How many domains are there in an assessment?

The HITRUST CSF is structured into19 domainsthat provide comprehensive coverage of information security and privacy practices. These domains represent major categories of controls such as Information Security Management, Endpoint Protection, Network Security, Access Control, Configuration Management, Incident Management, and Data Protection. Each domain contains multiplecontrol referencesmapped to requirement statements, which are tailored to organizational and regulatory factors. This domain structure ensures that assessments address administrative, technical, and organizational safeguards consistently across industries. All assessment types—whether e1, i1, or r2—utilize these 19 domains, although the number of requirement statements varies depending on the scope. The domain-based structure also supports HITRUST’s mapping to authoritative sources like NIST, HIPAA, and ISO, ensuring consistency across compliance obligations.
