Compliance Overview
Bindy operates in a regulated banking environment and implements comprehensive security and compliance controls to meet multiple regulatory frameworks. This section documents how Bindy complies with SOX 404, PCI-DSS, Basel III, SLSA, and NIST Cybersecurity Framework requirements.
Why Compliance Matters
As a critical DNS infrastructure component in financial services, Bindy must meet stringent compliance requirements:
- SOX 404: IT General Controls (ITGC) for financial reporting systems
- PCI-DSS: Payment Card Industry Data Security Standard
- Basel III: Banking regulatory framework for operational risk
- SLSA: Supply Chain Levels for Software Artifacts (security)
- NIST CSF: Cybersecurity Framework for critical infrastructure
Failure to comply can result in:
- 🚨 Failed audits (SOX 404, PCI-DSS)
- 💰 Financial penalties (up to $100k/day for PCI-DSS violations)
- ⚖️ Legal liability (Sarbanes-Oxley criminal penalties)
- 📉 Loss of customer trust and business
