Penetration Testing for New York Organizations
New York is the most heavily regulated security environment in the United States, and that shapes what a penetration test has to deliver here. In most markets a test is a good practice that a customer may ask about. In New York, for a large share of the economy, it is a named regulatory obligation with a signed certification behind it.
NYDFS Part 500 is the reason. It applies to entities licensed by the New York Department of Financial Services, which reaches far beyond the big banks: insurers, mortgage originators, money transmitters, licensed lenders and virtual currency businesses all sit inside it. The regulation requires annual penetration testing, and it requires senior leadership to certify compliance personally. That changes the conversation, because the person signing wants to know that the test was real, that the findings were tracked, and that the scope actually matched the systems their cybersecurity program covers.
The financial concentration also produces a distinctive adversary profile. Capital markets and asset management firms are targeted by well-resourced actors interested in position data, deal information and payment instructions rather than in disruption. Insurance carriers hold claims data and increasingly sit in the same supervisory frame. What both share is a heavy dependence on third parties: fund administrators, prime brokers, market data providers, outsourced IT, and the long list of vendors with standing access. Third-party risk is the sector's most persistent structural weakness, and Part 500 has increasingly pushed on exactly that.
Around finance sit concentrations that fail differently. Large law firms hold material non-public information on transactions before they are announced, which makes them a high-value, comparatively softer target, and their clients now routinely impose security requirements by contract. Media and advertising organizations run sprawling vendor and freelance access. The city's academic medical centers and health systems hold records under HIPAA with clinical availability consequences. And underneath all of it runs critical infrastructure, transit and utilities where availability is a public matter.
The recurring finding in New York engagements is not a weak perimeter. These organizations generally spend well. It is that the internal blast radius is larger than assumed, usually because identity sprawled across decades of systems, mergers and outsourced functions, and nobody has tested how far a single ordinary account actually reaches.
What We Test
New York engagements are scoped around your environment and, where relevant, around the regulation you report against.
External attack surface
Everything reachable from the internet: perimeter firewalls, VPN concentrators, remote access gateways, email infrastructure, public DNS, and the subdomains that accumulate across acquisitions, funds and campaign sites. AI-augmented reconnaissance continuously maps exposed assets, certificates, cloud storage and leaked credentials, and a certified operator validates what is genuinely exploitable.
Internal network and Active Directory
Usually the test that changes the conversation. We replicate what a compromised workstation or a malicious insider could achieve: privilege escalation, lateral movement, Kerberos abuse, credential harvesting, and the route from a standard user account to domain administrator. In organizations built through mergers and outsourcing, this is where the distance between business units turns out to be far shorter than the architecture diagram suggests.
Third-party and vendor access
Given how much New York work runs through external parties, we treat vendor access as an attack path in its own right: standing vendor VPN access, guest identities in cloud tenants, outsourced administration accounts, and the dormant credentials left behind when a relationship ended. This is frequently where a Part 500 program looks strongest on paper and weakest in practice.
Web applications and APIs
Client portals, trading and reporting platforms, claims systems, patient portals, publishing and advertising platforms, and the integrations between them. We test against the OWASP Web Security Testing Guide and the OWASP API Security Top 10, covering authentication and session handling, access control across roles and tenants, object-level authorization, injection and business logic flaws.
Cloud environments
AWS, Azure and Google Cloud configuration review and exploitation: identity and access management, privilege escalation paths, exposed storage, secrets handling and the workload identities bridging cloud to on-premises. Hybrid identity between Active Directory and Entra ID gets particular attention, because it is how a cloud compromise becomes a domain compromise.
Social engineering and phishing
Targeted phishing, pretext calling and physical access testing, authorized carefully and reported without singling out individuals. Against finance and legal functions this is often the most realistic representation of how an actual incident would begin.
New York Compliance and Regulatory Drivers
NYDFS Part 500 is the defining obligation for licensed financial services entities. It requires annual penetration testing, ongoing vulnerability management, a CISO function, incident reporting within a short window, and an annual certification signed by senior leadership. It has also tightened progressively, with expectations around multi-factor authentication, asset inventory and third-party risk that testing can evidence directly.
GLBA and FFIEC expectations apply to banking and financial institutions alongside the state regime. The SEC cyber disclosure rules require public companies to assess and disclose material incidents, which has moved incident readiness onto the board agenda.
The New York SHIELD Act imposes reasonable safeguards on any business holding New York residents' private information, well beyond regulated finance, with breach notification under General Business Law 899-aa.
PCI DSS applies to card handling, SOC 2 Type II to technology and services firms selling into the enterprise, and HIPAA to health systems and affiliated practices.
How an Engagement Runs
Scoping starts with a conversation rather than a questionnaire: what you are protecting, what worries you, what evidence you need, and which regulation the report has to satisfy. Targets, timing, rules of engagement and success criteria are agreed in writing before anything is touched, including market-hours constraints where they apply.
Testing is performed by certified human operators using AI-augmented tooling for reconnaissance and coverage. Critical findings are reported the day we confirm them through an agreed channel, because a path to domain administrator is not something to hold until a report is ready.
The report carries an executive narrative your board and your CISO can act on, and technical detail your engineers can reproduce, with evidence, demonstrated impact and a prioritized remediation path. A retest of remediated items is available so findings can be shown closed rather than merely acknowledged, which is what an examiner looks for.
Why New York Organizations Choose StrikeCyber
Because the report has to survive scrutiny, and ours is written for that. Findings are validated by certified human operators rather than passed through from a scanner, with evidence and demonstrated impact attached, and scoped against the systems your program actually covers rather than a convenient subset.
AI-augmented reconnaissance and continuous attack surface validation reach coverage manual enumeration cannot. Scope and price are fixed before testing starts, and findings are prioritized by exploitability and business impact rather than raw severity score, so remediation effort goes where it reduces risk instead of where it shortens a list.
Related Services
New York organizations frequently combine a penetration test with:
- Red teaming, for full-spectrum adversary emulation against people, process and technology.
- Vulnerability assessments, for the continuous visibility that sits between annual tests.
- Maturity level assessments, for benchmarking against NIST CSF, ISO 27001 or CIS ahead of an examination or board review.
- Adversary simulation, to test whether detection and response fire against real attacker tradecraft.
