Your IT Company in Snellville, Georgia

IT Company Serving Snellville, GA Businesses Since 1991

COMNEXIA is a security-first managed IT services provider headquartered in Roswell, GA, less than 30 miles from Snellville along the SR-120 corridor through Gwinnett County. Since 1991, we have designed, deployed, and managed IT infrastructure for businesses across metro Atlanta, including auto dealerships, professional services firms, and multi-site operators. If your Snellville business is running on reactive IT support, aging endpoints, or unpatched software, the sections below explain exactly what a security-first IT company engagement with COMNEXIA looks like in practice.

Why "Security-First" Is Not a Marketing Term for Snellville Businesses

Gwinnett County businesses face the same threat landscape as any metro Atlanta organization: phishing campaigns targeting Microsoft 365 credentials, ransomware delivered through unpatched Remote Desktop Protocol endpoints, and supply-chain compromises through third-party software vendors. A generic break-fix IT company responds after damage is done. COMNEXIA's model starts with the security posture before adding convenience features.

On day one of a new engagement, we deploy SentinelOne Endpoint Detection and Response (EDR) across every managed workstation and server. SentinelOne's Singularity platform performs behavioral AI analysis locally on the endpoint, meaning it can isolate a machine from the network within seconds of detecting lateral movement, even without a live connection to a cloud console. That matters for Snellville offices that lose internet connectivity during a storm on I-285 or SR-78.

What COMNEXIA Actually Delivers as Your IT Company

Managed IT with COMNEXIA is built on a documented stack, not a verbal promise. Here is the concrete service structure for Snellville clients:

• Remote Monitoring and Management (RMM): We use NinjaOne to monitor every managed endpoint 24 hours a day. NinjaOne pushes Microsoft Windows and third-party application patches on a defined schedule (critical patches within 72 hours of release, standard patches in the monthly maintenance window). Patch compliance reports are delivered monthly so you can see exactly which devices are current.
• Identity and Access Management: For businesses on Microsoft 365, we configure Microsoft Entra ID conditional access policies that block sign-in attempts from non-compliant devices and enforce phishing-resistant MFA using Microsoft Authenticator or FIDO2 hardware keys.
• Help Desk with Ticketing: Every support request opens a ticket in our platform with a logged timestamp, assigned technician, and documented resolution. There is no "we fixed it over the phone and forgot about it." Ticket history is available for compliance reviews and internal audits.
• Endpoint Standardization: New workstations are imaged and configured to a documented baseline before they reach your employees' desks. This includes disabling unnecessary local administrator rights, enforcing BitLocker drive encryption, and configuring Windows Defender Firewall rules aligned to your specific network topology.
• Documented Onboarding: Every new Snellville client receives a written network assessment, an asset inventory, and a written remediation plan with prioritized action items before we take over management. No assumptions about what is running in your environment.
• Monthly Reporting: You receive a written monthly report covering patch status, SentinelOne threat detections and resolutions, help-desk ticket volume by category, and any open risk items requiring budget decisions.

Auto Dealerships in the Snellville and Gwinnett County Area

COMNEXIA has worked with auto dealerships for decades, and the compliance and technology demands for dealers are more specific than most industries. If your dealership operates CDK Global, Reynolds and Reynolds, or Dealertrack DMS platforms, those systems require network segmentation from general office traffic, controlled access credentials, and audit-ready logging. The FTC Safeguards Rule (revised requirements effective June 2023) requires dealerships to maintain a written information security program, designate a qualified individual to oversee it, and conduct periodic risk assessments. COMNEXIA builds the technical controls that satisfy those requirements: network segmentation verified in documented firewall rules, encrypted data transmission, access controls tied to employee roles, and annual risk assessment documentation your compliance team can produce for an audit.

We configure Microsoft Entra ID so that a finance manager's credentials cannot access the service lane's DMS terminal, and vice versa. Dealertrack integrations over HTTPS are logged and monitored through our SIEM tooling. These are not general IT services bolted onto a dealership. They are dealer-specific configurations we have built and refined over 35 years.
