Custom Software Development & Penetration Testing in Houston, TX

QUANT LAB USA combines custom software engineering with hands-on penetration testing rooted in the MITRE ATT&CK framework — not just selling development hours. Houston buyers expect a vendor who understands both how to build a production system and how an attacker would try to break it. We do both in-house.

Houston is the energy capital of the world. ExxonMobil's campus near Spring, Chevron, ConocoPhillips, Phillips 66, Halliburton, Baker Hughes, and SLB anchor an upstream-to-downstream ecosystem that runs on field data, production tracking, and trading workflows. The Texas Medical Center pulls together MD Anderson, Houston Methodist, Texas Children's, Memorial Hermann, and Baylor College of Medicine into the densest healthcare cluster on the planet — every one of them surrounded by practices, labs, and device vendors that need HIPAA-aware software. The Port of Houston and the petrochemical complex along the Ship Channel add a logistics and industrial layer on top. Underneath all of it sits a deep services and distribution mid-market across Harris, Fort Bend, and Montgomery counties.

Most generalist agencies cannot credibly speak to penetration testing methodology, and most security shops cannot ship production software. We do both. Active Directory abuse paths, lateral movement, ADCS certificate abuse, Kerberoasting, and web application exploitation are 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. For Houston operators running compliance programs or selling into enterprise procurement, that combination is the entire pitch.

Our pen testing track record includes a full Active Directory engagement for a regional financial services firm — an end-to-end internal assessment running eleven attack modules, every finding mapped to a MITRE ATT&CK technique, with the full attack chain from standard user to Domain Admin documented in screenshots and timestamps. The client passed their compliance audit on the first attempt and re-engaged us on a six-month cadence. That is the same methodology we apply to every Houston engagement, whether the buyer is an energy operator, a Medical Center-adjacent practice, or a logistics firm on the Ship Channel.

QUANT LAB USA is founder-led and accountable end-to-end. We ship production web and SaaS applications on a modern Next.js, TypeScript, PostgreSQL, and Docker stack, and we keep our proof generic and our references available under NDA — no name-dropping clients who did not sign up to be a marketing line.

Houston is one hour behind Georgia HQ, so our morning and your late morning overlap completely for standups and design reviews. Most engagements start with a 60-minute scope by video, followed by a fly-in for an on-site kickoff afternoon — the Energy Corridor, downtown, the Medical Center, Sugar Land, or The Woodlands. After kickoff, build cycles run weekly with a Friday staging URL, written notes, and the next-week plan. Pen testing runs from a secure remote infrastructure with strict source IP allowlisting and authenticated VPN tunnels for internal scope; internal tests requiring on-site network access are scheduled on-site for the active window with remote reporting following. We bill fixed scope on virtually every Houston engagement, and code, database, hosting accounts, and full documentation transfer at acceptance — exactly what procurement needs for ownership and audit review.
