Secure Inter-Agency
Data Exchange
A proprietary cross-agency data exchange platform for Western Australian government departments — enabling auditable, encrypted sharing of sensitive data across agency boundaries with granular access control and immutable audit trails.
Government data that needs to move — securely
Western Australian government agencies hold significant volumes of sensitive data — citizen records, enforcement data, health information, compliance records. Effective government functions require that relevant information can be shared across agency boundaries in real time.
The challenge is doing this without compromising the sovereignty, security or auditability of that data. Off-the-shelf platforms designed for commercial use lack the access model, audit capability and data residency controls that government contexts demand.
Our client required a system that could facilitate multi-agency data sharing under tightly controlled access policies, with a complete audit trail for every data access event, and compliance with WA government data handling standards.
Every access event is intentional, recorded and attributable
The platform is built around the principle that data access must always be justified, authorised and documented — not just technically controlled, but operationally meaningful.
Attribute-Based Access Control
Access policies are expressed at the field level, not just the object level. A user may be authorised to view a record but not certain sensitive fields within it. Policies are managed centrally and enforced at the API boundary — not client-side.
End-to-End Encryption
Data is encrypted in transit and at rest, with key management separated from data storage. Each agency retains control over keys for their own data, and cross-agency sharing uses short-lived delegated keys that expire automatically.
Immutable Audit Logs
Every access event — query, read, export, modification — is written to an append-only audit store that cannot be altered by ordinary system operations. Audit logs are replicated independently and can be provided to oversight bodies on demand.
Data Residency Controls
The platform enforces WA-based data residency for all sensitive data. Replication, backup and processing pathways are constrained to compliant infrastructure. Cross-border transfers are blocked at the platform level, not just by policy.
