Co-Managed IT Services in Norcross, GA: Extend Your Internal IT Team With COMNEXIA

If your Norcross business already has an internal IT person or a small IT department, co-managed IT fills the gaps they cannot cover alone. COMNEXIA, headquartered in Roswell and serving Gwinnett County businesses since 1991, layers enterprise-grade security tooling, 24/7 monitoring, and specialized expertise on top of your existing team rather than replacing them. Your staff keeps ownership of day-to-day end-user relationships; we own the security posture, patch cadence, and escalation path they have no time to manage.

What Co-Managed IT Actually Means for a Norcross Business

Co-managed IT is a shared-responsibility model. Your internal IT administrator handles on-site hardware swaps, printer queues, and user onboarding tasks they already know. COMNEXIA takes responsibility for the pieces that require around-the-clock tooling and security expertise: remote monitoring and management (RMM) via NinjaOne, automated OS and third-party application patching, SentinelOne EDR deployed to every endpoint, Microsoft Entra ID conditional access policies, and a staffed help-desk with ConnectWise Manage ticketing for overflow and after-hours support. Neither side duplicates the other's work because we document the split in writing during a structured onboarding intake, before the first ticket is ever opened.

The Security Stack Your Internal Team Gains on Day One

Most single-person IT departments in Norcross-area small and mid-sized businesses cannot maintain a proactive security stack while also keeping the lights on. Co-managed IT through COMNEXIA deploys the following controls without requiring your team to research, license, or maintain them independently:

• SentinelOne EDR on every Windows and macOS endpoint, with autonomous threat rollback so ransomware cannot encrypt files before the agent responds.
• NinjaOne RMM for continuous endpoint visibility and automated patch deployment across Microsoft, Adobe, Chrome, and other high-risk application categories on a defined weekly schedule.
• Microsoft Entra ID conditional access configured to enforce device compliance checks and MFA before any Microsoft 365 or Azure resource is accessible, blocking credential-stuffing attempts at the policy layer.
• DNS-layer filtering to block command-and-control callbacks before malicious traffic reaches the endpoint.
• Monthly security reporting delivered to your leadership team showing patch compliance rates, open vulnerabilities by severity, and alert disposition totals your internal IT staff can review alongside COMNEXIA engineers.

Why Gwinnett County Auto Dealerships Use Co-Managed IT

Norcross sits inside a dense automotive retail corridor along Peachtree Industrial Boulevard and Jimmy Carter Boulevard. Dealerships running CDK Global, Reynolds and Reynolds, or Dealertrack DMS platforms have a specific problem: their internal IT contact is often one person managing both DMS integrations and the broader network, with no bandwidth left for the FTC Safeguards Rule compliance requirements that took full effect in June 2023.

The FTC Safeguards Rule requires dealerships to maintain a written information security program, designate a qualified individual to oversee it, conduct annual penetration testing, and monitor and log authorized user activity. COMNEXIA's co-managed model gives that internal IT contact a documented security program framework, continuous log collection from endpoints and network devices, and a named COMNEXIA engineer who can serve as the technical resource behind the dealership's designated Safeguards officer. We have hands-on experience with the network segmentation requirements that separate DMS traffic from general office traffic, which matters because CDK Global and Reynolds and Reynolds environments require specific firewall rules to function correctly after segmentation.

How the Onboarding Process Works

Co-managed IT fails when responsibilities are undefined. COMNEXIA begins every engagement with a written scope-of-work document that lists, by category, which tasks your team owns and which COMNEXIA owns. During the first two weeks we deploy NinjaOne agents to all managed endpoints, audit Active Directory or Entra ID for stale accounts and over-privileged groups, baseline your patch compliance percentage, and document any deviations from your agreed endpoint configuration standard. Your internal IT administrator receives read access to the NinjaOne and ConnectWise dashboards so they can see ticket status and device health in real time, not just in a monthly summary.

Who Co-Managed IT Is Right For in the Norcross Area

This model fits Norcross and Gwinnett County businesses that have between one and three internal IT staff members, operate more than 25 endpoints, and face compliance or security requirements their current team cannot address consistently. It also fits companies whose IT person is strong on infrastructure but has no dedicated security operations experience. If your team is handling break-fix and user support well but cannot simultaneously manage EDR alerts, patch compliance, and Entra ID governance, co-managed IT closes those gaps without a full outsourcing transition.
