CST VerdictBased on our analysis of NIST CSF 2.0 coverage, company size fit, deployment model, here is our conclusion:
Teams managing large AWS environments who need to eliminate excess IAM permissions without manual policy review will find AWS IAM Access Analyzer indispensable; it surfaces unused access across your account ecosystem and validates least privilege automatically. The tool covers NIST PR.AA and ID.AM functions directly, catching the permission creep that auditors flag every time. Skip this if your organization runs mostly outside AWS or treats IAM governance as a once-yearly compliance checkbox rather than ongoing hygiene.
Teams managing AWS and Azure environments who need to surface Cloud Shadow Admin risks should start with SkyArk; it's purpose-built to find privileged entities others miss, and the free tier means you can validate the finding in your own infrastructure before spending. The 904 GitHub stars indicate sustained adoption among practitioners who've stress-tested it against real multi-cloud setups. Skip SkyArk if you need CSPM breadth covering misconfiguration, data exposure, and compliance posture in one tool; it's narrow by design, solving the Shadow Admin problem exceptionally well rather than everything.
