Cloud Misconfigurations 2025

Cloud platforms like AWS, Azure, and GCP now run over 80% of modern applications.
But as businesses migrate faster than security teams can keep up, misconfigurations have become the #1 cause of cloud data breaches.

A single incorrect setting — a public bucket, an overly-permissive IAM role, or an exposed API — can leak millions of records.

This guide breaks down the most common cloud misconfigurations in simple, practical language and explains how to fix them in 2025.
