SSL Monitoring

Stay ahead of certificate expiry — before browsers start warning your visitors away.

An expired SSL certificate can kill your business overnight

When an SSL certificate expires, browsers immediately show visitors a full-screen security warning. Most people won’t click through — they’ll leave and never come back. And the worst part? It’s completely avoidable. Monitero tracks your certificate and alerts you weeks before it becomes a problem.

Beyond expiry, Monitero checks for hostname mismatches, untrusted certificate authorities, and verification failures — the kind of issues that can silently break your site without a single obvious error. If something is wrong with your SSL, you’ll know about it before your customers do.

How it works

How SSL monitoring works

Monitero continuously verifies your SSL certificates to ensure they remain valid and trusted.
Receive proactive alerts before expiration and instant notifications when problems occur.

We connect to your server

Monitero opens a secure connection to your server and inspects the SSL certificate directly — checking expiry date, issuer, hostnames, and validity.

We track the countdown

Your certificate’s days remaining are logged on every check. As expiry approaches, we move your monitor to a warning state at 14 days and critical at 3 days.

We alert you in
advance

You get a warning alert at 14 days and a critical alert at 3 days — plenty of time to renew before anything breaks.

More than just expiry tracking

SSL monitoring should go beyond checking expiration dates. Monitero verifies certificate validity, trust chains, and configuration issues to keep your connections secure.

Expiry countdown

We track exactly how many days remain on your certificate and alert you at 14 days and again at 3 days — well before any browser warnings appear.

Certificate authority checks

Monitero flags self-signed certificates and untrusted certificate authorities — the kind of SSL issues that browsers reject and users never understand.

Hostname validation

We verify that your certificate is valid for the exact domain it’s serving. A mismatch triggers an immediate alert, even if the certificate itself hasn’t expired.

Full certificate details

See your certificate’s issuer, subject, and all covered domain names (SANs) in your dashboard — everything you need to stay on top of your SSL health.

Our site was down for two hours before we even knew. With Monitero I got an alert within a minute. It completely changed how we manage our site.
