VPS Hosting Assurance: Comparing PCI DSS, ISO 27001 and SOC 2 Evidence

When a customer asks for compliant VPS hosting, first clarify the evidence they need. PCI DSS, ISO/IEC 27001 and SOC 2 address different questions. They are not interchangeable badges, and a provider document does not automatically cover the customer’s application.

Match the evidence to the requirement

• PCI DSS: relevant to payment account data environments and applicable responsibilities. Outsourcing payment processing does not remove all merchant responsibilities; confirm scope with your acquirer or qualified adviser.
• ISO/IEC 27001: an information security management system standard. Check the scope of a claimed certification.
• SOC 2: an examination report about controls relevant to specified trust services criteria, not a universal product certification. Review the system, period, criteria and exceptions covered.

Start with the PCI SSC outsourcing guidance, ISO’s standard overview and AICPA’s SOC 2 resources. Have the relevant assurance professional interpret documents for your intended use.

Check that the evidence covers your actual service

Record the provider’s legal entity, the named service, locations and the applicable assessment date or period. Ask whether the proposed VPS platform and supporting operations are in scope. Identify exclusions, subcontractors and customer controls required by the evidence.

Do not replace this review with a screenshot of a logo. Where a report is restricted, agree an appropriate confidential review route with procurement or your assessor.

Document the boundary between provider and customer

• Who patches the guest operating system and applications?
• Who approves administrator access and reviews accounts?
• Which network controls are included and who changes them?
• Who configures logs, investigates alerts and retains evidence?
• Which backups are supplied, and who verifies application restoration?
• How are vulnerabilities, incidents and contract termination handled?

A VPS can be unmanaged, partly managed or supported under a more specific agreement. Confirm the tasks in writing rather than assuming that a managed label includes every compliance-related activity.

Prepare a scoped VPS enquiry

For QUAPE VPS hosting, provide your workload, payment or personal data flows and the evidence your customer requires. Request confirmation of available documents and service responsibilities before purchase. If dedicated physical resources are a requirement, evaluate dedicated hosting separately; physical isolation alone is still not proof of compliance.
