How GAUNTLEX Gates HIPAA/FINRA Compliance in CI

GAUNTLEX, an open-source tool by developer Sanjoy, gates HIPAA, FINRA, and other compliance requirements in CI by testing API specifications against domain-specific attack scenarios. It produces findings with CWE tags and control framework mappings, blocking merges when the Adversarial Resilience Score falls below a configurable threshold. The tool ships with playbooks for OWASP Top 10, HIPAA, FINRA, PCI DSS, and SOC 2, aiming to catch regulatory failures before code ships.

A team building a healthcare API asks an AI coding assistant to implement a patient records endpoint. The assistant produces working code — clean, well-structured, passes review. Six months later, a HIPAA audit finds the endpoint returns more PHI fields than the request actually needed. Nobody wrote a test for "is this response over-broad." Nobody thought to. That's not a hypothetical. It's the specific, named failure mode in GAUNTLEX https://github.com/sanjoy1234/gauntlex 's own HIPAA policy playbook: "PHI Disclosure — Over-Broad API Response." I want to walk through how GAUNTLEX turns regulatory requirements like this into something that actually runs in CI, instead of something a compliance team discovers during an audit that's already too late. GAUNTLEX ships five compliance domain playbooks out of the box: OWASP Top 10, HIPAA, FINRA, PCI DSS, and SOC 2 NIST SSDF and OWASP API Security are available as installable extensions . Each one is a curated set of attack scenarios specific to that domain's actual failure modes — not a generic vulnerability scanner with a different label stapled on. The HIPAA playbook's nine scenarios include things like "Emergency Access — Hardcoded Override Credentials" and "PHI Integrity — Missing Tamper Detection" — the kind of finding a generic SAST tool has no vocabulary for, because it's not a code pattern, it's a regulatory failure mode. The FINRA playbook is a different nine entirely: "SEC 17a-4 — Non-WORM Record Storage Race Condition," "AML — Structuring Detection Bypass," "Best Execution — Pricing Calculation Error" — scenarios written for people who've actually read those regulations, not reverse-engineered from a CVE database. gauntlex run --issue patient api spec.md --mode standard --domain hipaa This is the part that actually matters for a compliance review. Every finding GAUNTLEX produces carries a CWE tag and maps to real control frameworks: CONTROL MAPPINGS = { "NIST SSDF": "RV.2.2", "RV.3.1", "PW.8.1" , "OWASP SAMM": "Verification/Security-Testing/2" , "SOC2 CC": "CC7.1", "CC8.1" , "ISO 27001": "A.14.2.8", "A.14.2.9" , } That's not decoration. It's the difference between handing an auditor "we ran a security tool" and handing them a report where every finding traces to the specific control it violates — the artifact a compliance reviewer actually needs, in the format they actually work in. Here's where it stops being a reporting tool and becomes an enforcement mechanism. GAUNTLEX runs in CI with a configurable minimum Adversarial Resilience Score — 0.80 by default — and fail open: false . Below that threshold, the merge is blocked. Not a Slack notification to review later. The same mechanism that blocks a merge on a failing test suite, applied to compliance-relevant security posture. gate: minimum ars: 0.80 fail open: false That single config line is the actual point of this whole system: compliance testing that happens before code ships, gating the same pipeline everything else already gates, instead of a quarterly audit finding what a machine could have caught on day one. pip install gauntlex-ai gauntlex policy list see all available domains gauntlex run --issue your spec.md --domain hipaa --mode quick gauntlex audit lists every past run with its full compliance control mapping over a configurable window — useful the next time an auditor asks "show me your security testing evidence" and you'd rather hand over a report than a explanation.
