Custom Software Development & Penetration Testing in Buffalo, NY

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 — and we build the kind of practical, durable systems Buffalo's health and manufacturing buyers actually need.

Buffalo's economy has two strong engines. The health and life-sciences sector, centered on the Buffalo Niagara Medical Campus and Roswell Park, has driven a genuine downtown resurgence and needs intake, scheduling, and clinical operations tooling built with real data discipline. Advanced manufacturing remains a regional backbone across Erie and Niagara counties — firms that need inventory and traceability systems, MES integrations, supplier portals, and modernization of aging line-of-business software. Around those anchors sits a practical base of family-owned and mid-market firms, plus a growing SaaS scene supported by the University at Buffalo, all needing custom software that off-the-shelf products do not solve cleanly.

Most generalist agencies cannot credibly speak to penetration testing methodology, and they often treat security as an afterthought. We do not. 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 Buffalo manufacturer modernizing operations, or a health-system-adjacent team preparing for a security review, that combination of build capability and security depth is the entire pitch.

Buffalo 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 Buffalo Niagara is about 2.5 hours, and we plan working sessions in downtown Buffalo, Amherst, or on the Medical Campus 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, with a full handover of code, database, hosting accounts, and architecture documentation at acceptance.
