Integration fabrics for enterprise.

One governed layer across ERP, SaaS, legacy middleware, EDI, and industry protocols. Observable, reversible, built for incremental modernisation.

Overview

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

XVICA designs, builds, and operates this layer for enterprise 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 enterprise cannot get wrong here.

ESBs installed a decade ago are now a concentration risk.
EDI, legacy middleware, and SaaS connectors are maintained by different teams with different standards.
A change in one supplier breaks an integration nobody remembers owning.
Modernisation programmes fail in the integration layer, not the target platform.

02Regulatory posture

Named regimes, mapped controls

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

Information security

ISO 27001, SOC 2 Type II, and sector overlays (IEC 62443 for industrial, NERC CIP for energy).

Data protection

GDPR Article 28 processor obligations, UK DPA 2018, CCPA, and cross-border transfer constraints.

Commercial & audit

SOX s.404 controls over interface-dependent financial data, supplier audit rights, and SLAs embedded in commercial contracts.

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.

Protocol coverage

REST, gRPC, GraphQL, SOAP, WebSockets, AMQP, Kafka, MQTT, SFTP, AS2, EDI X12 / EDIFACT — first-class, not adapter-of-last-resort.

Dead-letter and replay built in

Every flow has a documented dead-letter path and a reviewed replay procedure — not a post-incident scramble.

Per-integration policy

Access, rate limits, data classification, and audit are policy-as-code per flow. Not a platform-wide averaging.

Legacy coexistence

Existing ESB, iPaaS, and bespoke middleware stay in place where it is safer to route new work through the fabric than to rip them out.

Observability as a right

OpenTelemetry traces, logs, and metrics in the customer-owned stack. No proprietary black boxes.

04XVICA's approach

How we work in enterprise.

Enterprise integration estates are archaeological. Our approach is archaeological too: understand what is in place, classify by operational risk and strategic value, and route new work through a governed fabric rather than building a twelfth point-to-point. What is safer to keep, keeps running; what is routed through the fabric gains observability, policy enforcement, and a retirement plan. Integrations move from tribal knowledge to documented assets; replay and dead-letter handling stop being incident-time improvisations. The modernisation programme that historically stalled at integration finds the path cleared because the integration layer is no longer where risk accumulates unseen. The estate is not rebuilt; it is brought under governance one flow at a time, with reversible decisions throughout.
