Fidelitas Defense is a dual-use, AI-native Software-as-a-Service (SaaS) company delivering Systems Assurance, Supply Chain, Foreign Ownership, Control, or Influence (FOCI), and Regulatory Risk Management for safety and mission-critical AI systems. Born out of the Massachusetts Institute of Technology (MIT), the company is founded by former U.S. Intelligence Community professionals and military veterans.
We deliver HORIZON-X — a browser-accessible, dual-use, AI-native SaaS platform purpose-built to safeguard Physical AI, Autonomous Vehicles and Robotics (PAI-AVR) systems against Cyber, Supply Chain, and Systems Assurance risk. HORIZON-X enables Enterprise, Government, and Regulated-Industry customers to identify, assess, and manage Systems Assurance gaps, Supply Chain risk, FOCI exposure, and Regulatory Compliance across complex cyber-physical environments.
Our Solutions support organizations across Defense (U.S., FVEY, NATO, Japan), Autonomous Vehicles (Air, Land, and Maritime), MedTech, and Defense/Dual-Use Technology Investment (VC, Private Equity, M&A) — enabling secure operations as AI systems increasingly intersect with human safety, mission-critical operations, and national security.
Boards, C-Suite executives, Supply Chain, Product Development, Security Operations (SOC), Acquisition, Investor, and Regulatory risk teams face a rapidly evolving threat landscape. Physical AI, Autonomous Vehicles, and Robotics (PAI-AVR) are advancing faster than traditional cybersecurity tools, risk practices, and regulatory frameworks, increasing exposure to cyberattacks, insider threats, and supply chain compromise — putting compliance, operations, product development, and organizational continuity at risk.
Fidelitas Defense combines deep domain expertise with proprietary PAI-AVR Technology & Regulatory Diligence frameworks and AI-native workflows to help organizations assess and strengthen Systems Assurance, Supply Chain Risk, Foreign Ownership, Control, or Influence (FOCI), and Regulatory Risk Management. Our Solutions also support Technology and Regulatory Due Diligence for Venture Capital, Private Equity, and M&A investment decisions, enabling investors and acquirers to uncover hidden risks, validate technology stacks, and make confident, well-informed transactions.

HORIZON-X is a dual-use, AI-native Software-as-a-Service (SaaS) platform, delivered via a secure web browser, that enables Systems Assurance, Supply Chain, Foreign Ownership, Control, or Influence (FOCI), and Regulatory Risk Management for Physical AI, Autonomous Vehicles, and Robotics (PAI-AVR).
HORIZON-X provides end-to-end risk analysis across the full PAI-AVR technology stack — including Hardware, Firmware, Operating Systems, Middleware, AI/ML SDKs (Perception, Planning, and Control), and AI Simulation, Training, and Testing environments — delivering system-wide visibility into mission-critical risks across complex, safety-critical systems.
Practitioner-Led Services: Fidelitas Defense also delivers Practitioner-Led Assurance, Risk Assessment, and Training Services, bringing real-world operational expertise to customers operating in high-consequence and regulated environments.
