Trading
Trading businesses run lean — every system that's down is a transaction that doesn't happen. Email reliability, ERP connectivity, and payment infrastructure form a critical path that most trading companies have assembled from multiple vendors over multiple years, often without anyone ever auditing the interdependencies.
The specific risk profile in trading is high-frequency, high-cost operational interruption combined with concentrated exposure to single-vendor failures. We've seen companies lose significant revenue not because of a cyberattack but because two aging Exchange servers shared a single point of failure that nobody had documented.
A trading company with thirty-five staff had been operating with fragmented infrastructure across three vendors and two generations of Exchange servers — the kind of setup that works until it doesn't. The migration to a consolidated M365 environment, done over a planned weekend without business interruption, took four months of preparation. The preparation was the work.
