Best SD-WAN Solutions and Providers in 2022

Software-defined wide area networks (SD-WANs) increase the connectivity, flexibility, and scale of enterprise networks, removing much of the physical and manual limitations on administrators. 

Enterprises must quickly and securely transport data between distributed data centers, offices, and cloud applications. SD-WANs are a software-managed method of efficiently connecting an entire enterprise to the places and data they need to operate.

See below to learn about SD-WAN technology and the top SD-WAN providers in the market: 

Best SD-WAN Solutions and Providers

SD-WAN features 

Software-defined WAN solutions often include the following features:

  • Dynamic application traffic adjustment: Software-defined networks provide methods for application traffic to be transferred to another network link if the path they’re initially traveling has technical difficulties. Application performance is less likely to be negatively affected when the software can dynamically shift packets to a working section of the network. 
  • Built-in security tools: Most SD-WAN vendors provide a few security features, such as antivirus software or access control; some enterprise cybersecurity providers also have SD-WAN or integrated secure access service edge (SASE) solutions with additional security features. 
  • Analytics: The ability to visualize data from all regions of the network, including edge offices, in one platform centralizes enterprise traffic analysis. Some vendors also offer more advanced analytics for network data, like threat intelligence-specific features. 
  • Integration with public cloud providers: For enterprises, connecting cloud storage and workloads to their corporate software-defined network improves flexibility and the ease of moving application data across the network.

SD-WAN benefits

SD-WAN benefits for enterprises include:

  • Improved connectivity for remote workforces: Enterprises that have national or international offices and data centers or colocation centers can link all their locations together with a software-defined WAN, able to communicate between all branches. 
  • Ability to use multiple network protocols: SD-WANs allow enterprises to use legacy network technologies, like MPLS, alongside broadband and Ethernet. Some SD-WANs also include 4G, LTE, or 5G network connectivity for mobile device networking. 
  • Increased network security: Tools such as firewalls, microsegmentation, and network access controls, which are included in some SD-WANs, tighten enterprise network security, decreasing the chances of a breach.
  • Decreased time requirements for administrators: Because the network is software-defined, admins can more easily set policies, rather than having to go to each branch or data center and manually configure a networking appliance.

SD-WAN use cases

“​​We have roughly 160 sites worldwide consisting of manufacturing plants, warehouses, and office space. We ran proof-of-concept trials with several SD-WAN vendors, and Prisma proved the best fit for our network. The analytics alone are very impressive, but combine that with ease of migration, scalability, and improved MTR and this became an easy decision. The sales and technical support along the way has been exceptional.” -network services employee, review of Prisma SD-WAN at Gartner Peer Insights 

“Implementation was fantastic and the CATO solution did everything as advertised. We eliminated edge routers as well as on prem NG firewalls, web content filtering and VPN hardware. This allowed us to finally move away from backhauling Internet traffic, decentralize connectivity while still maintaining a single pane of glass to all network traffic, edge security, antivirus\malware, web filtering and VPN. Our 27 location network is nearly bullet proof now. CATO enabled us to quickly transition to remote work and also bring a new location online in Mexico during the COVID crisis.” -IT director, review of Cato SASE Cloud at Gartner Peer Insights 

“Overall, it has been a huge success migrating from a legacy traditional network to SDWAN. After the initial design and architecture was ironed out, adding additional sites has been very quick and painless. Dynamic failover to cellular backup is a true gamechanger… DMPO feature works well in mitigating latency/packet loss on WAN circuits.” -senior principal network architect, review of VMware SD-WAN at Gartner Peer Insights

What to look for in an SD-WAN solution

To choose an SD-WAN solution, consider the following questions:

  • Do you need heavy security features in your solution? Examples of businesses that might want stronger security tools built into their SD-WAN include medical and financial services companies. 
  • How many protocols does the SD-WAN support? If your business is still planning to use legacy technology, you’ll need an SD-WAN solution that supports those older protocols, like MPLS.
  • Does the SD-WAN solution offer 4G, LTE, or 5G connectivity? If your enterprise has a heavily mobile workforce, speak with the SD-WAN provider to determine which cellular technology they support. 
  • Does your business need advanced analytics? Larger enterprises may want an SD-WAN solution with heavy data analytics features.
