Co-Managed IT Services in Marietta, Georgia

Co-Managed IT Services in Marietta, GA: COMNEXIA Partners With Your In-House IT Team

Many Marietta businesses have an internal IT person or small IT department that handles day-to-day requests well but runs thin when a ransomware alert fires at 2 a.m., a CDK Global DMS integration breaks during a Saturday sales push, or a Windows patch cycle conflicts with production software. Co-managed IT from COMNEXIA fills exactly those gaps. Rather than replacing your team, COMNEXIA operates as a security-first extension of it, contributing enterprise-grade tooling, 24/7 monitoring depth, and 35 years of Cobb County and metro Atlanta institutional knowledge your internal staff cannot replicate on its own.

What Co-Managed IT Actually Means for a Marietta Business

Co-managed IT is a formal, documented split of IT responsibilities between your in-house staff and COMNEXIA. Before any work begins, both sides sign a Responsibility Assignment Matrix (RACI) that specifies, line by line, who owns patch approval, who handles Level 1 helpdesk tickets, who manages firewall rule changes, and who holds vendor escalation credentials. Nothing is assumed. Your technician keeps the functions where your institutional knowledge is strongest. COMNEXIA shoulders the security-heavy and after-hours workloads where coverage gaps are costliest.

The Security Layer Your Internal Team Gains Immediately

COMNEXIA's security-first posture means the co-managed engagement is built on a hardened baseline before routine support tasks are even scheduled. Specifically, every co-managed client receives:

• SentinelOne EDR deployed to all Windows and macOS endpoints, with COMNEXIA's SOC reviewing autonomous threat detections and escalating confirmed incidents to your team with remediation steps already drafted.
• Microsoft Entra ID Conditional Access policies configured to require compliant devices and MFA for every cloud application, including Microsoft 365 tenants common in Marietta dealership groups and professional services firms.
• RMM coverage through NinjaOne, giving COMNEXIA real-time visibility into patch status, disk health, and agent connectivity across every managed endpoint, whether your staff is on-site or remote.
• Monthly patching cycles on a published schedule: third-party application patches (Chrome, Adobe Acrobat, Java runtimes) are tested and deployed within 14 days of release, and Microsoft cumulative updates follow your approved change window.
• DNS-layer filtering via a vetted secure DNS resolver that blocks command-and-control callbacks before malware can phone home, a control specifically relevant to dealership networks running Reynolds and Reynolds ERA or Dealertrack integrations where lateral movement risk is high.

Co-Managed IT for Marietta Auto Dealerships: FTC Safeguards Compliance

Auto dealerships in Marietta operating under the FTC Safeguards Rule (16 CFR Part 314, fully enforced since June 2023) must maintain a written information security program, designate a qualified individual to oversee it, and produce annual reports to their board or senior management. Many dealerships have a single IT generalist who manages DMS workstations and printer queues but lacks the bandwidth to own Safeguards documentation, conduct annual risk assessments, or monitor access logs for CDK Global or Reynolds and Reynolds environments.

COMNEXIA's co-managed model directly addresses this. COMNEXIA handles the annual risk assessment documentation, maintains the asset inventory required under Safeguards, and provides the written monthly monitoring reports your designated Qualified Individual can present to ownership. Your internal IT contact stays focused on floor operations while COMNEXIA supplies the compliance infrastructure. This is not generic compliance consulting; it is hands-on configuration of access controls, encryption settings for customer nonpublic personal information (NPI), and log retention policies inside the actual DMS and network environment your store runs today.

Helpdesk Tiering and Ticket Ownership in a Co-Managed Model

Ticket routing in a co-managed engagement follows a pre-agreed tiering structure loaded into a shared ticketing platform so neither team duplicates effort or drops requests. Level 1 and Level 2 tickets (password resets, workstation connectivity, peripheral setup) can be routed to your internal staff during business hours. COMNEXIA's helpdesk picks up overflow, after-hours, and all security-classified tickets regardless of time. Every ticket closes with documented resolution notes your internal technician can reference, building a searchable knowledge base specific to your Marietta environment over time.

Onboarding Process for Marietta Co-Managed Clients

COMNEXIA's onboarding follows a documented 30-day process: network discovery and asset inventory in week one, RMM agent and SentinelOne deployment in week two, Conditional Access policy review and Entra ID audit in week three, and a formal handoff call with your internal IT lead in week four to finalize the RACI and establish escalation contacts. No assumptions about your existing environment are made before discovery is complete.

Why Marietta Businesses Work With COMNEXIA

COMNEXIA has operated continuously out of Roswell, GA since 1991 and maintains active client relationships across Cobb County, including businesses on the Barrett Parkway corridor and near the Marietta Square. That proximity means an engineer familiar with your network can be on-site in Cobb County without a multi-hour dispatch window when a hands-on issue demands it.

If your Marietta IT team is stretched across too many priorities to maintain the security posture your business now requires, call COMNEXIA at (877) 600-6550 to schedule a no-obligation co-managed IT assessment. COMNEXIA will review your current coverage gaps, your existing tooling, and your compliance obligations before recommending a specific responsibility split, not a package that ignores what your team already does well.
