Why Audit Trails Matter

The Problem with Inadequate Logging:

  • • No Evidence Trail: Can't prove compliance during audits
  • • Deleted or Modified Records: No tamper protection for logs
  • • Incomplete Capture: Missing key events like model changes, data updates
  • • Regulatory Violations: EU AI Act requires 10-year retention, most systems default to 90 days

ATD Playbook Solution:

  • • Comprehensive Logging: All AI lifecycle events captured
  • • Tamper-Proof Storage: Cryptographic verification prevents modification
  • • 10-Year Retention: Meets EU AI Act Article 12 requirements
  • • Audit-Ready Exports: Provide evidence to regulators in minutes

Real-World Audit Failures:

Banking - Model Governance:

"Regulators asked us to prove when we retrained our credit scoring model. Our logs only go back 90 days, but the change happened 6 months ago. We had no evidence. Result: Failed audit, $2M fine."

Issue: Insufficient log retention

Healthcare - Algorithm Transparency:

"Patient filed complaint about AI diagnosis. We needed to show what data version was used, what model version, who approved it. We had none of this. Lawsuit cost us $5M plus reputation damage."

Issue: Incomplete audit trail

Regulatory Requirements for Audit Trails:

•
EU AI Act Article 12: High-risk AI systems shall keep logs automatically generated. Logs shall enable the demonstration of conformity and must be kept for at least 10 years. Logs must include operation period, reference database, and persons who access the system.
•
EU AI Act Article 16: Providers must keep technical documentation and logs. Authorities can request these at any time.
•
ISO 42001 Section 8.2: Organization shall keep records to provide evidence of conformity to AI management system requirements.

Why TrustRail is Different

AI-specific audit trails vs generic system logs

Capability Generic Logging Systems TrustRail (ATD Playbook)
Event Coverage ❌ Generic system events
Miss AI-specific events (model updates, bias tests) 		✓ AI lifecycle events
Training, deployment, testing, monitoring, updates
Retention Period ❌ 30-90 days default
Violates EU AI Act 10-year requirement 		✓ 10-year retention built-in
EU AI Act Article 12 compliant
Tamper Protection ❌ Logs can be deleted/modified
No cryptographic verification 		✓ Immutable, cryptographically verified
Blockchain-backed integrity
Audit Exports ❌ Raw log files
Requires manual formatting for auditors 		✓ Audit-ready reports
PDF reports with chain of custody
Regulatory Mapping ❌ No compliance context
Logs don't map to regulatory requirements 		✓ Events tagged to compliance checks
EU-013, EU-014, ISO-013, ISO-014 mapped
Setup Time ❌ 3-6 months custom integration
Build AI event taxonomy from scratch 		✓ 1-2 weeks with professional setup
Pre-built AI event library
