Modernise your network
Bring legacy hardware to life.
For many organisations the network has quietly become a constraint the business has
learned to work around: too fragile to change, too important to leave alone. We modernise it
in place, in controlled waves, into an estate that is resilient, adaptable and evidenced as it
runs.
When the network was built
for a different way of working
Few network problems announce themselves. They show up as the workaround everyone has stopped noticing, the change nobody wants to make first, the transformation that quietly stalls.
Most enterprise networks were designed for a different era. Static routing. Single broadband or MPLS circuits per site. Applications hosted on-premise. Users in offices. Traffic that mostly stayed inside the network.
The way businesses actually work has changed. Microsoft 365, Teams, Zoom, VDI, line-of-business applications in the cloud. Hybrid working. Customer-facing operations that can’t tolerate downtime. Real-time traffic that demands path quality, not just bandwidth.
Most networks haven’t kept pace.
A constraint the business
has quietly accepted
Left alone, that drag compounds: slower projects, workarounds that harden into dependencies, and a network that quietly sets the ceiling on what the business can do next.
Teams calls drop in branches during busy periods. The VPN is slow. A site goes dark for three hours and the incident log says “ISP fault” with no further analysis. Someone mentions that application performance at the distribution centre has “always been a bit like that.” Change requests take weeks to turn around. Nobody knows what’s happening across the estate without phoning the helpdesk.
By the time the network is named as the problem, it’s already costing the business in lost productivity, missed cloud transformation outcomes, and customer-facing disruption that doesn’t show up in the IT budget.
That accumulating gap between how the network is meant to run and how it actually runs is governance debt, and modernisation is how it gets repaid.
Where modernisation matters
Growing or consolidating
Mergers, acquisitions, expansion, or office consolidation creates a network that wasn’t designed for the new footprint. A careful, staged approach to modernising the network can be the difference between a broader programme of work succeeding at pace, or grinding to a halt.
Exiting legacy MPLS
A renewal cycle, cost review, or consolidation programme creates an opportunity to move away from expensive, inflexible MPLS and multiple connectivity contracts. Secure SD-WAN can replace the rigid single-path private circuit model with a multi-path, application-aware managed service.
Optimising infrastructure
A cloud migration, digital transformation initiative, or a hybrid working rollout exposes the network as the bottleneck. The transformation can’t deliver until the network underneath it does.
AI traffic
AI-enabled applications create new data flows between cloud and on-premise systems, at volumes and sensitivity the existing design did not anticipate. The path needs capacity, inspection and a record of what moved.
"Too fragile to touch" is a design problem,
not a permanent condition.
Nobody modernises a critical estate in one move. It is done in waves, smallest complete boundary first, with the old and the new running under one operating model so nothing is stranded mid-transition.
Baseline
outcomes
Document what is there: circuits, routing, dependencies and the workarounds that have hardened into design. Most estates have at least one thing nobody expected.
Pick the
first wave
One site group, one application path or one contract renewal. Small enough to prove the model within a few weeks, real enough that the result is not theoretical or easily dismissed.
Run old and new
together
One platform spanning the old estate and the new, so nothing is ever half-managed, nothing is left orphaned in the middle of a long migration and there is always a clear route back.
Prove it,
then repeat
Acceptance criteria, rollback triggers, support routes and the evidence the new design should produce, all agreed and written down before the first wave starts rather than after it.
The first step towards
network modernisation
Managed
SD-WAN
Managed SD-WAN for multi-site estates and critical users. Resilient connectivity, application-aware traffic management, standardised design, and continuous monitoring. Options for rapid deployment, extreme resilience for critical sites, security attach, and enhanced observability.
How we can get you connected
Secure Internet
Access
For inspected, policy-controlled internet egress across all sites, consistently applied.
Data Centre
Interconnect
For high-speed dedicated connectivity between data centres and the rest of the network.
For services people depend on.
We are built for consequence, trusted by organisations responsible for national security, frontline healthcare, emergency response and public trust.
Common questions
about network modernisation
Is our network actually holding the business back?
When a site move or an application launch waits weeks on change requests, the network has become the constraint. Modernisation earns its place when the network is deciding how fast everything else can move.
Do I have to replace everything at once?
Modernising rarely means overhauling the whole network. It works best incrementally: the parts under most strain first, the rest as contracts and circuits allow, with one consistent platform across old and new so nothing is stranded mid-transition.
Can SD-WAN replace MPLS for regulated industries?
Yes, in most cases. Managed SD-WAN can replace MPLS for regulated organisations including NHS, government, financial services and other audited environments, provided the service is delivered with the security, segmentation and reporting the regulator requires. Cloud Gateway delivers SD-WAN with managed firewall, secure internet access and, where required, compliant connectivity to HSCN or PSN under the same operating model.
Should we keep any of our MPLS?
Sometimes. MPLS still suits a few predictable, high-assurance links, but for most estates it is now the expensive, inflexible part. The question is which links genuinely need it, not whether to keep it wholesale.
Connect. Protect. Observe. Operated as one.
