Who we are

A specialist IT firm for businesses that can't afford downtime.

Professional industries handle sensitive data, run on interconnected systems, and sit squarely in the crosshairs of modern attackers. Generic IT support isn't enough — you need a team that lives and breathes network security.

ionet proactively hardens your security posture, keeps operations running smoothly, and protects the confidentiality, integrity, and availability of your client data.

  • Cybersecurity-first network design
  • Continuous monitoring, patching & response
  • Disaster recovery you can actually rely on
  • Personal service — direct access to senior engineers

What we do

Managed IT services, end to end

From cybersecurity hardening to greenfield network builds, our engineers handle the full stack so you can focus on running the business.

Cyber Security

End-to-end defence: SIEM-driven monitoring, EDR/XDR rollouts, vulnerability management, penetration testing, phishing simulations, identity hardening, and full incident response. We map your posture against ASD Essential Eight, ISO 27001, and the ISM, then close the gaps systematically.

Integrated Communication Networks

Voice, video, and data unified on one resilient backbone — SIP trunking, hosted PBX, contact centre platforms, video conferencing, and unified messaging. Carrier-grade SD-WAN and MPLS underlays with QoS that keeps every call clear and every meeting stable, including for distributed and remote teams.

Network Design

Greenfield architectures and brownfield refreshes — campus LAN, data-centre fabrics (VXLAN/EVPN), WAN, and DMZ. Capacity-planned, segmented with zero-trust microsegmentation, and documented in low-level designs your team can actually maintain. Built to be reviewed, audited, and grown.

Network Automation

Move from CLI to code: Ansible, Terraform, Python with NAPALM/Netmiko, NetBox source-of-truth, and CI/CD pipelines for network change. Drift detection, golden configs, and validation before every push. Faster changes, fewer outages, and a network that scales without scaling headcount.

Network Deployment

Multi-site rollouts, structured cabling, rack-and-stack, and on-floor commissioning. Pilot lab validation, staged cutovers with rollback plans, and post-deployment as-builts. We hand back a network that runs — and the documentation that proves how it does.

Wireless Technologies

Wi-Fi 6 / 6E / 7, mesh, point-to-point bridging, and high-density venue design. Predictive and on-site RF surveys, RADIUS / 802.1X integration, rogue detection, and guest captive portals. Wireless that holds up in warehouses, stadiums, and packed open offices.

Cloud Solutions

Strategy, migration, and run-state operations across AWS, Azure, and hybrid. Landing zones, IAM hardening, FinOps cost control, Kubernetes platforms, and DR-into-cloud. We help you ship faster without leaving the door wide open behind you.

Service Provider Consulting

Carrier-grade engineering — MPLS, segment routing (SR-MPLS, SRv6), BGP, peering and transit strategy, DDoS scrubbing, NFV and SD-WAN platforms. We've worked inside ISPs, CSPs, and managed-service providers, and we bring that operational discipline to your network.

Proactive Maintenance

24/7 monitoring with disciplined alert hygiene, scheduled patching windows, firmware lifecycle management, hardware replacement, and capacity reviews. Quarterly health reports so issues are surfaced and resolved before they become incidents.

Proudly Australian

Engineered here. Built for here.

ionet is headquartered in Melbourne and supports clients across every state and territory. We work to the ASD Essential Eight, the Information Security Manual (ISM), and the Privacy Act 1988 — and we keep your data on Australian soil unless you tell us otherwise.

Local engineers, local service hours, and a deep understanding of the Australian regulatory landscape, the local NBN/carrier ecosystem, and what "remote and on-site" really means when the next site might be 1,500 km away.

  • Melbourne HQ, nationwide service coverage
  • Compliant with Australian privacy and data-sovereignty rules
  • On-site visits across capitals and regional centres
  • Familiar with NBN, NBN Enterprise Ethernet, dark fibre, and major carrier products

Cybersecurity

Defence in depth, not a single firewall.

The threat landscape doesn't sit still — and neither do we. We build a layered defence around your business, from the perimeter to the endpoint to the human in the chair, then continuously test, tune, and exercise it.

Our cybersecurity practice is grounded in real frameworks (Essential Eight, ISO/IEC 27001, NIST CSF, ISM) but driven by what actually works in the field: visibility, segmentation, identity, and rehearsed response.

  • SIEM & 24/7 monitoring — Microsoft Sentinel, Splunk, Elastic correlation and threat-hunting playbooks.
  • EDR / XDR — managed endpoint defence with Defender, CrowdStrike, or SentinelOne.
  • Vulnerability management — continuous scanning, prioritised remediation, and patch governance.
  • Penetration testing — internal, external, web app, and red-team engagements with actionable reports.
  • Identity hardening — MFA, conditional access, SSO, privileged access management, and access reviews.
  • Phishing & awareness — simulated campaigns, role-based training, and a measurable culture program.
  • Compliance — Essential Eight uplift, ISO 27001 readiness, ISM, NIST CSF, and SOC 2 mapping.
  • Incident response — IR plans, tabletop exercises, retainers, and rapid containment when it counts.
  • Source of truth — NetBox / Nautobot as the canonical inventory and intent model.
  • Configuration as code — Ansible, Jinja templates, and Git-versioned device configs.
  • Infrastructure as code — Terraform for cloud networking, firewalls, and DNS.
  • CI/CD for networks — GitLab / GitHub Actions pipelines with peer review and pre-deploy validation.
  • Drift detection & remediation — automated reconciliation against the source of truth.
  • API-first — gNMI, NETCONF, RESTCONF, and vendor SDKs over screen-scraping.
  • Streaming telemetry — model-driven telemetry into Prometheus, InfluxDB, and Grafana.
  • ChatOps — Slack and Teams integration so the network speaks where your team works.

Network Automation

Stop typing into routers. Start shipping changes.

The networks that scale aren't the ones with the smartest engineers — they're the ones with the best automation. We help you treat the network like software: declared, reviewed, tested, deployed, and observed.

That means changes that take minutes instead of nights, with rollback you actually trust. It means new sites that stand up from a template instead of a runbook. And it means engineers freed from copy-paste so they can solve real problems.

Integrated Communication Networks

One network. Voice, video, data — all of it.

ICN is what happens when communications stop being separate systems bolted to your network and start being a first-class citizen of it. Voice quality, video reliability, and contact-centre uptime aren't accidents — they're the result of a network designed end-to-end with these workloads in mind.

We design and operate integrated communication networks for businesses that depend on every conversation getting through — clinical practices, legal and finance teams, contact centres, multi-site retail, and distributed engineering organisations.

  • Voice platforms — Cisco UC, Microsoft Teams Phone, hosted SIP-PBX, on-prem and cloud.
  • SIP trunking & number porting — carrier-redundant trunks with failover routing.
  • Contact centres — omnichannel routing, IVR, recording, WFM, and analytics.
  • Video & collaboration — meeting rooms, BYOD, recording, and federation.
  • SD-WAN & MPLS — application-aware routing with QoS that prioritises real-time traffic.
  • Unified messaging — voicemail-to-email, presence, IM, and mobility.
  • Wireless calling & DECT — roaming voice across the building, the campus, and beyond.
  • E911 / emergency routing — compliant location services and dynamic call routing.

Our philosophy

We go above and beyond. Always.

Some call it old-fashioned. We call it the right way to do business. Strong relationships between us and our clients benefit everyone — and our commitment to mutual respect and exceptional service is what motivates us to go the extra mile, every time.
