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.
Development teams managing open-source dependencies across NPM and Python environments should use Hijacker to catch typosquatting and namespace hijacking before malicious packages reach production. The tool's free pricing and 309 GitHub stars reflect real adoption among developers who need this check integrated into CI/CD without budget friction. Skip this if your threat model assumes your supply chain is already vetted by a commercial software composition analysis platform; Hijacker is a point solution that finds one class of threat well, not a replacement for broader dependency scanning.
