Never get caught out by an expiry
If your website's padlock runs out, every visitor sees a warning. If your domain name runs out, your website and your email stop working. We check both every day and email you first. It's free, and there's nothing to install.

What we look at
Your website's padlock
Once a day we connect to your website the way a browser starts to, and read when its padlock runs out and who issued it. We don't load the page.
Your domain name
Once a day we read the date your domain name runs out, from the public record kept by the people who run that ending (like .com or .uk). Some don't publish a date. Then we tell you, rather than guess.
What we don't do
We don't explore your website, scan it or try to log in. We also refuse any name that points inside a private network.
For your IT person
The certificate: one TLS connection to the domain on port 443, the way a browser starts, to read the certificate's expiry date and issuer; the page is not fetched. The registration: the expiry date the domain's registry publishes through RDAP (the successor to WHOIS); where a registry publishes none, we record that and say so. Each name is resolved by us, and anything pointing at a private or internal address is refused. Reminders: certificates 7, 3 and 1 days before expiry, registrations 30, 14, 7 and 1 days before, one notice if either passes, at most one email a day per subscriber covering all their domains. Up to 5 domains per address. Email is sent through Proton (SMTP submission) with one-click unsubscribe (RFC 8058) in every message.
