Dealership Network Setup in South Fulton, GA

Dealership Network Setup in South Fulton, GA: Secure, Compliant Infrastructure from COMNEXIA

Auto dealerships in South Fulton and across Fulton County run on networks that carry customer financing data, DMS traffic, VoIP calls, service-bay devices, and sales-floor workstations simultaneously. A misconfigured switch or a flat network with no segmentation is not just an IT inconvenience, it is an FTC Safeguards Rule violation waiting to happen. COMNEXIA has designed and secured dealership networks in the metro Atlanta area since 1991, and our Roswell-based team builds infrastructure that keeps CDK Global, Reynolds and Reynolds, and Dealertrack environments running while protecting the customer financial data those systems touch.

Why Dealership Networks in South Fulton Require a Different Approach

The FTC Safeguards Rule (16 CFR Part 314) requires dealerships to implement an information security program that includes encryption in transit, access controls, and network monitoring. A generic office network does not satisfy those requirements. Dealerships must also contend with DMS vendors that publish strict firewall and port requirements, F&I platforms that transmit non-public personal information (NPI), and service departments that connect scan tools and loaner devices to the same physical infrastructure as the business office. Mixing those traffic types on a single flat network is both a security risk and a compliance gap.

What COMNEXIA Delivers: Specific Components of a Dealership Network Build

Every dealership network setup COMNEXIA completes for South Fulton clients includes the following concrete elements:

• Next-generation firewall deployment: We configure Fortinet FortiGate or SonicWall firewalls with application-aware policies, IPS signatures enabled, and SSL inspection rules tuned to avoid breaking CDK or Reynolds and Reynolds DMS traffic while still inspecting outbound sessions for data exfiltration.
• VLAN segmentation and DMZ design: We create discrete VLANs for DMS workstations, F&I terminals, guest Wi-Fi, service-bay devices, VoIP, and management traffic. Inter-VLAN routing is restricted at the firewall layer so that a compromised loaner-return kiosk cannot reach the finance office segment.
• Business Wi-Fi with Ubiquiti UniFi or Cisco Meraki: Access points are deployed with SSIDs mapped to the correct VLANs. The customer-facing guest SSID is isolated with client isolation enabled and bandwidth throttled. The DMS SSID requires WPA3 Enterprise authentication where the hardware supports it.
• Structured cabling and physical documentation: We document every port, patch panel location, and switch uplink with labeled diagrams that remain on-site, so any technician (ours or the DMS vendor's) can trace a connection without guessing.
• VPN and ZTNA remote access: Remote staff and off-site managers connect through FortiClient VPN or FortiGate ZTNA policies with multi-factor authentication enforced, rather than through open RDP ports. This directly addresses the Safeguards Rule's access-control requirement.
• Dealertrack and F&I integration validation: After cabling and firewall configuration are complete, we test connectivity to Dealertrack's credit bureau and lender portals, verify that F&I workstation traffic routes through the correct VLAN, and confirm that NPI does not traverse the guest or service network.
• RMM agent deployment and patch management baseline: Every endpoint and network device is enrolled in NinjaOne so COMNEXIA can push OS and firmware patches, receive real-time alerts on firewall policy violations, and produce the monthly network health reports that satisfy the Safeguards Rule's annual risk-assessment documentation requirement.

A Realistic South Fulton Dealership Scenario

Consider a South Fulton independent used-car dealer running Reynolds and Reynolds ERA-IGNITE on four finance-office workstations, a service lane with two service advisors sharing a Wi-Fi-connected tablet, and an open guest Wi-Fi network that customers and employees use interchangeably. That configuration puts ERA-IGNITE DMS traffic on the same broadcast domain as unauthenticated devices, creates a clear path for lateral movement, and produces no audit log that could satisfy an FTC examiner. COMNEXIA replaces that flat network with a FortiGate firewall, three VLANs (DMS, service, guest), and a UniFi access point deployment that maps each SSID to the correct VLAN. Reynolds and Reynolds connectivity is re-validated against ERA-IGNITE port requirements before go-live.

Ongoing Management After the Build

A network build is not a one-time event. COMNEXIA monitors the FortiGate or SonicWall security event log continuously through NinjaOne integrations, applies firmware updates on a documented maintenance schedule, and delivers a monthly report showing firewall policy hits, patch compliance percentage, and any new devices that appeared on the network. That report doubles as supporting documentation for the dealership's Safeguards Rule written information security program (WISP).
