CST VerdictBased on our analysis of available product data, here is our conclusion:
Security teams auditing their cloud footprint without a dedicated budget will find Cloud_enum invaluable; it's free, open-source, and catches publicly exposed resources across AWS, Azure, and GCP that paid tools often miss during initial reconnaissance. The 2,036 GitHub stars and active community contributions signal real-world adoption among practitioners who validate its enumeration accuracy. Skip this if you need continuous monitoring or remediation workflows; Cloud_enum is a point-in-time scanner best run monthly or before major assessments, not a runtime detection tool.
Security teams conducting external attack surface reconnaissance on cloud infrastructure should use s3viewer for its speed in discovering publicly exposed storage across multiple cloud providers and protocols from a single interface. The tool is free and requires no credentials to operate, making it immediately deployable for red team assessments or initial exposure audits without procurement friction. Skip this if you need ongoing monitoring or remediation workflows; s3viewer is a point-in-time discovery tool, not a continuous posture management platform.
