CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Mid-market and enterprise security teams managing sprawling external infrastructure will get the most from Assetnote ASM because its hourly asset discovery actually catches exposures before your business units spin up new services, not weeks after. The platform covers ID.AM and DE.CM across NIST CSF 2.0, meaning you're building a real asset inventory while monitoring it continuously, and the exploit-based verification eliminates the noise that buries actionable findings in traditional scanners. Skip this if your organization lacks the headcount to operationalize a workflow-driven program; Assetnote's strength is enabling lean teams to prioritize, not giving you a dashboard to ignore.
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.
