Scope and applicability

Information security management system certification

Usually voluntary, certification may be required by customers, tenders or supply chains. ISO does not issue certificates; check the certification body's accreditation and customer acceptance.

Korean certification schemes and international standards are different. A translated guide does not extend a Korean certificate to other countries. Confirm the target market, product classification and current requirements with the relevant body.

Who this is for

  • SaaS vendors serving international enterprises
  • Organizations standardizing security operations
  • Teams scoping multiple sites and services

Questions and answers

Must every Annex A control be applied?

Determine necessary controls through risk assessment and compare against reference controls to explain omissions and applicability.

Does this replace Korean ISMS obligations?

No automatic substitution applies; Korean statutory requirements are assessed under the Korean scheme.

Why do quotations differ?

Advisory work, full implementation and audit-inclusive packages differ. Compare staffing, sites, services, travel and surveillance consistently.
