An ISO Certification Audit is the official Audit performed by a ISO Certification Body or Registrar that determines if an organization has met the ISO Standard’s Generic Requirements they intend to certify to (Example:  ISO 27001, ISO 22301, ISO 9001, ISO 42001, etc).  Upon successful completion, an organization will receive a ISO Certificate from the Certification Body or Registrar with their name, date of certification and “scope of registration” (what was audited).
