Dealership IT Services in Chamblee, GA: Managed Security for Auto Dealers

Auto dealerships in Chamblee and across DeKalb County run on tightly connected systems: a DMS feeding finance, a CRM pushing leads, and F&I desks handling sensitive consumer credit files every hour of every business day. When those systems are misconfigured, unpatched, or improperly segmented, the exposure is not theoretical. The FTC Safeguards Rule (16 CFR 314.4) requires dealerships to implement a written information security program, designate a qualified individual to oversee it, and enforce specific technical controls. COMNEXIA has spent 35 years, since 1991, building the security-first infrastructure that dealerships need to meet those requirements and keep their operations running without interruption.

Why Chamblee Dealerships Face a Distinct IT Risk Profile

Chamblee sits at the intersection of Buford Highway commercial corridors and the broader Atlanta metro, with dealership groups managing multiple rooftops across DeKalb and Gwinnett counties. That multi-location reality means DMS data, including nonpublic personal financial information, moves across networks that are rarely reviewed for proper segmentation. CDK Global, Reynolds and Reynolds, and Dealertrack each carry their own API connections, vendor remote-access pathways, and integration points with RouteOne or Dealertrack's F&I portal. Every one of those connections is a potential vector. COMNEXIA's first task on any dealership engagement is to map and document every vendor touchpoint before touching a single configuration.

What COMNEXIA Delivers for Dealerships

Our dealership IT engagements begin with a structured onboarding process that produces a documented network diagram, an asset inventory, and a risk assessment aligned to the six required elements of 16 CFR 314.4. From there, we deploy and maintain a specific stack built for dealership environments:

• DMS network segmentation: CDK Global, Reynolds and Reynolds, and Dealertrack require isolated network zones. We configure a dedicated DMZ for DMS traffic, separating it from general office, guest Wi-Fi, and service-bay networks using VLAN tagging and firewall ACLs, so a compromised service-bay device cannot reach deal jacket data.
• Endpoint detection and response: SentinelOne EDR is deployed on every workstation and server, including finance office machines and any endpoint with a Dealertrack or RouteOne session. Behavioral detection runs at the kernel level, not just signature matching.
• Patch management via NinjaOne RMM: We enforce a documented patch cycle, critical OS and DMS-adjacent software patches within 72 hours of release, with automated deployment and a monthly compliance report showing every endpoint's patch status by age and severity.
• Identity and access control: Microsoft Entra ID conditional access policies enforce MFA on all cloud-connected accounts. Access to F&I and DMS modules is scoped by role, and we document every privileged account per the Safeguards Rule's access control requirement under 314.4(c)(3).
• Encrypted data handling: Drives on all F&I workstations are encrypted with BitLocker, and we enforce TLS 1.2 or higher on any internal application transmitting nonpublic personal information, consistent with 314.4(e) encryption requirements.
• Help desk with ticketing: Dealership staff get a named help-desk queue with ticket tracking. Every incident is logged with open, response, and resolution timestamps, giving your Qualified Individual a paper trail for the annual Safeguards Rule audit.
• Monthly reporting: Each month you receive a written report covering patch compliance, open vulnerabilities, EDR detections and dispositions, and any access anomalies. This report can be presented directly to your dealer principal or board as evidence of program oversight.

A Scenario: CDK Outage and Why Segmentation Mattered

In June 2024, CDK Global suffered a ransomware attack that shut down DMS access for thousands of dealers nationally. Dealerships that had already segmented their CDK traffic into a separate network zone were able to pivot to manual processes and protect adjacent systems. Dealerships that had allowed CDK's servers to sit on the same flat network as accounting and CRM found every connected system at risk. COMNEXIA's segmentation approach, VLAN isolation plus stateful firewall rules restricting DMS traffic to named IP ranges, is specifically designed to contain exactly this type of vendor-side incident.

Serving Chamblee and the Broader DeKalb County Market

COMNEXIA is headquartered in Roswell, GA, approximately 25 miles north of Chamblee via GA-400 and I-285. That proximity means on-site response to Chamblee dealerships is a realistic option for hardware failures, infrastructure projects, or compliance walkthroughs, not a multi-day wait. We currently support dealership groups across the Atlanta metro, and our technicians are familiar with the rooftop configurations common to both single-point dealers and dealer groups managing service, used-car, and new-car operations under one DeKalb County tax ID.

Get a Dealership IT Assessment

If your Chamblee dealership is approaching an FTC Safeguards Rule review, onboarding a new DMS, or simply has not had a professional audit of its CDK, Reynolds and Reynolds, or Dealertrack network configuration, call COMNEXIA at (877) 600-6550. We will schedule a documented assessment, identify gaps against 16 CFR 314.4, and deliver a prioritized remediation plan you can act on, not a sales deck.
