Far fewer know whether it would [actually work ](https://deiterate.com/blog/2025/09/15/the-difference-between-passing-an-audit-and-being-compliant)during a real disruption. That’s the uncomfortable gap sitting underneath ISO 27001 **Control 5.30: ICT Readiness for Business Continuity**. In modern organisations, almost every critical business process now depends on technology in some way. And, simply having backups is not the same as being operationally ready. Think about it. Your organisation likely depends on technology for: When those systems fail, whether through cyber attack, outage, human error or supplier disruption, the organisation needs to know: what happens next? How will your organisation continue to function at optimum levels? That’s what this control is really about. ### **What Control 5.30 is Actually Asking** Control 5.30 requires organisations to ensure that information and communication technology (ICT) systems and supporting capabilities can be recovered and restored in line with business continuity requirements. In plain English: can the organisation continue operating when technology breaks? Not theoretically. Operationally. It is not just an IT exercise. It is a business continuity exercise. The control focuses on preparedness: ### **Where Organisations Usually Get this Wrong** A lot of organisations assume they are covered because backups exist, systems are cloud-hosted, or a provider has “high availability”. However, resilience is more than infrastructure redundancy. The real problems tend to appear in areas like: This becomes particularly obvious during ransomware incidents, cloud outages , identity platform failures or critical supplier disruptions. These instances are usually when organisations discover that, while there was a plan, this plan does not equate to real readiness. ### **The Cloud Myth** One of the biggest misconceptions in modern security is “We’re in the cloud, so business continuity is handled.” It isn’t. Cloud platforms improve resilience in many ways, but they do not remove responsibility. Organisations still need to understand: A SaaS platform can still fail, become unavailable, suffer data corruption or create dependency risk. Cloud changes the continuity model but it does not eliminate it. ### **What Good ICT Readiness Looks Like** Strong ICT readiness is not about eliminating disruption. It is about reducing uncertainty when disruption occurs. #### **1. Critical Systems are Clearly Identified** The organisation understands: #### **2. Recovery objectives are defined** Good continuity planning establishes Recovery Time Objectives (RTOs) and Recovery Point Objectives (RPOs). This means that organisations know how quickly systems need to recover, and how much data loss is acceptable. Without having these elements defined, recovery becomes guesswork. #### **3. Dependencies are Understood** Many organisations underestimate hidden dependencies: When one system fails, the ripple effects can be significant. #### **4. Restoration is Tested** This is where maturity really shows. [Backups that have never been restored are assumptions, rather than controls](https://deiterate.com/blog/2025/10/20/your-compliance-program-isnt-broken-its-fragmented). Well prepared organisations test restoration procedures, failover capability, recovery timing and communication processes. The first test should never happen during an actual incident. #### **5. The Business is Involved — Not Just IT** Business continuity is [not owned solely by technology teams.](https://deiterate.com/blog/2025/08/26/cybersecurity-isnt-just-for-the-tech-team-why-everyone-needs-to-own-it) The business needs to understand operational priorities, manual workarounds, communication expectations and acceptable downtime. Technology recovery and business recovery are connected. ### **Why this Control Matters Now** Operational resilience expectations are increasing rapidly. Customers, regulators and partners increasingly expect organisations to demonstrate resilience, recovery capability and continuity planning maturity. At the same time, the threat landscape is evolving: The question is no longer: “Do you have a continuity plan?” It is: “Can you recover when it matters?” ### **The Evidence Problem** Like many ISO 27001 controls, this Control is not just about intention. It is about evidence. Can the organisation demonstrate: Because during an audit — or a real incident — undocumented assumptions become visible very quickly. ### **Resilience is Not Built During a Crisis** Control 5.30 is often underestimated because it sits quietly in the background. Until something breaks. Then it becomes one of the most important controls in the organisation. Resilience is not built during a crisis. It is built beforehand through preparation, testing, ownership and operational clarity Organisations that handle disruption best are rarely the ones with perfect environments. They are the ones that prepared realistically for imperfect conditions. ### **Need Help Getting Your Ducks in a Row?** de.iterate helps organisations operationalise ISO 27001 by connecting policies, risks, evidence, controls and assurance activities into one practical management system. So business continuity becomes something you can manage, maintain and prove, rather than just document.
