SOC 2 in brief

SOC 2 and vendor questionnaires explains SOC 2 for European SaaS: CPA attestation on Trust Services Criteria (security often leading). ISO 27001 certifies an ISMS — different proof, different market.

Type I vs Type II

Type I is design at a point in time; Type II is operation over a period (often 6–12 months). Enterprise buyers usually want Type II.

Evidence and combining with ISO

Map TSC controls to your ISO SoA and risk register. Share logging, access reviews and change records — avoid duplicate policies. Use one evidence map tagged per framework.

Common mistakes

Presenting SOC 2 as ISO; no period for Type II; evidence on personal drives; manual vendor questionnaires without a register.

Checklist

  • Choose Type I or II
  • Map TSC ↔ ISO controls
  • Shared evidence map
  • Readiness scan before audit
  • Link contracts and questionnaires
