Methodology

How the estimates were built: data sources, modelling approach and validation steps.

Research approach

A market size is a claim about the world, and a claim is only as good as the route to it. Every study is built upward from units and prices — what is actually produced, sold or performed, at what it actually changes hands for — rather than from a headline figure divided downwards. Disclosed company revenue is then used to check that build, not to produce it.

Market size estimation, this report

The estimate is built upward from the installed base of SD-WAN edge devices and managed connections in service each year, multiplied by the realised annual contract value per site across cloud-delivered and on-premise deployment models. Site counts are derived from enterprise WAN modernization and branch-refresh cycles tracked through carrier and systems-integrator project disclosures, while per-site pricing is anchored to published managed-service and license price lists from the leading platform vendors. This unit-and-price build is then checked against the SD-WAN and secure-access segment revenue that Cisco, VMware, Palo Alto Networks, Fortinet and Juniper report in their own quarterly filings. Where the two diverge, the site-count or per-site-price assumption feeding the bottom-up build is the one corrected, not the disclosed company revenue.

The four stages

The same sequence runs behind every published study, whatever the industry. The order matters as much as the steps: the segment axes are fixed before any number is collected, so the model is never reshaped to fit whatever data happens to turn up.

What the build rests on, and what checks it

The two are not interchangeable. The left column produces the number; the right column tests it. When the check disagrees with the build, the answer is to find which bottom-up assumption is wrong — a unit count, a price, a take-up rate — not to split the difference between them.

The bottom-up build rests on
  • Volume actually transacted — units produced, installed, dispensed or procedures performed, counted at the level each is genuinely recorded
  • Realised pricing by tier and channel, rather than one blended average applied across the whole market
  • Take-up and frequency: how much of the addressable base buys, and how often it repeats
The build is checked against
  • Disclosed revenue of the companies serving the market, where filings separate it far enough to be usable
  • Buyer-side spending totals — capital budgets, procurement lines, or the output of the end market the product is bought against
  • Trade and customs flows, where the product crosses borders in a separately recorded form

Data sources

Published data establishes what happened. Only the people transacting in a market can say why, and what is about to change — so the two are collected separately and weighted differently.

Primary — who is interviewed
  • Commercial and product leadership at the companies that supply the market
  • Procurement and specification leads at the organisations that buy it
  • Distributors, integrators and channel partners, where the market is served indirectly
  • Regulatory and standards specialists, where approval governs what can be sold at all
Secondary — what is read
  • Company filings, annual reports and investor disclosure
  • Government statistics, customs records and regulatory registers
  • Trade association output and standards-body publications
  • Technical and peer-reviewed literature, where the market rests on a clinical or engineering claim
Primary research design, this report

Interviews are weighted toward the buyers who actually sign SD-WAN contracts: enterprise network architects and IT infrastructure heads who select the platform, procurement and sourcing leads who negotiate managed-service terms, channel partners and systems integrators who deploy and support the connections, and telecom regulatory contacts in markets where cross-border data routing or licensed spectrum affects wireless WAN uptake. Sampling emphasises the United States and Western Europe, where enterprise WAN refresh cycles are most advanced and disclosure is richest, with additional weight given to China, India and Brazil to capture branch-network buildout in markets where mobile and broadband underlay is expanding fastest.

Secondary sources, this report

Desk research draws on the network-equipment and managed-service line items disclosed in the quarterly filings of Cisco, VMware, Palo Alto Networks, Fortinet, Juniper Networks and Nokia, cross-checked against MEF's SD-WAN service attestation registry and the ITU's fixed broadband and mobile-network deployment statistics that underpin transport-type assumptions. Customs classifications for networking appliances (HS code 8517.62) are used to sense-check on-premise hardware shipment volumes by country, and national telecom regulator filings in the United States, the European Union, India and Brazil supply broadband and LTE/5G coverage data used to weight the wireless-transport segment.

Desk research runs across proprietary research databases including Factiva, OneSource and Hoovers alongside the public sources above. Modelling and statistical validation are run in SAS and SPSS.

Forecasting

The forecast is not a growth rate applied to a base year. It is built from the drivers that are expected to change, each one stated so a reader can disagree with it.

Forecast approach, this report

The forecast carries forward the shift from appliance-based, on-premise SD-WAN toward cloud-delivered and SASE-converged delivery, and assumes enterprises with expiring MPLS contracts default to broadband or wireless underlay instead of renewing legacy circuits. Pricing is modelled as continuing to compress on a per-site basis as competition intensifies, offset by rising attach rates for security and managed-service add-ons. The 2026 estimate normalises for the post-pandemic remote-access surge that inflated 2021-2022 growth rates, treating that period as a one-time acceleration, not the market's underlying pace of growth. The forecast holds only if enterprise WAN refresh cycles continue on their current multi-year cadence and broadband and wireless underlay capacity keeps expanding in the markets assumed to adopt it.

Triangulation and validation

No figure enters a report on the strength of one source. Where the two sizing routes disagree the difference is not averaged away — the assumption causing it is isolated, tested against a third independent measure, and either corrected or carried forward as a stated limitation. Historical years are back-tested against the growth actually recorded before any forecast is allowed to run forward from them.

Validation, this report

Historical 2020-2024 figures are back-tested against the WAN-edge and SASE segment growth rates that Cisco, Palo Alto Networks and Fortinet have already reported for those years, and the resulting bottom-up path is required to track those disclosed rates within a narrow margin before being carried into the forecast. Segment-share shifts, particularly cloud's rising share of deployment type and MPLS's declining share of transport type, are reviewed against channel-partner and systems-integrator input on actual deployment mix. Sensitivities were run on per-site pricing and on the pace of MPLS-to-broadband migration, since those two assumptions move the forecast total more than any other single input.

Confidence and limitations

Where an estimate is firm and where it is not is stated rather than left to be inferred from the precision of the number.

Confidence framing, this report

Confidence is firmest for the cloud-versus-on-premise deployment split and for North America and Western Europe revenue, where platform-vendor disclosures and channel data are richest. It is thinner for the Middle East and Africa and for Latin America outside Brazil and Mexico, where managed-service contract values are less consistently disclosed and the estimate leans more on regional carrier partnerships and adjacent networking-market analogues. The organization-size split for small and mid-sized enterprises also carries more uncertainty, since many buy SD-WAN bundled inside a broader managed-service contract that does not break the connectivity component out separately. A faster-than-assumed MPLS retirement cycle is the clearest structural risk to the forecast.
