AI governance that survives the audit.In every jurisdiction you operate.
Sentinel ships as one platform with jurisdiction-specific framework packs. NSW AIAF, EU AI Act, Texas TRAIGA, Korea AI Basic Act, Japan AI Promotion Act, China's layered AI regime, and the rest — encoded as data, cross-mapped on day one. Available now for NSW councils; rapid expansion across Australia and globally.
The 2025 AG report didn't ask if you use AI. It assumed you do.
The NSW Auditor-General's 2025 Local Government report set the bar: a documented AI strategy, an inventory of every AI tool in use, transparency to residents, and per-use-case risk assessment under the NSW AI Assessment Framework.
Every council in NSW is reading it this year. None of them have eighteen months.
Eight modules. One evidence trail. Every artefact the AG will ask for.
Sentinel mirrors the structure of a real council AI governance programme — built from a five-day sprint methodology designed for the audit, procurement and governance realities of NSW councils.
AI Use-Case Register
Every AI tool, model and shadow use — classified, tagged, owned.
AIAF Workpapers
Per-use-case NSW AIAF assessment, with privacy and records sign-off queues built in.
AIRC Workflow
AI Review Committee charter, agendas, decisions, gates G0 through G4.
Risk Register
Top AI risks, mapped to each use case, with mitigations, owners and review dates.
Transparency Register
Resident-facing register on your council subdomain, generated from approved use cases.
AG Gap Tracker
Pre-loaded with the 2025 AG findings — close them with owner, action, evidence.
Evidence Vault + Audit Log
Append-only, hash-chained, 7-year retention. One-click auditor export.
Re-attestation Engine
Annual re-approval cycles, drift prompts, automatic AIRC re-submission at G4.
From shadow tool to signed-off pilot — in one flow.
Every AI use case passes through five gates. Sentinel runs the full path: intake, assessment, approval, monitoring, and annual re-attestation. Nothing slips through the cracks because nothing exists outside the system.
Intake
Owner submits a short form. System assigns a provisional risk tier.
AIAF assessment
Workpaper completed; privacy, records and risk sign-off captured.
Pilot go-live
AIRC approves with conditions; evidence pack generated automatically.
Scale or stop
Evidence reviewed against thresholds. Decision recorded with conditions.
Re-attest
Annual delta workpaper. AIRC re-approves or sunsets the use case.
Frameworks as data. Cross-mapping for free.
The frameworks an auditor cares about — NSW AIAF, ISO 42001, NIST AI RMF, OECD principles, the AG findings — are encoded as data inside Sentinel, with stable IDs and explicit cross-maps.
When you assess a use case, Sentinel deterministically knows which clauses apply, what evidence each requires, and how to render the auditor's view. The workpaper, the AIRC pack and the evidence export are generated, not authored from scratch.
- ✓When AIAF v2 ships, your existing workpapers re-map automatically.
- ✓When VIC or QLD release their own framework, we ship a pack — no re-platform.
- ✓When the AG asks for evidence, it’s already structured the way they want it.

A single clause definition — versioned, cross-mapped, machine-readable.
One platform. Every framework. From NSW councils to the EU AI Act.
Sentinel ships as one platform with jurisdiction-specific framework packs. Available now for NSW local councils. Pipeline for VIC, QLD and the AU private sector. On the roadmap for the rest of the world — and the Framework Engine supports them from day one.
Australian Local Government — every state & territory
Private Sector — Australia & international
Your council's data stays in Australia. Full stop.
We built Sentinel for the procurement reality of NSW local government — not for US SaaS economics. Sovereign hosting, M365 SSO, IRAP-aligned controls, and tenancy isolation are part of the architecture, not an enterprise add-on.
AWS Sydney only
All tenant data resides in ap-southeast-2. Backups stay in-region. Never crosses a border.
IRAP-aligned controls
Built to IRAP control set from day one. ISO 27001 certification on roadmap.
M365 / Entra SSO
No local passwords. Your council's identity provider, your council's MFA policy.
Append-only audit log
Hash-chained, exportable, 7-year retention. The AG's questions answer themselves.
Per-tenant isolation
Schema-per-tenant by default. Single-tenant deploy option for tier-1 councils.
AU-only AI services
Any internal AI assist runs on Azure OpenAI AU East. Prompts never reach US endpoints.
Priced for council IM&T budgets, not enterprise procurement.
Fixed-fee install + annual support. All tiers include unlimited users, full workspace, and quarterly framework updates. Choose the tier based on how hands-on you want Arrochar to be.

Built by the consultants delivering the manual version today.
Sentinel started as a five-day sprint methodology and a four-to-six-week agentic AI pilot, designed for the procurement, governance and audit realities of NSW councils. Every module of Sentinel mirrors an artefact from Arrochar's existing AI governance consulting practice.
The platform exists so the next 127 NSW councils don't each have to rebuild the same workpapers from scratch.
“The whole methodology — inventory, AIAF workpapers, AIRC charter, transparency register, gap closure against the AG report — delivered in seven weeks of elapsed time, audit-ready.”
