Keep your website secured and trusted with automated SSL certificate monitoring that runs 24/7. Catch issues before they impact your site or users. Reduce downtime and protect your reputation.

Why SSL/TLS certificate monitoring matters
SSL certificates are essential for protecting data, ensuring secure connections, and building user confidence. When a certificate expires or becomes invalid, it can instantly block access to your site and trigger scary browser warnings.
Testomato offers automated SSL monitoring that continually checks certificate validity and monitors upcoming expiration dates, keeping your website safe and secure.
SSL certificates are crucial for:
-
HTTPS encryption
Without a valid certificate, sensitive data goes unprotected and vulnerable to attacks. -
User trust
Modern browsers block or warn users about insecure sites with menacing warning messages. -
SEO performance
Search engines favor and reward HTTPS-enabled websites, making valid certificates a must. -
Brand credibility
A missing or invalid certificate immediately erodes trust and terminates user journeys. -
Prevent outages
Expired certificates can take down your site instantly. Early warnings eliminate that risk. -
Security standards
Ensure TLS protocols and encryption are always up to date and compliant.

SSL error detection & invalid certificate alerts
Expiration isn't the only reason certificates can fail. Testomato actively checks for:
Invalid certificates — Wrong issuer, self-signed, or revoked certificates.
Domain mismatch — Certificate doesn't match the domain name.
Weak encryption — Old TLS versions or insecure ciphers.
Missing chain — Missing or misconfigured intermediate certificates.
