Public AI providers route through US/Western servers. Your classified and sensitive data crosses borders without your consent.

Standard AI platforms log nothing you can take to a tribunal or inquiry. For government work, that's a liability.

Civil servants paste sensitive material into public AI tools. There's no way to enforce who sees what across departments.

Classified and sensitive data is completely isolated from public AI providers. Your prompts are anonymised, routed through a privacy layer, and zero-retention policies are enforced by default. No training on government data. Period.

Deploy Centurion on your own infrastructure — on-prem, sovereign cloud, within your jurisdiction. Nothing leaves your control. Meet UK OFFICIAL/SECRET requirements, EU data residency, and Five Eyes alignment out of the box.

Every single action — every prompt, every document access, every share — is cryptographically signed to an immutable ledger. Tamper-proof audit trail that satisfies public inquiry, freedom of information, and internal investigation requirements.

Create secure compartmentalised workspaces across departments, agencies, and approved contractors. Military-grade access controls. Nothing shared without explicit ministerial or permanent secretary level approval.

Your relationship with Centurion builds over time. It remembers the policy documents you reviewed six months ago, the analysis you moved on from, and the context of every decision. This institutional memory persists across LLM providers — switch models freely without losing your history. The memory stays encrypted on your infrastructure. Public AI providers never see it.

A policy team analyses 10,000 public consultation responses. Centurion handles the analysis on a locked-down server. No data leaves the building. The blockchain records every query for audit purposes. The final report is generated with full provenance showing exactly which data informed which conclusion.

Home Office, Cabinet Office, and HMRC collaborate on a joint operation. Each department's Centurion operates in its own security compartment. Only pre-approved documents cross the boundary, with every access logged to the immutable ledger.

A minister receives a daily AI-assisted briefing prepared by their team. The Centurion that prepares it runs on a secure government server. The briefing is generated, encrypted, and delivered — never touching a public AI provider.
