Your IT Company in Marietta, Georgia

IT Company Serving Marietta, GA Businesses Since 1991

COMNEXIA is a security-first managed IT services provider headquartered in Roswell, GA, less than 15 miles from downtown Marietta. Since 1991, we have delivered structured, documented IT management to businesses across Cobb County and metro Atlanta, including auto dealerships, professional services firms, and multi-location commercial operators. If your Marietta business runs on Windows endpoints, Microsoft 365, or dealer management systems such as CDK Global or Reynolds and Reynolds, the sections below describe exactly what we do and how we do it.

What "IT Company" Actually Means for a Marietta Business

Hiring an IT company in Marietta means getting a defined set of services delivered against a documented process, not a break-fix technician who shows up after something fails. COMNEXIA operates as a fully managed provider, which means we monitor your environment continuously using NinjaOne RMM (remote monitoring and management), push patches on a tested weekly schedule for Windows OS and third-party applications, and route every support request through a ticketed help desk so nothing falls through the cracks. Every new client goes through a written onboarding checklist that covers asset inventory, endpoint standardization, firewall rule review, and Microsoft Entra ID conditional access policy configuration before we consider the environment under active management.

Security-First Configuration: What That Looks Like in Practice

Because most breaches enter through unpatched endpoints or stolen credentials, COMNEXIA leads every engagement with a security posture review before touching anything else. Specifically, we deploy SentinelOne EDR on every managed endpoint, enforce multi-factor authentication through Microsoft Entra ID, and configure conditional access policies that block sign-ins from non-compliant devices and high-risk locations. DNS filtering is applied at the network layer to block malicious domains before a connection is established. These are not optional add-ons; they are baseline requirements for any business we manage in Marietta or anywhere in the Atlanta metro.

Auto Dealerships in Marietta: FTC Safeguards Rule Compliance

Cobb County has a significant concentration of franchised auto dealerships, and COMNEXIA has worked with dealerships running CDK Global, Reynolds and Reynolds, and Dealertrack. The FTC Safeguards Rule (updated requirements effective June 2023) requires dealerships that qualify as financial institutions under the Gramm-Leach-Bliley Act to implement a written information security program, enforce access controls, encrypt customer nonpublic personal information (NPI) in transit and at rest, conduct annual penetration testing, and maintain an incident response plan. COMNEXIA maps its managed services delivery directly to those requirements: SentinelOne covers continuous monitoring, NinjaOne RMM provides the audit-ready patch logs, and we produce a monthly security report you can hand to your compliance officer or a regulator without additional formatting work.

What COMNEXIA Delivers Month to Month

• Continuous endpoint monitoring and automated patch deployment through NinjaOne RMM, with patch compliance reports available on demand
• SentinelOne EDR installed and actively managed on every Windows and macOS endpoint in your environment
• Microsoft Entra ID conditional access policies configured to require MFA and compliant device status before granting access to Microsoft 365 applications
• Help-desk ticketing with documented resolution steps so repeat issues are identifiable and fixable at the root cause, not just closed
• Firewall and network configuration review, including segmentation of guest Wi-Fi from internal systems and DMS (dealer management system) traffic isolation where applicable
• Monthly written report covering patch status, endpoint health, open and closed tickets, and any detected threats with disposition details
• Documented onboarding process covering asset inventory, user access audit, and policy baseline before go-live

Why Marietta Businesses Hire an IT Company Rather Than DIY

Microsoft 365 licensing and Google Workspace give Marietta businesses powerful tools, but neither product configures itself securely by default. Out-of-the-box Microsoft 365 tenants ship with legacy authentication protocols enabled, no conditional access policies, and no endpoint compliance requirements. A Cobb County professional services firm running that default configuration is exposed to credential-stuffing attacks that succeed even when users have strong passwords, because legacy protocols bypass MFA entirely. COMNEXIA disables legacy authentication, enforces Entra ID conditional access, and verifies device compliance enrollment in Microsoft Intune as part of standard onboarding. That is the difference between having Microsoft 365 and having Microsoft 365 configured to hold up in an incident.
