Power BI is a Microsoft product. According to a blog on the platform’s website, Power BI was added to the Microsoft Trust Center in April 2016. The Microsoft Trust center is a single point of reference that documents compliance with various regulations.
HIPAA and the HITECH Act are spotlighted in the Microsoft Trust Center. As a cloud service provider, Microsoft considers itself a business associate for HIPAA-covered entities: “To support our customers’ compliance with HIPAA when utilizing Microsoft enterprise products and services, Microsoft will enter into Business Associate Agreements with its covered entity and business associate customers.”
In the Trust Center, Power BI is listed as an in-scope cloud platform either as a standalone service or included in an Office 365 or Dynamics 365 branded plan or suite.
