Nation-state operations
Some adversaries have time, budget and patience that commercial defences are not designed around.
They will spend months, use techniques nobody has seen, and accept a slow approach because there is no quarterly target. For most organisations this is not the relevant threat and being treated as if it were produces wasted spending. For a small number it is, and the honest answer there is usually about detection and resilience rather than prevention.
