When you’re operating with just five payment pages, PCI feels predictable. Not because controls are simple, but because the variables are contained. It’s simple math. You know the pages. You know the scripts. You know how often they change and who owns each one. So the environment is small enough that nothing surprises you, and predictability becomes the default. But then, your organization grows. New products, regional variants, A/B experiments, and acquisitions all add up.
