Managed IT Services
There comes a point where IT stops being one person's side job. There's a second location, a server that still matters, a Microsoft 365 tenant nobody really owns, and a client or insurer asking security questions in writing. The NetSys Group runs that whole environment — 24/7 monitoring with fast helpdesk response, security, infrastructure, backups, and the strategy work — for established businesses on-site across New York City, Long Island, Westchester, the Hudson Valley, North Jersey and Fairfield County, CT, and remotely nationwide. Month to month, like everything we do.
Windows 11 24H2 Home and Pro stop receiving security updates on October 13, 2026. What to do before the deadline
The short answer
Managed IT services are ongoing IT support and management for a monthly fee: an outside provider runs your help desk, 24/7 monitoring, patching, security, backups and Microsoft 365. NetSys has provided managed IT since 1998, with a named account manager, on-site engineers in our published regions and month-to-month agreements that list what is included and what is billed separately.
Firms reach us with the same shape of problem: a Microsoft 365 tenant nobody owns, global admin handed out years ago and never taken back, one server still running an application the business cannot lose, and an insurer or a client asking in writing whether MFA is enforced. The NetSys Group has been taking that over from one Brooklyn office since 1998. We pick up the tenant, the identities in Entra ID, the devices in Intune, the network, the servers and the backups under a single agreement, write down who holds which admin credential, and put a named account manager in front of all of it. Engineers work on site across New York City, Long Island, Westchester, the Hudson Valley, North Jersey and Fairfield County, CT, and the rest is delivered remotely.
What We Watch, What We Patch, and Who Picks Up
Monitoring runs 24/7 and watches the things that take a business offline: disk and service health on servers, backup jobs that report success but have never been test restored, Entra ID sign ins from places nobody on payroll works from, Defender for Endpoint detections, and firewalls or VPN appliances still sitting on a firmware build with a public exploit, which is how SonicWall VPN firmware exploitation kept working. Patching follows Microsoft's monthly release for Windows, Microsoft 365 Apps and the Defender stack, with browsers, PDF readers and appliance firmware held to the same schedule and anything under active exploitation moved up rather than parked until the next window. When an alert needs a person, it goes to engineers who already know your environment, and your named account manager has a real cell number you already have. All of that sits in one month to month agreement that also carries the help desk, cybersecurity, PAM and PIM, disaster recovery planning and AI adoption work, so nobody has to argue about scope before a problem gets fixed.
Our Managed IT Services
24/7 Monitoring & Support
Monitoring runs around the clock, so a failed backup job, a domain controller filling its system drive, a Defender for Business detection or an Entra ID sign in from an impossible location is worked when it fires rather than found the next morning. Ordinary day to day tickets go through the help desk that is part of the agreement, staffed seven days a week from 4 a.m. to 11 p.m. Eastern time, and emergency service is available 24/7. When a call beats a ticket, your account manager's cell number is already in your phone.
- Real-time system and network monitoring
- Fast helpdesk response for everyday issues
- Remote and on-site support options
- Automated alerts for unusual activity
- Root-cause analysis and long-term issue prevention
IT Infrastructure Management
Our IT infrastructure management runs servers, switches, firewalls, laptops and the Microsoft 365 tenant as one environment instead of five separate vendor relationships: Intune for enrollment and device configuration, Entra ID for identity and conditional access, Defender for Endpoint on the machines, and a hardware list with real end of support dates so an aging server becomes a budget conversation before it becomes an outage.

Built for the Stage Where IT Becomes Infrastructure
The problems change shape as a company grows. This service is built for the stretch where technology stops being someone's side job and starts being infrastructure the business depends on.
- Two or more locations to connect, secure, and keep in sync
- A hybrid reality — cloud for most things, but a server or two still running something critical
- A first internal IT hire who needs an engineering bench behind them, not a replacement
- Clients, insurers, or regulators now asking security questions in writing
- Enough headcount that onboarding and offboarding happen most months
- Growth plans that make "we'll deal with it when it breaks" the expensive option

Client names are withheld. Each card is the scope of a real NetSys engagement, as delivered.
“Before working with NetSys, our technology and cybersecurity systems were spread across different vendors, and nobody had full responsibility for the environment. NetSys reviewed our Microsoft 365 accounts, network security, endpoint protection and backup systems, then created a prioritized plan around the risks most likely to interrupt operations. They improved account security, documented our recovery process and gave leadership a clear picture of what was protected and what still needed attention.”
Response times we actually commit to
“Fast response” is a slogan until it has numbers. These are the commitments NetSys clients get in writing:
| Severity | Phone response | Remote response | On-site response |
|---|---|---|---|
| Critical — you're down, or actively at risk | 10 minutes | 30 minutes | As fast as 1 hour, per agreement |
| Standard — something's broken, work continues | 30 minutes | 1 hour | Up to 6 hours, per agreement |
On-site times depend on where you are and the on-site tier written into your agreement — we put the numbers in writing instead of implying them. And there is no ticket queue in front of any of this: you call, a NetSys engineer answers. The help desk is staffed seven days a week from 4 a.m. to 11 p.m. Eastern time, and emergency service is available 24/7.
How onboarding runs, stage by stage
Taking over an environment follows the same order every time. Stages overlap, and none has a fixed length:
| Stage | What happens | What you have at the end |
|---|---|---|
| Discovery | We list users, devices, servers, licenses, vendors and admin credentials, and check backups and security settings as they stand | A written inventory, with the risks found ranked |
| Agreement | Covered users and devices, on-site arrangements, escalation contacts, after-hours work and exclusions are settled | A month-to-month agreement stating what is in and out |
| Handover | Admin rights move to named accounts, coordinated with your current provider, with overlap where it helps | A record of who holds each admin credential |
| Tooling | NinjaOne, endpoint protection and backup monitoring are installed on every covered device | Every device reporting into 24/7 monitoring |
| First fixes | MFA gaps, stale accounts and untested backups come first; bigger items are quoted as projects | A restore test on record and a priced project list |
| First review | Your account manager walks leadership through what changed and what comes next | A roadmap and budget to plan against |
Timing depends on how many devices and sites there are and how quickly the outgoing provider hands over, so we agree target dates in the proposal rather than publishing them.

Managed IT Services FAQs
Do you require long-term contracts?
No — every NetSys agreement is month to month. We keep clients by performing, not by locking them in; that's why our retention rate runs 98%.
Do we get a dedicated contact, or a ticket queue?
A dedicated account manager with their real cell phone number, backed by engineers who already know your environment. There is no tier-1 ticket queue to climb.
Can you co-manage IT with our internal team?
Yes. Many clients have us handle monitoring, security, and infrastructure while their internal staff keeps day-to-day user support — we fit the model to you.
Is NetSys managed IT a fit for a business like ours?
It is worth discussing when employees depend on shared systems, a Microsoft 365 tenant needs consistent administration, or support and security have become too much for one person. We first review users, locations, critical applications and the work your team wants to retain. If you already have an IT lead, a co-managed scope may be more appropriate than transferring every responsibility.
Do you cover NYC, Westchester, and Fairfield County, Connecticut?
Yes. We have one office, at 1 Prospect Park SW in Brooklyn, and we don't claim satellites we don't have. Engineers work on-site across New York City, Long Island, Westchester, the Hudson Valley, North Jersey and Fairfield County, CT, including Stamford and the Fairfield County coast. Everywhere else is remote-first, with on-site visits arranged in advance and scoped in the proposal. Monitoring runs around the clock remotely, and helpdesk and security work are delivered remotely regardless of where you sit.
What's covered by the managed service, and what's a separate project?
Monitoring, helpdesk, patching, endpoint and email security, backup administration, vendor coordination, user onboarding and offboarding, and the strategy and budget work are part of the managed service. Discrete projects — a cloud migration, an office build-out, a server replacement — get scoped on their own so you can plan them properly. We tell you which bucket something falls into before the work starts, not after.
We have more than one location. Can you support all of them?
Yes, and it's a large part of what we do. Our published medical case study connects seven locations in real time over an encrypted VPN mesh, with role-based access control and encryption in transit and at rest across all of them. Multi-site connectivity, a consolidated Microsoft 365 tenant, and one view of every site's health are normal work here, not a special engagement.
What's involved in switching from our current IT provider?
Start with the existing agreement, renewal date and an inventory of credentials, licenses, domains, systems and backups. We plan the handover with your authorized contacts, identify any period of overlapping support and verify recovery before retiring old tooling. Timing and notice obligations are agreed for your environment; the switching providers page explains the decisions in detail.
How are managed IT services priced?
Most often per user per month, with one fee covering each person's devices, support and security tools. The number moves with headcount, servers, sites, compliance obligations and how much on-site work you need, while hardware, licenses and projects are billed separately. NetSys publishes no rate card; the managed IT pricing page shows how a quote is built.
What is a managed service provider (MSP)?
A managed service provider (MSP) is an outside firm that takes ongoing responsibility for a business's IT for a monthly fee: help desk, 24/7 monitoring, patching, security, backups and planning. It replaces break-fix, where you pay by the hour after something fails. NetSys has been an MSP since 1998, and our glossary entry on managed service providers explains more.
What is the difference between IT services and managed services?
IT services covers any technology work, often bought by the hour when something breaks. Managed services means a provider takes ongoing responsibility for agreed systems for a monthly fee, watching and maintaining them before problems reach your staff. NetSys works on the managed model and scopes one-off projects, such as a migration, separately.
What are some examples of managed IT services?
Typical examples are help desk support, 24/7 monitoring of servers and laptops, patching, endpoint and email protection, backup checks with restore tests, Microsoft 365 administration, onboarding and offboarding staff, vendor coordination and IT budgeting. Office moves, migrations and new hardware are usually projects quoted on their own.
Do you provide IT infrastructure management services?
Yes. IT infrastructure management is part of the managed agreement: servers and workstations, switches and Wi-Fi, firewalls and VPN appliances, the Microsoft 365 tenant and Azure workloads, and the backups behind them. Everything reports into 24/7 monitoring, patches follow Microsoft's monthly cycle with actively exploited fixes pulled forward, and a hardware list with end-of-support dates turns aging equipment into a budget item before it fails. Migrations and replacements are quoted as projects.
