Defence and public sector
Cortex delivers frontier AI to government, defence, and intelligence users on secure infrastructure, from accredited commercial cloud to air-gapped deployment on classified networks. Your data, your analytical edge, and your operational picture stay inside your perimeter.
Sovereign deployment is the entry requirement, not the proposition. Cortex meets it at every posture, up to air-gapped operation on classified networks.
The proposition is what runs inside that boundary: cutting-edge agentic analytics that stays current as models advance, designed from the ground up to be safe in high-consequence environments. Your analysts build and operate it. The learning, the enrichment, and the accumulated analytical edge belong to you and never leave.
One platform. Three products. Deployable from departmental cloud to classified networks.
Secure multi-model AI for staff work. Document intelligence, drafting, and research across frontier and open-weight models, with full audit logging, access controls, and attribution protection. The everyday capability your people already want, inside a boundary you approve.
Agentic analytics across your data. Ingest documents, feeds, comms, and archives; enrich at scale; query in natural language. Your analysts build and operate it themselves. No forward-deployed engineers required.
Sovereign AI for classified environments. The defence suite: open source intelligence, knowledge management, accelerated planning cycles, HQ staff process enrichment, and information operations tooling. Deployable across UK government networks at every classification level.
Cortex is model agnostic and infrastructure agnostic. The platform runs the models your requirement calls for, frontier or open-weight, on infrastructure you approve, and moves between postures as requirements change.
Attribution-protected access to frontier capability, built on deep expertise in anonymised internet routing. No query can be linked to your organisation.
Dedicated environment on accredited commercial cloud or assured sovereign infrastructure. No data reaches any AI vendor.
Deployed on infrastructure of your choosing. Air-gap capable. Full customer control.
Deployment matches your assurance requirements, not the other way around.
The same platform serves the wider public sector. Arc gives departments secure, audited access to frontier AI for everyday work: drafting, research, and document intelligence at scale. Vantage gives analytical capability that has historically been priced out of reach for civil departments and the NHS. The assurance case built for defence is the same one that answers a departmental security review.
Founded and led by UK defence and intelligence specialists, with service in specialist units and wider elements of government security. Security cleared team, able to engage at the levels your work requires.
Cyber Essentials Plus certified. ISO 27001 and Defence Cyber Certification in progress. Security by Design documentation maintained as standard practice, not produced on request.
Sovereignty. Assurance. Safety. The customer keeps control of data, jurisdiction, and infrastructure. Architectural guarantees, not policies layered on top: no attribution, no training, demonstrable isolation.
Cortex is UK-incorporated and UK-operated. We work within MOD and government commercial routes and can engage from initial assessment through to accredited deployment.
If your organisation is assessing how to bring AI capability inside its perimeter, we can walk you through the architecture, the deployment postures, and what accreditation looks like in practice.
