The Runtime Blind Spot:Why Pre-Deployment Security Isn’t Enough for Cloud Production

While “shift-left” security solutions, such as those focused on posture and vulnerability scanning (including CSPM, ASPM, DSPM, and CIEM), effectively prevent vulnerabilities before deployment, they create a significant “runtime gap” where active threats can operate undetected in production cloud environments.

The cloud security landscape in 2025 continues to deteriorate despite widespread adoption of shift-left securitypractices. Current data reveals that 82% of data breaches now involve data stored in the cloud, with 75% increasein total cloud environment intrusions from 2022 to 2023. 

This highlights a fundamental problem: solutions focusedon pre-deployment security through static analysis and configuration scanning miss sophisticated threats, zero-day vulnerabilities, and advanced attacker techniques that emerge once applications are deployed.
