Enterprises have embraced hybrid networks.
The expansion of SD-WAN, the benefits of having local internet breakouts for cloud services, and the evolution of network security tools have led more enterprises to employ multiple underlay products.
It’s been almost a decade since SD-WAN burst onto the scene, and the service is undeniably a critical component of today’s enterprise WAN.
The core benefits associated with SD-WAN technology are consistent across all provider offerings—reduced cost and network complexity, ease of upgrades and policy changes, increased flexibility and network performance, and increased visibility into application performance.
But a dizzying array of SD-WAN service options still remain in the market.
Providers continue to add new service and security features to distinguish themselves in a crowded marketplace. And this multitude of different service options are reflected in the range of reported prices in the market.
Luckily, there is a light at the end of the tunnel: TeleGeography’s 2024 SD-WAN Vendor Guide.
The geographic coverage of carriers’ enterprise network services varies significantly.
Not every carrier connects to every city in their customers’ networks, and not all services are available everywhere.
When narrowing down the universe of potential suppliers, enterprises must first consider how their geographic requirements overlap a potential service provider’s physical network. They then must determine if the specific data services they require are enabled at each of the service providers’ PoPs.
The WAN Services Coverage analysis—one section of our Cloud and WAN Research—examines carrier network connectivity and service availability from a geographic perspective.

Last week, we wrapped up a five-part podcast special that literally explains how the internet works.
This series describes precisely how data moves around the world, covering the basics of internet, transport networks, data centers, the cloud, and WAN along the way.
At the end of each episode, I thought it would be fun to relate what we talked about to a real world example: the lifecycle of a YouTube video.
To paint the full picture, I've compiled each piece of the story here. Keep reading to find out how a video goes from one camera to millions of screens around the world.
“Enterprises have shifted connectivity to the internet, mostly with DIA. This changes the security environment away from private MPLS to the best-efforts public internet.”
Last week, Senior Manager of Enterprise Research Greg Bryan joined Ciena's Brian Lavallée for a live webinar all about submarine cables and security.
For his part, Greg described how the enterprise network has shifted in the last few years, how carriers and enterprises have responded to these changes, and why geography matters in network security.
This week on TeleGeography Explains the Internet, we welcome SmartCIC CEO Toby Forman to the show.
Today’s TeleGeography Explains the Internet guest comes to the security world with a deep background in cloud and networks.
Joe DePalo is Chief Platform Officer at Netskope, and the ideal person to help us understand how and why location matters in network security.
Why am I getting ads for this toothpaste? How could my devices possibly know I'm in the market for a new tube? Did they hear me mutter something about running low? Do they know I jotted it down on our grocery list?
Today on TeleGeography Explains the Internet, we're asking the big questions about mobile advertising.
