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.
DevOps and security teams building attack surface inventory integrations will get immediate value from Chaos Client because it's a lightweight, free API client that eliminates custom integration work against Chaos DB. The 763 GitHub stars and Go-native implementation mean you're deploying battle-tested code with minimal dependency overhead. Skip this if you need a UI-driven platform or dashboard; Chaos Client is for teams comfortable treating your attack surface data as an API-first resource to pipe into your existing toolchain.
