Frequently Asked Questions

How long does a PCI DSS audit take?

PCI DSS audit time ranges from 40 hours (SAQ-A for simple e-commerce) to 2,000+ hours (Level 1 ROC for large enterprises). The industry average across all assessment types is 1,142 hours annually including evidence collection, gap remediation, and QSA review time.

What takes the longest in a PCI audit?

Evidence collection accounts for 35–40% of total PCI audit effort on average. Organisations with manual evidence processes spend 487 additional hours per year compared to those with automated evidence collection.

How can I reduce PCI audit hours?

The three highest-impact reductions are: (1) automating evidence collection, saving 35–45% of audit hours; (2) implementing continuous monitoring, saving 22–30%; (3) using GRC-native remediation tracking, reducing closure cycles by 60%.

How many hours does a QSA need for a Level 1 ROC?

A Level 1 ROC typically requires 200–600 QSA hours for the assessment itself, plus 600–1,400 hours of internal organisation effort for evidence preparation, remediation, and stakeholder coordination. Total programmes often exceed 1,800 hours.

Does cloud infrastructure affect PCI audit hours?

Yes — cloud environments add 15–25% to audit effort due to shared responsibility model documentation requirements, cloud-native control evidence, and more complex network architecture diagrams. However, cloud-native continuous monitoring can offset this.
