Finance IT Providers in Manhattan: 10 Best, Ranked for 2026

By Best IT MSP Editorial Team - Updated August 23, 2026 - 10 min read

The Best IT MSP editorial team maintains this directory's provider data across the US and Canada. We rank providers on verified rating and firmographic data, label paid placement, and do not sell IT services.

How we ranked these providers

Every position on this page comes from one rule, applied the same way to every firm, and it is published here before the list so you can judge it.

• Eligibility. A provider had to be tagged to finance and accounting on its own Best IT MSP listing. General managed IT firms that never mention the sector were excluded. That left 22 qualifying providers in Manhattan.
• Order. Providers are ranked by confidence-weighted rating rather than raw average. A firm's score is pulled toward the local average in proportion to how few reviews it carries, and the Manhattan average is 4.95. That is why review volume changes the order.
• Unrated firms. A provider with no published rating is listed but never placed above a rated one. Absence of evidence is not evidence.
• Paid placement. Excluded entirely. This is a merit list. Where Best IT MSP sells a Featured Partner spot it is labelled as one and kept out of the ranked order.
• Independence. Best IT MSP does not sell IT services and does not appear in its own rankings.

The figures behind the order are the verified rating and review count on each provider's profile. Nothing here is editorial preference.

Can a New York firm outsource Part 500 compliance to its IT provider?

No. The New York State Department of Financial Services stated it directly in an industry letter dated 21 October 2025: Covered Entities may not delegate responsibility for compliance with the Cybersecurity Regulation to an affiliate or a third-party service provider.

The letter was not hypothetical. DFS wrote that it had observed a trend in which some Covered Entities outsource critical cybersecurity compliance obligations to service providers without ensuring appropriate oversight and verification by Senior Governing Bodies or Senior Officers, and that it has and will continue to consider the absence of appropriate third-party risk management practices in its examinations, investigations, and enforcement actions.

What the regulation actually asks of the board

Oversight has a defined standard here. Senior Governing Bodies must have enough understanding of cybersecurity to provide a credible challenge to management's cybersecurity-related decisions, and Part 500 requires a Senior Officer or the Senior Governing Body to review and approve the firm's cybersecurity policies and procedures at least annually under Section 500.3.

Read plainly, that means a partner has to be able to ask the IT provider a hard question and judge the answer. Hiring a good provider does not discharge the duty. It changes who does the work, not who answers for it.

Which finance and accounting IT providers rank highest in Manhattan?

These are the top 10 of 22 qualifying providers, in the order the methodology above produces.

1. Setton Consulting holds 5.0 from 88 reviews, works from Manhattan, NY (Midtown / Garment District), a 10-49 person team. The deepest review record in this field and the clear leader on evidence. Midtown, in the Garment District.

2. Delaney Computer Services holds 5.0 from 64 reviews, works from Manhattan, NY (NoMad / Midtown South), a 10-49 person team. NoMad, and the second-deepest record here. The gap between first and second is real but not large.

3. M6iT Consulting holds 5.0 from 56 reviews, works from Manhattan, NY (Garment District), a 10-49 person team. Garment District, past fifty reviews, and close enough to the firm above it to belong on the same shortlist.

4. KJ Technology holds 5.0 from 48 reviews, works from Manhattan, NY (Garment District), a 10-49 person team. Also Garment District. Three of the top four sit within a few blocks of each other, which is worth knowing if on-site response time matters to you.

5. Red Key Solutions holds 5.0 from 42 reviews, works from Manhattan, NY (Midtown East / Grand Central), a 10-49 person team. Midtown East by Grand Central, on a solid record.

6. Integrated Technology Systems holds 5.0 from 40 reviews, works from Manhattan, NY (Midtown East), a 10-49 person team. Midtown East, on a review base in the same band as the firm above it, so treat five and six as close.

7. CMIT Solutions of Tribeca holds 5.0 from 34 reviews, works from Manhattan, NY (Tribeca), a 10-49 person team. Tribeca, and the first firm in the list outside Midtown. Part of a national franchise network, so ask what is delivered locally and what is delivered centrally.

8. Miles IT holds 5.0 from 28 reviews, works from Manhattan, NY (Midtown / Times Square), a 50-249 person team. The largest firm here by headcount, in the 50-249 band, on a smaller review base than the firms above it. Bench depth against evidence depth is the trade.

9. ETech 7 holds 5.0 from 22 reviews, works from Manhattan, NY (Diamond District / Midtown), a 10-49 person team. The evidence thins from here. Past twenty reviews, which is a workable base but a thinner one.

10. IN NYC IT holds 5.0 from 20 reviews, works from Manhattan, NY (Financial District), a 1-9 person team. The only firm in this top ten actually based in the Financial District, and the smallest, with fewer than ten staff. Proximity to a downtown office is a real advantage; the review base is the smallest here.

Why does DFS single out managed IT providers?

Because of what they can reach. DFS names companies that provide IT managed services and outsourced help desk services among the providers of critical services that often have a high degree of system-level access and the ability to access sensitive Nonpublic Information.

The department draws the distinction by access rather than by contract value. A provider with privileged access to a firm's Information Systems and significant amounts of Nonpublic Information presents a greater risk than one providing services that operate outside those systems. Your managed IT provider is almost always in the first category.

That is the reframing worth taking from the letter. The provider is not a vendor sitting outside the perimeter. It holds the keys, so it belongs inside your risk assessment, your annual review and your board reporting.

What should a Manhattan finance firm ask before signing?

Three questions come standard for finance, and DFS supplies the rest of the list itself.

• What evidence can you hand an examiner without us preparing it first?
• How do you handle privileged access, and who at your firm can reach our data?
• What is your notification process and timeline if you detect a breach in our environment?

The department's own due diligence list adds four that are easy to ask and hard to bluff. Ask whether the provider uses unique, traceable accounts for personnel accessing your systems and maintains audit trails meeting the requirements of Section 500.6. Ask whether it maintains and regularly tests its incident response and business continuity plans. Ask about its practices for selecting, monitoring and contracting with downstream service providers, the fourth parties. Ask whether it undergoes external audits or independent assessments, or can otherwise demonstrate in writing compliance with Part 500.

A standardised questionnaire helps gather the answers, but DFS is explicit that it does not replace judgement: qualified personnel will need to interpret the responses, ask follow-up questions and determine appropriate mitigation strategies.

What belongs in the contract, and what belongs at the end of it?

Part 500 requires written policies covering both. Section 500.11(b) obliges firms using third-party providers to develop and implement written policies and procedures that address due diligence and contractual protections.

The contract itself should address access controls including multi-factor authentication that complies with Sections 500.7 and 500.12, encryption in transit and at rest as required by Section 500.15, timely notice of a Cybersecurity Event, and representations and warranties regarding compliance with applicable requirements of Part 500. DFS also recommends terms covering where data is stored and processed, and disclosure of any subcontractors touching your systems.

Termination is the step firms forget. On exit a firm must disable the provider's access to its Information Systems under Section 500.7(a)(4), which means revoking accounts for the provider's staff and subcontractors, deactivating service accounts, and for cloud services revoking identity federation tools, API integrations and external storage access.

Then verify the data is gone. DFS advises confirming that any remaining snapshots, backups or cached datasets are deleted from the provider's systems, and warns about residual or unmonitored access points that fall outside routine access provisioning. An old jump-box account nobody closed is the classic finding.

FAQ

How were these Manhattan finance IT providers ranked?

By confidence-weighted rating. Each provider's verified rating is pulled toward the Manhattan average in proportion to how few reviews it has, so a 5.0 from 88 reviews outranks a 5.0 from 20. Only providers tagged to finance and accounting on their own listing were eligible, and paid placement was excluded.

Can we outsource NYDFS Part 500 compliance to our IT provider?

No. In an industry letter dated 21 October 2025, DFS stated that Covered Entities may not delegate responsibility for compliance with the Cybersecurity Regulation to an affiliate or a third-party service provider. The provider can do the work, but your firm answers for it, and DFS says it considers weak third-party risk management in examinations, investigations and enforcement actions.

Does Part 500 apply to a small firm?

It applies to any Covered Entity, which Section 500.1(e) defines as any person operating under, or required to operate under, a licence, registration, charter, certificate, permit, accreditation or similar authorisation under the Banking Law, the Insurance Law or the Financial Services Law. Smaller firms may qualify for limited exemptions under Section 500.19, but they must still maintain a written cybersecurity policy approved at least annually.

What did the October 2025 DFS guidance change?

Nothing, formally. DFS stated the guidance does not impose new requirements and is intended to clarify existing ones, principally Section 500.11. What it changed in practice is visibility: it set out what DFS looks for across the whole life of a provider relationship, from due diligence and contracting through monitoring to termination.

How quickly must a cybersecurity event be reported to DFS?

Within 72 hours. Regulated entities must report cybersecurity events meeting the criteria of Section 500.17(a) as promptly as possible and within 72 hours in any event, through the secure Department portal.

How often is this ranking updated?

It is regenerated from the directory's provider data, so it moves when ratings and review counts move. The date at the top of this article is the last time the underlying figures were rebuilt.
