Custom Software Development & Cybersecurity in Detroit, MI

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 an automotive supply chain where OEM security requirements are non-negotiable, that combination fits unusually well.

Detroit's economy still runs on the automobile, but the software story is bigger than the Big Three. General Motors, Ford, and Stellantis anchor a supply chain that runs thousands of Tier-1 and Tier-2 suppliers deep across Wayne, Oakland, and Macomb counties — and every one of them runs on EDI, MES, PLM, and quality-tracking systems that have to talk to the OEMs and to each other. The mobility shift has layered new demand on top: autonomous and connected-vehicle work, telematics and fleet platforms, and a research corridor anchored by the University of Michigan in Ann Arbor and the American Center for Mobility. Detroit's downtown resurgence, led by Rocket Companies and a growing tech and fintech base, adds yet another layer of software demand. Across all of it, operations tooling, supplier portals, and integration work are constant needs.

Detroit 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 MES or PLM 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 Detroit-region engagement, whether the buyer is an automotive supplier, a mobility-tech company, or a Metro Detroit SaaS founder.

Detroit 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 Detroit 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.
