HITRUST vs SOC 2: which one does your customer actually require?
HITRUST is a certification built on a fixed, HITRUST-owned control set, while SOC 2 is an AICPA attestation report on a service organization's controls against the Trust Services Criteria. A HITRUST result is produced when an Authorized HITRUST External Assessor tests your controls and HITRUST performs central quality assurance before issuing the report. A SOC 2 report is issued by an independent CPA firm after it examines your system description and controls. The first thing to establish is therefore not which framework is stronger, but which one the requester actually named in the contract, questionnaire or regulatory request. If the document says HITRUST, a SOC 2 report will not satisfy it, and the reverse is also true. Ask the customer for the exact wording, the assessment level they expect and whether they accept an alternative in writing.
The right answer then depends on three things: the sectors you serve, the obligations you must cover beyond the one requester, and how much reuse you need. Healthcare buyers and their third-party risk programs commonly ask for HITRUST, while many other customers accept SOC 2. HITRUST's CSF harmonizes more than 60 authoritative sources, so a single assessment can be mapped to several obligations, which matters if you face HIPAA, ISO/IEC 27001 and PCI requirements at once. Confirm with each requester which mappings they will accept. Validity also differs: e1 and i1 certifications last one year and r2 certifications last two years with an interim assessment, so plan the renewal cycle alongside your customer contracts.
Your organization owns its controls and makes the scope decisions. An implementation partner such as DeployOpen can prepare systems, configurations and evidence for either path, but only an independent External Assessor, a CPA firm or a certification body issues the HITRUST result or SOC 2 report. Before committing budget, ask any provider to show which deliverables are yours, which belong to the assessor and which are readiness work. Compare the two options on the same evidence set so the work you do for one can carry over to the other.
How HITRUST and SOC 2 differ on the points buyers check
This table compares the two assurance results on the questions procurement and security teams ask first: who issues the result, how the control set is defined, how quality is checked, how long the result lasts and how it is scored. Read each row as a question to put to a vendor's report, since the answers determine how much weight the result carries for your third-party review.
| Point buyers check | HITRUST certification | SOC 2 report |
|---|---|---|
| Source of the framework | HITRUST CSF, a proprietary framework based on ISO/IEC 27001 and 27002 that harmonizes more than 60 authoritative sources | AICPA Trust Services Criteria (2017), developed by the AICPA for service organizations |
| Type of result | Certification of a validated assessment, scored and issued by HITRUST | Attestation report issued by an independent CPA firm under AICPA standards |
| Control set | Defined requirement statements for each assessment level (e1, i1 or r2), so results are comparable across vendors | Flexible criteria: the service organization selects controls and describes them in its system description |
| Assessor role | Only Authorized HITRUST External Assessor organizations may perform the validated assessment | Licensed CPA firm performs the examination; no HITRUST-style assessor authorization applies |
| Central quality check | HITRUST performs central quality assurance before it issues the report | No central quality review by the framework owner; the CPA firm's own process applies |
| Scoring model | Maturity scoring per assessment domain, with minimum domain averages of 83 for e1 and i1 and 62 for r2 | Pass or exception-based opinion against the criteria in scope; no maturity score |
| Validity period | One year for e1 and i1; two years for r2 with an interim assessment in the 90 days before the first anniversary | Point-in-time or period-of-time report; the report date and test period define its currency, not a fixed renewal |
| Cross-regulation mapping | One assessment can be mapped to several obligations such as HIPAA, NIST SP 800-53 and PCI | Mapping to other frameworks is limited and generally prepared by the service organization or its assessor |
Why certification and attestation are not interchangeable
A HITRUST result and a SOC 2 report answer different questions, so a relying party should read them differently. A HITRUST certification is issued by HITRUST itself. It follows a validated assessment that an Authorized HITRUST External Assessor performed against a defined control set, and HITRUST performs central quality assurance before it issues the report and letter. The certificate therefore tells the reader that a third party tested the scoped controls against HITRUST's requirements and that HITRUST checked that testing before releasing the result. A SOC 2 report is different in kind. It is an attestation by a CPA firm about the design and operating effectiveness of a service organization's controls over a stated period, measured against the AICPA's Trust Services Criteria that the organization and its auditor select.
HITRUST's own comparison describes SOC 2 as an attestation with flexible criteria, and the practical effect is that two SOC 2 reports can cover different selected criteria, systems and time windows while both being valid. A HITRUST i1 or e1 result, by contrast, is tested against a fixed requirement set, so a reader can compare two certified vendors on the same baseline. Neither model is stronger in general. The question for a reader is which proof matches the risk. If a customer needs a common yardstick across many vendors, a fixed certification is the closer fit. If the customer needs evidence about specific services, periods or trust criteria that the vendor chose, a SOC 2 report read in full may answer more precisely.
Before relying on either document, confirm the scope statement, the systems covered, the period or validity date, and any carve-outs or inherited controls named in it. Check the issuing party as well: a HITRUST certification should be verifiable through HITRUST, and a SOC 2 report should be signed by the CPA firm that performed it. Ask the vendor which document it expects you to accept and whether any control your contract depends on falls outside that document's scope. Treating the two as interchangeable is the most common reading error, because each one proves something the other does not.
Can one assessment cover both, and what carries over?
A healthcare vendor whose customers ask for HITRUST usually needs a certification that health system buyers will accept, and the question is whether its existing security program can be shown against that standard without starting from zero. HITRUST describes its CSF as harmonizing more than 60 authoritative sources, including NIST SP 800-53, ISO 27001, HIPAA, FedRAMP and PCI, so one assessment can be mapped to several obligations rather than repeated for each. Work already done for HIPAA or other customer questionnaires may therefore give evidence that maps into the CSF.
- Source mapping: Controls mapped to HIPAA or ISO 27001 may support HITRUST requirement statements, but each mapping must be checked against the actual evidence.
- Insights Reports: HITRUST Insights Reports can map e1, i1 or r2 results to HIPAA, which may help answer customer questions about HIPAA coverage.
- Evidence reuse: Policies, access reviews and vulnerability records produced for other customers can often be reused if they cover the scope and period the assessor tests.
- Scope gaps: Systems that handle protected health information but sit outside the chosen scope will not be covered by the result.
Reuse depends on the assessor's testing and the defined scope. Confirm with the External Assessor which existing evidence it will accept and how the HIPAA mapping is applied to your scope.
A SaaS company that already holds a SOC 2 report and now needs HITRUST faces a different question: how much of its SOC 2 work can count toward a HITRUST assessment. HITRUST publishes resources on applying SOC 2 work toward an e1 assessment, including an eBook on moving from SOC 2 to HITRUST e1. Those materials show the intended path, but the amount of carry-over is set by how the External Assessor tests each requirement, not by the existence of a SOC 2 report.
- Control overlap: Access management, change control, logging and vulnerability management often appear in both programs, which makes them the first candidates for reuse.
- Period and scope: A SOC 2 examination covers a stated period and system boundary. The HITRUST scope and evaluation window may differ, so the assessor must confirm the evidence applies.
- Gap areas: HITRUST requirement statements can ask for controls that a SOC 2 report did not test, such as specific maturity expectations, so new work may be needed.
- Path to e1: A company may start with the e1 and carry its work forward to the i1 and r2, which is a planning choice to discuss with the assessor.
Confirm with the assessor, before scoping, which SOC 2 evidence and test results it will consider, and whether any of it counts toward the scoring rather than only supporting the fieldwork.
A company facing HITRUST and SOC 2 requests at the same time has to decide whether one body of work can answer both, or whether two programs must run in parallel. The answer depends on the timing of each request, the scope each customer expects and the assessor's view of reuse. HITRUST presents its CSF as a single control set that can be mapped to several obligations, which is the basis for a combined approach, but the two outputs remain different products with different testing rules.
- Shared control set: One control inventory can track evidence for both programs, with a clear owner and test date for each control.
- Different outputs: A SOC 2 report is an attestation issued by a CPA firm, while HITRUST certification is issued by HITRUST after validated assessment, so the reports cannot substitute for each other.
- Timing conflicts: Fieldwork windows, observation periods and HITRUST validity periods may not line up, which affects when each request can be answered.
- Governance: One evidence register and one owner for remediation reduce duplicated work across the two audits.
Before committing to a combined plan, ask both the HITRUST External Assessor and the CPA firm in writing how they will rely on each other's testing and scope.
Which factors should decide the choice
Four of the decisions below usually settle the question before any vendor is contacted. Work through them with the requester first, because the answer to each one points toward either a HITRUST certification or a SOC 2 report, or toward both.
The customer's named requirement
Start by asking the requester which document, questionnaire or contract clause names the assurance they need. Some customers specify a HITRUST certification at a particular level, while others accept any independent report. Get the exact wording, the level if one is named, and whether the customer will accept a validated assessment, a SOC 2 report or a mapped questionnaire. A vague request for "HITRUST or equivalent" should be resolved in writing before any scoping starts.
Validity and renewal cadence
A HITRUST e1 or i1 certification is valid for one year, and an r2 certification is valid for two years with an interim assessment due in the 90 days before the first anniversary. A SOC 2 report covers a stated period of time and is refreshed on the customer's cycle. Ask the requester how often they expect fresh assurance, whether they track expiry dates in their third-party risk program, and who will carry the renewal work.
A fixed control set for comparison
HITRUST assesses against a defined CSF baseline for each level, so two vendors certified at the same level have been tested against the same requirement statements. A SOC 2 report is built on criteria the auditor and the service organization agree on for each engagement, which gives more flexibility but makes side-by-side comparison harder. Ask whether the customer's review team needs to compare vendors directly, as healthcare third-party programs often do.
Existing SOC 2 work to reuse
If the organization already completes SOC 2 examinations, much of the control evidence, system descriptions and population lists may carry forward. HITRUST publishes guidance on applying SOC 2 work toward an e1 assessment. Ask the team which controls were tested in the last SOC 2 period, which were exceptions, and whether the same evidence can satisfy HITRUST requirements without rebuilding it. Gaps should be mapped before anyone commits to a level.
Internal capacity to run either
Both paths require control owners who can produce evidence on demand, a single person to coordinate assessor requests, and time to remediate findings before fieldwork. A HITRUST validated assessment also requires an Authorized External Assessor, and a SOC 2 examination requires a CPA firm. Ask who will own the evidence, how many hours per month the team can spare, and whether the organization has run an independent examination before. Capacity gaps usually decide the timeline more than the framework does.
How a HITRUST path and a SOC 2 path run side by side
The sequence shows a buyer where the two paths share effort, where they diverge, and which output each phase leaves behind so the choice of path can be planned before any money is committed.
Decide the scope and the report the buyer needs
The organization, with its customers or contract owners, settles which systems, locations and services sit in scope and which assurance output the buyer actually asks for. For HITRUST, that means choosing between the e1, i1 and r2 certifications. For SOC 2, it means choosing the Trust Services Criteria and the report type. Confirm the requirement in writing with the customer before any work starts. The output is a written scope statement and a named deliverable that both sides accept.
Run readiness work against the chosen control set
The organization, often with an implementation partner, maps its existing controls to the requirements of the chosen path. For HITRUST, the control set is fixed by the assessment level, so gaps are measured against defined requirement statements. For SOC 2, the control set is written by the organization and must fit the criteria in scope, so the team defines the controls it will describe and test. The output is a gap list with owners and an agreed remediation plan. Readiness is complete when the owners have signed off on what remains open.
Collect and retain evidence for each control
The organization produces the records that show each control operated, such as access reviews, change tickets, backup restore logs, training completions and vendor reviews. Both paths require evidence that is dated, attributable and retained in a form an assessor can sample. HITRUST evidence is organized against the requirement statements and scored by domain. SOC 2 evidence is organized against the controls the organization describes. Open-source platforms can generate much of this evidence if logging and retention are configured from the start. The output is an evidence repository that an independent reviewer can walk through without help from the people who created it.
Complete fieldwork with the external assessor or CPA firm
For HITRUST, an Authorized HITRUST External Assessor organization tests the evidence and scores each domain as part of the validated assessment. The fieldwork window for a validated assessment is at most 90 days. For SOC 2, a licensed CPA firm tests the controls over the observation period defined in the engagement and forms its opinion. In both cases, the assessor, not the organization or its implementation partner, decides what passes. The output is an assessor's working record of testing and any exceptions raised during fieldwork.
Pass HITRUST quality assurance before issuance
HITRUST performs central quality assurance on the submitted validated assessment before any report or certification is issued. This review is a step with no SOC 2 equivalent. The HITRUST team can return questions to the external assessor, and the organization should expect that round trip in its planning. SOC 2 reports have no central body reviewing them in this way, so the quality of the CPA firm's work sits with that firm and its licensing body. The output on the HITRUST path is a quality-reviewed result that HITRUST releases for issuance.
Receive the report or certification and share it
The HITRUST path ends with a HITRUST certification letter and a validated report, issued by HITRUST and describing the scope and result. The SOC 2 path ends with an independent auditor's report that describes the controls and the test results. The organization then shares the document with customers under the terms of its agreements. Recipients should read the scope, the period covered and any exceptions, not only the headline result. The output is a document a customer can review against its own third-party risk requirements.
Maintain the result through renewal
A HITRUST e1 or i1 certification is valid for one year, and an r2 certification is valid for two years with an interim assessment due in the 90 days before the first anniversary. Plan the next assessment before the current result expires, because a lapse affects customers and insurers. A SOC 2 report covers a period that has passed, so the organization needs a new examination for each reporting period the customer requests. The output is an updated evidence set, a dated renewal plan and, for HITRUST, a confirmed interim or renewal assessment.
What must be in place before either assessment starts
A HITRUST validated assessment and a SOC 2 examination both test what an organization can show, not what it intends to do. The five items below are the groundwork either engagement depends on, and a readiness review should confirm each one before fieldwork or an examination period begins.
A defined system scope
Name the systems, services, data stores, locations and third parties that fall inside the assessment boundary, and write down what sits outside it. HITRUST scopes its assessment in MyCSF, while a SOC 2 examination describes the system in its report, so the same boundary drives both. To check it, compare the scope statement against an up-to-date asset inventory and ask whether every system that processes the in-scope data appears in one of the two lists.
Controls mapped to the chosen framework
Map each internal control to the requirement it satisfies in the framework you will be tested against. For HITRUST, that means the CSF requirement statements in the e1, i1 or r2 set. For SOC 2, it means the Trust Services Criteria you selected. To check the mapping, pick a sample of controls and confirm that each one has an owner, a description of how it operates and a test that shows it works.
Dated and retrievable evidence
Assessors and auditors test whether a control operated during a defined period, so evidence must carry dates and be findable without a rebuild. Store access reviews, change tickets, vulnerability scans and training records in a system that keeps timestamps and approval trails. In a readiness review, ask for a random control and time how long it takes to produce its evidence for a specific date.
A named internal owner
Assign one accountable person who makes decisions about scope, control gaps and evidence disputes, and who answers to the assessor or auditor. Both engagements have a single point of contact on the organization's side, and delays often come from unclear ownership rather than missing controls. To check this, confirm the owner can name the control owners for each domain or criteria group and has authority to change a control without another approval chain.
Reusable reports from earlier work
Before starting, inventory any SOC 2 reports, prior HITRUST results, cloud provider reports and vendor assessments that cover the same systems. Decide which controls those reports can support and which must be tested again, and document the basis for each reliance decision. In a readiness review, check the period each report covers, the carve-outs it lists and whether the complementary user entity controls assigned to your organization are actually operating.
Who owns controls, who prepares evidence and who issues the result
Your organization owns the controls, the scope and the risk decisions, whichever framework applies. Operating a control is your job every day, and no outside party can accept that accountability for you. Assessors will ask your staff to explain how each control works, who runs it and how it is monitored, so people who understand the environment need to be involved from the start.
- Control ownership: Named owners run each control, keep it operating and answer assessor questions about it.
- Scope decisions: Your team decides which systems, products, locations and third parties fall inside the assessment boundary.
- Evidence approval: Someone accountable reviews evidence before it goes to the assessor and confirms it reflects how the control actually runs.
- Risk and exception calls: Your leaders accept residual risk, approve exceptions and sign off on remediation plans.
- Ongoing operation: Controls must keep working between assessments, because a point-in-time review will not hold up if practice drifts.
Before engaging anyone, confirm internally who will sign the management assertions or representations that the framework requires.
An implementation partner such as DeployOpen works inside your environment to prepare the systems, control evidence and readiness materials that an assessment will examine. This work is preparation, not testing. The partner can configure logging, access controls, backup routines and documentation so they produce evidence, but it cannot decide whether the controls pass, and it cannot issue a report or certificate.
- System preparation: Configure self-hosted open-source platforms in your cloud accounts, data centers or air-gapped networks to meet the control requirements.
- Evidence production: Set up collection of logs, configuration baselines, change records and access reviews that a control owner can approve.
- Readiness materials: Prepare gap analyses, control narratives and walkthrough guides that your team reviews before any assessor sees them.
- Documentation handover: Deliver runbooks and records so your staff can operate the controls after the engagement ends.
- Limits of the role: The partner does not attest, score, test independently or sign any assessment output.
Ask for a written scope that lists each deliverable and states that the partner does not issue reports or certificates.
The independent party tests the controls and issues the result. For a HITRUST validated assessment, only an Authorized HITRUST External Assessor organization may perform the work submitted for certification, and HITRUST performs central quality assurance before it issues the report. For SOC 2, a licensed CPA firm performs the examination and issues the report. The assessor's independence is what gives the result its value to the customers who read it.
- Independence boundary: The assessor cannot design, implement or remediate the controls it later tests for the same engagement.
- Testing: The assessor samples evidence, walks through processes and forms its own conclusions.
- Reporting: The assessor issues the report or assessment output, and HITRUST issues the certification after its quality review.
- Fieldwork limits: HITRUST validated fieldwork runs within a window of at most 90 days for e1, i1 and r2.
- Verification: Check a HITRUST firm in the external assessor directory and confirm a CPA firm's license before you sign.
Confirm the assessor's independence in writing before you share your evidence plan with the implementation partner.
How to check an assessor, CPA firm or consultant
A HITRUST validated assessment and a SOC 2 examination each depend on a firm that holds the right credentials and stays independent of the work it reviews. The cards below set out the checks to run on an assessor, a CPA firm and any consultant before you commit budget or share evidence.
Confirm an Authorized External Assessor
Only Authorized HITRUST External Assessor organizations may perform the validated assessments submitted for an e1, i1 or r2 certification. Look up the firm in HITRUST's Find an External Assessor directory and confirm it is listed as authorized, not merely as a consultant or readiness provider. The directory also shows whether the firm is an AICPA member, which matters if you hold a SOC 2 report alongside your HITRUST work.
Confirm CPA firm standing for SOC 2
A SOC 2 report is issued by a licensed CPA firm under AICPA standards, so the report is only as credible as the signing firm's standing. Ask for the engagement partner's license state, confirm the firm's AICPA membership and check that the firm's reports are accepted by your customers' third-party risk teams. Verify these details with the firm and the relevant state board rather than relying on marketing material.
Separate the auditor from the preparer
The firm that examines your controls must not design, operate or prepare the evidence it tests. A consultant who builds your policies, configures tooling and then collects screenshots for the assessor creates a conflict that an assessor or CPA firm will need to manage. Ask every vendor in the engagement to name its role in writing, and confirm that the independent firm does not perform remediation for the same findings it reports.
Ask about sector experience without client names
Experience with health systems, payers or business associates matters because it shapes how an assessor interprets evidence for your environment. Ask how many engagements the team has completed in your sector and at what assessment levels, and how it handles scoping questions specific to your data flows. Reputable firms will describe patterns and methods without naming their clients, and they should not offer to share another organization's report.
Require a written scope and deliverables
Before signing, ask for a written scope that lists the framework or assessment type, the systems and locations in scope, the carve-outs or inherited controls, the evidence the firm will request and the deliverables it will issue. For a SOC 2 examination, confirm the report type and period. For HITRUST, confirm the assessment level and the external assessor's fieldwork timing. Vague scopes are the most common source of later change orders.
Questions buyers ask before choosing HITRUST or SOC 2
Does a SOC 2 report satisfy a HITRUST request?
It depends on who is asking and what they want reused, so confirm with the requester before assuming it does. A SOC 2 report is an attestation on flexible criteria, while a HITRUST certification is a validated assessment against a fixed control set that an Authorized HITRUST External Assessor performs and HITRUST quality-checks before issuing. Some customers accept SOC 2 work as a starting point for an e1 assessment, and HITRUST publishes material on moving from SOC 2 to e1. Ask the requester which assessment level they need, whether they accept a SOC 2 report as evidence, and how they will read the result before you commit scope.
How long does each take, and how much work does the internal team carry?
Timelines depend on scope, system readiness and how quickly evidence can be gathered, so there is no single duration that applies to every organization. A HITRUST validated assessment has an assessor fieldwork window of at most 90 days, but controls usually need to operate for a period before testing, and QA and draft report review follow fieldwork. A SOC 2 examination covers a review period set by the auditor and the service organization. In both cases the internal team owns system owners, policy approvals, evidence collection and answers to auditor questions. Ask any provider for a written timeline that separates readiness, fieldwork and reporting.
Can our team run a HITRUST or SOC 2 effort without outside help?
Many teams run the internal side themselves, but the independent work cannot be done in-house. Only an Authorized HITRUST External Assessor can perform a validated assessment submitted for certification, and only an independent CPA firm can issue a SOC 2 report. Your team can own controls, policies and evidence. An implementation partner such as DeployOpen can prepare self-hosted platforms, configuration, logging and evidence for the assessor or auditor, but it does not issue reports or certificates. Decide early which tasks you will keep and which you will outsource, and write that split into the scope.
What drives the cost of HITRUST compared with SOC 2?
Cost is driven by the number of systems in scope, the number of third parties whose results you must inherit or carve out, the maturity of your evidence, and the assessment level or report type you choose. For HITRUST, the assessor and HITRUST platform fees are paid to separate parties, and readiness work is an additional cost you may or may not need. For SOC 2, the CPA firm's fee rises with the trust services criteria in scope and the length of the review period. Ask each provider for an itemized quote that names who is paid for each item, what is one-time and what recurs, and what changes if scope grows.
What does HITRUST validity mean for renewal?
HITRUST certifications have fixed validity: one year for e1 and i1 and two years for r2, and the r2 requires an interim assessment due in the 90 days before the first anniversary. A lapsed certification has to be pursued again, so the renewal plan should start well before the expiry date. Your customers may ask for a current certification at each contract renewal, so budget for the recurring assessment cycle, not only the first certification. Confirm the renewal path and interim requirements with your assessor before you sign.
Can we run HITRUST and SOC 2 at the same time?
Yes, many organizations hold both, and the work can overlap because HITRUST harmonizes many authoritative sources, including those that SOC 2 controls touch. Overlap is not automatic, though. The two engagements use different criteria, different assessors and different review periods, so evidence collected for one may need to be re-scoped or re-sampled for the other. Map your controls once, agree with each assessor which evidence they will accept, and keep a single evidence repository so the same records serve both examinations.
Which should an engineer expect to test more closely?
Engineers should expect HITRUST validated assessments to test specific requirement statements scored across 19 assessment domains, with domain averages that must reach 83 for e1 and i1 and 62 for r2. SOC 2 testing follows the trust services criteria and the control descriptions written for your system, with the auditor sampling operating evidence over the review period. In both cases, check that logging, access reviews, change records and backups produce evidence on a schedule, because gaps are usually found in the evidence rather than the design. Confirm the exact evidence formats with your assessor or auditor before you configure tooling.
How DeployOpen prepares systems and evidence for either path
DeployOpen works on the HITRUST or SOC 2 side of the decision by preparing the systems and evidence that an independent assessor will test. We do not issue reports or certificates. Authorized External Assessors and CPA firms do that, and the organization owns its controls throughout.
How we scope
- Engagements are fixed-scope, with systems, controls, deliverables and timelines agreed in writing before work starts.
- We identify which in-scope systems and data flows the assessor will sample, so evidence covers the right boundary.
- The written scope states which parts remain the organization's own work and which parts DeployOpen will prepare.
How we build
- We deploy and harden self-hosted open-source platforms inside your own cloud accounts, data centers or air-gapped networks.
- We configure logging, access control, change records and backups so they generate evidence an assessor can sample.
- We run security testing against in-scope applications and infrastructure to surface gaps before fieldwork begins.
How we hand over
- We document controls, procedures and evidence locations in a form your team and assessor can follow.
- We deliver an evidence map that links each control or requirement to the artifact that supports it.
- Your team keeps administrative ownership of the platforms, with documentation sufficient to operate them after handover.
How we support
- Ongoing support, upgrades and continuous testing are available as retainers after the initial engagement ends.
- Retainers can keep evidence current between assessment cycles, including the periodic work HITRUST r2 or SOC 2 periods require.
- Confirm with your assessor which evidence formats and sampling periods they accept before we finalize the scope.
