Fully Secure

Since PaymentSITE is hosted on Cardknox, sensitive payment data is kept away from your server—keeping you out of scope for PCI compliance. For added protection, PaymentSITE utilizes tokenization to encrypt card data and supports 3DS2 authentication technology to curb fraud and chargebacks.
