Denmark is intensifying its efforts to protect critical infrastructure from hybrid threats and cyberattacks. Initially, focus was placed on district heating plants, which began implementing stringent security measures following assessments that Russian-aligned hackers were conducting destructive attacks. Experts noted that even a brief breach could potentially shut down these essential services.

This defensive posture has expanded into broader national strategies. The country is addressing heightened digital risks through the Cyber Alliance, which facilitates cooperation across interconnected sectors including energy, telecommunications, finance, and transport. This initiative emphasizes that cross-sector coordination and shared situational awareness are necessary to mitigate geopolitical and digital risks to society.
