SSL certificate monitoring
We check your SSL certificate around the clock (expiry, issuer and chain) and warn you in plain English before a visitor ever sees a security warning.
Every new account gets 30 days with almost everything unlocked — no card required.
An expired certificate turns visitors away
When a certificate lapses, browsers show every visitor a full-page security warning, usually discovered at the worst possible moment. We make sure that moment never arrives by surprise.
Every certificate, checked day and night
We check your certificate every few hours — its expiry date, who issued it, and whether the chain validates back to a trusted root — and give you a clear Healthy, Needs attention or Down at a glance.
- Expiry, issuer and full chain validation
- Early warning up to 30 days before renewal is due
- On every plan, including Free
See it on the dashboard the moment it changes
A certificate that needs attention shows up on your dashboard right away, so a problem on one client's site never hides among the rest.
- Healthy / Needs attention / Down across every site
- The site that needs you, surfaced first
- No dashboards to decode

Questions you might have
It means we check your site's certificate around the clock (its expiry date, who issued it, and whether the chain is valid) and warn you in plain English if anything's about to go wrong. You find out before a visitor ever sees a security warning.
Every few hours, on every plan including Free. Certificates don't change minute to minute, so a few-hourly check catches problems in good time without the noise.
Yes. We flag a certificate approaching its expiry date well ahead of time (up to 30 days in advance) so renewing is a calm task, not a midnight scramble.
Yes. We validate the certificate itself plus the chain back to a trusted root, and flag issues like an untrusted issuer or a self-signed certificate, not just the expiry date.
Browsers stop trusting it and show every visitor a full-page security warning that blocks them from reaching your site. We mark the site Down the moment it happens and alert you, but the point is to warn you long before it gets that far.
