Although you are correct in that it doesn't state a blind test. The
sample environment you are required to scan for certification is a
remote environment which precludes an onsite visit and normal data
information gathering phases that would be performed during a full
security assessment.
PCI testing is narrow in scope and specific in its requirements. I am
simply trying to determine what others are doing to meet the minimum
requirements to perform a PCI scan under the industry requirements.
Please do not confuse this with a PCI audit which is a much larger
undertaking and more closely matches a "full on" security assessment.

The issue is to ensure that the site is configured to a statndard and that all KNOWN vulnerabilities are patched/mitigated. VISA does not want to test the site as iut may be seen from the internet by hackers, this is just wrong for all those who believe this.
