Penetration Testing in St. Louis
Web application, network, API and cloud penetration testing for St. Louis, MO businesses — delivered by a human-led AI agent swarm that tests every endpoint in parallel, not a sample that fits a time budget.
Ranked findings with proof-of-concept evidence, remediation guidance your engineers can act on, a compliance-ready report, and a retest included. Serving St. Louis and the wider Greater St. Louis area.
Penetration testing for St. Louis businesses
Security Arsenal runs penetration tests for organisations across St. Louis, MO and the wider Greater St. Louis area — including Clayton, Belleville IL, O'Fallon, St. Charles. Testing is delivered remotely, so a St. Louis engagement runs on the same timeline and the same price list as one anywhere else in Missouri.
Most St. Louis 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 healthcare and finance 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 St. Louis
Scoped to what you actually run — nothing tested that you have not authorised in writing.

Full OWASP Top 10, authentication and session flaws, and business logic abuse against the applications your St. Louis customers actually use.
External & Internal Network
Perimeter attack surface, exposed services, credential attacks, Active Directory escalation and realistic lateral movement across your St. Louis environment.

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 St. Louis clients receive
Four deliverables on every engagement — not a raw findings dump.
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.
A swarm tests St. Louis 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 supervised swarm of specialised AI agents — recon, exploitation, business logic auditing and zero-day research — against every endpoint at once, then a certified human pentester validates every finding, kills false positives, and chains the survivors into real attack paths.
