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
