Rebel Space Technologies

AI-powered cybersecurity for space systems

Overview

Rebel Space Technologies builds AI-powered cybersecurity software for space systems. Its Rebel Space Platform offers an end-to-end solution that detects, identifies, and mitigates wireless risks for both space assets and ground infrastructure. It delivers real-time insights into the wireless environment and threat landscape, enabling rapid response to RF and cyber threats, with in-depth reporting and risk notifications to help anticipate and mitigate vulnerabilities. The company differentiates itself by combining artificial intelligence, cybersecurity, and radio-frequency sensing in a space-focused platform designed to monitor and protect space systems from cyber and RF threats, both in orbit and on the ground. Its goal is to help space operators—whether private companies or government agencies—achieve cyber-resilient missions by licensing software and, potentially, providing threat monitoring and response services.
