EU Space ISAC banner

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.

Why Participate?

  • Stay Informed: engage in information sharing about security-related information, incidents*, cyber trends, vulnerabilities, and threats.
  • Stay Ahead: benefit from early warning systems, getting timely alerts on security threats, enabling swift responses.
  • Develop Together: enhance collective cybersecurity resilience through knowledge sharing, best practices, and expertise pooling.
  • Access Expertise: engage with cybersecurity experts, public sector agencies, and other stakeholders for guidance and support.
  • Network: build connections with industry peers and public partners, fostering collaborative solutions to common challenges.
