Auto Dealer Managed IT in Decatur, GA

Auto Dealer Managed IT in Decatur, GA | COMNEXIA

Security-First IT Management Built for DeKalb County Dealerships

Auto dealerships in Decatur and the surrounding DeKalb County market run on systems that carry sensitive consumer financial data around the clock. CDK Global, Reynolds and Reynolds, and Dealertrack dealer management systems (DMS) process credit applications, vehicle titles, and F&I contracts continuously, making a dealership's network one of the highest-risk environments a managed IT provider can take on. COMNEXIA has served Georgia auto dealerships from its Roswell, GA headquarters since 1991, and every engagement starts with the security posture, not the help desk ticket count.

FTC Safeguards Rule Compliance Is Not Optional

The FTC Safeguards Rule (16 CFR Part 314) requires auto dealers who are financial institutions under the Gramm-Leach-Bliley Act to maintain a written information security program, designate a qualified individual to oversee it, and implement specific technical safeguards including encryption of customer data in transit and at rest, multifactor authentication, and annual penetration testing. Dealers that process nonpublic personal information through their DMS, CRM, or F&I tools are directly covered. COMNEXIA builds the technical controls required by 314.4 into every dealership managed IT engagement, including network segmentation of the DMS environment, continuous monitoring, and documented incident response procedures that satisfy the Rule's reporting obligations.

DMS and F&I Integration Done Securely

Connecting a CDK Global or Reynolds and Reynolds DMS to third-party F&I tools, CRM platforms, and lender portals creates integration points that are common targets for credential theft and data exfiltration. COMNEXIA engineers configure a documented network DMZ that isolates DMS traffic from general office and guest Wi-Fi segments. Dealertrack integrations with RouteOne or dealer-specific lender feeds are routed through monitored, firewalled paths rather than flat networks. Microsoft Entra ID conditional access policies enforce device compliance checks before any user can authenticate to integrated cloud services, blocking unmanaged personal devices from reaching F&I data even when credentials are valid.

Endpoint and Server Management Across the Dealership Floor

A typical Decatur dealership runs a mix of service-lane tablets, finance office workstations, showroom kiosks, and back-office servers. COMNEXIA standardizes and manages every endpoint through NinjaOne RMM, which delivers automated patch deployment for Windows OS and third-party applications, real-time device health visibility, and scripted remediation without requiring a technician on-site. SentinelOne EDR runs on every managed endpoint, providing behavioral AI-based threat detection that does not rely on daily signature updates, which matters in a dealership environment where a service-lane device may not reboot for days. Monthly reporting delivered to the dealer principal covers patch compliance rates, detected threats, and open vulnerabilities by device.

What COMNEXIA Delivers for Decatur Dealers

• Documented network segmentation separating DMS, F&I, service, and guest traffic, implemented with VLAN tagging and firewall rules reviewed against FTC Safeguards Rule 314.4(d) requirements
• NinjaOne RMM deployment covering patch management, remote monitoring, and automated alerting for every managed Windows endpoint and server
• SentinelOne EDR on all endpoints, with policies configured to isolate a compromised device from the network without waiting for technician intervention
• Microsoft Entra ID conditional access configured to require MFA and device compliance before granting access to Microsoft 365 and any cloud-connected DMS or CRM portal
• Structured onboarding that documents every device, user account, software license, and third-party vendor integration before day-one coverage begins
• Help-desk ticketing through a named system with ticket histories visible to dealer management, covering break-fix requests from service writers, finance managers, and GSMs
• Monthly written reporting covering security events, patch status, and any open items requiring dealer principal decisions

A Realistic Scenario for a Decatur Dealership

A franchise dealer on Candler Road running Reynolds and Reynolds ERA-IGNITE notices that a service advisor's workstation is flagging on the DMS server for unusual query volume late on a Friday night. Because COMNEXIA has segmented the DMS VLAN and deployed SentinelOne, the RMM alert surfaces within minutes and SentinelOne can isolate that endpoint automatically while the dealership's data remains contained to the segmented DMS network. Without segmentation, that same activity on a flat network could allow lateral movement to the finance office servers before anyone notices.
