Europe tightens cybersecurity around satellites
European efforts to secure satellites are revealing how deeply space systems are now tied to geopolitical rivalry, digital resilience, and the future of secure communications.
European governments are intensifying their efforts to safeguard satellites from cyberattacks as space becomes an increasingly vital front in modern security and hybrid warfare. Once seen mainly as technical infrastructure, satellites are now treated as strategic assets, carrying critical communications, navigation, and intelligence data that are attractive targets for espionage and disruption.
Concerns intensified after a 2022 cyberattack on the Viasat satellite network coincided with Russia’s invasion of Ukraine, exposing how vulnerable space systems can be during geopolitical crises. Since then, the EU institutions have warned of rising cyber and electronic interference against satellites and ground stations, while several European countries have flagged growing surveillance activities linked to Russia and China.
To reduce risks, Europe is investing in new infrastructure and technologies. One example is a planned satellite ground station in Greenland, backed by the European Space Agency, designed to reduce dependence on the highly sensitive Arctic hub in Svalbard. That location currently handles most European satellite data traffic but relies on a single undersea internet cable, making it a critical point of failure.
At the same time, the EU is advancing with IRIS², a secure satellite communication system designed to provide encrypted connectivity and reduce reliance on foreign providers, such as Starlink. Although the project promises stronger security and European autonomy, it is not expected to be operational for several years.
Experts warn that technology alone is not enough. European governments are still clarifying who is responsible for defending space systems, while the cybersecurity industry struggles to adapt tools designed for Earth-based networks to the unique challenges of space. Better coordination, clearer mandates, and specialised security approaches will be essential as space becomes more contested.
