This solution brief introduces the SimSpace federal cyber range for defense and civilian agencies that must prove mission systems hold up against nation-state attack. It opens on the constraint that drives the whole document: mission systems, defensive tools and operational workflows have to perform under pressure, yet cannot be fully validated in live environments without risk to national security. Three capability sections follow. Continuous Mission Rehearsal and Team Training covers live-fire exercises that put operators, analysts and leadership through a simulated cyber defense exercise. Test Systems Against Nation-State Threats describes simulating advanced persistent threats and multi-domain attacks across IT, OT and mission systems including C4ISR and NC3. Validate Controls and Prove Readiness explains how control effectiveness is demonstrated against NIST, FISMA, CMMC and DoD frameworks using automated scoring. The brief closes on four claimed outcomes, among them measured mission readiness, greater trust in AI-assisted workflows and audit-ready compliance evidence. Download the brief to see how each capability maps to your accreditation requirements.
