Cybersecurity Companies in New York: 11 Firms Compared for 2026

If you search for a cybersecurity company in New York you get two kinds of result, and they solve different problems. The first is a global vendor with a Manhattan sales office. The second is a firm that will actually send someone to your floor in the Financial District when something breaks. This guide covers the second kind: eleven firms with a genuine presence in the New York metro, compared on what they charge, how big they are, and what they are genuinely good at.

If you read nothing else on this page, read the row that describes you. Every provider is compared in detail further down, but choosing the right category of firm matters far more than choosing between two firms in the same category.

Atlant Security editorial assessment, September 2026. This is our reading of the market, not a figure taken from any published source.

Does a New York Cybersecurity Company Need to Be in New York?

Mostly, no. Configuration review, cloud posture assessment, identity hardening, policy work and detection engineering are all done remotely now, and the best consultant for your Microsoft 365 tenant is the one who has hardened four hundred of them, not the one nearest Penn Station. Restricting a shortlist to one metro usually trades expertise for a commute you will use twice.

There are real exceptions. Physical assessments need someone in the building: badge cloning, server room access, and social engineering at a reception desk cannot be done over a video call. Trading floors and other latency-sensitive environments often require on-site work. And if you are a regulated financial institution, your examiner may expect your provider to appear in person.

The sensible filter is not distance but overlap: a provider whose working day covers yours, who can put someone on a train when an incident demands it, and who is contractually in a jurisdiction your general counsel is comfortable with. Several firms below are in New Jersey or Connecticut and serve Manhattan clients perfectly well.

What Actually Drives Security Spending in New York: NYDFS Part 500

New York has something most states do not: a detailed, enforceable cybersecurity regulation with a named regulator behind it. 23 NYCRR Part 500 applies, in the Department of Financial Services’ own words, to “any individual or organization operating under or required to operate under a license, registration, charter, certificate, permit, accreditation or similar authorization under the Banking Law, the Insurance Law or the Financial Services Law.” That is a very large share of the New York economy, and it includes many companies that do not think of themselves as financial institutions.

Three requirements drive most of the work. Section 500.4(a) states that “each covered entity shall designate a CISO”, and explicitly allows that person to be employed by a third-party service provider, while the covered entity “shall retain responsibility for compliance with this Part”. That single sentence is why the virtual CISO market exists in New York at all.

Section 500.12, as amended, is blunter than it used to be. The old text allowed risk-based authentication; the amended text says “multi-factor authentication shall be utilized for any individual accessing any information systems of a covered entity”, with a narrow exemption that still mandates MFA for remote access, cloud applications holding nonpublic information, and all privileged accounts. If you are covered and you have not finished your MFA rollout, that is the first thing to fix, ahead of anything on this page.

Section 500.17 sets the clock. A covered entity must notify the superintendent “as promptly as possible but in no event later than 72 hours after determining that a cybersecurity incident has” occurred. Seventy-two hours is not long to establish what happened, so the practical implication is that you need an incident response plan and a retainer agreed before anything goes wrong, not a phone number you look up on the day.

Beyond financial services, New York is a city of small professional firms: law practices, medical groups, architecture studios, agencies. These hold extremely sensitive information with almost no in-house IT, and they are targeted precisely because of that combination. For them the right purchase is usually a competent local managed provider plus a one-off assessment, not an enterprise platform.

The 23 NYCRR Part 500 row is taken from the New York State Department of Financial Services cybersecurity page, read on 15 September 2026. The remaining rows name frameworks rather than statutes, because for most New York companies it is a customer or an auditor, not a regulator, that forces the spend. Not legal advice.

How to Choose a Cybersecurity Company in New York

Nine of the providers below are managed IT firms with a security practice attached, and the rest fall into four or five quite different categories. That makes the selection process matter more than the shortlist. Work through these five steps in order.

1. Work out which of the things below you are buying

   A managed provider keeps your estate running day to day. A testing firm tries to break in and reports how it went. A consultancy decides what you should do and in what order. A product vendor sells you a platform somebody then has to operate. The table above says which is which.

2. Ask who fixes the problem after it is found

   A scan, an audit and a penetration test all end with a document. Somebody then has to change firewall rules, rebuild permissions, roll out multi-factor authentication and argue with a vendor about a legacy application. Ask in writing whether remediation is included, excluded, or billed separately.

3. Get the scope and the price in writing before anyone starts

   A proposal that prices security services without listing what is monitored, tested or documented is not a proposal you can hold anyone to. Ask for a fixed or capped price and an explicit list of exclusions. The price transparency panel further down shows how many of these firms publish anything at all.

4. Work out whether your driver is a regulator or a customer

   In New York these pull in different directions. A DFS examiner wants evidence of a programme. An enterprise customer wants a SOC 2 report. A card brand wants scope reduction. Buying for one and hoping it covers the others is how budgets get spent twice.

5. Ask what you keep if you leave after twelve months

   Documentation, configurations, log history, tenancy ownership. If the answer is that you keep nothing, you are not buying a security programme, you are renting one, and the renewal conversation will reflect that.

Five questions worth putting in the RFP

Atlant Security editorial, September 2026. These are the questions we would ask, based on what goes wrong in engagements we are called in to rescue.

What Cybersecurity Costs in New York

For a New York business of 50 to 250 staff, budget roughly $150 to $199 per hour for project work from a mid-market local provider, which is where most of the firms on this page sit. The security-led firms and the top specialists publish $200 to $300. The lower band, $100 to $149, generally reflects a leaner operation or a more junior team rather than a bargain.

Managed arrangements are usually priced per user per month rather than hourly, and a New York business should expect somewhere between $100 and $250 per user per month for a managed package with a genuine security tier, depending on how much is included. Minimum engagements on this page range from $1,000 to $10,000, which is a useful signal in itself: a $10,000 floor means a structured programme, a $1,000 floor means they will take a small bounded job.

A fixed-price security audit generally runs $8,000 to $35,000 depending on scope and headcount. For a covered entity under Part 500 that has never had an independent assessment, that is the cheapest way to find out how exposed you are before a regulator or an attacker tells you.

Frequently Asked Questions: Cybersecurity Companies in New York

Which cybersecurity companies are actually based in New York?

Of the firms on this page, CyberDuo, Net at Work, M6iT, Advanced Computer Technologies, RCS Professional Services and CTS all list New York City locations, and Bit by Bit has a New York office alongside its Massachusetts one. eMazzanti is across the river in Hoboken, New Jersey, and Integris and CompassMSP are multi-office national providers with New York coverage. Atlant Security works remotely with clients in 14 countries.

Does NYDFS Part 500 apply to my company?

It applies to any entity operating under a licence, registration, charter, certificate, permit, accreditation or similar authorisation under New York Banking Law, Insurance Law or Financial Services Law. That covers far more than banks: insurance agencies, mortgage brokers, money transmitters, licensed lenders and many fintech companies are included. If you are unsure, that is a question for counsel rather than for an IT provider.

Can we outsource the CISO role and still comply with Part 500?

Yes. Section 500.4(a) explicitly permits the CISO to be employed by an affiliate or a third-party service provider. The regulation is equally explicit that the covered entity retains responsibility for compliance, so outsourcing the role does not outsource the accountability.

How quickly do we have to report a breach in New York?

Part 500.17 requires notice to the superintendent as promptly as possible and no later than 72 hours after determining that a cybersecurity incident has occurred. Because the clock starts on determination, having a tested plan that reaches a determination quickly matters as much as the reporting itself.

What does a cybersecurity company cost in New York?

Published hourly rates among the firms on this page run from $100 to $300, with most of the mid-market clustering at $150 to $199. Minimum engagements range from $1,000 to $10,000. A fixed-price independent audit typically runs $8,000 to $35,000 depending on scope.

Should we hire a managed provider or a consultancy?

They solve different problems. A managed provider keeps the estate running and answers the phone. A consultancy decides what should change and in what order. If you do not yet know which you need, buy an assessment first; it is the cheapest purchase and it tells you which of the other two to make.

We already have an MSP. Is that enough for a DFS examination?

Usually not on its own, and the reason is what an examination asks for. A managed provider keeps the estate running and can implement controls competently. An examination asks you to evidence a programme: what you decided, why, who owns it, and what you did about the gaps. That is a different artefact, and it is your responsibility as the licensee rather than your provider’s. Most DFS licensees end up with the managed provider for operations and someone independent for the evidence.

We are a SaaS company. Do we need an MSP or a consultancy?

Different purchases. A managed provider keeps your corporate estate running. A consultancy decides what to fix and in what order, which is what a SOC 2 or enterprise questionnaire actually tests. Most New York SaaS companies eventually need both, and buying them in the wrong order is the most common expensive mistake in this market.
