IT Consulting in Manhattan
NetSys provides IT consulting to businesses in Manhattan: written assessments, roadmaps with real numbers, cloud and Microsoft 365 migrations, network designs, compliance programs and a virtual CIO who stays for the quarterly review. Engineers since 1998, not a sales deck. Our office is at 1 Prospect Park SW in Brooklyn, so Park Slope to the Financial District is 25 minutes and to Midtown 35 to 45 by subway, which is how most Manhattan site visits happen; engineers come to you for the work that needs hands, and monitoring and help desk run remotely around the clock. Most clients run between 10 and 75 seats, and every agreement is month to month.

How IT consulting is delivered in Manhattan
Our office is at 1 Prospect Park SW in Brooklyn, so Park Slope to the Financial District is 25 minutes and to Midtown 35 to 45 by subway, which is how most Manhattan site visits happen; engineers come to you for the work that needs hands, and monitoring and help desk run remotely around the clock. The buildings decide a lot of the design. Pre-war office buildings from the Garment District to Wall Street have one carrier in the riser more often than not, landlords control riser access and after-hours work windows, and shared-floor and co-working leases mean the network under your staff is somebody else's, which changes how endpoint security and remote access have to be built. The carriers we see most in Manhattan are Verizon Fios, Spectrum Business, Lightpath and Crown Castle fiber, and the failover design starts with which of them actually reach your building.
Who IT consulting in Manhattan is built for
Most of our Manhattan work sits in Midtown, the Financial District, Hudson Yards, the Flatiron District and the Upper East Side: law firms on iManage, hedge funds and family offices on Bloomberg Terminal, wealth managers and RIAs on Orion, accounting firms on Thomson Reuters CS Professional Suite, agencies and media companies on HubSpot, and real estate and property managers on Yardi Voyager. Each carries its own compliance load, which the section below covers, and each has a line-of-business vendor we coordinate with rather than work around. Companies with an internal IT person fit too; in that case we supply the monitoring, the security stack and the after-hours coverage behind them, and they keep their projects.
What tends to go wrong in Manhattan
Two things shape the continuity design here. First, the weather and the grid: the outages here are a cut riser, a failed building circuit or a Con Edison vault fire, so a second carrier or wireless failover and off-site backups do more than any storm plan. Second, the attacks that actually land locally are ordinary ones, and the public record shows how they go: the June 2021 intrusion into the New York City Law Department's systems, disclosed by the city, which traced back to a single account without multifactor authentication. The controls in the next section are the ones that would have changed those stories.
IT Consulting in Manhattan: what NetSys delivers
Know what you have
- Discovery across every server, cloud tenant, device, circuit and contract, written up in IT Glue so it stays current
- Risk register with the ten findings that matter most, each with a fix, an owner and a cost
- Licensing audit of Microsoft 365, line-of-business software and security tools, with money found in seats nobody uses
- Rapid7 InsightVM scan of the internal and external footprint so the roadmap starts from measured exposure
Decide and build
- Cloud strategy with real numbers: keep, refresh or migrate, for each workload, with Azure and Microsoft 365 sized from your data
- Microsoft 365 architecture: Entra ID, Conditional Access, Intune, SharePoint information design and Exchange Online, in that order
- Office moves and build-outs specified from the floor plan: cabling, Cisco Meraki networking, Wi-Fi, failover and building access
- Security programs designed to the framework you are measured against, with the evidence an auditor or insurer will ask for
Keep it honest
- Virtual CIO reviews each quarter, with a written roadmap, a budget and a list of what changed
- Vendor management for the decisions that involve a CRM, ERP, EHR or practice-management vendor
- Due diligence for acquisitions and leases, so surprises show up in the report rather than after closing
- Month-to-month terms, with consulting priced by the project or by the review rather than by the hour
A 52-person hedge fund or family office in the Flatiron District
The specific engagements behind this profile are under NDA, so it is written as a generalization rather than a named client. Our published, client-approved outcomes are in case studies.
A 52-person hedge funds and family offices in the Flatiron District facing a decision: the server running Bloomberg Terminal is seven years old, the vendor has quoted a hardware refresh, and a cloud provider has quoted the opposite. The business is moving to a new floor and the landlord needs a network drawing next week. Nobody in the business can compare the two on the same basis, the Microsoft 365 tenant is licensed on plans nobody chose deliberately, and the lease has a network-drawing clause the landlord is now enforcing.
- A written security program mapped to the framework in play, with the control, the evidence and the owner listed for each requirement
- Project plan with a named engineer, acceptance checks for each phase and a cutover scheduled outside business hours
- A handover document that says what was built, what was decided and why, so the next person does not start from zero
- Workload-by-workload cloud assessment: each on-premises system sized for Azure, priced against a hardware refresh, and sequenced by dependency
- Cisco Meraki network design for the new floor: firewall, switching, Wi-Fi, segmentation and a cellular failover circuit, drawn for the landlord and the cabling contractor
- CRM decision run with the vendor in the room: Salesforce, HubSpot and GoHighLevel compared against the sales process the team actually follows
The company knows what it has, what it should change and what each option costs, in one document it can act on. The projects that follow have a plan, an owner and acceptance checks, and the same engineer runs the quarterly review afterwards. Month to month.
On-prem servers to Azure and OneDrive to SharePoint
Two migrations in one engagement. The client's servers lived in the office, so the business lived with the office's power, cooling and hardware age, and years of files sat in individual OneDrive accounts shared ad hoc. NetSys assessed and sized each workload and moved it into Azure with identity anchored in Entra ID, designed a SharePoint structure of sites by function and permissions by role before moving a single file, migrated the OneDrive estate into it, set backups for both platforms and took on day-to-day management. The write-up is limited to the scope delivered, with no outcome figures claimed.
Compliance in Manhattan: the SHIELD Act and what sits on top of it
If you hold personal information on a resident of New York, the New York SHIELD Act (General Business Law § 899-bb) requires any business holding private information on a New York resident, with no employee-count threshold, to keep reasonable administrative, technical and physical safeguards, and § 899-aa sets the breach-notification duty. Small businesses get a scaled standard, not an exemption. Licensed financial businesses add NYDFS Part 500 (amended in November 2023, with multifactor authentication, asset inventories and annual certification now expected of nearly every covered entity). Healthcare practices layer HIPAA on top, and advisory firms answer to the SEC and FINRA. Consulting engagements map each requirement to a control, an owner and the evidence an auditor or insurer will ask for, before anything is bought. Most firms we take over have none of it documented, which is the part that matters if you ever have to demonstrate compliance, so the documentation is built during onboarding rather than sold as a separate project.
What IT consulting costs in Manhattan
Consulting is priced by the project or by the review rather than by the hour: an assessment has a fixed price based on the size of the environment, a migration is quoted from the workload inventory, and virtual CIO advisory is a monthly figure that scales with how many reviews and decisions a year you need. What moves the number is the number of systems and sites, the compliance standard in play and whether we are also managing the environment afterwards. Every quote is written from discovery, and the terms run month to month.
Who this fits, and who it does not
Best fit: 10 to 150 employees, a decision on the table that involves cloud, an office move, an acquisition, a compliance program or a system nobody trusts, and leadership that wants options with numbers rather than a sales deck.
Not a fit: businesses looking for staff augmentation by the hour, or projects where the outcome has already been decided and only a signature is wanted. We consult to reach the right answer, which sometimes means telling you not to buy something.

IT Consulting in Manhattan: FAQs
What does an IT consulting engagement in Manhattan look like?
It starts with discovery of every system, account, vendor and risk, produces a written assessment and roadmap with costs, and then either ends there or continues into the projects the roadmap calls for and a quarterly virtual CIO review. You get findings in writing at every stage, and the engineer who did the assessment runs the projects.
Can you help us choose between Microsoft 365 and Google Workspace?
Yes, and the answer depends on the applications your team actually uses, the security controls you need and whether you can mix license tiers. We run the three-task trial described in our comparison guide, price both on the same basis and write up a recommendation with the migration effort included.
Will you work with our line-of-business software vendor?
Yes. CRM, ERP, EHR and practice-management decisions are coordinated with the vendor, whether that is Salesforce, HubSpot, GoHighLevel, NetSuite, Epic or Clio. We handle the infrastructure, identity and integration side and hold the vendor to the application side, so no question falls between the two.
Do you have an office in Manhattan?
Our office is at 1 Prospect Park SW, Suite 6E, Brooklyn, NY 11215, and Park Slope to the Financial District is 25 minutes and to Midtown 35 to 45 by subway, which is how most Manhattan site visits happen. Engineers come to you for anything the help desk cannot fix remotely, and monitoring runs around the clock from Brooklyn. Every agreement is month to month.
Does the NY SHIELD Act apply to a small business?
Yes. It applies to any business holding private information on a New York resident, with no employee-count threshold. Small businesses get a scaled standard, meaning safeguards appropriate to their size, but not an exemption, and the breach-notification duty under § 899-aa applies to everyone.
