ISO 22301 vs ISO 27001: Integrating BCMS and ISMS (Annex A 5.29/5.30)

ISO 22301 certifies a Business Continuity Management System. ISO/IEC 27001:2022 certifies an Information Security Management System. Both use the High-Level Structure, so integrated programmes are common — but scopes and outcomes differ.

ISO 27001:2022 bridge controls: Annex A 5.29 — information security during disruption; Annex A 5.30 — ICT readiness for business continuity. Use these when mapping ISMS controls to BCMS needs.

Comparison

Primary outcome — 22301: continuity of activities; 27001: confidentiality, integrity, availability of information
Core analysis — 22301: BIA + continuity risk; 27001: information security risk assessment
Plans — 22301: BCP / strategies / exercises (8.5); 27001: security controls + SoA (incl. 5.29 / 5.30)
Certification — both Stage 1 / Stage 2, typically 3-year cycles with surveillance

Integration Tips

Align scope statements and shared leadership clauses where practical
Reuse competence, documented information, internal audit, and management review cadences
Map A.5.29 / A.5.30 evidence to BCMS operational controls and DR capabilities
Keep BIA-driven recovery objectives visible to security architects

Frequently Asked Questions

Do we need both certificates?

Depends on customers and regulators. Many organisations certify 27001 first and add 22301 when continuity assurance is demanded.

Does 27001 certification prove 22301?

No. A.5.29 / A.5.30 help but do not replace a full BCMS against Clauses 4–10 of ISO 22301.

Same certification body?

Often efficient for integrated audits, but not required. Choose accredited CBs competent in both standards.
