NATO Review: Reinforcing resilience: NATO’s role in enhanced security for critical undersea infrastructure

Undersea infrastructure is vital in a global economy powered by data. 99% of the world’s data is transmitted through a global network of subsea cables. An estimated USD 10 trillion in financial transactions alone traverses these vast cable networks each day. As well as data cables, critical undersea infrastructure also includes electricity connectors and pipelines supplying oil and gas. As great power tensions escalate, undersea infrastructure serving the Euro-Atlantic community has emerged as an attractive target for hybrid interference, meaning that the security of this infrastructure should be a NATO priority.
