SimSpace raises $39 million in new funding from private credit and equity investors.
The platform provides realistic cyber ranges for AI-driven training and live-fire exercises.
It addresses the growing threat of adversaries weaponizing agentic AI for attacks.
Use cases include AI model validation, tool testing, and detection engineering.
The company reports clients see a 48% improvement in time to detect a breach.
Funding will support global expansion and new use case development.
Bridging the Cyber Readiness Gap
The core problem SimSpace addresses is the inadequacy of traditional cybersecurity training, such as annual exercises, in an era where AI-powered adversaries attack with increasing frequency and sophistication. A SimSpace cyber range creates a realistic, intelligent replica of a customer's production environment. This allows for continuous, AI-driven training and validation, moving beyond individual compliance to real-world team and technology evaluations under high-stress, realistic conditions.
Key Applications of the Cyber Range Platform
The platform serves several critical functions for modern security teams. It enables AI model training and agent validation, allowing organizations to develop and test their own AI agents for threat detection in a secure, customized environment. It also facilitates live-fire exercises where red and blue teams can practice their skills against realistic attack simulations. Furthermore, organizations can use it to test and optimize security tools and enhance detection engineering by refining rules to reduce false positives.
Proven Impact and Strategic Vision
The value proposition is backed by measurable outcomes. SimSpace reports that its clients achieve a 30% savings in cyber operational costs, a 40% reduction in configuration-related breaches, and a 48% improvement in the time to detect a breach. This focus on validation under real-world conditions is what attracted investor confidence. "I believe the company will redefine how organizations prepare for adversaries," said Tom Glocer, Co-Founder and General Partner at Communitas Capital.
Founded by innovators from US Cyber Command and MIT Lincoln Laboratory, SimSpace is positioned at the frontier of cyber defense innovation. This new funding will enable the company to expand globally and better serve its base of government, university, and Fortune 100 clients, ensuring they can deploy agentic AI safely and effectively against evolving threats.
For elite cybersecurity teams under siege in an AI-fueled threat landscape, SimSpace is the realistic, intelligent cyber range that strengthens teams, technologies, and processes to outsmart adversaries before the fight begins.
