Think of a software-defined network (SDN) as the foundation for a software-defined wide area network (SD-WAN). SD-WAN uses software and a centralised cloud based controller to intelligently steer traffic across the WAN. SD-WAN handles traffic based on priority, quality of service and security requirements in accordance with business needs.
Unlike traditional WAN architecture, the SD-WAN model is designed to fully support applications hosted in on-premise data centers, public or private clouds and SaaS solutions such as, Office365 and Dropbox, while delivering the highest levels of application performance.

Flexgrid’s managed SD-WAN offering securely connects all sites and users to any application, whether hosted in the data center or in the cloud, across any network including broadband Internet services.

The Solution

Our SD-WAN solution is based on Juniper technology, delivering application insights and automation through Mist AI.

Our SD-WAN solution is delivered as a cloud service bringing automated operations and service levels to the WAN edge, and when used in conjunction with Juniper Mist wired and wireless devices, we can provide a single platform to manage both the LAN and the WAN as one.

Managed service

24x7 managed SD-WAN service from the UK

Mixed transport

Enables organisations to leverage any combination of public and private transport services (e.g. broadband Internet, 5G, etc.) to securely connect users to apps and each other

Traffic steering

Provides compelling features such as application-based intelligent traffic steering, optimal link selection, intelligent acceleration, and intelligent O&M

Application set

Circa 600 applications already in the controller

Zero touch provisioning

Adopts a zero touch provisioning approach to deploying new circuits

Cloud managed

Manage your entire WAN from anywhere

Connectivity options

Can use existing connectivity for rapid deployment or Flexgrid can provide the underlying circuits acting as a single service provider


Can be deployed at some sites retaining MPLS (for example) at others or deployed across the entire WAN


One simple license per device, irrespective of bandwidth usage on the router

Get Technical

SD-WAN applies the principles of software-defined networking (SDN) to a business WAN connection; separating the data plane and control plane of the network and abstracting it into a virtualised service.

The architecture of SD-WAN virtualises numerous components of a traditional legacy network (e.g. secure routing, application optimisation, quality of service) and centralises the network management via a cloud-based “orchestrator” which intelligently controls traffic flows across the corporate network.

Leveraging the powerful application identification engine and link quality detection engine, the SD-WAN solution can provide intelligent traffic steering based on the application priority, link quality, load balancing, and bandwidth utilisation.
