10 AWS Security Misconfigurations Found in 90% of Accounts

import { FaqSection } from "@/components/mdx/faq-section"; import { CtaCard } from "@/components/mdx/cta-card"; I've reviewed over 200 AWS accounts across startups and enterprises. These 10 security misconfigurations appear in more than 90% of them, and most teams don't know they exist until something goes wrong. The difference between a good review and a great one is how findings are prioritized and presented so you can actually act on them. For a complete breakdown of the review process, see our AWS security review process guide. AWS security misconfigurations are incorrect settings in cloud infrastructure that expose resources to unauthorized access, data breaches, or service disruption. Unlike software vulnerabilities requiring patches, misconfigurations result from human error, default settings that aren't secured, or operational shortcuts that become permanent. Cloud misconfigurations cause over 80% of security breaches, making this the most impactful security work you can do. Th
