Key risks include website security, customer account protection, payment fraud, supply chain attacks, third-party integrations, and seasonal capacity/availability requirements.

Is ISO 27001 required for international e-commerce?

While not legally required, ISO 27001 is often expected by enterprise partners, especially in Europe and Asia. It also supports GDPR compliance for handling EU customer data.
