SimSpace is a private cybersecurity simulation software company focused on realistic cyber range technology for modern cyber defense. Founded in 2015, it helps organizations rehearse attacks, train operators, test security tooling, and evaluate AI agents inside high-fidelity replicas of their own environments rather than generic labs.
SimSpace positions its platform as the AI Proving Grounds: a unified environment where human defenders and AI systems can be trained, tested, and validated together before production deployment. Its offerings are built to improve measurable readiness across enterprise, government, and mission-critical environments, with use cases spanning cyber training, tool optimization, compliance validation, disaster recovery, and operational resilience.
Offerings, Capabilities, and Integrations
SimSpace delivers realistic cyber simulation across the full environment stack, including network and operating system architecture, apps and security tools, data, identities, endpoints, user activity, network traffic, and attack scenarios. Its platform is designed to mirror IT, cloud, OT, IoT, and ICS environments, and it can incorporate real hardware for more authentic simulation when needed.
The company’s capabilities center on live-fire attack emulation, realistic user and adversary behavior, AI-assisted range generation, synthetic data generation for AI training, and scoring and reporting that quantify readiness over time. SimSpace also supports infrastructure-as-code workflows and is built API-first, giving customers and partners secure programmatic access for custom integrations, automation, advanced workflows, and data extensibility.
Products and Services
- AI Proving Grounds: SimSpace’s flagship environment for training human operators and testing AI agents together in realistic replicas of production environments. It is designed to generate training data, evaluate agentic performance, identify failure modes, and build trust before deployment.
- SimSpace Cyber Range Platform: The core cyber simulation platform that supports live-fire training, testing, and validation across people, processes, tools, and AI. It models production-like enterprise and mission environments to help organizations measure resilience and improve readiness.
- ARIA: An AI-assisted range design and automation capability that translates simple language into structured changes across networks, users, attack paths, and defensive controls. It supports reusable components, orchestration, and infrastructure-as-code workflows for faster range creation and modification.
- Range Workbench: A range design and management product with a drag-and-drop canvas, human-readable YAML editing, versioning, rollback, and audit support. It helps teams build and maintain production-grade cyber ranges with repeatability and governance.
- Tool Tester: A realistic, isolated test environment for evaluating security tools, AI agents, rules, and configurations before production rollout. It includes scenario-driven validation workflows and scoring analytics for detection engineering and tool benchmarking.
- Team Trainer: A live-fire exercise product for planning, running, and repeating mission-driven cyber exercises. It provides templates, inject control, reusable run plans, and scheduling to make team training more repeatable and measurable.
- Validate: SimSpace’s validation offering for proving that controls, processes, and agentic workflows perform under realistic conditions. It covers use cases such as verifying agentic workflows, proving disaster recovery readiness, and demonstrating compliance with audit-ready evidence.
Target Customers
SimSpace targets organizations with mature or high-consequence security operations that need production-realistic rehearsal and evidence-based validation. Typical buyers and users include SOC teams, incident responders, detection engineers, security engineering teams, cyber defense leaders, and organizations introducing AI agents or AI-assisted workflows into security operations.
Its market spans commercial enterprises and public sector organizations, with clear focus on financial services, critical infrastructure, healthcare, insurance, and higher education. SimSpace also serves state and local government, U.S. federal and military organizations, allied governments, and research universities that require mission assurance, compliance proof, operational continuity, or OT and IT resilience under real-world pressure.
