PCI Compliance Risk Index

Fragmented POS estate, manual patching cycles

Legacy property management systems, high staff turnover

Third-party dependency risk, tokenisation gaps

Complex network topology, evidence collection lag

Strong controls baseline, regulatory overlap burden

Cloud-native architectures, scope reduction potential

Highest automation rates, proactive gap remediation

Delayed OS and application patching remains the single most common audit finding across all industries (Req 6.3).

Insufficient segmentation between CHD environments and general corporate networks — particularly critical in Retail and Hospitality.

Shared credentials, excessive privilege, and delayed access revocation drive recurring findings under Req 7 and Req 8.

Missing or stale evidence for continuous controls — especially vulnerability scans, log reviews, and security awareness records (Req 10, 12).

What does the PCI Compliance Risk Index measure?

The Risk Index is a composite score (0–100, lower = lower risk) derived from four risk dimensions: patch management adherence, network segmentation strength, access control maturity, and evidence collection completeness. Scores are weighted by PCI DSS requirement severity and normalised within each industry cohort.

Why does Retail have the highest risk score?

Retail organisations typically operate fragmented POS estates with heterogeneous hardware running varied OS versions, making systematic patching difficult. Combined with high staff turnover affecting access control hygiene and large cardholder data environments, the structural risk profile is materially higher than cloud-native industries like SaaS or FinTech.

How can my organisation reduce its risk score?

The most impactful interventions target the top two drivers: automated patch management workflows (typically reducing risk score by 8–12 points) and network segmentation reviews with microsegmentation tooling (5–9 points). GRCTrack's continuous monitoring surfaces these gaps in real time, enabling proactive remediation rather than reactive audit findings.

Is the Risk Index the same as a maturity score?

No — they measure complementary dimensions. The Maturity Score reflects the sophistication and consistency of your compliance programme. The Risk Index reflects residual exposure from gaps and weaknesses. An organisation can have a moderate maturity score but a high risk score if specific high-severity controls are weak. Both metrics together provide a complete picture.
