortgage market.
