IaC Drift Detection and Runtime Guardrails for Continuous Cloud Compliance

Infrastructure as Code (IaC) is supposed to be the single source of truth. But code drifts. Configurations change in the cloud. Security groups open when they shouldn’t. A bucket loses encryption. An instance upgrades without your knowledge. This is IaC drift. And without constant visibility, you are running production blind.

IaC Drift Detection is more than scanning a repo. It runs against the actual state of your resources and compares them to the version in source control. It flags the smallest difference — tags, settings, or ephemeral changes — before they cause downtime, security exposures, or cost overruns.

Runtime Guardrails take it further. They are continuous policies that block or alert on risky actions in real time. This means drift is not just detected; it is prevented from becoming a live problem. Guardrails enforce rules like “no production changes without a PR,” “no public S3 buckets,” or “no IAM wildcard policies.” They operate at runtime, not just at deploy time, closing the gap between governance and delivery.

When IaC drift detection and runtime guardrails work together, your systems stay in sync with code, and your compliance is no longer manual. Detection tells you a change happened. Guardrails ensure risky changes never go through. Combined, they deliver operational control without slowing down engineering velocity.

Every engineering team with real cloud scale faces this. Manual checks are too slow. Periodic audits are too late. The only viable solution is automated drift detection tied directly to runtime guardrails — fast, continuous, enforceable.
