CST Verdict

Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:

Aleph Search Clear

Mid-market and enterprise security teams managing third-party and supply chain risk need Aleph Search Clear because it finds exposure across both surface and deep web in a single query, then automates the monitoring that actually catches when your vendors get compromised. The tool covers five NIST CSF 2.0 functions from asset discovery through adverse event analysis, and its KYC/KYS alignment with DORA and NIS 2 saves compliance teams weeks of manual mapping work. Skip this if your organization only needs traditional OSINT for incident response; Aleph is built for continuous ecosystem risk oversight, not one-off research.
