Network Solutions in Marietta, Georgia

Managed Network Services in Marietta, GA, Built for Security-First Business Operations

COMNEXIA has designed, deployed, and managed business networks across Cobb County and the greater Atlanta metro since 1991. Our Roswell headquarters puts us minutes from Marietta's business corridor along Powers Ferry Road, Barrett Parkway, and the Cumberland district. When a network goes down or a misconfigured firewall opens a gap, we respond locally, not from a remote call center two states away.

Why Marietta Businesses Need a Security-First Network Strategy

A network is not just cables and a router. It is the enforcement layer for every security control your business runs. A flat, unsegmented network means a compromised workstation can reach your accounting server, your VoIP controller, and your cloud credentials simultaneously. COMNEXIA builds Marietta business networks around the principle that the network itself is a security tool, configured before a breach happens, not patched together afterward.

Marietta auto dealerships carry a specific regulatory obligation worth naming directly. The FTC Safeguards Rule, updated and enforced under 16 CFR Part 314, requires financial institutions including auto dealers to implement a written information security program that includes network access controls, encryption in transit, and continuous monitoring. A properly segmented network with logged traffic is not optional for a dealership running CDK Global, Reynolds and Reynolds, or Dealertrack. It is a compliance requirement with documented teeth.

What COMNEXIA Delivers: Named Platforms, Real Configuration

We do not recommend generic "enterprise-grade" hardware. We specify, configure, and manage the actual equipment your environment requires.

• Next-Generation Firewalls: We deploy Fortinet FortiGate and SonicWall NGFWs with application-layer inspection, geo-IP filtering, and intrusion prevention signatures active from day one. FortiGate's Security Fabric integration allows us to correlate firewall events with endpoint telemetry inside a single dashboard, which is directly useful for FTC Safeguards audit documentation.
• Business Wi-Fi: Ubiquiti UniFi and Cisco Meraki access points, deployed with separate SSIDs for staff, guest, and IoT devices. Each SSID maps to its own VLAN so that a visitor's laptop cannot reach your internal file shares or your DMS terminals on the showroom floor.
• VLAN Segmentation: We build discrete VLANs for workstations, servers, VoIP, point-of-sale, cameras, and guest traffic. Inter-VLAN routing is controlled at the firewall with explicit allow rules, not implicit trust. This limits lateral movement if any single device is compromised.
• VPN and Zero Trust Network Access: For remote staff and vendor access, we configure site-to-site IPsec VPNs and SSL VPN tunnels on FortiGate, or deploy ZTNA policies that authenticate identity before granting application-level access rather than full network access. Dealers granting CDK or Reynolds remote support sessions benefit directly from vendor-scoped ZTNA policies instead of broad VPN tunnels.
• Structured Cabling: Clean, labeled, documented Cat6A runs with proper patch panel terminations and cable management. Disorganized wiring causes real downtime during moves, adds, and changes. We document every run in network diagrams kept current in your onboarding documentation package.

How Network Management Connects to COMNEXIA's Broader MSP Stack

Network hardware does not manage itself. COMNEXIA monitors every managed device using NinjaOne RMM, which provides real-time alerting on interface errors, CPU spikes on firewall appliances, failed VPN tunnels, and rogue DHCP servers. Firmware and security patches for network devices are tracked inside the same patch management workflow we use for endpoints, so a critical FortiOS vulnerability is not sitting unpatched for 90 days because nobody owns the task.

Every new Marietta client goes through a documented onboarding process that produces a current-state network diagram, a VLAN map, firewall rule documentation, and Wi-Fi topology records. Those documents become the baseline for monthly reporting, which shows interface utilization, firewall block counts by category, and any configuration changes made during the billing period. You receive a record of what your network did, not just a bill.

A Specific Scenario: Marietta Dealership with a Multi-Rooftop Network

A Marietta dealership group operating two or three rooftops on a shared Dealertrack instance needs more than a router at each location. COMNEXIA builds that environment with FortiGate firewalls at each site connected by IPsec tunnels, a centralized UniFi controller managing Wi-Fi across all locations, and VLANs that isolate the DMS network from the guest Wi-Fi customers use on the showroom floor. NinjaOne monitors all sites from a single pane, and monthly reports give the dealer principal documented evidence of network controls for FTC Safeguards compliance review.

Get a Network Assessment for Your Marietta Business

If your current network has no VLAN segmentation, no next-generation firewall policy, or no documented configuration baseline, those are concrete gaps that create real liability, especially for businesses handling customer financial data under the FTC Safeguards Rule. COMNEXIA has served Cobb County businesses for over three decades and can assess your Marietta location and deliver a written findings report with specific remediation steps.
