Best Penetration Testing Companies in New York (2026)

Search “penetration testing companies NYC” and you get a mix of global consultancies with a New York address, national testing firms selling remotely, and local specialists. They are not interchangeable, and the right choice depends on what you actually need from the engagement. (Comparing beyond New York? See our national list of the best penetration testing companies.) This is a buyer’s guide to telling them apart: the firms based here, the criteria that matter, the NYC-specific angles, and the questions that separate a real testing firm from a scan-and-report shop. If you already want a local team, our NYC penetration testing page explains how we work across the five boroughs.

Penetration testing companies based in New York

These firms are headquartered in, or run their main office from, New York City. Invadel is first because this is our site; every fact about the other firms comes from their own websites, checked in September 2026, and we never quote their prices.

Firm	Where	Model	Published prices	Retest	Best for
Invadel	Manhattan (NoMad)	Boutique, senior in-house testers	Yes	Free on every test	Fixed-price testing mapped to SOC 2, PCI DSS and NYDFS 500
CYBRI	Manhattan	Manual-first testing through a PTaaS platform	Starting prices	Included above the entry tier	Startups and SaaS teams that want a client portal
BreachLock	Manhattan	PTaaS, automation plus human validation	Tiers only	1 or 2 manual retests, by plan	Platform-driven, recurring testing
Redpoint Cybersecurity	Manhattan and Long Island	Managed security and incident response, with testing	No	Per contract	Testing and incident response from one firm
Trail of Bits	New York	Security research and audit firm	No	Per contract	Deep audits of software, cryptography and blockchain code
Include Security	Brooklyn	Application security boutique	No	Per contract	Application, mobile and device assessments that need reverse engineering
Virtue Security	New York	Penetration testing boutique	No	Included	Application, network and cloud tests

“Tiers only” means plans are listed without prices for manual tests. “Per contract” means the retest terms are set in the quote, so ask before you sign. For the national platforms beyond New York, see our comparison of PTaaS companies.

Invadel. Our office is at 1178 Broadway. We publish fixed prices: web application tests from $5,200, API from $4,000, external network from $4,200, each with a free retest of remediated findings. Reports map to the framework you answer to, including NYDFS 23 NYCRR 500.

CYBRI. Founded in New York City, with offices on Broadway. It sells manual-first testing through its own PTaaS platform and publishes “starts at” tiers. See Invadel vs CYBRI.

BreachLock. A PTaaS provider with its New York office on Avenue of the Americas. It combines automated discovery with human testers and sells Standard, Extended and Extensive plans. See Invadel vs BreachLock.

Redpoint Cybersecurity. A managed security and incident response firm with a Manhattan office and a Long Island office in Uniondale; penetration testing is one service among many. See Invadel vs Redpoint.

Trail of Bits. A research-driven security firm whose audits cover application security, cryptography, blockchain and AI/ML systems. A fit when the question is whether the code itself is sound.

Include Security. A Brooklyn application security boutique covering web, mobile and IoT assessments, reverse engineering and exploit development. Assessments are sized to the codebase and attack surface.

Virtue Security. A New York boutique testing applications, networks and cloud environments, with retesting included in its assessments.

Does “local” even matter for a penetration test?

Most testing is remote, so it is fair to ask whether a New York firm offers anything a competent national one does not. For a lot of engagements, honestly, location is secondary to quality. But local presence buys three real things when they apply to you:

On-site work, when the scope needs it. Internal network testing, physical social engineering, Wi-Fi assessments, and hardware testing benefit from someone actually in the building. A local firm reaches a Manhattan office without travel cost or scheduling friction. If your scope is purely external or web, this matters less.

Fluency in the regulation you live under. A firm that works with New York financial services knows NYDFS 23 NYCRR 500 as a matter of routine: its annual penetration-testing mandate, and how findings should be presented for it. That familiarity is worth more than a zip code. Our NYDFS 23 NYCRR 500 penetration testing page shows what that evidence looks like.

Timezone and responsiveness. Same working hours, easier live coordination during testing windows, and a relationship you can build in person if a program becomes ongoing.

If none of those apply to your engagement, weight them lightly. A great remote firm beats a mediocre local one. If several apply, local presence is a genuine advantage.

The criteria that actually matter

Location aside, the same fundamentals decide whether a test is worth paying for. We cover these in depth in how to choose a penetration testing company; the essentials:

1. Manual testing by named senior testers. The single most important question. Confirm the work is genuinely manual, done by people you can name, not a vulnerability scan dressed up as a penetration test. Ask what proportion of findings come from manual work.
2. A sample report. A real firm will show you a redacted one. Look for clear reproduction steps, evidence, business-impact-based severity, and remediation guidance, not a raw scanner dump. Our sample report shows what good looks like.
3. Retesting included. Finding issues is half the job; confirming fixes is the other half. Check whether a retest is included or billed separately.
4. Scope that fits your risk, not a one-size template. The firm should ask about your environment before quoting.
5. Transparent pricing. Evasive pricing usually signals either a scan being sold at test prices, or a sales process designed to extract the maximum. Clear, scope-based pricing is a good sign.
6. The right compliance mapping. If you test for SOC 2, PCI DSS, ISO 27001, or HIPAA, the report must map findings to that framework. See our compliance testing overview.

NYC-specific angles worth raising

New York concentrates a few industries whose testing needs are distinctive:

• Financial services and fintech: NYDFS 500 applies, and banking-partner and SOC 2 requirements pile on top. Ask specifically about fintech and financial-services testing experience; our penetration testing for fintechs page lists the usual scope.
• Funds and wealth managers: SEC-registered advisers and broker-dealers answer to the amended Regulation S-P, and limited partners ask about testing in due diligence. Our pages on RIA cybersecurity and private equity cybersecurity cover advisers and family offices, and fund managers and their portfolios.
• Hospitals: New York general hospitals answer to 10 NYCRR 405.46, the state hospital cybersecurity rule, which requires an annual penetration test and vulnerability scanning on top of HIPAA.
• Law firms: NYC’s dense legal sector holds exceptionally sensitive client data and faces client security questionnaires. See penetration testing for law firms. For the engagement itself, see our law firm penetration testing services.
• Media, retail, and startups: from e-commerce (PCI DSS) to fast-moving SaaS startups that need testing aligned to rapid release cycles. Our penetration testing for startups page covers the first-test scope.

A firm that already works across these will understand your context without a long ramp-up.

The questions that separate real firms from scan shops

Bring these to any shortlist call. The quality of the answers is itself the signal:

• Who, specifically, performs the testing, and how senior are they?
• What percentage of your findings come from manual testing versus automated tools?
• Can I see a sample report?
• Is retesting included after we remediate?
• How do you scope, and how is pricing determined?
• Have you tested organizations like mine, under the same regulations?

An evasive answer to any of these, especially the first three, is a reason to keep looking.

Frequently asked questions

What does a penetration test cost in New York? Location does not change our price. Web application tests start at $5,200, API tests at $4,000 and external network tests at $4,200, fixed before work begins, with a free retest. The same prices apply to penetration testing in New Jersey, and every published price is on our pricing page.

Do we need a New York firm? Only if your scope needs on-site work, or you want a team that can be in the room. For external, web, API and cloud tests, a strong remote firm is just as good. Choose on quality first and use location as the tie-breaker.

Which firms can produce NYDFS 500.5 evidence? Ask any firm on this list the same question: will the report show penetration testing from inside and outside your information systems’ boundaries, by a qualified party, at least annually, as 500.5(a)(1) requires? Our reports are mapped to Part 500; the NYDFS 23 NYCRR 500 guide explains what examiners look for.

Where Invadel fits

We are a New York-based penetration testing firm, and we built the things this guide tells you to demand: genuinely manual testing, a sample report you can read before you buy, transparent pricing, retesting included as standard, and findings mapped to whichever framework you answer to. If you are comparing firms in NYC, we are glad to be one of the calls, and glad to answer every question above directly.

The honest summary: choose on quality first, and let local presence be the tie-breaker when your scope actually benefits from it. Whichever firm you pick, insist on manual testing, a sample report, and included retesting. Those three alone rule out most of the field.
