IT Support in Atlanta, Georgia

IT Support in Atlanta, GA: Security-First Managed IT from COMNEXIA

Atlanta businesses operate in one of the Southeast's most competitive and heavily targeted cyberthreat environments. Fulton County alone logged hundreds of ransomware and business email compromise incidents in recent years, and local organizations from Buckhead financial firms to Perimeter Center auto dealerships face daily intrusion attempts against unpatched endpoints and misconfigured cloud accounts. COMNEXIA, headquartered in Roswell, GA since 1991, delivers managed IT support built around a documented security posture first, then operational efficiency, not the other way around.

What IT Support Actually Means for an Atlanta Business

IT support is not a help-desk phone number. For a business in Atlanta, it means a continuously monitored, patched, and hardened technology stack that keeps your team productive and your data defensible. COMNEXIA structures every engagement around four measurable layers: endpoint protection, identity control, patch hygiene, and documented incident response. Every support ticket connects to one of those layers so that reactive fixes also advance your long-term security posture.

Remote Monitoring and Patch Management

COMNEXIA deploys NinjaOne as its remote monitoring and management (RMM) platform across client endpoints. NinjaOne gives our engineers real-time visibility into CPU, memory, disk health, and security-event logs for every managed Windows and macOS device at your Atlanta location. Patch cycles run on a tested schedule: Microsoft cumulative updates and third-party application patches (Chrome, Adobe, Java runtimes) are staged in a test group first, then pushed to production within 72 hours of release for critical-severity CVEs. Patch compliance reports are included in monthly business reviews so you can see exactly which devices are current and which generated exceptions.

Endpoint Security: SentinelOne EDR on Every Managed Device

Every endpoint COMNEXIA manages in the Atlanta market runs SentinelOne Singularity EDR. SentinelOne's behavioral AI engine detects and autonomously rolls back ransomware execution at the kernel level, which matters because signature-based antivirus consistently misses novel malware variants. Our standard configuration enables Threat Intelligence feeds, sets the protection policy to "Protect" mode (not "Detect" mode), and activates the Storyline feature so engineers can trace a lateral-movement chain from initial compromise to containment without manual log correlation.

Identity and Access Control via Microsoft Entra ID

Stolen credentials are the leading initial-access vector for Atlanta-area businesses. COMNEXIA configures Microsoft Entra ID (formerly Azure AD) conditional access policies that block sign-in attempts from non-compliant devices and require phishing-resistant MFA (FIDO2 keys or Microsoft Authenticator with number matching) for all admin accounts. For standard users, we apply named-location policies that flag authentication attempts originating outside Georgia and your designated remote-work states. Privileged Identity Management (PIM) is enabled for any account with global admin or Exchange admin roles, requiring just-in-time elevation with an approval workflow.

Help Desk, Ticketing, and Documented Onboarding

Support requests from your Atlanta staff route into a ConnectWise Manage ticketing queue with priority tiers tied to business impact, a down server is not the same priority level as a forgotten password. Every new client goes through a structured onboarding checklist: network diagramming, Active Directory or Entra ID audit, firewall rule review, and baseline vulnerability scan before any devices go under full management. That documentation lives in a shared IT runbook your team can reference, not locked inside COMNEXIA's internal systems alone.

IT Support for Atlanta Auto Dealerships

COMNEXIA has served auto dealerships for decades, and dealership IT support carries compliance requirements that general-purpose MSPs often miss. Dealerships running CDK Global, Reynolds and Reynolds, or Dealertrack DMS platforms depend on stable, low-latency connectivity between those DMS servers, the F&I desks, and the service lane. COMNEXIA engineers are familiar with the network segmentation requirements those platforms impose and configure VLANs to isolate DMS traffic from guest Wi-Fi and employee personal devices.

The FTC Safeguards Rule (revised effective June 9, 2023) requires dealerships to maintain a written information security program, encrypt customer nonpublic personal information in transit and at rest, and annually test security controls. COMNEXIA's managed IT support directly addresses those requirements: SentinelOne EDR satisfies the endpoint monitoring requirement, Entra ID conditional access and MFA address the access-control provisions, and our monthly patch reports and annual vulnerability assessments provide the documented testing the rule mandates. We deliver a Safeguards Rule mapping document that ties each control to the corresponding regulatory section.

Monthly Reporting and Accountability

Every Atlanta client receives a monthly report covering patch compliance percentage by device group, SentinelOne threat detections and outcomes, help-desk ticket volume by category, and any open vulnerabilities ranked by CVSS score. The report is reviewed in a scheduled call with your assigned engineer, not emailed and forgotten. If a metric falls below agreed thresholds, the call includes a remediation plan with a named owner and a target date.
