5 Steps to Evaluate SOC 2 Reports for Vendors
Post Summary
When evaluating SOC 2 reports for vendors, especially in healthcare, the goal is to ensure data security and compliance with HIPAA standards. SOC 2 reports assess key areas like security, confidentiality, and privacy, making them a valuable tool for managing third-party risks. Here's how to evaluate them effectively:
- Check Scope and Objectives: Ensure the report covers all systems and services handling Protected Health Information (PHI). Watch for exclusions or carve-outs that might leave gaps in protection.
- Review the Auditor’s Opinion and Report Type: Focus on SOC 2 Type II reports, which assess controls over time. Look for an unqualified opinion for assurance that controls are functioning properly.
- Analyze Management Assertions: Verify the vendor’s stated scope matches their services. Be cautious of exclusions and ensure subservice organizations are accounted for.
- Examine Controls and Testing: Evaluate how controls are designed and tested, prioritizing areas like encryption, access management, and incident response.
- Assess Results and Deficiencies: Identify any control failures or gaps. Ensure the report is recent (within the last 12 months) and request a bridge letter if needed.
SOC 2 reports simplify vendor evaluations by aligning their controls with your compliance needs. Tools like Censinet RiskOps™ can further streamline this process, saving time while maintaining focus on PHI security.

Step 1: Verify the Report's Scope and Objectives
Start by confirming exactly what the SOC 2 report covers. SOC 2 audits can vary significantly - some vendors might focus on specific systems or services, leaving other critical areas unchecked. Begin by examining the systems and infrastructure included in the audit. This may involve servers, routers, EHR systems, or cloud environments where PHI (Protected Health Information) is handled.
Next, ensure that all services involving PHI are included in the scope. This means checking how data is collected, stored, processed, and transmitted. Pay close attention to data flows - understand how information moves within the vendor's organization and identify any weak spots in protection. Be on the lookout for carve-outs, where certain subservice organizations or vendors are excluded from the audit. If a vendor with access to your PHI is carved out, it’s a serious concern that requires further investigation.
Once you’ve verified the report’s scope, you can move on to reviewing the specific Trust Services Criteria (TSC). Using a SOC 2 audit documentation checklist can help ensure no critical details are missed during this review.
Review the Trust Services Criteria (TSC)
After confirming the scope, dive into the Trust Services Criteria covered by the audit. SOC 2 reports can address up to five TSC categories, but not all vendors include every one. At a minimum, Security is mandatory. However, for healthcare organizations, Privacy and Confidentiality are especially important to meet HIPAA requirements.
| TSC Category | Relevance for Healthcare Organizations |
|---|---|
| Security | Essential for protecting systems against unauthorized physical or logical access. |
| Availability | Ensures systems remain operational for patient care and meet reliability needs. |
| Processing Integrity | Confirms that medical data is processed completely, accurately, and with proper authorization. |
| Confidentiality | Safeguards PHI and other sensitive data from unauthorized disclosure using methods like encryption. |
| Privacy | Ensures adherence to HIPAA Privacy Rules. |
Dave Zuk from IS Partners explains, "The best method [to determine scope] is to identify your industry/organizational needs and associated risks" [1].
For healthcare providers, this means prioritizing criteria that directly address PHI security and compliance.
Confirm Alignment with PHI Handling and Compliance Requirements
Once you’ve identified the relevant TSC categories, map them to your HIPAA compliance needs. This helps reduce redundant compliance work and clarifies how the vendor’s controls align with your regulatory requirements. Check the report for Complementary User Entity Controls (CUECs) - these are responsibilities the vendor expects you to handle, like enforcing access controls or implementing encryption.
A well-documented SOC 2 Type II report can often replace lengthy vendor questionnaires [2], saving your team valuable time during HIPAA-compliant vendor risk management and due diligence. By confirming the report’s scope and its alignment with compliance needs, you’ll establish a solid foundation for evaluating the vendor. For even greater efficiency, tools like Censinet RiskOps™ can help streamline the process by mapping SOC 2 controls directly to HIPAA and other regulatory frameworks.
Step 2: Review the Auditor's Opinion and Report Type
The next step is to closely examine the auditor's opinion and the type of SOC 2 report provided. These elements play a key role in determining how much trust you can place in the vendor's controls for safeguarding PHI (Protected Health Information).
Understand the Difference Between Type I and Type II Reports
SOC 2 reports come in two formats, and the distinction is particularly important for healthcare organizations. Type I reports provide a snapshot of the vendor's controls at a specific point in time, while Type II reports evaluate how those controls perform over a longer period.
"A SOC 2 Type 1 report is like a single, perfectly staged photo of a secure house... A SOC 2 Type 2 report, however, is the continuous security camera footage from the last six months."
– Authoritative Source, SOC2Auditors.org [4]
For vendors handling PHI, a Type II report is typically the baseline expectation. It requires a minimum observation period of six months, giving a more comprehensive view of how controls operate over time. In fact, by 2026, 78% of enterprise clients required a SOC 2 Type II report from their vendors [4]. Lliam Holmes, CEO of MIS Solutions, also highlighted this preference: "Most customers expect a Type II report, not just Type I, when evaluating vendor security posture" [3].
Assess the Auditor's Opinion
Once you've identified the report type, turn your attention to the auditor's opinion, which is usually located near the beginning of the report. This section reveals whether the vendor's controls meet the required criteria. Here’s what the different opinions mean:
- Unqualified opinion: Often called a "clean" opinion, this indicates the controls are properly designed and functioning effectively without major concerns. This is what you want to see.
- Qualified opinion: This points to specific issues. Check the "Basis for Qualified Opinion" section to understand any control failures and their potential impact on PHI security.
- Adverse opinion: A serious red flag. This means the controls are not adequately designed or functioning as intended.
- Disclaimer: Another major concern. It indicates the auditor couldn’t gather enough evidence to form an opinion, which raises questions about the vendor’s transparency or maturity.
To ensure the report's credibility, verify that it was issued by a licensed CPA firm, as required by AICPA standards [5] [6]. You can confirm the firm’s credentials through NASBA and AICPA peer review records. Licensed CPA firms must undergo peer reviews every three years [6], so a firm without a current peer review rating may signal potential issues with audit quality.
Step 3: Review the Vendor's Management Assertion
After examining the auditor's opinion, the next step is to review the vendor's management assertion. This document outlines the vendor's declared control environment and scope of responsibility, setting the foundation for the auditor's evaluation. For healthcare organizations, it’s especially important to ensure that the vendor's stated scope aligns with the services they provide and the required standards for protecting PHI (Protected Health Information).
Take time to cross-check the assertion's scope and reporting period against the auditor's report. Both should cover the same systems, services, and timeframe. For example, if you’re outsourcing EHR (Electronic Health Record) data storage, confirm that the specific application handling PHI is explicitly included.
"A common mistake is assuming a vendor's overall compliance certification automatically covers the specific product module you are buying. Always verify the scope of the audit report." – Priyanshu Anand, Technology Match [8]
This step ensures the audit findings are relevant and trustworthy.
Be alert for exclusionary phrases like "except for" or "not including", as these may indicate gaps in PHI protection. Venminder experts emphasize the importance of addressing such language:
"Management's assertion may contain exclusionary language, such as 'except for' or 'not including,' which should warrant additional scrutiny." – Venminder [7]
If you spot these clauses, don’t hesitate to ask for more details. Request a written explanation or a bridge letter to clarify how these exclusions could affect your HIPAA compliance.
Another critical aspect to review is whether subservice organizations are included or excluded in the vendor's scope. If excluded, you’ll need separate SOC 2 verification for those entities. Vendors may use an "inclusive" approach (covering subservice organizations) or a "carved-out" approach (excluding them). This distinction significantly impacts the vendor's control environment and your compliance responsibilities [8][9].
Finally, review any Complementary User Entity Controls (CUECs) listed in the assertion. These controls outline security responsibilities assigned to your organization. Missing or overlooking these could leave PHI vulnerable.
Step 4: Examine Control Descriptions and Testing Procedures
After reviewing the management assertion, the next step is to dive into the control descriptions and the auditor's testing procedures. This phase is all about validating whether the controls are not only in place but are also functioning effectively - especially when it comes to safeguarding PHI.
It's important to understand the distinction between Type I and Type II reports. While Type I reports verify the design of controls at a specific point in time, Type II reports go further by assessing their operational effectiveness over a period of 6–12 months. This extended evaluation provides a more comprehensive assurance of how well PHI is managed [10][12].
"Type I testing looks at an example or single instance, while Type II testing is more comprehensive, looking at evidence across the entire audit period by sampling from the complete populations, where applicable." – IS Partners [10]
Ensuring the Testing Period Matches Your Needs
The timing of the testing period is critical. For instance, if you're using a vendor to handle PHI starting in January 2025, but their report only covers the second half of 2024, there's a clear gap in assurance. Similarly, if a report is over a year old, you should request a Bridge Letter from the vendor. This letter confirms that no significant changes have occurred since the audit was completed [10]. Keeping the testing period aligned with your operational timeline ensures you're relying on up-to-date and relevant data to protect PHI.
Focus on Healthcare-Specific Controls
Once you've confirmed the testing period aligns with your risk window, shift your attention to controls that are especially critical for healthcare organizations. Not all controls are equally important, so prioritize those directly tied to PHI protection and HIPAA compliance. Key areas to focus on include:
- Encryption: Ensure data is encrypted both at rest and in transit.
- Access Management: Verify that access is restricted to the minimum necessary, with measures like multi-factor authentication for administrative access.
- Incident Response Procedures: Check that these procedures are detailed and tested regularly [11][12].
Avoid vague language in control descriptions. For example, "appropriate security measures" isn't enough. Look for specific details about encryption protocols, access control mechanisms, and how incident response plans are implemented and maintained.
Review Testing Methods and Results
The reliability of an audit report often hinges on the testing methods used. Re-performance is one of the most reliable techniques. With this method, the auditor independently executes the control to verify its effectiveness. For example, they might try to access a restricted PHI database to confirm that access controls are functioning as intended [10].
Additionally, pay close attention to the sample sizes and populations tested. A Type II report should reflect comprehensive sampling across the entire audit period, rather than isolated examples. Larger and more representative sample sizes provide stronger evidence of consistent control performance. These details not only enhance the credibility of the report but also give you a clearer picture of the vendor's ability to manage risk effectively [10].
Step 5: Evaluate Test Results, Deficiencies, and Report Date
The final step is to carefully assess the test results, identify any deficiencies, and confirm the report's date. This process helps determine whether the vendor's controls function as intended or if there are gaps that could jeopardize Protected Health Information (PHI) and increase enterprise risk.
Identify and Address Control Deficiencies
Start by reviewing the auditor's opinion. An unqualified opinion signals that the controls are effective. On the other hand, opinions like qualified, disclaimer, or adverse should raise concerns. These opinions suggest issues such as control failures or insufficient evidence to verify effectiveness[7].
"Words like 'misrepresentation' or 'inadequate' are red flags that point to inaccuracies or weaknesses in the vendor's control environment." – Venminder Experts[7]
Next, dig into the Type II testing matrix. This section outlines which controls were tested, how they were tested, and the results. Pay close attention to any exceptions or deficiencies. These indicate moments where controls didn’t perform as expected[9, 18]. It’s important to distinguish between isolated incidents and more serious, systemic problems[14].
When evaluating exceptions, consider key questions: Were findings reported? Are exceptions repeated? How do they affect PHI? Are there mitigating controls in place? Did management address the issues[14]? For example, if a vendor fails to immediately remove a terminated employee's access to an application, check whether their access to the primary network (e.g., Active Directory) was revoked. Such mitigating actions could reduce the associated risk[14].
Look for phrases like "except for" or "not including" in the management assertion. These can signal exclusions in the controls. Management should also provide a clear plan for addressing or remediating any deficiencies[9, 18].
Here’s a quick breakdown of opinion types and their implications:
| Opinion Type | Meaning for Healthcare Risk Posture |
|---|---|
| Unqualified | Controls are accurately described, properly designed, and working effectively. |
| Qualified | One or more controls failed or didn’t work as designed; requires immediate investigation. |
| Disclaimer | Insufficient evidence was provided to assess controls, indicating a high level of risk. |
| Adverse | Major weaknesses were identified, suggesting potential misrepresentation of the control environment. |
Once you’ve addressed any deficiencies, shift your attention to verifying the report's date to ensure it reflects the current risk landscape.
Verify the Report's Date
Checking the report's date is just as important as reviewing its content. A SOC 2 report should be issued within the last 12 months to ensure it reflects the vendor’s current control environment[13]. Older reports may not account for significant changes, such as mergers, new cloud providers, or updated services, which could alter the risk profile[13].
"It's concerning if a critical vendor cannot provide a current SOC report, as this raises questions about their control environment and overall security posture." – Jena Andrews, CISA, PMP, IS Partners LLC[13]
Integrating SOC 2 Evaluations into Healthcare Risk Management
Incorporating SOC 2 evaluations into your healthcare risk management strategy helps align vendor controls with your compliance needs, ensuring better protection for sensitive data.
Map SOC 2 TSC Coverage to Healthcare Requirements
Start by aligning the SOC 2 Trust Services Criteria (TSC) with your HIPAA compliance program. As of 2020, HIPAA regulations impacted at least 2.7 million healthcare organizations across the U.S.[15]. Conduct a crosswalk analysis to map SOC 2 controls to HIPAA standards. For example, the Security TSC in SOC 2 reports aligns with COSO’s five components: Control Environment, Risk Assessment, Control Activities, Information and Communication, and Monitoring Activities[16].
"The Security TSC (which all SOC 2 reports must include) is directly mapped to COSO's five components." – David Dunkelberger, CPA, IS Partners[16]
This alignment is crucial because auditors often assess internal controls using the COSO framework, making it easier to prepare for audits[16]. Considering that healthcare data breaches doubled between 2018 and 2021[17], ensuring vendor controls are aligned is essential for protecting PHI.

FAQs
What should I do if PHI-related systems are excluded from the SOC 2 scope?
If systems involving Protected Health Information (PHI) are left out of the SOC 2 scope, it’s important to document them separately. These systems play a crucial role in ensuring compliance and safeguarding sensitive data. Clearly outline the SOC 2 scope and apply robust privacy and security measures to these excluded systems. Key controls to consider include encryption, access restrictions, and continuous monitoring. This approach helps protect sensitive data while ensuring adherence to HIPAA and other regulatory requirements, even if these systems fall outside the SOC 2 audit boundaries.
When is a bridge letter needed for a SOC 2 report?
A bridge letter is used to address the gap between the end date of a SOC 2 report and when the next report becomes available. It serves as interim confirmation that the controls outlined in the SOC 2 report are still in place and functioning effectively during the gap. However, it’s important to note that a bridge letter doesn’t provide the same level of attestation or assurance as a full SOC 2 report.
How do I map SOC 2 controls to HIPAA requirements and CUECs?
When aligning SOC 2 controls with HIPAA requirements and CUECs, there are a few key steps to keep in mind:
- Compare objectives: Look for common ground in areas such as access control, encryption practices, and risk management. These shared goals can simplify the alignment process.
- Review controls: Identify any gaps where SOC 2 controls may not fully meet HIPAA's specific safeguards. This step ensures no critical requirements are overlooked.
- Document findings: Develop a unified framework that addresses both SOC 2 and HIPAA standards, making it easier to manage compliance across the board.
Leveraging tools like Censinet RiskOps™ can make this process smoother, helping you maintain compliance efficiently while reducing manual effort.
