CST VerdictBased on our analysis of available product data, here is our conclusion:
AWS teams with drift-heavy environments should start here; AWS Config catches resource configuration changes in real time at zero marginal cost, making it the fastest way to enforce consistency across accounts. It's native to AWS, deploys in minutes, and feeds directly into compliance frameworks like CIS Benchmarks and PCI DSS without additional licensing. Skip this if you need cross-cloud CSPM or deep remediation automation; Config excels at visibility and audit trails for AWS-only shops, not orchestration across Azure or GCP.
Security teams with limited budgets who need to audit their AWS account without vendor lock-in should start with AWS Security Toolbox; it bundles AWS's native tools,IAM Access Analyzer, Config, Security Hub,into a single container, eliminating the friction of stitching them together manually. The free pricing and 286 GitHub stars signal adoption by practitioners who've validated it works for baseline assessments and compliance checks. Skip it if you need continuous posture monitoring or remediation workflows; AST is a point-in-time scanner, not a platform replacement.
