What is Simspace?
SimSpace operates at the intersection of cybersecurity, enterprise training, and infrastructure simulation. The company provides sophisticated cyber ranges—virtualized, high-fidelity replicas of an organization's actual technology stack. These environments allow security teams to conduct live-fire exercises, emulate complex attacker behaviors, and refine incident response protocols without risking production systems. Founded by veterans of national cyber defense and academic research, the Boston-based firm addresses the critical gap between theoretical security training and the realities of modern, large-scale cyber warfare. By enabling continuous, realistic testing, SimSpace empowers organizations to move from reactive security postures to proactive, battle-tested defense strategies.
