Reliable. Secure.
Operationally practical.
/ vendor-aware, requirement-driven
We work across major platforms and recommend technology based on what the business actually needs.
/ the problem
Hybrid teams, cloud services, office networks, VPNs, firewalls, Wi-Fi, and internal resources all need to work together. Without proper design, the network becomes difficult to secure, scale, and operate.
We help businesses make the right architecture decisions before complexity turns into outages, security gaps, or expensive redesigns.
pain.01
Remote employees need secure access to internal resources without exposing systems directly to the internet.
pain.02
Office Wi-Fi often performs poorly when access points are placed wherever it is convenient.
pain.03
Vendor proposals may not fully reflect customer-specific requirements, users, or traffic profile.
pain.04
Existing networks grow until they are hard to scale, change, or support without risk.
pain.05
The wrong WAN or VPN decision creates long-term operational and cost limitations.
pain.06
Missing documentation makes every future change a risky, expensive negotiation.
/ what we do
We design networks based on how your business works: users, locations, resources, applications, security needs, traffic, and future growth. Whether you are building a new network or improving an existing one — we define the right architecture, technologies, and implementation path.
Logical and physical architectures based on business requirements, users, locations, applications, and expected growth.
VPN and zero-trust style access for hybrid and remote teams who need protected access to internal resources.
SD-WAN, IPWAN, or firewall-centric — evaluated against traffic, security, support, and scalability needs.
Connectivity for resources hosted in cloud platforms, office server racks, or hybrid environments.
Wireless coverage planned around layout, density, and required features — not where it was convenient to mount the AP.
Equipment, vendor, and platform choices based on requirements, budget, support model, and future growth — not vendor pressure.
/ who we help
We work with companies that need practical, secure, and scalable network infrastructure — without unnecessary complexity or vendor-driven decisions. The conversation usually starts in one of these places:
use case · 01
Startups or new offices that need a structured foundation — from LAN and Wi-Fi to remote access and the internet edge.
use case · 02
Employees need secure access to databases, file shares, and private services from anywhere — without exposing them publicly.
use case · 03
Networks that grew organically and have become difficult to manage, secure, document, or scale to the next stage.
use case · 04
Evaluating the right WAN model for sites, users, security, traffic direction, and willingness to accept vendor lock-in.
use case · 05
Hybrid environments where resources live in the cloud, in an office server rack, or both — and need to be reachable safely.
use case · 06
Offices needing dependable wireless and wired connectivity, with deliberate AP placement, segmentation, and guest separation.
/ design principles
Every design starts with customer requirements — not with a predefined vendor solution looking for somewhere to land.
Remote access, inbound exposure, segmentation, and firewall policy are considered from the first sketch, not bolted on.
We say what the design can realistically support — users, traffic, sites — and where the practical limits actually are.
A good design must be possible to implement, support, and change over time — by the team that will actually run it.
We help customers choose technologies based on requirements, support expectations, and budget — including open-source where it fits.
The final design should be clear enough for technical teams, management, and future operators — not just the people who built it.
/ methodology
A successful network project starts before equipment is purchased. We follow a structured process that helps customers understand their requirements, compare design options, and agree on an architecture that is realistic to operate.
We collect business and technical requirements, constraints, existing pain points, and future plans. The goal is to know what the network actually has to do.
For existing networks, we review topology, access methods, traffic flows, security posture, and operational risks before recommending change.
We evaluate possible architectures — SD-WAN, IPWAN, firewall-centric, cloud-based access, hybrid — with explicit trade-offs.
Suitable vendors, platforms, and equipment are chosen against requirements, support expectations, budget, and future growth.
We prepare the target architecture: connectivity, security, segmentation, remote access, Wi-Fi, and infrastructure placement.
We define the realistic capacity boundaries of the proposed design — so “scalable” becomes a number, not a marketing word.
We review the proposed design with the customer, adjust where needed, and produce a final version the team can actually use.
Where required, we support implementation planning, configuration guidance, migration steps, and operational handover.
/ engineering background
Subnetworks.io is a focused engineering practice. Our background is in practical network design, routing and switching, secure access, cloud operations, and application delivery — across both vendor platforms and open-source environments.
We do not push complexity where it is not needed. We do not push a single vendor when the requirements point somewhere else. We design networks we would be willing to operate ourselves.
