ISO 22301: Business Continuity Management That Works

10 June 2026·8 min read·Cyber Horizon Team

A ransomware hit, a cloud-region outage, a key supplier failing — resilience is no longer optional. ISO 22301 is the international standard for a Business Continuity Management System (BCMS): a structured way to keep critical operations running through disruption, and recover the rest quickly.

Start with the Business Impact Analysis

The BIA is the engine of the whole system. You identify your critical activities, the impact of losing them over time, and the dependencies behind them — people, systems, suppliers, facilities. Everything else flows from this.

Two numbers that define your strategy

MetricAnswers
RTO — Recovery Time ObjectiveHow fast must this activity be back?
RPO — Recovery Point ObjectiveHow much data can we afford to lose?
MTPD — Max Tolerable Period of DisruptionWhen does the damage become unacceptable?

Building the BCMS

Continuity strategies

How you’ll meet each RTO — failover, alternate sites, manual workarounds, supplier redundancy.

Continuity plans

Documented, role-based procedures people can follow under stress.

Exercising & testing

Tabletops and live tests that prove the plans work before a real event.

Continual improvement

Lessons from incidents and exercises fed back into the system.

Where it connects

22301 pairs naturally with ISO 27001 (incident management, availability) and with regulatory resilience regimes like DORA. The discipline is the same: know what’s critical, plan to keep it running, and prove the plan works.

The bottom line

ISO 22301 turns “we have a backup” into a tested, governed capability to survive disruption. The BIA tells you what matters; RTO/RPO set the bar; exercising proves you can clear it. A plan you’ve never tested isn’t a plan — it’s a hope.

Make resilience evidence-backed

Cyber Horizon tracks ISO 22301 controls, links continuity plans to your risk and incident data, and runs tabletop exercises — so your BCMS is tested, not theoretical.
