Framework: HITRUST

The HITRUST assurance programs—e1, i1, and r2—represent a graduated path of control maturity and assurance depth. The e1 assessment provides entry-level, baseline assurance designed for organizations seeking rapid validation of essential cybersecurity practices. The i1 assessment builds on that by requiring implemented and operating controls validated through evidence testing. Finally, the r2 assessment offers the highest assurance level, emphasizing comprehensive testing, evidence sufficiency, and quality assurance oversight. For certification candidates, understanding these distinctions is crucial for selecting the right assurance program based on organizational goals and risk appetite.

Each assurance tier serves a specific business purpose. Smaller organizations or startups might begin with e1 to quickly demonstrate baseline hygiene, while mature enterprises and regulated entities typically pursue r2 for its depth and credibility. The i1 acts as a bridge—balancing speed and rigor. In practice, exam candidates must connect these levels with concepts like PRISMA scoring, shared responsibility, and control inheritance to demonstrate mastery of HITRUST’s scalable approach to assurance.
