Why It Matters for AI Governance
Tamper-evident logging ensures that audit trails cannot be silently modified after the fact. Each event's hash depends on the previous event, creating a chain that breaks visibly if any entry is altered or deleted.
How CrewCheck Handles This
CrewCheck's LLM gateway applies tamper-evident logging-related controls at the request boundary. Every AI call passes through detection, policy evaluation, and audit logging — ensuring that tamper-evident logging is addressed consistently across all teams and providers.
The governance dashboard provides real-time visibility into tamper-evident logging events, with drill-down capabilities for compliance officers and exportable evidence for auditors.
