How a Major Bank Achieved 99.9% Uptime Across 300+ Branches with Multi-WAN Bonding and VPN

In today’s digital-first financial landscape, branch connectivity is more than just an IT function—it’s a lifeline. When networks go down, customer trust, service delivery, and revenue are all at risk.

A leading financial institution operating in West Africa faced the daunting task of delivering reliable, high-speed internet connectivity to over 300 branches, many located in remote areas with unreliable infrastructure. The bank also needed to secure communication between its headquarters and branches using VPN, while maintaining consistent performance across all locations.

The Challenge: Reliable Branch Connectivity in Infrastructure-Limited Areas

The bank’s key connectivity requirements included:

  • Always-on internet for 300+ branches
  • Secure VPN tunnels between HQ and each remote site
  • Support for multiple types of internet connections: 4G/3G, satellite, and fixed-line
  • Centralized network management and automated failover
  • Efficient routing of internal traffic between HQ and branches

Traditional MPLS or single-line ISP solutions weren’t cutting it. Service disruptions, slow failover times, and routing complexities led to inconsistent performance and high operational overhead.

The Solution: comBOX Multi-WAN Bonding with Integrated VPN & Smart Routing

The bank selected comBOX VLL (Virtual Leased Line)—a powerful solution that provides:

Multi-WAN bonding, aggregating bandwidth from cellular, satellite, and fixed-line connections into a high-throughput virtual connection at each branch
Transparent failover, ensuring sessions remain active even during network outages
Integrated VPN services between headquarters and all branch offices, providing end-to-end encryption and secure access
Intelligent routing, eliminating the need for third-party routing appliances and simplifying network architecture
24/7 centralized monitoring, enabling proactive support and full visibility
