Real results for banks, insurers and businesses across PNG and the Pacific

Since 2013 we have designed, secured and supported networks for organisations that cannot afford downtime. Here is what changed for them.

In short: Sprint Networks has delivered network design, SD-WAN and managed cybersecurity for banks, insurers, construction and healthcare clients in Papua New Guinea, Fiji, the wider Pacific and Australia. Clients include Westpac Pacific, Kina Bank, Capital Insurance Group, PMBL and Hornibrook NGI and Golden Manufacturers. The common thread is networks that stay online and secure on real Pacific links, with changeovers planned so the business barely notices.

ManufacturingSuva, FijiSD-WANZero trust access (ZTNA)Cloud ERP in Azure

From one fragile VPN tunnel to a tested, automatic backup path into a cloud ERP

Golden Manufacturers Limited (GML) · January 2026

The challenge

GML makes the cartons, packaging and labels behind some of Fiji's best-known products. Orders, stock, production and deliveries all run through Microsoft Dynamics 365 Business Central, hosted in Azure.

Everything reached the ERP through one firewall at head office in Suva, and only one of its two VPN tunnels worked. If that path failed, there was no automatic backup. Staff also needed secure access to the ERP when working away from the office, and the IT team had little visibility when problems came up.

What we did

  • Tested it first: built a working copy of the design in our Sydney lab before touching the live network.
  • Head office: two Versa SD-WAN appliances and new Cisco core switches, so no single device can cut off the ERP.
  • Two carriers: SD-WAN tunnels over Vodafone and Digicel internet, switching automatically when the main link struggles or fails.
  • Into Azure: a virtual Versa appliance inside GML's Azure environment, carrying firewall and traffic rules right up to Business Central.
  • Remote staff: Zero Trust Network Access (ZTNA), so approved users reach Business Central without broad access to the office network.
  • Automatic failover between two carriers, tested and working
  • No single piece of head office hardware can take the ERP offline
  • Secure remote ERP access for authorised staff
  • Business Central traffic prioritised over browsing and downloads
  • Clear network and application visibility for the IT team
  • Ready for branches to connect straight to Azure in the next phase

BankingPNG and FijiNetwork designManaged servicesSD-WAN

A world-class banking network across PNG and Fiji, supported around the clock

Westpac Pacific

The challenge

Westpac Pacific needed a clear split between its domestic and international services in Papua New Guinea and Fiji. That meant taking over legacy hardware from the previous provider without disrupting branches, then building a network that could grow with the bank.

What we did

  • Separated Westpac's network from the previous provider's managed services in both countries, then moved each device across to our management step by step.
  • Designed a new two-tier network on enterprise Cisco hardware with built-in redundancy and automatic failover for branches.
  • Segmented security in the data centres and encrypted traffic from every branch.
  • Took on ongoing managed support, tuning each Pacific branch's traffic priorities to its link capacity and monitoring the Digicel, TFL and Telikom links.
  • Later moved Westpac to a software-defined network (SD-WAN) for more flexibility, faster response and stronger security.
  • Smooth handover with no disruption to banking
  • Automatic failover for the branch network
  • Branch traffic tuned to each island link
  • Proactive support across the Pacific

"Today we're extremely proud to say we have one of the best IP data networks in PNG. The network performance is world-class."

Eddie Galele Jnr, Manager Networks, Westpac Pacific

"I recommended Sprint Networks to Westpac as I was so impressed with their expertise and knowledge, and also their energy, passion and 'can do' attitude."

From a legacy network to secure SD-WAN across the islands, with cutovers under 30 minutes

Capital Insurance Group (CIG)

The challenge

CIG was running on end-of-life routers, firewalls and unmanaged switches. It wanted to protect customer data, improve reliability and give its island branches the same secure, fast connection as head office in Port Moresby.

What we did

  • Head office and data centre: replaced end-of-life equipment, added a dual internet connection, a Cisco next-generation firewall and application controls so business systems get priority.
  • Secure SD-WAN: connected every island branch directly to head office and the disaster recovery (DR) site, all managed from one dashboard and a mobile app.
  • Swapped two legacy devices at head office and DR for a single banking-grade firewall at each.
  • Branches: new firewalls, managed switches, secure Wi-Fi and remote VPN access for staff.
  • Head office cutover in under 30 minutes, after hours
  • DR site cutover in 15 minutes
  • Each branch moved in under 30 minutes
  • Round-the-clock intrusion detection and web filtering
  • Whole network visible from a phone
  • Delivered on time and on budget

The network foundation for Kina Bank's integration of ANZ's PNG business

Kina Bank

The challenge

Kina Bank's corporate and banking networks ran on end-of-life hardware, just as it needed to bring ANZ's PNG branches, ATMs and core banking systems onto one network. The risk of a messy merger was high.

What we did

  • Planned the work in five phases so each step could be tested on its own.
  • New floor and core switches at Kina Haus and Waigani, then merged old and new core networks.
  • Designed active/active links between the two data centres with automatic failover.
  • Built a new branch and ATM network for both Kina and ANZ sites.
  • Ran two phases side by side to bring the ANZ integration forward.
  • One primary data centre (Waigani) with a backup DR site (Kina Haus)
  • Automatic failover between data centres
  • Branches and ATMs for both banks on one network
  • A ready platform to bring ANZ's business across

"Sprint Networks took it upon themselves to deliver an 'on-the-go' build that became a solid platform for us to integrate our business. The results speak for themselves."

Hornibrook needed to strengthen its defences at its PNG head office quickly. Its reputation, customer trust and data were on the line.

What we did

  • Installed a Fortinet next-generation firewall at head office.
  • Added endpoint protection to every device to scan continuously for threats.
  • Delivered it all as a monthly managed service, so there was no upfront hardware cost.
  • Our security engineers monitor and manage Hornibrook's security day to day.
  • Designed, configured and deployed in under three weeks
  • Every device protected and monitored
  • No upfront hardware cost

"We were in dire need of a security solution that would best fit our network and Sprint Networks gave us a solution that did that and more."

Patient data protected, and the clinic stays online when the internet drops

Dr Abbie Clinics

The challenge

A long-established medical practice with every system online, but no backup when the NBN went down, weak cybersecurity, patchy Wi-Fi, no secure data backup and no view of what was happening on the network.

What we did

  • Installed one all-in-one device as the heart of the network, with a built-in next-generation firewall.
  • Added automatic backup internet for when the NBN fails.
  • Gave the practice full visibility of its network from a mobile phone.
  • Rolled out fast, secure Cisco Meraki Wi-Fi 6 across the clinic.
  • Patient information protected from cyber threats
  • Clinic keeps running when the NBN is down
  • Fast, stable Wi-Fi across the whole clinic
  • Network visible and managed from a phone

"We were in dire need of a reliable solution that would secure our customer data, business systems and provide a backup option for the NBN. We appreciate Sprint Networks for delivering a complete cyber-security and NBN backup solution for us."
