SD-WAN Solutions for UK SMEs & Multi-Site Businesses

SD-WAN replaces MPLS — or augments your existing connections — with intelligent, software-defined routing that sends traffic directly to its destination across the best available path. Sentinel SecureTech designs, deploys, and manages SD-WAN solutions for UK SMEs and multi-site businesses. We work alongside your leased lines, business broadband, and backup connectivity — or supply new circuits as part of a complete SD-WAN solution.

Is MPLS Costing Your Business More Than It Should?

MPLS (Multiprotocol Label Switching) was the enterprise WAN standard for decades — but for UK SMEs, it is now expensive, inflexible, and poorly suited to cloud-first working. MPLS routes all traffic through a central hub before it reaches the internet — meaning a Teams video call from your Wolverhampton site travels to your Birmingham head office and back before reaching Microsoft’s servers. Every cloud application suffers the same inefficiency.

Application-Aware Traffic Routing

SD-WAN identifies and prioritises traffic by application — automatically. Microsoft Teams, VoIP calls, Salesforce, and your line-of-business applications get priority routing across your best available connection. Low-priority traffic — software updates, backup jobs, general browsing — uses remaining capacity without impacting business-critical applications.

Automatic Failover — Seconds, Not Minutes

If one of your WAN connections develops a fault — whether a leased line, FTTP, or 4G circuit — SD-WAN detects the failure and re-routes traffic automatically within seconds. No manual intervention. No outage visible to your team. Your applications keep running on the remaining healthy connections while the fault is resolved.

Centralised Management — All Sites, One Dashboard

Whether you have two sites or twenty, SD-WAN provides centralised visibility and management of your entire WAN from a single dashboard. Security policies, routing rules, QoS settings, and application priorities are configured once and applied consistently across all your locations — no individual site configuration required.

Optimised for Cloud-First Businesses

SD-WAN breaks out cloud-bound traffic — Microsoft 365, Azure, Salesforce, Google Workspace — directly to the internet at each site, rather than backhauling it through a central hub. This dramatically improves application performance and reduces the latency that kills the experience of cloud-hosted tools.

MPLS Replacement or Hybrid SD-WAN

We deliver both full MPLS replacement and hybrid SD-WAN deployments — where SD-WAN overlays your existing MPLS network and manages traffic intelligently across both. Full replacement is typically the right choice for cost reduction. Hybrid is appropriate where specific traffic must traverse private circuits for compliance or security reasons.

Which UK Businesses Need SD-WAN?

SD-WAN is the right solution for your business if:

You have two or more offices or sites connected over WAN
You are paying for MPLS and questioning whether you are getting value from it
Your cloud applications — Teams, Salesforce, Microsoft 365 — perform inconsistently across sites
You need automatic failover without manual intervention when a circuit fails
You want centralised visibility and control of your network across all locations
You are opening new sites and need a scalable, cost-effective WAN solution

Why UK SMEs Choose Sentinel SecureTech for SD-WAN

Our SD-WAN service is delivered alongside leased lines, backup connectivity, and network management — meaning your SD-WAN sits within a fully managed network environment, not as a standalone product with a separate support team

Vendor-Agnostic — We Choose What Is Right for You

We work with all leading SD-WAN vendors — Cisco Meraki, Fortinet, VMware, Palo Alto, and others. We recommend the platform that best fits your environment, budget, and operational requirements — not the one that pays us the highest margin.

We Supply the Circuits Too

Most SD-WAN providers expect you to bring your own WAN circuits. We supply and manage the underlying connectivity — leased lines, FTTP, and 4G failover — as part of a complete solution.

Fixed Monthly Pricing

SD-WAN managed services are priced on a fixed monthly basis. One cost covers the platform, management, monitoring, and support across all your sites.

How Does SD-WAN Deployment Work?

WAN Assessment

We assess your current WAN — topology, circuits, applications, and costs — and model what SD-WAN would deliver in terms of performance improvement and cost saving. Written deliverable. No obligation.

Solution Design

We design your SD-WAN architecture — platform selection, circuit requirements, routing policies, QoS configuration, and failover design. We present and agree the design with you before any work begins.

Staged Deployment

We deploy SD-WAN site by site — starting with your head office or highest-priority location, validating performance, then rolling out to remaining sites. Existing connectivity is maintained throughout.

Ongoing Management

We monitor and manage your SD-WAN environment on an ongoing basis — adjusting routing policies, responding to performance alerts, managing circuit faults, and providing monthly WAN performance reports.

Your Questions About SD-WAN for UK SMEs — Answered

What is SD-WAN and how is it different from MPLS?

SD-WAN is software-defined wide area networking — it manages traffic intelligently across multiple connections.

MPLS routes all traffic over private circuits through a central hub — expensive and not optimised for cloud applications. SD-WAN routes traffic dynamically across the best available path — leased line, broadband, or 4G — with application-aware prioritisation and automatic failover. Most UK SMEs save significant cost moving from MPLS to SD-WAN without any reduction in reliability.

How much does SD-WAN cost for a UK SME?

SD-WAN for UK SMEs is typically priced on a fixed monthly per-site basis.

Cost depends on the number of sites, the SD-WAN platform selected, and whether we are also supplying underlying circuits. We provide a free WAN assessment and written quote before any commitment. Most businesses moving from MPLS find SD-WAN delivers better performance at lower total cost.

Can SD-WAN work with our existing internet connections?

Yes — SD-WAN is designed to work with mixed connection types.

We can overlay SD-WAN across your existing leased lines, FTTP connections, and 4G circuits. We can also supply new circuits as part of the solution. SD-WAN’s value comes from managing multiple connections intelligently — the more diverse your underlying circuits, the more resilient the result.

How long does SD-WAN deployment take?

A typical SD-WAN deployment for a two to five site UK business takes four to eight weeks.

Timeline depends on site count, any new circuit requirements, and the complexity of your application routing policies. We deploy site by site to minimise disruption — your existing connectivity continues to work throughout the rollout.

Does SD-WAN replace our need for a leased line?

No — SD-WAN manages your connections. A leased line is one of those connections.

SD-WAN and leased lines are complementary, not alternatives. SD-WAN adds intelligent management, failover, and application routing across your WAN — including over your leased line. For high-demand sites, we recommend a leased line as the primary circuit, with SD-WAN managing it alongside secondary broadband or 4G failover.
