Compliance frameworks — SOC 2, ISO 27001, PCI-DSS, HIPAA — require demonstrable evidence that security controls are in place and operating continuously. An audit trail is the continuous, tamper-evident record of who did what to which system and when. In cloud-native environments, audit trails span Kubernetes API audit logs, cloud provider CloudTrail/AuditLog, pipeline execution logs, and Vault audit logs. The challenge is aggregating and correlating these sources into a coherent compliance evidence package.

🏏 Think of it like cricket: A batting coach who only reviews a batter's technique after a tournament has already ended. The batter has played 10 matches with a flawed grip — every run scored with bad technique is harder to unlearn than if the coach had corrected it in the first net session. Shifting security left is bringing the coach into the net sessions, not the post-tournament review.
