Multi-site networking

One network, every location

Runningonesiteiscomplicatedenough.Addoffices,stores,facilities,remoteteams,andcloudplatforms,andkeepingeverythingconnectedcanquicklybecomeafull-timejob.

Different locations may rely on different providers, connection types, and security policies. That can leave your IT team juggling suppliers, chasing faults and trying to understand why users at one site are having a completely different experience from everyone else.

We bring your locations together through one secure, coordinated network. From the underlying WAN and connectivity to SD-WAN, next-generation firewalls and ongoing management, we’ll design a solution around how your organisation works. Choose a fully managed service or retain agreed visibility and control through a co-managed model.

So wherever your people are, they can access the applications, services, and information they need - without the network getting in their way.

Bringing it all together

Build the right foundation, add intelligent control, and protect every location through one joined-up multi-site networking strategy.

SD-WAN

Smarter traffic. Better performance.

SD-WAN adds an intelligent software layer across your network. It monitors available connections and directs traffic along the most appropriate route, helping business-critical applications perform more consistently.

  • Application-aware routing for important services

  • Centralised control across sites and connections

  • Managed and co-managed service options

Wide Area Network (WAN)

Private connections for stable, fixed estates.

A traditional WAN connects geographically separate locations through a private network, commonly using MPLS. Site-to-site traffic can travel through Nasstar’s core network rather than relying on the public internet.

  • Private connections between fixed sites and central services

  • Primary and backup connections designed around business criticality

  • Secure internet access through a central managed firewall

Managed WAN

We manage the network. You move the business forward.

Our Managed WAN service gives you one team to design, deliver and manage the network from end to end. We’ll take care of the day-to-day complexity, helping your IT team spend less time chasing providers and more time focused on strategic priorities.

  • End-to-end service through one accountable provider

  • 24/7 proactive device and service monitoring

  • Managed firewall patching prioritised according to vulnerability severity

Next-generation firewalls

Protection that follows your network.

A next-generation managed firewall protects your network boundary while giving you greater visibility and control over the applications, users, and services moving through it. Nasstar can manage firewalls at a central internet breakout, in your data centre, or at selected edge locations.

  • Proactive monitoring of firewall availability and operational incidents

  • Security patching to service-defined times based on vulnerability severity

  • Application-aware policies, web controls, and network segmentation

A multi-site network should feel like one environment, not a collection of disconnected locations. That means choosing the right connectivity for each site, protecting internet access consistently, and giving IT teams a clear view of performance across the estate. Our managed and co-managed options let organisations choose how much control they retain while we handle the monitoring, patching, and operational support that keep the network running.

Why choose Nasstar?

From network design and connectivity sourcing to security, migration, and ongoing management, we take responsibility for the whole multi-site journey.

When different providers manage individual parts of the network, resolving an issue can mean multiple calls, tickets, and hand-offs. We’ll bring your connectivity, network infrastructure, and management together through one coordinated service. That means clearer ownership and less time spent working out who needs to fix what.

A head office, retail store, warehouse, and temporary location will not all need the same service. We work across a broad ecosystem of connectivity providers and technologies, helping us select each site’s connection based on availability, performance, resilience, and cost.

Connectivity and security can no longer be treated as separate decisions. We can combine SD-WAN, segmentation, and next-generation managed firewalls to protect internet access and apply more consistent policies across locations. Operational monitoring and severity-led patching help reduce the burden of keeping firewall infrastructure available and up to date.

Fully outsourcing your network can feel like losing valuable visibility and technical control. Our co-managed service lets you choose the dividing line. Some users may have read-only access, while authorised administrators can make agreed changes. Nasstar protects core management functions and remains available to guide or carry out more complex work alongside your team.

It’s hard to improve a network without understanding how it is performing. Centralised monitoring and reporting give you a clearer view of connections, devices, and applications across your estate. This helps identify recurring issues, emerging capacity constraints, and opportunities to optimise your investment.

New offices, acquisitions, hybrid working, and cloud adoption can all place new demands on your network. We’ll design an environment that can support additional locations, users, and technologies without requiring you to start again whenever the organisation changes.

Getting ready for the big switch-off

The retirement of the UK’s analogue phone network is about more than replacing traditional desk phones.

Alarms, payment terminals, entry systems, lift lines, and other equipment may still depend on legacy services. Your underlying connectivity may also need to be reviewed to make sure it can support IP voice and other digital replacements.

We’ll help you understand what could be affected, assess which services are available at each site, and build a practical route towards modern connectivity.

Prepare for the switch-off.

FAQs

01

Multi-site networking connects an organisation’s offices, stores, facilities, data centres, cloud platforms, and other locations through one coordinated network.

It allows people at different sites to access shared applications, systems, and data securely. A multi-site network may combine different connectivity services and technologies, including WAN, Managed WAN, SD-WAN, and next-generation firewalls.

The aim is to provide a consistent experience across the organisation while making the wider environment easier to secure, monitor, and manage.
