HITRUST vs SOC 2 vs HIPAA: A Healthcare Vendor Certification Guide

If you’re evaluating a print and mail vendor to handle protected health information, you’ve probably run into three terms that get tossed around like they mean the same thing: HIPAA, SOC 2, and HITRUST. They don’t. One is a federal law, one is an attestation report, and one is a certifiable framework. Mixing them up leads to bad vendor decisions, because a “HIPAA-compliant” claim and a HITRUST certification carry very different weight when a health plan audits the partners printing and mailing its member communications.

This guide breaks down what each one covers, when a SOC 2 report is enough, and when a payer will require HITRUST certification before your vendor can touch a single record. We keep the comparison vendor-neutral. For the mechanics of moving PHI through a mail stream, see our companion guide on handling PHI in the mail stream. For how to read an attestation report line by line, see our guide on reading a SOC 2 Type II report.

The fastest way to clear things up is to see all three side by side. HIPAA is the law you must follow. SOC 2 is an auditor’s opinion on your controls. HITRUST is a certification you earn against a prescriptive control set.

Here’s a quick way to think about it. HIPAA sets the legal floor everyone in the mail production chain must meet, from the health plan down to the vendor running the inserter. SOC 2 gives your customer an auditor’s view of how you run controls. HITRUST gives a payer a certification they can trust without having to reinterpret your evidence themselves.

HITRUST certification means an organization has met a prescriptive set of security and privacy controls, scored for maturity and validated by an authorized external assessor. You can’t self-certify. According to the HITRUST Alliance, every assessment is built on the HITRUST CSF, a framework that folds HIPAA, the NIST Cybersecurity Framework, and ISO 27001 into a single control set.

That last point matters most for mail vendors. A print and mail operation that processes healthcare statements touches PHI at every stage: data ingestion, variable print, inserting, and postal handoff. Instead of proving HIPAA compliance separately from ISO or NIST, a HITRUST-certified mail vendor demonstrates all of them through one certification. The framework maps the overlapping requirements so a payer sees one result, not three partial ones.

HITRUST offers three assessment levels, and the difference comes down to how many controls your organization needs to meet. Per the HITRUST Alliance, here’s how they break down:

All three lead to a HITRUST-issued certification, and each builds on the one below it. So if you’ve already done the work for an e1 or i1, that effort carries forward. Only the r2 can also produce a certification against the NIST Cybersecurity Framework.

The scoring is where HITRUST pulls away from a checkbox exercise. Controls are graded on a maturity rubric, not a simple yes-or-no test. Your vendor has to show that a control is documented, implemented, and actually operating, not just written into a policy.

Payers increasingly require HITRUST because it takes the guesswork out of vendor evaluation. A “HIPAA-compliant” claim is self-declared and unaudited. Two vendors can both call themselves HIPAA-compliant while running very different control programs, and the health plan has no standardized way to compare them. When both vendors are printing EOBs with diagnosis codes and member IDs, that gap in visibility is a real problem. HITRUST certification replaces the guesswork with a validated, third-party result.

The financial stakes back that up. Healthcare has recorded the highest average data breach cost of any industry for the fourteenth consecutive year, at $7.42 million per breach in IBM’s 2025 Cost of a Data Breach Report. Think about what that means for mail. A vendor printing and mailing Explanation of Benefits statements, member ID cards, or claims correspondence handles names, addresses, member IDs, and diagnosis codes on every piece. That vendor is a business associate under HIPAA, and its weaknesses become the health plan’s liability. (For more on what makes a mailing partner audit-ready, see our guide to compliance mail for regulated industries.)

HIPAA enforcement adds another layer. According to the HHS Office for Civil Rights’ 2024 Report to Congress, 663 large breaches were reported in 2024 alone, exposing the records of nearly 243 million individuals. HIPAA penalties are set in four tiers by culpability, each with an annual cap that can reach over $2 million per violation category. Now picture a print run of 500,000 EOB statements. That’s 500,000 records with PHI on the production floor, in the inserter, and in the mail stream. A payer that hands that volume to an unvetted mail vendor inherits exposure it can’t easily quantify. Requiring HITRUST is how large plans shift that risk into something measurable and certified.

For most vendor relationships, a SOC 2 Type II report will do the job. But when PHI is handled on behalf of a payer, HITRUST is often the requirement. The dividing line usually comes down to whether regulated health data and a payer’s own compliance obligations are in play.

Use this decision guide when evaluating a mail vendor:

There’s a key distinction worth understanding. SOC 2 is an attestation: a CPA firm expresses an opinion against the AICPA Trust Services Criteria, and there’s no certificate to pass or fail. HITRUST is a certification: you meet the threshold and HITRUST issues the credential. Payers who want a clear yes-or-no answer instead of an auditor’s narrative to interpret tend to prefer the certification.

The good news is the two aren’t mutually exclusive. Many vendors maintain a SOC 2 report for general enterprise customers and a HITRUST certification for their healthcare book of business. The frameworks overlap heavily, so the second one takes less effort once the control program is already in place.

Here’s the bottom line: when your print and mail partner handles PHI, its compliance posture becomes yours. A vendor that routes data through outside subcontractors multiplies the points where risk creeps in.

Mailing.com keeps print and mail in-house, so the chain of custody for PHI stays under one roof with a single accountable team. You can see how that model works across healthcare programs on our healthcare mail production page. That’s exactly what payers are looking for when they bring up HITRUST and SOC 2 in a vendor questionnaire: fewer handoffs, controls you can point to, and evidence a compliance reviewer can accept without reinterpreting it.

No. HIPAA is a federal law that sets mandatory standards for protecting PHI, enforced by the HHS Office for Civil Rights. HITRUST is a voluntary certification you earn against the HITRUST CSF, a framework that incorporates HIPAA requirements along with NIST and ISO 27001. Being HITRUST-certified demonstrates HIPAA controls, but HITRUST itself is not a law. For a closer look at what HIPAA compliance actually requires of a mail vendor, see our guide to HIPAA-compliant direct mail for healthcare.

Not directly. SOC 2 is an attestation against the AICPA Trust Services Criteria, and its standard criteria aren’t written around HIPAA. A SOC 2 report can include a HIPAA-mapped section, but it remains an auditor’s opinion rather than a compliance certificate. When a mail vendor is handling PHI on printed pieces, many payers prefer HITRUST because it maps HIPAA controls explicitly.

It depends on the payer’s requirements and the volume of PHI flowing through the mail operation. The r2 assessment is the most rigorous, and it’s the one large health plans most often specify for vendors printing and mailing high volumes of member-facing documents. The e1 and i1 levels suit lower-risk profiles, and because each level builds on the one below it, a mail vendor can start smaller and work up as the book of healthcare business grows.

Yes, and many mail vendors do exactly that. A SOC 2 report satisfies general enterprise customers who need print and mail services, while HITRUST certification satisfies the healthcare payers who require stricter PHI protections. Because both draw on overlapping controls, maintaining the second takes less work once the first is in place.
