ISO 22301: Business Continuity Management That Works
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
| Metric | Answers |
|---|---|
| RTO — Recovery Time Objective | How fast must this activity be back? |
| RPO — Recovery Point Objective | How much data can we afford to lose? |
| MTPD — Max Tolerable Period of Disruption | When 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.
