Cybexer Cyber Ranges for Smart Cities is a cyber range training platform designed specifically for smart city environments. The platform enables organizations to safely test and manage critical IT systems in a controlled environment without disrupting live operations. The solution provides a simulated environment where smart city operators can practice incident response, test new technologies, and validate system configurations before deployment. This allows cities to accelerate innovation while minimizing the risk of service disruptions to citizens. The platform is used by government organizations, defense agencies, educational institutions, and critical infrastructure operators. Clients include NATO agencies, European government bodies, defense forces, and various public sector organizations. The cyber range environment supports testing of interconnected smart city systems including IoT devices, network infrastructure, and critical services. Organizations can use the platform to train technical teams, validate security controls, and assess the resilience of their smart city infrastructure against cyber threats. The solution enables cities to maintain operational continuity while implementing new digital services and technologies. By providing a safe testing ground, the platform helps reduce the risk associated with deploying complex IT systems in production environments.
