Attacks on vessel OT systems
Compromise of ECDIS, propulsion, steering, power management, or cargo control systems through poorly segmented networks or remote access.
Cyber Security for Maritime & Shipping
Protecting vessels, OT systems, satellite communications, and port operations from modern cyber threats.
Cyber Defence for Maritime Operations
The maritime sector faces unique cyber challenges. Vessels depend on integrated OT systems, ECDIS navigation suites, satellite communication, propulsion management, cargo systems, and automated bridge controls. Shore operations rely on logistics platforms, cloud identity, port networks, and vessel tracking systems.
Cyber Defence provides comprehensive cyber security for maritime operators, shipping companies, superyacht fleets, port authorities, and offshore vessels. Our approach protects both IT and OT assets, ensuring operational continuity at sea and ashore.
Threats
Key cyber threats facing maritime operators
Maritime organisations are targeted for operational disruption, ransom, espionage, fraud, and supply-chain compromise. We protect against:
Satellite communication (SATCOM) compromise
Exploitation of satellite terminals, misconfigurations, weak authentication, or exposed management interfaces.
Phishing & crew targeting
Credential harvesting and malware campaigns exploiting crew rotation, payroll, port scheduling, or immigration workflows.
Ransomware & operational disruption
Attacks impacting bridge systems, logistics platforms, cargo terminals, or fleet management IT.
AIS & vessel tracking manipulation
Spoofing or manipulation of AIS, GPS, or vessel telemetry to disrupt navigation or hide vessel movements.
Supply-chain & shore side compromises
Attacks via port systems, logistics partners, marine service providers, and software update channels.
Services
How Cyber Defence supports maritime operators
We deliver cyber protection aligned to maritime operational realities – at sea and ashore.
SOC365 Maritime MDR
24/7 monitoring of vessel and onshore IT systems, including identity, VPN, SATCOM, and cloud platforms.
Threat Intelligence for Maritime
Monitoring for threats targeting maritime OT, AIS manipulation, vessel spoofing, dark web activity, and crew-targeting phishing.
OT & Vessel Penetration Testing
Testing of ECDIS, propulsion control, onboard IT/OT segmentation, and critical communication paths.
Incident Response for Maritime
Fast containment and investigation of cyber events affecting vessel operations, bridge systems, or port-side IT.
Engineering & Hardening
Secure configuration of SATCOM, vessel networks, Wi-Fi, remote access solutions, GPS/AIS equipment, and port connectivity.
Protecting maritime OT, vessel systems, and IT environments
Modern vessels combine OT, ICS, and traditional IT. Navigation systems, propulsion, ECDIS, power management, cargo control, environmental sensors, and safety systems often sit alongside crew networks, entertainment systems, satellite Internet, and remote access tools.
This creates cross-domain attack paths. Cyber Defence helps operators map these paths, segment OT from IT, monitor OT-friendly telemetry, and detect malicious activity before it affects vessel safety or operational continuity.
Outcomes
What maritime organisations gain
Cyber Defence supports safe, compliant, and uninterrupted operations at sea and ashore.
Reduced risk of navigation or OT disruption
Monitoring and segmentation reduce the likelihood of cyber incidents impacting safety-critical vessel systems.
Improved resilience for fleet and port operations
SOC365 enhances visibility across vessel IT, SATCOM, cloud identity, and port-side systems.
Alignment with IMO & maritime cyber guidelines
Support aligned to IMO 2021, ISPS, and best-practice maritime cyber frameworks.
Preparedness for major incidents
IR Retainers ensure contract-backed response for vessel or port-side cyber emergencies.
Protection against targeted crew phishing
Threat Intelligence identifies campaigns exploiting maritime rotations, visas, and port workflows.
A long-term maritime cyber partner
We support continuous improvement across IT, OT, and vessel environments.
