Managed IT Services in Johns Creek, Georgia

Managed IT Services in Johns Creek, GA: Security-First Support from COMNEXIA

Johns Creek businesses operate in one of metro Atlanta's most competitive corridors, sharing Fulton County with a dense concentration of professional services firms, medical practices, and auto dealerships along the GA-141 and Medlock Bridge Road corridors. COMNEXIA has delivered managed IT from its Roswell, GA headquarters since 1991, meaning our engineers already know the network topology, ISP options, and compliance pressures specific to this market. If your business is running on reactive, break-fix IT, the gap between where you are and where you need to be is almost always measured in unpatched endpoints, undocumented credentials, and zero visibility into what is actually happening on your network.

What Managed IT From COMNEXIA Actually Includes

Managed IT is not a help-desk phone number bolted onto a monitoring dashboard. COMNEXIA's service stack is built around a security-first posture, meaning we harden your environment before we optimize it. Every engagement starts with a documented onboarding that maps every device, account, and data flow in your environment. That inventory drives everything that follows.

• Remote Monitoring and Management (RMM): We deploy NinjaOne as our RMM platform. Every endpoint in your Johns Creek office gets an agent that reports patch status, disk health, CPU load, and security posture in real time. Patch cycles for Windows OS and third-party applications run on a tested, scheduled cadence, not whenever someone remembers.
• Endpoint Detection and Response (EDR): SentinelOne EDR is installed on every managed workstation and server. Unlike legacy antivirus, SentinelOne uses behavioral AI to detect and automatically isolate threats before they move laterally across your network.
• Identity and Access Management: We configure Microsoft Entra ID (formerly Azure AD) with conditional access policies that enforce multi-factor authentication, block legacy authentication protocols, and restrict access by device compliance state. Shared passwords and standing admin accounts get eliminated during onboarding.
• Help Desk with Ticketing: Your staff submits tickets through a named system with documented escalation paths. Every ticket is logged, prioritized by business impact, and resolved with a written record, so you can see exactly what broke, why, and what was done to fix it.
• Monthly Reporting: Each month you receive a report showing patch compliance percentage, open and closed tickets by category, SentinelOne threat detections, and any configuration drift from your baseline. This is not a feel-good summary; it is the data you need to hold us accountable.

Why Johns Creek Auto Dealerships Need This Now

Several auto dealerships operate in and around Johns Creek, and the FTC Safeguards Rule (16 CFR Part 314), which took full effect in June 2023, imposes specific written information security program requirements on auto dealers who handle consumer financial data. That means documented access controls, continuous monitoring, incident response plans, and annual penetration testing for covered dealers. COMNEXIA works directly with dealership management systems including CDK Global, Reynolds and Reynolds, and Dealertrack. We know how those platforms store and transmit customer data, and we build our Entra ID conditional access rules and network segmentation around that architecture, not around a generic template.

A dealership running CDK Drive on a flat, unsegmented network is a Safeguards Rule violation waiting to happen. COMNEXIA's managed IT engagement includes VLAN segmentation that isolates DMS traffic from guest Wi-Fi and service lane devices, reducing the blast radius of any single compromised endpoint. This is a concrete, configurable step, not a policy checkbox.

The Onboarding Process: What Happens in the First 30 Days

Week one is discovery and documentation. We inventory every endpoint, map Active Directory or Entra ID objects, audit firewall rules, and review your current backup configuration. Week two is remediation of critical findings, including deploying SentinelOne, enabling Entra ID conditional access, and eliminating local admin rights where they are not justified. Week three is standardization, bringing every device to a documented configuration baseline managed through NinjaOne policies. Week four is the first monthly review, where we walk through the initial report with your leadership team and confirm the scope of ongoing support.
