What Co-Managed IT Actually Means for Brookville, Ohio Businesses
Co-managed IT is not a vague partnership arrangement. It is a defined split of responsibilities between your internal IT staff and COMNEXIA, where each party owns specific tasks documented in writing before work begins. Your team keeps control of the systems and vendor relationships you know best. COMNEXIA fills the gaps: after-hours monitoring, security tooling your staff may not have time to configure correctly, patch cycles that fall through the cracks, and escalation support when an incident exceeds internal capacity. For a Brookville-area business with one or two IT generalists, that division of labor is often the difference between a manageable security posture and an exposed one.
The Security Layer Your Internal Team Gets Immediately
COMNEXIA leads every co-managed engagement with endpoint protection before touching anything else. That means deploying SentinelOne EDR on Windows and Mac endpoints and confirming active policy enforcement, not just installation. SentinelOne’s Singularity platform provides behavioral AI detection that catches fileless malware and lateral movement that signature-based antivirus misses entirely.
On the identity side, COMNEXIA configures Microsoft Entra ID conditional access policies to enforce multi-factor authentication and block legacy authentication protocols, which remain a common entry point for credential-stuffing attacks against Ohio businesses. Named location policies restrict sign-ins to approved IP ranges where operationally appropriate. These are real configuration steps inside Entra ID, not advisory recommendations.
Patch management runs through NinjaOne RMM. Patch policies are scoped by device group, operating system, and application criticality. Third-party application patching (Chrome, Adobe Reader, 7-Zip, and similar high-exposure software) runs on a separate schedule from OS updates so that a failed update in one group does not block the entire patch cycle.
How Co-Managed IT Fits Brookville Auto Dealerships
Brookville sits in Montgomery County, and the broader Miami Valley has a significant concentration of franchise auto dealerships. Any dealership using CDK Global, Reynolds and Reynolds, or Dealertrack is subject to the FTC Safeguards Rule, which requires a written information security program, access controls, continuous monitoring, and annual penetration testing as of the June 2023 enforcement date.
A co-managed model fits dealerships precisely because the DMS vendor (CDK, R&R, Dealertrack) does not manage endpoint security, and most dealership IT staff are stretched handling daily DMS issues, loaner car logistics, and F&I printer problems. COMNEXIA takes ownership of the Safeguards Rule controls that fall outside the DMS: network segmentation between the sales floor and the service bay, Microsoft Entra ID access reviews for terminated employees, and the documented incident response plan the FTC rule requires. Your IT person handles what they handle best. COMNEXIA handles what the regulation requires and your team does not have bandwidth for.
The Operational Structure: What COMNEXIA Delivers and How
Every co-managed engagement begins with a documented onboarding process that maps the existing environment before any changes are made. That includes an asset inventory via NinjaOne, a review of active directory (or Entra ID) group memberships, and a documented list of which responsibilities COMNEXIA owns versus which your team retains. Nothing is assumed.
Ongoing operations include:
- Remote monitoring and alerting: NinjaOne monitors disk health, CPU baselines, service failures, and offline endpoints 24 hours a day. Alerts route to COMNEXIA’s help desk ticketing queue with defined severity tiers.
- Help desk with ticketing: Your staff submit tickets through a branded portal or by phone. Every ticket is logged, categorized, and tracked to resolution. COMNEXIA does not drop tickets into email threads.
- Monthly reporting: Each month your designated contact receives a report showing patch compliance percentages, open and closed tickets by category, SentinelOne alert summaries, and any endpoint that fell out of policy compliance. You see exactly what happened.
- Endpoint standardization: COMNEXIA documents a baseline configuration standard for your environment and flags any device that deviates from it during the monthly review cycle.
Who Co-Managed IT Is Not Right For
If your business has no internal IT staff and no plans to hire, co-managed IT is the wrong model. Fully managed IT is the correct fit. Co-managed IT assumes you have someone internal who will own at least some tasks. COMNEXIA is explicit about this because mismatched engagements waste your money and ours.
