Managed IT Services in Nassau County, New York
Nassau County sits inside the New York metropolitan area we already cover on-site, and its business mix — medical and dental practices, law firms, accounting practices, and family-owned operators around Garden City, Mineola and Hicksville — is close to the centre of what NetSys does. Managed IT, cybersecurity, and disaster recovery, on month-to-month terms.
The short answer
NetSys provides managed IT services and cybersecurity to businesses across Nassau County, New York — Garden City, Mineola, Hicksville, Great Neck, Hempstead and the surrounding communities. Nassau County falls inside the New York metropolitan area, one of our named on-site coverage regions, so engineers travel to Long Island for work that needs hands, including the free on-site penetration test. The service itself is the same everywhere: helpdesk and patching, 24/7 monitoring, endpoint detection and response, identity and email security, Microsoft 365 and cloud administration, and immutable backups with restores we test rather than assume. Our headquarters is at 1 Prospect Park SW in Brooklyn; we do not claim a Long Island office. Agreements run month to month.

- Headquarters: Brooklyn, NY — no Long Island office claimed
A county built on regulated practices
Nassau's commercial character is dominated by professional practices — medical, dental, legal, accounting — clustered around Garden City, Mineola and the hospital corridor. Those businesses carry regulated data on small headcounts, which is the exact profile that gets hurt worst by ransomware and phishing: enough valuable data to be a target, rarely enough internal IT to be a hard one. Our published medical case study, covering seven connected locations, is the closest analogue in our portfolio.
Multi-site is the normal shape here
Practices on Long Island grow by opening another location rather than by filling a bigger one, and the technology usually does not keep up: separate file stores, separate printers, patient or client records emailed between sites because nothing else connects them. Encrypted site-to-site networking so several offices behave as one managed environment is core to our practice, not a special project.
Who this fits in Nassau County
Medical and dental groups, law and accounting firms, and family-owned businesses that have outgrown a break-fix relationship. If you already have an internal IT person, co-managed IT adds 24/7 coverage and security depth behind them. If you are opening a second or third location, the connectivity and security architecture should be designed once rather than improvised three times.
A four-location dental group around Garden City and Mineola
A composite example of work we do, written so you can picture the first 90 days. It is not a specific client — our real, named engagements are in case studies.
Four offices, roughly 50 staff, and practice-management software holding patient records at each site with no reliable connection between them. Backups are a local appliance at each location that nobody has restored from. Front-desk staff share a login at two of the sites. The group's owner has read enough about ransomware in healthcare to be worried, and has been told by an insurer that the current arrangements will not renew as they are.
- The free on-site penetration test at the largest site, establishing the realistic path to patient data and producing a prioritized fix list
- Shared logins eliminated — individual accounts with multifactor authentication, so access to patient records is attributable to a person
- The four sites connected over encrypted site-to-site networking, mirroring the architecture in our published seven-location medical case study
- Managed endpoint detection and response across every workstation, with 24/7 monitoring behind it
- Immutable offline backups replacing the local appliances, with a restore actually performed at one site and timed
- Documentation of controls, access and recovery procedure sufficient to answer the insurer's renewal questions truthfully
Patient records live in one managed environment with attributable access, recovery is a tested procedure with a measured recovery time, and the insurance renewal is answerable from documentation. Engineers travel to the sites when hands are needed; everything else runs remotely.

Nassau County, NY FAQs
Do you serve Long Island and Nassau County?
Yes. Nassau County sits within the New York metropolitan area, which is one of our named on-site coverage regions, so engineers travel to Long Island for work needing hands — including the free on-site penetration test, network and server work, and the discovery session that opens a managed relationship. Our office is in Brooklyn and we do not claim a Long Island address; what we do claim is that Nassau is inside the area we already cover.
Do you have experience with medical and dental practices?
Yes, and it is published rather than asserted. Our medical case study covers a practice running seven locations connected in real time over an encrypted VPN mesh, and we maintain a dedicated medical compliance practice. Regulated-data environments — where access has to be attributable, backups have to be provably restorable, and downtime has direct patient impact — are a core part of the work rather than an adjacent one.
Can you connect several Nassau County offices together?
Yes, and on Long Island it is usually the first thing worth fixing. Encrypted site-to-site networking makes several locations behave as one managed environment with one set of permissions, which removes the habit of emailing records between offices because nothing else connects them. Our published medical case study runs seven locations on exactly that architecture.
What happens if we get hit by ransomware?
The honest answer is that the outcome is decided before the attack, by whether your backups are immutable and whether anyone has actually restored from them. Every NetSys client hit by ransomware has fully recovered — a 100% record — and that record rests on tested restores rather than luck. We put immutable offline backups in place, run and document a real restore, and write down the recovery-time objective so you know the answer before you need it.
Do you require a long-term contract?
No — every NetSys agreement is month to month, on Long Island as everywhere else. We keep clients by performing rather than by locking them in; retention runs 98%.
What does managed IT in Nassau County include?
A full IT department without the headcount: a helpdesk your staff can call, 24/7 monitoring and patching across every server and workstation, the security stack behind it — multifactor authentication, managed endpoint detection and response, email filtering, DNS protection, immutable backups — plus Microsoft 365 and cloud administration, vendor management with your ISP and software providers, and on-site engineer dispatch when something needs hands. You get a dedicated account manager rather than a ticket queue.
