SimSpace’s mission is to revolutionize organizational security through realistic emulations and to provide an automated, cost-effective evaluation method for calculating cyber risks. SimSpace aims to prepare and empower chief information security officers and practitioners to better defend against advanced adversaries by modeling, quantifying, and ultimately enhancing their cybersecurity posture. The company’s goal is to help organizations understand cyber attacks before they occur by providing emulations and training so they can test, train, and drill their defenders, tools, and processes in a model of their environment. This allows organizations to train as they would fight.
SimSpace is recognized as a global leader in military-grade cyber ranges. The company is known for its high-fidelity cyber ranges and training content, combined with unique user and adversary emulation techniques. SimSpace serves sophisticated enterprises, governments, and critical national infrastructure organizations. Its platform is used by Fortune 2000 companies, major financial institutions, and U.S. government and military organizations. Industry analysts like Gartner and Forrester recognize SimSpace as a key player and leader in cybersecurity readiness and training simulation.
Offerings, Capabilities, and Integrations
SimSpace provides a comprehensive cybersecurity risk management platform centered around its military-grade cyber range technology. This platform allows organizations to create high-fidelity, realistic simulations of their own IT and operational technology (OT) environments, including network infrastructure and security tools. Within these simulated environments, SimSpace enables “live-fire” team training exercises, individual and team assessments, security technology evaluations, and mission rehearsals. SimSpace’s core capability lies in its ability to emulate real-world cyber-attacks, including advanced persistent threats (APTs), zero-day exploits, ransomware, and DDoS attacks, along with realistic user behavior through automated “digital workers”. This allows security teams (SOC, Red, Blue, Purple teams), security engineers, and incident response teams to practice and validate their skills, processes, and technologies in a safe, controlled setting without risking production systems.
A key competitive advantage for SimSpace is the realism and high fidelity of its cyber ranges, originally developed for U.S. Cyber Command. The platform’s ability to create digital replicas of an organization’s entire technology stack and generate authentic network traffic sets it apart. SimSpace offers customization and automation, allowing for tailored training and assessment plans, and can rapidly stand up secure, scalable environments in virtual, physical, or blended deployments. The platform integrates with a wide array of security products from vendors like Splunk, CrowdStrike, Microsoft, and Mandiant, allowing organizations to test and optimize their existing security stack. These capabilities provide quantitative, actionable insights into an organization’s cyber readiness and help improve security posture, reduce cyber operational costs, and ensure compliance. This focus on realistic, hands-on experience and measurable outcomes positions SimSpace as a leader in the cybersecurity training and risk management market.
