With a new normal of hybrid work established, trends in network services are once again changing. But unlike the shifts we saw in 2020, this time trends are fueled by technology and innovation—not huge outside forces like a global pandemic.
The modern wide area network (WAN) is evolving within a dynamic, complex environment.
How so? I could point to the establishment of SD-WAN as a standard network technology, the replacement of MPLS service with more affordable internet, the migration of apps and data to the cloud, or changes in security strategies enabled by SASE framework—just to name a few factors.
With the release of our latest WAN Manager Survey—available to all of our Cloud and WAN Research Service subscribers—we wanted to highlight seven major takeaways from our current data.
Respondents say they're using DIA at an average of 49% of sites compared to 41% for MPLS.
All port/circuit speed ranges at 50 Mbps and below have shrunk over the past five years. At the same time, all speeds above 50 Mbps have grown—often significantly.
MPLS users have been moving away from sourcing from a single global provider and toward a mix of global and regional providers.
SD-WAN has become the norm for enterprise networks, with 65% of respondents having installed an overlay on at least some part of their network and 51% at all or most of their sites.
SASE has hit the mainstream as well, with 53% of respondents having adopted at least some elements of the SASE framework.
While a strong majority of respondents have some on-premises data centers, nearly all of them also have data centers in the cloud.
NaaS remains a cutting-edge solution, with few respondents having already adopted it. Many of the enterprises we surveyed expressed skepticism about its potential use cases.

And if you prefer your data in deck form, I have great news.
I recently traveled to the Enterprise Network & Security Summit in Dallas to share these key trends. My session The Present and Future of the Enterprise WAN covers several of these major findings.
