Commercial-grade cabling, Wi-Fi, switching, and network security — designed, installed, and supported by Nexasec’s technical specialists across Victoria.
Design & Consult
Every project starts with a thorough site survey and infrastructure assessment. We design a network that meets your current needs and scales with your business.
Supply & Install
We supply and install all hardware — cabling, switches, access points, racks, and security appliances — to the highest installation standards.
Commission & Support
Full configuration, testing, and documentation before handover. Ongoing support agreements available to keep your network reliable and up to date.
Network Services
From a single office fit-out to a multi-site enterprise rollout — our technical team delivers complete network infrastructure you can rely on.
Structured Cabling
Cat6, Cat6A, and fibre optic data cabling for commercial fit-outs. Patch panels, cable trays, labelled runs, and clean terminations built to AS/NZS standards.
Enterprise Wi-Fi
High-density wireless design with professional site surveys. Ubiquiti, Cisco, and Aruba HPE deployment with separate guest and corporate SSIDs.
Network Design & Architecture
Full topology planning from the ground up — IP addressing, VLAN segmentation, bandwidth modelling, and documentation for every node in your infrastructure.
Network Security
Firewall deployment, VPN configuration, and network segmentation that keeps your data and devices separated and protected. Intrusion prevention and secure policy design.
Managed Switching & Routing
Layer 2 and Layer 3 switching, managed switch configuration, routing protocols, and QoS policies tuned for voice, video, and security traffic.
Server Room & Rack Build-Out
Structured data room fit-outs — rack installation, cable management, blanking panels, power distribution, labelling, and tidy documentation for every connection.
VPN & Remote Connectivity
Site-to-site VPN, remote worker access, and SD-WAN solutions that connect your offices and people securely — without sacrificing speed or reliability.
Network Maintenance & Support
Proactive monitoring, firmware updates, fault response, and scheduled maintenance under SLA-backed support agreements. We keep your network running at peak performance.
Networks Built for Security.
Most IT companies build networks for general productivity. Nexasec builds networks that carry your security infrastructure — CCTV, access control, and intercoms — alongside your business data. That distinction matters.
Discuss Your ProjectEnd-to-End Design
We design, supply, install, and commission every component — one team responsible for the entire infrastructure, from cabling to configuration.
Security-First Architecture
Every network we build is designed with segmentation and access control in mind. Your CCTV, access control, and data networks stay separated and protected.
Integrated with Your Security
Nexasec builds networks that carry your security systems. CCTV, access control, and intercoms run on infrastructure we designed — no compatibility surprises.
Post-Install Support
We don’t disappear after handover. Ongoing maintenance agreements, remote monitoring, and priority fault response keep your network running long-term.
