Custom Software Development & Penetration Testing in Philadelphia, PA

QUANT LAB USA pairs custom software engineering with hands-on penetration testing rooted in the MITRE ATT&CK framework. We are founder-led, US-based, and security-aware from day one — which is exactly what Philadelphia's healthcare and university buyers require from a vendor.

Philadelphia's economy is built on eds-and-meds. The hospital and health-system layer — Penn Medicine, Jefferson, Children's Hospital of Philadelphia, Temple Health — plus a heavy concentration of pharma and healthcare-payer operations creates constant demand for intake, scheduling, and operations software built with real data-handling discipline. The university engine at Penn, Drexel, Temple, and Villanova feeds a steady stream of spinouts and EdTech ventures. And a growing SaaS and professional-services base across Center City, University City, and the King of Prussia corridor needs custom CRMs, billing infrastructure, and internal tooling that off-the-shelf products do not solve cleanly.

Most generalist agencies cannot credibly speak to penetration testing methodology, and a healthcare-grade buyer in Philadelphia will notice immediately. We can. Active Directory abuse paths, lateral movement, ADCS certificate abuse, Kerberoasting, web application exploitation — that is in-house capability, not a subcontracted line item. Every line of software we ship is reviewed against the same threat models we use on offensive engagements. For a Philadelphia health system facing a payer security review, or a SaaS founder preparing for a SOC 2 audit, that combination of build capability and security depth is the whole pitch.

Philadelphia sits in the same time zone as our Macon, Georgia HQ, so you get full Eastern Time overlap and same-business-day responsiveness. Most kickoffs run as a 60–90 minute video session, with an on-site afternoon for engagements above roughly 25,000 dollars — Atlanta to Philadelphia is about 2 hours, and we plan working sessions in Center City, University City, or King of Prussia as scope warrants. Build cycles run weekly with a Friday staging URL, written notes, and the next week's plan. Pen tests run from secured remote infrastructure with strict source-IP allowlisting and authenticated VPN tunnels for internal scope. Reports come in two formats: a technical deliverable with reproduction steps for engineers, and a board-readable executive summary with a prioritized remediation roadmap. Custom builds close on fixed-scope, fixed-price proposals, and the handover at acceptance is the code, the database, the hosting accounts, and the architecture documentation in one package.
