SSL Certificate Checker - Bulk Expiry Monitor

Check SSL/TLS certificates for any domain in bulk. Identify expired, expiring, or misconfigured certificates across your entire domain portfolio.

What it does

For each domain, this actor connects via TLS and extracts complete certificate details including issuer, expiration, certificate chain, SANs, and negotiated protocol. Use it for:

Certificate expiry monitoring — find certificates expiring in the next 30/60/90 days
Security audits — verify certificate chains, signature algorithms, and TLS versions
Compliance checks — ensure all domains use current TLS standards
Domain portfolio management — bulk-check hundreds of domains at once
Vendor risk assessment — verify SSL health of third-party services

Input

Field	Type	Description
`domains`	Array of strings	Domains to check (e.g., `google.com`, `github.com`)
`maxResults`	Integer	Maximum domains to check (default: 100, max: 10,000)
