Beneath the Waves, a New Push for Cable Security

EU funding backs regional cable hubs using AI to detect threats and boost coordination across critical subsea infrastructure

11 Feb 2026

The European Commission has launched a €10mn funding call to support the creation of regional Cable Security Hubs, aimed at strengthening the protection of subsea infrastructure that underpins Europe’s digital and energy networks.

Subsea cables carry more than 95 per cent of global internet traffic and link offshore wind farms to national power grids. Damage to a single cable can disrupt communications, interrupt energy flows and require repairs lasting weeks at significant cost. Recent incidents in heavily trafficked shipping corridors have elevated cable resilience from a technical matter to a strategic concern.

The proposed hubs are designed to improve coordination and situational awareness by combining data from cable monitoring systems with maritime traffic tracking. The Commission’s approach favours regional capability over a single centralised command structure, while encouraging cross-border cooperation under shared European frameworks.

Officials say the aim is to enable faster detection of anomalies, more structured information sharing and improved response planning. The hubs may draw on artificial intelligence-based tools to analyse large volumes of operational data and identify potential threats.

Industry operators already deploy advanced monitoring technologies. Distributed fibre sensing systems can detect temperature shifts or vibrations along cable routes, while maritime tracking platforms monitor vessel movements near sensitive infrastructure. As the hubs take shape, companies may need to align such systems with emerging European standards and collaborative platforms.

Analysts view the funding initiative as part of a broader shift in policy. Subsea infrastructure is increasingly treated as a strategic asset, central to digital sovereignty, economic stability and energy security. By supporting coordinated regional centres, the EU is seeking to formalise cooperation between private operators and public authorities.

Challenges remain. Questions over data governance, confidentiality and interoperability standards will need to be resolved. Automated detection systems must also balance sensitivity with operational practicality to avoid excessive false alarms.

Implementation details are still evolving, and the hubs represent an early stage in what is likely to be a longer process of regulatory and technical development.
