CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Security teams doing threat intelligence or domain monitoring should use crt.sh as a free, fast way to spot certificate issuance anomalies that signal domain takeover or phishing campaigns before they scale. Certificate Transparency logs index roughly 15 billion certificates, giving you real-time visibility into what's been legitimately issued against your domains and competitors' infrastructure. Skip this if you need automated alerting or integration into your SIEM; crt.sh is a lookup tool, not a monitoring platform, and catching malicious certificates requires manual checks or custom scripting.
SOC Radar Attack Surface Management
Mid-market and enterprise security teams drowning in unmanaged internet-facing assets will get immediate value from SOC Radar Attack Surface Management because it actually finds what you don't know you have, then stays on top of it continuously. The platform covers the full ID.AM to ID.RA to DE.CM chain: asset discovery, risk scoring, and persistent monitoring across shadow infrastructure, which means you're not stuck doing quarterly manual audits. Skip this if you need tight integration with existing GRC workflows or expect hand-holding during deployment; SOC Radar assumes you can operationalize findings without heavy professional services.
