Web App Pentest in San Francisco, CA
San Francisco is the most technical pentest buyer market in the country. Every founder is one degree from an ex-FAANG security engineer. Every CTO has read a pentest report before. Generic engagements that lean on scanner output die fast on the technical screen.
The problem with off-the-shelf pentest in San Francisco
Bay pentest buyers see through scanner-driven engagements fast. The competition is in-house security teams and ex-FAANG consultants. The partner that wins has to demonstrate engineering depth alongside the security expertise.
Real web app penetration testing means manual application-layer attack against the actual workflow — authentication, authorization, IDOR, business-logic, payments, and SSO surfaces — with findings mapped to MITRE ATT&CK and OWASP ASVS. For San Francisco buyers specifically, that means engagements shaped for peer-credible senior-engineering web app pentest.

How we work remote from Georgia
QUANT LAB USA is founder-led from Macon, Georgia. William Beltz runs every pentest engagement from scoping through report walkthrough. Kickoff is a structured scoping session; active testing window is fixed up front; report walkthrough is on the call calendar from week one.
For San Francisco buyers, that means full Eastern-time overlap, fixed-scope contracting, and on-site work when scope warrants. Book a scope call to walk through your app and get a written estimate.
