Use Cases
Government & Public Sector
Use Case
Optimising Connectivity Through an SD-WAN Assessment
Situation
A government department sought to modernise its network infrastructure to support cloud-based applications and hybrid working across multiple agencies.
Challenge
Legacy WAN links lacked agility and visibility, leading to inconsistent performance and rising connectivity costs.
Solution
NEC conducted an SD-WAN Assessment, analysing traffic patterns, application usage, and security posture to design a roadmap for secure, cloud-optimised networking.
Outcome
Improved performance, reduced operating costs, and a clear migration path toward a scalable SD-WAN architecture.
Education
Use Case
Delivering Seamless Campus Connectivity with a Predictive Wireless Survey
Situation
A tertiary education provider needed to enhance Wi-Fi coverage to support BYOD learning and high-density lecture halls.
Challenge
Existing wireless infrastructure caused signal dead zones and unreliable performance in key areas.
Solution
NEC performed a Predictive Wireless Survey, using advanced modelling and site analytics to optimise access point placement and ensure reliable coverage.
Outcome
Consistent high-speed Wi-Fi, improved user experience, and full wireless coverage across all facilities.
Healthcare
Use Case
Reliable Connectivity for Critical Operations
Situation
A large hospital network needed to modernise its legacy infrastructure to improve connectivity between facilities, ensure system uptime, and maintain data compliance.
Challenge
Outdated network design caused intermittent outages and limited the performance required for clinical operations.
Solution
NEC delivered a Network Design and Architecture solution, providing high-availability connectivity with proactive monitoring and built-in security.
Outcome
Reliable 24/7 operations, improved collaboration, and predictable network costs..
Utilities
Use Case
Improving Cyber Resilience Through an OT Security Assessment
Situation
A major energy provider needed to assess vulnerabilities in its operational technology (OT) systems supporting critical monitoring and control.
Challenge
Legacy systems and limited segmentation increased exposure to cyber risk across plant and field environments.
Solution
NEC conducted an OT Security Assessment, identifying vulnerabilities, mapping interdependencies, and developing a mitigation roadmap aligned to industry standards.
Outcome
Improved visibility, reduced cyber risk, and enhanced operational resilience.
Entertainment Venues and Stadiums
Use Case
Frictionless Entry & Network Security
Situation
West HQ, operator of the Sydney Coliseum Theatre, required a secure, high-performance network to support facial recognition entry for thousands of patrons while maintaining compliance with NSW Liquor and Gaming regulations.
Challenge
Existing infrastructure lacked the capacity, reliability, and security to support large-scale biometric systems and compliance standards.
Solution
NEC delivered a Network Design and Architecture solution using Cisco switching, Meraki wireless, and firewall technologies to underpin the venue’s facial recognition system powered by NEC NeoFace.
Outcome
Seamless entry within seconds, enhanced network security, simplified management, and a future-ready digital foundation.
Financial Services & Insurance
Use Case
Reducing Costs with a Cisco Software License Management Assessment
Situation
A large financial institution wanted to control software spend and reduce audit risk across its complex Cisco licensing environment.
Challenge
Untracked and underutilised licenses were creating unnecessary costs and compliance uncertainty.
Solution
NEC delivered a Cisco Software License Management Assessment, analysing license usage, contracts, and entitlements to identify savings and ensure compliance.
Outcome
Reduced expenditure, optimised licensing, and improved governance across all Cisco environments.
