SSL Certificate Monitoring Tool – Real-Time Expiration Alerts

What is SSL Certificate Monitoring?

SSL certificate monitoring is the process of continuously checking SSL/TLS certificates to ensure they remain valid, trusted, and unexpired. It helps prevent security warnings, downtime, and compliance issues caused by expired or misconfigured certificates.

What Is an SSL Certificate?

An SSL certificate is a digital certificate that enables encrypted communication between a browser and a web server. It verifies the website's identity and ensures data transmitted over HTTPS remains private and secure.

Modern SSL certificates use TLS (Transport Layer Security) to protect sensitive data such as login credentials, payment information, and personal data. More about TLS certificate you can find in RFC5246.

What Happens When an SSL Certificate Expires?

When an SSL certificate expires:

• Browsers display security warnings
• HTTPS connections may fail
• Users lose trust in the website
• Search rankings and conversions can be impacted

This is why SSL certificate expiration monitoring is essential for every website.

Why SSL Certificate Expiration Monitoring Matters

Expired SSL certificates can:

• Break secure connections
• Trigger browser warnings
• Damage user trust
• Cause service outages
• Violate security and compliance requirements

SSL certificate expiration monitoring ensures you are notified in advance, before certificates expire.

Frequently Asked Questions (FAQ)

How can I monitor SSL certificate expiration automatically?

By using an SSL certificate monitoring tool that continuously checks expiration dates and sends alerts before certificates expire. You can manage the alert threshold by yourself.

Is SSL certificate monitoring tool free?

Yes. You can use free SSL monitoring to track expiration dates and avoid unexpected outages for free.

How often should SSL certificates be monitored?

SSL certificates should be monitored continuously to detect expiration, revocation, or misconfiguration.

Can I monitor third-party SSL certificates?

Yes. You can monitor SSL certificates for any domain, including third-party services.

How long are SSL certificates valid?

Currently most SSL certificates are valid for 90 days to 1 year, depending on the certificate authority.

A major CA/Browser Forum ballot (SC-081v3) has been approved that will gradually shorten the maximum allowed validity periods for public SSL/TLS certificates even further over the coming years.

Until March 15, 2026 the validity period 398 days (13 months)

March 15, 2026 – March 15, 2027 validity period will be 200 days (~6.5 months)

March 15, 2027 – March 15, 2029 validity period will be 100 days (~3 months)

After March 15, 2029 validity period will be 47 days (~1.5 months)

These changes are defined by the CA/Browser Forum Baseline Requirements and ballots such as SC-081v3, which all major certificate authorities and browser vendors follow to maintain trust in SSL/TLS certificates globally.

Is SSL the same as TLS?

SSL is the predecessor to TLS. Today, SSL certificates actually use TLS encryption.

Why Are SSL Certificate Validity Periods Being Reduced?

• Limits exposure if a private key or certificate is compromised
• Forces more frequent validation of domain ownership
• Reduces the window for outdated cryptographic details to remain trusted
• Encourages automation in certificate lifecycle management (renewals, deployments)

These changes reflect ongoing industry priorities around enhanced security and risk reduction.

Do all websites need SSL certificates?

Yes. HTTPS is a standard requirement for security, user trust, and even for SEO.

How does SSL certificate expiration monitoring fit into website monitoring tools?

SSL certificate expiration monitoring is a critical part of modern website monitoring tools. While SSL monitoring ensures encrypted connections remain valid, combining it with DNS, domain, and email infrastructure checks provides full visibility into website availability, security, and trust.

Can domain monitoring and SSL alerts be managed together?

Yes. Domain monitoring and SSL alerts work best when combined. Monitoring domain status, DNS changes, and SSL certificate expiration helps detect issues that could impact availability, security, or ownership before they cause downtime.
