Business continuity is the discipline of ensuring an organisation can keep delivering its critical activities during and after a disruption, and ISO 22301 is the management-system standard that structures it. The connection to cybersecurity is direct: the most disruptive events many organisations now face are cyber incidents. A ransomware attack that encrypts production, a wiper that destroys infrastructure, or a breach that forces system isolation all become business continuity events the moment they affect the ability to operate. Without a BCMS, the response is improvised.
The standard follows the same plan-do-check-act shape as ISO 27001, and integrates cleanly alongside it. The core activity is the business impact analysis, which identifies the organisation's critical activities and, for each one, the maximum tolerable period of disruption — how long the organisation can survive without that activity before suffering irreversible harm. The analysis also identifies dependencies: the people, suppliers, systems, and facilities each critical activity relies on. The recovery time objectives derived from the BIA drive the continuity strategy.
The continuity strategy defines how the organisation will keep each critical activity running or restore it within its recovery time objective. Options include redundancy, alternative sites, alternative suppliers, degraded-mode operation, and manual workarounds, and the right answer is usually a combination. The strategy is documented in business continuity plans that are specific, actionable, and kept current — a plan that no one has read since it was written is worse than useless in an incident, because it gives false confidence.
Testing is where most continuity programmes fail and where ISO 22301 certification provides the most value. A plan that has never been exercised will not work. The standard requires exercising the BCMS at planned intervals, and certification audits examine the testing evidence. Exercises range from walkthroughs and tabletops — where the team discusses its response to a scenario — to full live exercises that actually invoke the continuity arrangements. Each exercise exposes gaps, drives improvements, and builds the muscle memory the team needs when a real incident occurs.
Passeca delivers business continuity and disaster recovery support aligned to ISO 22301: business impact analysis, continuity strategy, plan development, exercise design and facilitation, and the BCMS itself for organisations pursuing certification. For cyber-driven scenarios, this work is most effective when combined with incident response retainers and recovery capabilities — so that the technical containment and recovery and the business continuity response are coordinated rather than run as separate efforts.
