CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Enterprise security teams managing complex attack surfaces across subsidiaries, cloud environments, and critical infrastructure should pick Censys Internet Map for its ability to discover assets an organization doesn't know it owns, which is where most breaches actually start. The platform covers asset discovery and continuous monitoring across ID.AM and DE.CM in NIST CSF 2.0, and its internet-wide scanning capability surfaces shadow IT and unknown exposures that traditional vulnerability scanners simply cannot reach. Skip this if your primary need is incident response or forensics; Censys is built for prevention and reconnaissance, not post-breach analysis.
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.
