Recent coverage underscores the UK’s heightened focus on the critical role of subsea cables, which carry over 95% of intercontinental data, supporting everything from business operations to national security. Unlike satellites, these 1.3 million kilometres of underwater cables are integral to digital infrastructure, with any break posing swift, widespread impact.
Government strategies now emphasise not only cyber resilience but also physical security, including advanced monitoring and collaboration with defence entities. For IT leaders, resilience plans must account for potential cable incidents—through multi-path routing, regular scenario exercises, and attention to less-visible risks. As government concern grows, the message is clear: rigorous digital defence relies on protecting what’s beneath the waves, not just online.
