Senior from day one
The engineer scoping your network is the one designing it, building it and supporting it. No graduates billing senior rates. No hand-off after sign-off.
Solution
Network Services.
Networks that keep your business moving.
Networks designed, built and then actually run by the same team - campus Wi-Fi through to data centre fabric. We work across vendors, but you only ever have one number to call when something breaks.
Most networks we are asked to look at were designed for a building full of desks. The traffic has since moved to the cloud and the people have moved to their kitchens, and the design underneath never caught up. That is usually the real problem, not the hardware.
Most people arrive here via a referral. If that's you, here's who to call.

Why Onel
One partner. The full network lifecycle.
Most organisations end up coordinating between a designer, a integrator and a support vendor. Each pointing at the others when something breaks. Onel owns it end to end: same senior team from architecture through to 3am call.
Independent by design
Partnerships across Cisco, Aruba, Palo Alto, Fortinet and Zscaler. We recommend what's right for your environment, not what's easiest to sell this quarter.
Past go-live
24/7 managed services aren't an afterthought. We run networks for Bayside, Manningham, Nillumbik and others, for years past the initial build. Read the council case studies.
What we do
Every layer of your network. Covered.
From the office floor to the data centre to the cloud. Onel designs, builds and manages the complete network stack so your business can operate with confidence.
Campus & Office Networking
Connected, reliable, everywhere
A campus network is doing its job when nobody mentions it. Wired and wireless for offices and multi-site environments, designed so the failure of any one piece is an inconvenience rather than a phone call.
- →Wired networking + enterprise Wi-Fi
- →High-density wireless
- →Guest access & segmentation
- →Multi-site campus design
SD-WAN & branch connectivity
Connect every location, intelligently
Legacy WAN is expensive and inflexible. SD-WAN replaces it with intelligent, cloud-managed connectivity that routes traffic automatically over the best available path, MPLS, broadband or 4G/5G.
- →SD-WAN design & deployment
- →Branch connectivity
- →Cloud on-ramp
- →Failover & redundancy
Data Centre Networking
The backbone of your infrastructure
High-performance, fully redundant data centre fabrics built to support virtualisation, private cloud and hybrid environments, without a single point of failure. Built to sit alongside our data centre solutions and managed private cloud platforms.
- →Data centre fabric design
- →High availability
- →Private cloud ready
- →Automated failover
Next-Generation Firewalls
Stop threats at the network edge
Very little arrives through the front door any more. Next-generation firewalls read traffic at every layer, which is what lets them stop a phishing payload that looks exactly like ordinary web traffic to an older device. Firewall policy sits inside the broader IT security services we deliver.
- →Threat prevention & IPS
- →Web filtering
- →Malware protection
- →DNS security & application control
Secure Remote Access
Work from anywhere, safely
Whether your team is in the office, at home or travelling, safe, reliable access to the tools and systems they depend on. Remote access designed-in, not bolted on.
- →VPN with identity checks
- →Multi-factor authentication
- →Device compliance
- →Cloud-delivered access (SASE)
Network Access Control
Right people, right systems
Not every device should reach everything. NAC automatically identifies who and what is connecting, enforces access policies, and quarantines anything that doesn't belong.
- →Device profiling
- →Role-based access
- →Guest isolation
- →IoT segmentation & posture checks
Security philosophy
Zero Trust. Never assume. Always verify.
The old model assumed everything inside the office was safe. That model is broken. Ransomware, compromised credentials and rogue devices mean threats are already inside most networks.
Onel builds networks on Zero Trust principles: every user, every device, every connection is verified before it gets access. Trust is earned at every step, not assumed at the door.
01
Verify every identity
Every login is checked against your directory with multi-factor, including the ones from inside the building. That last part is the whole point.
02
Check every device
Only devices meeting your security standards get access. Unmanaged personal devices, compromised endpoints and unknown hardware are blocked automatically.
03
Limit what you can reach
People only see the systems they need for their role. A breach in one area can't spread across the whole business.
Stop lateral movement
If an attacker gets in, network segmentation means they can't move through your organisation and reach critical systems.
See everything
Full visibility into every device and user on your network, so threats are spotted before they become incidents.
Works everywhere
Zero Trust protects users whether they're in the office, at home or accessing cloud apps from anywhere in the world.
Supports compliance
Demonstrating access controls, audit trails and device compliance is straightforward, supporting Essential Eight, ISO 27001 and more.
Built around your business, not your perimeter
Modern work doesn't happen inside a building anymore. Zero Trust means your security travels with your people: to the office, the home, the data centre and the cloud, enforcing the same standards everywhere, automatically.
How we work
From requirements to running one partner.
Onel handles the full network lifecycle, so you don't coordinate between a designer, an integrator and a support team.
Understand
We start by understanding your business: how your people work, where your systems live, and what gaps exist in the current environment.
Design
Our engineers produce a detailed design tailored to your requirements: covering architecture, security, redundancy and integration with existing systems.
Build & test
We implement the design, configure every device, and test against agreed acceptance criteria before handing over to operations.
Manage
After handover the network is monitored and patched by our team. Most of what we fix is something you never hear about, which is the intended outcome and also the hardest part of the service to demonstrate. Complex faults escalate to our IT infrastructure support services team.
Technology partners
Industry-leading platforms. Independent advice.
Onel holds deep expertise across all major enterprise networking and security platforms, so we recommend what's right for your environment, not what's easiest for us to sell.

When to call us
Common network challenges we solve.
Most of our network conversations start with one of these. If something here sounds familiar. We've fixed it before.
01
Unreliable wireless
Poor Wi-Fi coverage, dropped connections and slow speeds in high-density areas: meeting rooms, open-plan offices, classrooms.
02
Flat networks with no segmentation
When every device can reach every other device, a single ransomware infection can spread across the entire organisation.
03
Expensive WAN contracts
Paying for MPLS circuits sized for a different era: before cloud, before remote work, before the applications you run today.
04
Network refresh or migration
End-of-life equipment, a new office fit-out, a merger, or a move to a new data centre. You need a trusted partner to plan and execute the transition.
05
Remote work security gaps
Staff working from home or on the road with VPN that doesn't check device health or enforce consistent security policies.

FAQ
Questions we get before first call.
If your question isn't answered here, the fastest way to a clear answer is a 15-minute phone call. No sales pitch, no obligation.
1300 609 101 →Do you push one vendor's gear, or design for what fits?
We hold accreditations across Cisco, Aruba, Palo Alto, Fortinet and Zscaler. The right answer depends on what you're already running, what your team can support, and where the workload is going next. We recommend based on fit, not on vendor incentive - and we put the trade-offs in writing so your team can challenge them.
Who actually responds at 3am when the WAN goes down?
A senior Onel network engineer - the same team that designed and built the network. P1 incidents get a 15-minute response, 24/7, with proactive monitoring across every device on your fabric. Not a Tier 1 reading from a script.
How do we transition from our current network or MSP without downtime?
We run a discovery phase to document the existing environment, then design a phased cutover - site by site, VLAN by VLAN, or campus by campus depending on scope. Cutover windows happen after-hours with rollback plans agreed in writing. We've done this for councils, water authorities and enterprise clients without business-hours impact.
