Digital infrastructure is now critical national infrastructure. Subsea cables, terrestrial networks, data centres and the power systems that underpin them shape economies, and they face growing pressure from geopolitical tension, physical interference and increasingly sophisticated threats. This summit brings together the operators who run this infrastructure with governments, regulators, security stakeholders and insurers to align on the threat landscape and coordinate practical responses. This is a candid, application-only environment for C-level leaders ready to act.
