HITRUST (Health Information Trust Alliance) maintains the HITRUST CSF (Common Security Framework), a consolidated security and compliance framework that maps to HIPAA, NIST 800-53, ISO 27001, PCI DSS, and several other standards. HITRUST CSF certification is increasingly expected by healthcare organizations from their technology partners.
For patient portal vendors, HITRUST certification signals comprehensive security across multiple frameworks. It’s not legally required (HIPAA itself is the legal requirement), but it streamlines vendor evaluation and is often demanded by larger health systems.
