Co-Managed IT Services in Atlanta, GA: Structured Support for Internal IT Teams

If your Atlanta business already employs one or more IT staff members but needs deeper security controls, after-hours coverage, or specialized expertise your team lacks, co-managed IT is the correct engagement model. COMNEXIA, headquartered in Roswell, GA since 1991, partners with internal IT departments across Fulton County and metro Atlanta, filling defined gaps rather than replacing the people you already trust. This is not a hand-off. It is a structured overlay where each party owns a documented scope.

What Co-Managed IT Actually Means in Practice

In a co-managed arrangement, COMNEXIA and your internal IT team operate from a shared service matrix. Before go-live, both sides sign off on a responsibility assignment document that specifies who patches, who responds to endpoint alerts, who owns identity governance, and who manages vendor escalations. Nothing is assumed. This prevents the coverage gaps that create security incidents when two teams each believe the other handled a critical update.

COMNEXIA deploys NinjaOne as the RMM platform, giving your internal team full visibility into the same dashboard we monitor. Your IT administrator can suppress alerts, push scripts, or escalate tickets without going through us. If your team prefers ConnectWise Automate because it is already in your environment, we can integrate into that instance instead. Either way, patch cycles run on a defined cadence: Windows and third-party patches assessed weekly, critical patches deployed within 72 hours of vendor release, and a monthly patch compliance report delivered to your IT lead in writing.

Security Controls COMNEXIA Manages in a Co-Managed Engagement

Because COMNEXIA operates as a security-first MSP, the security layer is where we most commonly extend internal teams. Specific controls we configure and monitor in co-managed engagements include:

• SentinelOne EDR deployed to every managed endpoint, with automated threat response policies set to quarantine on detection so your internal team is not required to be on-call at 2 a.m. for an active incident.
• Microsoft Entra ID conditional access policies scoped by user role, device compliance state, and named location, preventing credential-only authentication from unmanaged devices outside your defined Atlanta office networks.
• Microsoft Defender for Business or Defender for Endpoint (Plan 2, depending on your Microsoft 365 licensing tier) configured with custom detection rules aligned to your industry's common attack vectors.
• DNS-layer filtering through a managed policy, blocking command-and-control callback domains before a payload executes.
• Multi-factor authentication enforcement across Microsoft 365 and any federated SaaS applications, with Authenticator app push notifications as the required second factor, not SMS.

Your internal IT staff retains administrative credentials and can modify configurations with documented change-control approval. COMNEXIA receives alerting on any policy change that weakens a security baseline, which keeps your security posture auditable even when your team makes day-to-day adjustments.

Co-Managed IT for Atlanta-Area Auto Dealerships

Automotive dealerships operating in the Atlanta metro area face a specific compliance requirement: the FTC Safeguards Rule (16 CFR Part 314), which mandates a written information security program, access controls, continuous monitoring, and annual penetration testing for non-bank financial institutions, including franchised dealers. Dealerships running CDK Global, Reynolds and Reynolds, or Dealertrack DMS platforms often have a dedicated IT coordinator or office manager handling day-to-day system access, but that person is rarely equipped to configure SentinelOne response policies, manage Entra ID conditional access, or produce the annual risk assessment the Safeguards Rule requires.

COMNEXIA closes that gap. We have worked with dealerships using all three of those DMS platforms. We know which CDK Global ports require firewall whitelisting, how Reynolds and Reynolds ERA-IGNITE communicates with the dealer network, and what Dealertrack's hosted environment expects for single sign-on federation. Your internal coordinator continues owning user onboarding and floor-level troubleshooting. We own the security stack, the Safeguards Rule documentation, and the after-hours monitoring your coordinator cannot staff.

Help Desk, Ticketing, and Monthly Reporting

COMNEXIA operates a staffed help desk reachable by phone and ticketing portal. In a co-managed model, we configure ticket routing rules so that your internal IT staff receives first assignment on issues within their documented scope, with automatic escalation to COMNEXIA if the ticket ages past your agreed threshold. Ticket data, endpoint health, patch compliance percentages, and open vulnerability counts are compiled into a monthly report delivered to your IT director or department head. That report is formatted to feed directly into a board-level or ownership-level IT review, not a technical summary that sits unread in an inbox.

Onboarding Process for Atlanta Businesses

COMNEXIA's onboarding begins with a network and endpoint discovery scan, asset inventory reconciliation against your existing records, and a gap analysis against your current security baseline. We document findings before touching any configuration. Internal IT staff are included in every onboarding call so they understand what is being deployed and why. Full onboarding for a 50-seat environment typically completes within 30 days.
