SD-WAN Consolidation Accelerates as Enterprises Cut Vendor Sprawl
Network teams are collapsing five-vendor WAN stacks into one or two platforms to simplify operations and cut licensing cost.
Software-defined WAN was one of the fastest-adopted networking technologies of the past decade. Many enterprises ended up with more than one platform — through acquisitions, regional decisions or separate projects. Consolidation onto a single vendor is now accelerating.
How sprawl happened
SD-WAN often arrived through individual business units or regions, each choosing what suited them at the time. Mergers added more platforms. The result in many organisations is two, three or even four SD-WAN systems, each with its own management console, policies and support contract.
“We had a different SD-WAN in every region. Every global policy change meant four separate projects.”
Why consolidate now
- Contract renewals offering a natural point to switch
- Security convergence, as SD-WAN merges into broader SASE platforms
- Shortage of engineers able to support multiple vendors
- Pressure to reduce licensing and support costs
The trade-offs
Consolidation reduces complexity but increases dependence on a single supplier. Network leaders recommend negotiating strong service levels, clear exit terms and price protection before committing the entire estate to one platform.
A chance to clean up
Migration projects also offer an opportunity to remove outdated routing policies, unused circuits and legacy configurations. Teams that treat consolidation as a redesign rather than a lift-and-shift typically end up with a simpler, more secure network.
For CIOs, SD-WAN consolidation is increasingly part of a larger decision about how networking and security will be delivered over the next five years.
