Dealership Cybersecurity in Dunwoody, GA: Protecting Your DMS, F&I Data, and Customer Records

Auto dealerships in Dunwoody and across DeKalb County operate some of the most data-dense environments in any local industry. A single rooftop processes Social Security numbers, bank account data, and driver's license copies through DMS platforms like CDK Global, Reynolds and Reynolds, and Dealertrack, while simultaneously running F&I desks, CRM integrations, and lender portals. COMNEXIA, headquartered in Roswell, GA since 1991, delivers dealership cybersecurity programs built specifically around those systems and the federal compliance obligations that govern them.

The FTC Safeguards Rule Creates Mandatory Security Requirements for Dunwoody Dealerships

Under 16 CFR 314.4 (the FTC Safeguards Rule), auto dealerships are classified as financial institutions and must maintain a written information security program that includes access controls, encryption, continuous monitoring, and annual penetration testing, among other requirements. Non-compliance exposes your dealership to FTC enforcement action and civil liability. COMNEXIA maps every control we deploy directly to the Safeguards Rule's nine required elements, so your service records and risk assessments are audit-ready rather than assembled in a panic when a regulator calls.

Network Segmentation: Keeping Your DMS off the Same Flat Network as the Showroom Wi-Fi

A common and dangerous configuration at dealerships is a flat network where the CDK or Reynolds and Reynolds DMS server sits on the same broadcast domain as guest Wi-Fi and technician tablets on the shop floor. COMNEXIA designs and deploys a segmented DMZ architecture that isolates your DMS environment, F&I workstations, and OEM-connected service lanes into separate VLANs with firewall rules enforced at each boundary. Dealertrack portal access is further restricted by source IP and user identity, not just a password. This prevents a compromised loaner-car kiosk from becoming a pivot point into finance records.

Endpoint Detection and Response on Every Workstation and Server

COMNEXIA deploys SentinelOne EDR on every dealership endpoint, including the back-office accounting workstations that often get skipped. SentinelOne's behavioral AI detects ransomware execution patterns and rolls back malicious file changes autonomously, without waiting for a signature update. For dealerships already standardized on Microsoft 365, we layer Microsoft Defender for Endpoint to cover cloud-connected devices. Both feeds into our 24/7 SOC, which reviews alerts in real time and escalates confirmed threats to your assigned COMNEXIA engineer, not a generic queue.

Identity Controls That Stop Credential-Based Attacks on F&I and CRM Logins

Phishing emails impersonating CDK Global or RouteOne are a documented attack vector against dealerships. Once a finance manager's credentials are stolen, an attacker can pull customer credit applications directly. COMNEXIA enforces Microsoft Entra ID conditional access policies that require MFA for every login and block authentication attempts from outside approved geographic regions or unmanaged devices. Finance desk staff enroll through the Microsoft Authenticator app, and service advisors on shop-floor tablets authenticate through compliant managed devices enrolled in Microsoft Intune. No exceptions for "quick access" logins.

Backup Architecture That Meets the 3-2-1 Standard

Your DMS data, deal jackets, and scanned customer documents need a backup strategy that survives ransomware that intentionally targets connected backup drives. COMNEXIA configures immutable, off-site backups following the 3-2-1 rule: three copies, two different media types, one copy stored off-site in a cloud environment where retention policies prevent deletion for a defined period. Backup integrity is tested on a schedule documented in your monthly reporting, not assumed.

Security Awareness Training Tailored to Dealership Attack Patterns

Dealership staff turn over frequently and include roles, including lot attendants and title clerks, that rarely receive any security training. COMNEXIA runs phishing-simulation campaigns that send realistic fake emails mimicking CDK Global system alerts, Reynolds and Reynolds password reset requests, and DocuSign F&I document links. Staff who click are automatically enrolled in a short remediation module. Simulation results and completion rates appear in your monthly report so management can see exactly which departments carry the most risk.

Patch Management and RMM Covering Every Device on the Lot

COMNEXIA manages endpoints through NinjaOne RMM, which enforces patch deployment windows across all dealership workstations and servers. Critical OS and application patches are tested and pushed within 72 hours of release. Every device is inventoried, and endpoints that fall out of compliance trigger an automated alert before they become a vulnerability. Monthly reports include patch compliance rates by device and department.
