CST VerdictBased on our analysis of available product data, here is our conclusion:
Security teams managing sprawling AWS environments need aws_public_ips to find what they've actually exposed across EC2, CloudFront, ELB, RDS, and other services in minutes, not weeks of manual inventory work. The tool's 642 GitHub stars reflect its adoption among practitioners who value speed and specificity over UI polish. Skip this if your organization already has a mature CSPM feeding real-time asset data into your EASM platform; aws_public_ips shines as a quick audit tool or gap-filler, not as a continuous monitoring layer.
AppSec and cloud infrastructure teams hunting for S3 misconfigurations tied to their own domains should start with FestIn; it's free, which means you can run it immediately without budget cycles, and the DNS reconnaissance approach catches buckets that simpler bucket-enumeration tools miss. The 230 GitHub stars suggest active maintenance and community validation of the crawling methods. Skip this if your threat model requires continuous monitoring or remediation workflows; FestIn is a point-in-time discovery tool, not a compliance scanner.
