ISO 22301 vs ISO 27001:
Which Do You Need?

ISO 22301:2019 is the standard for business continuity management systems (BCMS): it proves you can keep prioritised products and services running through disruption, built on a business impact analysis, RTO/RPO/MTPD targets, continuity plans, and a tested exercise programme. ISO 27001:2022 is the standard for information security management systems (ISMS): it proves you can protect the confidentiality, integrity, and availability of information, built on a risk assessment, the 93 Annex A controls, and a Statement of Applicability. One protects delivery, the other protects data — and most vendor-assessment programmes for financial institutions now ask about both.

No — they are separate, separately certifiable standards. The confusion comes from the overlap: ISO 27001:2022 Annex A includes control 5.29 (information security during disruption) and control 5.30 (ICT readiness for business continuity), which require continuity thinking inside the ISMS. But two controls are not a management system: ISO 22301 demands a full BIA, disruption risk assessment, resourced strategies, plans, and an exercise programme, each audited in its own right. An ISO 27001 certificate is evidence of security, not of continuity.

Follow the demand on your desk. A bank or financial regulator deadline (CBUAE, SAMA, APRA CPS 230) means ISO 22301 first, because the assessor wants continuity evidence and the date is contractual. Stalled enterprise deals and security questionnaires mean ISO 27001 first, because it answers the security section of nearly every questionnaire. If both pressures exist — common for vendors running critical services for financial institutions — an integrated build is the efficient route: one governance layer, both certificates, and no duplicated audit machinery.

Yes. Both standards follow the Annex SL high-level structure, so Clauses 4–7, 9, and 10 — context, leadership, planning, support, performance evaluation, and improvement — can be implemented once as a shared governance layer. What stays distinct is each standard’s operational core: the BIA, strategies, plans, and exercises for ISO 22301; the risk assessment, Statement of Applicability, and Annex A controls for ISO 27001. In practice an integrated management system carries one policy framework, one document-control system, one internal audit programme, and one management review serving both certificates.

Most accredited certification bodies offer integrated or coordinated audits covering both standards — sampling the shared governance clauses once and the two operational cores separately, which reduces total audit days against two standalone audits. Each standard still produces its own certificate on its own three-year cycle, and the bodies align surveillance visits where the cycles permit. TCSA coordinates body selection and scheduling so the combined audit lands before your hardest external deadline.

Like every TCSA engagement: custom-scoped, with a fixed, all-inclusive quote after a short scoping call — no hourly billing, no scope creep. Scope depends on headcount, sites, products in scope, and how much of either system already exists; an integrated build is quoted as one engagement because the shared governance layer is built once. The accredited certification body’s audit fees — whether integrated or separate — are quoted by that body, since the consultant and the certifier must remain independent.
