Network Solutions in Roswell, Georgia

Business Network Services in Roswell, GA, Managed by COMNEXIA

COMNEXIA has designed, secured, and supported business networks from its Roswell, Georgia headquarters since 1991. Every network engagement starts with a security-first assessment, because a misconfigured switch or an open wireless SSID is as damaging as malware. If your Roswell office, retail location, or auto dealership runs on a flat, unsegmented network, you are one compromised endpoint away from a full breach. COMNEXIA fixes that with named hardware, documented configurations, and ongoing monitoring, not vague promises.

Why Roswell Businesses Need More Than a Basic Router

Fulton County businesses, from professional services firms along Alpharetta Highway to multi-rooftop dealerships across the north Atlanta metro, depend on reliable, segmented networks to stay productive and compliant. A consumer-grade router cannot enforce traffic policies, isolate guest devices, or provide the audit logs that regulators increasingly require. The FTC Safeguards Rule, which took full effect in June 2023, requires auto dealerships to implement and document network security controls including encryption, access controls, and continuous monitoring. Running CDK Global, Reynolds and Reynolds, or Dealertrack DMS traffic on the same unsegmented VLAN as your showroom guest Wi-Fi is a direct compliance gap under that rule.

What COMNEXIA Delivers for Network Infrastructure

COMNEXIA scopes, procures, configures, and manages every layer of your network. The list below reflects what we actually deploy, not a generic vendor catalogue.

• Next-generation firewalls: Fortinet FortiGate and SonicWall appliances configured with application-aware policies, intrusion prevention signatures, SSL inspection, and geo-IP filtering. FortiGate's Security Fabric integration lets us correlate firewall events with endpoint telemetry in a single dashboard.
• Business-grade wireless: Ubiquiti UniFi and Cisco Meraki access points deployed with separate SSIDs per audience, for example, one authenticated SSID on your corporate VLAN and an isolated guest SSID with bandwidth throttling and no access to internal subnets.
• VLAN segmentation: We build discrete VLANs for your DMS servers, VoIP phones, point-of-sale terminals, corporate workstations, and IoT devices such as cameras or HVAC controls. Inter-VLAN routing rules on the firewall enforce least-privilege access between segments.
• VPN and Zero Trust Network Access (ZTNA): Site-to-site IPsec tunnels for multi-location businesses and FortiClient or SonicWall's client VPN for remote workers. Where clients are adopting a zero-trust posture, we integrate ZTNA policies that verify device health and user identity before granting access to specific applications rather than the entire internal network.
• Structured cabling: Cat6A runs, patch panel labeling, and documentation of every port-to-switch mapping so that moves, adds, and changes do not become troubleshooting mysteries six months later.
• RMM-based network monitoring: Switch and firewall health, interface utilization, and configuration drift are monitored continuously through NinjaOne. Alerts route directly to our help-desk ticketing queue so nothing sits unnoticed until a user calls.

The Auto Dealership Network Scenario

A north Atlanta dealership group running three rooftops in Fulton and Cherokee counties recently needed to connect each location to a shared Reynolds and Reynolds ERA DMS instance while keeping each location's F&I workstations isolated from service-bay tablets and the customer-facing showroom Wi-Fi. COMNEXIA designed a hub-and-spoke FortiGate topology with IPsec tunnels between rooftops, dedicated VLANs for DMS traffic, F&I, service, and guest segments, and a Cisco Meraki wireless layer that pushed SSID-to-VLAN mappings via Meraki's cloud dashboard. Firewall policies allowed DMS traffic only on documented ports, and FortiGate's logging fed into our monthly reporting package. That configuration directly supports the FTC Safeguards Rule requirement for documented network segmentation between customer data systems and other network segments.

Onboarding and Ongoing Management

COMNEXIA follows a documented onboarding process for every new network client. We produce a current-state network diagram, identify undocumented devices and shadow IT access points, and deliver a written remediation plan before touching production equipment. After deployment, patch management for firewall firmware and switch operating systems runs through our NinjaOne RMM schedule. Clients receive a monthly report that includes interface utilization trends, firewall policy hit counts, patching status, and any configuration changes logged during the period. That report is not auto-generated fluff. It is reviewed by a COMNEXIA engineer before delivery.

Serving Roswell and the North Atlanta Corridor

From our office in Roswell, we support businesses throughout Fulton County and the broader north Atlanta metro, including Alpharetta, Sandy Springs, Milton, Johns Creek, and Canton. On-site response for structured cabling runs, hardware swaps, or firewall replacements does not require a long dispatch. Our team is local because our headquarters is local, and has been since 1991.
