Cybersecurity Services in Marietta, Georgia

Cybersecurity Services for Marietta, GA Businesses

Marietta businesses face the same threat actors targeting enterprises in Midtown Atlanta, but often without a dedicated security team to respond. COMNEXIA, headquartered in Roswell, GA and serving Cobb County businesses for over 35 years, delivers security-first managed IT that goes well beyond antivirus software. We deploy, configure, and monitor real enterprise-grade controls so your staff can work without becoming the next breach headline.

What Cybersecurity Actually Means for a Marietta Business

Cybersecurity is not a product you buy once. It is a continuous set of layered controls: identity verification before any user touches company data, endpoint detection that catches behavior-based threats no signature can recognize, 24/7 monitoring that acts on alerts while your office is closed, and tested backups that survive ransomware. For a Marietta auto dealership running CDK Global, Reynolds and Reynolds, or Dealertrack, it also means documented compliance with the FTC Safeguards Rule (16 CFR 314.4), which requires a written information security program, risk assessments, employee training, and continuous monitoring of service-provider access.

Identity and Access Controls We Configure

Most breaches start with a stolen credential. COMNEXIA configures Microsoft Entra ID (formerly Azure AD) with conditional access policies that enforce multi-factor authentication on every sign-in, block logins from non-compliant devices, and restrict access by geographic location when travel is not expected. For dealership employees accessing DMS portals or customer financing records, we apply role-based access controls so a service advisor cannot reach the finance office's credit application data. These are not default settings; each conditional access policy is scoped to the specific apps and user groups in your environment.

Endpoint Detection and Response (EDR/MDR)

COMNEXIA deploys SentinelOne EDR or Microsoft Defender for Endpoint on every managed workstation and server. Both platforms use behavioral AI to detect and isolate threats that bypass traditional signature-based detection, including fileless malware and lateral movement techniques. When a threat is flagged, our 24/7 Security Operations Center (SOC) reviews the alert, confirms or dismisses it, and can remotely isolate an infected endpoint within minutes, before ransomware propagates across a dealership's network or a medical practice's patient-records server. Endpoint agents are managed through our RMM platform (NinjaOne or ConnectWise Automate), ensuring patch levels stay current and no device runs outside policy.

Backup and Recovery That Survives Ransomware

We implement a 3-2-1 backup architecture: three copies of your data, on two different media types, with one copy stored off-site in immutable cloud storage that cannot be encrypted or deleted by ransomware, even if an attacker gains administrative credentials on your network. For Marietta businesses subject to FTC Safeguards compliance or PCI DSS (which applies to any dealership processing card payments), documented and tested recovery procedures are a regulatory requirement, not optional. COMNEXIA schedules quarterly restore tests and documents the results in your monthly security report.

Security Awareness Training and Phishing Simulations

Technical controls do not stop an employee who clicks a convincing phishing link. COMNEXIA runs ongoing phishing-simulation campaigns where realistic phishing emails are sent to your staff without warning. Employees who click are immediately redirected to a brief training module. Aggregate click rates, department-level results, and trend data are included in monthly reporting, giving management a measurable view of human-layer risk. For dealerships, this directly addresses the FTC Safeguards Rule requirement for role-based security awareness training for all personnel with access to customer financial information.

Microsoft Defender for Cloud and Continuous Monitoring

For Marietta businesses running workloads in Microsoft Azure, COMNEXIA enables Microsoft Defender for Cloud to continuously assess misconfigurations, open storage buckets, and insecure API settings. Combined with 24/7 SOC monitoring, alerts generated by Defender for Cloud are triaged by a human analyst, not just logged and forgotten. This is the monitoring layer required under FTC Safeguards Rule Section 314.4(h) for detecting and responding to security events.
