Is the HITRUST CSF a replacement standard for HIPAA or NIST 800-53?

The HITRUST CSF is not intended to replace existing regulatory frameworks such as HIPAA or security standards like NIST 800-53. Instead, the CSF harmonizes and integrates requirements from these and other authoritative sources into a single certifiable framework. For example, HIPAA Security Rule provisions and NIST 800-53 controls are mapped into the CSF domains and requirement statements. This enables organizations to demonstrate compliance with multiple frameworks through one assessment. However, the CSF does not eliminate or supersede the original obligations. Covered entities must still comply with HIPAA, and federal contractors may still need to align with NIST standards directly. The CSF serves as a consolidated implementation tool, not a legal or regulatory replacement.
