Penetration Testing in New York City
Web application, network, API and cloud penetration testing for New York City, NY businesses — a real black-box attack run by an AI agent swarm and directed by an experienced tester, not a scan with a report template on the front.
Ranked findings with proof-of-concept evidence, remediation guidance your engineers can act on, a compliance-ready report, and a retest included. Serving NYC and the wider New York metro area area.
Penetration testing for New York City businesses
Security Arsenal runs penetration tests for organizations across New York City, NY and the wider New York metro area area — including Newark, Jersey City, Yonkers, White Plains. Testing is delivered remotely, so a NYC engagement runs on the same timeline and the same price list as one anywhere else in New York.
Most New York City clients come to us for one of three reasons: a compliance deadline (SOC 2, PCI DSS, HIPAA), a customer security questionnaire that demands a recent third-party test, or a cyber-insurance renewal. All three need the same thing — a real test with evidence, not a scanner export with a logo on it.
Our finance and law clients in the region typically start with an external network and web application test, then add internal network or cloud scope once the perimeter is clean.
What we test in NYC
Scoped to what you actually run — nothing tested that you have not authorised in writing.
Web Application
Full OWASP Top 10, authentication and session flaws, and business logic abuse against the applications your NYC customers actually use.
External & Internal Network
Perimeter attack surface, exposed services, credential attacks, Active Directory escalation and realistic lateral movement across your New York City environment.
Cloud (AWS / Azure / GCP)
IAM misconfiguration, storage bucket exposure, serverless attack surface, container escape paths and service account abuse.
API & AI-Assisted Deep Testing
REST, GraphQL and SOAP APIs — IDOR/BOLA, mass assignment, rate-limit abuse — plus zero-day research against custom code where scoped.
What New York City clients receive
Five deliverables on every engagement — not a raw findings dump, and you are covered while you work through them.
Technical Report
CVSS-scored findings with proof-of-concept evidence, affected assets, and step-by-step remediation.
Executive Summary
Business-risk framing your leadership and board can act on without a translator.
Compliance Mapping
Findings mapped to PCI DSS, SOC 2, HIPAA, OWASP and NIST references for your auditor.
Retest Included
We retest critical and high findings after you remediate and reissue the report with closure confirmed.
90-Day Protection Window
Sentinel blocking, configured from the findings we proved against you, across every protected host — free while your team fixes them.
A swarm tests NYC targets in parallel. A consultancy tests them in sequence.
A traditional engagement is rationed by hours: two testers, two weeks, and whatever they reach in that window is what you find out about. We run a swarm of specialized AI agents — recon, exploitation, business logic auditing and zero-day research — against every endpoint at once, with an experienced tester at the controls throughout — redirecting agents onto what looks promising and pushing the swarm well past where a playbook stops.
