SimSpace, a leader in advanced cyber range technology designed for elite cybersecurity teams, has announced a $39 million funding round consisting of both debt and equity. The investment aims to accelerate the company’s mission of empowering organizations to anticipate and outmaneuver cyber threats across any digital environment.

The new financing round includes participation from BTG Pactual U.S. Private Credit Investments and Communitas Capital, alongside existing investor L2 Point Management, reflecting strong investor confidence in SimSpace’s expanding role in cyber readiness and defense simulation.

Growing Need for Advanced Cyber Ranges

As threat actors increasingly leverage artificial intelligence (AI) to execute more frequent and complex attacks, the demand for realistic cyber training environments—also known as cyber ranges, digital twins, or reinforcement learning (RL) simulations—has reached new heights. Despite escalating threats, many organizations still fail to conduct regular, realistic exercises that measure their defenses under real-world attack conditions.

“The cybersecurity landscape has changed dramatically as adversaries deploy agentic AI to execute more advanced intrusions,” said Peter Lee, CEO of SimSpace. “Annual training events and compliance exercises are no longer enough. Teams must prepare through intelligent, live-fire simulations that replicate actual attack environments to truly validate their readiness.”

SimSpace’s Intelligent Cyber Range Approach

SimSpace’s platform was built on the belief that effective cyber resilience requires continuous rehearsal, validation, and improvement. Its intelligent cyber range replicates an organization’s production network, enabling AI-driven training, technology testing, and performance benchmarking—all within a safe, controlled environment.

Key use cases include:

AI and Agent Validation: Safely train and test AI and machine learning models for threat detection and anomaly recognition using customized datasets.

Live-Fire Attack Exercises: Enable red and blue teams to engage in real-time attack-defense simulations that build tactical readiness under pressure.

Tool Testing and Optimization: Validate the effectiveness of existing security tools and eliminate redundant or underperforming technologies to cut complexity and costs.

Detection Engineering: Enhance detection accuracy by continuously testing and refining threat detection rules, lowering false positives, and improving operational efficiency.

Organizations utilizing SimSpace’s platform report significant gains, including:

  • 30% reduction in cyber operations costs
  • 40% fewer breaches linked to misconfigurations or patching errors
  • 45% better defense against attacks
  • 48% faster breach detection times

Investor Confidence in Next-Gen Cyber Defense

Industry leaders and investors see SimSpace as a pioneer in the convergence of AI, training, and cyber defense innovation.

“SimSpace is operating at the leading edge of modern cyber defense,” said Tom Glocer, Co-Founder and General Partner at Communitas Capital. “Its intelligent simulations mirror the realities of today’s threat landscape, giving organizations the assurance they need to deploy AI securely and effectively.”

Thomas J. Steiglehner, Head of U.S. Private Credit Investments at BTG Pactual Global Alternatives, added: “Our investment strategy focuses on companies transforming industries and addressing urgent global challenges. SimSpace’s cyber range platform offers an unprecedented level of realism and scalability in security training, which is exactly what organizations need in the age of AI-enabled attacks. We’re proud to back their vision for global cyber readiness.”

Building the Future of Cyber Resilience

With this latest infusion of capital, SimSpace is poised to expand its global footprint and continue evolving its cyber range capabilities. The company aims to bridge the gap between compliance-based security practices and real-world readiness—helping organizations move beyond checklists to proactive, data-driven defense validation.

By enabling security teams to train, test, and measure performance against real-world attack scenarios, SimSpace continues to set a new standard for cyber readiness in an AI-driven threat landscape.
