Satellite Security in a changing threat landscape

Across Europe, space and security organisations are observing a clear rise in advanced and potentially intrusive satellite activities. Inspector‑type satellites have been detected manoeuvring unusually close to key communication satellites, raising concerns about attempts to monitor or interfere with operational systems that underpin critical services.
Several satellites in geostationary orbit have experienced unexpected close approaches, highlighting long‑standing vulnerabilities in legacy systems that were never designed with today’s threat environment in mind. At the same time, investigations on the ground show attempts to access satellite‑related data through specialised equipment — a reminder that risks extend across the entire space ecosystem, including rapidly growing broadband and Earth‑observation systems in Low Earth Orbit.
A common theme across all reporting is that these threats are not hypothetical. They represent a real and evolving challenge for satellite operators, governments, and industries that rely on stable, trusted space‑based infrastructure.
As reliance on satellites continues to grow, so does the importance of robust protections. Modern systems must be equipped to authenticate commands, safeguard control channels, and maintain the integrity of critical communications — regardless of orbit or platform.
This is why solutions such as EIDEL Secure Satellite Link (SSL) have been developed: to strengthen the resilience of satellite operations and help ensure that Europe’s space infrastructure remains protected in an increasingly complex and competitive environment.
