Services
Network design & engineering.
Labor only. You own the gear.
Network design services from senior engineers: redesigns, firewall replacement, Wi-Fi, remote access, segmentation and SD-WAN, documented so your own team can run it. You buy the equipment from whichever vendor you choose. We engineer it.
Network design and engineering services plan, build and document the network a business runs on. Pro IT NW, a Seattle-based, labor-only consultancy, designs and redesigns networks, replaces firewalls, cleans up rules, redesigns Wi-Fi, builds remote access, segments networks and deploys SD-WAN, then hands over documentation your team can run. We sell no hardware: you buy the gear from the vendor you choose.
What network engineering work do you do?
Design and hands-on engineering across the whole network, from the internet edge to the access point.
Network design and redesign
A clean addressing and VLAN plan, sensible switching, and a design that matches how the business works now, not how it looked when the network was first built.
Firewall replacement and rule cleanup
Years of rules reviewed one by one. What is still needed moves to the new firewall; what nobody can explain is retired, with a record of why.
Wi-Fi redesign
Access point placement, channel planning, and separate networks for staff, guests and devices, so coverage problems are fixed at the cause.
VPN and remote access
Remote access tied to your identity system with MFA, scoped to what each person needs rather than the whole network.
Segmentation
Servers, workstations, printers, cameras, guests and specialty devices kept apart, so one compromised machine cannot reach everything.
SD-WAN and multi-site
Connecting branch offices over more than one internet circuit, with failover and traffic priorities that are planned, tested and written down.
How does a network project run?
Five steps, scoped and priced before work starts.
- Discovery. We document what you have today: equipment, circuits, rules, and what is not working.
- Design. A written design with diagrams and an equipment requirements list, vendor-neutral.
- Purchase. You buy the hardware and subscriptions directly from the vendor you choose.
- Build and cutover. Staged configuration, a scheduled change window and a written rollback plan.
- Handover. Documentation, credentials in your hands, and a walkthrough or training for your team.
What do you get at the end?
A network your own team understands and controls.
- Network diagrams, physical and logical
- An IP addressing and VLAN plan
- Firewall rules documented with the reason each one exists
- Configuration backups and an equipment inventory
- All admin accounts and credentials held by you, not by us
- Hands-on training for your internal IT staff, if you want it
Why labor-only network engineering?
Because the design should not depend on what carries a margin. We sell no firewalls, switches, access points, licenses or circuits, so the recommendation is free to keep equipment that still works, or to pick a different vendor when it does not. You buy direct, you own the contracts, and the subscriptions are in your name.
Who is this for?
- Owners and operations leads whose Wi-Fi, VPN or branch connections keep causing complaints
- IT managers facing a firewall end of life or a messy rule base nobody wants to touch
- Small IT teams who need a senior network engineer for a project, not a permanent hire
- Not for: hardware resale, or a monthly support contract with no project attached

FAQ
Common questions about network engineering.
What do network design and engineering services include?
Pro IT NW's network engineering covers network design and redesign, firewall replacement and rule cleanup, Wi-Fi redesign, VPN and remote access, network segmentation, SD-WAN, and documentation and handover so your internal team can run what was built. It is labor only: we design, configure, cut over and document, and you buy the equipment.
Do you sell the firewalls, switches or access points?
No. Pro IT NW resells nothing and carries no hardware or license margin. We help you write the requirements, compare options from different vendors on their merits, and then you buy the gear and any subscriptions directly from the vendor or distributor you choose. We implement whatever you buy.
Which vendors do you work with?
We are vendor-neutral and hold no partner status with any network vendor. The design comes first and the brand second. If you already run one vendor's firewalls or switches and they meet the need, we usually keep them rather than replace working equipment.
Can you replace our firewall without taking the office down?
The cutover is planned so disruption is short and scheduled. We export and review the existing rules, rebuild only the ones still needed on the new firewall, stage and test the configuration before the change window, and keep a written rollback plan. The exact window depends on your sites and circuits and is agreed with you before the change.
Will our internal IT team be able to manage the network afterwards?
Yes, that is the point of the handover. You get diagrams, an IP and VLAN plan, firewall rule documentation, configuration backups and admin credentials held by you. We walk your team through the design and can run hands-on training on your own equipment, so nothing depends on us afterwards.
How is network engineering work priced?
Each project is scoped and priced up front after a call about your sites, users, current equipment and what is not working. There is no hourly meter and no retainer. Hardware, licenses and circuits are separate purchases you make directly from the vendor.
