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 doing reconnaissance on unfamiliar domains or investigating potential supply chain risks will find WayMore valuable for its ability to aggregate disparate data sources into a single query, saving hours of manual OSINT work across multiple tools. The 2,167 GitHub stars reflect active community trust and continuous refinement. Skip this if your team needs automated, continuous monitoring of your own attack surface rather than ad hoc lookups; WayMore is a lookup tool, not a persistent scanning platform.
