Submarine Cable Security: Global Vulnerabilities and EU Response

• •Submarine cables are vital for global internet traffic, with 99% reliance on them.
• •The EU has committed €347 million to enhance submarine cable security and repair capabilities.
• •Multiple simultaneous disruptions could exceed current repair capacities, especially in wartime.

On November 5, 2026, a report highlighted the strategic vulnerabilities of global submarine cable infrastructure, which carries 99% of intercontinental internet traffic. The report noted that multiple disruptions could overwhelm international repair capacities, especially during military conflicts. The European Commission has allocated €347 million for submarine cable security, including a €20 million call for adaptable repair modules. This initiative aims to enhance emergency response capabilities across the EU, particularly in the Baltic Sea, Mediterranean, and Atlantic regions. The European Health and Digital Executive Agency has launched a second call for proposals to develop emergency repair modules for submarine cables. The situation underscores the critical need for resilient digital infrastructure amid rising geopolitical tensions and potential threats to undersea cables.
