The CEO of "Precision Aero" (name changed to protect the unlucky) thought they were ready. They had the firewalls. They had the encrypted servers. They even had a shiny new tablet at the front desk where visitors typed in their names.
Then the auditor arrived.
He didn't ask for the server logs first. He walked to the front desk, pointed at the "Visitor Management" app, and asked one question:
"How do you verify that the 'John Smith' who signed in ten minutes ago isn't on the Consolidated Screening List?"
The Office Manager shrugged. "We check IDs."
The auditor smiled—the kind of smile that costs money. "Show me the time-stamped proof of that check against the federal database for every visitor in the last six months."
Silence.
