Modern vessels operate as interconnected IT and OT environments. Navigation systems, machinery, business applications and crew networks increasingly rely on continuous connectivity to shore, vendors and cloud platforms. NexusOcean approaches cybersecurity as an integral part of maritime operations, focused on protection, control and compliance without adding operational complexity.
Rather than deploying isolated security products, we integrate cybersecurity directly into the onboard network architecture. This ensures risks are managed structurally, not reactively, and responsibilities remain clear for fleet, IT and operations teams.
What this delivers:
Integrated design: Security is embedded into network architecture and managed alongside connectivity and IT.
Next-generation firewalls: Firewalls manage traffic, inspect data flows and block malicious activity.
Network segmentation: Clear separation of IT, OT and crew networks limits incidents and protects critical systems.
Continuous monitoring: SOC as a Service provides round-the-clock oversight and escalation by specialists.
Compliance support: Embedded controls and documentation help meet regulatory requirements without introducing fragmented tools.
Cybersecurity as part of the network design
Cybersecurity at sea is not a standalone layer. It must be embedded into how networks are designed, segmented and managed. NexusOcean integrates security controls into the same framework that manages connectivity and IT, providing consistent policies, visibility and accountability across vessels and fleets.
This approach reduces blind spots, prevents shadow IT and avoids dependence on ad-hoc security add-ons.
Next-generation firewalls and intrusion prevention
NexusOcean deploys enterprise-grade next-generation firewalls as the foundation of onboard cybersecurity. These systems control traffic between ship and shore, inspect data flows and actively block malicious activity through integrated intrusion prevention.
Firewalls are configured to protect both IT and operational systems, ensuring that increased bandwidth and remote access do not introduce additional risk. Central management enables consistent policies across the fleet while allowing adjustments based on vessel type or operational profile.
Network segmentation for IT, OT and crew
Effective cybersecurity depends on strict separation between different onboard networks. NexusOcean implements network segmentation to isolate operational technology, business systems and crew connectivity.
This ensures that crew usage cannot interfere with critical systems and that potential incidents are contained within a single segment. Segmentation also supports compliance with maritime cyber regulations and reduces the impact of human error, one of the most common attack vectors onboard.
Continuous monitoring and SOCaaS
Cyber threats evolve continuously, while onboard IT resources remain limited. NexusOcean therefore provides security monitoring through SOCaaS, enabling continuous oversight without requiring dedicated personnel onboard or ashore.
Security events are monitored, analysed and escalated according to agreed procedures. This provides fleet managers and IT teams with assurance that incidents are detected early and handled by specialists who understand maritime environments.
Compliance without operational burden
Cybersecurity requirements from regulators, class and insurers continue to increase. NexusOcean supports compliance by embedding security controls into standard operating environments and providing documentation, visibility and audit support when required.
This allows fleets to meet regulatory expectations without introducing fragmented tools or additional workload for crew and shore staff.
Integrated cybersecurity protects maritime operations without adding complexity.
Through embedded design, advanced firewalls, segmentation, continuous monitoring and compliance support, NexusOcean enables fleets to operate securely and confidently.
