Enterprise WiFi & Heatmapping
Enterprise-grade wireless with firewalls, remote access, and dedicated guest networks. Includes RF heatmapping to find and fix dead zones before they become complaints.
Network Segmentation & Security
Clean separation of work, guest, and IoT traffic — firewalls, VLANs, and access policy designed so a guest device is never one hop from your business systems.
Managed Gateway & VPN
Application VPN and hardware gateway services, including Tailscale and similar overlay networks, for secure remote access across sites and remote staff.
IP Surveillance & Access Control
IP-based video surveillance, access control systems, and remote monitoring — designed on the same segmented network as everything else, not bolted on after the fact.

Smart home and smart building ecosystems covering climate and energy management, plus IP-based audio/visual systems, tied together and remotely manageable.
VoIP, SIP Trunking & AI Auto-Attendant
VoIP service with AI auto-attendants, SIP trunking for physical desk phones, and softphone integration with Teams, Zoom, and Webex. AI-assisted attendants handle customer calls and texts around the clock.
How It Works
Design once. Install right. Manage it after.
01
Site Assessment
We walk the space, map coverage needs, and identify where security, wireless, and cabling actually need to go — not guesswork.
02
Design & Build
A single design that covers networking, security, and smart systems together, so nothing gets retrofitted or fights with itself later.
03
Install & Verify
Professional install with heatmap and coverage verification before we call it done — not after you notice the dead zone.
04
Manage & Monitor
Ongoing remote monitoring and managed support, so problems get caught before they become downtime.
About
One integrator, instead of five vendors who don't talk to each other.
Most businesses end up with a WiFi vendor, a camera vendor, a phone vendor, and an automation vendor — none of whom coordinate, and all of whom blame each other when something breaks. 321 Networks runs it as one system: network, security, voice, and building automation designed and supported together.
