In SaaS, what does the customer have control over?

In a Software as a Service (SaaS) model, the primary area of control for the customer is the data they input and manage within the service. Customers are responsible for the accuracy, integrity, and privacy of their data, including how it is organized and accessed. While the customer relies on the service provider for the software, operating systems, and underlying infrastructure, they maintain ownership and responsibility for their data.

In contrast, the software, operating system, and platform components are typically managed and maintained by the service provider, giving the customer limited control over those areas. Therefore, the emphasis on customer control in a SaaS environment centers around their data, which is crucial for compliance, security, and operational purposes.
