IT Services and Cybersecurity in Bohemia, NY
Bohemia's working side runs along Veterans Memorial Highway and the industrial streets south of Long Island MacArthur Airport: electronics and machining shops, life-science suppliers, distributors and the offices that serve them. NetSys is the IT company that manages the whole environment for those firms, with engineers who drive out from Brooklyn when a problem needs hands.
The short answer
NetSys provides IT services in Bohemia, NY: managed IT, a help desk staffed by engineers, cybersecurity, backups and IT projects for manufacturers, life-science suppliers, distributors and professional offices around Long Island MacArthur Airport. Bohemia is about 46 miles from our Brooklyn office, inside our on-site coverage, so most problems get resolved over a remote connection, and an engineer travels out when a network, a machine or a move needs hands. Help desk lines open at 4 a.m. Eastern and stay staffed until 11 p.m., weekends included, while monitoring and emergency response continue around the clock. Each company's per-user monthly price comes from an assessment, and there is no long-term contract.

What an IT company handles for a Bohemia business
Most Bohemia companies that call us have IT that grew one problem at a time. A typical machine shop off Knickerbocker Avenue has an ERP server under a desk, shop-floor PCs nobody patches, a copier dealer who also set up the Wi-Fi and an owner who resets the passwords. A typical distributor on Johnson Avenue has warehouse scanners from one installer, phones from another and a firewall whose login left with the last consultant. NetSys takes over all of it in a single contract, covering NinjaOne monitoring and patch management, the help desk, Microsoft 365, endpoint and email security, backups, the network and the vendors who sell you all of it. Manufacturers should also read the Bohemia manufacturing page, which covers the shop floor, the ERP and NIST SP 800-171 work in more depth.
Where we provide on-site support around Bohemia
Bohemia sits about 46 miles from our Park Slope office, inside the 50-mile on-site radius. The drive runs about an hour and a quarter outside rush hour by the Long Island Expressway or the Southern State, and closer to two hours when traffic backs up, so visits are booked with a time window rather than promised in minutes. The same coverage reaches Ronkonkoma, Holbrook, Oakdale, Sayville, Bayport, Islandia, Central Islip and Hauppauge. Engineers come on site for closets and cabling, firewalls and switches, warehouse Wi-Fi, shop-floor workstations and office moves, after remote troubleshooting has ruled out a faster fix. Patchogue, Medford, Bellport and Port Jefferson are 50 to 60 miles out, and we confirm the drive with you before any visit there; the East End is served remotely.
Industries near the airport, and the systems they run
Bohemia's industrial streets hold more technical work than the low buildings suggest. Sartorius, the biopharma equipment maker, runs its North American headquarters here. North Atlantic Industries moved its embedded computing and power supply operation into a 90,000-square-foot Bohemia building in 2021, and Patheon's site on Veterans Memorial Highway designs and prints clinical trial labels for drug makers. Around them are contract machinists, electronics assemblers, distributors and building trades, plus accountants, insurance agencies and medical offices serving the people who work there. At Long Island MacArthur Airport, which the Town of Islip owns and runs, charter operators, flight schools and fixed-base operators keep their own networks. The systems we support are described generically: an ERP and shop-floor system, a quality management system, a warehouse management system, CAD files on a file server and Microsoft 365 for the rest.
Buildings, circuits and power on the airport side of Islip
Industrial buildings around the airport create predictable IT problems. The network closet ends up in a mezzanine or beside the compressor room, where heat and dust shorten the life of switches. Office PCs, machine controllers, test stations, cameras and guest devices often share one flat network, and long cable runs to the far end of the floor fail quietly. Internet choices vary by street, so we check Optimum, Verizon Fios and Lightpath at each address and add a second path where a down circuit stops shipping. Power is the other weak point. When Tropical Storm Isaias came through in August 2020, PSEG Long Island counted roughly 440,000 of its customers affected, and the August 2014 cloudburst that dropped 13.57 inches on the airport's weather station in a single day set a preliminary state rainfall record. Battery backup, clean shutdowns and off-site copies of every backup are part of the design.
What the Suffolk County attack taught local IT
The largest public cyberattack in the area hit the county government itself. According to the Suffolk County Legislature's investigative report, criminals using the Blackcat ransomware launched their attack on September 8, 2022, after gaining access to county systems months earlier. They stole data including network maps, passwords and residents' personal information, 911 operations were affected, the county website was unavailable for more than five months, and the county refused a ransom demand that began at $2.5 million. The report found that a pass-through in the perimeter firewalls for the County Clerk's office put the whole network at risk. The lessons fit a 25-person plant in Bohemia: no firewall exceptions that nobody reviews, prompt patching of internet-facing systems, multifactor sign-in everywhere, separated networks, and backups an intruder cannot delete.
New York law and contract rules, cited
New York's SHIELD Act, at General Business Law section 899-bb, expects every business holding New Yorkers' private information to protect it with safeguards that fit its size and the sensitivity of what it keeps. Since December 21, 2024, section 899-aa also requires notifying affected New York residents within 30 days after a breach is discovered. Manufacturers that handle controlled unclassified information under defense contracts work under DFARS 252.204-7012, which requires NIST SP 800-171 and reporting of cyber incidents within 72 hours. CMMC's third-party certification phase was suspended in July 2026, yet self-assessments at Levels 1 and 2 and a current SPRS score still apply. Insurance agencies and other businesses licensed by the Department of Financial Services also follow 23 NYCRR Part 500. This is general information, not legal advice.

Bohemia, NY FAQs
Who provides IT services in Bohemia, NY?
Several IT companies serve the Islip area, from solo technicians to large managed service providers. NetSys, an IT firm since 1998, works from one office in Park Slope, Brooklyn, and our engineers drive to Bohemia for on-site work. The work spans day-to-day management, help desk calls, security, backups, Microsoft 365 and one-off projects, all without a long-term contract, and 98% of our clients stay with us. When you compare IT companies, ask who answers the phone, whether engineers come to the building, and what leaving would involve.
Do you provide on-site IT support in Bohemia?
Yes. Bohemia is about 46 miles from Park Slope, where our only office is, so it sits inside our on-site coverage, and engineers travel out for work that needs hands: a failed switch, warehouse Wi-Fi, new workstations on the shop floor, cabling or a move. Most problems are still fixed remotely first because that is faster. The drive takes roughly 75 minutes outside rush hour, so visits are scheduled with a window, and anything severe, such as ransomware or a building with no internet, is routed directly to your dedicated engineer.
How is IT priced for a Bohemia company?
Per user per month, set after we assess your environment. The figure moves with headcount and devices, shared shop-floor machines, servers on site, how many security tools each device needs, and any compliance evidence such as NIST SP 800-171 documentation for defense work. We do not publish prices, because two 30-person companies on the same street can need very different amounts of work. Projects such as a server replacement, a network rebuild or a move are quoted after scoping, and agreements run month to month.
Can the shop floor and the office share one network safely?
They can share the building, not the network. We give office PCs, shop-floor machines, cameras, phones and guest Wi-Fi their own network segments, enforced by a Fortinet or Meraki firewall we manage, with rules that allow only the traffic each one needs, such as a machine controller reaching the folder that holds its programs. Machine vendors get named, time-limited remote access instead of a permanent tunnel. If ransomware lands on an office laptop, segmentation keeps it away from the equipment that makes your product.
We do defense work. Where does CMMC stand in late 2026?
CMMC Phase 2, which would have required third-party Level 2 certification before contract award from November 10, 2026, was suspended by the Department of War on July 13, 2026, and Phases 3 and 4 wait on a reform task force's review. Still required today: Level 1 or Level 2 self-assessments, an up-to-date SPRS score with its affirmation, the DFARS 252.204-7012 clause, and NIST SP 800-171 Revision 2. We keep building to 800-171 so your documentation holds up whatever the review decides.
What happens when the power or the circuit goes out?
The plan depends on what stops the business. For most Bohemia companies that is the ERP, shipping and label printing, and email. We put the server and network on battery backup with automatic clean shutdown, add a cellular or second wired circuit behind the firewall so it fails over on its own, and keep backups in Datto SIRIS or Veeam with a copy off site. If the building is dark for a day, staff can work from Microsoft 365 at home, and the ERP comes back first when power returns.
How do we switch from our current IT provider?
Onboarding takes about four weeks. We inventory users, devices, vendors and admin credentials, install monitoring and security tools, and prove the backups with a test restore before anything is cut over. The cutover itself happens after hours so production is not interrupted, and the old provider's access is removed the same day. Staff get a short briefing on contacting the help desk and are introduced to their dedicated engineer. An unhelpful outgoing provider slows things down but does not stop them, and the agreement is month to month from day one.
Is there a way to test your work before signing?
Yes. Our one free offer is an external penetration test: an engineer probes your internet-facing systems remotely, within limits we set together in writing, and reports what an attacker could reach. The report stays with you either way. Manufacturers often use the findings to answer a customer's supplier security questionnaire or a cyber insurance renewal, and the fixes it recommends can be done by us or by whoever runs your IT now.
One IT company for the office, the shop floor and everything between.
