Secure your operational technology.
Strengthen your resilience.
OT cybersecurity for vessels, rigs, power plants, and every critical operation in between.
Your OT is connected. Now secure it.
Legacy operational technology was never designed to be connected. Today it is. Vessels, port terminals, energy production sites, and industrial plants now share networks with corporate IT, cloud platforms, and remote suppliers. Every new link is a new way in.
Yet ownership is often unclear. In our 2026 Cyber intelligence report, 75% of organisations had no clearly assigned OT security ownership.
The threat is growing. Attackers are using AI to move faster, and regulators and board-level leaders expect answers.
We help you take control. Our OT Security solution is modular, so you address your highest risks first and scale at your pace, all enabled by the Marlink Possibility Platform.
Hear it from our experts
Three perspectives on OT risk: why it matters at board level, where it hides, and how attackers exploit it.
Why OT security is now a board-level priority
Connectivity and AI have changed the OT threat landscape. Nicolas explains why a single compromise can halt operations, and why our customers now treat OT security as a leadership responsibility.
OT blind spots: what you are probably missing
IT incidents that spill into OT. Vendor connections that were never closed. Youri explains how the Marlink Possibility Platform controls third-party access, logs every action, and gives you the evidence auditors and regulators ask for.
How attackers shut down an operation
From a single compromised account to the controllers running your process. Ivan walks through a real attack path, and explains why our red team tests OT under strict rules of engagement while attackers follow none.
IACS UR E27 certified. Built for compliance at sea.
Clear the path to class approval. Our OT Security solution is IACS UR E27 certified, aligned with UR E26, ISA/IEC 62443, NIST CSF, NIS2 and IMO guidelines, and runs on class-verified hardware.
01 - MARITIME
The ship you launched isn't the ship you're sailing.
UR E27-certified OT security, from newbuild to legacy fleet.
Every retrofit, upgrade and new system adds another connected device on board, and every one is a potential way in. Navigation, propulsion, cargo control: when an OT system is compromised, the vessel stops earning. Regulation is catching up. IACS UR E26 and E27 now apply to new builds, IMO requirements already cover cyber risk for vessels in service, and NIS2 raises the bar for operators. Falling behind can mean port delays and higher insurance costs.
Our OT Security solution is UR E27 certified and runs on class-verified hardware, so you start on a compliant foundation, whether you're specifying a newbuild or protecting a vessel already at sea. But compliance is not a one-off exercise. Regulations evolve, systems change, and vessels join your fleet. We help you stay compliant year after year, so you're never rebuilding your evidence from scratch.
It starts with visibility. You can't protect what you can't see, and what's connected today is not what was connected at launch. We map every asset on board, keep that picture current as equipment is added, segment IT from OT, monitor traffic continuously, and control who accesses your systems remotely and for how long. Audit-ready reports mean you arrive at every survey and inspection with the evidence in hand.
The result: fewer blind spots, lasting compliance, and a fleet that keeps operating.
02 - ENERGY, ENTERPRISE, AND GOVERNMENT
Secure the systems that keep critical operations running.
Across energy infrastructure, government services and enterprise operations, OT environments are becoming more connected, more distributed and more exposed to cyberthreats. Industrial control systems, operational assets and supporting IT networks must work together seamlessly to maintain production, service delivery and operational continuity.
We help organisations gain complete visibility across their OT environments, identify vulnerabilities and threats before they impact operations, and securely manage access to critical systems. By combining continuous monitoring, threat detection and robust access controls, we help reduce risk while strengthening operational resilience.
Our approach aligns with recognised industry frameworks, including ISA/IEC 62443 and NIST CSF, helping you protect critical infrastructure, support NIS2 requirements and demonstrate control across increasingly complex operational environments.
Whether you're securing a utility network, government infrastructure, industrial facility or distributed enterprise operation, we provide the visibility and expertise needed to keep critical systems secure, available and resilient.
03 - OTHER INDUSTRIES
Every industry that runs on OT, protected
Production lines, warehouse automation, rail signalling, data centres, building management, and access control systems. If your operations rely on physical equipment controlled by connected systems, you face the same risks: IT incidents spilling into OT, unmanaged vendor access, and limited visibility.
Our modular solution adapts to your environment. Start with what matters most, from asset inventory to managed detection and response, and scale at your pace.
Based on our latest assessment, only 1 in 4 organisations have assigned clear responsibility for the security of their OT systems. Yet these systems keep businesses running, services available, and operations safe.
The question is no longer whether operational technology will be targeted, it's whether your organisation will know about it when it is.
