Managed IT Services in Dallas, Texas

Mid-sized Dallas companies sell to some of the largest corporations in the country, and those customers send security questionnaires, audit requests and uptime expectations. NetSys runs the whole IT environment behind them: devices, Microsoft 365, security, backups, networks and every vendor, remotely from Brooklyn, with a named account manager and month-to-month terms.

All IT services in Dallas, TX

The short answer

NetSys provides managed IT services to Dallas businesses, covering the help desk, continuous monitoring, patch management, ThreatDown detection and response, identity and device administration in Microsoft 365 and Intune, restore-tested backups, Meraki or Fortinet firewalls and the vendors behind your systems, plus a roadmap reviewed every quarter. You pay per user per month, at a rate set after an assessment. All of it is remote and cloud-based; NetSys engineers are not sent on site in Dallas. The help desk is staffed from 3:00 a.m. until 10:00 p.m. Central (4:00 a.m. until 11:00 p.m. Eastern) every day, and monitoring and emergency service never stop.

How managed IT is delivered in Dallas

Our engineers in Brooklyn manage your environment through the same tools you would want an internal team to use. NinjaOne watches every computer and server, ThreatDown watches for attacks, Microsoft 365 and Intune hold identities and device policies, and the firewall is managed from its cloud console. IT Glue documents all of it, from network diagrams to vendor contacts, so knowledge does not walk out the door with one person. On-site visits are not part of a Dallas agreement. Hardware arrives preconfigured from the supplier; your office manager or a local low-voltage contractor connects it, and we finish the setup remotely. You get one monthly report and one quarterly review covering the whole environment. 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.

Selling to corporate Dallas: questionnaires and controls

Few metros have as many corporate headquarters within one commute. Bisnow counts 10 of North Texas's 24 Fortune 500 headquarters in Irving and Las Colinas alone, and Plano's Legacy West and Uptown add more. The mid-sized firms that supply them, from staffing and marketing agencies to engineering and logistics companies, regularly receive vendor security questionnaires asking about MFA, encryption, backups, incident response and access reviews. Managed IT makes those answers true and provable. Conditional Access reports show MFA coverage, Intune shows every laptop encrypted, backup test results and patch reports are on file, and a written incident response plan exists before anyone asks. When a questionnaire arrives, we help fill it in from evidence rather than optimism.

Vendor management: one call instead of six

A typical Dallas office deals with an internet carrier, a phone system, a copier lease, Microsoft licensing, a line-of-business software vendor and a building manager, each with its own support line. Under managed IT, those calls are ours. We open the ticket with AT&T or Spectrum when a circuit drops, with the software maker when the accounting package or EHR throws errors, and with Microsoft when a service is degraded, and we stay on it until it is resolved. Frontier customers should note that Verizon completed its purchase of Frontier in January 2026, so account and support channels may change, and we track that for you. Renewal dates, license counts and contract terms sit in IT Glue, and your account manager flags them before anything renews automatically.

Towers, office parks and the circuits behind them

Buildings set the limits of an IT design in Dallas. Towers in Uptown and Las Colinas usually offer a choice of carriers in the riser, while many office parks in Plano and Frisco are served by a single AT&T or Spectrum circuit, and one backhoe can take a whole suite offline. Managed IT plans around the building you have. Where there is a second carrier, we order diverse circuits; where there is not, the firewall fails over to a cellular connection. UPS units keep the network up through short outages and shut servers down cleanly in long ones, which matters in a state where the February 2021 grid emergency left offices dark for days. And because email, files and Teams run in Microsoft 365, people can keep working from home whenever the office cannot open.

The first 30 days for a Dallas company

Days one to ten are discovery. An engineer collects admin credentials from you or your outgoing provider, installs NinjaOne on every machine, and documents accounts, licenses, the firewall, backups and vendors in IT Glue; inactive accounts and unused licenses usually surface here. Days ten to fifteen produce a written plan with costs, which you approve before anything changes. The last two weeks are the cutover, scheduled around your month-end close or busy season: ThreatDown replaces the old security software, MFA and Conditional Access are enforced, backups move and a restore is proven, and staff get one help desk number. The outgoing provider's tools and access are removed, and the first quarterly review goes on the calendar.

Published case study

Law office: Microsoft 365 with layered security and cloud-to-cloud backup

A 25-attorney firm in the greater New York metro was losing unbillable hours to an outdated file server and an email server that needed weekly attention. NetSys mapped the firm's matters and document workflows first, moved email to Exchange Online and documents to SharePoint and OneDrive in a matter-based structure over a weekend cut-over, layered anti-phishing protection, DNS filtering, multifactor authentication and endpoint protection across attorney devices, and set independent cloud-to-cloud backup of the whole tenant. The firm reported 82% fewer IT support incidents per month within two quarters and about 3.5 hours per attorney per week recovered from IT friction.

What managed IT costs in Dallas

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.

How the monthly fee is built

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 Dallas: FAQs

Can a Brooklyn IT company really manage our Dallas office?

Yes. NetSys has run IT for businesses since 1998 from one office in Park Slope, Brooklyn, and manages Dallas environments remotely. We do not have a Dallas office or local staff, and we do not pretend to. What you get is engineers educated in computer science and in electrical and electronics engineering, Cisco and Microsoft certifications, a dedicated account manager with a real cell number, and a dedicated engineer for severe problems.

How does managed IT work for Dallas organizations?

We take responsibility for the whole environment and run it remotely. Devices are monitored and patched continuously, security alerts are handled by ThreatDown's security operations center and our engineers, backups are checked daily, and vendors are managed on your behalf. Staff reach the help desk from 3:00 a.m. until 10:00 p.m. Central, seven days a week, and emergencies are handled at any hour. There is no on-site component in Dallas; equipment ships configured, and local contractors handle the physical work.

What does managed IT in Dallas include, and what does it cost?

The fee covers the help desk, monitoring and patching, ThreatDown MDR, Microsoft 365 and Intune administration, backups with restore tests, firewall management, vendor management and quarterly reviews. Each user is billed monthly, at a figure set by an assessment. Servers, multiple locations, compliance reporting for clients or regulators, and how much an internal IT person keeps all weigh on it more than the number of staff. Hardware, licenses and projects get separate quotes, and our managed IT pricing page explains what drives the number.

Can you work with our existing IT person?

Yes, as co-managed IT. Many mid-sized firms have one capable IT manager stretched across help desk tickets, projects and vendor calls. We take the parts they choose, often the help desk, after-hours monitoring, patching and security, and give them our tools, documentation and engineers to escalate to. Responsibilities, systems and coverage hours are written down before work begins, so nothing falls between the two teams, and the split can change as your needs do.

Do we have to sign a long contract?

No. Agreements are month to month, and nobody signs a multi-year term, because we would rather keep clients by doing the work well, and 98% of them stay. Onboarding projects and hardware are quoted separately. Everything we document about your environment in IT Glue, from network diagrams to vendor contacts and configurations, describes systems you own, so if you ever change providers the information goes with you.
