In the financial world, trust isn’t just a value; it’s a necessity. It’s built on secure data, resilient systems, and deep industry insight. At TGV, we bring all three to the table. With decades of experience supporting banks, insurance companies, and payments processing companies, we deliver solutions that combine business intelligence, rock-solid technology, and a long-term perspective.
The financial industry demands performance, reliability, and regulatory compliance, but it also requires the agility to adapt in a constantly evolving market. At TGV, our Financial Services team develops solutions that not only keep operations stable but also support a gradual, well-managed, and sustainable path toward technology transformation.
Yes, many financial institutions still rely on legacy platforms like Mainframe and AS/400, and that’s perfectly valid. These systems are proven workhorses. But we go beyond just keeping them running. We help modernize them by integrating new technologies that improve performance while protecting the strengths that are already in place.
Here are three areas where legacy platforms continue to give financial institutions a competitive edge:
✔️ Built-in Security and Transaction Control
Mainframe and AS/400 systems were built for high-stakes environments. Their transactional architecture ensures that every operation is atomic, consistent, isolated, and durable (ACID), which makes them especially valuable in banking processes where mistakes are simply not an option. These systems also provide strong layers of access control, traceability, and auditing, ─critical in a landscape of increasing regulation and more sophisticated threats.
✔️ High-Volume Processing with Minimal Latency
Many banks still rely on these platforms as the core of their daily operations. The reason is simple: they are unmatched when it comes to real-time, high-volume processing, handling millions of transactions simultaneously, and maintaining fault tolerance. Whether it’s bank clearing, settlements, accounting close, or overnight batch processing, these systems are built to avoid bottlenecks. Their consistent and predictable performance is a strategic asset.
✔️ Adaptability Without Disruption
Despite common belief, these environments are not static. Through development in RPG or COBOL, and by exposing APIs through middleware layers, they can be integrated with modern systems. This includes mobile applications, digital onboarding platforms, compliance tools, and analytics engines. The key is to approach integration with technical discipline, minimizing operational risk and aligning with the financial sector’s pace and requirements.
At TGV, we don’t just know these systems, we work in them every day. We know when to modernize, when to maintain, and how to create real connections between what works today and what comes next. That’s how we help financial institutions move forward with confidence. We bring deep experience, operational precision, and a clear understanding of what’s on the line every time a transaction hits the system.
