Australia’s privacy landscape

Payment security is more than a checkbox. It’s a foundation for business trust and understanding how to protect cardholder data and prevent fraud is essential. The Payment Card Industry Data Security Standard (PCI DSS) offers a clear framework to help businesses secure transactions and meet compliance requirements¹.

 

What strong payment security delivers

 

What to prioritise in your security setup²

Protecting payments means focusing on three key components: compliance, fraud prevention and B2B payment controls. A strong payment setup starts with getting these fundamentals in place.

 

Meet global standards for handling card payments

  • Choose and complete the right Self-Assessment Questionnaire (SAQ) based on how you process payments
  • Encrypt cardholder data and separate payment systems from the rest of your network
  • Run regular vulnerability scans and submit your annual PCI attestation

Block suspicious activity before it causes damage

  • Use tools like AVS, CVV checks and 3D Secure to confirm cardholder identity
  • Set up alerts for unusual activity like rapid transactions or suspiciously large volumes
  • Verify high-risk or unusual payments before approving them

Protect payments made to suppliers and partners

  • Always confirm changes to vendor bank details through a trusted channel
  • Avoid sharing payment info over unsecured emails or messages
  • Reconcile payments regularly to detect errors or suspicious activity
