Nothing calms an audit like evidence that isn’t improvised.

Architecture everyone remembers differently
Ask three people how card data moves through the system and you’ll get three answers, which is exactly how scope balloons and audit conversations spiral.
Evidence that exists… just not in one place
Diagrams live in old decks, risk decisions live in Slack, and PCI documentation lives somewhere else entirely, making simple auditor questions take days to answer.
Controls that work but are hard to explain
Security controls exist for good reasons, but without design context they look arbitrary on paper and turn “this is secure” into a debate.
PCI-DSS scope that keeps quietly growing
Unclear data flows and undocumented integrations pull more systems into scope every year, whether they deserve to be there or not.
Design decisions that were never written down
Risk calls made during fast-moving builds now have to be reconstructed under pressure, usually by people who weren’t in the room at the time.
Engineering teams getting pulled in too late
When PCI questions show up during audit week, engineers lose time explaining past work instead of shipping new features, and everyone feels it.
