Custom Software Development & Penetration Testing in Sacramento, CA

QUANT LAB USA combines custom software engineering with hands-on penetration testing rooted in the MITRE ATT&CK framework — founder-led delivery, a modern stack, and security-aware engineering by default. For Sacramento buyers handling constituent data, regulated health records, or supply-chain operations, that combination matters.

Sacramento's economy is anchored by state government, which pulls in a large ecosystem of gov-tech vendors building constituent portals, permitting and licensing workflows, case-management systems, and reporting dashboards — software with real accessibility and data-handling requirements that generic products handle poorly. Surrounding the capital, the Central Valley is one of the most productive agricultural regions in the world, and the ag-tech operators serving it need field operations, supply-chain tracking, and grower-portal software that holds up in the field. And the region's health and care sector — health systems, clinics, and care providers across Sacramento, Roseville, and Folsom — generates demand for HIPAA-aware intake, scheduling, and ops tooling.

Most generalist agencies sell development hours. We sell senior engineering plus genuine offensive-security capability in the same shop. Active Directory abuse paths, lateral movement, ADCS certificate abuse, Kerberoasting, and web app exploitation are in-house, not a subcontracted line item — and every line of software we ship is reviewed against the same threat models we use on engagements. For a Sacramento gov-tech vendor under a security review, a health provider protecting PHI, or an ag operator hardening its systems, that combination is the entire pitch.

Sacramento sits three hours behind our Eastern HQ — we work your morning. Our late morning is your early morning and our late afternoon is your mid-morning, so there is a clean overlap window for standups and reviews; we run standups at 11am ET / 8am PT routinely. For engagements above roughly $25k we fly into SMF for an on-site kickoff afternoon — downtown Sacramento, Roseville, Folsom, or Davis as scope warrants. Pen testing engagements run from a secure remote infrastructure with strict source-IP allowlisting and authenticated client-side VPN tunnels for internal scope. 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 roadmap. Custom software builds are fixed-scope and fixed-price, with a weekly Friday staging URL and full handover of code and accounts at acceptance. Most Sacramento engagements close inside 4–6 weeks from kickoff to final report.
