IT services we deliver in Union County
NetSys covers the whole of a company's IT or the parts it wants to hand off. Managed IT bundles the help desk, 24/7 monitoring, patching, Microsoft 365 and Intune administration, ThreatDown managed detection and response, Barracuda email protection and Datto or Veeam backups with dated restore tests. IT support suits firms that need a help desk and device management. Cybersecurity can be bought on its own, from a multifactor rollout and email security to vulnerability scanning and the free external penetration test. Network work covers Fortinet and Cisco Meraki firewalls, switching, Wi-Fi and second circuits. Projects, from a Microsoft 365 migration to the IT side of an office move, are quoted after scoping. Vendor management comes with every ongoing plan, so the carrier, the copier company and your software vendor have one NetSys contact.
Where we provide on-site support in Union County
All 21 municipalities are inside our on-site area. From our office in Park Slope the drive is roughly 30 minutes to Elizabeth and Linden off-peak; Cranford, Roselle and Rahway take 35 to 45 minutes; Union, Springfield, Westfield and Summit about 50; and New Providence, Berkeley Heights, Scotch Plains and Plainfield nearly an hour, longer at rush hour. Engineers come out for firewall and switch replacements, cabling, Wi-Fi surveys, hardware swaps, new-hire desks and office moves. The help desk, monitoring and patching run remotely every day, and most tickets end there. Warehouses near the port can book early-morning visits before the first trucks, and multi-tenant campuses such as The Park in Berkeley Heights are scheduled around building management's access rules.
Port, airport and warehouse operators in Elizabeth, Linden and Hillside
Union County sits at the center of the region's freight network. The Port Newark-Elizabeth Marine Terminal, the Port Authority's main container complex, straddles the Newark and Elizabeth line; Newark Liberty's Terminal A, opened in 2023, lies wholly within the county; and the county's economic development office counts more than 50 independent freight and trucking companies based here, along with participation in Foreign Trade Zones 49 and 235. Elizabeth also has New Jersey's largest Urban Enterprise Zone, with nearly 1,000 businesses. For forwarders, customs brokers and warehouses, IT means scanners and label printers that work at the start of the first shift, customs and carrier portals with individual logins, a warehouse management system with a tested backup, and a cellular failover so a cut circuit does not stop loading.
Pharmaceutical headquarters and the firms that serve them
Union County has become a headquarters address for drug and consumer health companies. Merck completed the move of its global headquarters to its Rahway campus in 2023, Kenvue opened its global headquarters at 1 Kenvue Way in Summit in March 2025, and Haleon is relocating its North American headquarters to The Park, the former Connell Corporate Park in Berkeley Heights. Nokia Bell Labs remains in Murray Hill until its planned move to New Brunswick. Around those campuses works a long tail of smaller suppliers: contract research and manufacturing firms, packaging and printing companies, staffing and marketing agencies, and consultants. They are judged by vendor security reviews, so we run multifactor authentication, endpoint detection and response, encryption and tested backups for them, and keep the evidence ready to send.
Westfield, Cranford and Summit: professional practices and contractors
Downtown Westfield, Cranford's North Avenue and Summit's Springfield Avenue hold law and accounting practices, wealth managers, medical and therapy offices and design firms, mostly small teams in older buildings. Construction is the county's largest business group by number of companies, about 1,100 by the county's count, and professional and technical services follow at about 1,000. Overlook Medical Center in Summit, Trinitas Regional Medical Center in Elizabeth and RWJ University Hospital Rahway anchor the medical offices around them. What these firms usually need first is a real firewall instead of the carrier's router, multifactor sign-in, managed laptops, email protection against payment fraud and backups that restore. Lawyers near the Union County Courthouse in Elizabeth add RPC 1.6(f) confidentiality duties, and practices handling patient records add the HIPAA Security Rule.
Local security and compliance notes
Two kinds of incident shape planning here. The first is ransomware: in May 2024 the Township of Union school district had to pull critical systems offline after an attack the LockBit group later claimed. The second is water. Ida's remnants in September 2021 killed four residents of a flooded Elizabeth apartment complex, and in July 2025 a flash flood that the governor put at six inches of rain in under two and a half hours killed two people in Plainfield. The legal frame is N.J.S.A. 56:8-163, which puts a report to the Division of State Police ahead of any customer notice after a breach, and, for larger data controllers including nonprofits, the New Jersey Data Privacy Act, effective January 15, 2025. Your counsel decides what applies; we keep the logs, backups and records the response depends on. This is general information, not legal advice.

Union County, NJ FAQs
Who provides IT services in Union County, NJ?
NetSys is one IT company that serves Union County: a managed IT and cybersecurity firm founded in 1998, with its only office in Park Slope, Brooklyn. Engineers come on site across the county, and the help desk, monitoring and security run from Brooklyn every day. One per-user monthly agreement covers support, security, Microsoft 365, the network and backups, and it runs month to month, with no long-term contract.
Do you provide on-site IT support in Union County, NJ?
Yes. Union County is inside our on-site area, so engineers come to offices, warehouses and clinics for hardware swaps, cabling, firewall and switch work, Wi-Fi problems and moves. Most issues are fixed remotely first through the help desk, which is faster for your staff. Elizabeth is about 30 minutes from Park Slope off-peak, and we give you an arrival time whenever a visit is booked.
Where in Union County do you provide on-site support?
Everywhere in the county: Elizabeth, Linden, Rahway, Hillside, Roselle, Roselle Park, Union, Kenilworth, Cranford, Garwood, Clark, Winfield, Westfield, Fanwood, Scotch Plains, Plainfield, Springfield, Mountainside, New Providence, Summit and Berkeley Heights. That includes the port and airport side of Elizabeth, the Route 1 and Route 22 corridors, the downtowns in Westfield, Cranford and Summit, and campuses such as The Park in Berkeley Heights. Drive times run from about half an hour to about an hour.
What services do you offer to businesses in Union County, NJ?
Managed IT, IT support and help desk, cybersecurity with managed detection and response, firewall and network management, backup and disaster recovery, Microsoft 365 administration and migrations, co-managed IT for companies with their own IT staff, IT consulting and projects, cyber-insurance readiness and AI automation. Each has its own page on this site. Most companies start with managed IT, which bundles the help desk, security and backups into one per-user fee, and add projects as needed.
How is IT priced for a Union County business?
Ongoing support is billed per user per month, and the rate comes from an assessment of your environment; NetSys does not publish a price. The number of users and devices, shared warehouse computers and scanners, servers, sites, and compliance work such as HIPAA or a pharmaceutical client's vendor review all move the fee. Projects, hardware and licensing are quoted separately after scoping. Agreements are month to month, so the service has to earn its place each month.
How do we start, and is anything free?
Start by booking a call with an engineer, who will ask about your sites, users, systems and what is going wrong. The one free offer is our external penetration test: a remote test, within a scope we agree in writing, of what your firm exposes to the internet, with a report you keep either way. A proposal for ongoing support follows a short review of your environment, priced per user per month.
Can you keep a freight or warehouse business running through a flood or outage?
That is the design goal. We keep warehouse and customs data in the cloud or behind immutable off-site backups, put network gear on battery backup and off the floor, and add a cellular failover to the firewall so loading can continue when a circuit is cut. A written recovery plan lists what comes back first and who decides. NetSys clients with a disaster recovery plan in place have been back within 24 hours of a ransomware incident.
Which New Jersey laws apply to Union County businesses?
Every business that holds New Jersey residents' personal information is covered by the breach statute, N.J.S.A. 56:8-163. Larger data controllers, nonprofits included, also fall under the New Jersey Data Privacy Act. Industry rules sit on top: the HIPAA Security Rule for medical practices, SEC Regulation S-P for advisers, the FTC Safeguards Rule for tax preparers and NIST SP 800-171 for defense suppliers. Your counsel decides what applies; we supply the controls and the records.
