Managed Network Services
Connecting people, places, and performance

A slow, unreliable or poorly secured network stops everything. We manage your connectivity end to end (across WAN, LAN and Wi-Fi) so your sites, users and applications stay connected, secure and performing, without your team carrying the burden of keeping them that way.
Trusted to manage enterprise connectivity across regulated sectors
Connectivity that keeps your business moving. Quietly, securely and at scale.
Network issues rarely stay local - slow connections, misconfigured access points and dropped calls quickly hit productivity and client experience. Our Managed Network Services keep SD-WAN, LAN, Wi-Fi, Teams voice and ZTNA stable, secure and connected.
SD-WAN
Smarter connectivity across every site
Traditional WAN wasn't built for multi-site, cloud-connected, hybrid work. SD-WAN replaces rigid connectivity with software-defined networking that adapts to demand - better performance, lower cost, a network that scales with you.
- Dynamic routing for optimal application performance
- Centralised visibility and management across all sites
- Built-in security and encryption
- Support for hybrid and multi-cloud connectivity
LAN & WiFi
Reliable, secure connectivity across every floor, site and device
Your local network is the foundation your people work from daily. We design, deploy and manage enterprise-grade LAN and Wi-Fi across your sites, keeping every device connected, secure, and Teams-ready.
- Enterprise-grade wired and wireless networking
- WiFi coverage design and optimisation
- Access control and user authentication
- 24/7 monitoring and support
Secure Web Gateways & Zero Trust
Perimeter security and identity-aware access, continuously managed
Traditional network security assumes everything inside the perimeter can be trusted - that no longer holds. Our Secure Web Gateway and Zero Trust Network Access, on Cloudflare One, protects at the edge with identity-verified, policy-driven access.
- Web content filtering and threat blocking
- Traffic inspection and policy enforcement
- Secure access across cloud and on-premise environments
- Identity-aware, policy-driven access controls
- Integrated with broader network security controls

Our continued partnership with OneAdvanced enables us to maintain secure and reliable operations while driving innovation and efficiency across our organisation.
