Struggling Banks and Insurance Firms Face Outdated Infrastructure - Immediate Need for Modernisation
Modernizing Network Architectures in the Financial Sector
In the rapidly evolving digital landscape, financial institutions are grappling with the challenges of modernizing their network architectures to keep pace with innovation and maintain a competitive edge. A study conducted by techconsult GmbH in November 2024, titled "Future-proof Networks for Business," revealed some intriguing insights into this critical issue.
The digitalization of the financial sector is putting IT infrastructure to the test, particularly wide area networks (WANs). According to the study, 57% of IT managers in the financial sector view outdated WAN architectures as a significant challenge. Financial institutions rely on stable and high-performance networks due to sensitive data and business-critical real-time transactions.
Current trends in network architecture for financial institutions center on achieving high performance, scalability, flexibility, and fault tolerance to meet the intensive demands of digital transformation and mission-critical operations. Among these trends, hybrid network topologies and Software-Defined WAN (SD-WAN) technologies play pivotal roles.
Hybrid Network Topologies
Financial institutions deploy hybrid topologies combining elements of star, mesh, bus, or tree networks to leverage the strengths of each. Hybrid topologies provide outstanding efficiency, high availability, flexibility, and fault tolerance, essential for large, complex networks that demand reliability and scalability.
However, designing, implementing, and troubleshooting hybrid networks is complicated due to the integration of multiple topologies. Installation and maintenance can be expensive because specialized hardware and intelligent hubs are often required. While hybrid topologies are scalable, managing growth and ensuring seamless integration of new components increase administrative complexity.
Software-Defined WAN (SD-WAN)
SD-WAN technology is transforming how financial institutions manage WAN connectivity. SD-WAN decouples networking hardware from control mechanisms, enabling centralized, policy-driven management.
SD-WAN enhances network agility, security, and flexibility, automatically routing traffic based on real-time conditions and business policies. It supports compliant, secure digital banking operations by integrating cloud services and enabling hybrid cloud connectivity. SD-WAN helps reduce operational costs compared to traditional WANs by utilizing commodity internet links alongside MPLS. SD-WAN facilitates faster adoption of cloud-based services and accelerates innovation in financial services.
Impact on Digital Transformation
Hybrid network topologies enable financial institutions to build robust, fault-tolerant infrastructures critical for continuous uptime, especially in trading, core banking, and payment processing systems where downtime is costly. SD-WAN complements hybrid topologies by providing centralized control, dynamic path selection, and enhanced security across distributed branches and cloud environments, thus accelerating cloud migration and digital service delivery.
Hybrid cloud deployments combined with SD-WAN (e.g., EdgeVerve’s digital banking on managed hybrid cloud platforms) support scalable, secure, and compliant banking solutions, helping banks innovate rapidly while maintaining rigorous standards.
In summary, hybrid network topologies empower financial institutions with resilient and scalable physical infrastructures necessary for critical operations, while SD-WAN technologies enhance network agility, security, and centralized control, enabling rapid digital transformation through better cloud integration and cost efficiency. The combination is increasingly vital for financial institutions aiming to innovate securely and efficiently in a competitive digital landscape.
The study "Future-proof Networks for Business" finds that many financial companies still use historically grown structures that no longer meet current requirements. The shift towards hybrid work models presents a new challenge for network design in banks and insurers, with 43% of companies seeing this as a specific challenge for their network strategy.
Frank Rosenberger, CEO of 1&1 Versatel, is quoted in the study, emphasizing the strategic importance of networks in the financial sector. "Networks in the financial sector are a strategic resource," he said. "High performance and the highest security standards are key factors for success in digital competition."
