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 managing GitHub organizations with loose access controls or unknown repositories will find GitRob valuable for the speed of its initial reconnaissance; it maps org structure, identifies service accounts, and surfaces exposed secrets faster than manual audit, and the 6,000-plus GitHub stars reflect sustained adoption by teams doing this work at scale. Skip this if your org has already inventoried all repositories and locked down branch protection policies; GitRob is a discovery tool for the messy middle, not a compliance validator.
