Highly protected financial, proprietary, or customer-related business information (e.g., revenue, trade secrets) processed by an e-commerce platform like Shopify.

This data requires rigorous security and is subject to multiple regulations (GDPR, PCI-DSS, etc.). Its security is an appropriate organisational measure that is paramount for operational continuity.

The breach of this data leads to severe financial and reputational damage far exceeding a standard privacy fine. E-commerce platforms like Shopify have built-in security, but merchants are responsible for the security of their applications and employee access, mandating strong controls and GDPR training.
