What SimSpace does
SimSpace is a US-based cybersecurity software company founded in 2015 by veterans of US Cyber Command and MIT Lincoln Laboratory to build high-fidelity, military-grade cyber ranges for elite military, intelligence, and enterprise security teams. Its core product is the SimSpace Cyber Range Platform, a cloud-based, AI-empowered simulation environment that mirrors production IT, OT, and cloud systems with realistic applications, data, users, and adversaries. The platform is organized under the AI Proving Grounds umbrella and comprises three modules — Tool Tester for validating security tools and AI agents in isolated environments, Team Trainer for joint human-AI live-fire exercises, and Range Workbench for designing, versioning, and managing ranges via visual canvas or GitOps-compatible YAML. The proprietary ARIA agent, launched in February 2026, translates natural language into production-grade cyber simulations.
SimSpace generates revenue primarily through enterprise platform subscriptions to the Cyber Range Platform (sold as multi-year contracts via direct sales and a global partner ecosystem led by Booz Allen Hamilton, Carahsoft, and Rilian Technologies), supplemented by professional services including Cyber Drills as a Service and SOC assessments. The customer base spans at least eight verticals — US Federal & Military (the primary segment), State & Local Government, International Ministries of Defense, Critical Infrastructure, Financial Services, Healthcare, Higher Education, and Insurance — with marquee deployments across the UAE, Croatia, Slovenia, and multiple US federal agencies. Pricing is quote-based with no public list, and procurement is typically supported through channel partners for federal, state, and international markets.
As of early 2026, the company employs between 101 and 250 staff across offices in Orlando (relocated global HQ), Boston (legacy office), and Dubai, led by CEO Peter Lee alongside co-founders Lee Rossey (CTO) and William "Hutch" Hutchison. The company has raised approximately $84 million-plus across recent debt and equity rounds, holds Forrester Wave Leader status for Cybersecurity Skills and Training Platforms, and was recognized with the 2024 CyberSecurity Breakthrough Security Training Innovation Award.

SimSpace product offering
Product offeringCore offering
SimSpace provides a cloud-based, AI-empowered Cyber Range Platform that creates high-fidelity digital replicas of enterprise IT, OT, and cloud systems to enable cybersecurity training, tool and AI agent validation, and continuous mission rehearsal. The platform is delivered under the AI Proving Grounds umbrella and includes the Tool Tester, Team Trainer, Range Workbench, and ARIA (Artificial Range Intelligence Agent) capabilities for customers in U.S. federal/military, international defense, critical infrastructure, financial services, healthcare, higher education, insurance, and state/local government sectors.
Product overview
SimSpace offers the SimSpace Cyber Range Platform, a realistic, intelligent cyber simulation platform that converges training and testing for elite cybersecurity teams. The platform is organized under the AI Proving Grounds, an umbrella offering that enables organizations to build, test, and operationalize AI agents together with human operators. Within the AI Proving Grounds, three primary modules address different needs: Tool Tester validates AI agents and security tools in realistic environments before production deployment; Team Trainer trains human operators and AI agents together in live-fire exercises with mission-driven templates and repeatable run plans; and Range Workbench designs, versions, and manages production-grade cyber ranges using a drag-and-drop canvas or YAML blueprints compatible with GitOps workflows. ARIA (Artificial Range Intelligence Agent) is an AI-powered capability launched in February 2026 that translates natural language into detailed cyber simulations, lowering the barrier to range creation. The platform serves industries including critical infrastructure, financial services, healthcare, higher education, insurance, international governments, state and local agencies, and U.S. federal and military organizations.

SimSpace competitors and assessment
Company assessmentDirect peers
- Immersive Labs: Immersive Labs is a direct peer operating a cyber skills, training, and readiness platform for enterprise and government security teams. It competes head-to-head with SimSpace in Gartner/Forrester evaluations of cybersecurity skills and training platforms and serves overlapping buyers including CISOs and SOC leadership.
- Cyberbit: Cyberbit provides a commercial cyber range platform for security training, simulation, and SOC team readiness, targeting enterprises and government/defense customers. Its product breadth (range, simulation, SOC automation) and customer overlap make it a direct comparable to SimSpace's Cyber Range Platform.
- RangeForce: RangeForce delivers a cloud-based cyber skills training and readiness platform with hands-on labs and adversary emulation for enterprise security teams. It is closely comparable to SimSpace on training methodology, SaaS delivery model, and target buyer (CISO/SOC leadership in regulated industries).
- Cloud Range: Cloud Range is a direct competitor offering live-fire cyber range exercises and SOC team training delivered as a service to enterprise and government clients. Its service-led range model mirrors SimSpace's Cyber Drills as a Service and serves similar Fortune 500 and federal buyers.
- Circadence: Circadence provides persistent, gamified cyber ranges and learning platforms for enterprise and government cybersecurity teams, including K-12 and higher education. It competes with SimSpace in the same cyber range category, particularly in U.S. federal and education procurement channels.
- Hack The Box: Hack The Box operates a cybersecurity upskilling and talent assessment platform combining CTF-style content with enterprise training. It is comparable to SimSpace on training category and buyer (security teams and learners), though it skews more toward individual/community learners and SMBs.
Emerging players
- TryHackMe: TryHackMe is an emerging player in guided cybersecurity training rooms and learning paths, popular with students, SOC analysts, and individual practitioners. While smaller and more consumer/SMB focused than SimSpace, it is increasingly moving upmarket and overlaps on skills-development use cases.
Broad incumbents
- Microsoft (Security / Defender): Microsoft is a broad incumbent with a wide cybersecurity portfolio (Defender, Sentinel, security training content) that increasingly bundles training and validation capabilities. It does not specialize in cyber ranges but competes for the same enterprise security budget and could pressure SimSpace via bundling.
- Palo Alto Networks: Palo Alto Networks is a broad incumbent in enterprise security platforms with growing investment in security operations, AI, and training-adjacent offerings through Unit 42 and Prisma. Its scale and platform bundling could compress standalone range/training vendors like SimSpace.
- ManTech (Cyber Range & Federal Services): ManTech delivers federal cybersecurity services including cyber range operations and training for defense and intelligence customers. It is a broad incumbent competing for similar U.S. Federal contracts and often appearing alongside or against SimSpace in defense procurement vehicles.
