Auto Dealer Managed IT in Brookhaven, GA

Auto Dealer Managed IT in Brookhaven, GA: Security-First Support for Dealerships

Brookhaven auto dealerships run on systems that do not tolerate downtime or breached data: a frozen CDK Global DMS terminal during a finance closing costs real money, and a misconfigured Reynolds and Reynolds integration can expose nonpublic customer financial information that triggers FTC Safeguards Rule liability under 16 CFR Part 314. COMNEXIA, headquartered in Roswell, GA since 1991, delivers managed IT designed specifically around the operational and compliance demands of metro Atlanta dealerships, including those operating in DeKalb County along Buford Highway and the Peachtree Road corridor.

Why Dealership IT Is Different From Standard Business IT

A franchise dealership connects more distinct vendor systems than almost any other small business: a DMS (CDK Global, Reynolds and Reynolds, or Dealertrack), a CRM, a desking tool, F&I document management, manufacturer OEM portals, and a service lane tablet platform can all coexist on one network. Each integration point is an attack surface. The FTC Safeguards Rule (16 CFR 314.4) requires covered dealerships to implement a written information security program, designate a qualified individual, perform a risk assessment, and report security events to their board or senior officer annually. COMNEXIA builds its managed IT scope around satisfying those specific requirements, not around a generic SMB checklist.

Network Segmentation Built for Dealership Environments

COMNEXIA engineers a dealership-specific network architecture that separates the DMS environment, the guest Wi-Fi for the showroom floor, the service lane network, and the business office into distinct VLANs enforced at the firewall. This DMZ segmentation prevents a compromised service loaner kiosk from reaching CDK or Reynolds and Reynolds data. Firewall policy rules restrict which internal hosts can initiate outbound sessions to DMS vendor cloud endpoints, reducing the blast radius of any lateral movement attempt.

Endpoint Protection and Identity Controls

Every managed endpoint at a Brookhaven dealership receives SentinelOne EDR, which provides AI-driven behavioral detection and automated rollback of ransomware encryption attempts at the kernel level, not just at the signature layer. Finance office workstations handling Dealertrack deal jackets are enrolled in Microsoft Entra ID with conditional access policies that require a compliant device state and multi-factor authentication before a session token is issued. This directly addresses the FTC Safeguards Rule requirement to control access to customer information based on the principle of least privilege.

DMS Integration and Patch Management

COMNEXIA uses NinjaOne for remote monitoring and management across all dealership endpoints. Patch cycles follow a tested deployment schedule: critical OS patches within 72 hours of release, third-party application patches within 14 days, with pre-production testing on a staged endpoint group before fleet-wide rollout. CDK Global and Reynolds and Reynolds workstations require coordination with vendor support windows because DMS software sometimes breaks after unsanctioned Windows updates. COMNEXIA maintains documented compatibility matrices for each dealership's DMS version and schedules OS patch deployment accordingly, rather than pushing patches blindly through an automated policy.

Help Desk, Onboarding, and Monthly Reporting

Every Brookhaven dealership client goes through a structured onboarding process: network discovery, asset inventory in NinjaOne, documentation of all vendor integrations and credentials, and a baseline vulnerability scan. Help-desk tickets are routed through a named ticketing system so no request disappears into email. Monthly reporting covers patch compliance percentage, open vulnerability count by severity, endpoint agent health, and any Safeguards Rule-relevant events that occurred during the billing period. That monthly report doubles as supporting documentation for the FTC's requirement that the qualified individual report to senior management on the information security program.

Scenario: CDK Global Outage Preparation for a Buford Highway Dealer

A multi-rooftop dealership group on Buford Highway learned after the June 2024 CDK Global service disruption that having no documented manual fallback process exposed them to days of lost deal flow. COMNEXIA's managed IT scope for dealerships includes a documented business continuity runbook specific to DMS unavailability: offline deal jacket templates, a backup desking process using locally cached data, and a tested failover internet circuit on a separate ISP so the finance office can still reach lenders directly through Dealertrack's web portal during a primary DMS outage.
