Overview

SimSpace is a cyber range company headquartered in Boston, Massachusetts, and founded in 2015 by veterans of United States Cyber Command. The company builds high fidelity replicas of customer networks where security teams rehearse attacks, test detection tooling, and measure their own readiness under realistic conditions. It sells to banks, critical infrastructure operators, government agencies, and military units that need to validate defences without touching production systems.
