Network Solutions in Sandy Springs, Georgia

Network Services for Sandy Springs Businesses | COMNEXIA Managed IT

Sandy Springs businesses running on weak or unmanaged networks face a specific set of risks: unpatched switches that expose internal traffic, flat network architectures that let a single compromised device reach every other system, and business-grade wireless that was installed once and never segmented. COMNEXIA has delivered managed network infrastructure to metro Atlanta businesses since 1991, operating out of Roswell, GA, roughly six miles from Sandy Springs along GA-400. Our engineers configure, monitor, and maintain the physical and logical network layer so your operations stay connected and your data stays contained.

Why Network Architecture Is a Security Decision First

A misconfigured network is not just an IT inconvenience. It is an open path for ransomware to move laterally from a receptionist workstation to a server room. COMNEXIA treats every network engagement as a security project before it is an infrastructure project. That means the firewall policy, VLAN layout, and remote-access controls are designed together rather than bolted on after the fact.

For Sandy Springs businesses subject to the FTC Safeguards Rule, including franchise auto dealerships using CDK Global, Reynolds and Reynolds, or Dealertrack DMS platforms, this matters directly. The Safeguards Rule requires dealers to implement network segmentation and access controls as part of a written information security plan. A flat network where DMS terminals share a broadcast domain with guest Wi-Fi is a compliance failure, not just a configuration preference.

What COMNEXIA Delivers for Sandy Springs Networks

• Next-generation firewall deployment and management: COMNEXIA installs and manages Fortinet FortiGate and SonicWall next-gen firewalls with application-aware policies, intrusion prevention signatures, and SSL inspection enabled. Firewall rulesets are reviewed quarterly and logged to a central SIEM for audit trail continuity.
• VLAN segmentation: Your guest Wi-Fi, point-of-sale terminals, VoIP phones, and corporate workstations operate on separate VLANs with inter-VLAN routing controlled at the firewall layer. At a dealership, this means CDK or Reynolds and Reynolds DMS traffic is isolated from the showroom customer network and the service loaner device pool.
• Business Wi-Fi with Ubiquiti UniFi and Cisco Meraki: COMNEXIA sizes and positions access points based on a site walk, not a floor plan estimate. UniFi deployments use the UniFi Network controller for centralized SSID management, band steering, and per-SSID VLAN assignment. Cisco Meraki deployments include cloud-managed visibility with automatic RF optimization and per-client traffic analytics.
• VPN and Zero Trust Network Access (ZTNA): Remote employees and service vendors connect through site-to-site VPN tunnels or ZTNA policies that verify device posture before granting access to internal resources. We configure Fortinet's FortiClient with endpoint compliance checks rather than issuing blanket VPN credentials.
• Structured cabling: Patch panels, cable runs, and switch closets are documented with port-to-device mapping so that any technician, including yours, can trace a connection without guesswork. We follow TIA-568 standards for Cat6 runs and label every patch panel port at installation.

Ongoing Network Monitoring and Management

After installation, your network is enrolled in COMNEXIA's RMM platform, NinjaOne, which monitors switch port status, firewall CPU and memory, and interface error rates in real time. Firmware updates for managed network devices are tested in a staging environment and pushed during approved maintenance windows, not reactively after a breach. Monthly reports delivered to your IT contact show bandwidth utilization by VLAN, firewall policy hit counts, and any devices that missed a patch cycle.

Help-desk tickets tied to network issues, a slow VPN connection, an access point that stopped broadcasting, a firewall policy blocking a vendor application, are routed through a structured ticketing system. Every ticket is logged with a timestamp, assigned engineer, and resolution note so you have a full service record, not a conversation thread in someone's inbox.

The Dealership Network Scenario

A Sandy Springs-area franchise dealership running Dealertrack on a single flat network with shared Wi-Fi credentials for staff and customers is out of alignment with FTC Safeguards Rule requirements effective June 2023. COMNEXIA's remediation process starts with a network diagram of existing infrastructure, identifies all devices touching NPI (nonpublic personal information), segments DMS traffic to an isolated VLAN behind a FortiGate firewall policy, places customer Wi-Fi on a separate SSID with a captive portal, and documents the full configuration change in a format your compliance officer can attach to your written information security plan.

Start with a Network Assessment

If you do not have a current network diagram, documented firewall policy, or VLAN map, that is the starting point. COMNEXIA conducts a structured network assessment for Sandy Springs businesses that produces exactly those deliverables: a topology diagram, a firewall rule audit, and a written remediation priority list. No findings are held back to manufacture urgency. You get the full picture and decide how to proceed.
