Co-Managed IT in Yellow Springs, OH

What Co-Managed IT Actually Means for Yellow Springs Businesses

Co-managed IT is a specific arrangement: your internal IT staff or office manager keeps ownership of day-to-day decisions and institutional knowledge, while COMNEXIA fills defined gaps in tooling, security, and after-hours coverage. It is not a handoff. It is a documented split of responsibilities, written into a shared runbook at the start of the engagement, so nothing falls through the cracks between your team and ours.

For a Yellow Springs manufacturer, nonprofit, or auto dealership that already has one or two IT people on payroll, the problem is almost never competence. It is coverage, tooling cost, and the security-layer depth that a two-person shop cannot maintain alone.

The Security Posture COMNEXIA Brings to the Partnership

COMNEXIA is a security-first MSP with 35 years of operational history. In a co-managed engagement, we layer our security stack on top of your existing environment without displacing your team’s access or workflow.

Specific controls we deploy and manage:

• Endpoint detection and response (EDR): SentinelOne EDR deployed to every managed endpoint, with behavioral AI that detects lateral movement and fileless attacks, not just known signatures.
• Identity and access: Microsoft Entra ID conditional access policies, enforcing MFA and device-compliance checks before granting access to Microsoft 365 or Azure-hosted resources.
• Remote monitoring and management (RMM): NinjaOne or ConnectWise Automate for 24/7 endpoint visibility, automated patch deployment on a documented cadence (typically OS patches within 14 days of release, third-party patches within 30), and real-time alerting on hardware and software anomalies.
• DNS filtering: Configured at the network layer to block known malicious domains before a connection is established, reducing phishing exposure for staff on any device.

Your internal IT contact retains admin rights and full visibility inside the same RMM console. Nothing is hidden. Escalation paths are written, not verbal.

Specific Problems This Solves in the Miami Valley

Yellow Springs sits in Greene County, drawing from a Miami Valley economy that includes manufacturing, healthcare-adjacent services, small professional firms, and retail. Businesses in this corridor face the same threat landscape as any metro area, but with smaller IT budgets and less redundancy.

Co-managed IT addresses concrete gaps:

• After-hours patching and alerting without paying a full-time night-shift resource in Yellow Springs or Dayton.
• Standardized endpoint builds so that a new hire in Yellow Springs gets the same configured, hardened image as any other seat, reducing your internal IT team’s setup time to minutes rather than hours.
• Monthly reporting delivered in a format your leadership can read, showing patch compliance percentages, open ticket counts, SentinelOne threat detections, and policy exceptions, giving you audit-ready documentation.
• Help-desk ticket handling through a structured ticketing system (ConnectWise Manage), with clear tier-1 and tier-2 routing so your internal person is not fielding every password reset while also trying to manage a server migration.

The Dealership Scenario: FTC Safeguards Rule and CDK/Reynolds Environments

Auto dealerships in the Yellow Springs and greater Dayton area using CDK Global, Reynolds and Reynolds, or Dealertrack operate under the FTC Safeguards Rule (revised requirements effective June 2023), which mandates a written information security program, access controls, continuous monitoring, and annual penetration testing for financial institutions including dealerships.

A single in-house IT person at a dealership cannot realistically maintain all of these controls simultaneously. COMNEXIA’s co-managed model is built for exactly this structure. We own the continuous monitoring layer (SentinelOne telemetry, NinjaOne patch compliance, Entra ID sign-in risk logs) while your internal contact owns the DMS vendor relationship and floor-level user support.

During onboarding, we document which CDK or Reynolds modules touch cardholder or customer financial data, segment those workloads where technically feasible, and configure logging retention to satisfy the Safeguards Rule’s requirement for audit trails. Your dealership’s internal IT staff participates in the onboarding and retains full context; they are not replaced, they are reinforced.

Onboarding Process: What the First 30 Days Look Like

COMNEXIA runs a documented onboarding sequence for every co-managed engagement:

1. Asset discovery and inventory audit using NinjaOne agent deployment.
2. Shared responsibility matrix delivered in writing, specifying which tasks are COMNEXIA-owned, which are client-owned, and which require joint action.
3. SentinelOne EDR rollout to all endpoints, with policy tuned to your environment’s baseline before aggressive blocking is enabled.
4. Entra ID conditional access baseline applied to Microsoft 365 tenants.
5. First monthly report delivered at the 30-day mark, establishing the baseline metrics all future reports measure against.

COMNEXIA is remote-first. Our team serves Yellow Springs and the Miami Valley without a local Ohio office, delivering all monitoring, patching, and security management through documented remote processes.
