SD-WAN, explained
What is SD-WAN?
Your connections carry the traffic.
SD-WAN helps choose the route.
SD-WAN means software-defined wide area networking. It adds centrally managed policies over the physical internet and network connections at your sites, helping decide how traffic moves between locations and applications.
A voice call, a cloud application and a large backup do not need the same treatment. The design can use application priorities and supported link-health measurements to choose suitable paths, while giving administrators a more consistent view.
See the bigger picture →Built around the work you do
Less guesswork.
More direction.
Make routing, visibility and security follow the way your organisation actually works.
Blend your connections
Use suitable broadband, Ethernet and mobile access in one design. Each site can have a different mix of physical links.
Central visibility
Bring available performance information and policies together, with clear administrator roles and a defined change process.
Security in the design
Review segmentation, firewalling and internet breakout alongside routing. Included controls and licences depend on the platform.
Repeatable deployment
Create a consistent site standard. Supported remote or zero-touch provisioning can simplify rollout where included.
More purposeful failover
Agree when traffic should use an alternative path and which applications take priority when spare capacity is limited.
Service availability, equipment, features, licences and support scope are confirmed in your proposal. Optional services are priced and agreed separately.

Make an informed choice
What changes behind the scenes?
The underlay
These are the real connections at each site: broadband, leased lines or mobile access. Their capacity and physical availability still matter.
The overlay
A logical network links supported edge devices, commonly using protected tunnels. Routing and security boundaries follow the agreed design.
The policy
Define priorities, link-health thresholds and fallback behaviour. Test these against real applications before rolling out across the estate.
Continuity, considered
Move your network
forward in stages.
SD-WAN can support a phased move from an existing WAN or MPLS environment. The useful starting point is your application paths, addressing and security requirements.
Plan your setup ↗Start with a representative pilot
Choose a site that reflects real traffic, working patterns and the links you intend to use.
Plan security with routing
Decide what breaks out locally, what stays between sites and what passes through central controls.
Measure the agreed outcome
Test application performance and failover, then review policies as the business changes.

SD-WAN,
answered.
Have a question about your site?
Start with the address and what you need.
Does SD-WAN replace our internet connections?
No. It uses physical access services and supported equipment. You still need enough capacity and a suitable continuity design at each site.
Can it replace MPLS?
A migration or mixed design may be possible. We review private application access, addressing, routing and security dependencies before recommending a phased approach.
Does every site need the same connection?
No. Sites can use different access types where the platform supports them. The choice depends on workload, availability and continuity needs.
Is security included?
The selected platform and package determine the controls. Your proposal should specify firewall, filtering, intrusion protection or separate security services where required.
Does failover mean calls never drop?
No. Session continuity depends on the platform, configuration and application. Switching paths can affect active calls, VPNs and public addresses; testing is essential.
Can Radian help manage it?
We can discuss a managed arrangement through delivery partners, including policy ownership, monitoring, support and how changes are authorised.
UK-wide service enquiries
SD-WAN across the UK.
For offices across the UK, document sites, applications and access connections before defining routing policy. SD-WAN can coordinate supported links, but coverage, capacity, security and ongoing management still need a site-by-site plan.
Based in Charlwood, we welcome enquiries nationwide, with a particular focus on Horley, Crawley, Gatwick, Surrey, Sussex and London. Delivery, availability and any site attendance are confirmed for your chosen service.
