Dealership IT Services in Marietta, GA: Managed Security and Compliance for Auto Dealers

Auto dealerships in Marietta and across Cobb County operate some of the most complex IT environments in any industry. A single rooftop runs CDK Global, Reynolds and Reynolds, or Dealertrack as its dealer management system (DMS), plus a separate CRM, a financing and insurance (F&I) platform, manufacturer portals, and a service lane with its own wireless infrastructure. COMNEXIA has supported Georgia dealerships since 1991 from its Roswell headquarters, and every engagement starts with the same foundation: locking down the network before optimizing anything else.

Why Dealership IT Is Not Generic IT

The FTC Safeguards Rule (16 CFR 314.4) classifies auto dealers as financial institutions because they originate and broker consumer credit. That classification requires a written information security program, a qualified individual overseeing it, risk assessments, access controls, continuous monitoring, and an incident response plan. Non-compliance can trigger FTC enforcement, not just a warning letter. A managed IT provider that handles offices and restaurants but has never configured a CDK Global or Reynolds and Reynolds environment cannot satisfy those requirements efficiently, because the integrations, data flows, and network segments in a dealership are specific to the automotive retail stack.

Network Architecture: DMZ and DMS Segmentation

COMNEXIA engineers a multi-zone network for Marietta dealerships that physically and logically separates the DMS from the customer Wi-Fi, the service department, the sales floor, and any manufacturer telematics feed. A proper dealership DMZ places the CDK or Reynolds and Reynolds DMS server (or cloud connector) in an isolated segment with firewall rules that allow only the ports and protocols those platforms require. F&I workstations communicate with the DMS over a documented, monitored internal path rather than through a flat network where a compromised sales laptop can reach deal jackets. VLANs are assigned per function, with inter-VLAN routing rules enforced on a managed firewall (typically Fortinet FortiGate) configured with application-layer inspection for DMS traffic signatures.

Endpoint Security Across the Dealership Floor

Every managed endpoint at a Marietta dealership runs SentinelOne EDR for behavioral threat detection. Unlike signature-based antivirus, SentinelOne identifies and isolates a compromised F&I workstation in real time without waiting for a definition update. Microsoft Entra ID (formerly Azure AD) conditional access policies enforce multi-factor authentication for any employee accessing Dealertrack or a manufacturer portal, and restrict sign-in to compliant, managed devices only. Unmanaged personal phones cannot authenticate to dealership systems regardless of correct credentials. Patch management runs through NinjaOne, which applies operating system and third-party patches on a tested schedule that accounts for DMS vendor maintenance windows so a CDK update and a Windows patch do not collide and break a critical process.

What COMNEXIA Delivers for Marietta Dealerships

• FTC Safeguards Rule gap assessment mapped to 16 CFR 314.4 requirements, with a written remediation plan and documented risk assessment on delivery
• DMS-aware network segmentation for CDK Global, Reynolds and Reynolds, and Dealertrack environments, including firewall rule documentation
• SentinelOne EDR deployment and management on all Windows and Mac endpoints across sales, service, and F&I
• Microsoft Entra ID conditional access configuration enforcing MFA and device compliance before any cloud or DMS portal access
• NinjaOne-driven patch management with dealer-specific maintenance windows to avoid conflicts with DMS vendor update cycles
• Help desk with a ticketing system (tracked in ConnectWise Manage) so every service request has a ticket number, an assigned technician, and a documented resolution, not a text to someone's cell phone
• Monthly reporting that shows patch compliance percentage, open vulnerabilities, endpoint health, and ticket volume by department so the dealer principal or office manager can review actual data
• Secure integration review for third-party F&I tools and CRM platforms connecting to the DMS, confirming that data paths are encrypted and that API credentials are rotated on a documented schedule

A Concrete Example: F&I Workstation Isolation

A Marietta Chevrolet store using Dealertrack for F&I had all finance workstations on the same flat network as the showroom floor. A phishing email opened on a salesperson's machine gave an attacker lateral movement access to the finance office. COMNEXIA's approach places F&I workstations on a dedicated VLAN, blocks inter-VLAN traffic except for the specific Dealertrack application ports (443 outbound, documented source IPs), and routes all F&I printing through a dedicated print server rather than shared network printers accessible from the sales floor. SentinelOne on the finance workstations provides a second layer of containment if a threat does reach that segment.
