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 buried under sprawling cloud infrastructure will get real value from Edgescan Attack Surface Management because it actually finds the assets you've forgotten you own, not just rescans what's already in your inventory. The platform maps DNS records, subdomains, and APIs continuously without requiring agents or network access, covering ID.AM and ID.RA in NIST CSF 2.0 where most ASM tools go shallow. Skip this if your priority is remediation workflow automation or integration with existing ticketing systems; Edgescan excels at discovery and exposure alerting, not orchestration of the fix.
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.
