CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Teams building an initial asset inventory across sprawling AWS accounts should start with AWS Resource Discovery because it discovers what you actually have before you can defend it, and the free price tag means zero friction to run it today across dev and prod environments. The tool catalogs resources in JSON format via botocore, giving you the raw material to feed into downstream CSPM or CIEM tools rather than replacing them. Skip this if you need continuous monitoring or remediation workflows; it's a one-time discovery pull, not a persistent control plane.
Startups and SMBs without dedicated asset management infrastructure should run Open-AudIT first; its agentless discovery requires zero endpoint overhead and maps your entire network inventory in days, not months. The tool covers ID.AM and DE.CM effectively with 50+ built-in compliance reports and distributed collector support across subnets, giving you baseline visibility cheaply. Skip this if you need vulnerability scanning or incident response integration; Open-AudIT is pure discovery and asset tracking, not a platform that connects to your SIEM or threat intel feeds.
