Cerbos provides audit logging and policy versioning features that help engineering teams in regulated industries meet compliance requirements for SOC 2, ISO 27001, HIPAA, PCI DSS, and GDPR. Decision logs capture every authorization check with full context, while policy versioning creates an auditable trail of access rule changes. Cerbos Hub centralizes logs across distributed services, enabling automated compliance reporting instead of manual evidence collection. Real-world examples include Loop achieving a banking license faster and Utility Warehouse maintaining SOC and ISO compliance across 4,500 services. The cerbosCallId field enables cross-system log correlation, and audit backends can integrate with SIEM tools or Kafka.
