A1.1.2 Customers limited to their own cardholder data and CDE
The provider must implement controls ensuring every customer is permitted to access only its own cardholder data and its own cardholder data environment (CDE), never another tenant's. Guidance example: in an IaaS-style offering the customer CDE may include virtual servers, virtual network devices, operating systems, files and memory that the customer configures and manages itself. Applies to multi-tenant service providers. Customized approach objective: one customer is unable to reach any other customer's environment.
Source: PCI DSS v4.0.1, A1.1.2. The statement above is our statement of the clause, read from the published text and cited so you can check it against the official text, not the instrument verbatim. Open PCI DSS v4.0.1 in the compliance library.
Version 4.0.1 is the active version; 4.0 has been retired. Appendix A1 applies only to multi-tenant service providers, A2 only to card-present POS POI terminals that still use SSL or early TLS, and A3 only when a payment brand or acquirer requires it. Which requirements apply to you follows your validation type.
These are the artefacts auditors commonly ask for on this requirement, our guidance rather than text from the standard. Your assessor decides what is sufficient in your context, and asks for samples across the period when a report covers one.

Common gaps auditors find
- Shared database schema relies only on application logic for tenant filtering
- Wildcard IAM roles grant one tenant visibility of another tenant's storage buckets
- Documentation defines tenant isolation but configurations were never checked against it
