Prysmian Group: A Strategic Asset for Europe’s Energy and Data Security

Prysmian Group stands as the invisible backbone of Europe’s energy and information networks. Headquartered in Italy, this century-old company has quietly become a linchpin for critical infrastructure, from undersea power links connecting national grids to fiber-optic cables carrying Europe’s data.
