CT logs are an immutable, append-only record of every certificate issued by participating Certificate Authorities (CAs), as required by the major browsers since 2018.
Subdomain enumeration via CT logs is one of the highest-signal techniques in reconnaissance — every time a TLS certificate is issued, all Subject Alternative Names (SANs) on that certificate become public. Internal and forgotten subdomains regularly show up here days after they're set up.
To monitor replica-cyan.oregon-postgres.render.com for newly-issued certificates in real-time (useful for detecting unauthorized issuance, phishing variants, or shadow IT) add it to your watchlist (Pro plan).
