Co-Managed IT Services in Dunwoody, GA: Strengthen Your Internal IT Team Without Replacing It

Dunwoody businesses along the Perimeter Center corridor, from financial firms near Hammond Drive to auto dealerships serving the I-285 interchange, frequently maintain one or two in-house IT staff who handle daily firefighting but lack the bandwidth for security hardening, patch governance, or compliance documentation. COMNEXIA's co-managed IT service plugs those gaps directly. Headquartered in Roswell, GA since 1991 and serving metro Atlanta for 35 years, COMNEXIA operates as a security-first MSP that integrates with your existing IT personnel rather than displacing them.

What Co-Managed IT Actually Means for a Dunwoody Organization

Co-managed IT is a formal, documented division of responsibilities between your internal IT staff and COMNEXIA. Before any tool is deployed, COMNEXIA conducts a structured onboarding that produces a responsibility matrix: your team owns X, COMNEXIA owns Y, and both teams share Z. That document is signed off by your IT lead and a COMNEXIA vCIO before go-live. Responsibilities are not assumed; they are written down, versioned, and reviewed quarterly.

Common splits in Dunwoody engagements include your staff managing in-person desktop support and hardware procurement while COMNEXIA owns patch management through NinjaOne, endpoint detection and response via SentinelOne EDR, Microsoft Entra ID conditional access policy configuration, and after-hours help-desk coverage through a ticketed queue. Every support interaction is logged in a ticketing platform so neither team loses context when an issue crosses ownership lines.

Security Controls COMNEXIA Brings to Your Existing Environment

Because your internal staff is already stretched, security configurations that require sustained attention are the first things that slip. COMNEXIA's co-managed model addresses this with specific, enforceable controls deployed on top of your current infrastructure:

• NinjaOne RMM with enforced patch cycles: Third-party application patches (browsers, PDF readers, Java runtimes) are deployed on a defined schedule, not left to end-user prompts. Patch compliance reports are generated monthly and shared with your IT lead.
• SentinelOne EDR on every managed endpoint: Autonomous threat detection and rollback runs without requiring your internal staff to monitor a separate console. COMNEXIA's team handles alert triage and escalation.
• Microsoft Entra ID conditional access: Sign-in risk policies, compliant device requirements, and named-location restrictions are configured and documented. MFA enforcement is verified against your full user list, not assumed.
• Endpoint standardization baseline: COMNEXIA documents your approved hardware and OS configurations so your internal tech can order and image to a known-good state without tribal knowledge.
• Monthly reporting package: Patch compliance rates, open ticket aging, endpoint health, and any SentinelOne detections are summarized in a written report delivered to your IT manager and an executive stakeholder each month.

Auto Dealerships in Dunwoody and the DeKalb County Area

Dealerships running CDK Global, Reynolds and Reynolds, or Dealertrack DMS platforms present a specific co-managed IT scenario COMNEXIA has hands-on experience with. The FTC Safeguards Rule, which took full effect for non-banking financial institutions including auto dealers in June 2023, requires a written information security program, access controls, encryption of customer data in transit and at rest, and annual penetration testing or vulnerability assessments. An internal IT coordinator at a dealership may handle day-to-day DMS support but is rarely resourced to own all of those Safeguards Rule line items simultaneously.

COMNEXIA fills that gap by taking documented ownership of specific Safeguards Rule controls. For example, COMNEXIA configures and monitors Entra ID conditional access to enforce least-privilege access to customer financial records, deploys SentinelOne on the workstations that touch CDK or Dealertrack, and produces the compliance documentation your dealer principal needs for a Safeguards Rule program review. Your internal DMS administrator continues handling Reynolds workflows and service drive operations without being pulled into security policy work.

Why Dunwoody IT Teams Choose Co-Managed Over Full Outsourcing

Full managed IT means your internal staff transitions out or shifts roles. Co-managed IT keeps your people in place with defined, expanded coverage. For Dunwoody organizations where institutional knowledge of a specific ERP, accounting platform, or DMS is embedded in one or two staff members, replacing that knowledge with a fully outsourced model creates real operational risk. COMNEXIA's co-managed structure preserves your institutional expertise and adds documented security and monitoring layers your team does not have time to maintain on their own.

Onboarding follows a written project plan with milestone checkpoints, typically spanning 30 to 60 days depending on environment size. No tools are deployed to production until the responsibility matrix is approved and your team has been trained on the shared ticketing workflow.
