Check your SSL certificate for validity and expiration date. You can specify the
url to be checked and the minimum remaining term
min_days_left. If the certificate is invalid or falls below the specified period of validity, we will trigger the alarm. You should regularly check whether a certificate is still valid. Usually an expired or invalid certificate also means problems. Visitors who visit a website with an invalid certificate receive a warning message in the browser and usually avoid the confirmation to continue without a valid certificate.

An “SSL Certificate Check” refers to the verification of an SSL (Secure Socket Layer) certificate. SSL certificates are security protocols used to encrypt the transmission of data between a web browser and a web server. They play a critical role in protecting the privacy and security of user data, especially sensitive information such as credit card numbers and personal information.
The SSL Certificate Check is a process that checks the validity and integrity of an SSL certificate. Here are some of the main aspects taken into account during an SSL certificate check:
Validity: It is checked whether the SSL certificate is still valid. SSL certificates have a limited term, typically a year or longer. After expiry, the certificate must be renewed.
Certificate Chain: SSL certificates are organized in a hierarchy called a certificate chain. Verification ensures that each certificate in the chain was issued by a trusted Certificate Authority (CA).
Hostname Verification: The SSL certificate is usually issued for a specific hostname (domain). The SSL Certificate Check ensures that the host name accessed matches the host name specified in the certificate.
Algorithm and key length verification: The encryption algorithms and key lengths used should comply with security standards. Outdated or unsafe algorithms should be avoided.
Integrity of certificate information: It is checked whether the information contained in the certificate is correct and unchanged.
The SSL Certificate Check is important to ensure that communication between a user and a website is secure and that the website is trustworthy. Web browsers automatically perform SSL certificate checks and alert users if problems are detected with a certificate, such as if it has expired or was not issued by a trusted CA. Developers and system administrators also perform manual checks to ensure that all security aspects are met.
