Protect data at every boundary
Use tokenised payment data where available, keep secrets out of client code, verify webhook signatures, apply least-privilege access, and retain only the records required for operations and legal obligations. The integration scope determines which PCI responsibilities apply to the merchant.
Risk controls need player context
Payment authentication, device signals, account age, payment-method ownership, transaction velocity, deposit history, chargeback history, and withdrawal behaviour can inform a decision. Controls should increase friction only where evidence supports it and should never replace the operator's KYC, AML, or responsible-gaming programme.
- Authentication and authorisation outcomes
- Velocity and duplicate-payment checks
- Webhook integrity and event replay controls
- Chargeback evidence and transaction audit trail
Operate for change
Security review continues after launch. New markets, methods, products, owners, domains, and payment purposes may require renewed assessment. Incident contacts and escalation paths should be known before they are needed.
