Crestline Technologies designs, deploys, and manages secure, scalable network infrastructure for businesses across East Tennessee — from structured cabling and managed Wi-Fi to next-gen firewalls, VPNs, and 24/7 network monitoring built to grow with your business.
Most small business networks were built reactively — a router here, an access point there, a firewall added after something went wrong. The result is patchwork infrastructure that slows your team down and creates security gaps your existing vendor isn't watching.
Crestline Technologies designs networks from the ground up — or re-engineers existing ones — using enterprise-grade hardware and a structured methodology that balances performance, security, and long-term scalability.
From structured cabling and managed Wi-Fi to next-gen firewalls, VLANs, and SD-WAN — we build and manage the entire network stack as part of your CrestOne managed IT plan. One team, zero gaps between your network and your security.
Start With a Network Assessment →A breakdown of each network service Crestline Technologies delivers — what it includes, why it matters, and what your team can expect from engagement start to ongoing management.
Professional installation of copper and fiber-optic cabling — organized, tested, and tested against TIA-568 standards. A clean physical layer is the foundation everything else depends on. We build it right the first time.
Enterprise-grade wireless providing seamless coverage, high device capacity, and properly segmented access for employees, guests, and IoT devices. No dead zones. No over-saturated channels. No consumer gear.
Multi-layered perimeter security built around a properly configured next-generation firewall — not the basic stateful inspection in your ISP router. Fully integrated with your cybersecurity posture.
Properly configured VPN infrastructure so your team works securely from anywhere — without exposing your internal network through poorly implemented consumer-grade remote access solutions.
The backbone of your internal network. Properly configured managed switches enable high-speed communication, traffic prioritization, and segmentation that flat, unmanaged networks simply cannot provide.
Continuous visibility into your network health — bandwidth utilization, device availability, latency trends, and anomalous traffic. Problems are caught and escalated before your team feels the impact.
For businesses with multiple locations, SD-WAN delivers intelligent traffic routing across internet connections — providing reliability and centralized visibility without the cost of MPLS circuits.
Your network doesn't end at your router. We extend your infrastructure securely into Azure, Microsoft 365, and hybrid cloud environments — optimizing traffic paths for cloud-first workloads.

The gateway of your network. Routers connect your business to the internet and direct traffic between different networks. Business-grade routers provide policy-based routing, dynamic routing protocols, and NAT that consumer models simply can't match at scale.
The backbone of your internal network. Managed switches connect computers, printers, servers, and VoIP phones — enabling high-speed communication, VLAN segmentation, and QoS traffic prioritization that unmanaged switches cannot provide.
Your network's first line of defense. A next-generation firewall inspects all inbound and outbound traffic using deep packet inspection, enforces application policies, blocks threats, and logs everything — far beyond the basic NAT firewall in your ISP router.
The heart of your wireless network. Commercial-grade access points transmit Wi-Fi signals across your office with high concurrent device capacity and proper VLAN-based segmentation — delivering the reliability and security that consumer mesh systems can't touch.

This helps us calculate your baseline bandwidth and infrastructure requirements
Video calls are bandwidth-intensive — especially with multiple concurrent meetings across your team
Large files like videos, CAD drawings, or database backups require significantly more bandwidth to move

Based on your answers, here's how your current setup compares to what your business actually needs:
A 30-minute consultation with our network team is enough to review your current setup and outline exactly what needs to change — and what doesn't.
Schedule a Network ConsultationWhether deploying a new network from scratch or re-engineering an existing one, our process follows a consistent four-phase structure that keeps your business running throughout.
A thorough audit of your existing network — device inventory, topology mapping, bandwidth analysis, Wi-Fi heatmapping, and security review. You receive a written findings report before any work begins. No surprises, no hidden scope.
Discovery findings become a formal network design — hardware specifications, VLAN architecture, AP placement, firewall ruleset, and a deployment plan. Fully priced and scoped before you commit to implementation.
Implementation is scheduled to minimize business disruption — often after hours or in staged phases. All components are tested and documented before cutover. Your team gets a full walkthrough of what changed and why.
After deployment, 24/7 network monitoring via our NOC keeps your infrastructure performing at spec. Quarterly reviews, firmware updates, and capacity planning are included in CrestOne Advanced and Ultimate plans.
We're not a remote NOC that fires alerts into a ticket queue. We're your Knoxville IT team — with enterprise-grade tools and the local presence to be there when something needs hands-on attention.
Local network engineers who know East Tennessee buildings, ISPs, and business environments — and can be on-site when remote resolution isn't enough. No ticketing to a distant NOC.
We work with Cisco, Fortinet, Ubiquiti, Aruba, Meraki, and other leading vendors. We recommend what's right for your environment and budget — not what earns us the most margin.
Your network is your security perimeter. With Crestline Technologies managing both, there's no gap between your network team and your security vendor — and no finger-pointing when something goes wrong.
24/7 monitoring means we catch bandwidth saturation, device failures, and anomalous traffic before your team notices. Most issues are resolved before a ticket is ever opened.
