NAUTILUS INTERNATIONAL RISK CONSULTANTS LTD

What NAUTILUS INTERNATIONAL RISK CONSULTANTS LTD does

Nautilus International Risk Consultants Ltd is a UK private limited company founded in 2005 and headquartered in Poole, Dorset, that delivers accredited simulation training services and proprietary software primarily to military, law enforcement, civil nuclear, and emergency-services clients. Its core offering centres on five managed-service lines: JALO/US/NATO-accredited Joint Terminal Attack Controller (JTAC) simulation using deployable Cobra and Holovis domes (150°, 180°, and 240° field-of-view configurations) running Bohemia Interactive Simulations' VBS3/VBS4; simulated Intelligence, Surveillance and Reconnaissance (ISR) training streamed globally from accredited UK MOD servers; high-fidelity medical simulation using Laerdal SimMan 3G Trauma mannequins, SimBodies, and wearable wound effects; battlefield effects (BattSimFX) using RF-controlled IEDs, RPGs, mortars, and smoke/fire systems; and VirTra V-300 judgmental firearms training, for which Nautilus is the exclusive UK reseller.

The technology stack combines third-party platforms (BIS VBS, VirTra, Cobra, Holovis, Laerdal, Harris radios) with internally developed proprietary IP — notably Toolbox 3.0 VBS plugins, the Major Incident Response Application (MIRA) for civil nuclear, Shell Common Operating Picture software on Android devices, and the BloodWorks moulage system. The firm operates as a member of the BIS Developer Network, holds UK MOD server accreditation, and is certified to ISO 9001:2015 and Cyber Essentials Plus.

Commercially, Nautilus generates revenue through multi-year managed-service contracts, framework agreements, and direct tender wins with UK MOD (Strategic Command, 1 Artillery Brigade, 3 Commando Brigade, Royal Navy, RAF Regiment, British Army), the Canadian Department of Defence, the Metropolitan Police, NDA/NRS, NHS, and partners including Capita, Northrop Grumman, and HMGCC Co-Creation. Pricing is bespoke and not publicly disclosed; go-to-market relies on defence industry exhibitions (ITEC, DSEI, I/ITSEC), framework procurement, and direct enterprise sales. Over 60% of staff are Tri-service veterans and the team holds more than 160 years of combined military experience.
