Financial services AI is moving from the back office to the front lines, with 32% to 39% of work across capital markets, insurance, and banking poised for full automation1. However, as institutions race to deploy generative AI and autonomous agents, they are colliding with a physical wall: their legacy network infrastructure. These new workloads fundamentally reshape WAN requirements, driving massive traffic across distributed locations where strict latency and predictability are critical. Traditional networks simply were not designed to handle data moving at this scale between AI clusters, clouds, branches, and the edge.
Consider an ordinary Tuesday morning at a modern, global financial institution. In Singapore, a fraud model flags an unusual wire and routes it for human review, but the alert takes eleven seconds to reach the analyst's queue from the AI cluster in the primary data center. By the time she opens the case, the payment has cleared. In London, an underwriter waits on a model that ingests satellite and aerial imagery for commercial property renewal; the file times out twice before the risk score returns, and the broker calls back before she can quote. In New York, a quant team's overnight backtest finishes ahead of schedule, then sits idle for forty minutes while the results copy across a saturated link to the research environment. All these problems demonstrate that an AI-powered process can only be as fast as its slowest component, and only as secure as its least secure component.
Financial organizations are not just consuming cloud-based AI; 68% of enterprises favor training and customizing their own private AI models 2 .
