Maritime Cybersecurity Services for Ships, Ports & Maritime Infrastructure
Protect shipboard IT and OT, navigation systems, vessel networks,
shore infrastructure, maritime applications and connected port
environments with risk-based cybersecurity assessment, penetration
testing, OT security, compliance and cyber resilience services.
Cybersecurity for an industry where digital risk can become operational risk.
Modern maritime operations depend on interconnected information
technology, operational technology, navigation, communications,
cargo and shore-based systems.
As vessels, ports and maritime businesses become more connected,
cybersecurity must extend beyond traditional enterprise IT.
A weakness in an exposed application, remote-access channel,
network, onboard system or third-party connection can affect
confidentiality, integrity, availability and operational resilience.
Assess vessel and shore-based attack surfaces.
Evaluate connected IT, OT, applications and networks.
Prioritize risks according to operational impact.
Maritime Threat Landscape
Where maritime cyber risk can originate
Maritime environments combine enterprise IT, shipboard operational
systems, communications, third parties and physical operations.
Effective maritime cybersecurity therefore considers both cyber
exposure and operational impact.
Shipboard IT & OT
Connected navigation, engineering, cargo and operational systems can create attack paths between environments.
Ship-to-Shore Connectivity
VSAT, remote access, fleet management and shore connectivity expand the maritime attack surface.
Navigation Systems
Navigation-related technologies require protection against unauthorized access, manipulation and availability risks.
Cargo & Port Systems
Cargo management, terminal applications and connected logistics platforms introduce additional digital dependencies.
Crew & Human Factors
Phishing, removable media, weak credentials, unauthorized devices and social engineering can become entry points.
Third-Party Dependencies
Vendors, equipment providers, shipyards, integrators and remote support channels can introduce supply-chain risk.

Maritime IT & OT Security
Protect the technology that keeps maritime operations moving.
Maritime cybersecurity is not limited to corporate networks.
Connected vessels can combine enterprise IT with operational
technology supporting navigation, communications, machinery,
propulsion, cargo and other critical functions.
Security assessments should therefore consider connectivity,
segmentation, privileged access, remote support, third-party
dependencies and the operational consequences of a security event.

Maritime Cybersecurity FAQ
Frequently Asked Questions About Maritime Cybersecurity
Find answers to common questions about maritime cybersecurity,
vessel security assessments, IT and OT environments, IACS
requirements and maritime cyber risk management.
Maritime cybersecurity protects the information technology (IT),
operational technology (OT), connected systems, networks,
applications and data used across ships, ports, maritime
operators and supply chains from cyber threats. It combines
cyber risk management, security assessment, technical testing
and resilience measures to reduce the potential impact of cyber
incidents on safety, operations and business continuity.
A maritime cybersecurity assessment can evaluate vessel and
shore-based IT and OT environments, network architecture,
segmentation, remote access, connected systems, applications,
cloud services, third-party connections and security controls.
Depending on the approved scope, it may also assess navigation,
communication, cargo, engineering and other operational systems
to identify vulnerabilities, cyber risks and potential attack paths.
Depending on vessel architecture and approved scope, a vessel
cybersecurity assessment may cover ECDIS, AIS, GNSS, radar, VDR,
GMDSS, VSAT, onboard networks, cargo systems, engineering and
machinery systems, remote access, crew networks and ship-to-shore
connectivity. The assessment should also consider how these
systems interact with enterprise IT, OT and third-party services.
Yes. Maritime cybersecurity should consider both information
technology (IT) and operational technology (OT), including how
systems are connected and how a cyber incident could affect vessel
operations, safety or business continuity. Assessments may examine
network segmentation, remote access, system dependencies,
third-party connections and controls protecting critical
operational environments.
IACS UR E26 addresses the cyber resilience of ships, while UR E27
addresses the cyber resilience of onboard systems and equipment.
They establish cybersecurity requirements relevant to the design,
construction, integration and operation of applicable new ships
and onboard systems. The current revised requirements should be
considered when determining the cybersecurity expectations
applicable to a specific vessel, system or project.
Depending on the organization’s role, vessel type and scope,
relevant maritime cybersecurity requirements and standards may
include IMO maritime cyber risk management guidance, IMO
Resolution MSC.428(98), the ISM Code, IACS UR E26 and E27,
BIMCO industry guidance, ISO/IEC 27001, IEC 62443 for relevant
OT environments and applicable national cybersecurity
requirements. The appropriate requirements should be determined
based on the organization’s operational and regulatory context.
