EU Space ISAC

In 2022, EU leaders identified space as a strategic domain in the Strategic Compass and called for an EU Space Strategy for Security and Defence. Building on this political momentum, the Commission and the High Representative have developed the first-ever EU Space Strategy for Security and Defence. 

In the current geopolitical context of increasing power competition and intensification of threats, the EU is taking action to protect its space assets, defend its interests, deter hostile activities in space and strengthen its strategic posture and autonomy.

In the light of this, the European Commission and EUSPA are spearheading the formation of the EU Space Information Sharing Centre (ISAC). This network-based information-sharing platform promotes collaboration, awareness and best practices among private entities to ensure the safety of our space systems and the networks they rely on.
