10 Best SD-WAN Vendors & Solutions – Updated 2022!

An easy and affordable method of connecting the networks of a multi-site company is provided by SD-WANs. We investigate which SD-WAN technologies will enable the WANization of your LANs.

A WAN is not created when LANs connect to the internet to communicate. Even if they are spread out over a large area, all links in a WAN are private.

Best SD-WAN vendors:

  8. Cato SASE Cloud: A safe SD-WAN service from a company that controls a fast backbone and can direct your traffic through its own network. calls for an exclusive gateway on each site.
  9. Cisco Meraki SD-WAN: A Meraki gateway appliance-based SD-WAN service that is controlled by a cloud hub.
  10. Oracle SD-WAN: A cloud-based hub that needs an appliance running on each included LAN, whether it be physical or virtual. Services for a firewall can be put on.

Why use an SD-WAN?

It is exceedingly expensive and difficult to obtain permission to lay the cable over both public and private land and to purchase all of the cable needed to connect the two sites. Leasing a line from a telecom provider is one option. This tactic, nevertheless, is also expensive.

Despite the fact that the company managing the network does not own the physical media, this is referred to as a “overlay network” and it counts as a private line. This is how SD-WAN earned its name; it uses software to turn LANs that are connected to the internet into a WAN.

For SD-WANs to connect to the internet, a device is needed. The network’s gateway can be reached by routing all traffic intended for the internet through a server that is running the WAN-creating software. We refer to this as a virtual solution. The alternative is to purchase unique equipment that functions as a gateway and has SD-WAN software built right in.

SD-WANs and UCaaS

Businesses no longer need to purchase and maintain the software necessary to build an SD-WAN solution, as well as the hardware necessary to operate communications software or a specialized appliance. Officially known as “Unified Communications as a Service,” or UCaaS, a cloud-based SD-WAN technology.

A cutting-edge technology called UCaaS manages all routing for your company. All traffic is directed to the UCaaS server, which serves as a hub, from all of your sites. The cloud server’s SD-WAN software sends general internet traffic intended for other companies through a gateway and directs business traffic to the proper location.

More about SD-WAN Technology

The SD-WAN software enables the address space of all involved LANs to be unified, regardless of whether it is hosted on a computer, integrated into an appliance, or based on the cloud provider’s server. The WAN is made up of this.

The presence of the internet in the system violates the criteria for the definition of a private WAN because it is different address space. However, the SD-WAN bridge’s encapsulation techniques that address-related issues allow the network software to disregard the fundamental internet’s addressing requirements.

The best SD-WAN vendors

You can now choose between cloud services and on-site SD-WAN solutions in the form of hardware or software thanks to UCaaS. All of these choices are present in our listing of the top SD-WAN providers.



The major provider of server virtualization is VMWare. Because both virtualization and the software-defined WAN remap real resources by how the program displays them to the user, they are very comparable concepts. Therefore, it makes sense for VMWare to enter this industry.

2. Citrix SD-WAN

Citrix SD-WAN

The second-largest vendor of virtualization software worldwide is Citrix. Citrix and VMWare both have compelling economic and technical arguments for including SD-WANs in their product lines as a provider of virtual machines.

Set an SD-WAN strategy

Choose if you want to host the SD-WAN software, purchase dedicated hardware to deploy the WAN connections, or go with a cloud-based SD-WAN service as your first step in the SD-WAN buying process. As you can see from our list, we investigated each of the three deployment strategies and came up with a solution.

Your search gets much easier once you have a plan in place. That procedure ought to be accelerated by our list of the top SD-WAN providers.


What is an SD-WAN appliance?

SD-WAN equipment can take the place of a standard network router. It carries out all connection management for a whole LAN to connect to distant locations.

What is the difference between SD-WAN and MPLS?

A routing technique called Multiprotocol Label Switching (MLPS) chooses a neighbouring router to transfer data onto based on the label of its short link rather than by consulting a routing table. Since SD-WAN uses IP addresses, it is simpler to route traffic online. When gaining access to an endpoint on a remote network, the SD-WAN merely handles the address changes to make it appear as though it is a local network resident.

What are the weaknesses of SD-WAN?

Yes, SD-WANs have flaws. Compared to a conventional WAN system, they require more preparation, and some monitoring tools may not be able to interact with an SD-WAN service or device or correctly decipher the address space that it generates.

Which three business problems does SD-WAN address?

SD-WAN systems are not created equal. However, there are options to combine numerous services using the SD-WAN approach. Network security protection is another feature of a good SD-WAN solution. Its capacity to adjust speeds for various forms of site-to-site traffic is another benefit. Thirdly, all addressing concerns are resolved by remapping them within the SD-WAN, which makes it simple for SD-WANs to integrate new sites.

What layer does SD-WAN use?

According to the OSI stack numbering, Layer 2 and Layer 3 are where SD-WAN can function. Some professionals refer to SD-WAN Layer 2.5 technology to describe this duality.

Does SD-WAN replace a VPN?

A VPN creates a single connection over the internet and routes all traffic via it. Multiple connections are managed simultaneously by an SD-WAN. For each, it may employ a separate technology, such as a VPN.
