The CybergymIEC Cyber Training Arena is a physical and virtual cybersecurity training environment that simulates real-world cyberattacks. Unlike virtual cyber ranges, the Cyber Arena conducts live attack simulations on participants' actual physical machines, replicating threats that an organization may realistically face. The platform is available in three deployment formats: - CyberGround: A full-scale, on-premises training arena for organization-wide training. - CyberPod: A compact arena that connects remotely to CybergymIEC's global arena network. - Virtual Cloud Arena: An online platform offering multi-user access to training programs tailored to different skill levels and roles. A core differentiator is its specialization in Operational Technology (OT) and IoT environments. The arenas replicate OT/IoT infrastructure — including power generation and distribution hardware such as turbines — allowing trainees to practice defending against attacks on actual industrial equipment. Training sessions are facilitated and debriefed by a Red Team, which runs attack scenarios and provides feedback on trainee performance from an attacker's perspective. The platform is designed to train personnel to detect, contain, and mitigate cybersecurity threats through hands-on exercises.
