Custom Software Development & Cybersecurity in Cincinnati, OH

QUANT LAB USA pairs custom software engineering with hands-on penetration testing rooted in the MITRE ATT&CK framework — not just selling development hours. For a CPG-and-fintech economy where supply chains and payment data are mission-critical, that combination fits unusually well.

Cincinnati has a corporate density that belies its size. Procter & Gamble anchors a global consumer-goods ecosystem, and Kroger runs one of the largest grocery operations in the country from downtown — both surrounded by the agencies, suppliers, logistics firms, and data-and-analytics vendors that orbit them. The financial-services base is just as serious: Fifth Third Bank and Western & Southern are headquartered here, and a growing fintech and payments scene has grown up around that capital and talent. Manufacturing across Hamilton and Warren counties and into Northern Kentucky rounds out the picture, alongside healthcare systems and a strong university presence. Each of these sectors generates demand for trade-promotion tooling, supply-chain dashboards, payment infrastructure, and custom CRMs that vertical SaaS cannot handle cleanly at scale.

Cincinnati has plenty of staffing firms and enterprise consultancies. What is harder to find is a founder-led shop that ships modern web applications, builds the integration layer between legacy ERP and POS systems and new tooling, and runs credible offensive security engagements — all under one roof. That is what we offer. Active Directory abuse paths, lateral movement, ADCS certificate abuse, Kerberoasting, web app exploitation — that is in-house capability, not a subcontracted line item. And every line of software we ship is reviewed against the same threat models we use on offensive engagements.

QUANT LAB USA is a founder-led shop with a track record of shipping production software and running full-scope security engagements. Our pen testing work includes an end-to-end internal Active Directory assessment for a regional financial-services firm — eleven attack modules, every finding mapped to a MITRE ATT&CK technique, the full attack chain from standard user to Domain Admin documented with screenshots and timestamps. The client passed their compliance audit on the first attempt. That is the same methodology we apply to every Cincinnati-region engagement, whether the buyer is a consumer-brand supplier, a payments company, or a Greater Cincinnati SaaS founder.

Cincinnati runs on Eastern Time, the same as our Macon, Georgia headquarters, so we share the entire business day — no awkward windows for standups, reviews, or same-day questions. Most engagements start with a 60-minute scope by video. For engagements above roughly $25k we travel to Cincinnati for an on-site kickoff and for internal pen tests that require physical network access. Build cycles run weekly with a Friday staging URL, written notes, and the next-week plan. Pen test reports are delivered in two formats: a technical deliverable with reproduction steps and remediation detail for the security team, and a board-readable executive summary with a prioritized remediation roadmap. Fixed-scope, fixed-price proposals on most engagements; full code, database, and infrastructure handover at acceptance.
