What you get per domain

Field	Description
`daysUntilExpiry`	Days left before the certificate expires (negative = already expired)
`expiresOn`, `issuedOn`	Validity period
`issuer`, `issuerOrg`	Certificate authority (Let's Encrypt, DigiCert, Sectigo…)
`sslValid`	Whether the certificate passes standard validation
`hostnameMatches`	Certificate actually covers this hostname
`selfSigned`	Self-signed certificate
`altNames`	All domains covered by the certificate
`tlsVersion`, `cipher`	Negotiated TLS version and cipher
`httpsRedirect`	Whether HTTP redirects to HTTPS
`hsts`	Strict-Transport-Security header present
`expired`, `expiringSoon`	Ready-to-filter flags

Use cases

Monitoring: schedule a daily run and get alerted before any client certificate expires
Agencies: check every site you maintain in one run instead of one by one
Sales: find prospects with expired or invalid certificates — an easy first conversation
Security audits: spot old TLS versions, hostname mismatches and self-signed certificates
Mail servers: set the port to 465 or 993 to check mail certificates

Only problems mode

Turn on Only return problems and the Actor returns only domains with expired, expiring, invalid or unreachable certificates. Healthy domains are skipped and not charged — a cheap way to monitor a large portfolio.

Automate it

Schedule the Actor to run daily and connect it to Slack, email or a webhook through Apify integrations (Make, Zapier, n8n) to get notified automatically.

Pricing

You pay per domain checked. Unreachable domains are returned for free.
