The Challenge
Global Trust Bank faced critical challenges in its core banking transformation journey.
Outdated Core Banking Systems
The bank's core banking platform was running on legacy mainframe systems implemented in the early 2000s. This aging infrastructure created significant performance bottlenecks, made integration with modern fintech solutions challenging, and limited the bank's ability to launch innovative products quickly.
Regulatory Compliance Complexity
As a systemically important financial institution, Global Trust Bank needed to comply with stringent RBI regulations, including data localization requirements, VAPT guidelines, and the RBI's Cyber Security Framework. Modernizing core systems while ensuring continuous compliance presented a significant challenge.
Business Continuity Risks
With millions of daily transactions processing through the core banking system, the bank could not afford any downtime during the migration. The transformation needed to be executed while maintaining 24x7 operations and ensuring that customer services remained uninterrupted.
"Our legacy core banking system had become a significant constraint on our business agility. Adding new features or products took months instead of weeks. Meanwhile, our customers were increasingly comparing our digital experience not just to other banks but to the best digital experiences they had anywhere. We needed to modernize our core systems without disrupting our operations or compromising on security and compliance."
