The Sovereign AI Platform
The AI advantage.
Without the exposure.
We orchestrate secure AI across your whole organisation, from confidential chat and document intelligence to full analytical pipelines.
Why Cortex exists
The AI transition is here.
Harness it with confidence.
When you send a query to a commercial AI provider, you're telling them who you are, what you're working on, and how you think. Your prompts are logged, your identity is visible, and your data is retained under their legal obligations, not yours. For organisations handling sensitive information, that exposure is unacceptable.
The productivity gap widens every day. The organisations using AI effectively are compressing weeks of work into hours. For those who can't use commercial platforms, that gap is growing.
We believe no organisation should have to choose between the benefits of AI and the confidentiality of their work.
One platform. Four products.
Built for the environments where security is not optional.
Arc
Familiar AI chat and document intelligence. Confidential by design.
Vantage
An agentic analytics platform. Data ingestion, pipelines, structured outputs and complex workflows on your data.
Palisade
Sovereign AI aligned to classification requirements. From OFFICIAL-SENSITIVE through to SECRET and above.
Atom
A self-contained, portable AI deployment. Document intelligence and analytics with no external dependencies.
ARCFamiliar AI. Confidential by design.
Arc delivers frontier AI through a familiar interface. Chat, document intelligence and multi-language support, with confidentiality and attribution protection built in at every layer.
- Confidential AI chat across all frontier models
- Document intelligence: query, synthesise and surface insights from your files
- Multi-language support across 90+ languages
- Shared filesets, team projects and audit logs
- Deployment options from shared cloud to air-gapped
Arc is complete at every tier. Starter, Team and Enterprise. The progression reflects scale and compliance requirements, not access to capability.

Cortex delivers frontier AI capability to UK government and defence, across classification levels. Alongside frontier AI chat and document intelligence, Cortex has developed specialist capabilities for government knowledge management, and for defence: capabilities to accelerate planning cycles, enrich HQ staff processes and tools for information operations.
We welcome enquiries from government and defence organisations and their supply chains.
Deployment
Built for your security posture.
One platform. Three ways to deploy it, each built for a different security posture.
Incognito
Queries routed through Cortex infrastructure with full attribution protection. Your organisation is never identifiable as the source.
Enclave
AI processing runs inside a dedicated private cloud environment. Queries never reach AI company systems.
Sovereign
Deployed on client-owned infrastructure or a private network. No external dependencies. Air-gapped capable.
Our guarantees
Security as architecture.
Not policy.
No attribution
Your organisation can never be identified as the source of a query. By design, not policy.
No training. Ever.
Your prompts are logged and aggregated. Your data is never used to train or improve any model. Guaranteed contractually.
Your deployment, your rules
From shared sovereign cloud to fully air-gapped. The architecture matches your requirements, not the other way around.
