Securing maritime digital infrastructure

As vessels become increasingly connected, the risk of cyber incidents grows – making cybersecurity a critical foundation for safe and resilient operations.

With operational technology (OT) and information technology (IT) systems increasingly intertwined, a breach can impact not only data integrity but also vessel safety and business continuity.

Strengthening digital defenses across connected systems

In the age of smart vessels and autonomous technologies, maintaining secure, reliable digital infrastructure is more important than ever. Effective cybersecurity controls safeguard both onboard systems and the networks that connect ships to shore. The convergence of IT and OT demands a unified approach that includes secure system design, constant monitoring, and rapid incident response to protect core operational systems such as propulsion, communication, and navigation.

Regulatory alignment for trusted digital transformation 

Cybersecurity in maritime is no longer optional – it is essential. Regulatory frameworks such as IMO MSC.428(98), IACS UR E26/E27, and the EU’s NIS2 Directive mandate robust cyber risk management across all levels of vessel design and operation.

DNV’s ‘Cyber Secure’ class notation provides a structured approach to verifying cyber resilience, covering essential systems like propulsion, navigation, and communication, and aligns closely with the latest IACS unified requirements (URs) on cybersecurity.

Building digital resilience beyond technology

True resilience in maritime digital systems requires more than software or firewalls – it requires operational discipline and continuous improvement. Shipowners and operators must integrate digital cybersecurity into their management practices by strengthening crew training, updating incident response protocols, and embedding digital risk awareness into company culture. This strategic approach empowers organizations to identify, prevent and recover from incidents that could disrupt digital ecosystems.
