What Is Payments Compliance?

Payments Compliance is the process of meeting the security standards and regulatory requirements that apply to the processing, storage and transmission of payment information.

For organisations handling payment card data, PCI DSS is one of the most important global security standards. Depending on the organisation and payment environment, additional PCI standards or regulatory requirements may also apply.

Integrity360 helps organisations understand their obligations, reduce unnecessary compliance scope, implement appropriate controls and demonstrate compliance through the required assessment and validation processes.

Why Payments Compliance Matters

Payment environments are a high-value target for cybercriminals, and compliance requirements continue to evolve alongside changes in technology and threat activity.

Effective payments compliance helps organisations:

  • protect cardholder and payment data
  • reduce security gaps across the payment environment
  • meet contractual and industry requirements
  • provide evidence that controls are operating effectively
  • reduce the complexity of annual assessments
  • strengthen customer and partner confidence

PCI DSS should also be treated as an ongoing security programme rather than a once-a-year assessment exercise.

Our services

  • Gap assessments – Map card data flows, reduce scope, save time.

  • Testing & validation – Pen testing, vulnerability scans, ASV services.

  • Remediation support – Fix issues and optimise controls.

  • Audit & attestation – QSA coordination and audit readiness.

  • Continuous compliance – Dashboards, monitoring, alerts.
