Never let an SSL certificate expire unnoticed. Proactive expiry alerts, certificate chain validation, and automatic tracking for every HTTPS monitor.
An SSL certificate is the foundation of trust on the modern internet. When visitors see the padlock icon in their browser address bar, they know that their connection to your website is encrypted and that the site has been verified by a trusted Certificate Authority. But when that certificate expires, everything changes. Browsers display alarming security warnings like "Your connection is not private," visitors leave immediately, and search engines begin penalizing your site in their rankings.
Despite the critical importance of SSL certificates, certificate expiry remains one of the most common causes of preventable website outages worldwide. Even large organizations with dedicated IT teams have experienced embarrassing public incidents caused by forgotten certificate renewals. The reason is simple: SSL certificates expire silently. There is no built-in alarm in your server that warns you when expiry is approaching. Without active monitoring, the first sign of a problem is often a flood of customer complaints.
UptimeMonitorX solves this problem completely. Every HTTPS monitor you create automatically includes SSL certificate monitoring at no extra cost. Our system checks your certificate with every uptime check, calculates the days remaining until expiry, verifies the certificate chain, and sends you timely alerts through Email, Slack, Telegram, Discord, or WhatsApp so you always have time to act before expiry causes damage.
Receive proactive alerts 30, 14, 7, and 1 day before your SSL certificate expires. UptimeMonitorX calculates the days remaining on every HTTPS check and notifies you well in advance, giving you plenty of time to renew before your visitors see browser security warnings.
Verify that your SSL/TLS certificate is valid, properly signed, and trusted by all major browsers and operating systems. UptimeMonitorX checks the certificate chain from your server certificate up to the root Certificate Authority (CA) to detect any misconfigurations or broken links.
Check the complete certificate chain to ensure all intermediate certificates are correctly installed. A missing or misordered intermediate certificate can cause trust failures in certain browsers even when the root certificate is valid, leading to inconsistent behavior across devices.
SSL certificate monitoring is automatically enabled for every HTTPS monitor you create - no extra configuration, no additional cost, no separate setup step. The moment you add an HTTPS website to UptimeMonitorX, SSL monitoring begins immediately.
View comprehensive certificate details at a glance from your monitoring dashboard: issuer name, subject (domain), validity start and end dates, serial number, signature algorithm, and the number of days remaining until expiry. All the information you need in one place.
Get immediate alerts if your SSL certificate becomes invalid, revoked, or misconfigured at any point during its lifecycle. Whether it is a botched renewal, an accidental overwrite, or a hosting provider error, UptimeMonitorX catches the issue before your visitors do.
Monitor SSL certificates on any domain, including multi-domain (SAN) certificates and wildcard certificates. Each HTTPS monitor independently tracks the certificate presented by that specific endpoint, so you can monitor certificates across all your domains from a single account.
Maintain a history of certificate changes over time. Track when certificates were renewed, which issuer was used, and how the certificate configuration has evolved. This data is invaluable for compliance audits and troubleshooting certificate rotation issues.
No. SSL certificate monitoring is automatically included with every HTTPS monitor. When you add an HTTPS URL, UptimeMonitorX immediately begins tracking the SSL certificate validity and expiry - no additional setup required.
UptimeMonitorX sends expiry alerts at 30, 14, 7, and 1 day before your certificate expires. You can also see the remaining days on your dashboard at any time for all monitored certificates.
Yes. UptimeMonitorX works with any SSL/TLS certificate regardless of the issuer - Let's Encrypt, DigiCert, Comodo, GoDaddy, Cloudflare, or any other Certificate Authority. The monitoring checks the actual certificate presented by your server.
