CST VerdictShort answer
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. Mid-market and enterprise teams deploying AI agents at scale need SecureG Agentic AI PKI to stop treating non-human identities as an afterthought; it's the only PKI vendor purpose-built for cryptographic credential lifecycle at agent velocity. The cloud-native PKIaaS model eliminates the certificate sprawl and expiration chaos that plague teams running dozens of agents across microservices, and covers NIST PR.AA and supply chain risk management by design. Skip this if your organization runs fewer than five AI agents or hasn't yet mapped your cryptographic inventory; the quantum-safe migration overhead won't justify itself until scale hits.
