SD-WAN in the UK
Software-defined networking that routes every application over the best available link, for faster, more resilient multi-site connectivity. Designed and managed by Sequential Networks.
APPLICATION-AWARE ROUTING · MULTI-LINK FAILOVER · OWN UK NETWORK · ISO 27001 & 9001 · UK SUPPORT
SD-WAN gives your multi-site business one intelligent, centrally managed network that automatically sends each application over the best available connection, whether that is a leased line, broadband or 4G/5G. Sequential designs, deploys and fully manages it on top of our own UK network, so you get the agility and resilience of SD-WAN with the performance of infrastructure we control.
What is SD-WAN?
SD-WAN (software-defined wide-area networking) separates your network’s control from the underlying hardware, so a central controller decides in real time how traffic flows across your links. Instead of backhauling everything through one circuit, it routes each application, cloud, voice or file transfer over the path that suits it best.
The result is a WAN that is cheaper and more flexible than traditional MPLS, more resilient thanks to multiple links, and far easier to manage from a single cloud portal.
Why choose Sequential Networks for SD-WAN
Plenty of providers resell an SD-WAN overlay. We run the network underneath it, which is where the real performance comes from:
- Our own UK network and data centres: SD-WAN over infrastructure we operate, not just an overlay on someone else’s links.
- Pairs perfectly with our leased lines: combine SD-WAN with a Sequential leased line for a guaranteed underlay and intelligent routing on top.
- Lower cost than MPLS: use cheaper, mixed transport (fibre, broadband, 4G/5G) without giving up resilience.
- Fully managed, centrally controlled: one cloud portal, real-time visibility, and we handle the design, rollout and day-to-day.
- ISO 27001 and ISO 9001 certified (UKAS): security and quality independently audited.
- 24/7 UK support: proper engineers whenever you need them.
SD-WAN vs MPLS
| MPLS | SD-WAN | |
|---|---|---|
| Transport | Dedicated circuits only | Any link: fibre, broadband, 4G/5G |
| Cost | Higher | Lower, uses mixed links |
| Resilience | Typically single path | Multiple links, automatic failover |
| Cloud & SaaS | Backhauled via the core | Direct, application-aware routing |
| Deployment | Slower to roll out | Rapid, zero-touch at each site |
| Control | Provider-managed changes | Centralised portal, real-time |
Not sure which fits? We provide both and can advise, or combine them so a leased line underpins your most important sites.

Who it’s for
SD-WAN suits any business running more than one site or leaning heavily on cloud:
- Multi-site organisations wanting one consistent, resilient network.
- Cloud and SaaS-heavy teams needing direct, prioritised access.
- Retail, hospitality and field sites where broadband or 4G is the practical link.
- Anyone looking to cut MPLS costs without losing resilience.
One joined-up network
SD-WAN is strongest as part of a joined-up network. Because we run the whole stack, we can build around it:
- Underpin it with a leased line for a guaranteed path
- Compare with MPLS for a fully private multi-site network
- Add hosted VoIP and cloud on the same managed network
- IT support and procurement
One supplier, one bill, one team across connectivity, cloud and colocation.
Frequently asked questions
What is SD-WAN?
SD-WAN is software-defined wide-area networking that routes each application over the best available link across your sites, all centrally managed from one cloud portal.
How is SD-WAN different from MPLS?
SD-WAN uses any mix of links (fibre, broadband, 4G/5G), is lower cost and more resilient with automatic failover, and routes cloud traffic directly. MPLS uses dedicated circuits with very predictable performance. We offer both and can advise or combine them.
Is it fully managed?
Yes. We design, deploy and manage your SD-WAN, with a central portal for real-time visibility and 24/7 UK support.
Can I use my existing connections?
Yes. SD-WAN works over your choice of links, and pairs best with a Sequential leased line as the underlay for your key sites.
Is it secure?
Yes. Traffic between your sites runs over encrypted tunnels, and we are ISO 27001 certified.
How quickly can new sites be added?
SD-WAN supports zero-touch deployment, so new sites can be brought online quickly with minimal on-site setup.
