See what the internet knows about your domain
In seconds: whether anyone can send email in your name, when your site's certificate expires, and what is left unprotected. Explained in plain language, no jargon. Free, no sign-up.
We only look at public information about the domain: DNS records, the certificate the site presents, the date the domain was registered, and the site's home page, as any visitor receives it. We do not break into anything, we do not test ports, and we do not store your IP address.
This changes on its own
Certificates expire, DNS records get changed by mistake, redirects stop working. Today's check says nothing about tomorrow. We watch it for you and email you only when something changes.
Free for 1 domain, checked every week. For €9 per month: up to 5 domains, checked every day. No contract.
