Undersea cable risks
Windward's latest Undersea Cables Risk Report highlights significant concentrations of vessel activity around critical subsea routes. Subsea cables connect offshore wind farms, carry telecommunications and support energy infrastructure. Damage or disruption can have cascading effects across energy, communications and financial systems.

Cyber hygiene for marine suppliers
Small marine suppliers often connect into larger operators through email, portals, vessel schedules, documents and subcontracting chains. The National Cyber Security Centre provides guidance relevant to businesses of all sizes. Cyber hygiene, access control, backup discipline and careful handling of operational information matter even for small businesses.
