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.
Why now
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.
The role model
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.
Build & run
We don’t hand over a slide deck and leave.
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
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
