Windward's Q1 2026 report shows behavioral AI now outpaces AIS monitoring for protecting global cable infrastructure

3 Jun 2026

Subsea cable protection is shifting from reactive monitoring to behavioral prediction. Released June 2, Windward's Q1 2026 Undersea Cables Risk Report makes a pointed argument: AIS-based vessel screening can no longer protect infrastructure that carries the majority of the world's internet traffic. Behavioral intelligence, built from fused data sources, is now what actually matters.

The scale of Q1 activity is striking. More than 2,700 events were recorded globally where vessels stayed within cable-proximate zones for over 24 hours. Flag-of-convenience incidents alone accounted for 23.3 percent of all cable-proximate activity, totaling 2,202 cases. Most of those ships cleared standard screening with active transponders, valid flags, and filed paperwork. They still posed credible risk.

Behavioral analysis catches what document checks miss: the shape of conduct over time. Loitering above a cable corridor for 41 days while accumulating four AIS anomalies across 60 days triggers no standard alert. Windward's platform fuses satellite radar, electro-optical imagery, radio frequency data, AIS history, and ownership records into a verified operational picture that conventional screening cannot produce.

Geographically, the Indian Ocean dominated cable-proximate service vessel activity at 63 percent in Q1 2026. Mediterranean routes carried the highest flag-of-convenience penetration at 40.6 percent, while five NATO-adjacent nations, including the UK, Spain, France, Italy, and Denmark, accounted for nearly 80 percent of trawler activity near cable routes. That last figure reflects a resilience challenge driven largely by legitimate commercial fishing, not state actors.

Behavioral intelligence fills a gap that in-cable sensing cannot reach. Where fiber monitoring watches the cable itself, behavioral tools track the vessels around it, identifying risk profiles that build across weeks rather than moments. Record AI-driven subsea investment has raised the stakes on every route. Operators who rely solely on fiber monitoring are now one behavioral gap away from an undetected threat.
