Cyber threats are evolving.
Remote operations are exposed.
As IT and OT environments become more connected, cyber risk is no longer limited to office networks. Vessels, offshore sites and remote operations now face more complex threats, from credential misuse and phishing to malware, ransomware and exposed systems. Marlink’s SOC helps customers stay ahead of these risks with continuous monitoring, in-house threat intelligence and human-led investigation across IT and OT environments.

Why OT environments need specialist protection
Legacy systems
Network downtime consequences go far beyond inconvenience, leading to lost business.
LIT/OT convergence
Increasing connectivity between operational and business networks creates new attack paths.
Remote access
Third-party and remote access to critical systems introduces persistent exposure.
Safety implications
Compromised OT systems can directly affect operations, physical processes, and personnel safety.
