Frequently Asked Questions
What is the scope of a PCI penetration test for a large financial institution?
Large financial institutions have the broadest PCI pen test scope of any sector: payment card systems, internet banking application layers, internal network segmentation across thousands of systems, core banking API security, ATM network security, and third-party fintech integration points. Engagements typically run 3–6 weeks for tier-1 banks.
How do financial institutions manage PCI pen testing alongside regulatory requirements?
Financial Services organisations often align PCI penetration testing with CBEST, TIBER-EU, or other threat-intelligence-led pen test frameworks required by banking supervisors. A single engagement designed to meet both regulatory and PCI requirements reduces total testing cost and disruption.
What is the average engagement duration for Financial Services PCI penetration tests?
Financial Services averages 14–21 day engagements for PCI penetration testing — the longest of any sector, reflecting the broadest CDE scope and most complex network environments. Tier-1 institutions with dedicated security testing teams often run continuous pen test programmes rather than point-in-time annual engagements.
