Simplify's Take

What believers are saying

  • SimSpace raised $39 million in October 2025, extending runway for expansion.
  • January 2026 Rilian Technologies partnership opens GCC critical infrastructure deals.
  • February 2026 ARIA launch and July 2026 consortium keep SimSpace visible in AI-security.

What critics are saying

  • Dropzone AI, Corelight, Scythe, and Sondera can commoditize simulation benchmarks by 2027.
  • Government-heavy sales expose SimSpace to procurement delays and renewal volatility in 2026.
  • A weak enterprise AI-testing moat leaves SimSpace vulnerable to platform bundling by Palo Alto Networks.

What makes Simspace unique

  • SimSpace’s June 2025 leadership and cyber-command roots fit defense buyers precisely.
  • Its February 2026 Orlando HQ deepens access to Florida’s cyber simulation ecosystem.
  • SimSpace’s range unifies training, testing, and validation across people, tools, and AI.

Reconsider legacy tech and remote-access security in the AI age.

Reconsider legacy tech and remote-access security in the AI age. Corelight, Dropzone AI, Scythe, SimSpace, and Sondera launch AI proving ground. 24th July 2026 Five AI companies are teaming up to boost enterprise trust in AI agents via a new consortium. Secops-focused Dropzone AI said the new AI Proving Ground Consortium (AIPGC) will rigorously train, test, and prove agentic AI defences in production-like environments. Edward Wu, founder and CEO of Dropzone AI, said enterprises need to know they can trust agentic AI. As AI takes on a bigger role, organisations need confidence on how these systems perform in real environments. "The future of the SOC is multiple AI agents working together, alongside human analysts, across investigations, threat hunting, intelligence and response," Wu said. "This consortium can help establish the benchmarks and standards organisations need to confidently adopt AI and accelerate its full operational impact on security." As a result, the first virtual event from the venture between founders Dropzone AI, Corelight, Scythe, SimSpace and Sondera was held mid-June. Peter Lee, CEO of testing platform SimSpace, the lead organiser, said AI weaponisation is a bigger problem than any organisation can handle alone. "That's why we're forming the AIPGC to pool our collective ideas and cyber expertise," Lee confirmed. "AI is transforming cybersecurity. Organisations need a way to rigorously train, test, and validate AI agents together with human cyber operators." AI agents in secops and services. Dropzone AI's agentic secops offering targets managed security services providers (MSSPs). As a result, it has rolled out AI SOC Analyst, enabling autonomous investigation of more alerts and AI Threat Hunter, which runs prebuilt or custom 'hunt' packs for SIEM, EDR, and cloud. In addition, it offers AI Threat Intel Analyst, which analyses and designs responses for the AI Threat Hunter agent. "SimSpace research found that nearly 80% of security leaders report high confidence in their AI defences," the announcement said. "Measured readiness scores can be as low as 30% before repeated simulation exercises." Additionally, many organisations rely on legacy preparation strategies, like tabletop exercises and certification courses, it said.

SimSpace relocates global headquarters to Orlando to advance AI-ready cyber training

SimSpace, a cyber range company, has relocated its global headquarters to Orlando, Florida. The move was announced at the SimSpace Summit and places the company within Florida's integrated cybersecurity ecosystem, closer to key customers, partners and academic institutions including Cyber Florida and PCTE. The new 7,000-square-foot headquarters will support SimSpace's mission to help organisations train, test and validate people, processes, technologies and AI in realistic environments. CEO Peter Lee emphasised the importance of closing the "train-test gap" as cybersecurity enters an AI-driven era. SimSpace's platform serves as an AI proving ground, enabling organisations to test AI-powered tools, train AI models and validate defensive workflows before deployment. The headquarters will function as a hub for customer collaboration and large-scale cyber exercises.

SimSpace launches AI-powered cyber range platform to close training-testing gap

SimSpace has launched an Early Access Program for major upgrades to its AI-powered cyber range platform, designed to bridge what it calls the "Train/Test Gap" in cybersecurity. The platform enables organisations to train and test defensive capabilities across people, processes, technologies and AI in a single production-grade environment. Key enhancements include AI-assisted range design and automation, an intuitive drag-and-drop Range Workbench, Tool Tester for security benchmarking, and improved Team Trainer for live-fire exercises. The platform is built API-first to enable custom integrations and automation at scale. SimSpace positions the upgrades as essential for organisations facing autonomous AI attacks, allowing teams to validate capabilities in realistic conditions before deployment. Current customers can contact account representatives, whilst new customers can express interest through the company's website.

SimSpace Unveils Major Upgrades to its AI-Empowered Cyber Range Platform to Drive the Training and Testing Convergence

SimSpace unveils major upgrades to its ai-empowered Cyber Range Platform to drive the Training and testing convergence. Early Access Program delivers hands-on access to capabilities designed to close the Training/Testing Gap and validate resilience across people, processes, technologies, and AI. BOSTON and ORLANDO, Fla., Feb. 2, 2026 /PRNewswire/ - SimSpace, the realistic, intelligent cyber range for elite cybersecurity organizations, today announced the launch of its Early Access Program for its enhanced SimSpace Cyber Range Platform. This major advancement comes on the heels of SimSpace redefining how organizations unite training and testing to continuously strengthen cyber readiness and resilience in the age of AI. When training and testing are siloed, human and artificial operators are tested to ensure proficiency in isolation from how tools and playbooks actually perform under pressure. SimSpace calls the flaw in this conventional approach the Train / Test Gap. AI-driven threats adapt in real time, and traditional training-only environments can no longer deliver measurable confidence. Research shows: * Training happens in one environment * Organizations value realistic simulation testing, but implementation is scattered at best * AI is a priority, but security teams can't prove its efficacy SimSpace tackles this by uniting training and testing in a single production-grade cyber range where elite cyber individuals, teams, and entire organizations can safely and rapidly train, test, and validate their offensive and defensive capabilities across people, processes, and technologies. Organizations can only claim readiness when they repeatedly train and test in environments that reflect the complexity of real operations, which include cloud infrastructure, production tools, hardware, human behavior, and now adaptive AI. "Autonomous AI attacks are pushing the asymmetry between offense and defense to a breaking point, and defenders can't afford to rely on isolated training or theoretical testing anymore," said Clint Sand, Chief Product and Engineering Officer of SimSpace. "What's required now is a full lifecycle approach. Training, testing, and validating in realistic conditions that reflect how systems actually operate. Organizations need to adopt AI rapidly, but they also need to manage the operational risk of deploying unproven autonomous agents. With Early Access, SimSpace provides a responsive, adversarial environment where teams can validate people, processes, technologies, and AI together. Before those capabilities are trusted in the real world." AI is accelerating the convergence of training and testing. The way you train AI is by testing it; the same is now true for cyber operators, workflows, and full-stack defenses. SimSpace designed its platform to enable this convergence as a strategic advantage for customers. SimSpace combines learning, testing, validation, and performance measurements into a single realism-first environment. Key highlights of major upgrades to the platform unveiled include:
