IT Support for Professional Services Firms in Manhattan
Consultancies, agencies, search firms and advisory practices in Manhattan sell expertise, and their clients now audit how that expertise is stored. NetSys runs the devices, Microsoft 365, security and help desk for professional services firms of 5 to 150 people, whether they lease a Midtown floor, share a co-working suite or split staff between Manhattan and other cities.
The short answer
NetSys provides IT support for professional services firms in Manhattan: a help desk for consultants and staff, laptops managed through Intune and Windows Autopilot, Microsoft 365 security, endpoint detection and response, backups, and the evidence that client security questionnaires such as the SIG and the CAIQ ask for. Manhattan is inside our on-site area, so engineers from our Brooklyn office set up offices, conference rooms and new hires in person, and most requests are resolved remotely first. Monitoring and emergency service run 24/7; the help desk is staffed seven days a week from 4 a.m. to 11 p.m. Eastern time.

What changes for a professional services firm in Manhattan
Manhattan's consulting and advisory firms have been shrinking their footprints and sharing desks. KPMG's move to Two Manhattan West is the large-scale version: its lease of roughly 450,000 square feet across a dozen floors there replaced about 800,000 square feet spread over three Midtown buildings, a cut of around 40 percent. Smaller firms make the same trade with hoteling desks, a suite in a flexible-office building or a block of seats on a co-working floor. Attendance is still partial: Kastle's barometer, as cited by the State Comptroller, showed the city's offices at 53.9 percent of their pre-pandemic occupancy in the week of September 2, 2026. That changes where IT lives. The network under a co-working desk belongs to the operator, the copier belongs to a leasing company, and what the firm truly controls is its identities, its laptops and its data. Meanwhile the clients, often banks, insurers and listed companies, send vendor risk questionnaires before signing a statement of work, and a slow or vague answer can cost the engagement. We build for both conditions at once.
On-site and remote support for Manhattan offices and co-working suites
Engineers travel from Park Slope by subway, about 25 minutes to Lower Manhattan and 35 to 45 to Midtown, for work that needs a person in the room: a new suite before move-in, conference room cameras and screens, a firewall and access points where the firm controls the network, or a group of new hires who need laptops handed over and explained. In a co-working space we work with the operator's community team instead of a building's managing agent, and we leave the operator's network alone; our job is making each device safe on it. The rest is remote. Laptops ship to consultants anywhere through Windows Autopilot, NinjaOne patches and monitors them, and the help desk answers staff directly. An account manager reachable on a real cell number keeps track of open requests and renewals.
Client security questionnaires and how to answer them
Procurement teams at large clients often send the Shared Assessments SIG, which is updated every year and comes in lighter and fuller scopings, or the Cloud Security Alliance's CAIQ, and some ask for a SOC 2 report. Most questions come down to the same controls: multifactor sign-in, managed and encrypted devices, endpoint detection, email filtering, tested backups, security training, access reviews, vendor management and an incident plan. We put those controls in place with Entra ID Conditional Access, Intune, ThreatDown, Barracuda, Datto or Veeam and KnowBe4, then keep the reports that prove them in IT Glue. When a questionnaire arrives, we draft the technical answers with your team from those records and tell you plainly where a control is missing rather than writing around it. If a client requires a SOC 2 report, our readiness work prepares the environment for the auditor.
One firm, several offices and the platforms in between
Plenty of Manhattan professional firms also run an office in another city, or keep a few people in a regional office. Each site gets the same baseline: a Meraki or Fortinet firewall managed from one console, the same Wi-Fi and guest network design and the same Intune policies, so a consultant visiting from Chicago or London signs in once and works. Time, billing and project accounting usually sit in a professional services automation system or an ERP, with a CRM for pipeline and an e-signature tool for statements of work. We set up single sign-on into those platforms, so offboarding one person closes every account, and we coordinate outages and changes with the vendors. Files live in SharePoint and Teams by client and engagement, with external sharing controlled per site, and Microsoft 365 is backed up by a separate service so a deleted engagement folder can be restored.

Rules that reach a Manhattan professional services firm
SHIELD Act safeguards, GBL 899-bb
Any business holding New York residents' private information must keep reasonable administrative, technical and physical safeguards. The Attorney General's guidance gives examples: naming someone to coordinate the program, assessing foreseeable risks, training staff, requiring service providers to protect data by contract, testing key controls and disposing of data securely. Payroll and HR records bring nearly every firm inside the statute even when the client work does not.
Breach notice within 30 days, GBL 899-aa
Notice to affected New York residents must go out within 30 days of discovering a breach, with the Attorney General, the Department of State and the State Police told as well. A firm holding private information it does not own, such as a client's employee data, must notify that client immediately and within 30 days. Since March 2025 the definition of private information includes medical and health insurance information, which matters for benefits and HR consultancies.
Clients regulated by DFS, 23 NYCRR 500.11
Banks, insurers and other DFS-licensed clients must keep written policies for third-party service providers that can reach their nonpublic information, covering risk assessment, minimum cybersecurity practices, due diligence and periodic review, and addressing multifactor authentication, encryption and incident notice. A consultancy with access to that data is one of those providers, which explains the contract clauses and questionnaires.
Clients under SEC Regulation S-P
Investment advisers and broker-dealers must now require their service providers to notify them of a breach affecting customer information within 72 hours. A firm serving that market should expect the clause in its contracts and needs the monitoring to meet it. This is general information, not legal advice.

Professional Services Firms in Manhattan: FAQs
Who provides IT support for professional services firms in Manhattan?
NetSys does, from one office in Park Slope, Brooklyn, close enough to Midtown and Lower Manhattan that our engineers work on site there routinely. Founded in 1998, NetSys runs the help desk, managed laptops and phones, Microsoft 365, security, backups and the answers to client security reviews. Engineers are Cisco and Microsoft certified, agreements are month to month and client retention is 98%. Client names stay out of our marketing.
Do you provide on-site IT support for professional services firms in Manhattan?
Yes. Engineers come from Brooklyn to set up new suites, conference rooms and printers, install firewalls and Wi-Fi where you control the space, hand over laptops to new hires and fix hardware that cannot be repaired remotely. We coordinate with the building's managing agent or the co-working operator on access. Remote support comes first for everyday requests, and severe problems such as a compromised account or a lost connection go straight to your dedicated engineer.
What does IT support cost for a professional services firm in Manhattan?
We quote per user per month after an assessment and do not publish a rate card. The figure moves with headcount and devices, how many offices and countries staff work from, the business platforms we manage access to, and how much evidence clients' security reviews require. Hardware, office fit-outs and projects such as a tenant migration after a merger are quoted separately. Agreements run month to month, so the arrangement can grow or shrink with the firm.
How do you help Manhattan consulting firms answer SIG or CAIQ questionnaires?
We start from the controls, not the spreadsheet. Once multifactor sign-in, device management, endpoint detection, email security, backups, training and access reviews are in place, each has a report in IT Glue. When a SIG Lite, a full SIG, a CAIQ or a client's own form arrives, we map its technical questions to those records, draft answers with your operations lead and attach evidence where the client asks. Questions about HR, legal or insurance stay with the people who own them.
Do you support Microsoft 365 and our time and billing system?
Microsoft 365 we run completely: accounts, licenses, Exchange Online, Teams, SharePoint, OneDrive, Intune and security settings. For time and billing, project accounting, CRM and e-signature platforms, we manage the side that touches IT: single sign-on, user provisioning and removal, browser and device requirements, integrations with Microsoft 365, and opening tickets with the vendor when something breaks. Configuration inside the application stays with your team and the vendor, and we document who owns what.
Can you support consultants who work from client sites or co-working spaces?
Yes, and most of our design assumes it. Laptops are enrolled in Intune with disk encryption and ThreatDown, sign-in requires multifactor authentication and a compliant device, and company data is reached through Conditional Access rather than an office network. Client Wi-Fi and co-working networks are treated as untrusted. If a client requires its own device or VPN, we document the arrangement and keep your firm's data separate from the client's.
