SimSpace Corporation, founded in 2015 by alumni of U.S. Cyber Command and MIT's Lincoln Laboratory, builds cyber range infrastructure. The threat model: sophisticated, persistent adversaries targeting government agencies, critical infrastructure, and large enterprises. The problem is that conventional training doesn't prepare defenders for real-world complexity - tools behave differently under pressure, AI agents need stress-testing, and postures degrade against novel tactics.
The company's Cyber Range Platform runs hyper-realistic environments where security teams conduct continuous mission rehearsal. Think of it as a proving ground where red and blue teams can safely fail, iterate on playbooks, and validate that defensive tooling actually works before an incident forces the question. The platform is designed for testing AI-driven security agents alongside human operators, a domain that's becoming non-negotiable as automation expands the attack surface.
Gartner and Forrester have both recognized the platform as among the most advanced in its category. SimSpace operates out of the United States, serving organizations across federal, defense, critical infrastructure, and enterprise verticals. The technical stack spans simulation, AI, and cybersecurity domains - engineers here are building at the intersection of realistic adversarial modeling and scalable training infrastructure.
