What type of users does domain separation aim to prevent from accessing data from other companies?

Domain separation is a crucial concept designed to enhance data security and privacy in multi-tenant environments, ensuring that users from one company do not have access to the data belonging to another. In this context, fulfillers are typically users who carry out specific tasks and processes related to service requests. This role may involve interacting with multiple datasets, which can include sensitive information.

The focus of domain separation is to restrict this access and thereby maintain the integrity of each company's data. By preventing fulfillers from seeing or interacting with data outside their designated domain, the system ensures that the operational integrity of each company is upheld. This is vital in scenarios where different clients or departments might have different security needs or compliance requirements.

In contrast, administrators, end users, and managers may have varying access rights and responsibilities, often defined by their roles. While they also require certain levels of access to perform their jobs effectively, the primary purpose of domain separation is about limiting the actions of fulfillers specifically to enhance security and protect sensitive information.
