Cybersecurity Services for Union City, GA Businesses

Union City businesses along Jonesboro Road and the Camp Creek corridor face the same threat actors targeting every Atlanta-area market: ransomware groups that encrypt servers over a weekend, business email compromise scams that redirect ACH payments, and credential-stuffing attacks that exploit reused passwords. COMNEXIA has delivered security-first managed IT from its Roswell, GA headquarters since 1991, and we extend that full stack to Fulton County clients in Union City, Fairburn, and the broader southwest Atlanta corridor.

The Real Cybersecurity Risks Facing Union City Organizations

Most breaches in small-to-mid-size businesses trace back to three root causes: unpatched endpoints, absent multi-factor authentication, and no visibility into what is running on the network after hours. A single unpatched Windows vulnerability on a dealership's service-lane workstation, for example, can expose Reynolds and Reynolds or CDK Global DMS credentials to an attacker who then pivots to customer financial records. That is not a hypothetical. The FTC Safeguards Rule (16 CFR 314.4) now requires auto dealers to maintain a written information security program, designate a qualified individual, and document access controls, risk assessments, and employee training, with penalties for non-compliance enforceable by the FTC.

What COMNEXIA Delivers: Named Controls, Not Vague Promises

Every Union City engagement is built around a defined security baseline. We do not describe our work in general terms; we configure specific platforms and document every change. Here is the core stack we deploy and manage:

• Endpoint Detection and Response (EDR/MDR): We deploy SentinelOne EDR on every managed endpoint. SentinelOne's Singularity platform uses behavioral AI to detect and autonomously roll back ransomware before encryption completes, a capability signature-based antivirus cannot match. For Microsoft-centric environments we integrate Microsoft Defender for Endpoint in P2 licensing with custom detection rules tuned to your environment.
• Identity and Access Control: We configure Microsoft Entra ID (formerly Azure AD) conditional access policies that enforce MFA on every sign-in, block authentication from non-compliant devices, and apply named location restrictions so that a login attempt from outside Georgia triggers a step-up challenge or an outright block.
• 24/7 SOC Monitoring: Alerts from SentinelOne and Microsoft Defender for Cloud feed into a security operations center staffed around the clock. When a threat is confirmed, the SOC isolates the affected endpoint automatically and notifies your designated contact, not just your IT inbox.
• Immutable, Off-Site Backup (3-2-1 Architecture): We implement three copies of data on two different media types, with one copy stored off-site and written to immutable storage that ransomware cannot encrypt or delete. Recovery from immutable backup is the last line of defense when every other control fails.
• Patch Management via NinjaOne RMM: NinjaOne deploys OS and third-party application patches on a defined schedule, with a separate ring for testing critical patches before broad rollout. Every endpoint shows a live compliance score visible in your monthly report.
• Phishing-Simulation Security Awareness Training: We run recurring phishing simulations against your employee list and automatically enroll users who click into short remediation training modules. Dealerships using Dealertrack or CDK Global portals are frequent phishing targets because attackers know those portals hold customer PII and payment data.
• PCI DSS and FTC Safeguards Alignment: For Union City businesses that process card payments or hold consumer financial data, we map your controls to PCI DSS requirements and the FTC Safeguards Rule's nine required program elements, producing documented evidence for auditors or regulatory review.

Auto Dealerships in the Union City Area: A Specific Use Case

A franchised dealership running CDK Global or Reynolds and Reynolds has a uniquely complex attack surface: service-lane tablets, F&I office workstations, a parts inventory system, and customer-facing Wi-Fi all on the same network segment if segmentation is not enforced. COMNEXIA builds VLAN-based network segmentation so that a compromised service-lane device cannot reach the DMS server. We enforce Entra ID conditional access so that F&I staff can access Dealertrack only from managed, compliant devices. We document the annual risk assessment that 16 CFR 314.4(b) requires and produce the written incident response plan that the rule mandates. Dealerships that have been through an FTC audit know that documentation is as important as the controls themselves.

Onboarding Process: What Happens After You Call

COMNEXIA's onboarding follows a documented 30-day process. Week one is discovery: we inventory every endpoint, map your Active Directory or Entra ID tenant, and identify unpatched systems and open ports. Week two, we deploy SentinelOne and NinjaOne agents and begin enforcing MFA through Entra ID conditional access. Weeks three and four address backup configuration, network segmentation review, and your first phishing simulation baseline. You receive a written security posture report at day 30 that names every gap we found and every control we closed.
