- Secure Acceptance Web / Mobile requires a customer to be redirected to the CyberSource payment page.
- Secure Acceptance Silent Order POST does not require a customer to be redirected to the CyberSource payment page, and also does not require a shop to be PCI DSS compliant, because the sensitive payment data are passed directly (and asynchronously, without a page reload / refresh in browser) to the CyberSource server. It is a modern solution, and it works similar to my Stripe, 2Checkout, Checkout.com payment extensions.
