IT Services in Dunwoody, GA: Managed IT Built Around Security and Accountability

Dunwoody businesses operate in one of metro Atlanta's most competitive commercial corridors, from Perimeter Center's dense office parks along Ashford Dunwoody Road to the auto dealerships and professional service firms clustered near I-285. COMNEXIA has supported businesses across DeKalb County and the broader Atlanta region since 1991, headquartered 18 miles north in Roswell, GA. Every managed IT engagement we run starts with your security posture, not your ticket queue.

What "IT Services" Actually Means for a Dunwoody Business

Managed IT from COMNEXIA is not a help-desk subscription with a generic monitoring tool bolted on. It is a structured, documented program that begins with endpoint standardization across every Windows or macOS device in your environment, continues with automated patch cycles managed through NinjaOne, and is enforced by SentinelOne EDR running on each endpoint. SentinelOne's Singularity platform uses behavioral AI to detect and isolate threats before they propagate, which matters when your Dunwoody office shares network segments with remote workers or satellite locations across the Atlanta metro.

Identity is the second layer we lock down before we touch anything else. Microsoft Entra ID conditional access policies enforce multi-factor authentication and block sign-in attempts from non-compliant devices or risky geographic locations. For businesses already in Microsoft 365, we configure Entra ID Conditional Access alongside Defender for Business so that endpoint health status gates cloud resource access. That is a concrete security control, not a checkbox.

The Onboarding Process: Documented, Not Improvised

Every new Dunwoody client goes through a structured onboarding that produces a written network and asset inventory before we touch a single policy. We document every endpoint, server, firewall ruleset, and cloud tenant. Patch baselines are set in NinjaOne within the first two weeks, defining separate maintenance windows for servers and workstations so production systems are not rebooted mid-business-day. Help-desk tickets flow into a tracked queue with assigned ownership, and you receive a monthly report that shows patch compliance rates, open and resolved tickets by category, and any SentinelOne detections with their disposition. You see exactly what happened in your environment each month, in writing.

IT Services for Dunwoody Auto Dealerships

Perimeter-area dealerships running CDK Global, Reynolds and Reynolds, or Dealertrack depend on those dealer management systems staying online and protected. COMNEXIA has direct experience integrating managed IT around DMS environments, which means we configure firewall segmentation so DMS traffic is isolated from general office and guest Wi-Fi networks. We apply patch management exclusions that account for DMS vendor update schedules rather than overwriting them, preventing the conflict that knocks a service lane offline on a Saturday morning.

The FTC Safeguards Rule, updated with its current technical requirements effective June 2023, requires auto dealerships to maintain a written information security program, designate a qualified individual to oversee it, and implement specific technical safeguards including encryption, multi-factor authentication, and continuous monitoring. COMNEXIA's managed IT program maps directly to those controls. We provide the documented asset inventory, enforce MFA through Entra ID, and run continuous endpoint monitoring through SentinelOne, giving your qualified individual a defensible, auditable record.

Why Dunwoody Businesses Work with a Roswell-Based MSP
