Cloud misconfigurations still cause saying-it-out-loud 99% of cloud security failures, but in 2026 the mistakes have mutated. Today’s breaches are less “oops, public bucket” and more over-privileged identities, sketchy SaaS integrations, forgotten test environments, and dangerously helpful defaults in AI and Kubernetes. This talk introduces a modern hierarchy of cloud misconfigurations based on late-2025 and early-2026 breach data, then flips the script from post-incident cleanup to pre-deployment prevention using Policy as Code (PaC). Instead of finding problems after attackers do, we stop insecure resources from ever being created. We’ll wrap with the Toxic Trilogy, a practical model for spotting cloud assets that are statistically doomed, and show how PaC quietly dismantles all three conditions before anyone has to open a ticket.
