Shared hosting providers must protect each entity's hosted environment and cardholder data and meet Appendix A: Additional PCI DSS Requirements for Shared Hosting Providers. Which option correctly reflects this obligation?

• A. They must protect each entity's hosted environment and cardholder data, and meet Appendix A: Additional PCI DSS Requirements for Shared Hosting Providers.
• B. They only need to protect the hosted environment, not cardholder data.
• C. They must meet PCI DSS only for their own data, not hosted environments.
• D. They may transfer responsibility to the client.

Answer: (A)

In shared hosting, the provider’s role is to safeguard every client's hosted environment as well as the cardholder data passing through that environment, and to comply with Appendix A: Additional PCI DSS Requirements for Shared Hosting Providers. This reflects the reality that multiple clients’ data may be on the same infrastructure, so strong separation, access controls, encryption where appropriate, and ongoing monitoring are essential to prevent cross-contamination and unauthorized access. Appendix A explains the extra steps and safeguards necessary in this setup, beyond the standard PCI DSS requirements, to ensure that the hosting platform itself doesn’t become a risk to any one client’s data. Other options fall short because they imply protecting only part of the scope or shifting responsibility away from the provider. Limiting protection to the hosted environment without safeguarding cardholder data ignores the data that resides and transmits through that environment. Limiting PCI DSS to the provider’s own data fails to address the data processed for clients. And shifting responsibility entirely to the client contradicts the shared hosting model and Appendix A’s emphasis on the provider’s accountability and the need for clear, defined responsibilities in agreements.
