Everything ssl & domain expiry covers
Certificate expiry
Days left on every certificate, with an early warning when auto-renewal seems to have failed.
Certificate validity
Whether browsers trust the certificate: right name, complete chain, not self-signed.
Issuer
Which authority issued it, so you know whether it renews automatically (Let’s Encrypt) or must be bought.
HTTPS redirect
Whether visitors on http:// are sent to the secure version.
Domain registration expiry
The registration end date where the registry publishes it, with a reminder to renew.
Nameserver changes
An alert when the DNS provider of a domain changes unexpectedly.
Small problems, big consequences
Certificates are supposed to renew themselves, until a DNS change or server move breaks auto-renewal and nobody notices. When the certificate or the domain lapses, the site is effectively offline for every visitor.

Frequently asked questions
How early do you warn?
For certificates that don’t auto-renew we warn at 30 days; for any certificate we escalate to critical at 14 days.
Can you see domain expiry for .nl domains?
SIDN doesn’t publish expiry dates for .nl, so we show it for domains where the registry does (.com, .net, .io and many more).
Do you check the www version too?
We check the certificate on the domain you add, including which names it covers.
What if I use Cloudflare?
That works fine. We check the certificate visitors actually see.
