IT Services & Cybersecurity in Houston, TX
Houston companies run on energy, medicine, trade and engineering, and every one of them works through hurricane season. NetSys is an IT company that supports Houston organizations remotely from Brooklyn: engineers on the help desk, managed security, Microsoft 365 and cloud administration, and backups built to come back after a storm, all under one month-to-month agreement.
The short answer
NetSys is an IT company that runs IT services and cybersecurity for Houston, TX organizations from its Brooklyn office, entirely through remote and cloud tools. A single agreement puts our engineers on your help desk and covers Windows and Mac management in Intune, the Microsoft 365 tenant, ThreatDown detection and response on every endpoint, Barracuda mail filtering, Datto or Veeam backups that we restore-test, and the calls to your other vendors. Houston sits about 1,400 miles from Brooklyn, and NetSys does not send engineers on site there. Engineers answer from 3 a.m. to 10 p.m. Central every day, and monitoring and emergency service never stop. Pricing is a monthly fee per user, set once we have assessed your environment.
- One office, in Brooklyn, NY; Houston is about 1,400 miles away and is served remotely
- Remote and cloud-based support only; computers arrive pre-enrolled through Windows Autopilot, and your staff or a local cabling contractor plug in network gear
- Monitoring and emergency service run 24/7; the help desk is staffed seven days a week from 4 a.m. to 11 p.m. Eastern time (3 a.m. to 10 p.m. Central)
- Month-to-month agreements and 98% client retention
IT services NetSys delivers in Houston
A Houston company of 10 to 150 people tends to collect its IT one problem at a time: a server in a closet off the Katy Freeway, Microsoft 365 licenses bought by three different office managers, a firewall still running the password its installer chose, and separate vendors for phones, copiers and the core business application. NetSys takes responsibility for all of it. Our engineers answer the help desk, Intune enrolls and polices every Windows and Mac computer, we administer the Microsoft 365 tenant and Entra ID sign-ins, ThreatDown managed detection and response watches each endpoint, and Barracuda filters mail. Datto SIRIS or Veeam backs up servers and cloud data, and restores are proven on a schedule rather than assumed. NinjaOne patches machines in windows you approve, IT Glue holds the documentation, and Cisco Meraki or Fortinet firewalls are managed from Brooklyn. When the ERP, the EHR or the document system misbehaves, we open the vendor ticket and stay with it. Larger projects, such as retiring a server or merging two tenants after an acquisition, are quoted separately after scoping.
How remote onboarding works for a Houston business
Because Houston is served remotely, onboarding is designed to finish without anyone from NetSys in your building. The first week is discovery over video calls and inventory scripts: every device, account, license, circuit and vendor goes on a list, and the previous IT provider turns over passwords and admin accounts in writing. In week two, NinjaOne and ThreatDown agents install after hours and multifactor sign-in rolls out one team at a time, scheduled around shift changes, month-end close or clinic hours. Week three moves backups to Datto or Veeam and proves a restore. Week four closes stale accounts and delivers a written findings report with fixes in priority order. Every new laptop is registered in Windows Autopilot before it leaves us, so a hire in Katy opens the box, signs in and finds their apps waiting. Firewalls and access points arrive configured; someone on your team or a local low-voltage contractor connects them, and our engineer finishes the setup remotely. The proposal states plainly that NetSys does not send engineers on site in Houston.
Houston industries and the systems they run
The Greater Houston Partnership's 2025 Houston Facts counts 26 Fortune 500 headquarters in the region, the third most of any U.S. metro, and the smaller firms around them follow that base. Architecture and engineering services employ about 75,900 people, the largest professional subsector, much of it tied to energy, petrochemical and infrastructure work. Health care employs more than 435,000, anchored by the Texas Medical Center. Port Houston ranked first among U.S. seaports for international tonnage in 2024, which keeps freight forwarders, customs brokers and distributors busy from Pasadena to Baytown. Add 694 chemical plants, roughly 4,100 legal-services establishments and a deep bench of CPA firms. Each runs a different core application: an EHR and billing system, project accounting beside CAD and modeling tools, a document management system, an ERP with shop-floor modules, a transportation or warehouse management system, or tax and practice-management software. We manage the identity, devices, network and backups those applications depend on and deal with each vendor directly.
Hurricanes, freezes and the power grid
Recent federal disaster declarations covering Harris County read like a design brief. Hurricane Harvey flooded the region in August 2017 (DR-4332). Winter Storm Uri froze the grid in February 2021 (DR-4586). The spring 2024 storms, including the May 16 derecho that blew out windows in downtown towers, were declared DR-4781. Hurricane Beryl followed in July 2024 (DR-4798), and CenterPoint Energy reported 2.26 million customers without power, with more than 88,000 still waiting a week later. A Houston office has to plan on losing its building, its power or its circuit for a week or more. So we move servers into Azure or a colocation facility instead of a ground-floor closet, keep immutable backup copies outside the Gulf Coast, add a cellular backup link to the firewall and size battery runtime for a clean shutdown, not for riding out the outage. Staff laptops reach files, email and business systems from anywhere with power and a signal, and the incident plan carries a call list that works when email is down.
Circuits, buildings and cyber incidents close to home
Downtown and Uptown towers usually have carrier choice; a tilt-up warehouse near the Ship Channel or a strip-center clinic on Westheimer may have a single circuit. AT&T Business, Comcast Business and Houston-based LOGIX Fiber Networks are options to check at your address, and we set the firewall to fail over between two of them, with both circuits documented and watched. The local incident record explains the rest of the design. Ransomware hit the Houston Housing Authority in September 2024, and the agency later told the Texas Attorney General that more than 30,000 people were affected. OakBend Medical Center in Richmond took systems offline to rebuild after a Daixin Team attack that began September 1, 2022. In August 2021, attackers used a zero-day flaw in a password self-service appliance to breach a Port Houston web server, and port staff isolated it before operations were touched. Patched internet-facing appliances, multifactor sign-in on every account, managed detection and offline backups close each of those paths.
Texas law and industry rules that apply in Houston
Under section 521.052 of the Texas Business and Commerce Code, a business must maintain reasonable procedures to protect sensitive personal information and must shred, erase or otherwise destroy records it will not keep. Section 521.053 sets the breach clock: affected individuals within 60 days of determining that a breach occurred, and the Attorney General within 30 days, through the office's online form, when at least 250 Texans are involved; the office warns that a filed report may become an open record. Since July 1, 2024, the Texas Data Privacy and Security Act has required reasonable data security practices, but it exempts businesses the SBA defines as small (apart from a consent rule for selling sensitive data), HIPAA covered entities and Gramm-Leach-Bliley financial institutions. Medical offices answer to HIPAA and Health and Safety Code chapter 181, and since January 1, 2026 Texas has required covered entities to store electronic health records in the United States. Tax preparers add the FTC Safeguards Rule, investment advisers SEC Regulation S-P, and defense suppliers NIST SP 800-171. This is general information, not legal advice.

Houston, TX FAQs
Who provides IT services and cybersecurity for Houston companies?
Houston has plenty of local IT firms, and NetSys is a remote option for organizations that want engineers on the help desk and security run as one service. We have provided IT and security since 1998 from a single office in Brooklyn. The engineers have degrees in electrical engineering, electronics engineering or computer science, with Cisco and Microsoft certifications. A Houston agreement covers the help desk, device management, Microsoft 365, managed detection and response, email filtering, backups and vendor management on a month-to-month basis. We have no Houston office or Houston staff, and we say so up front.
How does IT support work for Houston organizations?
Your staff reach engineers by phone, email or ticket, and the engineer connects to the computer remotely, fixes the problem and records what changed in IT Glue. The help desk is staffed from 3 a.m. to 10 p.m. Central every day, and monitoring and emergency service cover the other hours. Critical issues get a phone response within ten minutes and a remote response within thirty; standard issues get thirty minutes and one hour. Ransomware, a dead circuit or an email outage goes straight to your dedicated engineer. NetSys does not travel to Houston, so hardware ships ready to use and your team or a cabling contractor handles anything physical.
What does IT support cost for a Houston business?
Managed IT and IT support are billed per user per month. We set the rate after an assessment rather than from a price sheet, and four things move it most: the servers and on-premises applications you still run, the number of sites and circuits, any compliance work in scope such as a HIPAA risk analysis or an FTC Safeguards program, and how much an internal IT person keeps. Projects such as moving a file server to Azure are priced separately once scoped. The agreement is month to month, never a multi-year contract.
What happens to our systems when a hurricane is headed for Houston?
Before the season starts, we agree a written storm checklist with you. When a storm is forecast, we confirm the latest backups restore, check that working files are syncing to SharePoint or your document system, and test the firewall's cellular link. As landfall approaches, on-premises servers are shut down cleanly from Brooklyn so a surge cannot corrupt them, and staff take laptops home. Afterward we bring systems back in the order your recovery plan sets, restore from Datto or Veeam if hardware was lost, and ship replacement equipment that rebuilds itself through Autopilot.
Can NetSys work alongside our internal IT staff?
Yes. Plenty of Houston companies with 50 to 200 people keep an IT manager who knows the plant, the clinic or the trading floor better than any outsider. In a co-managed arrangement we take the parts that are hard for one person to cover: after-hours monitoring, managed detection and response, patching through NinjaOne, backups and overflow help desk tickets. Your IT manager keeps administrative rights, sees every ticket and decides what we change. The split is written down before work begins, so nobody assumes the other side handled a security alert.
Do you support offices in Katy, Sugar Land, Pearland and the rest of the metro?
Yes, on the same terms as an office downtown. Support across Greater Houston is remote, so it makes no difference to us whether your staff sit in Katy, Pearland, Clear Lake, Cypress or in several of those places at once. Multi-office companies get one standard build: the same Meraki or Fortinet firewall template, the same Wi-Fi settings and the same Intune policies at every location, so a fix made at one office reaches all of them. The Woodlands, in Montgomery County, has its own location page with details for businesses there.
What is the free external penetration test?
It is the only free offer NetSys makes. Within a scope agreed in writing, our engineers test your internet-facing systems from outside: the firewall, VPN and remote-access portals, email security settings and any public web applications you name. The test is performed remotely and does not touch internal systems. You receive a written report of what an attacker could see and reach, ranked by severity, with the fixes. The 2021 Port Houston intrusion began at an exposed password self-service server, which is exactly the kind of system this outside view finds.
Can you help us answer cyber insurance questionnaires?
Yes. Cyber insurance applications typically ask about multifactor authentication, endpoint detection, backups and how they are protected, email filtering, privileged accounts and staff training. We answer the technical questions with evidence instead of checkmarks: Conditional Access policies, ThreatDown coverage reports, backup test logs and KnowBe4 completion records. Where an honest answer would be no, we tell you well before the renewal date and fix the gap, because a wrong answer on an application can become a reason to deny a claim after an incident.
