CIMB Bank: Keeping Asia’s Financial Heartbeat Strong with Nagios XI

Introduction: The Challenge of Uninterrupted IT in the Dynamic World of Finance

In the relentlessly competitive and highly regulated world of finance, uninterrupted IT operations are not just desirable – they are absolutely essential. CIMB Bank, a leading ASEAN bank with a substantial and growing presence across Southeast Asia, understands this fundamental truth. Serving millions of customers who rely on their services for everything from everyday transactions to complex financial instruments, CIMB needed a robust, reliable, and scalable monitoring solution to guarantee the constant availability and optimal performance of their mission-critical IT infrastructure.
