One flat network
Staff laptops, the shop floor controllers, guest phones and printers all sit on the same network. One infected laptop can reach everything.
- VLAN segmentation
- Guest access separated
- Device traffic contained
Network management · Toronto & the GTA
A network that stays up, stays documented, and gets watched overnight.
Firewalls, switches, Wi-Fi and remote access designed, built and then managed by the same engineers. We monitor every device around the clock, keep the diagrams current, and review the rules before an incident does it for you.
Managed network services for offices, warehouses and multi-site operations across Toronto, Markham and Canada — on hardware from FortiGate, Palo Alto, Cisco, SonicWall, pfSense, Ubiquiti and Aruba.
- 24/7 monitoring and alerting
- Firewalls, Wi-Fi and switches managed
- Diagrams kept current, not drawn once
- No long-term contracts
What we look after
- Firewall rules, reviewed on a schedule
- Wi-Fi that holds up at 9am on a Monday
- Separate networks for staff, guests and devices
- Secure remote access for hybrid teams
- Current diagrams of every switch and circuit
The honest test: can a new engineer read your diagrams and fix a fault without calling anyone?
What goes wrong
Six reasons a network fails on an ordinary Tuesday.
None of them are dramatic. They build up quietly over years, then all show up in the same morning.
Firewall rules nobody reviewed
Years of temporary rules added for one project, ports opened to the internet and never closed, and nobody knows why half of it exists.
- Rule audit and cleanup
- Change log
- Documented intent
Wi-Fi tuned for an old floor plan
Coverage was fine when you had twelve people and no video calls. Now meetings drop whenever the warehouse is busy.
- Onsite or predictive survey
- Access point placement
- Channel planning
No diagrams
Nobody can say which switch feeds which office, or where the fibre terminates, so every fault starts with an hour of detective work.
- Automated discovery
- Port-level diagrams
- Kept current by us
Firmware years behind
Switches and access points running code with published vulnerabilities, because upgrading them means an evening nobody has.
- Patch windows planned
- Firmware tracked
- Tested before rollout
Nobody watching
A circuit, power supply or uplink fails at 7pm and you find out when the team arrives. The alerts were never set up.
- 24/7 device monitoring
- Uplink and power alerts
- Someone on call
Hardware we manage
- FortiGate
- Palo Alto
- Cisco
- Cisco Meraki
- SonicWall
- pfSense
- Ubiquiti
- Aruba
- Sophos
Network risk check
Eight questions. No sales call needed.
Answer honestly. Anything you mark as missing comes back with the fix, and you can take that list to whoever manages your network today.

Nothing answered yet.
Is guest Wi-Fi separated from the network your staff and servers use?
Are servers, cameras and building systems on separate VLANs from staff laptops?
Have your firewall rules been reviewed in the last twelve months?
Is remote access protected by multi-factor authentication?
Do you have current diagrams covering switches, ports and circuits?
Are switch and access point firmware updates applied on a schedule?
Would you know within minutes if a switch, uplink or circuit failed?
Do you have a second internet connection that fails over automatically?
Your result and priority fixes appear here.
What good looks like
Seven layers, each one doing its job.
A network is not one thing. When something breaks, it is usually the layer nobody was responsible for.
01
Firewall and perimeter
Rules you can explain, inbound access closed by default, and remote users arriving through a gateway rather than a published port.
02
Segmentation
Staff, servers, guest Wi-Fi, cameras and building systems on separate VLANs, so a compromise stays where it started.
03
Switching
Managed switches with spare capacity, redundant uplinks where it matters, and power that keeps the core up through an outage.
04
Wi-Fi
Enough access points for density, not just coverage, surveyed so calls and video hold up in the rooms people actually use.
05
Circuits and failover
Primary and secondary internet from different providers where available, with automatic failover and a working 4G or 5G backup.
06
Remote access
VPN or zero-trust access with multi-factor, scoped per role, so a stolen password alone does not open the network.
07
Monitoring and documentation
Devices watched around the clock, with diagrams, IP plan and credentials maintained as part of the service.
One team owns all seven.
No finger-pointing between the cabling contractor, the ISP and whoever set up the firewall.
Network services
Designed, built, then supported by us.
The team that installs it is the team that answers the phone afterwards — so nobody gets to pass the blame to a vendor.
Firewall management
Configuration, rules, change tracking and access oversight for FortiGate, Palo Alto, Cisco ASA and FTD, SonicWall and pfSense. Reviews on a schedule, not only after an incident.
Managed firewall Toronto
Wi-Fi management
Ubiquiti and Aruba access points designed, installed and tuned for density and coverage, with guest and staff networks kept apart.
Business Wi-Fi Toronto
Network design and builds
New offices, relocations and expansions designed end to end: structured cabling, switching, addressing and Wi-Fi, then supported by the team that built it.
Network design Toronto
Switching and segmentation
Managed switches with VLANs that separate staff, servers, cameras and building systems, and an addressing plan that survives growth.
VLAN segmentation
Secure remote access
VPN and zero-trust remote access with multi-factor and per-role scope, so people work from anywhere without exposing the network.
Secure remote access
24/7 monitoring and alerting
Devices, uplinks, power and performance watched continuously. A failed switch or a saturated link becomes a ticket, not a morning surprise.
Network monitoring
Documentation and diagrams
Automated discovery maps every node, port and circuit. You get diagrams that are updated as part of the service, not a PDF from 2019.
Network documentation
ISP and circuit management
Circuit procurement, failover design and vendor escalation. We chase the carrier so you do not spend the day on hold.

Cabling and site works
Structured cabling, rack builds, access control and camera networks for offices, warehouses and multi-site operations across the GTA.

How we work
No surprises, no mystery boxes.
You always know what is being changed, when it happens, and what to do if it goes wrong.
- 01
Discovery
We walk the site, log in to every device and map what is actually there, including the things nobody documented.
- 02
Diagram and audit
Current-state diagrams, an address plan and a list of risks ranked by what they would cost you.
- 03
Design
The target design: segmentation, Wi-Fi coverage, failover and remote access, sized to your headcount and growth.
- 04
Build
Changes made in planned windows, with rollback ready and staff told what will and will not be interrupted.
- 05
Hand over
Updated diagrams, credentials in safe storage and a plain-English summary of what changed.
- 06
Run and review
Monitoring, patching and quarterly reviews where we show you what was fixed and what is next.
