Over the past two years, CSI’s Cloud Security practice has conducted more than 200 multi-cloud security assessments across AWS, Azure, and GCP environments.

Misconfigured storage buckets remain the single most common finding, present in 67% of assessments. Overly permissive IAM roles appear in 58% of environments. Lack of network segmentation between workloads is found in 71% of multi-cloud deployments.
