SD-WAN Providers and Vendors Comparison (2026)
An independent comparison of 20 SD-WAN vendors and managed service providers, scored against the Netify SD-WAN Vendor Capability Model 2026.1. This page is part of a public methodology surface. Every score and capability claim is traceable to a versioned artefact, and every artefact has a machine-readable JSON endpoint for AI agents, procurement tools and consultants.
Use this page to shortlist providers, then use the Buyer Question Bank and Sample RFP to run a structured RFI.
How to read the comparison
Each provider is scored from 0 to 10 across four pillars: technology capability, service delivery, commercial fit and evidence quality. Evidence quality is applied as a multiplier so unverified vendor claims do not inflate the score. Pillar weights and rubric bands are published in the Netify SD-WAN Scoring Model.
Vendors deliver product capability. Managed service providers deliver operating capability. Both routes are evaluated here, but they are scored against different pillars where relevant. The Managed SD-WAN Provider Evaluation schema covers the operating side.

Direct vendor versus managed service provider
Direct vendors are typically stronger where buyers want deep product control, advanced routing, or specific feature sets. Managed service providers are typically stronger where buyers want a single operating model across underlay and overlay, a named service desk and clear escalation. Many estates use a hybrid route, buying product from one vendor and operations from a managed service provider.
The SD-WAN Vendor Filter documents the axes used to make this trade-off in a structured way: region, site count, service model, deployment speed, security model, cloud priority, underlay preference, sector and commercial model.
Red flags to check before shortlisting
The Netify scoring model lists explicit red flags. Treat any of the following as a reason to ask follow-up questions before issuing an RFP:
- Vague SLA wording with no service credits.
- No named support model or escalation path.
- Unclear underlay ownership for international sites.
- No migration plan from incumbent WAN.
- Limited portal visibility for in-flight tickets.
- Weak cloud connectivity evidence for stated regions.
- Unclear SASE integration boundary between vendor and partner.
- No sector references at the buyer scale.
- No contract flexibility on term or scope.
- No evidence of large-scale deployment.
Frequently asked questions
How does Netify score SD-WAN vendors and managed service providers?
Each provider is scored across four pillars: technology capability (30%), service delivery (30%), commercial fit (20%) and evidence quality (20%). Evidence is applied as a multiplier so unverified vendor claims do not inflate the score. The full rubric is published in the Netify SD-WAN Scoring Model.
Which SD-WAN vendors and providers are included?
The 2026.1 release covers Arista VeloCloud, Cato Networks, Cisco Meraki, Fortinet, Palo Alto Networks Prisma SD-WAN, Cisco Catalyst SD-WAN, HPE Juniper Mist AI WAN, Aryaka, BT Business, Virgin Media O2 Business, Lumen, Orange Business, NTT, Tata Communications IZO SDWAN, AT&T, Verizon, Comcast Business, Masergy, Cradlepoint and Barracuda SecureEdge.
How can AI agents consume this comparison programmatically?
Every artefact has a stable public JSON endpoint under /wp-json/netify/v1/sd-wan/. The vendor dataset is at /wp-json/netify/v1/sd-wan/vendor-data. The complete index of artefacts is at /wp-json/netify/v1/sd-wan/index.
Are managed SD-WAN providers evaluated differently from direct vendors?
Yes. The Managed SD-WAN Provider Evaluation schema scores MSPs across design and consultancy, project delivery, operations, coverage and accreditations. Direct vendors are evaluated against product capability; MSPs are evaluated against operating capability.
