HITRUST CSF Assessments for e1, i1, and r2: A Comparative Breakdown

Explore the differences between HITRUST CSF e1, i1, and r2 assessments, their requirements, assurance levels, and which option fits your organization’s security needs.
For many organizations, the decision to pursue HITRUST seems straightforward until they discover there are three different assessment options.
A healthcare SaaS provider receives a security questionnaire from a prospective customer and is told that HITRUST certification would improve the vendor review process. A growing cloud services company wants to demonstrate stronger security assurance to enterprise buyers. A healthcare organization is preparing for stricter third-party risk requirements. All three organizations may arrive at the same question: Which HITRUST assessment should we choose?
Organizations can pursue an e1, i1, or r2 assessment, each designed to deliver a different level of assurance. While they all fall under the HITRUST ecosystem, the scope, rigor, validation requirements, and business value of each assessment can vary significantly.
In this article, we compare e1, i1, and r2 assessments and explain how to choose the right HITRUST certification path.
Why HITRUST Certification Matters
As organizations rely on cloud services, third-party vendors, and interconnected systems, customers and business partners expect greater transparency into how sensitive information is protected. HITRUST provides a recognized way to demonstrate that security controls are in place and aligned with industry best practices.
-
Building Trust Through Independent Validation
Customers often look for independent proof that an organization’s security practices are effective. A validated HITRUST CSF certification provides that assurance by demonstrating that security controls have been reviewed against established requirements. This can help build confidence during vendor assessments, customer due diligence reviews, and procurement processes.
-
Supporting Business Growth
Security reviews have become a common part of the buying process, particularly in healthcare and other regulated industries. Organizations with HITRUST compliance are often better positioned to respond to customer security requirements, helping reduce delays and build trust with prospective clients.
-
Aligning Security and Compliance Efforts
The HITRUST CSF framework brings together requirements from multiple standards and regulations into a single framework. This helps organizations streamline their compliance efforts, reduce duplication, and take a more consistent approach to security and risk management.
HITRUST Assessments Explained: e1, i1, and r2 Levels
One of the first questions organizations encounter when exploring HITRUST certification is: Which assessment level is right for us? The answer depends on several factors, including the sensitivity of the data you handle, customer expectations, regulatory obligations, and the maturity of your security program.
HITRUST introduces three assessment options: e1, i1, and r2. These assessments provide different levels of assurance, allowing organizations to choose a path that aligns with their risk profile and business objectives.
What is HITRUST e1 Assessment?
The e1 assessment is the most streamlined option within the HITRUST assurance program. It was developed for organizations that need to demonstrate foundational cybersecurity practices but may not yet require the higher levels of assurance provided by i1 or r2.
The assessment focuses on 44 essential security requirements covering areas such as access controls, password management, security awareness training, vulnerability management, endpoint protection, and data security. The objective is to validate that basic cybersecurity controls are in place and functioning as expected.
For many organizations, e1 serves as a starting point in their HITRUST journey. It allows them to establish a recognized level of assurance while building the processes and controls needed for more advanced assessments in the future.
The E1 assessment demonstrates security commitment without the complexity of larger assessments, helping organizations build trust, improve governance, and prepare for future compliance.
Best suited for:
-
Startups and early-stage organizations
-
Emerging healthcare technology providers
-
Organizations beginning to formalize their security programs
-
Vendors responding to basic customer security requirements
What is HITRUST i1 Assessment?
The i1 assessment was introduced to address modern cybersecurity threats and provide stronger assurance around the implementation of security controls. While e1 focuses on foundational practices, i1 evaluates whether organizations have established and operationalized a broader range of cybersecurity controls.
The assessment includes approximately 182 requirements and focuses on areas such as risk management, incident response, security monitoring, third-party risk management, identity and access management, and data protection. These requirements reflect many of the security capabilities organizations are expected to maintain in today's threat landscape.
Unlike e1, which primarily validates security fundamentals, i1 provides greater confidence that security controls are actively managed and operating within the organization.
Many organizations choose i1 because it balances assurance and complexity, providing stronger security assurance than e1 without the demands of a full risk-based assessment.
Best suited for:
-
Growing SaaS and technology providers
-
Healthcare vendors supporting regulated organizations
-
Cloud service providers
-
Organizations undergoing detailed customer security reviews
What is HITRUST r2 Assessment?
The r2 assessment is the most comprehensive and rigorous assessment available within the HITRUST framework. It is designed for organizations that require the highest level of assurance and need to demonstrate that their security controls are aligned with their unique risk environment.
Unlike e1 and i1, which use predefined sets of requirements, the r2 assessment applies a risk-based approach. Factors such as organization size, geographic presence, regulatory obligations, industry sector, technology complexity, and data sensitivity influence the scope of the assessment. As a result, the number of applicable HITRUST CSF controls can vary significantly between organizations.
Beyond evaluating whether controls exist and operate effectively, r2 also examines the maturity of security practices. This includes areas such as governance, oversight, measurement, management review, and continuous improvement activities.
The r2 assessment is HITRUST’s highest level of assurance, offering a risk-based evaluation of security effectiveness and program maturity. It is often pursued to meet customer requirements or regulatory demands.
Best suited for:
-
Healthcare providers and health systems
-
Health plans and healthcare clearinghouses
-
Organizations managing large volumes of sensitive data
-
Companies facing strict customer, regulatory, or contractual requirements
HITRUST CSF Assessment Process Explained
While the specific requirements may vary depending on whether an organization pursues an e1, i1, or r2 assessment, the overall HITRUST audit process follows a structured approach designed to evaluate how effectively security controls are implemented and managed. Understanding the process can help organizations plan resources, set realistic timelines, and avoid common challenges during the assessment journey.
Step 1: Define the Assessment Scope
The process begins by determining what will be included in the assessment. Organizations identify the systems, applications, business processes, and environments that store, process, or transmit sensitive information. A clearly defined scope helps ensure that the assessment focuses on the areas that are most relevant to the organization's risk profile and compliance objectives.
Step 2: Prepare for the Assessment
Before the formal assessment begins, organizations typically conduct readiness activities to evaluate their current security posture against applicable HITRUST CSF requirements. This stage often involves reviewing policies and procedures, assessing existing controls, identifying gaps, and collecting supporting evidence. Thorough preparation can help reduce delays later in the assessment and provide greater confidence that controls are operating as intended.
Step 3: Complete the Validated Assessment
Once preparation activities are complete, the organization works with a HITRUST Authorized External Assessor to perform the assessment. During this phase, assessors review documentation, examine evidence, interview key stakeholders, and evaluate the effectiveness of applicable HITRUST CSF controls. The objective is to determine whether the organization's controls meet the requirements associated with the selected assessment level.
Step 4: HITRUST Quality Assurance Review
Following the validated assessment, the results are submitted to HITRUST for an independent quality assurance review. HITRUST examines the assessment findings, evidence, and scoring methodology to verify consistency and accuracy. This additional review helps maintain the integrity of the certification process and ensures assessments are evaluated against established standards.
Step 5: Certification Decision
After the quality assurance review is complete, HITRUST issues the final assessment results. Organizations that successfully meet the applicable requirements receive certification or validated assessment status based on the assessment type. Achieving certification demonstrates that the organization has met a recognized level of security assurance and can provide independent validation of its security practices to customers, partners, and stakeholders.
The Right HITRUST Assessment Is About More Than Certification
Not all security certifications communicate the same message to customers, partners, and stakeholders. In the HITRUST ecosystem, each assessment level represents a different level of assurance, validation, and organizational maturity. Understanding these distinctions is critical because the value of certification often depends on how well it aligns with the expectations of the organizations evaluating your security posture.
Each assessment serves a distinct purpose. e1 establishes a foundation for organizations beginning their security assurance journey, i1 demonstrates that cybersecurity practices are actively operating across the business, and r2 provides a deeper, risk-based evaluation for organizations facing higher levels of regulatory scrutiny and stakeholder expectations. Understanding these differences is essential to making an informed certification decision.
