Network Design & Management

A Network That's a Platform, Not a Liability.

Business-grade network design, deployment, and 24/7 monitoring for Dallas–Fort Worth offices. Segmented, monitored, and documented — so your firewall isn't the reason your compliance audit fails.

The real problem

Most SMB Networks Are One Consumer Router From a Breach.

Walk into an average 40-person DFW office and you'll find a consumer-grade router from 2017, one flat network where the guest Wi-Fi shares a subnet with the file server, a printer that's been broadcasting SMBv1 for three years, and a firewall log nobody has ever read.

The MSP will tell you "the network is fine" because the internet works. That's not what fine means. Fine means guest traffic can't see servers, IoT devices are isolated from workstations, remote workers connect via a real VPN with MFA, and every rule change is documented with a reason.

Real network design is an architecture problem, not a hardware purchase. We design for segmentation, monitoring, and defensibility — then document it in a way that survives your next auditor, insurance renewal, or MSP change.

Flat SMB network

  • One VLAN — guest sees servers
  • Consumer router as gateway
  • IoT & staff on same subnet
  • No network diagram — or an old one

48 Technologies network

  • Segmented VLANs by traffic type
  • Business-grade firewall (Fortinet/Meraki/pfSense)
  • IoT & guest isolated from production
  • Documented diagram that matches reality
What's included

Four Pieces That Make a Network Defensible.

Buying a firewall isn't a network strategy. Real infrastructure is four disciplines working together — designed, deployed, monitored, and documented.

Design & segmentation

  • VLAN architecture by traffic class
  • Guest / IoT / staff / server isolation
  • Zero-trust posture where feasible
  • Growth plan for the next 3 years

Firewall & edge security

  • Business-grade appliance (Fortinet, Meraki, pfSense)
  • Rule set reviewed quarterly, not annually
  • IDS/IPS with actual signature tuning
  • External attack-surface scan monthly

Wireless & remote access

  • Managed Wi-Fi (Meraki, Ubiquiti UniFi)
  • Guest network on separate SSID + VLAN
  • MFA-protected VPN for remote workers
  • Site-to-site VPN for multi-office

Monitoring & documentation

  • 24/7 uptime & performance alerts
  • Netflow / firewall log ingestion
  • Current network diagram, quarterly refresh
  • Rule-change log with reason & owner
How we get you there

From "It Works, I Think" to Documented & Defensible.

Network transformation isn't a rip-and-replace — it's staged over 60 days so nothing breaks and every change is documented as it happens.

Week 1–2 — Discover

Map what's actually there.

Full network discovery: every switch, every VLAN, every firewall rule, every wireless AP. Compared to the diagram we were told exists. The gap between reality and documentation is where the risk lives.

  • Physical & logical topology map
  • Firewall rule inventory
  • Wireless coverage & interference survey
  • Written gap register
Week 3–6 — Design & stage

Design the target. Order the gear.

Segmentation plan drafted with your team. Business-grade firewall and wireless selected (usually Meraki or Fortinet for full-stack, UniFi for cost-conscious). Configured off-network before deployment.

  • Target VLAN & segmentation design
  • Hardware selection & procurement
  • Off-network pre-configuration
  • Change window scheduled with stakeholders
Week 7–8 — Deploy & document

Cut over. Then write it down.

Staged cutover, usually a Saturday morning. Every firewall rule migrated with a documented reason. Diagrams updated to match reality. Monitoring enabled from day one.

  • Off-hours staged cutover
  • Firewall rules migrated + documented
  • Live network diagram published
  • 24/7 monitoring active
How we price

Design Once. Monitor Monthly. No Surprises.

Network engagements split into two lines: a one-time design & deployment charge (scoped to office size and complexity) and an ongoing monitoring & management retainer. Deployments typically run $6,000–$45,000 depending on square footage, number of offices, and whether we're refreshing existing gear or greenfield. Ongoing management is bundled into managed IT or standalone at $6–$14 per user per month for network-only.

One office or ten? Multi-office deployments benefit from a standard reference architecture we deploy once and copy. Each additional office is meaningfully cheaper than the first because the design work is done.
  • 1. 1. Office count & sizeOne 5,000 sq ft office is very different from three offices with site-to-site VPN. Square footage drives access-point count; office count drives design complexity.
  • 2. 2. Firewall & wireless tierMeraki full-stack is different from Fortinet-plus-UniFi. We recommend based on your compliance needs, not the vendor with the best MSP margin.
  • 3. 3. Compliance requirementsHIPAA, PCI, and CMMC each add specific network controls (segmentation depth, logging retention, IDS/IPS tuning). We price the compliance overlay separately.
The alternatives

Consumer Gear vs. 48 Technologies vs. Enterprise Network Team

Three ways to run a network at a 25–150 employee DFW business. Only one of them is defensible in an audit without turning your office into a data center.

Consumer / Prosumer Gear

Whatever Best Buy had that Saturday
  • Consumer router at the edge
  • One flat VLAN, no segmentation
  • No IDS/IPS, no log retention
  • Nobody monitors it
  • Fails HIPAA / PCI / CMMC audits
  • Insurance carrier flags it
Cheapest — until the audit or the breach

48 Technologies Network

Designed, deployed, monitored, documented
  • Business-grade firewall + segmentation
  • 24/7 monitoring & alerting
  • Quarterly rule review
  • Diagrams that match reality
  • Audit- & insurance-defensible
  • Bundled with managed IT or standalone
Enterprise discipline — SMB economics

In-House Network Team

Senior net-eng + junior + tools
  • $180K+ fully loaded for 2 people
  • $40K–$80K in tooling stack
  • Requires 24/7 shift rotation for real
  • 12+ months to hire in DFW
  • Great — once you're 300+ people
  • Turnover risk on single admin
Right for enterprise — overkill for SMB
Tom Cloud, founder of 48 Technologies
At Lehman we ran the network like every packet mattered — because every packet was tied to a trade. That same discipline scales down. A 40-person business deserves segmentation, monitoring, and documentation. They just deserve it at an SMB price.
