How to choose a network & infrastructure provider
Enterprise network procurement now divides into three distinct buying motions. Vendor-led professional services arms (Cisco CX, Juniper Professional Services) deliver the deepest product expertise and are typically essential for greenfield builds on new platforms or major architecture transitions. Independent integrators (World Wide Technology, Presidio, Computacenter, CDW) compete on multi-vendor design, procurement leverage, and operational neutrality. Carrier-led providers (BT Business, Orange Business, Verizon Business, AT&T Business, Lumen Technologies) bundle managed connectivity with overlay services and remain dominant where international MPLS or last-mile aggregation is in scope.
SD-WAN has matured into a default rather than a project, and most net-new spend is moving into SASE — converging SD-WAN with cloud-delivered security (SSE) under a single policy plane. Buyers should test whether providers can deliver SASE as a true single-vendor stack or stitch best-of-breed components. Data centre work has shifted from physical refresh toward fabric automation, EVPN/VXLAN designs, and tighter integration with public cloud overlays. Wireless engagements increasingly demand AI-driven operations (Mist, Meraki, ArubaOS-CX) rather than controller-based architectures.
For the security overlay layer see cybersecurity services and identity and security consulting. For broader operational scope see managed IT services. To compare the underlying platforms see SD-WAN platforms, SASE platforms, and network monitoring tools.
Frequently Asked Questions
How much does a managed enterprise network engagement cost?
A multi-site managed network with SD-WAN typically runs $80-300 per site per month for connectivity orchestration plus $1,500-6,000 per site for one-off integration. Global SASE programmes for 5,000-25,000 employees usually land between $4M and $18M over three years, with overlay security forming 30-50% of that spend.
Should we use a carrier or independent integrator for SD-WAN?
Carriers (BT, Orange, Verizon, Lumen) bundle underlay connectivity with managed SD-WAN and simplify accountability for a single throat to choke. Independent integrators (WWT, Presidio, Computacenter) deliver more vendor neutrality and tougher procurement leverage. Most large enterprises use both — carrier underlay plus integrator-led overlay — to avoid lock-in on the policy layer.
Is SASE replacing standalone SD-WAN procurement?
For new buying decisions, yes. Single-vendor SASE (Palo Alto Prisma, Netskope, Zscaler, Cato) is now the default architecture for 2026 RFPs in 5,000+ seat enterprises. Standalone SD-WAN renewals are typically extended only where integrated security has already been committed elsewhere, or where data sovereignty constraints rule out cloud-delivered security.
How should we evaluate a network provider's automation capability?
Require: source-of-truth design (NetBox, Infoblox), reference network-as-code repositories using Ansible or Terraform, evidence of CI pipelines for network changes, and tested rollback procedures. Beware providers whose automation amounts to ticketing wrappers around manual CLI work. Mature providers can demonstrate change failure rates below 3% and mean-time-to-restore in minutes rather than hours.
What contract structure works best for managed networks?
Three to five year terms with annual commercial reviews and explicit benchmarking clauses. Tie a portion of fees to measurable SLOs (availability per site, change success rate, MTTR), not just availability SLAs. Avoid bundled hardware leases that lock in a single OEM beyond the refresh cycle and require provider-neutral exit clauses for source-of-truth data and configurations.
