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.
