# SSL certificate monitoring

An expired certificate does not slow your site down, it stops it: every visitor meets a browser warning before they ever see a page. Ranetrace tracks how many days your certificate has left, alerts you before it runs out, and shows the issuer, protocol, signature and covered domains behind it. It works for any website, no code required.

## An expired certificate takes the whole site with it

When a certificate runs out, every visitor meets a browser warning instead of your site. Watching the expiry date, and the details behind it, is what keeps that from happening.

- **Days until expiry**: See how many days your certificate has left at the top of the page, with the status next to it. No manual check, no guessing.
- **Alerts before it expires**: Get notified before the certificate runs out, while there is still time to renew calmly instead of during an outage.
- **The certificate in full**: Issuer, issued date, TLS protocol version, signature algorithm, serial and fingerprint, all on one page.
- **Covered domains**: See every domain the certificate covers, so a subdomain that was left off the list does not surprise you later.
- **HTTPS check**: Every check confirms whether the site is actually served over HTTPS, not just whether a certificate exists somewhere behind it.
- **A verdict in plain language**: Every check ends with what was found, why it matters and what to do about it. You can pause the monitor in settings whenever you need to.

## And it loves Laravel and PHP


This check works on any website, no code required. Add the Ranetrace SDK to a Laravel or PHP app and the same site also gets [error tracking](https://ranetrace.com/features/error-monitoring.md), logs, and events from the inside, in the same dashboard where every check adds context to the others. Both SDKs also catch the JavaScript errors on your sites' frontends.
