What Type of Independent Assessments Do Managed Service Providers Complete and Why Do They Matter?

Organizations increasingly rely on managed service providers (MSPs) to operate, secure, and optimize critical technology environments. These providers often have privileged access to systems, data, and networks that directly affect operational resilience, regulatory compliance, and customer trust. Given this level of responsibility, independent assessments are vital for demonstrating that MSPs meet recognized standards for security, control, and governance. Understanding which assessments your MSP completes, and why they matter, helps organizations make informed vendor decisions and manage third-party risk more effectively.

What Are Independent Assessments?

Independent assessments are formal evaluations conducted by qualified third parties who are not involved in the MSP’s daily operations. Their purpose is to objectively review the provider’s controls, processes, and practices against established frameworks or regulatory requirements. Unlike internal reviews, independent assessments offer external validation, which is often required by regulators, auditors, insurers, and enterprise customers.

These assessments typically focus on areas such as information security, operational controls, privacy, and regulatory compliance. The scope and rigor of the assessment depend on the services the MSP provides and the industries it supports.

Common Independent Assessments Applicable to MSPs

SOC Reports

There are three Service Organization Control reports commonly issued by a CPA firm on the controls of a service organization, such as an MSP:

• SOC 1 – Evaluates controls relevant to financial reporting, and is issued in two forms: Type I, which assesses the design of controls at a specific point in time, and Type II, which evaluates both the design and operating effectiveness of controls over a defined period.
• SOC 2 – Examines controls related to the recognized set of Trust Services Criteria, which encompass controls related to the security, availability, processing integrity, confidentiality, and privacy of data. SOC 2 reports can also be issued as Type I or Type II reports.
• SOC 3 – A summarized, public-facing version of SOC 2 reports. They confirm that an MSP has been assessed against the Trust Services Criteria but do not include detailed control descriptions or test results.

SOC 1 and 2 reports also outline Complementary User Entity Controls (CUECs), which detail controls that the organization must implement so that the controls implemented by the MSP as defined in the SOC report operate as intended. 

ISO/IEC 27001 Certification

ISO/IEC 27001 is an international standard for information security management systems (ISMS). Certification demonstrates that an MSP has implemented and maintains a formal, risk-based information security management system (ISMS) that addresses governance, incident response, and continuous improvement.

Unlike point-in-time reports, ISO 27001 certification requires ongoing audits and recertification. This makes it a strong indicator of long-term commitment to security and process maturity, particularly for MSPs operating globally or supporting regulated industries.

PCI DSS Assessments

MSPs that store, process, or transmit cardholder data or can impact the security of cardholder data environments may be subject to Payment Card Industry (PCI) Data Security Standard (DSS) requirements. PCI DSS assessments evaluate technical and operational controls designed to protect cardholder data.

Depending on the MSP’s role, compliance may be demonstrated through a Report on Compliance (ROC) or Self-Assessment Questionnaire (SAQ) validated by a qualified security assessor.

Regulatory and Industry-Specific Assessments

Some MSPs complete assessments or align their controls with specific regulatory frameworks, depending on the clients and industries they serve. Examples include:

• HIPAA-related assessments for healthcare support services
• FedRAMP or NIST-based assessments for government or public sector environments
• Privacy-focused reviews aligned with data protection regulations

While these assessments vary in structure, they all serve the same purpose: demonstrating that the MSP understands and meets the compliance obligations of its customer base.

Why These Assessments Matter

Independent assessments provide objective evidence that an MSP has implemented appropriate controls to manage security, operational, and compliance risks. For organizations with formal vendor risk management programs, these reports are critical to due diligence, contract approval, and ongoing oversight. Without them, organizations must rely on self-attestations, which offer limited assurance and may increase the risk that control deficiencies go undetected.

These assessments also support audit and regulatory requirements by demonstrating effective oversight of third-party providers. Independent reports can be leveraged by internal auditors and external auditors and may support regulatory examinations, reducing duplicative testing and follow-up inquiries. This is especially important for organizations subject to financial reporting standards, data protection obligations, or public sector oversight.

Beyond compliance, independent assessments establish a baseline of expectations between the MSP and its customers. They clarify which controls are in place, how they are tested, and where responsibilities are shared, enabling more productive discussions around service levels, security, and incident response. By validating these controls through credible third parties, assessments reinforce trust and support business continuity for organizations that rely on external providers to support critical operations.

Using Assessment Results Effectively

Simply collecting assessment reports is not enough. Organizations should review them carefully, paying attention to the assessment period and report currency, any control exceptions or qualified opinions, management responses and remediation plans, and alignment between the MSP’s controls and organizational risk requirements.

In many cases, assessments should be incorporated into ongoing vendor monitoring and renewal decisions.

Limitations to Consider

It is important to be aware of the inherent limitations that may exist with certain assessments. Organizations should consider the scope of the assessment, including whether any subservice organizations are excluded. They should also consider any requirements related to CUECs that could impact the effectiveness of the controls tested if the CUECs are not implemented. Similarly, the report period should be considered, and if there is a gap between it and the review date, the report may not reflect current conditions. Evaluating bridge letters or other updates becomes critical.

Final Thoughts

Independent assessments are a cornerstone of effective managed services oversight. Whether through SOC reports, ISO certifications, or industry-specific evaluations, these assessments provide objective assurance that MSPs operate with appropriate controls, discipline, and accountability. Understanding which assessments your managed service providers complete and their importance enables stronger vendor governance, reduced risk, and greater confidence in the services that support your organization’s growth.
