Cross-border e-commerce is online retail in which a seller in one country sells goods to buyers in another. Orders may involve international payments, customs declarations, shipping providers, and taxes or duties, so accurate pricing and clear checkout totals matter to both customers and merchants.
These transactions also create cybersecurity risks because platforms handle payment details, account credentials, addresses, and order data across multiple services and jurisdictions. Criminals may target shoppers with fake stores or phishing messages, or attack retailers through account takeover, payment fraud, and stolen customer data. Defenses include strong account authentication, secure payment processing, fraud monitoring, and careful protection of data shared with logistics and customs partners. Reliable checkout systems should also apply fees consistently and show the final cost before payment, reducing confusion that can lead to disputes or fraudulent refund claims.
