IT Support for Professional Services Firms in Brooklyn, NY
Consultancies, agencies, research shops and advisory firms fill Downtown Brooklyn office floors, DUMBO lofts and Navy Yard suites, and most now work hybrid. NetSys runs their laptops, Microsoft 365, security and client-facing compliance from our Park Slope office, so a firm can answer a client's security questionnaire truthfully and still get an engineer in the door when it needs one.
The short answer
NetSys provides IT support and managed IT for professional services firms in Brooklyn, including consulting, marketing, research and advisory practices. That means Intune-managed laptops that work from home, a coworking desk or the office, Microsoft 365 with Conditional Access, ThreatDown managed detection and response, email security, backups, and the documentation clients ask for in security questionnaires and contract reviews. Engineers work on-site and remotely from our Brooklyn office, 10 to 30 minutes from most of the borough's business districts. Pricing is per user per month, set after an assessment, on a month-to-month agreement.

What changes for a professional services firm in Brooklyn
Brooklyn's office economy grew up around what local development groups named the Brooklyn Tech Triangle: Downtown Brooklyn, DUMBO and the Brooklyn Navy Yard. A 2022 report by HR&A Advisors counted about 46,000 tech jobs in the borough by 2021, and around them work the consultants, agencies, researchers and advisers who serve Brooklyn companies and Manhattan ones across the river. The office market has changed since 2020. PwC and the Urban Land Institute put Downtown Brooklyn's office vacancy at 15.1 percent in the second quarter of 2025, up from 5.4 percent in early 2020, as firms gave up space and went hybrid. In practice that means smaller suites, coworking memberships, staff spread across apartments in Brooklyn, Queens and New Jersey, and laptops that are the office. It also means clients, especially banks, insurers and investment advisers, send long security questionnaires before they sign, and a firm with no IT department still has to answer every line accurately.
On-site and remote support for hybrid Brooklyn offices
A hybrid firm's IT problems are mostly remote by nature: a partner whose laptop will not connect at a client site, a new hire who needs access by Monday, a Teams Room that will not join a call. Our help desk takes those first, and critical issues get a phone call back within ten minutes. 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. Engineers come to the office from Park Slope, about ten minutes to Downtown Brooklyn and 15 to 20 to DUMBO, for jobs that need hands: conference-room audio and video, new desks and docks, a firewall or Wi-Fi refresh, a move into a smaller suite or a laptop handout day for a new team. Laptops for remote hires ship to their homes enrolled in Windows Autopilot, so they sign in and work on day one.
Client security questionnaires and how to answer them
Most professional firms meet security requirements through their clients rather than a regulator. A bank, insurer or adviser sends a questionnaire such as the Shared Assessments SIG or the Cloud Security Alliance's CAIQ, or a page of contract terms, asking whether the firm uses multifactor authentication, encrypts laptops, monitors endpoints, trains staff, tests backups, has an incident response plan and removes access when people leave. The worst answer is a yes that is not true. We put the controls in first: Entra ID Conditional Access and multifactor sign-in, Intune encryption and compliance policies, ThreatDown managed detection and response, Barracuda email protection, KnowBe4 training, Keeper for shared passwords and Datto or Veeam backups. Then we keep the evidence in IT Glue and help you draft accurate answers, so the next questionnaire starts from documented facts. Firms asked for a formal attestation can work toward SOC 2 readiness.
Account takeover, AI tools and the files clients trust you with
The usual way into a professional firm is a stolen Microsoft 365 password. With one consultant's account, an attacker can read client correspondence, set a hidden forwarding rule, send an invoice with new bank details and reach shared folders. Multifactor authentication stops most of that, and Conditional Access blocks sign-ins from unmanaged devices and unexpected countries. Client files need the same care: SharePoint sites per client or engagement, permissions by role, external links that expire, and data loss prevention rules that warn before a spreadsheet of client data leaves the firm. AI tools raise the same question from a new angle, which is where client data goes. Before turning on Microsoft Copilot, we fix oversharing in SharePoint and Teams so the assistant surfaces only what each person should see. NetSys has handled more than 30 ransomware incidents over three years and restored every one, and clients with a recovery plan were working again in under a day.

Rules and client requirements for Brooklyn professional services firms
NY SHIELD Act (GBL 899-bb)
Any firm holding New Yorkers' private information, which includes its own employees' records, must keep reasonable safeguards. The statute's examples include designating someone to coordinate the security program, training staff, assessing risks, selecting service providers that can protect the data and requiring that by contract, and disposing of information by erasing electronic media so it cannot be read. Requirements scale for small businesses, defined by headcount, revenue or assets. A breach starts a 30-day clock under section 899-aa for notifying affected residents.
NYDFS 23 NYCRR 500.11 (third-party service providers)
Banks, insurers and other firms licensed by the Department of Financial Services must keep written policies for the security of systems and nonpublic information that third-party service providers can reach. Those policies address due diligence and contract terms, including the provider's access controls and multifactor authentication, encryption in transit and at rest, and notice to the regulated firm of a cybersecurity event. A Brooklyn consultancy that serves those firms is the third-party provider, and the questionnaires and contract clauses it receives come straight from this rule.
SEC Regulation S-P (amended 2024)
Investment advisers and broker-dealers covered by the amended rule must have policies reasonably designed to make their service providers protect customer information and notify them as soon as possible, and no later than 72 hours, after becoming aware of a breach. Larger firms had to comply by December 3, 2025 and smaller ones by June 3, 2026. A research, marketing or operations firm working for advisers should be ready to commit to that window and to show how it would detect a breach in time.
SOC 2 reports
SOC 2 is not a law but an attestation report on a service organization's controls, issued by an independent CPA firm against the AICPA's Trust Services Criteria for security, availability, processing integrity, confidentiality and privacy. A Type 1 report evaluates the design of controls as of a specific date; a Type 2 report tests whether they operated effectively over a period. Larger clients sometimes ask for one instead of a questionnaire. We build and run the technical controls and gather the evidence, and the CPA firm performs the examination.

Professional Services Firms in Brooklyn: FAQs
Who provides IT support for professional services firms in Brooklyn?
NetSys does, from its only office, in Park Slope. We run IT for consulting, marketing, research and advisory firms: laptops managed through Intune, Microsoft 365 and Teams, security monitoring, email protection, backups and the documentation clients ask for. You get a dedicated account manager with a real cell number and engineers who can reach Downtown Brooklyn or DUMBO quickly when hardware or a conference room needs attention. Agreements are month to month, and 98% of clients stay with us.
What does IT support cost for a professional services firm in Brooklyn?
Managed IT is priced per user per month after an assessment, and we do not publish fixed prices. For a professional firm the fee moves with headcount, the number of devices per person, how many offices or coworking locations you use, how much client compliance work is involved, such as questionnaires, SOC 2 readiness or a Regulation S-P contract, and whether you want Copilot or other AI tools set up. One-off work such as an office move or a tenant migration is quoted separately.
How do you help Brooklyn consulting firms answer client security questionnaires like the SIG or CAIQ?
First we make the answers true, then we help you write them down. We map the questionnaire to your actual controls, close the gaps with Conditional Access, encryption, endpoint monitoring, backups and training, and store screenshots, policies and reports in IT Glue as evidence. When the next questionnaire arrives, we draft the technical answers and you review and sign them. Where a question goes beyond IT, such as insurance limits or legal terms, we flag it for your partners rather than guess.
Do you support Microsoft 365 and the project and accounting software we use?
Microsoft 365 is the core of what we manage: Exchange, Teams, SharePoint, OneDrive, licensing, security settings and backups. For project management, time and billing or accounting software, we manage access, single sign-on where the vendor supports it, the devices it runs on and integrations with Microsoft 365, and we work with the vendor when the fault is inside their product. We do not claim to be the vendor of a line-of-business system, but we make sure it is secured and backed up.
Do you provide on-site IT support for professional services firms in Brooklyn?
Yes. Our engineers are based in Park Slope and come to Brooklyn offices for conference-room technology, desk and dock setups, Wi-Fi and firewall work, office moves and new-team onboarding days. Most requests from hybrid staff are solved remotely first, since the person needing help is often not in the office. Firms in coworking spaces get the same service, with the device and account security handled by us and the building network left to the operator.
Can you support a firm with offices in Brooklyn and Manhattan, or staff in several states?
Yes. A second office in Manhattan, Long Island City or Jersey City is inside the area our engineers cover on site, and the setup is the same for both: one Microsoft 365 tenant, one set of Intune policies, Meraki or Fortinet firewalls managed from the cloud, and SharePoint as the shared file home. Staff in other states are supported remotely, with laptops shipped pre-configured through Windows Autopilot and returned for wiping when someone leaves.
