Co-Managed IT in Union, OH

What Co-Managed IT Means for Union, Ohio Businesses

Co-managed IT is a specific arrangement: your internal IT staff keeps ownership of the systems and projects they know best, while COMNEXIA plugs in as a senior technical layer to cover the gaps. For a Union-area business that already has one or two IT employees, this means your team is not replaced. Instead, they gain access to COMNEXIA’s security stack, tooling, and 35 years of MSP process, without the cost of hiring a full department.

This model is common in the Miami Valley for manufacturers, professional services firms, and auto dealerships that have grown past the point where a single IT generalist can manage patching, endpoint security, compliance, and helpdesk tickets simultaneously.

The Security Layer Your Internal Team Gets

COMNEXIA operates as a security-first MSP, which means every co-managed engagement begins with a documented security baseline before anything else is touched. Specific controls deployed in a co-managed arrangement include:

• Endpoint detection and response (EDR) via SentinelOne, deployed to every managed endpoint, with behavioral AI threat detection running independently of signature updates.
• Microsoft Entra ID conditional access policies configured to block legacy authentication protocols and enforce device compliance as a sign-in condition, reducing credential-based intrusion risk.
• RMM and patch management through NinjaOne, giving your internal team and COMNEXIA shared visibility into patch status across all Windows and third-party software, with automated deployment windows set to minimize business-hour disruption.
• Monthly reporting delivered as a structured summary: open vulnerabilities by severity, patch compliance rate, endpoint agent health, and any security events requiring follow-up, so your IT staff can present concrete status to ownership.

Your internal IT team retains administrative access throughout. COMNEXIA works alongside them in the same ticketing system, not around them.

Co-Managed IT for Union-Area Auto Dealerships

Dealerships in the Miami Valley running CDK Global, Reynolds and Reynolds, or Dealertrack face a compliance problem that a single in-house IT employee rarely has bandwidth to address alone: the FTC Safeguards Rule. Under the revised Safeguards Rule, dealerships that are financial institutions under the Gramm-Leach-Bliley Act must implement a written information security program covering access controls, encryption, continuous monitoring, and annual penetration testing, among other requirements.

Co-managed IT lets your dealership’s existing IT contact keep day-to-day DMS support responsibilities while COMNEXIA handles the security program components that require dedicated tooling and documentation:

• Configuring role-based access controls within Microsoft Entra ID so service advisors, F&I staff, and sales teams access only the customer financial data their role requires.
• Deploying SentinelOne EDR to the Windows workstations that touch CDK or Reynolds and Reynolds, where unmanaged endpoints are the most common ransomware entry point.
• Producing the documented risk assessment and security event log that auditors expect under the FTC Safeguards Rule.
• Monitoring network traffic for anomalous lateral movement, which is the behavior pattern seen in dealership ransomware incidents where attackers pivot from one compromised workstation toward DMS servers.

COMNEXIA has worked with dealerships as a specialty vertical for years. The FTC Safeguards compliance gap is one of the most common reasons a Union-area dealership contacts us.

The Onboarding Process (How It Actually Works)

Co-managed IT with COMNEXIA follows a documented onboarding sequence, not a vague “discovery phase.” In the first two weeks, the process includes:

1. Asset inventory and endpoint audit using NinjaOne, producing a complete list of managed and unmanaged devices, OS versions, and patch status.
2. Security baseline review, identifying gaps in MFA enrollment, conditional access configuration, and EDR coverage.
3. Ticketing integration, connecting COMNEXIA’s helpdesk to your internal system (or provisioning a shared instance) so that escalations between your team and ours are documented and traceable.
4. A written scope-of-responsibility document that defines exactly which tasks your internal IT staff owns and which COMNEXIA owns, preventing the gaps that create security incidents.

After onboarding, COMNEXIA operates as a remote-first partner. There is no local Ohio office, but the remote model is deliberate: security monitoring, patch deployment, EDR response, and helpdesk escalation do not require physical presence, and the tooling reflects that.

Who This Fits in the Miami Valley

Co-managed IT is the right model for Union businesses that have an internal IT person or small team, run 25 or more endpoints, and need documented security controls without building a full internal security department. It is not a fit for businesses that have no IT staff at all, since that situation calls for fully managed IT instead.

If your Union, Ohio business operates in auto retail, manufacturing, or professional services and your current IT setup lacks EDR coverage, structured patch management, or FTC Safeguards documentation, COMNEXIA can close those gaps without displacing your team.
