A solution brief on OT cybersecurity for the teams that run critical infrastructure networks, covering how SimSpace builds a high-fidelity replica of an operational environment for testing that would be unsafe on live plant systems. Sections run from an overview of critical infrastructure cyber range solutions to key capabilities, a “Test Your OT Resilience” section, and results. The technical approach combines hardware-in-the-loop, systemic simulations, and virtual appliances so PLCs, RTUs, HMIs, historians, and supervisory platforms behave as they do in production. Named use cases include validating system-wide baselines, testing new hardware and software before deployment, assessing cyber-kinetic impact, checking interoperability across mixed environments, and tracing cascading failures. The brief is explicit about analyzing how cyber disruptions translate into physical consequence. Download the brief for the results section and the resilience testing detail.
