About our security & domain tools
Tools for checking the infrastructure around a website: when SSL certificates expire, how old a domain is and when it renews, and building correctly-tagged campaign URLs.
Live lookups
The SSL checker opens a real TLS connection to each host and reads the certificate the server presents. The domain age checker asks IANA which registry is authoritative for the TLD and queries that WHOIS server directly over port 43.
Why monitor in bulk
Expired certificates and lapsed domains are almost always an oversight across a portfolio of sites, not a single one. Checking every domain you manage in one batch is the quickest way to catch the one that is about to expire.
Registry privacy
Since GDPR, most registries redact registrant names and contact details. Dates, registrar and status are still public and are what these tools report.
