A Nassau County IT company, based in Wantagh, run by a US-based team.
MJN Technology Services is headquartered in Wantagh, in the middle of Nassau County. We support businesses in Garden City, Mineola, Plainview, Bellmore, Farmingdale and across the county, and we have been working in Long Island IT since 1999.
That matters less for drive time than people expect, because the work is done remotely by an in-house team, and it matters a great deal for everything else. We know the professional firms here, the compliance regimes they answer to, and the specific ways a Nassau County business gets targeted.
Nassau skews heavily toward professional services: law firms, CPA practices, wealth advisors, insurance agencies, title companies and medical and dental offices, most of them under fifty people. Those businesses hold sensitive client data, answer to a regulator, and rarely have anyone in-house whose actual job is technology. That combination is what we are built for.
Most providers in this market self-assess their own security. We submitted to an accredited third-party assessor against 177 controls under the GTIA Cybersecurity Trustmark program, and GTIA's review board confirmed the result.
You get the same people, based in the United States, who learn your systems and remember your setup. Not a rotating queue of technicians reading a ticket for the first time.
Day-to-day support is covered by one flat monthly rate. Hourly billing punishes you for having problems and teaches your staff to stop reporting them, which is how small issues become expensive ones.
The five things every Nassau County client gets, whether you are five people in Mineola or fifty in Garden City.
Unlimited, flat rate, answered by people who know your setup.
Your staff can call as often as they need without anyone counting. That is deliberate. The moment support becomes something people hesitate to use, they start working around problems instead of reporting them, and the workaround is almost always less secure than the fix.
Underneath the help desk sits 24/7 monitoring of your servers, workstations and network devices, plus patching on a daily schedule. Most of what would have become a support call gets resolved before anyone in your office notices there was anything to call about.
Built for firms that answer to a regulator.
A great deal of Nassau County's economy runs on regulated professional services, and the rules are not optional. Insurance agencies and brokers answer to NY DFS Part 500. Wealth advisors and RIAs answer to the SEC and FINRA, including Reg S-P. CPA and accounting firms need an IRS WISP. Law firms carry attorney-client privilege into every system they touch.
The security stack is the same either way: Zero-Trust architecture, 24/7 managed detection and response, multifactor authentication, automated endpoint remediation and security awareness training for your staff. What changes for regulated firms is the documentation, because being secure and being able to prove you were secure are two different problems, and only one of them shows up during an audit or a cyber insurance renewal.
Verified every day, with proof.
Almost every business that has lost data had backups running. What they lacked was evidence those backups would restore. We use screenshot verification, which boots each protected system from its backup and captures a dated image of it running, so the proof exists before you need it rather than after.
Copies are held offsite where an attacker on your network cannot reach or overwrite them, and your Microsoft 365 or Google Workspace data is backed up separately from the platform itself. Nassau is coastal, which makes the ordinary disasters worth planning for too, not only the deliberate ones.
Configured deliberately, not left on defaults.
Most Microsoft 365 tenants we inherit were set up once to get email working and never revisited. Administrators without multifactor authentication, sharing links that never expire, audit logging switched off, and no backup separate from Microsoft's own retention. None of that is a product flaw. It is a set of decisions nobody made.
We migrate businesses off aging on-premise servers when that is genuinely the right move, harden identity and access, and set up Teams, SharePoint and OneDrive with enough structure that finding the current version of a document is never a conversation. Where a line-of-business application truly needs local file access, we say so rather than forcing it into the cloud.
Your staff are already using it. The question is whether you can see it.
In most offices somebody is already pasting client information into a free AI tool to summarize or reformat it. They are not being reckless, they are trying to work faster. But for a Nassau County firm holding privileged or regulated client data, where that information ends up is a real problem rather than a theoretical one.
Banning it does not work, it just moves the activity to personal phones where you have no visibility. We set up business accounts your company controls and administers, write a short readable policy about what may go into them, train your team on where these tools are confidently wrong, and automate the repetitive work that is genuinely safe to automate.
What business owners here ask before they change IT providers.
All of Nassau County. Our clients include businesses in Garden City, Mineola, Plainview, Bellmore, Farmingdale and Wantagh, where we are based. We also cover Suffolk County. Because the work is delivered remotely by our US-based team, where you sit in the county does not change your response time or your rate.
The overwhelming majority of IT work is faster remotely, and that is how we deliver it. Being local matters for the things that genuinely need hands on hardware and for knowing the market you operate in, not for resetting a password. One practical benefit of that model: there is no travel surcharge quietly built into your monthly rate.
Almost certainly not. Most of our Nassau County clients are professional services firms under fifty people, and that size is where the gap is widest: enough sensitive data and regulatory exposure to be a real target, not enough scale to justify hiring someone whose full-time job is technology. If you are genuinely too small to benefit, we would rather tell you that on the first call.
Because someone independent checked. MJN completed the GTIA Cybersecurity Trustmark assessment in May 2025, examined against 177 security controls by an accredited third-party assessor and confirmed by GTIA's review board. Most providers in this market self-assess and describe themselves as compliant, which is a different claim entirely. Ask any provider you are considering who verified their security and when.
Yes. That arrangement is called co-managed IT. Your internal person keeps user support and the institutional knowledge of how your business actually runs, and we take the infrastructure and security layer underneath: 24/7 monitoring, patching at scale, security operations and compliance documentation. Nobody gets replaced.
