Identify cyber risk across vessel OT and SCADA: engine control, cargo control, ballast water management, fuel monitoring, bridge integrated navigation. Codesecure runs OT-safe passive monitoring, configuration review and risk analysis aligned with IEC 62443, NIST 800-82 and IACS UR E27.
Maritime OT (Operational Technology) and SCADA (Supervisory Control and Data Acquisition) systems control the physical equipment that makes a vessel function: engine, propulsion, steering, cargo loading and discharge, ballast water management, fuel monitoring, alarm and monitoring, bridge integrated navigation. Failure or compromise of these systems has direct safety, environmental and commercial consequences.
Codesecure delivers maritime OT / SCADA assessment using an OT-safe methodology: passive packet capture on OT networks (no aggressive scanning), configuration and architecture review with vendor documentation, control / monitoring server hardening review, and risk analysis aligned with IEC 62443 industrial automation security, NIST SP 800-82 OT security, and IACS UR E27 ship-systems cyber resilience. Our consultants have IT, OT and maritime field experience.
Vessel OT was largely designed before cyber threats were considered. Legacy protocols (Modbus, NMEA 0183, NMEA 2000, J1939 marine) carry no authentication or encryption, default credentials are common on PLCs and controllers, and segmentation between OT and IT is often weak or absent. A single compromised crew laptop on the same flat network as engine controls is a real-world risk pattern.
OT assessment is also explicitly expected. IACS UR E27 makes cyber resilience of ship systems a class-society requirement for new builds. IMO MSC.428(98) expects vessel SMS to address cyber risks across the asset estate, which includes OT. Charterers (Shell, BP, ExxonMobil) include OT cyber in TMSA vetting questions. Without an assessment baseline, you cannot demonstrate due diligence.
Codesecure's maritime OT / SCADA assessment covers vessel-wide OT and SCADA estates:
45-minute call with our maritime OT lead. Bring your vessel type, OT system inventory and class-society requirements, leave with a phased assessment roadmap. Instant response, no delay.
Book Free Strategy CallEvery OT / SCADA Assessment engagement follows a 5-phase methodology aligned with IMO and IACS guidance:
Scoping call, NDA, vessel survey, OT system inventory, ROE for OT-safe testing, schedule alignment with port-call window.
Vendor documentation review, OT architecture mapping, segmentation analysis, configuration export review.
Port-call or planned-visit on-board phase. Passive packet capture on OT networks, HMI station review, controller config inspection.
Per-system risk register, mapping to IEC 62443 zones / conduits, NIST 800-82, IACS UR E27.
Class-society-aligned report with prioritised findings. Remediation guidance with vendor coordination. Optional retest.
Every OT / SCADA Assessment engagement ships with the same operational handoff:
Most maritime OT / SCADA assessments complete within 3-5 weeks per vessel. Instant response, no delay, kickoff scheduled same or next business day after scoping.
Scoping, NDA, vendor documentation review, OT architecture mapping, ROE.
Port-call on-board phase, passive capture, HMI / controller inspection.
Risk analysis, IEC 62443 mapping, class-society-aligned report, remediation support.
// Frameworks & Standards We Cover
30-minute call with our maritime OT lead. Discuss your vessel type, OT estate and class-society timelines with no sales pressure.
Schedule Free CallYes, with Codesecure's OT-safe methodology. We use passive packet capture only on production OT networks, never active scanning of PLCs or engine controllers in operation. Active testing, where required, is performed only in dry-dock, planned maintenance windows, or test environments with master / chief engineer approval.
Maritime OT assessment pricing varies by vessel type (tanker, container, bulk, LNG, cruise), OT estate complexity and number of vessels. We provide a fixed-fee scoped proposal within 24-48 hours of scoping. Fleet-wide engagements scale down per-vessel as we reuse architecture knowledge across sister ships.
Yes. DP-class vessels (DP1, DP2, DP3) get extended scope covering DP control system, reference systems (DGPS, hydroacoustic, fan beam, taut wire, etc.), thruster controls and DP HMI stations. We coordinate with the DP OEM (Kongsberg, Wartsila, Marine Technologies, etc.) on vendor-approved testing methods.
Instant response, no delay. We respond within an hour during business hours, send a fixed-fee scoped proposal in 24-48 hours under NDA, and start scoping same or next business day after sign-off.
Yes. Reports are aligned to IEC 62443, NIST 800-82, IACS UR E27, IMO MSC.428(98) and BIMCO Cyber Guidelines, and mapped to TMSA 3 Element 13. Reports are accepted by IRS, DNV, BV, LR, ABS and major charterer vetting programmes.
We assess offline systems via documentation review, configuration export inspection, and on-board controller examination. Even disconnected OT systems are at risk from USB-borne malware, vendor technician access and supply-chain compromise. The report covers offline-system risks explicitly.
Yes, via our Maritime SOC service. Passive OT monitoring can be deployed using purpose-built ICS/OT detection platforms (Nozomi, Claroty, Dragos) or Wazuh with OT-aware rules. Continuous monitoring complements point-in-time assessment.
