The AICPA describes SOC as a suite of services CPAs provide on the controls of a service organization. A SOC 2 report addresses controls relevant to five categories: security, availability, processing integrity, confidentiality and privacy. The AICPA guide says customers and business partners need information about the design, operation and effectiveness of those controls.
Who reads the report on the buyer's side
Security, legal and procurement teams. Use of a SOC 2 report is generally restricted, so it goes out under NDA; the AICPA's SOC 3 is the general use version with less detail.
Until you have a report, the buyer judges you on questionnaires and documents, and a readiness plan with an audit date helps keep the deal moving.
