Most SSL certificates for a domain are only valid for a certain period of time. After the period has expired, the certificate is declared invalid and the website visitor receives an error message. This error message informs the visitor that the certificate has expired and the site is therefore potentially unsafe. So you should make sure that your certificate is always valid. With our tool you can check the validity and find out how long it will expire. With Livewatch you also have the option of automating the monitoring of your SSL certificates. You will then receive a notification if your certificate is about to expire or is no longer valid for any other reason.
