Integration fabrics for public sector.

Cross-department and central-to-local connectivity on a governed, open-standards fabric. Service Standard-aligned, accredited, built to survive machinery-of-government changes.

Overview

Integration fabrics infrastructure for public sector, built to the standard institutions in this sector are required to operate.

XVICA designs, builds, and operates this layer for public sector clients in the UK, US, Canada, and Australia. The work is specified against the regulatory regime, the operational profile, and the examination expectations of this sector before any code is written.

01Why it matters

What public sector cannot get wrong here.

Cross-department integration has failed repeatedly at high profile.
Machinery-of-government changes redraw ownership without notice.
Supplier lock-in at the integration layer survives Ministerial changes.
Legacy mainframe and bespoke systems persist for good reasons and must be integrated, not replaced.

02Regulatory posture

Named regimes, mapped controls

Regulatory requirements are translated into explicit control requirements, then mapped to tests and evidence collection. Nothing is implied.

Government frameworks

Service Standard, Technology Code of Practice, Secure by Design, GDS open-standards principles, and departmental accreditation regimes.

Data & privacy

UK GDPR, Digital Economy Act 2017 data-sharing powers, and DPIAs for cross-department flows.

Security assurance

OFFICIAL-SENSITIVE by default; accredited infrastructure for higher classifications.

03Reference architecture

Design decisions distinctive to this intersection

Components and design choices that recur across our work for this sector. Each deployment is specified individually.

Open-standards protocols

OpenAPI, AsyncAPI, OIDC, SAML, and published schemas. No proprietary contracts that outlive the supplier relationship.

Cross-department federation

Each department retains authority over its own data; the fabric enforces sharing contracts expressed as policy-as-code.

Legacy integration without disruption

Mainframe and bespoke systems are integrated through the fabric; sunset decisions are separate from the integration decision.

Observability in customer-owned stack

Departments keep their own telemetry. No central black box. Each department can answer its own Parliamentary question.

Supplier-substitutable

Published contracts and schemas mean a supplier change does not mean a rebuild.

04XVICA's approach

How we work in public sector.

Public-sector integration has failed enough times in public that the failure modes are well understood: supplier lock-in, cross-department political friction, and machinery-of-government changes that leave in-flight programmes orphaned. Our approach designs around those failures rather than against them. Contracts between systems are open, published, and substitutable; each department retains authority over its own data and its own observability; the fabric enforces the sharing agreement rather than owning the data. That discipline means a machinery-of-government change moves a service between departments without rebuilding its integration layer, a supplier change replaces an implementation without replacing a standard, and the National Audit Office can trace a cross-department flow without requesting bespoke tooling.
