Dealership Network Setup in Winder, GA: Secure, Compliant Infrastructure for Auto Dealers

Auto dealerships in Winder and across Barrow County run on networks that handle more sensitive data than most businesses their size. A single floor plan connecting the showroom, service drive, F&I office, and parts counter must simultaneously support a DMS like CDK Global, Reynolds and Reynolds, or Dealertrack, while keeping customer financial data isolated from public Wi-Fi and technician tablets. COMNEXIA, headquartered in Roswell, GA and building dealer networks since 1991, designs and installs that infrastructure from the ground up, with FTC Safeguards Rule compliance (16 CFR Part 314) built into the architecture rather than patched on afterward.

Why Generic Network Setup Fails Dealerships

A flat network where the guest Wi-Fi, DMS workstations, and service-bay tablets share the same broadcast domain gives an attacker, or a curious customer on the showroom floor, a direct path to Reynolds and Reynolds or CDK Global terminals. The FTC Safeguards Rule requires dealerships to implement access controls that limit who can reach systems containing nonpublic personal information (NPI). A network that has never been segmented is, by definition, out of compliance on that requirement. Winder-area dealers who expanded quickly during the past several years often did exactly that, adding access points and printers without revisiting the underlying architecture.

How COMNEXIA Structures a Dealer Network

Every COMNEXIA dealership network engagement starts with a documented site survey that maps every wired drop, wireless access point, switch port, and upstream ISP circuit on the property. From that baseline, we build a segmented architecture using VLAN tagging enforced at the switch level, with traffic policies defined on a next-generation firewall.

• Firewall platform: We deploy Fortinet FortiGate or SonicWall appliances sized to the dealer's throughput. FortiGate's application-layer inspection profiles can identify and restrict CDK or Dealertrack traffic to authorized VLAN segments only, reducing lateral movement risk across the dealership floor.
• VLAN segmentation: Minimum segments include a DMS/POS VLAN for workstations touching the DMS and F&I tools, a guest VLAN for showroom Wi-Fi, a service-bay VLAN for technician tablets and alignment equipment, and a management VLAN for network infrastructure access. Each VLAN has its own inter-VLAN routing policy enforced at the firewall.
• Business Wi-Fi: We install and configure Ubiquiti UniFi or Cisco Meraki access points, placing SSIDs on appropriate VLANs and enabling client isolation on guest networks so showroom visitors cannot probe other connected devices.
• DMZ for dealer integrations: Systems that need to exchange data with third-party lenders, vehicle history APIs, or CRM platforms sit in a dedicated DMZ segment. Outbound rules are scoped to specific destination IPs and ports, not open internet egress.
• Remote access via VPN or ZTNA: General managers and controllers who need off-site access to the DMS receive site-to-site VPN tunnels or Zero Trust Network Access (ZTNA) policies rather than open RDP ports. FortiClient with ZTNA tags can enforce posture checks before granting a session.
• Structured cabling: Where runs do not exist or are out-of-spec, we install or certify Cat6 cabling with labeled patch panels and documented port mappings, so a future technician or auditor can trace every connection without guessing.

FTC Safeguards Rule Alignment

16 CFR 314.4 requires covered dealerships to designate a qualified individual, conduct a risk assessment, and implement a written information security program. The network architecture COMNEXIA delivers directly supports the access-control and monitoring requirements in that rule. Specifically, VLAN segmentation addresses the requirement to control access to customer NPI by role and system function. Firewall logging, forwarded to a centralized log repository, satisfies the monitoring and testing requirements. We provide documented network diagrams and configuration records that a dealer's qualified individual can attach directly to their WISP.

Ongoing Management After the Build

A correctly designed network degrades without active management. COMNEXIA monitors all network devices through NinjaOne RMM, which flags firmware update availability on FortiGate or Meraki appliances within hours of vendor release. Patch deployment is scheduled within documented change windows to avoid disrupting the DMS during peak sales hours. Monthly reports delivered to dealership management include firewall event summaries, blocked connection attempts by VLAN, and any open configuration exceptions with remediation timelines. Help-desk tickets from Winder staff are tracked through a structured ticketing system so no issue is resolved by word of mouth and every resolution is logged.

Serving Winder and the Surrounding Barrow County Area

Winder sits roughly 50 miles east of COMNEXIA's Roswell headquarters on US-29, close enough for on-site work without travel delays that leave a dealer down during a DMS outage. Barrow County's growing commercial corridor along GA-316 has brought new dealership activity to the area, and we are already familiar with the connectivity providers and building infrastructure common in that corridor.

Schedule Your Dealership Network Assessment

If your Winder dealership is running CDK Global, Reynolds and Reynolds, or Dealertrack on an unsegmented network, or if you are opening a new rooftop and need compliant infrastructure from day one, call COMNEXIA at (877) 600-6550. We will schedule an on-site walk-through, produce a written network diagram showing your current state, and deliver a segmentation plan with specific VLAN and firewall policy recommendations before any work begins.
