About Fulton Hogan

Fulton Hogan is one of New Zealand's largest and most respected infrastructure, roadworks and construction companies, operating across hundreds of sites and employing thousands of staff. With a significant footprint in regional and remote parts of the country, Fulton Hogan depends on reliable, secure communications infrastructure to support its internal operations and its joint venture partners.

The Challenge

The existing network infrastructure relied on a mix of disparate, legacy technologies – many of which were deployed on a per-region or per-subsidiary basis, leading to fragmentation, inconsistencies and blind spots in network management.
‍

Many Fulton Hogan sites were in areas with no fibre coverage, relying instead on legacy network services. Joint venture and subsidiary entities needed segmented access, creating further complexity around security and access control. Meanwhile, the lack of a consistent, centralised view of the network made it difficult to monitor, manage and respond to issues quickly.
‍

The Solution

Cello worked closely with Fulton Hogan's internal IT and security teams to design a modern, segmented network architecture that supported both centralised control and local autonomy.
‍

This began with the rollout of SmartWAN – Cello's flexible SD-WAN offering – tailored to the specific needs of different Fulton Hogan sites. To account for the variety in access types, Cello developed a modular design framework with five standardised configurations initially, which later grew to nine as Fulton Hogan's needs evolved.
‍

Secure firewalls, VLANs and application-level controls were deployed to ensure isolation and control across joint ventures, subsidiaries, and internal teams. Intrusion prevention, anti-virus and intelligent traffic shaping were implemented as standard.
‍

The entire solution was centrally managed and supported by Cello's Network Operations Centre (NOC), providing around-the-clock monitoring, alerting and remediation. The deployment extended to more than 150 sites, each tailored to its connectivity requirements, and established a single-pane-of-glass management approach that dramatically increased visibility and reduced resolution times.
