Managed Secure SD-WAN

SD-WAN (Software-Defined Wide Area Network) is a modern approach to managing and securing connectivity across sites, data centres, cloud platforms and remote users. Built on Fortinet’s Secure SD-WAN architecture, the solution converges SD-WAN, next-generation firewall and advanced routing into a single, unified platform. Traffic is intelligently directed across MPLS, broadband and 4G/5G links in real time, delivering high-performance, resilient connectivity with embedded security and a structured pathway toward Unified SASE.

Why Choose Britannic For SD-WAN

With over 40 years of experience delivering secure connectivity, Britannic understands not only how to deploy SD-WAN, but how it reshapes wider WAN strategy. Organisations have been supported through the evolution from MPLS to cloud-first networking, where success depends on careful design, structured transition and ongoing optimisation rather than simple hardware installation. The approach is consultative and long-term, aligning network architecture with security posture, cloud adoption and operational objectives so WAN environments remain resilient, adaptable and built to support long-term growth.

SD-WAN Features And Capabilities

Unified Secure SD-WAN Platform

Built on Fortinet technology, the platform combines SD-WAN, next-generation firewall (NGFW), advanced routing and Zero Trust Network Access (ZTNA) within a single operating system. Networking and security functions operate together at the WAN edge rather than as separate appliances.

Dynamic Application-Aware Routing

Traffic is monitored in real time using metrics such as latency, jitter, packet loss and bandwidth utilisation. Routing decisions are made automatically based on application type and predefined business policies.

Multi-Transport Connectivity

Supports MPLS, broadband, direct internet access and 4G/5G connections within the same architecture. Multiple links can operate concurrently under centralised control.

ASIC-Accelerated Performance

FortiGate appliances utilise dedicated ASIC hardware to accelerate SD-WAN overlay tunnels and application inspection. This allows routing and security processing to operate at high throughput.

Integrated Next-Generation Firewall

Embedded firewall functionality provides traffic inspection, encrypted VPN connectivity and advanced threat protection. Security policies are enforced consistently across branches, data centres and remote users.

Centralised Management And Policy Control

A single management interface provides configuration, monitoring and policy orchestration across the entire estate. Changes can be deployed centrally without device-by-device configuration.

High Availability And Automatic Failover

Supports dual and diverse circuits at each site. Traffic is automatically re-routed if performance thresholds are exceeded or a link becomes unavailable.

Digital Experience Monitoring

Provides visibility into application performance and user experience across the network. Performance data supports diagnostics and operational monitoring.

24/7 Monitoring And Managed Service

Devices and connectivity are monitored continuously by Britannic’s Network Operations Centre. Availability, bandwidth and performance metrics are tracked through real-time dashboards and alerting systems.

SASE-Ready Architecture

The platform supports extension into a Unified SASE model, enabling secure connectivity for remote users, cloud workloads and distributed environments within the same framework.

Business Benefits Of SD-WAN

  • Improves application performance by dynamically routing traffic based on real-time network conditions, ensuring critical services remain stable and responsive.
  • Increases network resilience through automatic failover and multi-link connectivity, reducing the risk of downtime across sites.
  • Reduces operational complexity by consolidating networking and security functions into a single managed platform.
  • Lowers dependency on costly dedicated circuits by enabling flexible use of broadband and cellular connectivity alongside MPLS.
  • Enhances visibility across the entire WAN, providing deeper insight into application usage, performance trends and link health.
  • Strengthens security posture by embedding firewalling, encryption and threat protection directly at the network edge.
  • Accelerates site deployment and change management through centralised configuration and policy orchestration.
  • Supports hybrid working and cloud adoption by optimising connectivity to SaaS, UCaaS and cloud environments.
  • Enables long-term scalability as new sites, users and applications are added without redesigning the core architecture.
  • Aligns network performance with business priorities, ensuring bandwidth and routing decisions reflect operational needs.

What Is The Difference Between MPLS WAN And SD-WAN?

MPLS remains a trusted and predictable connectivity solution, particularly where guaranteed performance and private routing are essential.

SD-WAN introduces flexibility, centralised control and application-aware intelligence, making it well suited to hybrid, cloud-driven and multi-site environments.

In many cases, organisations deploy both, combining MPLS reliability with SD-WAN’s dynamic control and optimisation.

Category
MPLS
SD-WAN
Network Type Dedicated, carrier-managed private network Software-defined overlay across multiple transport types
Connectivity Options Primarily dedicated MPLS circuits MPLS, broadband, DIA, 4G/5G used together
Traffic Routing Predefined paths using labelled packet forwarding Dynamic routing based on real-time performance metrics
Application Prioritisation Strong QoS controls within the private network Application-aware routing with policy-based traffic steering
Performance Predictability Highly predictable due to dedicated circuits Optimised dynamically based on link conditions
Scalability Circuit upgrades required to increase bandwidth New links can be added without major infrastructure changes
Cloud Connectivity Typically routes via central data centre Direct-to-cloud routing supported
Security Model Relies on private network isolation; security often added separately Integrated next-generation firewall and encrypted overlay
Management Managed per circuit, often provider-controlled Centralised, software-based management across all sites
Cost Structure Higher per-megabit cost for dedicated bandwidth Flexible cost model using mixed transport options
