Managed IT Services in Lewisville, TX
Lewisville mixes corporate offices on Lakepointe Drive, factories and distribution space along I-35E, and healthcare employers such as Medical City Lewisville. NetSys runs IT services for those businesses remotely from Brooklyn: the help desk, the network, security, Microsoft 365, backups and every vendor in between, under one month-to-month agreement.
The short answer
NetSys provides managed IT services to Lewisville, Texas businesses: an engineer-led help desk, around-the-clock monitoring and patching, ThreatDown managed detection and response, Microsoft 365 and Intune administration, restore-tested backups and vendor management, priced per user per month after an assessment. Service is remote and cloud-based from our Brooklyn office, and NetSys does not send engineers on site in Lewisville. Staff can reach the help desk from 3 a.m. to 10 p.m. Central any day of the week, and monitoring and emergency service run 24/7.

How managed IT is delivered in Lewisville
Lewisville offices are managed from Brooklyn through three things: the NinjaOne agent on each machine, the Microsoft 365 and Intune consoles, and the management portal of a Cisco Meraki or Fortinet firewall. Engineers patch overnight on Central time, answer alerts and fix most problems in a remote session the employee approves. When equipment fails, the replacement is configured before it ships. A laptop arrives registered with Autopilot, and a firewall arrives with its rules loaded from IT Glue. Someone on your staff, or the cabling contractor you already use, plugs it in with our engineer on the phone checking each port and link. NetSys does not send engineers on site in Lewisville, and the written agreement says so. Monitoring runs 24/7 from Brooklyn, and so does emergency service. Our staffed help-desk hours are 4 a.m. to 11 p.m. Eastern time (3 a.m. to 10 p.m. Central), seven days a week. The proposal states severe-incident escalation, authorized remediation and any other after-hours work.
Offices on Lakepointe Drive and along I-35E
Lewisville's office space clusters near the I-35E, President George Bush Turnpike and SH 121 interchanges, close enough to DFW Airport for companies with traveling staff. In February 2026, Avison Young reported that 1720 Lakepointe Drive at Corporate Pointe was fully leased after Prime Controls took 49,715 square feet and BayMark Health Services renewed 30,388. Public broadband maps show Frontier fiber reaching most Lewisville addresses, with Spectrum Business and Astound Business as other options to check at yours. We use that choice: two circuits from different carriers where the building allows, or a cellular link where it does not, automatic failover on the firewall, and alerts when either connection degrades so it gets repaired before both are down.
Manufacturers, distributors and the plant-floor network
Lewisville is also a place where things get made. Mary Kay opened its $100 million Richard R. Rogers Manufacturing and R&D Center here in November 2018, a 453,000-square-foot building for cosmetics, skin care and fragrance production. Smaller manufacturers and distributors along I-35E run the same kinds of systems at a smaller scale: an ERP with production scheduling, label and barcode printers, plant-floor PCs that cannot be rebooted mid-shift, and machine vendors who want remote access to their equipment. Managed IT for them means separating production equipment from office PCs and guest Wi-Fi on the firewall, giving each equipment vendor a time-limited, logged connection instead of an always-on remote tool, and patching plant-floor PCs in windows the shift supervisor has agreed.
Lake, dam and grid: planning for a closed office
Lewisville Lake runs along the north side of the city, and the U.S. Army Corps of Engineers has been working through an approximately $166 million safety modification program on Lewisville Dam, with the spillway work close to completion in July 2026. The Corps describes it as proactive work rather than a response to an immediate hazard. Floods are only one way an office closes. The February 2021 winter storm and its rolling outages put every Texas county under federal disaster declaration DR-4586, and the May 28, 2024 storms cut power to hundreds of thousands of customers across the Dallas area. Our continuity plan for a Lewisville business assumes the office is unusable for a week: email and files in Microsoft 365, business data backed up off site with a tested restore, and staff working from home on day one.
Medical and behavioral health offices in Lewisville
Lewisville's healthcare employers include Medical City Lewisville and BayMark Health Services, which renewed its Lakepointe Drive offices in 2026. Patient data raises the stakes for every practice near them. In July 2023, HCA Healthcare disclosed that contact and appointment details for about 11 million patients had been taken from an external storage location used for reminder messages, and Medical City Lewisville was among the North Texas hospitals listed. Information like that makes convincing phishing: a text quoting a real appointment, or an email naming a real physician. For medical and behavioral health offices, managed IT adds a documented HIPAA risk analysis, encrypted devices, quarterly access reviews, training records that meet the Texas requirement to train new employees within 90 days of hire, and backups of the data the practice controls.

What managed IT costs in Lewisville
Managed IT is priced per user per month for a fully managed agreement, and the number moves with four things more than with headcount: how many servers you run, whether you need after-hours coverage beyond monitoring, how much compliance documentation you carry, and whether we are co-managing alongside an internal person or running everything. We quote from an assessment, not a phone call, and the agreement runs month to month. What belongs in the monthly fee versus what is billed separately is set out on our managed IT pricing page.
Who this fits, and who it does not
Best fit: 10 to 75 employees, one or two offices plus remote staff, already on Microsoft 365 or ready to move there, and either no internal IT or one person who is underwater.

Managed IT Services in Lewisville: FAQs
How does managed IT work for Lewisville organizations?
It is delivered remotely and through the cloud. NinjaOne monitors every device and server, ThreatDown's security operations center and our engineers respond to threats, and Microsoft 365, Intune and the firewall are administered from Brooklyn. Staff contact the help desk by phone, email or Teams between 3 a.m. and 10 p.m. Central, seven days a week, and an emergency reaches a dedicated engineer at any hour. Nobody from NetSys works on site in Lewisville, so hardware ships ready to connect and your team or contractor does the physical part with an engineer guiding them.
What IT services do Lewisville businesses get from NetSys?
Under one month-to-month agreement: the help desk, monitoring and patching, endpoint detection and response, email security, Microsoft 365 and Intune, backup and disaster recovery, network and firewall management, and vendor management for carriers and software makers. Consulting projects such as a server retirement, a move to SharePoint or the infrastructure for an ERP upgrade are quoted separately. Manufacturers can add plant-floor network segmentation and controlled vendor access, and medical offices can add HIPAA risk analysis and documentation. Companies with their own IT staff can choose co-managed IT and keep the parts they want.
How much do managed IT services cost in Lewisville?
The fee is per user per month, set after an assessment, and NetSys does not publish a rate because two companies of the same size can need very different work. In Lewisville the biggest swings come from plant-floor and warehouse devices that need managing alongside office PCs, the number of servers still running in the building, compliance documentation for a medical practice, and how much cleanup the assessment uncovers. Projects, hardware and licenses are quoted separately, and the agreement carries no long-term contract or early-exit penalty.
Can you manage IT for a Lewisville manufacturer?
Yes. We manage the office side and the plant-floor network together but keep them apart: production PCs, controllers and label printers on their own segment, office users on another, guests isolated. Equipment vendors get logged, time-limited remote access approved by your staff. Patching follows a schedule your operations lead agrees, so a line is never interrupted mid-shift. If you supply the Department of Defense, DFARS 252.204-7012 and NIST SP 800-171 still apply even though CMMC Phase 2 certification was suspended in July 2026, and we keep those controls and their evidence current.
How do you keep a Lewisville office working if the internet goes down?
The firewall carries two connections where the building allows it, typically a Frontier or Spectrum circuit plus a second carrier or a cellular modem, and fails over automatically, so most staff notice a short pause at worst. We get the alert, open the ticket with the carrier and chase the repair. Because mail, files and Teams live in Microsoft 365, anyone can keep working from a phone hotspot or from home. During onboarding we also check which card terminals, phones and alarm panels depend on the office line, so the failover plan covers them too.
