FAQs

Answers to common questions about managed network services.

Managed network services involve outsourcing the monitoring, management, optimisation and security of network infrastructure to a specialist provider.

A managed network services provider is responsible for maintaining the performance, availability and resilience of critical networking environments, including WAN, LAN, Wi-Fi, SD-WAN and cloud connectivity. Services typically include 24/7 network monitoring, incident and problem management, network security, performance optimisation and strategic support delivered through a Network Operations Centre (NOC).

By partnering with a managed network services provider, organisations can gain access to specialist networking expertise, improve operational efficiency and ensure their network infrastructure remains secure, scalable and aligned to business objectives.

Managed network services help organisations improve network performance, strengthen security and reduce the operational burden on internal IT teams.

By providing proactive monitoring, rapid incident response and access to experienced network specialists, managed services help minimise downtime and maintain the availability of business-critical applications and services. Organisations also benefit from improved visibility, predictable operational costs and support for modern technologies such as SD-WAN, cloud networking, network automation and Zero Trust security frameworks.

For organisations adopting Microsoft Azure, AWS, hybrid cloud or hybrid working models, managed network services provide the expertise and operational support needed to maintain secure, reliable and high-performing connectivity across the business.

Yes, most managed network services include 24/7 network monitoring as a core service.

Continuous monitoring enables organisations to identify and resolve issues before they impact users, applications or business operations. A dedicated Network Operations Centre (NOC) monitors network performance, availability, capacity and security, providing proactive alerting, incident management and service assurance.

This approach helps reduce downtime, improve user experience and maintain the performance of business-critical network infrastructure.

A Network Operations Centre (NOC) is a dedicated team responsible for monitoring, managing and supporting network infrastructure.

Operating 24/7, a NOC provides proactive monitoring, incident response, fault management and performance optimisation across enterprise networks. Network engineers use specialised tools to identify and resolve issues before they impact users or business services.

A NOC helps organisations improve network availability, reduce downtime and maintain service levels across critical infrastructure.

Managed network services improve network security through continuous monitoring, policy management and proactive threat mitigation.

Many providers support modern security frameworks such as Zero Trust and Secure Access Service Edge (SASE), helping organisations secure users, devices and applications across distributed environments. Services often include firewall management, network access controls, vulnerability monitoring and security reporting.

By combining network management and security operations, organisations can strengthen resilience, reduce risk and improve visibility across their network infrastructure.

Yes, managed network services are designed to support cloud, hybrid and multi-cloud environments.
As organisations adopt platforms such as Microsoft Azure, Amazon Web Services (AWS) and Microsoft 365, network performance becomes increasingly important. Managed network services help optimise connectivity between users, applications, cloud platforms and on-premises infrastructure while maintaining security and reliability.

This ensures organisations can support hybrid working, cloud transformation and business growth without compromising user experience or operational performance.

WAN, LAN and SD-WAN are different types of network architecture that serve distinct purposes.
A Local Area Network (LAN) connects users, devices and applications within a single location, such as an office or campus. A Wide Area Network (WAN) connects multiple locations over larger geographic areas using technologies such as MPLS and internet connectivity.

Software-Defined Wide Area Networking (SD-WAN) is a modern approach to WAN management that improves application performance, simplifies network operations and provides greater visibility and control across distributed environments.

Yes, many managed network service providers use network automation to improve efficiency, consistency and performance.

Network automation reduces manual administration by automating routine tasks such as configuration management, policy deployment, device provisioning and compliance checks. Combined with observability platforms, analytics and AIOps technologies, automation can accelerate issue resolution and improve operational visibility.

This enables organisations to scale network operations more effectively while reducing operational complexity and risk.

Managed network services can support a wide range of networking, cloud and security technologies.
Depending on requirements, organisations may use solutions from vendors such as Cisco, Cisco Meraki, Fortinet, Palo Alto Networks, Juniper Networks and HPE Aruba Networking. Services can also support cloud platforms including Microsoft Azure, AWS and Microsoft 365.

A managed service provider should be able to recommend, deploy and support the technologies that best align with an organisation’s operational, security and business objectives.

Yes, managed network services are particularly valuable for organisations operating across multiple locations.

By centrally managing WAN, SD-WAN, LAN, Wi-Fi and cloud connectivity, organisations can maintain consistent performance, security and visibility across offices, branches, retail locations and operational sites. Managed services also simplify network management by providing a single point of accountability for monitoring, support and optimisation.

This helps multi-site organisations improve user experience, support hybrid working and scale network infrastructure more efficiently.

The cost of managed network services in the UK depends on the size, complexity and support requirements of your network.

Pricing is typically influenced by factors such as the number of sites, users and network devices, the complexity of your LAN, WAN or SD-WAN environment, cloud connectivity requirements, security needs and the level of monitoring and support required. Organisations with multi-site networks, Microsoft Azure or AWS connectivity, firewall management, 24/7 Network Operations Centre (NOC) support or strict Service Level Agreements (SLAs) will usually require a more tailored managed service.

A managed network services provider will normally assess your existing infrastructure, business-critical applications, security requirements and future growth plans before recommending the right service model. This ensures the cost reflects the level of resilience, performance, security and operational support your organisation needs.
