Based 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 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.
Security teams responsible for external asset discovery and exposure monitoring should start with ONYPHE because it operates as a passive reconnaissance engine, finding exposed infrastructure without requiring agents or API integrations across your estate. The free tier lets you baseline your internet-facing attack surface immediately, which matters for teams under budget pressure or those running initial scans before committing to a paid EASM tool. Skip this if your priority is vulnerability assessment and remediation workflows; ONYPHE finds what's exposed but doesn't deeply score or manage patch prioritization across discovered assets the way purpose-built EASM platforms do.
