Cybersecurity Services in Duluth, Georgia

Cybersecurity Services for Duluth, GA Businesses

Duluth businesses operating along the Peachtree Industrial Boulevard corridor and throughout Gwinnett County face the same threat actors targeting enterprises twice their size. Ransomware groups do not skip mid-market companies, and credential-stuffing attacks hit business email accounts whether you run a 10-person accounting firm near Sugarloaf Parkway or a franchised auto dealership on Pleasant Hill Road. COMNEXIA, headquartered in Roswell, GA since 1991, delivers security-first managed IT to Duluth-area organizations that need documented, auditable protection, not a general-purpose IT contract with a security checkbox bolted on.

What Cybersecurity Actually Means for a Duluth Business

Most local breaches begin with one of three entry points: a phished employee credential, an unpatched endpoint, or a misconfigured cloud identity. COMNEXIA addresses all three with named, configured controls rather than broad promises. Every engagement starts with an asset inventory and gap assessment against a recognized framework, so your leadership sees exactly what is exposed before anything is deployed.

Endpoint Detection and Response

COMNEXIA deploys SentinelOne EDR on every managed endpoint. SentinelOne's Singularity platform uses behavioral AI to detect and autonomously roll back ransomware encryption in progress, including attacks that bypass traditional signature-based antivirus. For clients already standardized on Microsoft 365, we configure Microsoft Defender for Endpoint with attack-surface reduction rules, tamper protection enabled, and integration into Microsoft Defender for Cloud for unified alert correlation. Endpoints are enrolled through NinjaOne RMM, which pushes OS and third-party patches on a defined weekly schedule and surfaces compliance drift in monthly reports delivered to your management team.

Identity and Access Controls

Stolen passwords are the leading cause of business email compromise. COMNEXIA configures Microsoft Entra ID conditional access policies that enforce phishing-resistant MFA (Microsoft Authenticator with number matching), block legacy authentication protocols such as SMTP AUTH and Basic Auth where not operationally required, and apply named location policies so logins from outside your Duluth office network trigger step-up verification. These are not default settings. We document each policy, test it against your user population, and include configuration records in your monthly security report.

24/7 SOC Monitoring and Incident Response

Threats do not follow business hours. COMNEXIA's 24/7 Security Operations Center monitors alerts from SentinelOne and Microsoft Defender for Cloud around the clock. When a high-severity alert fires, a SOC analyst reviews it, correlates it against your environment's baseline, and initiates a response workflow rather than queueing it for morning. Clients receive documented incident timelines for every escalation, which satisfies audit and cyber-insurance carrier requirements for evidence of active monitoring.

Backup and Ransomware Recovery

Detection catches most attacks. Immutable backups recover the rest. COMNEXIA implements a 3-2-1 backup architecture: three copies of data, on two different media types, with one copy stored off-site in a geographically separate cloud region. Backups are set to immutable (write-once, cannot be deleted or encrypted by ransomware) and tested on a documented restore schedule. Recovery time and recovery point objectives are defined in writing before deployment, not estimated after an incident.

Security Awareness Training and Phishing Simulation

Technical controls fail when an employee approves a fraudulent wire transfer or enters credentials into a spoofed login page. COMNEXIA runs ongoing phishing-simulation campaigns through your Microsoft 365 tenant using Microsoft Attack Simulator, tracking click rates by department and assigning targeted remediation modules to employees who fail. Training completion rates and simulation results appear in monthly reporting, giving management a measurable risk metric rather than a certificate-of-completion screenshot.

Duluth Auto Dealerships: FTC Safeguards Rule Compliance

Gwinnett County auto dealerships using CDK Global, Reynolds and Reynolds, or Dealertrack handle nonpublic customer financial information that falls under the FTC Safeguards Rule (16 CFR 314.4), which requires a written information security program, access controls, encryption of customer data in transit and at rest, and annual risk assessments. COMNEXIA builds the required controls directly into our security stack: Entra ID conditional access restricts DMS access to authorized roles, SentinelOne monitors endpoints running CDK or Dealertrack workstations, and immutable backups protect deal jacket data. We produce the documented risk assessment the Rule requires, so your compliance file reflects actual configured controls, not a policy template.
