TL;DR: Cardholder data protection depends on mapping people, systems, processes, and third parties to the cardholder data environment, with access control and segmentation doing most of the practical work, according to Zluri. That framing matters because scope drift is usually an identity and lifecycle failure, not just a network-design issue.
Editorial analysis by NHI Mgmt Group, based on content published by Zluri: “How to Define PCI DSS Scope for Your Organization?”.
Key questions
Q: What breaks when PCI DSS scope is not mapped to access and lifecycle controls?
A: The boundary becomes a paper exercise.
Q: When should organisations re-run a PCI DSS scoping review?
A: They should re-run it whenever a new application, vendor, workflow, or integration can change who can reach cardholder data or where it flows.
Q: What are the signs that PCI DSS scope is drifting?
A: Common signals include undocumented backup locations, broad admin access, unreviewed third-party connections, and systems that were declared out of scope but still connect to in-scope tools.
Practitioner guidance
- Map cardholder-data touchpoints across identity and infrastructure Document every person, process, application, backup, admin path, and third party that can store, process, transmit, or influence cardholder data.
- Re-certify access for connected-to-scope systems Include monitoring tools, backup servers, admin consoles, and service-provider accounts in recurring access reviews.
- Tie scoping reviews to change events Trigger a scope reassessment when new applications, integrations, vendors, or business processes are introduced.
Bottom line: PCI DSS scope is defined by the identities, systems, and third parties that can influence cardholder data, not by a single network control.

PCI DSS scope is an identity governance boundary, not just a network boundary. The article’s strongest point is that people, processes, systems, and third parties all contribute to whether cardholder data stays contained. That means scoping work belongs in IGA and access governance, not only in network engineering. Practitioners should treat PCI boundary design as a governance exercise with identity controls at the centre.
A question worth separating out:
Q: How should organisations use access reviews to support PCI DSS compliance?
A: Use access reviews to prove that only approved identities can reach cardholder data, and that revocation happens when access is no longer needed. The review process should include users, privileged accounts, and non-human identities, with remediation evidence stored alongside the decision so auditors can verify the full control path.
