Cybersecurity Services for McDonough, GA Businesses
McDonough-area businesses, from auto dealerships on Jonesboro Road to medical practices near Piedmont Henry Hospital, face the same threat actors targeting every metro Atlanta market. What differs is exposure. A Henry County dealership running CDK Global or Reynolds and Reynolds DMS software sits at a specific intersection of financial data, consumer PII, and federal compliance obligations under the FTC Safeguards Rule (16 CFR 314.4). COMNEXIA, headquartered in Roswell, GA and in operation since 1991, delivers security-first managed IT designed for exactly this risk profile.
What Cybersecurity Actually Covers for a McDonough Business
Cybersecurity is not a single product. For a business in McDonough or anywhere in Henry County, it is a layered set of controls that must work together: endpoint detection, identity protection, network segmentation, backup integrity, and staff behavior. COMNEXIA builds that stack around named, auditable platforms rather than proprietary black boxes, so you can see what is running and why.
Endpoint Detection and Response
Every managed endpoint in your environment gets SentinelOne EDR deployed and monitored by COMNEXIA's 24/7 SOC. SentinelOne uses behavioral AI to detect threats that bypass signature-based antivirus, including fileless attacks and lateral movement common in ransomware campaigns. Alerts escalate in real time to a human analyst, not a queue. For organizations already standardized on Microsoft, COMNEXIA configures Microsoft Defender for Endpoint with custom detection rules and integrates telemetry into a centralized SIEM for correlation across your Henry County environment.
Identity and Access Controls
Stolen credentials are the leading entry point in business email compromise and ransomware. COMNEXIA enforces Microsoft Entra ID conditional access policies that require multi-factor authentication on every login, block sign-ins from non-compliant devices, and flag impossible-travel events automatically. For dealerships using Dealertrack or Reynolds and Reynolds portals, these conditional access rules apply to browser-based sessions as well as native applications, closing the gap that generic MFA deployments often leave open.
FTC Safeguards Rule Compliance for Auto Dealerships
The FTC Safeguards Rule, effective June 2023 for dealers, requires a written information security program, annual risk assessments, access controls, encryption, MFA, and continuous monitoring. Non-compliance carries FTC enforcement exposure. COMNEXIA maps its standard security stack directly to 16 CFR 314.4 requirements: Entra ID MFA satisfies the authentication mandate, SentinelOne or Defender for Endpoint covers continuous monitoring of systems, and immutable off-site backups satisfy the data-recovery requirements. We document each control for your dealership principal and compliance records.
Backup Architecture That Survives Ransomware
A backup that lives on the same network as the infected machine is not a backup after a ransomware event. COMNEXIA implements a 3-2-1 architecture: three copies of data, on two different media types, with one copy stored off-site in an immutable format that cannot be encrypted or deleted by malware with domain credentials. Recovery point objectives and recovery time objectives are tested on a scheduled basis and documented in monthly reporting, so the numbers you see reflect an actual restore test, not a vendor estimate.
Phishing Simulation and Security Awareness Training
Technical controls reduce risk; trained employees stop attacks before the controls have to fire. COMNEXIA runs ongoing phishing-simulation campaigns using real-world lure templates, including vendor invoice spoofs common in the automotive supply chain, then routes employees who click into targeted microlearning modules. Completion rates and click rates are tracked per department and included in your monthly security report, giving dealership managers and Henry County business owners a measurable view of human-layer risk over time.
Patch Management and Baseline IT Hygiene
Unpatched systems are the second most common ransomware entry point after credential theft. COMNEXIA manages patching through NinjaOne RMM, with automated deployment windows configured to minimize business disruption and a documented exception process for systems that cannot be patched immediately, such as DMS workstations running legacy CDK Global components. Patch compliance rates appear in your monthly report by device group, so nothing hides in the noise.
Cloud Security Posture
If your McDonough business uses Microsoft 365 or Azure, Microsoft Defender for Cloud continuously evaluates your tenant configuration against the Microsoft Security Benchmark, surfacing misconfigurations such as open storage accounts, missing audit logging, or overprivileged service accounts before an attacker finds them. COMNEXIA reviews your secure score monthly and prioritizes remediation by actual exploitability, not just score impact.
