Outcomes

  • Average latency reduced by 35–50% between sites
  • 99.95% measured availability with dual‑path failover
  • Zero‑touch provisioning for branch sites
  • Improved security posture with micro‑segmentation

The challenge

The client faced traffic congestion on a single MPLS link and an over‑permissive flat network, leading to poor application performance and elevated risk.

Objectives

  • Introduce redundant connectivity with intelligent path selection
  • Segment critical systems from user and OT networks
  • Improve observability and alerting
  • Minimise downtime during migration

How we delivered

Approach

  • Design hosted SD‑WAN overlay with DIA and LTE failover
  • Dual‑ISP circuits per HQ with BGP and policy‑based routing
  • VLAN segmentation and firewall policies by zone
  • Runbooks and change windows aligned with operations
