SOC 2 attestation in Tokyo at a glance
A foreign software company opening in Tokyo through the Asian-headquarters zone often brings its US or European customer base with it, and those customers already ask for a SOC 2 report. SOC 2 is an attestation, not a certificate: an independent licensed audit firm reports on whether controls meet the trust services criteria for security, and optionally availability, confidentiality, processing integrity or privacy. The Tokyo team supplies the evidence, and the earlier it is organised, the shorter the examination feels. Sterling's Tokyo office prepares your controls, policies and evidence in Effivity so the audit firm's examination runs smoothly, and the report stays entirely the audit firm's to issue.

SOC 2 in Tokyo: questions clients ask
When should a Tokyo software company move from ISO 27001 to SOC 2?
When customers outside Japan ask for a SOC 2 report in their security reviews. ISO 27001 gives a certified system; SOC 2 gives an independent auditor's report on controls over a stated period. The two share many controls, so firms holding one can reuse a good deal of the evidence for the other.
Who produces the SOC 2 report for a Tokyo company?
An independent licensed audit firm examines the controls and issues the report to your management. Sterling prepares the organisation beforehand through scoping, control design, evidence collection and readiness checks. It does not attest or issue the report, and that separation is what keeps the audit independent.
