Who Is Really Responsible for Protecting Subsea Cables? in Uncategorized 08/06/2026 A Responsibility Operators Did Not Choose Subsea cables now carry more than 95% of intercontinental data. They underpin the global financial system, the commercial cloud, defense and intelligence communications, and the AI infrastructure being built out at an unprecedented pace. Their importance is recognized, but their protection is not equally structured. Commercial cable operators were built to manage operational risk such as accidental damage, anchor strikes, geological events, and equipment failure. They were not built to defend against state-actor sabotage, nor against the surge in vessel activity that follows when geopolitical events redraw trade routes overnight. Yet that is increasingly the threat profile the industry is being asked to absorb, often without a corresponding shift in who has the authority to respond. Operators are investing heavily in monitoring, threat detection, and behavioral analytics, and the capability to identify a vessel of concern operating near a cable in near real time is increasingly within reach. The constraint sits one step downstream. Preventing an incident may require challenging or removing a vessel, boarding it, or compelling it to identify itself, authorities that sit with naval, coastguard, and law enforcement bodies, rather than with the private company watching the screen. When Detection Is Not Enough This gap is not theoretical. Operators have described repeated cases where vessels near cable routes do not respond to communications, switch off AIS after being contacted, or return to the same area across seasons. The pattern is industry-wide. Windward recorded more than 2,700 events globally where vessels remained near cable routes for over 24 hours during a single quarter, alongside 2,202 flag of convenience activities representing 23.3% of all cable-proximate events, marking a scale of behavior that traditional incident reporting was ne
