Your IT Company in Dunwoody, Georgia

IT Company Serving Dunwoody, GA Businesses: Managed IT Services from COMNEXIA

Dunwoody sits at the intersection of Perimeter Center commerce and DeKalb County's growing business corridor, hosting regional offices, professional services firms, and auto dealerships that depend on always-on infrastructure. COMNEXIA, headquartered in Roswell, GA since 1991, delivers security-first managed IT to Dunwoody businesses that need more than a break-fix vendor. We operate as your full-scope IT company, covering endpoint protection, network management, compliance, and help-desk support under one documented, accountable engagement.

What "IT Company" Actually Means for a Dunwoody Business

Hiring an IT company is not the same as buying a software subscription. A genuine managed IT relationship means COMNEXIA owns the outcome: we assess your current environment during a structured onboarding, document every asset in our RMM platform (NinjaOne), deploy consistent endpoint configurations, and maintain a ticketed help-desk so every request has an owner and a resolution timestamp. Monthly reports show patch compliance rates, open vs. closed tickets, and any policy exceptions, giving your leadership team a factual picture of IT health rather than an anecdotal one.

Security-First Posture: The Starting Point, Not an Add-On

Every COMNEXIA engagement begins with hardening before we touch anything else. For Dunwoody clients running Microsoft 365, that means enabling Microsoft Entra ID conditional access policies to block authentication from non-compliant or unrecognized devices, enforcing phishing-resistant MFA (FIDO2 or Microsoft Authenticator number-matching), and configuring Microsoft Defender for Business with custom detection rules. On the endpoint layer, we deploy SentinelOne EDR with autonomous threat response enabled, so a ransomware detonation triggers an automatic isolation of the affected machine without waiting for a human to approve the action.

Patch management runs through NinjaOne on a defined cycle: critical OS patches within 72 hours of release, third-party application patches (Chrome, Adobe, Java) within 14 days, and documented exceptions for any system that cannot patch without vendor approval. This schedule is not aspirational. It is written into your service agreement and visible in your monthly compliance report.

Auto Dealerships in the Perimeter Area: CDK, Reynolds and Reynolds, and FTC Safeguards Compliance

Dunwoody and the surrounding Perimeter Market area include franchise dealerships operating dealer management systems from CDK Global, Reynolds and Reynolds, and Dealertrack. These platforms handle non-public customer financial data, making FTC Safeguards Rule compliance (16 CFR Part 314, updated requirements effective June 2023) a legal obligation, not a best practice. COMNEXIA has direct experience configuring network segmentation that isolates DMS traffic from general office traffic, implementing role-based access controls so service-lane staff cannot reach F&I data, and producing the annual risk assessment documentation the Safeguards Rule requires in writing.

If your Dunwoody dealership uses CDK Drive or Reynolds ERA, COMNEXIA coordinates directly with those vendors on supported configurations rather than applying generic firewall rules that break DMS integrations. We also enforce MFA at the DMS login level where the platform supports it, and log all privileged access for the minimum six-month retention the Safeguards Rule specifies.

What COMNEXIA Delivers: Specific Services, Not a Services List

• Documented onboarding: Full network discovery, asset inventory in NinjaOne, baseline configuration snapshot, and a written gap report delivered within the first 30 days.
• Endpoint standardization: SentinelOne EDR on every managed device, Windows Autopilot or manual imaging to a hardened SOE (Standard Operating Environment), and automated software inventory audits monthly.
• Microsoft 365 administration: Entra ID conditional access, Intune device compliance policies, Exchange Online mail-flow rules for anti-phishing, and Defender for Business alert triage included in the base engagement.
• Help-desk with ticketing: Every request logged in ConnectWise Manage, prioritized by severity, and assigned to a named technician. Dunwoody clients receive the same ticketing visibility as any other market we serve.
• Patch management: NinjaOne-automated patching on the defined schedule above, with a monthly patch compliance report showing percentage patched, exceptions, and remediation notes.
• Monthly business review data: Uptime statistics, ticket volume by category, patch compliance percentage, and any open security findings, formatted for a non-technical owner or office manager.

Why Dunwoody Businesses Choose a Local-Rooted IT Company

COMNEXIA has operated in the metro Atlanta market for 35 years, which means our technicians are familiar with the fiber and coax infrastructure providers serving Perimeter Center, the building management constraints in Dunwoody's Class A office towers, and the compliance environment specific to Georgia-based financial services and automotive retailers. We are not a national franchise applying a generic playbook. When a Dunwoody client has a network failure at 7 a.m. before a sales floor opens, our escalation path is a team that already knows the environment because we documented it on day one.
