SSL certificate monitoring

Never get caught by an expired certificate

PageWarden tracks your certificate expiry and validates the chain on every check, so you hear about a problem days ahead, not from a customer looking at a browser warning. SSL monitoring is on every plan, including Free.

Everything one monitor is watching

What it checks

Expiry and chain, on every check

PageWarden reads the certificate on each check, tracks the days remaining until it expires, and validates that the chain is complete and trusted.

You see the exact expiry date and the days left, so a renewal never sneaks up on you.

Watches the full chain and the expiry date

A silent outage, caught early

Renew before browsers refuse the connection

An expiring certificate is a silent outage waiting to happen. PageWarden flags it while there is still time to act, not at the moment browsers start blocking the site.

Watch every certificate across your monitors from one board.

Uptime MonitoringPageWarden checks your site on a schedule, classifies every result up, degraded or down, and confirms a failure from multiple regions before it pages you.

The classic silent outage is a forgotten renewal, and this is how you avoid it. On every plan, including Free.See how it worksKeyword MonitoringPageWarden reads the page body and checks that specific text is present, or absent. It is an uptime check that looks past the status code, so you catch a broken checkout, a leaked error string, or a defacement.
