SSL Certificate Monitoring

Never let an expired SSL certificate take your website offline. Watchman Tower continuously monitors your SSL certificates and alerts you well before they expire, helping you avoid browser warnings, SEO issues, and unexpected downtime.

SSL Certificate Monitoring is enabled automatically for every HTTPS monitor. There is nothing to install or configure.

Why SSL Certificate Monitoring Matters

SSL certificates quietly expire in the background—but the impact is immediate.

An expired certificate can cause:

• Browser security warnings that drive visitors away
• Lost customer trust and abandoned purchases
• Search engine visibility problems
• API and webhook failures
• Unnecessary emergency renewals

Instead of discovering the problem after customers report it, Watchman Tower warns you long before expiration.

Automatic SSL Certificate Monitoring

As soon as you add an HTTPS website, Watchman Tower automatically detects the SSL certificate and begins monitoring it.

There is no need to:

• upload certificates
• configure renewal dates
• maintain reminder calendars
• manually check expiration dates

Everything happens automatically in the background.

Get Alerts Before Certificates Expire

Watchman Tower checks your certificate at least once a day. Once fewer than 30 days remain, it checks every 6 hours, and in the final week every 2 hours. Each check compares the remaining lifetime against fixed alert thresholds.

You'll receive reminders:

• 30 days before expiration
• 14 days before expiration
• 7 days before expiration
• 3 days before expiration
• 1 day before expiration

This gives your team plenty of time to renew certificates before visitors ever see a browser warning.

Where Alerts Are Delivered

SSL expiration reminders are delivered through:

• Email
• Push notifications in the Watchman Tower mobile app
• Notifications in your Watchman Tower dashboard

All three channels are included on every plan.

Monitor Every Website Automatically

Whether you monitor:

• WordPress websites
• SaaS applications
• APIs
• Marketing sites
• Customer portals and dashboards

As long as the site is reachable over HTTPS from the public internet, Watchman Tower checks its certificate alongside uptime and response time.

SSL monitoring becomes part of your normal monitoring workflow instead of a separate maintenance task.

Works Together with Uptime Monitoring

SSL certificate monitoring is only one part of website reliability.

Watchman Tower combines SSL monitoring with:

• Uptime Monitoring
• Response Time Monitoring
• Domain Expiry Monitoring
• Smart Alerts
• Incident History

This gives your team a complete picture of website health instead of isolated checks.
