From Legacy to Cloud: Synthesis Architects the Digital Core of Modern Banking

In an era, where digital transformation is reshaping every facet of the financial services industry, Synthesis has emerged as a pivotal force, enabling banks to evolve with agility, security, and innovation. With over two decades of experience, Synthesis has strategically aligned its solutions across cryptography, cloud, data, payments, RegTech,  digital transformation, and SoftPOS to meet the ever-changing demands of modern banking.

As cyber threats grow in complexity alongside technological advancement, Synthesis leads the charge in securing the digital financial landscape.By leveraging Thales Payshield hardware security modules (HSMs), the industry benchmark for payment protection, the company ensures that sensitive financial data remains secure and compliant with PCI standards. Their Keystone solution abstracts the complexity of cryptography, enabling developers to manage secure PINs with ease. Looking ahead, Synthesis is already preparing for the quantum computing era, investing in post-quantum cryptography and crypto agility to future-proof banking infrastructure.

This commitment to security seamlessly extends into the cloud, where Synthesis empowers banks to scale with confidence. Their cloud-native architectures, built on platforms such as AWS, Google Cloud and Kubernetes, support real-time data flow, automated alerts, and resilient disaster recovery. By aligning with regulatory frameworks such as PCI DSS, POPIA, and GDPR, Synthesis ensures that cloud adoption enhances data sovereignty and security. Their successful implementations with BankservAfrica and the Top Tier Banks demonstrate their ability to deliver robust, scalable solutions tailored to the financial sector.

By combining advanced analytics, AI, and cloud-native data engineering, the team helps banks harness the power of their data through smarter decision-making, real-time insights, and operational efficiency. Intelligent data solutions, ranging from modern data platforms to machine learning for fraud detection, are built with a deep understanding of financial services and compliance.

This innovation extends into RegTech, where Synthesis transforms regulatory compliance from a burden into a strategic advantage. Their suite of tools, including TXstream and the FinSurv Suite, automates data ingestion, validation, and submission across jurisdictions, supporting compliance with SARS, HMRC, IRS, and SARB. With features such as real-time rule validation, centralised dashboards, and AI-enhanced anomaly detection, Synthesis enables banks to meet complex regulatory demands with precision and agility. Success stories from three popular banks in South Africa highlight the scalability and reliability of these solutions.

At the heart of this transformation is the modernisation of payments infrastructure. Synthesis has developed modular, API-driven platforms that support ISO 20022 and real-time processing, reducing operational overhead and enabling instant transaction visibility. Security is embedded at every layer, from cloud-native services to PCI compliance. Their collaboration with a well-known bank on PayShap, achieving sub-5-second transaction times, exemplifies their dedication to both speed and security. As the industry shifts toward tokenisation, invisible payments, and AI-driven analytics, Synthesis continues to innovate, ensuring banks stay ahead of the curve.

Completing this digital transformation journey is Halo Dot, Synthesis’s SoftPOS solution that redefines in-person payments. By turning smartphones into secure payment terminals, Halo Dot eliminates the need for traditional hardware, aligning with sustainability goals and accelerating merchant onboarding. Certified against PCI MPoC and PCI DSS 4.0, it offers features such as attestation monitoring, digital wallet support, and offline capabilities, making it ideal for high-volume sectors such as retail, transit, and events. The upcoming Halo Dot Adaptor will give banks full control over their SoftPOS infrastructure, enhancing both autonomy and operational efficiency.

Synthesis’s evolution mirrors the broader transformation of the banking industry. From cryptographic resilience and cloud scalability to real-time payments and intelligent data compliance, their solutions are designed not just to meet today’s challenges, but to anticipate tomorrow’s.

As trends like AI-driven fraud detection, omnichannel payments, and programmable finance gain momentum, Synthesis remains a trusted partner for banks navigating the digital frontier. Their holistic approach, grounded in deep industry knowledge and a commitment to innovation, ensures that banks are not only compliant and secure but also agile and future ready.
