Talk to a Cyber Range Expert

CybExer is the key technology partner of the European Space Agency in building the Space Cyber Range

In 2025, ESA selected CybExer as the key technology partner for the Space Cyber Range (SCR), a groundbreaking initiative under the ESA ARTES 4.0 (4S) programme.

The SCR is designed to be a safe, scalable, and collaborative environment where Europe’s satellite operators, integrators, and cybersecurity experts can validate space systems, test resilience, and train teams against real-world threats.

What the Space Cyber Range Provides

Realistic Training and Live-Fire Exercises: Organizations can run cyber defense exercises in environments that mirror real space and ground systems. Teams gain hands-on experience in responding to advanced threats without risking live missions.

Validation and Certification Readiness: Systems and processes can be tested against ESA-grade security requirements. This supports operators in preparing for certification and demonstrating compliance with regulatory standards.

System and Communication Testing: The range makes it possible to assess the resilience of end-to-end space architectures. Vulnerabilities in communication links and system integration can be identified before launch.

Knowledge Sharing and Custom Scenarios: Users have access to a collaborative environment that includes reusable training content and mission-specific simulations. Complex challenges such as collision avoidance or multi-actor operations can be modeled and tested.

Secure, Scalable, Endlessly Customisable

Build your cyber resilience with flexible on-prem and subscription-based cyber ranges – delivered by a team with unrivalled experience designing custom solutions for high-tech clients.

Be Mission-ready

Improve the cyber resilience of your satellites, and the ground-based systems they rely on.

Our cyber ranges for the space industry provide a controlled environment where you can test, experiment, and refine to ensure you’re ready for launch.

The range reveals vulnerabilities in both space and ground segments, giving operators a clear understanding of evolving threats before launch.
Testing in a virtual environment reduces expenses and accelerates development, allowing issues to be resolved early without impacting missions.
Teams and partners can train together in realistic scenarios, improving coordination and readiness across the entire ecosystem
The range prepares organizations for emerging regulatory and certification requirements, ensuring systems meet the standards expected in the space sector.

Enhancing Satellite Security with the University of Tartu

The University of Tartu and CybExer joined forces on a multi-year project to revolutionise cybersecurity in the space industry.

Using our cyber range solutions, the project team created a digital twin of the ESTCube-2 satellite control system. The sophisticated virtual replica enables the team to test and develop new cybersecurity measures safely.
