SOC 2 vs ISO 27001 for vendor assessment

Different artifacts, different assurance

A SOC 2 Type II report describes control operation over a period and includes an auditor opinion. An ISO 27001 certificate confirms a management system was certified, with detail carried in the Statement of Applicability.

Mapping to one requirement set

Rather than treating each framework as a separate review, map both to the internal requirements you actually care about, then record which evidence satisfies each requirement.

Handling gaps

Where neither artifact covers a requirement, the gap itself is the finding. Record it with the missing evidence type so remediation has a clear ask.
