IT Services & Cybersecurity in Detroit, MI
Metro Detroit is a region of 4.4 million people whose economy still runs through Ford in Dearborn, GM downtown and Stellantis in Auburn Hills, with banks, hospital systems, law firms and a deep bench of suppliers around them. NetSys is the IT company behind the help desk, security, Microsoft 365 and projects for organizations across Wayne, Oakland and Macomb counties, working remotely from Brooklyn.
The short answer
NetSys is an IT company that takes full responsibility for technology at Detroit-area businesses, nonprofits and practices: day-to-day support from an engineer-staffed help desk, managed IT, ThreatDown-backed cybersecurity, Microsoft 365, backups and project work such as migrations. We work remotely from our only office, in Brooklyn, and do not send engineers on site in Michigan; new laptops reach your people already enrolled through Windows Autopilot. Because Detroit keeps Eastern time, the 4 a.m. to 11 p.m. help desk schedule needs no conversion, and 24/7 monitoring covers the night. Pricing is per user per month, set after an assessment, and the agreement can end any month.
- One office, in Brooklyn, NY; Detroit is about 480 miles away and is supported remotely, with no engineers sent on site
- New computers are enrolled through Windows Autopilot before they ship, and firewalls and switches arrive configured for your staff to plug in
- 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, the same clock Detroit keeps
- Month-to-month agreements and 98% client retention
What one IT provider covers for a Detroit organization
A Detroit-area company of a few dozen or a few hundred people often has no full IT department, yet it carries every responsibility one would. NetSys takes that work under a single agreement. Engineers answer staff calls and fix problems while the caller waits, NinjaOne keeps every computer patched and reporting, ThreatDown analysts keep watch over every endpoint day and night, and our engineers administer Microsoft 365, Intune and Entra ID. Email passes through Barracuda filtering, servers and cloud data are backed up with Datto or Veeam, and restores are tested on a schedule. We also run the Meraki or Fortinet firewall, the switches and the Wi-Fi, and we manage the circuit from whichever carrier serves your address, such as Comcast Business, AT&T Business, 123NET or WideOpenWest. When the trouble belongs to another company, like your ERP reseller, phone vendor or copier lessor, we take it up with them directly. Every password, diagram and procedure is recorded in IT Glue, and those records are yours.
How support works without technicians in Michigan
NetSys keeps no staff in Michigan and does not send engineers to Detroit offices. The service runs over connections set up during onboarding: the NinjaOne agent on each device, direct administration of your Microsoft 365 tenant, and the firewall's cloud console. Through them an engineer in Brooklyn can clear a locked account in Livonia, roll back a bad update in Pontiac or isolate an infected laptop in Romulus without leaving the desk. Physical work is prepared before it ships. The supplier registers each new computer in Windows Autopilot and ships it wherever the user works, office or home, network equipment arrives configured, and a person you choose plugs it in while our engineer confirms the result. Critical problems get a phone response within ten minutes, and ransomware, outages, lost internet or failed email go straight to your dedicated engineer.
Detroit industries and the systems they run
The Detroit Regional Chamber counts nine 2025 Fortune 500 companies in the region: GM and Ford, Penske Automotive in Bloomfield Hills, Lear in Southfield, Ally Financial and DTE Energy in Detroit, BorgWarner and Autoliv in Auburn Hills, and Masco in Livonia. The organizations an IT provider actually serves sit around them. Suppliers and tool shops run an ERP with EDI links to their OEM customers. Engineering firms in Troy and Auburn Hills keep CAD workstations and license servers busy. Law firms near the federal courthouse on Lafayette Boulevard work from a document management system, mortgage and auto-finance companies downtown from loan platforms, and medical practices tied to Henry Ford Health, Corewell Health, the Detroit Medical Center, Trinity Health or Ascension from an EHR and billing system. Professional and business services employed about 374,000 people in the metro in September 2026, more than manufacturing's 235,100, so office IT matters here as much as plant IT.
Bridges, floods and storms: what Detroit plans around
Detroit's geography shapes its IT risks. The Gordie Howe International Bridge opened on July 27, 2026, giving the Detroit and Windsor crossing a second major span beside the Ambassador Bridge, which matters to any business with staff, warehouses or customers on both sides of the river. The weather is the other constant. Flooding on June 25 and 26, 2021 brought a federal disaster declaration for Wayne and Washtenaw counties, the February 2023 ice storm knocked out power to more than 600,000 DTE customers, and on September 3, 2026 an EF2 tornado crossed the east side from the Hancock Road area to Belle Isle, the first confirmed in the city since 1997. Our standard design assumes the power and the circuit will fail at some point: battery backup for servers and network gear, cellular failover on the firewall, files in SharePoint and OneDrive, and backups held outside southeast Michigan.
Recent cyberattacks around Detroit and what they teach
The past four years have given metro Detroit a run of public incidents. In 2022 four Michigan Medicine employees approved multifactor prompts after typing their passwords into a fake page, exposing records on about 33,850 patients. In November 2023 ransomware at Yanfeng in Novi rippled into Stellantis assembly plants. In 2024, McLaren Health Care and Karmanos Cancer Institute ran on downtime procedures after intruders spent weeks inside, and 743,131 people were later notified, while Wayne County's websites, property tax payments and inmate processing were disrupted by an attack that began on October 2. Each lesson maps to a control we deploy: number matching and Conditional Access for sign-in, ThreatDown managed detection on every endpoint, segmented networks, immutable backups and a written incident plan. Across more than 30 ransomware cases in the last three years, every NetSys client got fully back on its feet.
Michigan law for Detroit businesses
Michigan's breach statute is the Identity Theft Protection Act. Under MCL 445.72, a business that owns or licenses Michigan residents' personal information must notify them without unreasonable delay after a breach, unless it reasonably concludes that substantial loss, injury or identity theft is unlikely, and once notices go to more than 1,000 residents, the national consumer reporting agencies must hear as well. Knowingly skipping notice can cost up to $250 per failure, with a $750,000 cap per breach. Insurers and agencies follow the Insurance Data Security Act, MCL 500.550 to 500.565, including notice to the director of the Department of Insurance and Financial Services within 10 business days of determining that a qualifying cybersecurity event occurred. Senate Bill 360, which would add security-program duties and notice to the Attorney General, passed the Senate in August 2025 and went to a House committee. Medical practices add HIPAA, and defense suppliers add DFARS. This is general information, not legal advice.

Detroit, MI FAQs
Who provides IT services in Detroit?
Detroit has local IT shops, national managed service providers with Michigan branches, and firms like NetSys that work remotely. NetSys was founded in 1998, has one office in Brooklyn and supports Detroit-area organizations without a local branch. What you get is one agreement, renewable month by month, that covers support, security, Microsoft 365, backups, networks and your vendors; engineers whose degrees are in computer science or electrical and electronics engineering and who hold Cisco and Microsoft certifications; and an account manager reachable on a real cell phone. If your building needs a technician on the premises every week, choose a Detroit-based firm instead, and we will tell you that in the first conversation.
How does IT support work for Detroit organizations?
Anyone on your team can phone, email or Teams-message an engineer between 4 a.m. and 11 p.m. Eastern, any day of the week, and that engineer usually resolves the issue in the same conversation over a remote session. Monitoring and emergency response take the overnight hours. No one from NetSys comes to Detroit-area offices: new equipment is configured before it ships, and when a cable needs reseating or a device needs swapping, someone on your team does it while our engineer talks them through it. Four kinds of emergency, namely ransomware, a server or application down, a dead internet connection and stopped email, skip the line entirely, and your dedicated engineer takes them.
How much do IT services cost for a Detroit business?
Managed IT and IT support are each priced per person per month, and the number comes from assessing your environment first; projects get separate quotes once they are defined. We do not publish rates because the cost drivers vary so widely between Detroit businesses: headcount and devices, servers still running in a back room, the number of buildings and circuits, shared computers on a production floor or reception desk, and the security evidence your customers, insurer or regulator want to see. Licenses and hardware are priced separately. With month-to-month terms, there is no multi-year commitment hidden in the number.
How does remote onboarding work for businesses in Detroit, MI?
There are four steps, and none of them needs anyone to travel. First, a video kickoff where we learn who works where, which software matters most and what your current provider controls. Second, an agent rollout: NinjaOne and ThreatDown go onto every computer, and the inventory they report becomes a written plan you sign off on. Third, the security changes, in order: multifactor sign-in department by department, Keeper vaults, Barracuda filtering and a test restore of real files. Fourth, the handover of administrator credentials, domains and licenses from the outgoing provider. Laptops due for replacement ship enrolled in Autopilot, and most offices finish inside a month.
What services do you offer to businesses in Detroit, MI?
Five groups of work, all delivered remotely. Support: an engineer-staffed help desk, device setup and retirement, patching, and Microsoft 365 and Intune administration. Protection: ThreatDown managed detection and response, Microsoft Defender, Barracuda for email, KnowBe4 phishing exercises, Rapid7 vulnerability scans and Keeper for passwords. Recovery: Datto or Veeam backups with scheduled test restores and a written recovery order. Networks: the firewall, switches, Wi-Fi and the relationship with your carrier. Projects and advice: SharePoint and Azure migrations, Windows Server 2016 replacement before January 12, 2027, readiness for supplier questionnaires and NIST SP 800-171, and acquisition due diligence. Each Detroit service page covers its part in detail.
Can you support a company with offices in Detroit, the suburbs and Windsor?
Yes. We build every location from the same templates, so a laptop that works in Southfield works in a Romulus warehouse or a Windsor office without changes, and an employee moving between them signs in the same way. Firewalls at each site connect over encrypted tunnels, and Conditional Access treats Canada as an expected country for your Windsor staff rather than a warning sign. Windsor keeps Eastern time like Detroit, so the help desk hours do not shift. What we confirm address by address is the carrier, because Comcast Business, AT&T Business, 123NET and WideOpenWest serve different buildings, and which privacy law applies to the people each office holds records on.
Can we test our security before choosing a provider?
Yes. The only free service NetSys offers is an external penetration test, run remotely within a written scope you approve. Engineers look at your business the way an outside attacker would: open ports on the firewall, the VPN or remote desktop gateway, the Microsoft 365 sign-in page, exposed admin panels and your public websites. The report ranks each weakness by severity and says what we would close first. It gives you a concrete view of your exposure and of how our engineers write things up, with no obligation to continue. Internal testing and a review of your Microsoft 365 tenant go deeper and form part of the paid assessment used to price an agreement.
What should a Detroit company ask an IT firm before signing?
Start with who picks up the phone: an engineer who can fix the problem, or someone who only opens a ticket. Then get the commitments on paper: response times by severity, contract term and exit terms, and confirmation that your documentation and admin passwords come with you if you leave. Ask for the firm's ransomware record; ours is more than 30 incidents in three years with every client fully recovered. Detroit adds its own questions. Can the firm help answer an OEM security questionnaire or prepare for TISAX? Does it know MCL 445.72 and Michigan's insurance data security rules? And does it say clearly that its support is remote?
Plan your Detroit IT with an engineer, not a salesperson.
Tell us how many people and buildings you have, which counties or which side of the river they sit in, and which applications the business depends on. An engineer will walk you through how remote support would run for you and what the first month involves.
