Understanding Third-Party Assurance Information.

Organizations rely on third-party vendors for critical services — from cloud infrastructure and data processing to customer support and security operations.

To assess whether these vendors can be trusted, organizations depend on third-party assurance artifacts: independent reports and certifications that evaluate a vendor’s controls, security posture, and compliance practices.

Why Third-Party Assurance matters.

Risk management

Third-party assurance artifacts help organizations identify and manage risks associated with outsourcing critical services.

Trust & transparency

Independent assessments provide confidence that vendors are operating as expected — beyond marketing claims or self-attestations.

Regulatory expectations

Many industries require organizations to demonstrate that their vendors meet specific security and compliance standards.

Where things break down.

While third-party assurance artifacts are essential, they are often difficult to interpret in practice.

Most reports are:

  • Long and highly technical

  • Written for auditors, not operators

  • Inconsistent across vendors and frameworks

As a result, teams spend significant time reviewing documents that still don’t clearly answer a critical question:

Can we trust this vendor — and why?

Common Third-Party Assurance artifacts:

SOC reports

SOC reports are independent assessments of a service organization’s internal controls, issued under standards defined by the AICPA.

They are among the most widely used assurance artifacts for evaluating third-party risk.

  • SOC 1 – Focuses on controls relevant to financial reporting

  • SOC 2 – Evaluates controls related to security, availability, confidentiality, processing integrity, and privacy

  • SOC 3 – A public-facing summary of SOC 2 results

Why SOC reports are challenging:
They are comprehensive, technical, and require expertise to interpret consistently.

ISO Certifications

ISO certifications demonstrate that an organization follows internationally recognized management and security standards.

Common examples include:

  • ISO 27001 – Information security management

  • ISO 9001 – Quality management

  • ISO 22301 – Business continuity management

ISO certifications indicate maturity, but often provide less operational detail than SOC reports.

PCI DSS

PCI DSS applies to organizations that store, process, or transmit payment card data.

It establishes baseline security requirements to protect cardholder information and reduce fraud risk.

Understanding assurance artifacts is essential — interpreting them consistently is the hard part.
