IT Services & Cybersecurity in Joliet, IL
Joliet is the Will County seat, a city of about 150,000 with two hospital campuses nearby, the county courts, two casinos and the nation's largest inland port on its southern edge. NetSys is an IT company that runs managed IT, help desk support, cybersecurity and IT consulting for Joliet organizations remotely from Brooklyn, on month-to-month agreements.
The short answer
NetSys is an IT company for Joliet organizations that want one provider for the whole job: managed IT, a help desk staffed by engineers, cybersecurity built on ThreatDown managed detection and response, Microsoft 365 administration, backups and consulting for projects such as a new warehouse network. All of it is delivered remotely and through the cloud. NetSys does not send engineers on site in Joliet; laptops arrive enrolled in Windows Autopilot, and your staff or cabling contractor connects other equipment while an engineer confirms it. The help desk is staffed 3 a.m. to 10 p.m. Central daily, monitoring and emergency service run 24/7, and managed IT is priced per user per month after an assessment.
- One office, in Brooklyn, NY; Joliet is about 740 miles away and is served remotely, with no engineers sent on site
- Laptops ship enrolled in Intune and Windows Autopilot; your staff or cabling contractor connects network equipment while an engineer confirms it remotely
- 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
What one IT provider covers for a Joliet organization
Think of NetSys as the IT department a growing Joliet organization would hire if it could find and keep the people. Day to day, that means engineers who answer staff questions, keep every computer patched, watch for attacks through ThreatDown, run Microsoft 365 and Intune, filter email through Barracuda and back up servers and cloud data with Datto or Veeam. It also means owning the network: the Meraki or Fortinet firewall, the switches and Wi-Fi in each building, and the carrier circuit behind them. When something breaks at a vendor, whether a carrier, a copier company or a software provider, we make the call and stay with it until it is fixed. The documentation lives in IT Glue and belongs to you, not to us. A dedicated account manager, reachable on a real cell number, reviews hardware age, renewals and upcoming projects with you every quarter.
How support reaches a Joliet office without a local technician
Everything is remote. Engineers in Brooklyn connect through the NinjaOne agent on each computer, your Microsoft 365 tenant and the firewall's cloud dashboard, so a password reset, a security alert or a firewall rule change in Joliet is handled exactly as one in Manhattan would be. NetSys does not send engineers to Joliet, and we say so before you sign. Physical tasks are planned instead: laptops are registered in Windows Autopilot at the supplier and ship to the office or the employee's home, firewalls and access points arrive preconfigured, and your office manager or a cabling contractor makes the connections with an engineer on the phone. Joliet is on Central time, so our staffed hours there are 3 a.m. to 10 p.m., every day, and alerts that arrive overnight still reach an engineer who can act on them.
Joliet industries and the systems they depend on
Will County's development agency lists Saint Joseph Medical Center, which Prime Healthcare took over from Ascension on March 1, 2025, as Joliet's largest employer, with 2,532 staff, and Silver Cross Hospital in New Lenox at the same size; medical and dental offices cluster around both, running EHR, imaging and billing systems under HIPAA. As the county seat, Joliet holds the Will County Courthouse and county government, about 2,370 employees, plus the law, title and accounting firms that serve them. Joliet Junior College, founded in 1901 and widely described as the country's first public community college, and the University of St. Francis add education. Industry runs from the ExxonMobil Joliet Refinery and food producers such as Great Kitchens to logistics operators like Cadence Premier Logistics, while Harrah's and Hollywood Casino bring hospitality. Each needs IT shaped around its own software and rules.
Storms, floods and planning for a dark office
Will County's federal disaster declarations read like a list of what to plan for. The F5 tornado of August 28, 1990 killed 29 people as it tracked through Plainfield, Crest Hill and Joliet. In 2013 the county was declared twice, for flooding in April and for the tornado outbreak of November 17. Storms from July 13 to 16, 2024 then brought tornadoes, straight-line winds and flooding, and the September 2024 declaration covering Will, Cook and five other counties opened federal aid to residents. For a Joliet office, the planning is practical: battery backup sized to shut servers and network gear down cleanly, a second internet path over 5G or LTE, files kept in SharePoint and OneDrive so work continues from home, and backup copies stored outside the region so one storm cannot reach both the office and its backups.
Cyber incidents close to Joliet
Recent attacks have reached Joliet institutions directly. In May 2024, Joliet Public Schools District 86 suffered a cyberattack that exposed names, Social Security numbers and birth dates; it later notified 1,495 people, and the LockBit ransomware group claimed responsibility. That same month, the Ascension health system, then the owner of Saint Joseph Medical Center, disclosed a ransomware attack that disrupted care across its network, although it described the impact at the Joliet hospital as minimal. In June 2024, CDK Global, a software provider to auto dealers based in Hoffman Estates, was attacked, and dealerships across North America went back to paper. Over the past three years NetSys has handled more than 30 ransomware incidents and recovered every one; clients that already had a disaster recovery plan were working again within 24 hours.
Illinois law that applies to Joliet businesses
Three Illinois rules shape most Joliet IT programs. The Personal Information Protection Act (815 ILCS 530) requires reasonable security for residents' personal information, prompt notice to affected people after a breach, and notice to the Attorney General when more than 500 Illinois residents are involved, no later than the residents hear. The Biometric Information Privacy Act (740 ILCS 14) matters to every employer with fingerprint or face timeclocks: a published retention schedule, destruction when the purpose ends or within three years of the person's last interaction, and written consent first; an amendment signed August 2, 2024 counts repeat scans of one person by one method as a single violation. Lawyers near the courthouse have Illinois Rule of Professional Conduct 1.6(e), which requires reasonable efforts to protect client information, and medical offices have HIPAA. This is general information, not legal advice.

Joliet, IL FAQs
Who provides IT services in Joliet?
Several firms do, from local shops to national providers. NetSys is a Brooklyn-based managed IT and cybersecurity company, in business since 1998, that supports Joliet organizations remotely rather than from a Will County office. What you get is engineers, with degrees in electrical and electronics engineering and computer science and Cisco and Microsoft certifications, behind one month-to-month agreement for support, security, Microsoft 365, backups, networking and vendor management, plus an account manager on a real cell number. If you want a technician who can walk your building every week, choose a provider based nearby; we will tell you so on the first call.
How does IT support work for Joliet organizations?
Staff reach the help desk by phone, email or Teams from 3 a.m. to 10 p.m. Central, any day of the week, and an engineer connects to the computer to fix the problem. Security monitoring and emergency response never stop, so a ransomware alert at night is worked at night. NetSys does not send anyone on site in Joliet: new laptops ship ready to use, firewalls and access points arrive configured, and your staff or contractor connects them while we watch from the console. Ransomware, a system outage, lost internet or failed email goes straight to your dedicated engineer.
How much do IT services cost for a Joliet business?
Managed IT and IT support are priced per user per month after we assess the environment, and projects are quoted after scoping. We do not publish rates because the drivers vary: how many people and devices you have, whether a server still runs in the building, how many sites and circuits we manage, whether shared warehouse or front-desk computers need their own setup, and what documentation your industry requires. Hardware and licenses are billed separately at quoted prices. Agreements run month to month with no penalty for leaving, and 98% of clients stay.
How does remote onboarding work for businesses in Joliet, IL?
It usually takes two to four weeks and nobody has to travel. We begin with a call and a small agent installed on each computer, which produces the inventory. You approve a written plan before anything changes. Staff then receive a short note about the help desk and a scheduled prompt to set up multifactor sign-in. The old antivirus comes off as ThreatDown goes on, passwords move into Keeper, and backups are proved with a real restore. If hardware needs replacing, it arrives configured, and the only thing staff do is sign in.
What services do you offer to businesses in Joliet, IL?
Everything an internal IT department would do. Day to day, that is the help desk, device and patch management, Microsoft 365 and Intune administration, and backups. For security, we run ThreatDown MDR, filter mail through Barracuda, train staff with KnowBe4 and scan for weaknesses with Rapid7. We also manage firewalls and Wi-Fi, keep the vendor list, and handle projects: a new warehouse network, a move from a file server to SharePoint, a Windows 11 refresh or retiring a Windows Server 2016 machine before support ends in January 2027. The Joliet managed IT and IT support pages go into detail.
Is there a free way to test our security first?
Yes, one. We run a free external penetration test: a remote check of what your organization exposes to the internet, such as the firewall, VPN, email sign-in and websites, within a scope we agree in writing beforehand. You get a report of what an outside attacker could see and the order we would fix things in. Everything beyond that, including a look inside your network or Microsoft 365 tenant, belongs to the paid assessment that sets managed IT pricing. To arrange the test, book a call with an engineer.
Can you support a company with sites in Joliet and Chicago?
Yes, and the distance between sites changes nothing for remote support. A company with an office downtown, a warehouse in Elwood and staff in the Loop gets one standard everywhere: the same firewall policy, Wi-Fi design, device settings and sign-in experience, so people moving between buildings work the same way in each. The help desk, documentation and account manager cover every location under one per-user agreement. We check carrier options separately at each address, because Joliet and Chicago buildings are served by different mixes of cable, fiber and fixed wireless.
