What are Data Storage Entities (DSE) according to MasterCard?

Data Storage Entities (DSE) according to MasterCard refer to entities that store MasterCard account data for merchants. This definition highlights the specific role that DSEs play in the payment ecosystem. These entities are crucial because they manage sensitive cardholder and transaction information on behalf of merchants, ensuring that this data is handled according to industry standards and compliance requirements, such as those set forth by the Payment Card Industry Data Security Standard (PCI DSS).

The focus on merchants underscores the responsibility that DSEs have to protect account data during storage, which is vital to prevent data breaches and fraud. This makes them key players in maintaining the security and integrity of payment transactions.

In contrast, other answers do not adequately capture the definition of DSE as specified by MasterCard. References to entities within banks, organizations solely focused on data security, or any entity that merely generates account data do not align with the specific role of DSEs in relation to storing account data for merchants. Understanding this distinction helps clarify the responsibilities and compliance that come with being a Data Storage Entity in the payments landscape.
