What Global Nuclear Security Partners does

Global Nuclear Security Partners (GNSP) is a privately held nuclear security consultancy headquartered in London with a regional subsidiary in Adelaide, Australia. Founded in 2021, the firm provides advisory and assurance services across six pillars: Defence Nuclear; Civil Nuclear; Training & Independent Assurance; International Architecture & Safeguards; Emerging Technologies (SMR, AMR, fusion); and Radiological Survey & Reconnaissance. Its technology stack centres on a high-precision radiological survey offering (mapping, imaging, subsurface and structural assessment, post-processing and analysis) and a trademarked proprietary resilience wargaming methodology, REDFLAG™. GNSP holds observer status with the IAEA's International Nuclear Security Education Network (INSEN), described as a first for a nuclear security consultancy, and engages with international standard-setters including WINS and the International Nuclear Security Forum.

The company operates a B2B professional services model, delivering bespoke consulting engagements to government defence organisations, civil nuclear operators, and pre-nuclear nations across the UK, Australia, and the US. Distribution is partnership-led rather than headcount-led: GNSP pairs with Cogent Security LLC for US reach (active with US DOE NNSA), Nuclear Training Services for in-person course delivery, the South West Nuclear Hub for research and skills, Nuclear Consulting for engineering and project delivery, and Becrypt for cyber and information assurance. Pricing is not publicly disclosed and is structured around project scope, complexity, and client requirements. Revenue is not publicly reported; the firm has 9 employees as listed in the firmographic record.

GNSP markets primarily through its website (gnsp.global) and professional social channels (LinkedIn, Twitter/X), with direct enquiry funnels via [email protected] and [email protected]. Customer segments span civil nuclear organisations across the fuel cycle, defence nuclear agencies, pre-nuclear nations needing non-proliferation education, and advanced nuclear technology developers (SMR, AMR, fusion) requiring security support for licensing and commercial deployment. The operating model combines direct advisory with productised training (REDFLAG™) and partner-enabled delivery to scale beyond the small core team.
