Co-Managed IT Services in Peachtree Corners, Georgia

Co-Managed IT Services in Peachtree Corners, GA

If your Peachtree Corners business already has an internal IT person or small team, co-managed IT fills the gaps without replacing the people you depend on. COMNEXIA, headquartered in Roswell, GA since 1991, layers enterprise-grade security controls and around-the-clock monitoring on top of your existing staff, so your IT director keeps strategic ownership while COMNEXIA handles the labor-intensive work that strains lean teams: patch cycles, endpoint hardening, after-hours incident response, and compliance documentation.

What Co-Managed IT Actually Means for a Peachtree Corners Business

Co-managed IT is a contractual split of responsibilities between your internal IT staff and COMNEXIA. You define the boundary. A common model: your IT manager owns vendor relationships, internal projects, and user onboarding, while COMNEXIA owns the RMM platform (NinjaOne), patch management policy enforcement, security event monitoring through SentinelOne EDR, and escalation response when threats are confirmed. Both sides work from a shared ticketing queue so nothing falls through on a handoff. COMNEXIA documents every configuration baseline at onboarding so your team is never locked out of their own environment.

Security Controls COMNEXIA Enforces on Your Network

COMNEXIA's co-managed model starts with a security-first posture, not a help-desk-first one. Before any ticket is opened, your environment is hardened to a documented baseline. Specific controls deployed at onboarding include:

• Microsoft Entra ID conditional access policies restricting sign-in by device compliance state and named location, blocking authentication attempts from outside the United States by default
• SentinelOne EDR installed on every managed endpoint, configured to autonomous response mode so ransomware processes are killed without waiting for a human decision
• NinjaOne RMM agent deployment with patch schedules enforced: critical OS patches applied within 14 days, third-party application patches (Chrome, Adobe, Java) within 30 days, with deviation reports delivered monthly
• Multi-factor authentication enforced through Microsoft Entra ID for all cloud applications before help-desk credentials are provisioned
• Endpoint standardization: COMNEXIA images or audits devices against a defined hardware and OS baseline, flagging end-of-life Windows 10 machines ahead of the October 2025 Microsoft support cutoff

Co-Managed IT for Peachtree Corners Auto Dealerships

Peachtree Corners sits inside Gwinnett County, one of metro Atlanta's densest auto retail corridors. Dealerships running CDK Global, Reynolds and Reynolds, or Dealertrack DMS platforms carry specific compliance obligations under the FTC Safeguards Rule, which requires a written information security program, access controls, and annual risk assessments for any business that handles consumer financial data as part of vehicle financing. COMNEXIA's co-managed model maps directly onto those requirements.

Practically, that means COMNEXIA configures network segmentation to isolate DMS traffic from general business Wi-Fi, documents user access reviews quarterly for your Safeguards Rule file, and ensures SentinelOne EDR covers the Windows-based workstations that run CDK or Reynolds and Reynolds terminals. Your internal IT contact remains the point person with the DMS vendor, but COMNEXIA owns the security layer underneath. If CDK Global pushes a software update that breaks a workstation configuration, NinjaOne alerts COMNEXIA before your service advisor notices the problem.

How Onboarding Works

COMNEXIA follows a documented onboarding sequence, not an informal kickoff call. Week one covers asset discovery using NinjaOne to produce a complete device inventory with OS versions, patch levels, and installed software. Week two covers identity audit: reviewing Microsoft 365 or Entra ID tenant for stale accounts, shared mailboxes with login enabled, and admin accounts without MFA. Week three covers policy deployment: conditional access rules, SentinelOne rollout, and patch schedule configuration. By day 30, your internal IT team receives a written baseline report showing exactly what was found and what was changed, formatted to serve as an audit artifact if your business faces a Safeguards Rule review or cyber insurance renewal questionnaire.

Monthly Reporting Your IT Manager Can Use

Every month, COMNEXIA delivers a written report covering patch compliance rates by device group, SentinelOne threat detections and dispositions, help-desk ticket volume and resolution times by category, and any devices that fell outside the hardware baseline. Your IT director uses this data to justify budget requests internally without having to pull it manually. The report is formatted so it can be attached directly to board-level security reviews or handed to a cyber insurance auditor.
