Co-Managed IT Services in McDonough, GA: Strengthen Your Internal IT Team With COMNEXIA

McDonough and Henry County businesses that already employ an internal IT person or small IT team face a specific problem: one or two staff members cannot realistically cover patch cycles, endpoint security, 24/7 threat monitoring, compliance documentation, and day-to-day helpdesk tickets simultaneously. Co-managed IT from COMNEXIA fills those gaps precisely, without replacing your existing staff. COMNEXIA, headquartered in Roswell, GA and operating since 1991, layers its security-first platform and senior engineers directly underneath your team so critical controls do not fall through the cracks.

What Co-Managed IT Actually Means for a McDonough Business

Co-managed IT is a shared-responsibility model. Your internal IT staff retain ownership of the business processes, vendor relationships, and day-to-day user requests they already handle well. COMNEXIA takes ownership of the security and infrastructure functions that require dedicated tooling, 24/7 staffing, or specialized expertise. The split is documented in a written responsibility matrix at onboarding so neither side guesses who owns what.

Practically, that means COMNEXIA deploys and manages the RMM layer using ConnectWise Automate or NinjaOne (depending on your environment), runs automated patch cycles across Windows endpoints and third-party applications on a defined schedule, and enforces endpoint standardization baselines your internal team can audit at any time. Your IT staff log into the same dashboards, see the same ticket queue in ConnectWise Manage, and can escalate to COMNEXIA's senior engineers without opening a separate support case.

Security Controls COMNEXIA Brings to the Table

Because COMNEXIA operates as a security-first MSP, the co-managed engagement starts with closing the security gaps that understaffed internal teams most commonly leave open. Specific controls delivered in a co-managed engagement include:

• SentinelOne EDR deployed to all managed endpoints, with threat response handled by COMNEXIA when your internal team is unavailable or off-hours
• Microsoft Entra ID conditional access policies configured to enforce device compliance checks and MFA before granting access to Microsoft 365 and Azure-hosted resources
• DNS-layer filtering through a managed platform to block malicious domains before a connection is established, reducing phishing exposure without requiring endpoint intervention
• Monthly patch compliance reports delivered in writing, showing percentage of endpoints current within your defined patch window and any exceptions requiring action
• Privileged access review on a quarterly cadence, auditing local administrator rights and service account permissions across your Active Directory or Entra ID tenant

Why Auto Dealerships in Henry County Need Co-Managed IT Specifically

Several auto dealerships operate in and around McDonough along Jonesboro Road and the Highway 20 and 81 corridors. These dealerships commonly run CDK Global, Reynolds and Reynolds, or Dealertrack as their dealer management system, and each of those platforms has specific network segmentation, credential management, and logging requirements that a single in-house IT person is unlikely to maintain consistently.

The FTC Safeguards Rule, which applies to auto dealers as financial institutions under the Gramm-Leach-Bliley Act, requires documented access controls, encryption of customer nonpublic personal information, continuous monitoring, and annual risk assessments. A co-managed arrangement with COMNEXIA gives your dealership's internal IT contact the documented evidence trail that compliance requires, including written incident response procedures, access logs pulled from SentinelOne and Entra ID, and the monthly reporting your information security officer can hand to an auditor. COMNEXIA has direct experience supporting dealership environments where DMS network traffic must remain segmented from the general office network.

Onboarding and Ongoing Operations

Onboarding follows a documented process, not a freeform discovery call. COMNEXIA inventories every endpoint and server, maps Active Directory or Entra ID group structures, identifies unpatched software, and produces a written baseline report before any configuration changes are made. Your internal IT staff participate in this inventory so they see exactly what is being documented. Tooling deployment (ConnectWise Automate or NinjaOne agent, SentinelOne sensor, DNS filter) typically completes within the first two weeks. The responsibility matrix is reviewed with your team and signed off before month one ends.

After onboarding, your team has direct access to COMNEXIA engineers by phone and ticket, and monthly reporting covers patch compliance percentages, open and closed ticket volume, threat detections and outcomes, and any configuration changes made to security controls. Nothing is done silently in the background.
