Secure your IT & OT.
Everywhere, always.
As organisations modernise and digitise their operations, often across remote sites, your digital and industrial systems (IT and OT) become increasingly vulnerable. It's time to defend your critical systems against increasingly threats and remain fully compliant.

Cyber threats evolve fast,
so must you.
Regulatory pressures are intensifying, with new data privacy laws and new cyber security requirements for IT and OT emerging worldwide. In the EU, the revised Network and Information Security Directive (NIS2) mandates stricter cyber security measures, with companies facing substantial penalties for non-compliance.
With our secure remote-access platform and industrial-grade cyber controls, you can ensure encrypted, compliant and resilient connectivity across your corporate and operational systems, including those in remote or distributed sites. That means preserving your data’s confidentiality, integrity and availability, and keeping operations running securely. Even under threat.

Guiding you towards complete cyber resilience.

MFA & Conditional Access
Stop credential theft before it starts with Marlink’s managed Multi-Factor Authentication, an essential layer of defence for the world’s most demanding operating environments. Weak or stolen passwords remain the leading cause of breaches, and MFA closes that gap by verifying every user with a second, trusted factor before access is granted. Built for your industry, our solution works reliably across low-bandwidth and intermittent connections, so security never depends on a perfect link. We handle deployment, policy configuration, and ongoing management, removing the burden from your team while strengthening protection across email, applications, and critical systems. Scalable across locations, Marlink’s MFA gives you confidence that only the right people reach your most sensitive assets, wherever they connect from.
Fully managed deployment and policy control, closing the number one cause of breaches: stolen credentials.

Marlink Privilege Remote Access (PRA)
Marlink’s Privilege Remote Access (PRA) solution protects IT and OT environments by securing remote connections, managing user privileges, and preventing credential misuse. As attackers increasingly exploit stolen logins rather than system vulnerabilities, PRA ensures that only authorised users gain access and that every session is monitored, controlled, and auditable. Through advanced authentication, least-privilege enforcement, and secure credential injection, Marlink PRA eliminates shared credentials and strengthens identity protection. It provides live session monitoring, recording, and auditing for full visibility and compliance with international standards.
Build for IT and OT
Keeping your operations efficient, compliant, and protected against evolving identity-based threats.
Network Detection & Response (NDR)
Marlink’s NDR provides the ultimate defence from within, continuously monitoring IT and OT networks to uncover hidden threats that firewalls and antivirus can’t detect.

Gain a clear understanding of your security posture with Marlink’s Security Assessments & Reviews, providing an independent view of security across both IT and OT environments. Our experts simulate real-world adversaries, testing your systems, networks, and configurations against the threats recognised in your industry. Rather than a generic checklist, you receive a practical, prioritised view of strengths, weaknesses, and exposure, translated into actionable recommendations for both business and technical teams. We assess your environments, taking into account the operational realities that make these settings unique. The result is a trusted benchmark that supports informed decision-making, stronger resilience, and confident conversations with regulators, insurers, customers, and stakeholders.
Security Awareness
Build your strongest defence: your people. With Marlink’s Security Awareness programme, designed to turn everyday users into an active line of protection. The majority of incidents begin with human error, from a clicked phishing link to a reused password, and awareness training tackles this risk head-on. We deliver engaging, relevant content tailored to your operations, including realistic phishing simulations that measure and improve resilience over time. Crews, office staff, and leadership each receive material suited to their role, so the message lands and sticks. With ongoing campaigns rather than one-off sessions, we help embed a lasting security culture, reducing risky behaviour and giving your organisation a measurable, human-led layer of defence.

Your Cyber security questions,
answered
Everything you need to know about protection your IT and OT systems.
Marlink Cyber is a managed cyber security services provider specialising in the maritime, offshore energy, oil and gas, and yachting sectors. We protect IT and OT environments through our Unified Cyber Portal integrating endpoint detection, network detection and response, firewall management, remote access, and OT security into a single platform managed by our expert SOC team.
Our primary customers operate in the maritime and offshore energy industries: shipping companies, vessel operators, offshore platforms, port organisations, and superyacht owners. However, Marlink Cyber also serves organisations that do not directly operate in these sectors, we are agnostic.
Yes. While our roots are firmly in maritime and offshore, Marlink Cyber also protects shore-based operations and corporate offices that are connected to, or dependent on, maritime and energy environments. Many of our customers manage a mix of vessel IT, OT systems, and onshore infrastructure we protect the full chain. We reuse the knowledge that we have also on our non-maritime customers thus making sure we are able to deliver the best in class solutions and services.
Our Security Operations Centre operates on a follow-the-sun model, with analysts covering all time zones around the clock. This means your environment is actively monitored 24 hours a day, 7 days a week, 365 days a year not by automated alerts alone, but by experienced human analysts. Every alert is reviewed, triaged, and acted upon. Whether an incident occurs at 3am on a vessel in the Pacific or during a weekend in port, our SOC team is on it.
Yes. Regulatory compliance is a core part of what we do. We have deep experience with frameworks and regulations relevant to our sectors, including the IMO 2021 Maritime Cyber Risk Management guidelines, NIS2, IEC 62443 for OT environments, and sector-specific requirements such as E26/E27 for new-build vesselsn. Our services are designed to provide both the technical controls and the evidence of those controls that auditors and in the maritime sector flag states require. We can help you assess your current posture, close the gaps, and maintain continuous compliance over time.
Maritime, offshore and energy environments are fundamentally different from office IT. Vessels operate in remote locations with satellite connectivity, limited bandwidth, and OT systems that cannot simply be patched or rebooted. Our team understands these constraints we design our solutions around them. We combine deep sector knowledge, a purpose-built Unified Cyber Portal, and a SOC staffed with analysts who know the difference between a vessel's ECDIS and an enterprise workstation.
Onboarding is structured to minimise disruption to operations. We begin with an asset discovery and risk assessment, deploy our monitoring stack (typically EDR, NDR, and firewall management), and integrate your environment into our SOC within a matter of weeks. For new-build vessels or greenfield deployments, we can plan the security architecture from the ground up. Your dedicated onboarding team will guide you through every step.
The easiest way to get started is to contact our team directly through the Marlink website or reach out to your Marlink account manager. We will schedule an introductory call to understand your environment, your risk profile, and your compliance requirements and walk you through a live demonstration of our Unified Cyber Portal tailored to your sector.
