The HITRUST CSF is a security and privacy framework that harmonises requirements from many authoritative sources, such as ISO/IEC 27001, NIST SP 800-53, the HIPAA Security Rule and PCI DSS, into one set of controls. The aim is to assess once and report many times: a single HITRUST assessment can give assurance against several standards and regulations at once. It began in healthcare and is now used more widely, particularly by service providers whose customers ask for HITRUST certification in vendor due diligence.
HITRUST offers three main validated assessments. The e1 is an essentials assessment of foundational cybersecurity. The i1 is a broader implemented, one-year assessment built around a threat-informed baseline of good security practice. The r2 is risk-based and tailored to the organisation’s risk profile, technology and scope, gives the most assurance, and is certified for two years with an interim assessment at the one-year mark. In CSF v11.9.0, the e1 baseline has 44 requirement statements and the i1 baseline has 182.
Every validated assessment is tested by a HITRUST Authorised External Assessor firm and then reviewed by HITRUST’s own quality assurance before HITRUST issues the report and, where the result passes, a certification. Assessments are scoped and managed in MyCSF, HITRUST’s platform, which also supports inheritance of controls already assessed at cloud and service providers.
HITRUST updates the CSF regularly, reconciling it against threat intelligence and adding or refreshing authoritative source mappings. Version 11.9.0 refreshed the NIST SP 800-53 mapping, modified the HIPAA mappings and added an Agentic AI factor for the AI Security Certification. HITRUST publishes transition deadlines by advisory when assessments must move to a newer version. The full framework is available from HITRUST under its licence terms.
