Service · SIAM as Independent Integrator

The integration layer your multi-vendor IT actually needs.

We act as your independent SIAM integrator — sitting between you and your suppliers, governing the end-to-end service, and staying through run. No tooling lock-in. No supplier we secretly want to protect.

Hybrid IT broke the single-supplier model.

SIAM is the discipline that puts the client back in control of a multi-vendor estate — without taking the work back in-house.

  • You have 4+ suppliers, but no one owns the end-to-end service.
  • Tickets bounce between vendors. Time-to-resolve is rising.
  • Your largest supplier is also the integrator. The conflict shows.
  • Cloud, legacy and managed services don’t share a single service model.
  • Audit findings on supplier oversight (NIS2, DORA) are stacking up.

Independent. By design — not by accident.

We don’t sell towers. We don’t resell tooling. That independence is why our SIAM design holds up under audit — and why suppliers actually accept the governance.

Retained client

Owns strategy, demand, budget and outcomes. Stays small and senior.

Independent SIAM (Xedis)

Governs the end-to-end service. Owns process, data, escalation, supplier performance.

Service providers

Deliver towers (cloud, network, apps, EUC, security). Accountable on SLAs that finally connect.

We don’t hand over a slide deck and leave.

Build

Design the integration layer

  • Service model & supplier landscape map
  • Process design across incident, change, problem, request
  • Tooling architecture (ITSM-of-record + supplier exchange)
  • Governance forums, RACI and escalation paths
  • Contract & OLA alignment with existing supplier contracts
Run

Operate it as a service

  • Service integration management (SIM) team — embedded or remote
  • Supplier performance management with monthly service reviews
  • End-to-end incident & major-incident coordination
  • Continuous improvement backlog with measurable outcomes
  • Audit-ready evidence for NIS2 / DORA supplier oversight

Outcomes — not just a SIAM operating model on paper.

End-to-end

Single accountable view across all suppliers

Audit-ready

Supplier oversight evidence for NIS2 & DORA

Lower MTTR

Major incidents coordinated by one team

Vendor-neutral

Decisions taken on outcomes — not loyalty

Foundation for run.
