Since 2018, we have been monitoring the evolving nature of company enterprise networks via our WAN Supervisor Survey. On this seventh version, we collected 52 survey responses and performed 13 interviews with WAN managers for extra perception into their network-related choices and techniques.
Here is what we have seen since we began the WAN Supervisor Survey: Over the previous decade, a number of forces have converged to push enterprises to rethink how they join company places of work around the globe. The institution of SD-WAN as an ordinary community know-how, the substitute of MPLS service with extra inexpensive web, the migration of apps and knowledge to the cloud, and the modifications in safety methods enabled by the SASE framework have created a dynamic, although advanced setting within the company extensive space community (WAN) area. Now, AI would possibly come alongside and additional change how enterprises handle their WAN and the way they want to connect with sources.
This weblog publish shares some top-level insights from the WAN Supervisor Survey outcomes, however the full report is a part of our Cloud and WAN Analysis Service platform. You may also obtain the manager abstract of the WAN Supervisor Survey right here.
Need extra WAN? Be part of Greg Bryan for Lightyear’s webinar discussing among the findings from our WAN Supervisor Survey and Lightyear’s State of Connectivity Report on April 2, 2026 at 1:00 pm ET.
On this weblog publish:
Key findings
-
The company WAN transformation has totally materialized, characterised by the definitive decline of MPLS (right down to a median of twenty-two% of websites) and the dominance of Direct Web Entry (DIA), which connects 54% of websites.
-
Bandwidth demand is surging towards GigE speeds and above, pushed by cloud connectivity and voice/video providers.
-
SD-WAN is now the usual community know-how, deployed by 63% of respondents, whereas safety has quickly shifted towards the Safe Entry Service Edge (SASE) and Zero Belief frameworks.
-
MPLS stays primarily for geopolitical, reliability, and particular high quality of service wants, and rising applied sciences like AIOps and Community-as-a-Service (NaaS) stay area of interest however are slowly rising.
Community configurations
Enterprises have firmly shifted away from costly MPLS providers towards hybrid networks prioritizing web connectivity. This transformation aligns with the widespread adoption of SD-WAN, a continued migration to the cloud, and the implementation of novel safety frameworks to safe native web breakouts.
Underlay within the SD-WAN age: Product combine and bandwidth demand
Hybrid networks are the usual, with DIA rising as the most typical underlay, utilized at a median of 54% of websites and by 96% of respondents. Bandwidth calls for have grown considerably since 2018, shrinking the footprint of small circuits (50 Mbps or under) and massively growing the deployment of GigE ports and above. This bandwidth demand is primarily pushed by entry to cloud sources, SaaS, and voice/video functions, whereas AI isn’t but a major driver for traditional workplace bandwidth.
MPLS
Regardless of its decline, 74% of respondents nonetheless use MPLS at a few of their websites, primarily resulting from lengthy transition instances, particular High quality of Service (QoS) necessities, and personal community safety wants. Geography is a significant component, with organizations closely retaining MPLS in areas like China and Africa to navigate geopolitical challenges, poor web choices, and regulatory complexities.
Satellite tv for pc
Satellite tv for pc stays a connectivity choice of final resort, averaging lower than 2% of complete enterprise websites. It’s deployed primarily when no wireline service is accessible, in extraordinarily distant areas (just like the Amazon rainforest), or as a backup for catastrophe resilience. Whereas Starlink at the moment dominates, enterprises are eagerly anticipating enterprise-grade Low Earth Orbit (LEO) rivals like Amazon Kuiper and Rivada.
Community administration
Most enterprise networks characteristic some stage of exterior administration, with solely about one third working completely unmanaged networks. Absolutely managed networks (42%) and co-managed networks (25%) are usually sourced instantly from the underlying service supplier. Administration technique is closely dictated by inner group dimension: smaller groups outsource to MSPs, whereas bigger groups are likely to insource and function “like an ISP”.

Overlay, safety, and AIOps
Pushed by the pandemic-accelerated shift to distant work and cloud providers, the main target of the WAN has decisively shifted towards safety. SD-WAN is broadly deployed and integrating with SASE architectures to guard trendy enterprise networks. In the meantime, AIOps is simply starting to emerge as a instrument for community administration.
SD-WAN
SD-WAN is firmly the usual, with 63% of enterprises having it deployed and one other 15% at the moment rolling it out. Organizations worth SD-WAN for offering operational agility, standardizing world providers, and serving because the foundational block to allow native web breakouts. Whereas some debate its long-term relevance towards endpoint-based SASE, it stays important for bodily department places of work and managing IoT gadgets.
Safety
Enterprises are quickly adopting the SASE framework, with 53% having already carried out components and one other 23% within the strategy of doing so. Subsequent-Era Firewall-as-a-Service (82%) and Zero Belief Community Entry (ZTNA) (79%) are essentially the most broadly adopted components. ZTNA is closely utilized to interchange legacy VPNs and allow safe native web breakouts, shifting safety from a fringe mannequin to a “by no means belief, at all times confirm” posture.
AIOps
AIOps instruments are within the very early phases of enterprise adoption, with solely 17% of respondents having deployed them. Early adopters use these instruments primarily to ingest and correlate cross-vendor telemetry, fixing the “swivel chair” downside for Community Operations Middle (NOC) engineers attempting to troubleshoot advanced points.
The necessity to join company places of work to a number of cloud suppliers has considerably elevated community complexity, pushing managers to adapt their ecosystems and contemplate on-demand networking applied sciences.
The market has seen an enormous shift away from strictly on-premises infrastructure. Whereas 75% of respondents nonetheless preserve some on-premises knowledge facilities, the overwhelming majority use a mixture of off-premises choices, with public cloud (60%) and personal cloud (58%) being almost equally common.
NaaS adoption stays flat at 17%, with one other 20% having researched the know-how and determined to not use it. Its major use case is offering cloud connectivity and knowledge middle interconnection materials (like Equinix Cloth) with out bodily provisioning. Nonetheless, adoption is restricted by strict company encryption wants that forestall using shared digital circuits, in addition to competitors from hyperscalers constructing their very own direct connection infrastructure.
