In-House IT vs. Managed IT: Real Cost Comparison for Kennesaw Businesses (2026)

In-House IT vs. Managed IT Cost in Kennesaw, GA: What Kennesaw Businesses Actually Pay

Kennesaw businesses evaluating whether to hire internal IT staff or contract a managed services provider face a decision that goes beyond a simple salary comparison. A full-time IT generalist in the Cobb County market costs roughly $55,000 to $75,000 annually in base salary alone, before benefits, PTO, and the reality that one person cannot cover evenings, weekends, or specialized security incidents. COMNEXIA, headquartered in Roswell, GA and serving metro Atlanta businesses since 1991, delivers a structured managed IT program that replaces or supplements that headcount with documented processes, named security tools, and a help desk that logs every ticket, not just the ones someone remembers to track.

What the In-House IT Cost Comparison Actually Includes

When Kennesaw companies run the numbers on in-house IT, they often count only the W-2. The real cost adds employer payroll taxes (approximately 7.65 percent FICA), health insurance contributions, hardware and software the employee needs to do the job, training to keep certifications current, and coverage gaps during vacation or turnover. A managed IT engagement with COMNEXIA bundles remote monitoring and management (RMM) through NinjaOne, endpoint detection and response via SentinelOne EDR, Microsoft 365 administration including Entra ID conditional access policy configuration, and a ticketed help desk into a per-seat monthly structure. That structure makes the monthly cost predictable and auditable in a way a single internal hire rarely is.

What COMNEXIA's Managed IT Program Delivers in Kennesaw

Every managed IT engagement starts with a documented onboarding that inventories all endpoints, maps Active Directory or Entra ID group structure, and establishes a patch management baseline. NinjaOne deploys an agent to each Windows and macOS device, enabling automated OS and third-party application patching on a defined schedule, typically within 72 hours of a critical patch release. That schedule is documented and visible in monthly reports sent to the business owner or IT decision-maker, so patch compliance is not a matter of asking an employee whether they "ran updates."

• RMM agent deployment to all managed endpoints with automated patch scheduling and compliance reporting
• SentinelOne EDR installed on every endpoint, providing behavioral detection and autonomous threat rollback without waiting for a signature update
• Microsoft Entra ID conditional access policies configured to enforce MFA and block legacy authentication protocols that bypass modern auth controls
• Help desk with a ticketing system so every request, no matter how minor, creates a timestamped record that feeds into monthly reporting
• Endpoint standardization: approved hardware configurations and software baseline to reduce variance that creates security gaps
• DNS filtering to block known malicious domains at the network layer before a payload reaches an endpoint

Auto Dealerships in Kennesaw: FTC Safeguards Rule Compliance Through Managed IT

Kennesaw sits minutes from several active dealership corridors along Barrett Parkway and US-41. Auto dealerships running CDK Global, Reynolds and Reynolds, or Dealertrack DMS platforms carry specific regulatory obligations under the FTC Safeguards Rule, which requires a written information security program, annual risk assessments, access controls, and encryption of customer nonpublic personal information (NPI) in transit and at rest. An in-house IT generalist rarely has the depth to configure CDK or Reynolds network segmentation correctly while also managing the Safeguards Rule documentation requirement. COMNEXIA's managed IT program addresses both: SentinelOne EDR and Entra ID conditional access enforce access controls at the endpoint and identity layer, while NinjaOne's reporting provides the audit trail the Safeguards Rule requires for periodic review of security controls. Dealerships get a managed IT partner that already understands DMS network architecture, not one learning it on the job.

Why Security-First Managed IT Matters for Cobb County Businesses

A security-first posture means security controls are built into the standard managed IT delivery, not sold as an upgrade tier. For a Kennesaw professional services firm or a dealership on Barrett Parkway, that means SentinelOne EDR is on every seat from day one, Entra ID conditional access blocks sign-in attempts from non-compliant devices before they reach business data, and DNS filtering runs continuously. Monthly reports show patch compliance rates, open tickets by category, and any SentinelOne alerts that required action, giving leadership a factual record rather than a verbal status update.
