Maritime cyber risk is no longer a future concern or a purely technical issue. It is increasingly becoming an operational resilience challenge with direct implications for shipowners, insurers and the wider marine insurance market.
Shipping has always adapted to disruption. Wars, sanctions, regional instability and trade restrictions have repeatedly reshaped global trade patterns and vessel operations. Traditionally, marine insurance has responded through mechanisms such as war risk clauses, trading exclusions and revised underwriting strategies. Cyber risk, however, introduces a different type of exposure because digital systems are now deeply integrated into day-to-day vessel operations.
Modern ships rely heavily on interconnected technologies for navigation, cargo operations, communications, propulsion monitoring and shore-based coordination. As a result, cyber incidents are no longer confined to IT systems alone. They increasingly have the potential to disrupt operational continuity, decision-making and vessel safety.
Recent events have reinforced this trend. Reports of GPS spoofing and electronic interference in high-risk regions such as the Strait of Hormuz and the Red Sea have highlighted how geopolitical instability and digital vulnerability are becoming increasingly interconnected. At the same time, ransomware attacks targeting ports and logistics infrastructure continue to demonstrate the potential for operational disruption across the wider maritime supply chain.
For insurers, this creates a more complex risk environment. Over recent years, many traditional marine insurance structures have introduced cyber exclusions, particularly within hull and machinery cover, reflecting the challenges associated with systemic cyber exposure and attribution. However, the operational dependency on digital systems continues to grow, while dedicated cyber cover remains relatively limited across large parts of the global fleet. This creates a widening gap between exposure and protection.
The challenge for the industry is therefore not only technical preparedness but also operational resilience. Cyber resilience increasingly depends on practical awareness, contingency planning, crew preparedness and the ability to maintain safe operations during periods of degraded or disrupted digital capability.
As maritime operations continue to evolve, cyber risk must increasingly be viewed through the same lens as other operational risks affecting safety and continuity at sea. For the marine insurance market, this means continuing to strengthen dialogue, awareness and collaboration across the industry to ensure that resilience develops alongside technological dependence.
