92
Rules
What are these 92 rules?
Rules built from real payment integration failures across 7 categories:
- Hardcoded secrets and API key exposure
- Missing webhook signature validation
- Idempotency and duplicate charge prevention
- Raw card data and PAN logging
- TLS and encryption requirements
- PCI DSS 4.0 requirement mapping
- Processor-specific integration patterns
These rules keep your integration compliant and out of scope for costly PCI audits.

Step 1 — You scan
Smartriarch analyzes your payment code in context
92 rules · real production patterns
Learn more ›
92 rules built from real production vulnerabilities — not generic security checklists. Findings are mapped to PCI DSS requirements and tied to your specific processor and stack.
From our pre-launch scan of 30 open-source repositories: 53% had at least one critical violation
Step 2 — Smartriarch learns
Your patterns join an anonymized dataset of real SaaS builds
Scan results · contracts · checklist patterns
Learn more ›
Anonymized and aggregated — never your raw code. Smartriarch learns which integration patterns cause the most compliance failures and where SaaS teams get stuck.
From our validation testing: 5 real production codebases · 168 real findings
Step 3 — Everyone benefits
Continuously improving accuracy
A system that gets more accurate over time
