Tell Us About SimSpace
SimSpace was founded on a simple yet increasingly urgent insight: cybersecurity suffers from a train–test gap. Training defenders is essential, but without rigorous testing of tools, processes, configurations, and now AI-driven decision logic, organizations are operating with blind spots. SimSpace closes that gap.
As the realistic, intelligent cyber range built by former US Cyber Command and MIT Lincoln Laboratory innovators, SimSpace enables continuous mission rehearsal and objective performance validation in environments that mirror real-world operational complexity. From universities educating the next generation of cyber talent to Fortune 500 and government agencies testing AI agents, validating tech stacks, and optimizing SOC workflows, SimSpace helps organizations outsmart adversaries before the fight begins.
SimSpace delivers readiness you can measure, outcomes you can trust, and resilience you can prove, because in modern cybersecurity, training alone is no longer enough.
Why Do You Think the Cybersecurity Sector Needed An Innovation Like This?
Cybersecurity has reached a breaking point. AI-driven adversaries are moving faster than traditional training cycles can keep pace, and point-in-time assessments cannot keep up. For years, cyber ranges focused primarily on human training. Valuable, but incomplete. What organizations lacked was a way to train and test people, processes, technologies, and now, AI itself in a single unified environment.
SimSpace was built specifically for this moment. Modern cyber readiness requires continuous mission rehearsal, realism at production scale, and validation under adversarial pressure. Traditional ranges stop at drills; SimSpace closes that “train–test gap,” enabling objective measurement, configuration verification, and resilience scoring across teams, tools, and AI agents.
This convergence is now essential. The way you strengthen AI models is by testing them; the same principle applies to defenders and infrastructure. The sector needs a platform that builds trusted readiness because what gets trained is proven, and what gets tested is trusted.
How Has SimSpace Grown In 2025?
2025 was a year of expansion, acceleration, and customer-driven innovation for SimSpace.
We advanced every pillar of the platform (Train, Test, and Validate) to meet the needs of elite organizations adopting AI faster than ever:
- Next-generation range management to deliver stable, scalable, realistic environments for new use cases.
- AI integration and AI training capabilities, enabling customers to train and test AI decision logic, validate agentic workflows, and optimize autonomous security operations.
- We also saw increasing global adoption across defense, government, financial services, critical infrastructure, and cloud-first enterprises, all seeking a realistic, intelligent range that reflects how they truly operate.
- Raised $39M in new funding to further our mission.
Underlying all this growth is the same mission that has guided SimSpace since 2015: defend the free world, outsmart any threat in any terrain, and help elite teams fight smart.
What Does SimSpace Have In Store for 2026?
In 2026, SimSpace will scale the future of cyber readiness by deepening the convergence of training, testing, and AI validation and delivering it to organizations that need measurable certainty.
Key product areas of focus include:
- AI-Native Readiness: We will expand capabilities that allow organizations to safely train, test, and pressure-test AI agents and autonomous workflows in realistic adversarial environments. This includes next-generation analytics and scoring engines that quantify the performance of teams, tools, and AI together.
- Faster, Realistic Range Creation: Building on our current platform, 2026 will push automation even further, enabling cyber operators to quickly generate complex, realistic environments.
Sector-Specific Terrain Expansion: deeper content and tailored ranges for OT/ICS, healthcare, cloud-native architectures, and cross-border operational environments, reflecting the increasing demand for mission-aligned realism. - Unified Readiness Intelligence: We will continue advancing unified resilience scoring and reporting so CISOs can quantify readiness with the same rigor they apply to financial or operational metrics.
Key business areas of focus include:
- Hosting our first-ever SimSpace Summit, the global Cyber Range leadership conference of the year. Key speakers include General (retired) Stanley McChrystal, Former Commander of Joint Special Operations Command, Cyber Florida, Rillian Technologies, Google Security, and Shigeru Kitamura-san, Former Secretary General of the National Security Secretariat and Former Director of Cabinet Intelligence
- Partnerships with companies, especially in the Middle East and UK, to further expand awareness and usage of our Cyber Range platform.
The goal: trusted, repeatable measurements of how well people, processes, technologies, and AI can withstand real attack conditions.
