For businesses across the Crown Dependencies, the conflict in the Middle East feels far removed. But cyber risk does not respect geography – the real exposure may be closer, and less visible, than you may assume.
“Risk is developing beneath the surface”
Recent guidance from the Jersey Cyber Security Centre (JCSC), alongside advice from the UK National Cyber Security Centre, suggests there has been no immediate spike in direct cyber-attacks linked to the Iran conflict. Guernsey cyber security partners have reported a similar picture, while the wider lessons on resilience and third-party risk are equally relevant to organisations across the Crown Dependencies.
That sounds reassuring, but it should not be overinterpreted. The more meaningful shift is not necessarily in the volume of attacks, but in how risk is developing beneath the surface.
A shift from direct to indirect risk
For most organisations, the primary exposure is unlikely to come from being directly targeted. It is far more likely to come through others. Firms with customers, suppliers or operations connected to the Middle East – particularly in financial services, telecoms and energy – may find themselves indirectly exposed to attacks on infrastructure in the region.
Data centres, telecom networks and cloud providers have all been targeted. If your business relies on any of them, even indirectly, you are part of that chain, often without realising it. The most immediate risk is not direct attack, but exposure through systems and suppliers you do not control.
Why traditional defences may not be enough
There is a more subtle shift underway, and it has practical implications for how organisations think about cyber defence. Internet restrictions in Iran mean much of its traffic is no longer visible in the usual way, with activity increasingly routed through other countries. In simple terms, potentially hostile traffic may now appear to originate from the UK, the US or Europe.
This creates an uncomfortable reality. Blocking traffic based on geography may no longer be effective in the way many organisations assume. The more relevant approach is behavioural, focusing on what looks unusual rather than where it appears to come from. For many organisations, that represents a meaningful step up in capability, and one that is not always fully in place.
The risk that may already be here
“Today’s threats do not always arrive from where they appear to come from”
There is also a visibility issue that organisations should not ignore. Restrictions on internet access inside Iran may reduce ordinary traffic, but they are less likely to prevent determined threat actors from operating. State-backed groups, criminal networks and technically capable operators typically have alternative routes, external infrastructure or third-party systems available to them.
That means reduced visibility should not be mistaken for reduced capability. In some cases, activity may simply be harder to attribute, harder to trace, or designed to appear as though it originates elsewhere.
The absence of obvious disruption today is not necessarily a sign of stability. It may simply reflect the fact that modern cyber activity is often obscured long before it is detected.
It’s a business issue, not just a technical one
What makes this relevant for organisations across the Crown Dependencies is not geopolitics, but dependency. Financial services firms operate across jurisdictions, rely on global infrastructure and depend heavily on third-party providers. That creates efficiency, but also introduces exposure that is often only partially understood.
A Guernsey-based telecoms provider, for example, may have no direct involvement in the Middle East, but could still depend on international routing agreements or upstream network providers that do. If those networks are disrupted or compromised, the impact is felt locally – not because the business was targeted, but because it was connected.
While critical infrastructure providers are an obvious focus, smaller organisations are not insulated from these dynamics. Supply chains are already under pressure, with disruption to semiconductor inputs feeding through into the cost and availability of technology. Cyber risk is no longer a standalone issue; it is part of broader operational resilience.
What businesses should actually do
The underlying advice is familiar, but events like this expose the gap between having controls in theory and relying on them in practice. Frameworks such as Cyber Essentials and the Cyber Assessment Framework remain relevant, but only where they are actively used to test and improve real-world resilience.
In practical terms, this means moving cyber risk out of the IT function and into regular leadership discussion, stress-testing incident response and business continuity plans under realistic conditions, and developing the ability to detect unusual behaviour rather than relying on outdated assumptions about where threats originate. It also means taking a harder look at third-party dependencies, particularly where critical services rely on providers outside the organisation’s immediate control.
The JCSC and its counterparts across the Crown Dependencies also continue to provide practical guidance tailored to local organisations.
None of this is new. What changes is how seriously it is treated when the external environment becomes less predictable.
The question businesses should be asking
Most organisations believe their cyber controls are ‘good enough’, but that assumption is rarely tested in comfortable conditions. What events like this highlight is not necessarily a surge in attacks, but a shift in how they are delivered, how they are disguised, and how easily they can bypass outdated assumptions.
For businesses across the Crown Dependencies, the more relevant question is not whether this conflict will directly affect them. It is whether their exposure to global systems is greater than they think, and whether their controls are designed for how risk now behaves rather than how it used to.
Because the risk is not always where the conflict is happening.
