Vigilante

What Vigilante does

Vigilante is a privately-held defense simulation and training software company headquartered in Lorena, Texas, with operations in Austin, TX. The firm builds products, content, and custom software primarily for U.S. and allied military and defense prime customers, with a stated roster that includes the U.S. Marine Corps, Air Force, Navy, Army, Space Force, the Jordanian Armed Forces, the UK Royal Air Force, the UK DSTL, and defense primes/adjacents such as L3Harris, BISim, Lockheed Martin, Microsoft, MAK Technologies, and Epic Games. Customer concentration is overwhelmingly government/defense, with no evident commercial diversification.

The product portfolio centers on a modular simulation platform called Defense Sim Pro (DSP), built on Unreal Engine with support for C++, Unity, VBS, and Frostbite, and compliant with DIS/HLA standards. Complementary offerings include DART (a software-only FPV drone trainer for commercial VR hardware), a 3D Asset Library of more than 180 DIS/HLA-compliant models, and a suite of professional services covering plugin development, AI/LLM implementation, real-world data integration, and high-fidelity content (MOCAP, Cesium terrain). The technology stack is engine-agnostic, standards-compliant, and oriented toward integration into larger simulation ecosystems rather than as a standalone proprietary runtime.

Vigilante monetizes through a mix of per-seat annual licensing for DART, platform licensing for DSP, direct commercial licensing of the 3D Asset Library (since the December 17, 2025 retirement of the marketplace channel), and bespoke software development services. Go-to-market combines direct sales to DoD service branches, channel partnerships (notably KBR as USMC TECOM lead integrator from April 28, 2026, and Virtuix for Omni One VR treadmill integration), and integration with established simulation primes such as BISim and L3Harris. The business model is therefore a hybrid of recurring licensing and project-based services, leaning on defense procurement and integrator relationships for scale.

Core offering

Vigilante builds custom immersive training software for the defense and space industry, anchored by two flagship products: DART (a software-only FPV drone trainer for military operator qualification) and Defense Sim Pro (a modular Unreal Engine-based simulation platform enabling military engineering teams to build, own, and sustain training applications). The company also delivers custom software development, AI/LLM integration, plugin development, real-world data integration, and high-fidelity 3D content services to defense organizations and primes.

Product overview

Vigilante offers a portfolio of training software solutions for high-stakes industries (defense, aerospace, healthcare, energy, transportation). The core products consist of DART, a standalone software-based FPV drone trainer for qualifying drone operators without proprietary hardware, and Defense Sim Pro (DSP), a modular simulation platform built on Unreal Engine that serves as the foundation for organizations to build, own, and sustain military training applications. Supporting services include custom software development (C++, Unreal Engine, Unity, VBS, Frostbite), AI and LLM implementation for adaptive training, plugin development, real-world data integration (Cesium terrain, satellite data), and Research & Development. High-Fidelity Content Services provides HLA/DIS-compliant 3D models, motion capture, technical art, and real terrain solutions. The company previously operated a Marketplace (now retired) offering free 3D models, though the full library (180+ military-grade models) remains available for government licensing.

Expansion highlights12 records

Broad incumbents

• SAIC: Large government IT and defense services integrator with a dedicated training and simulation practice. Competes with Vigilante for DoD simulation contracts at a vastly larger scale, often as a prime contractor on programs where Vigilante could be a sub-tier.
• Applied Research Associates (ARA): Scientific and engineering research firm that builds defense simulation, training, and intelligence products for the DoD. A bigger, broader incumbent that competes with Vigilante on military simulation and adaptive training work.
• CAE: Global defense and civil aviation training and simulation company offering immersive training systems across aviation, land, and maritime domains. CAE is a broad incumbent in the same military training market Vigilante serves, with far greater scale and a much larger program-of-record footprint.

Direct peers

• Dignitas Technologies: Defense-focused small business providing custom simulation, training, and analytics software for the U.S. Army and other DoD customers. Closely comparable to Vigilante in scale, customer base, and custom simulation development services model.
• SimIS: Defense simulation and training company specializing in modeling, simulation, and immersive training for the U.S. Navy and other DoD customers. Similar in size and mission to Vigilante, with comparable engineering services and platform offerings.
• MAK Technologies: Provider of DIS/HLA-compliant simulation software (MAK ONE) for military training and virtual experimentation. MAK is closely comparable to Vigilante's DSP offering and targets the same U.S. and allied defense customers, though with a longer-tenured installed base.
• Cole Engineering Services: Developer of integrated live, virtual, and constructive (LVC) training solutions for the U.S. Army and other defense customers. Operates similar end-to-end simulation engineering services as Vigilante, primarily for DoD model-and-simulation programs of record.
• Quantum3D: Independent provider of real-time visual simulation and training solutions for defense and aerospace, including DIS/HLA-compliant image generators and turn-key simulators. Direct competitor to Vigilante's high-fidelity content and simulation stack for military training applications.
• Bohemia Interactive Simulations (BISim): Subsidiary of BAE Systems and a leading provider of military simulation and training software (VBS). BISim is both a customer and a market competitor to Vigilante, addressing the same DoD and defense prime customer base with similar DIS/HLA-compliant simulation products.

Others

• Epic Games (Unreal Engine team): Parent of Unreal Engine on which Vigilante's DSP and DART are built. While a platform partner and public endorser, Epic Games is also an enabling technology provider whose future moves on licensing, royalties, or in-house defense simulation could materially affect Vigilante.
