SOC 2

SOC 2 is an independent attestation report that evaluates and describes the design and operating effectiveness of a service organization’s controls related to the AICPA Trust Services Criteria: security, availability, processing integrity, confidentiality, and privacy. It is commonly used to assess cloud, IT, and managed service providers that support regulated or sensitive operations, including industrial and manufacturing environments.

A SOC 2 report is not a certification. Instead, an external auditor (CPA firm or equivalent) assesses the organization’s control environment against the selected criteria and issues a narrative report and opinion. Organizations can choose which of the Trust Services Criteria to include, although security is almost always in scope.

Type I vs. Type II

SOC 2 reports commonly appear in two forms:

• Type I: Evaluates the design of controls at a specific point in time.
• Type II: Evaluates both the design and operating effectiveness of controls over a defined review period (for example, 6 or 12 months).

In manufacturing and other regulated operations, SOC 2 Type II reports are more frequently requested because they provide evidence of control performance over time, not just point-in-time design.

Scope and relevance in industrial and regulated environments

For industrial and manufacturing organizations, SOC 2 reports are most relevant when assessing third-party providers that host or operate:

• Cloud-based MES, ERP, LIMS, QMS, or data historians
• IIoT and edge platforms that collect or process production data
• Managed infrastructure or security services supporting OT/IT
• Data lakes and analytics platforms used for production or quality data

The report typically includes system descriptions, defined control objectives and controls, testing procedures, and auditor test results. These sections are often used as input to vendor risk assessments, shared responsibility matrices, and mappings to frameworks such as NIST SP 800-53 or ISO 27001.

Operational use

In practice, SOC 2 reports are used to:

• Evaluate security and reliability of external service providers that support regulated manufacturing or critical processes
• Support audit readiness by providing third-party control evidence
• Inform internal control mappings, for example when determining which NIST SP 800-53 controls are implemented by a cloud provider vs. by the manufacturer
• Identify gaps where additional internal controls, configurations, or monitoring are required

The report itself does not guarantee compliance with any particular regulation. It is one evidence source that must be interpreted in the context of the organization’s own systems, responsibilities, and regulatory requirements.

Common confusion

• SOC vs. SOC 2: “SOC” is a family of reporting frameworks (SOC 1, SOC 2, SOC 3). SOC 2 specifically addresses Trust Services Criteria, not financial reporting.
• SOC 2 vs. SOC 1: SOC 1 focuses on controls relevant to financial reporting. SOC 2 focuses on security and related criteria. For manufacturing IT/OT and cloud services, SOC 2 is usually the more relevant report.
• Certification vs. attestation: SOC 2 is an attestation report, not a certification. Organizations cannot be “SOC 2 certified” in a formal sense; they can have a current SOC 2 Type I or Type II report.

Relation to the provided context

When mapping NIST SP 800-53 or similar control frameworks for cloud or hosted services, SOC 2 reports are often used alongside FedRAMP and ISO security documentation. They help clarify which controls are implemented by the service provider, which require customer configuration, and which remain the customer’s sole responsibility.
