IT Company in Roswell, GA: Security-First Managed IT Services from COMNEXIA

COMNEXIA has operated as a Roswell-based IT company since 1991, delivering managed IT services to businesses across Fulton County and the broader metro Atlanta area. In 35 years of serving Georgia businesses, the constant pressure point we see is this: companies outgrow reactive, break-fix IT before they realize it, and the first signal is usually a security incident or a failed audit. Our model is built to get ahead of that problem with documented processes, named tools, and a security posture that is configured before anything else.

What "IT Company" Actually Means for a Roswell Business

Choosing an IT company in Roswell is not the same as choosing a software subscription. It means selecting the team that controls your patch cadence, your endpoint configuration, your user access policies, and your incident response plan. COMNEXIA functions as a fully managed IT partner: we own the outcomes, document every configuration decision, and report against measurable baselines monthly. If your current provider cannot tell you your mean-time-to-patch for critical CVEs or show you a written network diagram, that is a gap.

Security-First Infrastructure: What We Deploy and Configure

Every COMNEXIA engagement starts with a security baseline review before any service ticket is opened. We deploy and configure the following across your endpoints and identity layer:

• Remote Monitoring and Management (RMM): We use NinjaOne to monitor Windows and macOS endpoints in real time, enforce automated patch deployment within 72 hours of a critical Microsoft or third-party patch release, and generate monthly patch compliance reports by device and user group.
• Endpoint Detection and Response (EDR): SentinelOne is deployed on every managed endpoint. The Singularity platform provides behavioral AI detection, automated threat rollback, and a full attack storyline so our team can contain threats without waiting for a human to manually approve each remediation step.
• Identity and Access Management: We configure Microsoft Entra ID (formerly Azure AD) conditional access policies, including device compliance requirements, sign-in risk policies, and phishing-resistant MFA using Microsoft Authenticator or FIDO2 hardware keys. Shared admin accounts are eliminated at onboarding.
• DNS-Layer Filtering: Cisco Umbrella is configured at the DNS level to block malicious domains before a connection is established, which is particularly effective against phishing and command-and-control callbacks on unmanaged networks.
• Endpoint Standardization: All devices are enrolled in Microsoft Intune, with a baseline configuration profile enforcing BitLocker encryption, USB port restrictions, and automatic screen lock. No device joins the network outside of a documented onboarding checklist.
• Help Desk with Ticketing: All support requests route through a ConnectWise Manage ticketing system. Every ticket is logged, categorized, and tied to an asset record so we can identify recurring issues by location, device, or user before they escalate.

IT Services for Roswell Auto Dealerships: FTC Safeguards and DMS Security

Auto dealerships in the Roswell and metro Atlanta area operate under the FTC Safeguards Rule, which requires a written information security program, encryption of customer nonpublic personal information in transit and at rest, multi-factor authentication, and annual penetration testing. COMNEXIA works directly with dealerships running CDK Global, Reynolds and Reynolds, and Dealertrack DMS platforms, and we understand how each of those systems handles data egress, remote access, and user permissions.

A specific example of where IT configuration intersects with compliance: CDK Global and Reynolds and Reynolds both support role-based user access controls within the DMS, but those controls only reduce risk when paired with a properly configured identity layer at the network perimeter. COMNEXIA maps DMS user roles to corresponding Entra ID groups, enforces conditional access so that DMS access is blocked from non-compliant or unmanaged devices, and documents the full access control matrix for your Safeguards Rule records. We also configure network segmentation to isolate DMS traffic from general office traffic, which limits lateral movement if another segment is compromised.

Documented Onboarding and Monthly Reporting

Every new COMNEXIA client in Roswell goes through a structured 30-day onboarding process that includes a full asset inventory, a completed network diagram, baseline vulnerability scan results, and a written runbook documenting your environment. At the end of each month, you receive a report covering patch compliance rates by endpoint, open and closed tickets by category, any SentinelOne threat detections and their resolution, and Entra ID sign-in anomalies flagged during the period. This is not a summary PDF. It is a working document your team can use to ask specific questions.
